Why is my garage door so heavy to lift by hand?
Because the springs, not your arms, are supposed to carry the weight. A balanced door lifts with about 10 to 15 pounds of effort even though a double steel door weighs 200 to 350 pounds. If yours feels like dead weight, a torsion spring has broken or lost tension, and the spring system is what needs service, not the door.
Your Door Weighs More Than You Think
Homeowners are usually shocked by real door weights. Rough numbers for common OKC configurations:
| Door type | Typical weight |
|---|---|
| Single (9x7) non-insulated steel | 75-100 lbs |
| Single (9x7) insulated steel | 100-135 lbs |
| Double (16x7) non-insulated steel | 150-200 lbs |
| Double (16x7) insulated steel | 200-300 lbs |
| Double wood or carriage-style | 300-450 lbs |
The torsion spring above the door (or extension springs beside the tracks on older setups) stores enough energy to offset nearly all of that. When the counterbalance is right, the net lifting effort is about what a bag of dog food weighs. So a door that suddenly requires a deadlift has not gained weight; it has lost its counterweight.
Broken, Worn, or Wrong: The Three Spring Failures
Broken is the obvious one. A torsion spring break is usually loud, like a firecracker in the garage, and leaves a visible gap of an inch or two in the coil above the door. From that moment the opener or your back carries everything, which is why openers frequently strip their gears in the days after a spring breaks and nobody noticed the bang.
Worn is sneakier. Springs are rated in cycles, commonly 10,000, which sounds like forever but works out to seven to ten years for a family cycling the door four times a day. A tired spring has not snapped; it has just relaxed, so the door gets gradually heavier each season until someone finally pulls the release cord during a power outage and discovers the truth.
Wrong-sized springs turn up more than they should, usually after a previous owner or a bargain outfit fitted whatever was on the truck. If the door has felt heavy since the day you bought the house, this is a live possibility. It also explains doors that refuse to stay open on their own.
What to Do, and What Never to Do
Confirm with the balance test: door closed, release cord pulled, lift to waist height, let go carefully. Sinking equals weak; unliftable equals broken. Then stop operating the door, including with the opener, because forcing an unbalanced door destroys gears and stresses cables.
The never-do is winding or replacing torsion springs yourself. The stored energy in a wound spring can spin a winding bar through a wrist or worse, and it is the one garage door job even handy people should skip. Professional spring replacement is priced by spring size and cycle rating, takes under 90 minutes, and includes rebalancing and a safety check of cables and bearings. We stock spring sizes for CHI, DoorLink, Haas, Mid-America, and virtually every door in the metro, so it is almost always a single same-day visit.

What causes a garage door to jerk or shudder while opening?+
Jerky travel usually comes from flat-spotted rollers, a slack chain, loose hinges, or a track knocked out of alignment. Each cause has a distinct rhythm and sound that narrows the diagnosis quickly. Read the full answer →
Can I still use my garage door if the opener is broken?+
Yes. Pull the emergency release cord and operate the door manually as long as it is balanced. Just remember the door no longer locks itself, so use the manual slide lock or a bolt through the track overnight. Read the full answer →
Can a dented garage door panel be fixed without replacing it?+
Shallow cosmetic dents can often be improved or left alone, and a single damaged panel can be replaced if the design is still manufactured. Widespread hail damage usually justifies an insurance claim and full replacement instead. Read the full answer →
