Fast, Reliable Door Installation Across La Coste
Door installation in La Coste, TX typically runs $900-$3,400 depending on the door type, frame condition, and what we find once the old unit comes out. Most entry and storm door jobs are completed in a single visit, though homes on the older ranch lots along Castro Avenue and near the US-90 corridor sometimes need frame re-alignment first because of the Medina County clay. If your La Coste door sticks in August or lets dust blow through the sweep, call (888) 635-0804 for a free estimate. We’ll send a background-checked technician who knows what this soil does to a door frame.
Why TruePane Windows & Doors Is La Coste’s Preferred Door Installation Company
TruePane has worked on enough La Coste homes to know the real issue is rarely the door itself. It’s what the clay has done to the opening. Our crews serve La Coste regularly, and we’ve re-squared more twisted jambs in this town than we can count. Dale Kessler founded this company in 2008 on a rule that still governs every install: if the pane is not true, the job is not done. In La Coste, “not true” usually means a frame racked by seasonal soil movement.
Homeowners here tend to call rather than click. They want to talk to a live person who knows their street and their house. A live person answers our phone 24 hours a day, 7 days a week, not a voicemail tree. Our Door Installation team works in La Coste homes the way they’d work in their own mother’s: measuring every opening twice, quoting manufacturer lines side by side on paper, and registering both warranty layers before the truck leaves the driveway. That’s The Keystone Standard, and it’s in writing every time.
We also stand behind the work with a Done Right Promise. If something isn’t right, we make it right. No paperwork fights, no arguing. That promise matters in a town where a door that latched in May can bind by August, and the repair might involve resetting the striker plate rather than replacing the whole unit.
Our Door Installation Services in La Coste
Entry & Swing Doors
A new entry door in La Coste does more than change the look of the house. It seals the biggest gap in a ranch home built in the 1960s through 1980s, many of which still have the original hollow-core exterior door. Those old units offer almost no insulation against south Texas heat, and the weatherstripping is usually gone. We install fusion-welded frames and properly flashed sills so the door closes true and the 100°F air stays outside. Entry door replacement in La Coste typically runs $1,400-$3,200 installed, depending on the door material and whether the rough opening needs re-squaring.

Storm Doors
The open ranchland west of town funnels south and southwest wind straight into La Coste neighborhoods, and a flimsy storm door will not survive it. We spec storm doors with reinforced corners and dual-sweep weatherstripping for houses along the open corridors near US-90. A good storm door also adds a second layer of dead air against the July heat, which matters when the front door is original hollow-core. Storm door installation in La Coste runs $600-$1,500, with the higher end covering full tear-out of a rusted old frame.

Double & French Doors
Double and French door installs in La Coste come with a specific complication: the two-door unit spans a wider rough opening, which means more places for a racked frame to bind. On a ranch home with even a quarter-inch of seasonal movement, both slabs will drag at the meeting stile by mid-summer. We set double-door frames with shims tied to the existing movement, not just plumb to the wall, and we re-check the striker alignment before we leave. Expect $2,200-$4,800 for a quality double or French door install in La Coste, including the additional frame work these openings usually require.

Pivot Doors
Pivot doors are a newer request in La Coste, mostly from homeowners along the western edge where San Antonio exurb growth has crept past Von Ormy. A pivot door carries its entire weight on floor and header hardware instead of side hinges, which means the rough opening has to be dead square. Given what Medina County clay does to an opening over the course of a year, we check for movement history before we quote a pivot install. Pivot door installation in La Coste starts around $3,000 and goes up from there, and we’ll tell you honestly if your frame is a poor candidate before you spend a dollar.

Trusted Brands We Service in La Coste
We’re an authorized installer for more than a dozen manufacturer lines, and for La Coste homes we most often quote PGT, CGI, and CWS because those lines hold up to the sun exposure and wind loading this area dishes out. We keep common replacement parts and weatherstripping on the truck for those brands, so a storm door sweep or striker adjustment doesn’t turn into a two-week wait. We quote manufacturer lines side by side on paper so you see exactly what you’re buying, and both warranty layers get registered in writing before we head back to the San Antonio office. For Door Installation in La Coste, that means no surprises about what’s covered.
Common Door Installation Problems We See in La Coste Homes
- Frames racked by clay heave. La Coste sits on Medina County Vertisol clay that swells with spring rains and shrinks in summer drought. A door that latched fine in April drags at the top corner by August, and the fix starts with re-squaring the rough opening, not just swapping the slab.
- Open-wall discoveries on older ranch homes. When we pull a hollow-core door on a 1960s-1980s home, we sometimes find the original header is undersized for a modern pre-hung unit, or the wiring is not up to current code. A permit can trigger an energy-code upgrade on an exterior wall, which changes the quote. We write allowances into the contract and price any surprise in writing before we touch it.
- Failed weatherstripping and door sweeps. The south Texas sun bakes rubber weatherstripping brittle within a few summers, and the wind from open ranchland drives dust through the gap. A door that looks fine from the yard can be leaking 100°F air around the entire perimeter.
- Rotting subfloor under the sill. Storm-driven south wind pushes rain under a poorly flashed sill, and the subfloor rots before the finish trim is even painted. On a 1970s ranch home off Castro Avenue, we pulled a hollow-core exterior door to find the original jamb twisted a full half-inch out of square from clay heave. We re-squared the opening, installed a fusion-welded frame, re-flashed the sill, and reset the striker plate so the new door closed true, with a written note that soil movement might call for a seasonal adjustment come drought.

La Coste pricing runs slightly below San Antonio on labor because the drive is shorter, but the clay soil work often adds a frame re-alignment line item that other towns don’t need. We write that into the quote up front, so the number we give you is the number you pay. No change orders unless you approve them in writing first.

FAQs - Door Installation in La Coste
Blame the Medina County Vertisol clay under your house. It absorbs spring rain and swells, lifting sections of the slab unevenly, then shrinks in summer drought and the frame settles back out of square. The door slab that tracked fine in May binds at the top corner by August because the rough opening has shifted. We fix it by re-squaring the frame and resetting the striker plate, and in many La Coste homes a seasonal adjustment becomes repeat work at the same address. Call (888) 635-0804 and we’ll take a look.
Most La Coste door replacements don’t require a full wall opening, but when an oversized double door or pivot door goes into a ranch home built between the 1960s and 1980s, the rough opening sometimes needs to be enlarged. At that point, the permit typically triggers energy-code compliance for the exterior wall, which can mean adding insulation, replacing undersized headers, or bringing old wiring up to current code. We inspect first, write allowances into the contract for exactly these possibilities, and any surprise is priced and approved in writing before we touch anything. That’s how we keep your quote honest.
We re-square the rough opening rather than force a new pre-hung unit into a racked frame. That means pulling the old jamb, checking the king and jack studs for twist, and re-shimming the opening so the new frame sits true to the slab, not just to the drywall. On a 1970s home off Castro Avenue, we found a jamb twisted a full half-inch out of square from clay heave and had to re-flash the sill before the new entry door would close true. Expect $150-$450 for that extra frame work on top of the door install, and we’ll tell you up front if your house needs it.
Yes, if you spec it right. The open country west of town lets south and southwest wind build with almost no obstruction, and a big-box storm door with a thin aluminum frame will rack and rattle within a season or two. We order storm doors with reinforced corners, tempered or impact-rated glass where needed, and dual-sweep weatherstripping that stays tight when the wind loads the panel. For La Coste homes on the western and southern edges, near the open ranchland, we quote PGT or CGI storm lines that are built for this kind of loading. Call (888) 635-0804 to talk through what your house actually faces.
It’s probably a hollow-core unit from the 1960s-1980s, the original door on many of the town’s ranch homes. Hollow-core doors have almost no thermal mass and no insulation, so after a few hours of south Texas sun they conduct heat straight into the house. The fix is a well-sealed insulated door, often paired with a storm door to create a buffer. Entry door replacement in La Coste with an insulated steel or fiberglass unit typically runs $1,400-$3,200, and you’ll feel the difference on the first hot afternoon.
