Why Is My Garage Door So Heavy to Lift?

Q: How heavy should a garage door be to lift by hand?

The published criterion is positional rather than a weight. DASMA's inspection checklist asks whether the door moves “freely, without difficulty, and not more quickly than force applied,” and whether it will “stay in the partially open position 3-4 feet above the floor.” Both yes means balanced. The trade's shorthand for the same thing is about 10 pounds at the handle — roughly a full bag of groceries — and that's a useful field rule of thumb rather than a standard. The door itself can weigh anywhere from 90 pounds to over 500, per DASMA; the springs offset almost all of it. If lifting takes real effort, the counterbalance no longer matches the door.

Q: Should a garage door be heavy to lift?

No. A correctly balanced door feels light regardless of what it actually weighs, because the spring system is storing almost exactly the door's weight and canceling it out. Heaviness is always a sign that the two sides of that arrangement no longer match — either the springs have weakened, they were never right for the door, or weight has been added since.

Q: Why has my garage door suddenly got heavy?

Sudden means something failed rather than wore. A broken spring is the usual answer — look for a clean gap in the coil above the door. A cable off its drum is the other candidate, and that one usually shows up as the door being heavy and uneven rather than heavy and level. Both mean the door shouldn't be operated until they're addressed.

Q: Can a garage door be too heavy for the opener?

It always was. Openers are built to nudge a balanced door and hold position, not to lift a few hundred pounds. When the counterbalance falls behind, the opener quietly covers the difference on every cycle, and the nylon drive gear inside it is deliberately the part designed to fail first when that goes too far.

Q: My garage door is heavy but nothing looks broken. What's wrong?

Most likely springs that have lost tension without breaking, which is completely invisible from the outside. It's also worth checking whether anything was added to the door — an insulation kit, replacement sections, glass, years of repaint — since weight added without re-sizing the springs produces exactly this. On extension-spring doors, a permanent stretch does the same thing while the spring looks perfectly intact.

Q: Does insulating a garage door make it heavier?

Yes, meaningfully, and it's a common cause of a heavy door in this valley because insulating a garage here is a sensible thing to do. The problem isn't the insulation — it's fitting it without re-matching the springs to the door's new weight. Raise it before the work rather than discovering it two years later.

Q: How do I test if my garage door is balanced?

Door closed, opener unplugged, emergency release pulled, then lift by hand using the handles or gripping points — never with your fingers between the sections — and take it to three or four feet. Let go. DASMA's criterion is that it stays in that partially open position and that it moved freely, no faster than the force you applied. It should also feel like about ten pounds, though that's the field version rather than the standard. The full method, including what each result means, is on our garage door balance test page — worth following rather than improvising, since how you do it affects what the answer means.

Q: Is a heavy garage door dangerous?

It's a condition worth acting on rather than an emergency in itself. The specific risks are that the opener is carrying a load it wasn't designed for, that a door which no longer holds position can move when you don't expect it to, and that under-sprung springs are working beyond their design and heading toward failure. A door that's heavy and uneven is a different and more urgent situation.

Q: Can I fix a heavy garage door myself?

You can address the friction half of it — clearing grit from the track bottoms and lubricating rollers, hinges and bearings with silicone or white lithium grease. That's genuinely worth doing. What you can't address is the counterbalance, because adjusting spring tension means handling stored energy that's holding the door's entire weight. That part is a garage door spring repair, and it's the one item on the list worth handing over.

Q: Why is one side of my garage door heavier than the other?

That isn't a balance problem. Uneven effort means one side has lost support — a cable off its drum, a drum that has slipped, or a snapped cable. It is not caused by one of two torsion springs breaking, since both springs share a single shaft and a failure makes the door uniformly heavy. Stop operating it and have the cables looked at.

Short answer first, because it's the thing nobody says plainly.

The industry test for a garage door isn't a weight — it's a position. DASMA's inspection checklist asks two questions: does the door “move freely, without difficulty, and not more quickly than force applied,” and does it “stay in the partially open position 3-4 feet above the floor”? A door that does both is balanced. A door that fails either one is not, and that's the answer regardless of how it feels.

In the field we translate that into a number, and it's the number people actually want: a balanced door feels like roughly 10 pounds at the handle, about a full bag of groceries. Be clear about what that figure is, though — it's a technician's rule of thumb, not a published standard. The 3-to-4-foot hold is the citable criterion. The two agree in practice, and if you only remember one, remember the hold.

As for what you're actually offsetting: DASMA puts garage doors at “anywhere from 90 pounds to over 500 pounds.” The residential sectionals we work on across Mesa and Gilbert mostly run 130 to 350 depending on size, material and insulation — that narrower band is our own count off service calls, not a published figure. Either way, you were only ever meant to feel about ten of those pounds. The springs carry the rest.

So if lifting your door by hand takes real effort, nothing about the door has gotten mysteriously heavier. What's changed is how much of its weight the counterbalance is still offsetting. Every cause below is a version of that same sentence.

This is worth taking seriously even when the opener still manages it, because the opener managing it is exactly the problem: the motor is quietly making up the difference, and it's rated for a nudge rather than a lift.

⚠ High risk — leave this to a technician Involves high-tension components or the door’s full weight. This is where people get badly hurt.

This is general guidance based on what we see on service calls — it isn’t a substitute for someone looking at your actual door. Every door is a little different, and if anything here feels beyond what you want to take on, stop and give us a call.

What to check in the next 10 minutes

Four questions that place the problem before anybody touches a wrench.

1
Decide whether it's heavy or just hard to start
There's a real difference between a door that resists the first six inches and then moves freely, and one that fights you the whole way up. The first points at friction, a stuck seal, or a bind at the bottom of the track. The second points at the counterbalance. Try it and notice which you have.
You’ll know it worked when: You can say whether the resistance is at the start or throughout.
2
Check whether it holds position
Lift the door partway — DASMA's checkpoint is three to four feet above the floor — and let go, carefully, standing to one side and ready for it to move. A balanced door stays put. A door that sinks is under-sprung. A door that keeps rising is over-sprung. This single observation separates most of the causes below from each other.

How you hold the door matters as much as the result. Use the handles or gripping points; a residential sectional door is required to have four of them, two inside and two out, within eight inches of the bottom edge of the bottom section. Never put your fingers between the sections. DASMA's wording on that is not soft: the section-to-section joint “is not a suitable gripping point” and gripping there “could result in serious injury.” The sections close on each other as the door moves.
You’ll know it worked when: You know whether the door holds, sinks or climbs when you release it at three to four feet — and you did it holding the handles rather than the joint.
3
Look at the spring for a gap
A clean break in the coil above the door ends the diagnosis immediately — that's a broken spring rather than a heavy door, and it goes to a different page. Check before spending time on anything else, since it takes ten seconds and it rules out the biggest single cause.
You’ll know it worked when: You've looked at the coil and can say whether it's continuous.
4
Ask when it changed
Sudden or gradual. A door that got heavy overnight has had something break. A door that has been getting heavier over a year or two has springs losing tension, or hardware getting stiffer, or both. People are usually surer about this than they expect once they think back.
You’ll know it worked when: You can put the change on a timeline, even roughly.

Sudden, or gradual?

This is the fork that splits the whole page, and most people can answer it without going out to the garage.

Did the door get heavy all at once, or has it been getting worse over months?

All at once — it was fine last week

What that means: Something has failed rather than worn. A broken spring is the overwhelming favorite, followed by a cable that has come off its drum. Both are visible from where you're standing, and both mean the door shouldn't be operated until they're dealt with.

Where to go next: Read causes 1 and 7, and check the coil.

Gradually, over a year or more

What that means: Springs losing tension, hardware accumulating friction, or weight added to the door somewhere along the way. All three are real, all three are common, and they frequently stack — which is why a door can get noticeably heavy without any single dramatic cause.

Where to go next: Read causes 2 through 6.

It has always been heavy, since we moved in

What that means: Then it was probably never right. Springs that were undersized at install, or that were never re-matched after the door was changed, produce a door that has been slightly wrong its whole life and that nobody has a baseline for.

Where to go next: Read cause 3.

Worth answering honestly rather than optimistically. “It's been a bit heavy for a while” and “it got heavy on Tuesday” lead to genuinely different conversations.

The different flavors of heavy

Where in the travel the door fights you tells you a surprising amount.

Heavy through the entire lift, top to bottom

The counterbalance is short of what the door needs. Springs, in one form or another.

Jump to that fix ↓

Sticks hard for the first few inches, then moves freely

Something at the bottom — a seal bonded to hot concrete, grit packed in the track, or a bind at the bottom rollers.

Jump to that fix ↓

Fine at first, then heavy near the top

Friction that increases through the travel, typically in the horizontal track or the top rollers.

Jump to that fix ↓

Heavy, and it drops back down when you let go

Under-sprung. The springs aren't producing enough lift to hold the door where you put it.

Jump to that fix ↓

Almost immovable, with a gap in the coil above the door

A broken spring. Not a heavy door — a door with no counterbalance at all.

Jump to that fix ↓

Heavier on one side, and the door racks as it rises

A cable or drum problem rather than a spring one. Different page, more urgency.

Jump to that fix ↓

Got heavy after the door was insulated or repainted

Weight was added and nobody re-matched the springs to it.

Where the ten pounds comes from

Picture a see-saw with your door on one end. On the other end is a spring, wound up to store almost exactly the door's weight. When the two match, the door floats — you can move it up or down with modest effort, and it stays wherever you stop it, because there's nothing left over to pull it either way.

That leftover is what you feel in your hands. On a correctly counterbalanced door it's small: about ten pounds, give or take, whether the door itself weighs 140 pounds or 300. Treat that ten as a working estimate rather than a specification — it's how the trade describes the feel, and no standard publishes it. What the standards describe instead is behavior: the door moves without difficulty, no faster than the force you apply, and it stays put at three to four feet. The counterbalance is deliberately set a touch under the door's weight so a door left partway drifts down rather than up, but the margin is small enough that it barely registers.

Now take some of the spring's contribution away — because it's fatigued, or undersized, or because you added weight to the door and never re-matched it. The see-saw stops balancing. What you feel isn't ten pounds anymore, it's ten plus however much the spring is now short by. That's the entire mechanism, and it's why a door can go from effortless to genuinely hard over a couple of years without anything visibly breaking.

There's a second contribution, which is friction. Rollers, hinges and bearings all add drag, and drag doesn't care which direction you're moving — it makes the door harder to lift and harder to lower, and it can make an under-sprung door feel deceptively balanced because it's holding position through stiffness rather than through counterbalance. That's why a heavy door that also feels rough is two problems rather than one.

Balanced The point where spring lift and door weight nearly cancel. The checkable version: the door moves freely, no faster than the force applied, and stays put three to four feet above the floor. In the hand it feels like about ten pounds.

Under-sprung Springs producing less lift than the door weighs. Heavy to lift, sinks when released.

Over-sprung Springs producing more lift than the door weighs. Light to lift, climbs when released, slams the door open.

Drag Friction from rollers, hinges and bearings. Resists movement in both directions and masks a balance problem.

The thing worth remembering: your door's weight is a fixed number that hasn't changed. Everything on this page is about the other side of the see-saw.

What’s actually causing it

These are ordered the way we work through them on a real service call — cheapest and most common first, so you don’t start by replacing a part that was never the problem.

A spring has broken

High risk — call a technician

The extreme version, and the first thing to rule out because it takes ten seconds. A broken torsion spring shows a clean gap in the coil above the opening, an inch or two wide, as though a section had been removed.

When that happens there's no counterbalance left at all, so the door isn't heavy in the sense this page mostly means — it's simply the door's whole weight, all of it, in your hands. Nothing on the friction or adjustment side of this page applies.

The mechanism, the warning signs and what to do next are covered properly on the broken-spring page rather than repeated here.

How you can tell: A visible gap in the coil. Door that goes down under power but won't come back up. Often a bang somebody in the house heard.

Where to stop: Unplug the opener and leave the door alone. Running it against a broken spring loads the opener's nylon drive gear against a door it can't lift, and that gear is designed to be the part that gives out.

The springs are losing tension without having broken

High risk — call a technician

The most common cause of a door that has become gradually heavy, and the one that produces almost no drama at all.

Springs don't hold their rated lift forever. As cycles accumulate and the steel fatigues, a spring produces slightly less lift than it did. It's a small change per year and it's cumulative, so the door gets heavier at a pace nobody notices day to day. Households adapt — somebody starts using two hands, somebody comments that the opener sounds tired — and the change gets absorbed rather than reported.

What makes this worth catching is that the door is still working. Under power it opens, and the motor makes up the deficit every cycle, which is exactly the load path an opener isn't built for. That's how a spring problem quietly becomes an opener problem months before the spring finishes failing.

The definitive check is the manual balance test, which is covered step by step on its own page. Run that rather than guessing at it.

How you can tell: The door has been getting heavier over a year or more. It sinks when released partway. The opener sounds like it's working harder than it used to and the door travels more slowly.

Where to stop: Don't compensate by increasing the opener's force setting. That hides the change, spends the safety margin that makes the door reverse on an obstruction, and leaves the spring exactly as fatigued as it was.

The springs were never right for this door

High risk — call a technician

Some doors have been slightly heavy their whole lives, and nobody knew because there was no before to compare against.

A torsion spring's lift comes from a specific combination of wire diameter, inside diameter and length. Match those to the door's actual weight and the see-saw balances. Get it approximately right and it approximately balances, which means the door is a little heavy from the first day and the springs are working slightly beyond what they were built for on every cycle.

We find this most often after a spring was chosen by matching the old part rather than by weighing the door, or bought online on the strength of looking similar. It also turns up on houses where a builder specified a package and the door that eventually went in wasn't quite the door the springs were for.

The tell isn't a symptom so much as a history: a door that has always felt like more work than it should, and springs that seem to fail more often than the arithmetic predicts.

How you can tell: It has felt heavy since you moved in or since the last spring replacement. Often paired with a spring life that seems short for how little the door is used.

Where to stop: This is a reason to ask, at replacement, how the spring size was arrived at. “We matched the old one” and “we weighed the door” are different answers with different consequences.

The door got heavier and nobody told the springs

High risk — call a technician

The one people never suspect, because the change happened deliberately and felt like an improvement at the time.

Anything added to the door adds weight the counterbalance wasn't sized for. An insulation kit — panels of rigid foam or batting fitted into the sections — is the big one, and it's popular here for obvious reasons. Replacement sections that are heavier than the originals. Window inserts fitted after the fact. Even years of repainting adds a surprising amount across a large steel surface.

None of those break anything. They just move the door's end of the see-saw, and unless somebody re-matched the springs at the same time, the door has been under-sprung ever since. It'll be heavy by hand, the opener will work harder, and the springs will spend their rated cycles faster than they should.

The giveaway is timing. If the door started feeling different within a few months of any work being done to it, that's the connection.

How you can tell: Insulation, new panels, glass or repeated repainting in the door's history, followed by the door feeling heavier and the opener sounding busier.

Where to stop: If you're planning to insulate a door, raise the counterbalance question first rather than afterward. Re-sizing springs at the same time is a much smaller job than discovering the problem two years later with a set of prematurely worn springs. Tell us what changed about the door when you book the garage door spring repair, and the sizing gets done once.

Friction — the part you can actually do something about

Hands-on — moderate risk

Drag isn't the same as weight, but it feels identical in your hands, and on plenty of doors it's a meaningful share of the effort.

Rollers that have gone dry skid in the track instead of rolling. Bearings that have seized turn a rolling contact into a sliding one. Hinges that have never been touched bind at the pivot. Grit packed into the base of the vertical tracks adds resistance at exactly the point where the door starts moving. On a door that has never been maintained, all of that stacks up.

Worth being honest about the limits: cleaning and lubricating won't fix an under-sprung door and it won't rescue fatigued springs. What it does is remove the friction component, which sometimes turns a door that felt alarming into one that feels merely heavy — and which makes the balance test that follows a much more honest measurement.

Lubrication is covered in detail on its own page. The short version is silicone or white lithium grease on rollers, hinges and bearings, and never the classic blue-can penetrant, which thins out, attracts dust and can strip the grease already there.

How you can tell: The door is rough and noisy as well as heavy, moves unevenly, and has hardware that looks dry, dusty and gray.

The fix

Close the door and unplug the opener before you start, so nothing can move while you're working alongside it.
Look along both vertical tracks with a flashlight for grit packed into the bottoms, and sweep it out.
Wipe the track running surfaces clean rather than greasing them — a track is a running surface, not a bearing.
Look at each roller as the door moves and note any that skid rather than turn, or that wobble in their stems.
Lubricate rollers, hinges and bearings with silicone or white lithium grease per the lubrication page.
Leave the springs, the cables, the drums and the bottom brackets entirely alone — none of those are maintenance items.
Re-run the balance test afterward. Now you're measuring the counterbalance rather than the counterbalance plus friction.

You’ll know it’s right when: The door runs quieter and more smoothly, nothing catches at any point in the travel, and you have a clean balance measurement to work from.

Where to stop: If a roller is visibly worn, a hinge is cracked, or a stem is bent, stop and have it replaced rather than lubricated. And if the door is still heavy once the friction is gone, that's the answer — it's the springs, and no amount of maintenance addresses that.

The door is binding in the opening

High risk — call a technician

Different from general friction, because it's localized and geometric rather than spread across the hardware.

A track that isn't plumb, a bracket that has worked loose and shifted, a door installed slightly out of square, or an opening that has moved — all of these squeeze the door against something on part of its travel. The characteristic symptom is resistance that appears at a specific height rather than everywhere, and a door that's noticeably harder in one direction than the other.

Around here, the opening moving is a genuine possibility rather than an exotic one. Garage slabs settle, and a settled slab or a shifted jamb changes the relationship between the door and the tracks that were installed to the original geometry. The door then rubs where it never used to.

What makes this one worth separating from friction is that lubricating it doesn't help and can disguise it. The door needs realigning, not slicking up.

How you can tell: Resistance concentrated at a particular point in the travel, often with a rubbing or scraping noise, and sometimes with bright wear marks on the track edge or the jamb.

Where to stop: Don't try to bend a track back into line. Track alignment is what keeps the door in the opening, and correcting it by eye is a reliable way to turn a rubbing door into a door that leaves its rails.

A cable or drum problem making one side heavy

High risk — call a technician

If the effort isn't even across the door — if one side comes up ahead of the other, or the door twists as it rises — this isn't a balance problem at all.

What that describes is one side of the door having lost some or all of its support: a cable off its drum, a drum that has slipped on the shaft, or a cable that has parted. The door then rises unevenly, the rollers get pushed into the track at an angle, and it takes much more effort because you're fighting the geometry as well as the weight.

Worth stating clearly, because it comes up constantly: a broken torsion spring does not cause this. Both springs on a two-spring door sit on the same shaft and work as one counterbalance, so a spring failure makes the door uniformly heavy rather than lopsided. Unevenness means cables and drums, and that's covered on its own pages.

How you can tell: One side lifts before the other. The door looks twisted in the opening. Sometimes a visibly slack cable, or a cable sitting outside its drum groove.

Where to stop: Stop operating the door entirely. A door cycling with one corner unsupported is the stage immediately before a door off its track, and that's a considerably longer repair than the one you currently have.

Extension springs that have permanently stretched

High risk — call a technician

Doors with extension springs — the long ones running back alongside the horizontal tracks — get heavy in their own particular way.

Rather than fatiguing to a break, an extension spring commonly takes a permanent set. It stretches slightly and never returns to its original free length, so it produces less pull than it used to. The door gets heavier by degrees, and the springs look longer and lazier than they did, sagging noticeably when the door is closed.

What makes this confusing is that nothing is broken. People look at the springs, see them intact, and conclude the springs can't be the problem. They can be, and on an older extension-spring door they usually are — the practical end of the spring's life arrives well before it ever parts.

The other thing to check on any extension setup is whether a safety containment cable runs through the middle of each spring. It has nothing to do with the weight and everything to do with what happens on the last day.

How you can tell: Springs alongside the upper tracks rather than a shaft above the opening, sagging visibly with the door down, on a door that has been getting steadily heavier for years.

Where to stop: Intact isn't the same as working. If the door is heavy and the extension springs look tired, they probably are — and the assessment is a measurement rather than a judgment by eye.

What you’ll need if you’re doing this yourself

A flashlight — checking the coil, the cables and the track bottoms all depend on it, and none of them are lit
Your own two hands — the balance test is the measurement this whole page turns on, and it needs nothing else
Silicone spray or white lithium grease — for the friction component only — never the classic blue-can penetrant, which strips lubricant rather than adding it
A broom — grit packed into the base of the vertical tracks is a genuine share of the resistance on plenty of Valley doors

Things not to do — and why

× Don't turn up the opener's force setting to make it lift more easily

The door still weighs what it weighs. All you'd change is how hard the opener is willing to push before deciding it has hit something — which is the mechanism that makes it reverse on an obstruction.

× Don't adjust the spring tension yourself

Winding a torsion spring means putting a controlled amount of stored energy into a bar you're holding, with your hands next to the winding cones. The consequence of losing control of it isn't a bruise.

× Don't keep using a door that's meaningfully heavy

Every cycle, the opener is making up the shortfall, and it's a positioning device rather than a lifting one. The nylon drive gear is the sacrificial part, and this is the load path that finds it.

× Don't lubricate the springs or cables to make things move better

Neither is a friction surface in a way that helps, and putting a solvent-based spray near a cable washes out what protects it. In this valley you'd also be adding a dust magnet to the parts you least want grinding.

× Don't insulate a door without asking about the counterbalance

An insulation kit adds real weight to the panels, and springs that weren't re-matched to it are under-sized from the day it goes in. It's a small conversation before and an expensive discovery afterward.

× Don't assume smooth means balanced

Friction can hold a door in position that the springs no longer support, so a stiff door can pass the hold-position test for entirely the wrong reason. The measurement is only honest once the hardware is running freely.

× Don't try to bend a rubbing track back into line

The track is what keeps the door in the opening. Approximate alignment produces a door that binds somewhere else, and eventually one that comes off its rails.

× Don't ignore a door that's heavier on one side

That isn't a balance problem at all. It means one corner has lost support, which is a cable or drum issue and considerably more urgent than a heavy door.

× Don't grab the door between the sections to pull it down

It's the most natural handhold on a door and it's the one DASMA names as a hazard — the section-to-section joint “is not a suitable gripping point” and gripping there “could result in serious injury.” The sections fold against each other as the door moves. Use the handles: four are required on a residential sectional door, two inside and two outside, within eight inches of the bottom edge of the bottom section.

What makes doors here get heavy sooner

Three things about Valley garages push doors toward this, and one of them is something homeowners here do on purpose.

That one is insulation. Garages across Mesa, Chandler and Gilbert get used as workshops, gyms and storage that people actually want to walk into in July, so retrofitting insulation into the door panels is a popular and sensible upgrade. It also adds meaningful weight, and if nobody re-matched the springs, the door has been under-sprung ever since.

Insulation retrofits add weight nobody accounts for — a genuinely good idea in this climate that becomes a spring problem when the counterbalance isn't re-sized at the same time.
Hours parked open cost the springs — DASMA's spring cycle-life sheet points at doors left open for long stretches, not at ambient heat, and recommends keeping the door closed where possible in extreme-heat climates. A garage that stands open every afternoon is running that exposure, and a spring losing lift is the leading cause of a door that got heavy gradually.
Monsoon dust works into roller bearings — fine silt gets into the races, turns rolling into sliding, and adds drag that feels exactly like weight.
The bottom seal grabs hot concrete — a seal softened by heat can stick to a slab that's been in the sun all day, which is why some doors are hard for the first few inches in the afternoon and normal in the morning.
Grit collects at the base of the vertical tracks — right where the door starts moving, and it's the last place anybody looks.

Keeping a door light

The theme here is measuring rather than waiting. A door that has become heavy took a long time to get there, and the whole opportunity is in noticing partway.

Run the balance test twice a year — that cadence is ours, not a standard. DASMA publishes monthly homeowner safety checks and an annual technician visit; we've found twice a year is what people will actually do for balance specifically. Five minutes, and it turns “does this feel heavier?” into an answer. The full method is on our balance-test page.
Lubricate rollers, hinges and bearings twice a year with silicone or white lithium grease, so friction never becomes a share of the effort.
Sweep out the base of the vertical tracks after dust storms — it's the cheapest thing on this list and it addresses the resistance right where the lift starts.
Re-size the springs any time the door gains weight — insulation, new sections, added glass, repeated repainting. Raise it before the work rather than after.
Listen to the opener occasionally — a motor that sounds like it's working harder than it used to is reporting a counterbalance that has fallen behind.
Note when the door stops holding position — a door that used to stay where you left it and now sinks has changed measurably, and that's the moment to act.
Don't let one heavy side get normalized — unevenness is a cable or drum fault and it belongs in a different, more urgent category than general heaviness.

Where a heavy door sits in the sequence

This is the second stage of the most common failure chain on a residential door, and each step genuinely produces the next.

A spring breaks, or loses enough tension to stop counterbalancing the door

→

The door's weight shows up in your hands and in the opener (you are here)

→

Forcing a heavy door lifts one side ahead of the other and it rises crooked

→

The slack side unspools and a cable leaves its drum

→

With one corner unsupported, the door jumps the track

This is the stage where the whole sequence is still cheap, and it's the last one that gives you months rather than cycles to act.

How we diagnose a heavy door

The whole visit is built around separating weight from friction, because they feel identical and they have completely different answers.

What we do on a visit for this

Disconnect the opener and test the door by hand through its whole travel, noting where it holds and where it drifts
Weigh or calculate the door as it stands today, including anything added since it was installed
Measure the springs and work out what lift they're actually producing against what the door needs
Separate the friction component by checking rollers, hinges and bearings independently
Check both vertical tracks for plumb and both horizontal tracks for level
Look for binding points by moving the door slowly and feeling where resistance appears
Check cables and drums for even take-up, since unevenness masquerades as heaviness
Check the opener's drive gear and travel for damage from carrying the shortfall
Re-balance by hand and run the safety reversal test the way UL 325 requires

You'll get a written quote before any work starts. If the door turns out to be heavy from drag rather than springs, a garage door tune-up may be all it needs.

The service that fixes this

When you want it handled rather than diagnosed, this is the page for it: garage door spring repair. Depending on what you find, garage door tune-up may be the closer fit.

What determines the answer here

A heavy door is a symptom rather than a repair, so the range is wide — and the cheap end of it is genuinely cheap.

Whether it's friction or counterbalance Rollers, lubrication and clearing track grit are modest work. Springs are parts and a controlled procedure. Establishing which you have is the first thing we do.
Whether the springs are fatigued or simply mis-matched A door that has gained weight needs a different spring rather than a fresher one, and getting that wrong repeats the problem.
Cycle rating on the replacement Heavier wire costs more up front and buys years. On a door used as a household's main entrance that trade usually pays.
Roller and hinge condition Worn rollers are inexpensive parts, and replacing them removes drag permanently rather than temporarily.
Track alignment A door binding because a track has moved needs realigning, which is labor rather than parts but isn't a five-minute item.
What the opener has absorbed A motor that has been covering a shortfall for a year sometimes needs attention too, and that's cheaper to find now than in the middle of a repair.

Almost all the variation in a garage door spring repair comes from what the door weighs and what else moved when the counterbalance gave up. You'll get a written quote before any work starts. If you're due anyway, our full tune-up is $39.99 — same price in every city we serve.

Where this information comes from

DASMA Technical Data Sheet #167 — Residential Sectional Garage Door and Electric Operator Checklist — source of the two balance questions this page leads with — does the door move freely and not faster than the force applied, and does it hold three to four feet above the floor
DASMA Technical Data Sheet #165 — Manual Operation of a Garage Door — the section-joint warning and the ANSI/DASMA 116 requirement for four gripping points within eight inches of the bottom edge of the bottom section
DASMA Technical Data Sheet #176 — Adding Weight To a Garage Door Assembly — the 90-to-over-500-pound weight range, and why an insulation retrofit changes what the springs have to carry
DASMA Technical Data Sheet #190 — Factors Affecting Spring Cycle Life — handling, installation and usage factors behind a spring losing lift. It publishes no cycle-count rating
UL 325 — safety standard for residential garage door operators — the reversal requirement that force settings are part of, and why turning force up to lift a heavy door is the wrong move
