Replacing an exterior door in San Antonio usually takes one day once the new unit is on hand, and most homeowners pay between $1,800 and $4,200 for a quality fiberglass or steel entry door installed with new weatherstripping and hardware. That price covers the removal of the old door, disposal, shimming and leveling the frame, and a clean work area when our crew leaves. Lightwell Windows San Antonio works with the realities of this city’s homes: clay that moves, sun that bakes seals, and older neighborhoods where framing hides surprises. Call (325) 420-4173 and we’ll walk you through what your specific door project needs before anyone touches a hinge.
Key takeaways:
- Written pricing before work begins, covering the full job with no change-order surprises

- Crews that protect floors, furniture, pets, and kids’ schedules on every visit
- 365-Day Done Right Promise on every door we hang
Why Lightwell Windows San Antonio Is San Antonio’s Preferred Door Installation Company
We started as part of the Cedarwell network in 2010, and since then our San Antonio crews have learned what happens to doors in this specific climate. The Edwards Aquifer gives us hard water that films glass and speeds corrosion on hardware. The summer sun in areas like Alamo Heights and Shavano Park breaks down weatherstripping faster than manufacturers expect. And the clay soil under older neighborhoods keeps shifting, which means frames that were square in 1998 are racked by 2025. Knowing that ahead of time changes how we quote, how we prep, and what we inspect before the new door goes in.
Keith Yamada leads our San Antonio team, and he insists on one rule: the price we write down is the price you pay. That written quote includes the labor, the door, the hardware, the disposal, and the clean-up. If we open a wall and find rotten framing or shifted structure, we stop, document what we found, and put a revised number in writing before we do another thing. No one likes getting a bigger invoice at the end than the one they agreed to at the start. We built our reputation in San Antonio on not doing that to people.
Styles & brands we work with
Exterior Door Installation in San Antonio
Exterior Door Installation in San Antonio typically runs between $1,800 and $3,600 for a standard single entry door, and $3,200 to $5,800 when the job includes the kind of impact-rated door many Stone Oak and Cibolo-area homeowners request. The work involves pulling the old slab and frame, inspecting the rough opening for rot or racking, rebuilding or shimming the jamb as needed, installing a new sill pan where the old one has failed, and hanging the new door so it closes squarely with an even reveal on all sides. In San Antonio’s pre-1950 neighborhoods, this rarely stays a simple slab swap.
What We Inspect Behind the Trim
Once the old door comes out, we look at what’s behind it. In homes in Monte Vista and King William, undersized or rotted framing is common, and a door that looked fine from the inside may be held together by paint and luck. We’d rather show you a photo of what we found than bury a surprise in an invoice later.
Threshold and Sill Pan Work
San Antonio’s 1970s-to-2000s slab homes often have failed waterproofing at the threshold. Pulling an old door reveals subfloor rot that’s been quietly spreading for years. We address that before installing anything new, because a beautiful door on a rotten sill is just a future warranty claim.
French Door Installation in San Antonio
French Door Installation in San Antonio generally costs between $2,800 and $6,500 depending on whether you’re replacing a sliding patio door with a swinging French unit, upgrading an existing French door, or adding a new exterior opening. The job involves leveling two doors that must meet cleanly in the middle, which is harder than it sounds on a foundation that has moved. In San Antonio, where clay expansion and contraction are constant, we spend extra time on the threshold and the astragal so both panels seal tight through every season. Most San Antonio homeowners choose fiberglass for this application, because wood doors struggle with our sun.
Fiberglass vs. Wood in San Antonio’s Climate
ViewLux and Therma-Tru fiberglass French doors hold up better under continuous UV exposure than solid wood. They don’t swell in our humidity spikes, and they don’t warp when the sun hits the west-facing side of the house from noon to sunset. We still install wood where the architectural style calls for it in places like Olmos Park, but we’re honest about what the climate will do to it.
French Doors for Slab Homes
Many San Antonio ranch homes from the 1960s and 1970s were built on slabs with aluminum sliding doors. Replacing one of those with a French door means reframing the opening wider and redoing the waterproofing at the sill. We’ll explain that scope before you sign anything, and the written price includes every step.
Trusted Brands We Service in San Antonio
We stock local parts and components for the brands San Antonio homeowners ask for most. Therma-Tru fiberglass entry systems handle our sun without warping. ViewLux offers a clean, contemporary line that works beautifully in newer north-side homes. And for areas where wind-driven rain and storm events are a real concern, PGT and CGI impact-rated doors deliver the protection San Antonio building codes and insurance carriers increasingly expect. We recommend the brand that fits your home’s construction, your neighborhood’s exposure, and your budget, not the brand we happen to have in the warehouse.
Common Door Installation Problems We See in San Antonio Homes
- Racked frames on clay soil. Pre-1950 homes in Monte Vista and King William sit on expansive clay that swells and shrinks with rainfall. Door frames subtly fall out of square, and a deadbolt that worked for twenty years suddenly won’t line up with its strike plate.
- Rot hidden behind trim. When we pull an old door on a 1980s or 1990s slab home, we often find the rough opening’s lower framing has been wicking moisture for a decade. Nobody knew because the trim hid it.
- Sun-baked seals and swollen frames. Ten years of San Antonio UV exposure breaks down door weatherstripping to the point where air moves freely around the edges. The frame itself can swell enough that the door drags on the threshold.
- Cloudy, warped 1990s vinyl patio doors. North-side subdivisions from that era are full of vinyl sliders that have fogged between the panes and warped out of shape from heat and hard water. It’s a failure pattern we see weekly.

FAQs About Door Installation in San Antonio
Replacing an exterior door in an older San Antonio home often triggers requirements for tempered or safety glazing if the door includes glass within 24 inches of the door edge, plus current egress and threshold-height standards. On pre-1950 homes, especially in historic districts like King William, additional review may apply. We identify these items during our initial inspection and include any required code work in your written quote, with a clear explanation of why it’s needed. Call (325) 420-4173 and we’ll walk through what applies to your specific home.
We re-square the rough opening by shimming the jamb, and in more serious cases we pull the frame and re-install it on a properly prepared opening. San Antonio’s expansive clay moves with moisture, which is why a door that latched fine in 2010 may not close today. We address the root cause, not just the symptom, and we’ll show you exactly what we did before we put the trim back on. For a free evaluation of your sticking door, call (325) 420-4173.
Yes, impact-rated doors with low-E insulated glass reduce solar heat gain through the door itself and seal more tightly than older or builder-grade units. In a San Antonio summer, that means less heat entering the home and fewer cycles on your air conditioner. The energy savings are real, though they’re usually not the main reason people choose impact-rated doors; that choice is typically driven by storm protection and insurance requirements. Call (325) 420-4173 for an estimate that separates the door cost from the efficiency upgrades.
Two local factors combine: San Antonio’s intense UV exposure breaks down the vinyl and the seals, and the region’s hard water from the Edwards Aquifer accelerates clouding between panes. In neighborhoods built in the 1990s around Stone Oak and similar north-side areas, these doors often warp out of square, fog permanently, and stop sealing by the twenty-year mark. We replace them regularly with fiberglass units built for our sun load. Call (325) 420-4173 and we’ll tell you whether yours can be repaired or should be replaced.
In most cases, replacing a door in an existing opening does not require a permit in San Antonio, but adding a new opening, enlarging an opening, or making structural changes to framing does. We handle the paperwork when a permit is required, and we’ll tell you upfront whether your specific job falls under the permit threshold. Part of our no-surprise pricing is making sure you know the full scope, including permits, before work begins. Call (325) 420-4173 with your address and we’ll clarify the requirements for your property.
