We’ve been working in southern Bexar County long enough to know that Somerset isn’t just another dot on the map. The houses here tell a story: mid-century ranches on acreage off TX-16, manufactured homes converted to enclosed garages along county roads, and newer subdivisions creeping south from San Antonio along US-181. Each comes with its own door problem. The clay soil beneath them is the quiet culprit most homeowners never see coming.

Our Garage Door Installation Services in Somerset
New Door Installation
A new garage door installation in Somerset starts with understanding what the house actually needs. The mid-century ranches common west of TX-16 often have original 16-foot openings with aging extension spring systems that have outlived their safe service life. Newer tract homes near the US-181 corridor tend to have standard rough openings that accept stock doors, but the converted manufactured homes scattered throughout the area frequently don’t. We measure every opening ourselves, check the header and side jambs for square, and quote a flat price before any work begins. A typical new door installation in Somerset runs $700-$2,200 depending on size, material, and whether the track and hardware need replacement.
Single Car Door
Single-car doors, usually 8 or 9 feet wide, are common on the older ranch homes and original manufactured-home carports we see around Somerset. Many of these openings were never built to modern standards. The framing may be rough-cut lumber, the header might be undersized, and the slab could have shifted with the seasonal clay movement. We don’t just hang a door. We assess whether the structure can support a modern insulated steel door or whether a lighter-duty option makes more sense for the long term. Our Garage Door Installation team carries single-car door sections and track systems on every truck.
Double Car Door
Double-car doors, 16 feet wide and up, put serious load on their hardware. In Somerset, that load gets amplified. The expansive black clay beneath the slab swells in wet weather and shrinks in drought, racking the frame and binding the door. A heavy double-car door on a misaligned track will burn out its opener in months, not years. When we install a new double-car door, we check the opening for square, upgrade to high-cycle torsion springs rated for the actual weight, and use heavy-duty track brackets that can tolerate minor seasonal shifts without throwing the alignment. This is where our field experience in Somerset pays off. We’ve seen what happens when a standard installation meets this soil.
Custom Garage Door
Custom garage door work is not a sideline for us. It’s a necessity in Somerset. The manufactured-home conversions, in particular, often have rough openings that don’t match any standard door size. We’ve built solutions for 8-foot-3-inch widths, non-standard heights, and openings where the left jamb sits an inch lower than the right because of slab settlement. Custom sizing means custom ordering, but it also means we engineer the track and hardware to fit the actual opening, not force a stock door into a space that will fight it every cycle. We quote custom jobs with the same flat-price approach: measure, specify, price in writing, then install.

Trusted Brands We Service in Somerset
We carry and install doors and openers from the manufacturers that have proven they last in South Texas conditions. That includes Clopay and Amarr steel doors, Wayne Dalton’s engineered options, and opener systems from LiftMaster, Chamberlain, Genie, and Craftsman. We keep common sizes and parts on our trucks, which means a Somerset homeowner isn’t waiting two weeks for a back-ordered panel while their garage sits open. Our technicians are factory-familiar with every brand we sell, so installation follows manufacturer specification, not guesswork. Raynor hardware is also in our regular inventory for homeowners who want that specific track and spring package.
Common Garage Door Installation Problems We See in Somerset Homes
- Frames racked out of square by expansive clay soil. Somerset’s Vertisol soils swell and shrink with wet-dry cycles, pushing garage door frames out of alignment seasonally. The door binds, won’t close flush, or gaps at the bottom. Homeowners often assume the door or opener has failed. We check the slab and header first. Track realignment and a new weather seal usually solve it, at $120-$240.
- Legacy extension springs and openers past safe service life. The mid-century ranches and early manufactured homes in Somerset still run original extension spring systems from the 1990s or earlier. These springs sag, lose tension unevenly, and snap without warning. The openers strain, overheat, and burn out. We replace with high-cycle torsion systems rated for 25,000 cycles. Spring repair runs $180-$340.
- Non-standard rough openings in converted manufactured-home garages. Enclosing a carport or adding a garage to a manufactured home often produces an opening that doesn’t match stock door dimensions. We measure, fabricate custom track and hardware, and source made-to-fit door sections. This is custom work, priced by the job, starting around $700.
- Heat-degraded components in unventilated garages. Somerset’s 100°F+ summer days cook opener motors and turn torsion spring grease to varnish. Lower vinyl door sections warp. We specify insulated doors and proper ventilation where possible, and we use high-temp lubricants and components rated for the South Texas climate.
Pricing for Garage Door Installation in Somerset, TX
We quote every job in person, measure the opening ourselves, and give you a flat price before any work starts. No surprises on the bill. Here is what typical garage door work costs in the Somerset market:

| Spring Repair | $180 - $340 |
| Track Realignment | $120 - $240 |

What moves the price on a new door installation: size (single vs. double), material (steel, wood, composite), insulation rating, window inserts, and whether the existing track, springs, and opener can be reused. A basic uninsulated single-car steel door on existing hardware sits at the low end. A fully insulated double-car door with new torsion springs, heavy-duty track, and a belt-drive opener hits the high end. We walk you through the options, explain the trade-offs, and let you decide.

FAQs - Garage Door Installation in Somerset
It’s usually the soil, not the door. Somerset’s expansive black clay swells when wet, racking the frame out of square and preventing the door from seating flush. We see this call every fall after the first heavy storms. Our tech checks the slab and header before touching the hardware. Track realignment and a new weather seal typically fix it. Call (210) 972-1317 and we’ll come diagnose it.
Repair makes sense when the door itself is sound and the problem is isolated to springs, cables, or an opener. Replace when the door has structural rust, the panels are delaminating, or the hardware is so obsolete that parts are no longer manufactured. For Somerset’s mid-century ranches, we often find original extension spring systems and openers from the 1990s that have exceeded their safe service life. At that point, a new door with modern torsion springs and a current opener is the safer long-term investment. We’ll give you an honest assessment either way.
A standard torsion spring rated for 10,000 cycles lasts 7-12 years in Somerset’s heat, depending on daily use. We install high-cycle springs rated for 25,000 cycles on most new installations, which typically doubles that lifespan. The 100°F+ summers degrade grease and accelerate metal fatigue, so we use high-temp lubricants and recommend annual inspection. The February 2021 ice storm also proved that cold snaps, rare as they are, can seize and snap springs that were already near end of life.
Yes. This is custom work we do regularly in Somerset. Manufactured-home conversions often produce rough openings that don’t match stock door dimensions. We measure precisely, fabricate custom track and hardware, and source made-to-fit door sections. The job takes longer than a standard installation and costs more, but we quote it flat before we start. Call (210) 972-1317 for a free measure and written estimate.
The opener is working harder than it should because something else is wrong. In Somerset, the most common cause is a frame racked out of square by clay soil movement, which binds the door in its track. The opener motor overheats trying to overcome that drag. Less commonly, the springs are incorrectly sized or have lost tension unevenly. We check the full system: slab, frame, track, springs, and opener. Fixing the root cause protects the opener from burning out entirely. Call us at (210) 972-1317 and we’ll sort it out.
