Broken spring, dead opener, or a door that rusted through near the beach — what each actually costs.
Last updated
Torsion spring replacement — the most common garage door failure — runs $200–$450 for a single spring and $300–$600 for a pair, and you should always replace both at once since they wear together. A new opener installed costs $350–$800, and a full door replacement runs $1,200–$2,500 for a standard steel two-car door or $3,500–$8,000 for insulated custom or wood. Salt air near the coast rusts hardware, springs, and steel panel bottoms years earlier than inland, so ask for galvanized springs and stainless hardware if you are in Point Loma, OB, PB, or Imperial Beach. The scam to know about: an ad promising a $29 or $49 service call, followed by a technician who declares the whole system unsafe and quotes $1,500. Get a phone quote for the specific part, ask for the price to replace a pair of springs before the truck rolls, and confirm any structural door replacement is done by a licensed contractor.
| Job | Typical cost | Notes |
|---|---|---|
| Service call / diagnostic | $50–$120 | Beware $29 loss-leader ads |
| Torsion spring, single | $200–$450 | Replace in pairs |
| Torsion springs, pair | $300–$600 | 10,000–20,000 cycle life |
| Cable replacement | $150–$300 | Often paired with spring failure |
| Roller replacement (set) | $150–$300 | Nylon rollers are much quieter |
| Track realignment | $150–$300 | After a bump or an off-track door |
| Opener replacement, chain drive | $350–$550 | Loud but durable |
| Opener, belt drive with Wi-Fi | $500–$800 | Quiet; worth it under a bedroom |
| Panel replacement (one) | $250–$800 | Matching an older door is often impossible |
| New steel door, 2-car, installed | $1,200–$2,500 | Standard non-insulated to mid-grade |
| Insulated / custom / wood door | $3,500–$8,000 | Carriage-house and wood clad |
| Tune-up and lubrication | $80–$150 | Annual, doubles hardware life |
That is a broken torsion spring, and it is the single most common failure. Do not try to force the door open with the opener — you will burn out the motor. This is not a DIY repair; loaded springs cause serious injuries.
Usually a stripped drive gear or a disconnected trolley. Gear kits are cheap; if the opener is over 15 years old, replacement makes more sense.
Misaligned or dirty photo-eye safety sensors near the floor. Wipe the lenses and realign until both LEDs are steady. This one is genuinely DIY.
Worn rollers or dry bearings. A tune-up with nylon roller replacement transforms how a door sounds.
Stop using it. A cable came off a drum or the door was bumped. Forcing it bends the track and turns a $200 repair into a $900 one.
Classic beach-adjacent failure. If the steel is perforated, panel replacement on an older door rarely matches and full replacement is usually the better spend.
Within a mile or two of the water, springs, hinges, and fasteners corrode fast. Specify galvanized springs and stainless or coated hardware and rinse the door twice a year.
Inland, an insulated door with an R-value in the 9–18 range makes a garage gym or workshop usable in September and helps if the garage shares a wall with living space.
Converting a garage to living space means the door opening becomes a wall or a window assembly, which is a permitted change. Coordinate with the ADU builder rather than the garage door company.
Many HOAs and some coastal overlay zones restrict door style and color. Check before ordering a custom door — lead times run four to eight weeks and they are non-returnable.
California requires battery backup on residential garage door openers sold and installed in the state, so you can get out during a power outage or PSPS event. Confirm the model complies.
Smart openers are convenient but never leave the remote clipped to the visor of a car parked outside; that plus your registration is a house key.
The classic setup. The technician arrives, condemns the springs, cables, rollers, and drums, and quotes four figures. Legitimate companies quote realistic diagnostic fees.
Ask what a pair of torsion springs costs installed before dispatching anyone. If they refuse to give any range, call someone else.
Lead-generation outfits list dozens of fake local addresses. Look for a real San Diego County location and years in business.
Straight repairs are often handled by service technicians, but full door and opener installation over $500 requires a licensed contractor (commonly D-28 garage door). Verify at cslb.ca.gov.
A broken spring is inconvenient, not an emergency. Getting a second quote the next morning routinely saves several hundred dollars.
Springs should carry a cycle-rated warranty; installations typically a year on labor. Get it on the invoice, not verbally.
About $200–$450 for one torsion spring installed and $300–$600 for a pair. Always replace both — they have the same cycle life, so the second one usually fails within months of the first.
A standard steel two-car door installed runs $1,200–$2,500. Insulated, carriage-house, or wood-clad custom doors run $3,500–$8,000, with four to eight week lead times on custom orders.
Almost always the photo-eye safety sensors near the floor are dirty or knocked out of alignment. Clean the lenses and adjust until both indicator lights are solid. It is one of the few garage door fixes that is safely DIY.
You should not. Torsion springs store enormous energy and cause severe injuries when released improperly. This is the one garage door job where paying a professional is unambiguously the right call.
Yes. Beach-adjacent homes see rusted springs, hinges, fasteners, and perforated bottom panels years earlier than inland homes. Specify galvanized springs and coated or stainless hardware, and rinse the door with fresh water a couple of times a year.
Yes. State law requires battery backup on residential garage door openers so you can open the door during a power outage, which matters during Public Safety Power Shutoffs.
