We’ve been fixing garage doors since 1984. That’s 42 years of working on the homes in this part of Bexar County, from the tree-lined streets near Alamo Heights High School to the older ranch-style houses off Broadway. We know the local conditions: the humidity that swells wooden doors in summer, the hard water that corrodes hardware, and the way Alamo Heights’ clay soil shifts and settles, throwing tracks out of alignment over time. Carl Dutton has led this shop from the beginning, and our technicians are trained journeymen, not seasonal hires. When we quote a price, it’s the price. No surprises on the bill.
What Our Garage Door Repair Service Includes
Panel Replacement
A damaged panel does more than look bad. It weakens the entire door structure and can throw off the balance that keeps your opener from burning out. In Alamo Heights, we replace panels on everything from original mid-century doors near Terrell Hills to newer Clopay carriage-house styles in Olmos Park. We match the gauge, insulation rating, and finish so the repair doesn’t stick out. Most panel replacements run $250-$500 and are done in one trip.

Spring Repair
The spring is what the company is named for, and it’s still the repair we handle most often. A broken torsion or extension spring means your 150- to 300-pound door is dead weight, and trying to lift it manually risks injury or worse. We stock springs for all common door weights and heights, and we match the cycle rating to how often you use the door. Spring repair in Alamo Heights runs $180-$340, and we always replace both springs on a paired system so they wear evenly. This is not a do-it-yourself job: the stored energy in a wound torsion spring can cause serious injury without proper tools and training.

Cable Repair
Cables do the lifting that springs make possible. When they fray, unwind from the drum, or snap entirely, your door can drop unevenly or jam completely. We see cable damage often on older Alamo Heights homes where original hardware has never been serviced. Our trucks carry galvanized and stainless steel cables in multiple lengths, and we inspect the drums and bottom brackets while we’re at it. Cable repair typically costs $130-$250.

Track Realignment
Bent, loose, or misaligned tracks make a door bind, shudder, or refuse to close. In Alamo Heights, foundation settling from our expansive clay soil is a common cause. We don’t just hammer the track straight; we check plumb and level, verify the bracket anchoring, and lubricate the full run. Track realignment runs $120-$240, and we warranty the work under our 90-Day Done Right Promise.

Roller Replacement
Worn rollers make a door noisy, jerky, and hard on the opener. Steel rollers rust. Nylon rollers crack. We stock both, plus sealed-bearing upgrades that stay quiet longer. On many Alamo Heights homes built in the 1960s and 70s, we’ve replaced original rollers that had simply worn down to nothing after fifty years of use. Roller replacement costs $110-$220 for a standard door.

Sensor Calibration
Photo-eye sensors are required by federal safety law, and when they’re misaligned, your door won’t close or reverses for no reason. Sun glare, landscaping shifts, and accidental bumps are the usual culprits in Alamo Heights. We clean, realign, and test the full safety system, including force settings and sensor calibration, so the door responds correctly to obstructions. This is often bundled with a tune-up or done as a standalone call.

Brands We Service for Garage Door Repair
We’ve worked on hundreds of LiftMaster and Chamberlain openers in Alamo Heights and the surrounding neighborhoods. We know their gear assemblies, their logic boards, and the specific failure patterns of each model line. That familiarity means faster diagnosis and repairs that hold up. We carry OEM and equivalent parts for both brands on every truck.
Genie screw-drive and belt-drive units are common in the area too, and we’ve rebuilt or replaced more than we can count. Whether you have Genie, LiftMaster, Chamberlain, or any other make, we can help. Our technicians are factory-familiar with all major brands, and if a part is still manufactured, we’ll have it or source it without leaving you waiting.
Signs You Need Garage Door Repair Right Now
- The door won’t open or close fully. This usually means a broken spring, stripped gear in the opener, or a safety sensor issue. A door stuck open leaves your home exposed; one stuck closed traps your vehicles inside. Either way, it’s worth a call to get it diagnosed.
- You hear loud grinding, popping, or squealing. These sounds point to metal-on-metal contact, worn rollers, or a failing opener gear. Ignoring them turns a $150 repair into a $600 replacement. In Alamo Heights, we hear this complaint most often from homes with original hardware that’s never been serviced.
- The door hangs crooked or one side moves faster than the other. This signals a cable problem or a spring that’s lost tension on one side. Operating the door in this condition risks the cable snapping or the door jumping the track entirely.
- There’s a visible gap in the torsion spring above the door. A broken spring is unmistakable once you know what to look for: a two-inch separation in the coil. Do not attempt to open the door. The full weight is unsupported, and the remaining spring tension makes manual lifting dangerous.
- The opener runs but the door doesn’t move. This often means the trolley has disconnected or the main drive gear is stripped. It’s a straightforward repair for a trained technician, but continuing to run the opener will destroy the motor.

- 3
You get the flat price upfront. Before any wrench turns, we state the total cost in writing. No hourly rates, no trip charges hidden in the fine print, no pressure to add work you don’t need. You approve it, or you don’t pay a thing.

- 5
We test, clean up, and guarantee the work. The door is cycled multiple times, safety systems are verified, and the work area is left as we found it. You receive a written invoice with the 90-Day Done Right Promise stated clearly: if it’s not right, we come back at no charge.
How Much Does Garage Door Repair Cost in Alamo Heights?
Most garage door repairs in Alamo Heights fall between $150 and $600, with the exact figure depending on what’s broken and what it takes to fix it right. A typical spring repair runs $180-$340. Cable work is usually $130-$250. Track realignment costs $120-$240. Panel replacement ranges from $250-$500 depending on the material and whether insulation matching is needed. Roller replacement is generally $110-$220. If the opener itself needs attention, repair runs $120-$320; full replacement is $250-$550 for the unit plus installation.
Several factors move the price within these ranges. Door size matters: a standard 16-foot two-car door needs heavier springs and longer cables than a single-car unit. Material affects panel costs; insulated steel is priced differently than aluminum or composite. Accessibility counts too. If your garage is packed with storage or the opener is mounted in a tight attic space, the labor time increases modestly.
The best way to avoid overpaying is to get the full scope in writing before work starts. We see estimates from other companies that quote a low spring price but add separate charges for the winding cone, the center bearing, or a “service fee.” Our price is flat and includes everything needed to do the job correctly. The free estimate we provide covers diagnosis, the written quote, and our recommendation with no obligation.
Current standing offers: $50 off any repair over $250, a free second opinion on any written estimate you’ve received, and a permanent 5% discount for seniors and veterans. The $89 seasonal tune-up is also available and can catch problems before they become emergency calls.
