Our Garage Door Parts Services in Olmos Park

Torsion Spring Replacement

Original torsion springs in Olmos Park’s 1930s-1950s garages cycled past their 10,000-cycle rating decades ago. San Antonio’s weeks of 100°F+ summer heat fatigues the metal further, and hard freezes like Winter Storm Uri in February 2021 snapped springs across the city overnight. Olmos Park’s older assemblies were especially vulnerable. We carry high-cycle springs rated for 25,000 cycles, sized for non-standard headers and older track configurations. A typical spring repair in Olmos Park runs $180-$340, quoted upfront before we start.

Extension Spring Systems

Some of Olmos Park’s smaller detached garages and carriage houses still run extension springs along the horizontal tracks. These systems are increasingly rare, and parts availability has narrowed as manufacturers standardized on torsion setups. We maintain stock for legacy extension spring hardware and can convert to torsion where the door weight and headroom allow. If your extension spring broke on an original door near Olmos Park Boulevard or Contour Drive, we can match what you have or recommend a clean upgrade path.

Cables & Drums

Cable failures often follow spring breaks. When a torsion spring snaps, the sudden release of tension lets the cable jump the drum or fray against misaligned hardware. We were called to a 1940s Spanish Colonial Revival home on Olmos Park Avenue where the original one-piece door had a snapped torsion spring and cables that had jumped the drums. Because the opening was only 8 ft 6 in wide with old wood framing, we could not just drop in a standard sectional door. We used a high-cycle torsion spring rated for 25,000 cycles, replaced the cables and drums, and realigned the original track so the door balanced properly while the homeowner waited on a custom carriage-house door order that matched the period architecture. Cable repair in Olmos Park typically costs $130-$250.

Rollers & Hinges

Steel rollers on original track hardware grind and seize after eighty-plus years of use. Nylon rollers are quieter but may not fit older angle-iron track without modification. We carry both standard and slim-profile rollers for legacy track, along with heavy-duty hinges that match the hole spacing on older sectional doors. Roller replacement in Olmos Park generally runs $110-$220.

Weatherstripping & Bottom Seal

Olmos Park’s sustained summer heat degrades rubber bottom seals into brittle, cracked strips that let in dust, pests, and conditioned-air leaks. Older wood doors need vinyl or brush-style seals that compress against uneven surfaces without tearing. For steel or faux-wood doors, we use thermoplastic elastomer seals that resist UV breakdown longer than standard rubber. This is routine maintenance that prevents bigger problems. Track realignment, often needed alongside seal replacement on shifted older frames, runs $120-$240 in Olmos Park.

Trusted Brands We Service in Olmos Park

We are factory-familiar with all major brands and maintain parts stock for LiftMaster, Chamberlain, and Genie openers commonly found in Olmos Park’s legacy installations. Many homes near McCullough Avenue still run older chain-drive Craftsman units or early belt-drive Genie systems that other companies decline to service. We carry drive gears, circuit boards, safety sensors, and rail sections for these units, and we can source discontinued parts through our supplier network when a direct replacement is no longer manufactured. For the door itself, we work with Clopay and other manufacturers who offer custom sizing for Olmos Park’s non-standard openings. Our trucks arrive stocked so most jobs are completed in a single visit, no waiting on parts, no second trip.

Common Garage Door Parts Problems We See in Olmos Park Homes

• Original torsion springs from the 1930s-1950s that have cycled far past their 10,000-cycle rating and snap during San Antonio’s 100°F+ summers or hard freezes like Winter Storm Uri. These springs were not designed for modern usage patterns, and their age makes them unpredictable.
• Legacy one-piece or early sectional doors with original track hardware and non-standard 8-9 ft openings - replacement parts often require custom sizing or header modification rather than off-the-shelf components. A standard 16×7 door simply will not fit.
• Brittle rubber bottom seals and weatherstripping on old wood doors that crack and crumble, letting in heat and pests while the door loses its seal against the frame. The summer sun bakes these components until they turn to dust.
• Steel panels of later doors that warp and expand in sustained summer heat, stressing hinges and track hardware that was not designed for the thermal movement. This creates binding and premature wear on rollers and cables.
