How to fix or replace a garage door

Springs, cables, rollers, hinges, and openers each have very different price points and labor profiles. A snapped torsion spring (the most common call) is a 45-minute job once the pro is on site. A bent track from someone backing into the door is a 2-hour job. A failed opener logic board is sometimes a $40 part swap, sometimes a full opener replacement because parts are no longer manufactured for the unit. Tell the pro what you observed — door will not move, door moves crooked, motor hums but no movement, remote dead but wall button works — so they can bring the right parts.

A non-insulated 25-gauge steel door is the builder-grade default and the cheapest replacement option. Insulated doors come in two- or three-layer construction with polystyrene (R-6 to R-12) or polyurethane foam (R-13 to R-20). For attached garages or any garage with conditioned space above it, R-13+ polyurethane is worth the upcharge — it stops the garage from acting as a thermal sink and the foam structurally stiffens the section so it does not flex in wind or hail. For detached unheated garages, R-value is mostly noise reduction and durability, not energy.

Single-car doors (8x7 or 9x7) are roughly 60% of the cost of a double-car (16x7). Tall doors for trucks or RV bays (8-ft or 10-ft tall) move into custom territory and need heavier springs, longer torsion shafts, and sometimes a high-lift conversion. Two single doors usually costs less than one double because the spring math and reinforcement is simpler — but a single 16x7 looks cleaner from the curb and is what most builders specify today.

Chain-drive openers are the cheapest and noisiest — fine for a detached garage. Belt-drive (rubber-reinforced) is the quiet upgrade and is what most homeowners want under a bedroom. Direct-drive (Sommer) and jackshaft/wall-mount (Liftmaster 8500) are premium options: jackshafts mount on the wall next to the door instead of overhead, freeing ceiling space for storage or high-lift conversions. Horsepower matches door weight: 1/2 HP for standard 8-ft doors, 3/4 HP for heavy insulated or wood doors, 1+ HP for oversized or carriage doors.

Liftmaster and Chamberlain openers from 2020+ ship with myQ Wi-Fi standard — there is no upcharge for the smart functionality if you buy the current model. Genie has Aladdin Connect. HomeKit support requires an additional bridge ($50–100) or a third-party hub. The useful feature is not the app — it is the close-from-anywhere capability and integration with security systems and Tesla/Rivian "auto-open on arrival". Battery backup for openers became required in California in 2019 and is standard on most current Liftmaster/Chamberlain models, adds about $50–80 to the install price elsewhere.

Most installers include haul-away in the install price; some itemize it ($75–150). If the existing jambs are rotted, weather stripping is shredded, or the header is sagging, those need addressed before the new door goes in — otherwise you have a $3,000 door against a $200 frame problem. Ask whether jamb replacement, new vinyl weatherseal, and a new bottom astragal are included or quoted separately.

Clopay, Amarr, CHI, and Wayne Dalton are the major US manufacturers and parts are widely stocked by any pro who works in your area. Sears Craftsman openers and some private-label big-box doors had decade-long parts droughts that left owners with $2,000+ doors that could not be serviced. If you are quoted an unfamiliar brand, ask which national distributor stocks the parts — Doormaster, Service Spring, and IDC are the three big ones. If the answer is vague, ask for a different brand.
