Call (210) 972-1317 and a live person will answer, day or night.
Somerset’s housing tells a story. You’ll find original mid-century ranch homes on large lots, older manufactured homes with basic single-bay steel doors, and newer subdivisions creeping south from San Antonio along US-181 and TX-16. Many of those older doors are running on springs and openers installed twenty or thirty years ago. The parts are still available. The question is whether repair or replacement is the smarter money.
We dispatch to Somerset from our San Antonio office, and our crews know the local roads well enough to reach most Somerset addresses quickly. More importantly, they know the local soil. Somerset sits on expansive black clay, Vertisol, that swells when wet and shrinks when dry. That movement racks door frames, throws tracks out of alignment, and stresses springs in ways that look like hardware failure but aren’t. A technician who doesn’t understand that clay will sell you parts you don’t need.

Our Garage Door Parts Services in Somerset
Torsion Spring Replacement
Torsion springs carry the full weight of your door. When they snap, the door won’t lift, and continuing to run the opener will burn out the motor. In Somerset, we see a specific pattern: original low-cycle springs on 1990s and older doors reaching end-of-life mid-cycle, often after a dry-to-wet clay shift racks the frame and unloads one spring unevenly. The homeowner hears a loud bang from the garage and finds the door dead.
A typical torsion spring repair in Somerset runs $180-$340. We install high-cycle springs rated for more open-close cycles than the originals, which matters on a door that sees heavy use. We also inspect the drums and cables while we’re in there, because a snapped spring often throws related components out of spec.

Extension Spring Service
Extension springs run along the horizontal tracks and stretch to assist lifting. They’re more common on lighter doors and some older Somerset manufactured home setups. These springs are under high tension and can be dangerous to handle without training. We don’t recommend homeowner inspection beyond a visual check for gaps or rust.
If your Somerset door has extension springs showing wear, we’ll replace them with properly matched pairs and install safety cables if they’re missing. Uneven extension springs are a common cause of crooked door travel, which on Somerset’s shifting clay foundations can be mistaken for track damage.

Cables & Drums
Cables lift the door. Drums manage cable wrap at the top of the shaft. When cables fray or drums crack, the door can drop unevenly or jam entirely. In Somerset, we frequently find cables gone slack after clay movement shifts the door frame and changes cable tension. The homeowner thinks the cable broke; often it just needs re-tensioning and the track needs realignment.
Cable repair in Somerset typically costs $130-$250. We carry multiple cable gauges and drum sizes for the variety of door weights we encounter here, from lightweight manufactured home units to heavy insulated sectional doors in newer subdivisions.

Rollers & Hinges
Rollers guide the door in the track. Hinges flex thousands of times per year. On older Somerset doors, we see steel rollers worn to flats and hinges with elongated bolt holes from decades of vibration. Nylon rollers run quieter and don’t require lubrication, but the right replacement depends on your track size and door weight.
Roller replacement in Somerset runs $110-$220. We inspect every hinge and roller during the job, because replacing one worn roller while leaving its neighbor to fail in six months is not a square deal.

Weatherstripping & Bottom Seal
Somerset’s weather seal takes a beating. The February 2021 ice storm seized and cracked seals that had never seen freezing conditions. Then the South Texas summer bakes them brittle with sustained 100°F+ heat. By fall, the seal is leaking clay dust, moisture, and insects into the track.
We replace bottom seal and perimeter weatherstripping with materials rated for this temperature swing. Proper seal also reduces the debris that accelerates roller and track wear. On Somerset’s shifting foundations, a flexible seal compensates for minor frame movement that a rigid seal would tear against.

The price is stated before we start.
Common Garage Door Parts Problems We See in Somerset Homes
- Clay-racked frames mimicking hardware failure. After dry summers and heavy fall storms, Somerset’s expansive black clay shifts enough to throw door frames out of square. The door won’t close flush, gaps appear at the header, and homeowners assume they need new parts. Often they need track realignment ($120-$240) and frame adjustment, not a full hardware replacement.
- Opener motors burned out by failing springs. A torsion spring nearing failure doesn’t always snap dramatically. Sometimes it loses tension gradually, forcing the opener to lift 150-350 pounds it was never designed to carry. The motor overheats, the internal gears strip, and the homeowner replaces a $300 opener when a $180-$340 spring repair would have saved it.
- Weather seal destroyed by temperature extremes. Somerset’s subtropical baseline lulls homeowners into thinking freeze damage isn’t a risk. The 2021 ice storm proved otherwise. Now we see seals that cracked in the cold and were baked rigid by the following summer, leaving gaps that admit dust, water, and pests.
- Legacy doors with non-standard dimensions. Manufactured home conversions to enclosed garages are common in Somerset’s rural-to-suburban transition zone. These often have rough openings that don’t match standard door sizes, requiring custom-cut track, specialized jamb hardware, or creative retrofit solutions rather than off-the-shelf replacement.
Pricing for Garage Door Parts in Somerset, TX
We believe in upfront pricing. The flat price is stated before any work begins, and it does not change once we start. Here are the ranges for common parts repairs in Somerset’s market:
| Service | Price Range in Somerset |
|---|---|
| Spring Repair | $180-$340 |
| Cable Repair | $130-$250 |
| Track Realignment | $120-$240 |
| Roller Replacement | $110-$220 |
| Panel Replacement | $250-$500 |
What moves the price? Spring count (single vs. double), door weight and height, whether the drums and cables need simultaneous replacement, and accessibility. A standard 16-foot sectional door with two springs, accessible headroom, and no secondary damage will land near the lower end. A heavy custom door with seized hardware and clay-shifted framing will run higher.
Estimates are free. Call (210) 972-1317 and we’ll give you a straight answer over the phone for most common scenarios, or schedule a no-charge visit if we need to see the door.

FAQs - Garage Door Parts in Somerset
It’s usually your foundation responding to soil movement, not a faulty door. Somerset’s expansive black clay swells when wet and shrinks when dry, racking garage door frames out of square seasonally. The door itself is fine; the track needs realignment and the frame may need shimming. We see this repeatedly in this ZIP code, especially after the long dry summers followed by heavy fall thunderstorms. Track realignment in Somerset runs $120-$240. Call (210) 972-1317 for a free look - we’ll tell you if it’s soil movement or actual hardware failure.
If the motor runs but the door barely moves or reverses immediately, the spring is likely failed or failing. A healthy opener should not strain to lift the door. On a mid-century ranch in the Somerset area off TX-16, we answered a call where the homeowner swore the opener was dying - the motor strained and reversed mid-travel. Our tech found the real problem: two snapped torsion springs on a heavily-used sectional door, plus drums and cables that had gone slack and thrown the track alignment off after the clay shifted. We replaced both springs with high-cycle units, re-tensioned the cables, realigned the track, and reset door balance so the opener stopped working overtime. Spring repair runs $180-$340; a misdiagnosed opener replacement would have cost far more for no reason.
High-cycle torsion springs with galvanized or coated wire rated for corrosion resistance. Standard springs use grease that thins and migrates in sustained 100°F+ heat, accelerating wear. We specify springs with higher cycle ratings than the originals because Somerset’s climate and soil conditions increase annual open-close cycles - more manual operation when openers fail, more adjustment cycles after clay shifts. The right spring costs no more to install but lasts years longer. We’ll match the wire size, inside diameter, and length precisely to your door weight.
Most legacy doors can be repaired. We carry springs, cables, and hardware for one-piece doors and early sectional units that haven’t been manufactured in decades. The question is whether the door itself is structurally sound - rusted bottom sections, rotted wood rails, or cracked panels may make replacement the better money. We’ll inspect and give you both numbers: repair cost and replacement cost. No pressure. The 90-Day Done Right Promise covers either path. For manufactured home conversions with non-standard rough openings, repair or creative retrofit is often the only practical option.
The temperature swing is brutal on rubber and vinyl compounds. Somerset’s seals face 100°F+ summer heat that bakes them brittle, then occasional hard freezes like 2021 that crack them, then heavy rain that tests the compromised material. The clay dust that blows through a failing seal also abrades rollers and track. We install EPDM or silicone-blend seals rated for wider temperature ranges than standard PVC, and we check frame squareness because a racked frame tears seal faster than a square one. Annual inspection and replacement as needed is more economical than letting seal failure cascade into track and roller damage.
