Fast, Reliable Door Installation Across San Antonio
Door installation in San Antonio runs $900-$2,800 for a standard single entry door replacement, and $2,400-$6,500 for French or double door systems, including materials and labor. Most jobs in San Antonio are completed in one day once the measured survey is done and the door is on order. But the real question for San Antonio homeowners is not just price, it’s whether the installer knows what’s behind the jamb before the first screw comes out. We do. At Sightline Windows & Doors, every San Antonio job starts with a measured survey you keep, a written price before work begins, and a documented photo record when it’s done. Call (509) 265-6387 to schedule your free estimate.
Why Sightline Windows & Doors Is San Antonio’s Preferred Door Installation Company
San Antonio homeowners do not need a contractor who makes promises. They need one who writes the number down. That is the entire premise of the Haven Standard, the operating framework Sightline has run on since 2012, across more than 18,000 installed openings. Clause One is the one that matters most: the written quote cannot differ from the measured survey. If the survey says a 36-inch rough opening, the quote says a 36-inch rough opening, and the invoice matches both. No exceptions.
Our San Antonio crews are background-checked, uniformed, and identified by license number before arrival. That is Haven Clause 3, Verified Crews. The person who measures your door in Monte Vista is the same person who comes back to install it. And every completed job, from a single entry door in Stone Oak to a double French system in Alamo Heights, leaves with a photo record showing the work at each stage, plus the 365-Day Done Right Promise: if it is not done right, we make it right. Written into the contract, not offered as a courtesy.
Sonia Raman leads the San Antonio operation with the same standard the brand has held since 2012: evidence before emotion, written prices before tools, and no urgency theatre. If you want to know what a door replacement in San Antonio will cost, we will tell you in writing before you commit to anything.
Our Door Installation Services in San Antonio

Entry Doors
A new entry door in San Antonio does more than change the look of your front elevation. It changes how your house handles heat, moisture, and security. We install entry doors from Therma-Tru, CWS, and CGI, specified by what your opening actually needs. In older San Antonio neighborhoods like Beacon Hill and Tobin Hill, that often means dealing with out-of-square openings from decades of Vertisol clay movement. We measure the frame, not just the slab, and shim to square before we hang the door. The price for a standard entry door replacement in San Antonio runs $900-$2,800 depending on glass package, frame condition, and hardware grade.

Hurricane-Proof Front & Entry Doors
San Antonio sits far enough inland that hurricane landfall is rare, but straight-line winds and hail from severe thunderstorms are not. Impact-rated entry doors from CGI and CWS are built to withstand windborne debris and pressure cycling. For homes in the northwestern suburbs around Helotes and the far West Side, where exposure is higher, we frequently specify a CGI impact-rated slab with laminated glass interlayer. These systems start around $2,200 in San Antonio and go up based on size and finish. You get a documented pressure-rating label with the install, not a verbal claim.

French & Double Doors
French doors in San Antonio are beautiful and demanding. They have twice the slab, twice the weatherstripping, and twice the failure points of a single entry. The biggest issue we see in San Antonio is header sag over wide openings, especially in the post-1970s brick-veneer tracts of Stone Oak and Converse where original headers were sized to minimum code. We check the header, the king studs, and the sill before we quote. The price range for a full French door replacement in San Antonio is $2,400-$6,500 installed, depending on whether we are replacing a slider or a hinged pair, and whether the surrounding framing needs correction.

Replacement Doors
Replacement doors are the bulk of our work in San Antonio. The city’s inner ring is full of late-1800s to 1930s homes with original wood doors that have been painted, planed, and patched for generations. The suburbs are full of original aluminum and early vinyl units now 25 to 40 years old. A typical replacement door job in San Antonio runs $900-$2,400 for a single slab, more if the rough opening needs reframing. We include disposal of the old door and a written scope that lists exactly what we are doing and what it costs.

AfterTrusted Brands We Service in San Antonio
We work with eight manufacturer lines and specify by performance tier and price range, not by margin. In San Antonio, three brands get specified most often: CWS for mid-range energy-efficient entry doors, CGI for impact-rated front doors on exposed lots, and Therma-Tru for the wide variety of style options that historic districts and style-conscious neighborhoods demand. ES Windows and Eco Window Systems in San Antonio appear on higher-end custom projects where sightline and frame profile matter. We keep stock profiles and replacement hardware for these lines available for faster turnaround in San Antonio, which means fewer weeks waiting on a factory order for a slab you need now.
Common Door Installation Problems We See in San Antonio Homes

- Doors that stick and bind by July. San Antonio’s Vertisol clay expands when wet and contracts when dry, and it does both dramatically. Frames in older neighborhoods like Jefferson and Dignowity Hill move with the soil, which is why a door that closes fine in January binds in August. We correct this with adjustable hinges, frame shimming, and threshold adjustment, and we tell you if the movement is severe enough to warrant a foundation consult before we sell you a new door.
- Historic district door replacements gone wrong. The Historic and Design Review Commission has required homeowners in King William and Monte Vista to remove newly installed off-profile replacement doors at their own expense. We pull HDRC permit history before quoting any door job in the city’s seven designated historic districts. It is the first thing we do, not an afterthought.
- Undersized or rotted headers above wide openings. French doors and double doors need real structural support. In San Antonio’s 1960s and 1970s tract housing, we regularly find headers that were undersized even for the original single door. When we open the wall, we assess the header, and we price any reinforcement in writing before we proceed.
- Termite damage at the jamb and sill. San Antonio’s warm, humid climate is friendly to subterranean termites. We have opened door frames in Monte Vista, Alamo Heights, and Olmos Park and found extensive termite channels behind the trim. The visible door was fine. The structure behind it was not. We document what we find with photos and give you a written scope for remediation before we hang the new door.
Pricing for Door Installation in San Antonio, TX
Here are the numbers, in writing, as Haven Clause 1 requires. A standard single entry door replacement in San Antonio runs $900-$2,800. A full French or double door system runs $2,400-$6,500. An impact-rated front door from CGI or CWS starts around $2,200. A storm or exterior door with laminated glass runs $700-$1,800.

FAQs - Door Installation in San Antonio

Yes. The HDRC has required homeowners to remove newly installed off-profile replacement doors at their own expense in at least one documented King William case, and contractors in Monte Vista and surrounding historic districts routinely pull permit history before quoting. The Commission governs San Antonio’s seven designated historic districts and requires new doors to match original profiles, materials, and details. We pull HDRC permit history before quoting any job in those districts, and we submit the application paperwork as part of the written scope. Call (509) 265-6387 if you suspect your home falls under HDRC review and want us to check before you buy a door.
Because San Antonio’s Vertisol clay soil expands with spring rains and contracts through the summer dry season, and it moves enough to rack door frames in older inner-city neighborhoods. A door that stuck in June may swing freely by September, and that movement is not a door problem, it is a frame problem. We correct it with shimming, adjustable hinges, and threshold work, and we tell you if the movement suggests a foundation issue that needs a separate professional. Bring us your sticking door and we will measure the frame before we sell you a replacement.
Sometimes, and in San Antonio’s older housing stock, more often than homeowners expect. Opening a jamb in a 1920s Craftsman or 1930s Spanish Colonial can expose knob-and-tube wiring, failed waterproofing, or undersized framing that is no longer code-compliant. The city requires corrections to meet current code when work exposes these conditions. We handle this by writing inspection allowances into the contract up front, and any surprise we find is priced and approved in writing before we touch it. You never get a change order you did not see coming. Call (509) 265-6387 and we will walk you through what your specific home is likely to trigger.
The CGI Estate Collection single entry door with a laminated glass interlayer is the most specified impact-rated front door for homes in Helotes, the far West Side, and other northwestern San Antonio suburbs. It gives you a certified pressure rating for windborne debris, a real laminated glass package, and factory-applied finishes that hold up to San Antonio sun. The installed price in San Antonio starts around $2,200 depending on size and hardware. We document the pressure-rating label with your photo record.
Yes, if the old door has single-pane glass or failed seals. San Antonio summers routinely hit 100°F with Gulf humidity, and west- and south-facing doors take direct solar gain for hours every afternoon. A Low-E, argon-filled double-pane entry door cuts that heat transfer measurably, typically reducing cooling load at that opening by 25-40% compared to single-pane. The return is faster in San Antonio than in most Texas cities because the cooling season runs March through October. We give you the U-factor and SHGC on your written quote so you can compare doors by the numbers, not by the brochure. Call (509) 265-6387 for a measured survey and a written price.
