Fast, Reliable Window Installation Across San Antonio
Window installation in San Antonio runs $650 to $2,400 per opening for most homes, depending on whether the job is a straightforward insert into a sound frame or a full-frame tear-out on an older structure. If you live in the historic colony core off Curley Road, expect the higher end of that range more often than not. TruePane Windows & Doors serves San Antonio with background-checked, uniformed technicians who measure every opening twice and quote manufacturer lines side by side on paper. Call (813) 320-9346 for a free estimate, and a live person answers, day or night.
We know this town’s split personality. One house needs a vinyl insert into a clean 1990s rough opening; the house next door was framed in 1910 and needs the opening rebuilt before a window can be set. That range is exactly why a local install crew matters here in San Antonio more than in the bigger Tampa bedroom communities.
Why TruePane Windows & Doors Is San Antonio’s Preferred Window Installation Company
Dale Kessler founded TruePane in 2008, but the glazing tradition behind the company runs back many years across two generations of family craft. The founding rule stays on the whiteboard in our shop: if the pane is not true, the job is not done. In San Antonio, that rule gets tested more than most places, because this town’s housing stock swings between century-old wood frames and brand-new tract homes off SR-52 within a single mile.
San Antonio homeowners tell us the same things: they want a company that answers the phone, shows up when it said it would, and stands behind the work in writing. That’s why we register both manufacturer warranty layers on paper before the truck leaves the driveway, and why every job carries the 90-Day Done Right Promise. No paperwork fights, no arguing. If it is not done right, we make it right. That’s the deal.
We’ve pulled permits in Pasco County long enough to know what the inspectors look for in the historic core and what the newer subdivisions require for wind-load product approvals. A crew that has only worked new construction will not catch a hollowed-out pine jamb behind the trim. Ours does. It’s the difference between an inspection that passes and a redo you pay for twice.
Our Window Installation Services in San Antonio
Fixed & Picture Windows
Fixed windows are the workhorse of a San Antonio home that wants light without leaking air, and they cost $350 to $900 per unit installed in most local homes. In the older cottages near the colony center, a fixed picture window often replaces a failed wood-sash unit, and the opening frequently needs head and sill repair before the new frame goes in. We set the unit level, flash the perimeter with tape, and register the warranty before we leave. For a homeowner who plans to stay twenty more years, that’s the only way to do it.

Single & Double Hung Windows
These are the most common replacement windows in San Antonio’s mid-century ranch homes, and they run $550 to $1,700 per opening depending on size, material, and glass package. A double-hung that binds in July or won’t stay up in a Florida thunderstorm is usually a sign of a frame that shifted or rotted at the sill. We don’t set a window in a rotten jamb. We rebuild the opening, set the new unit square, and seal it so the humidity stays outside where it belongs.

Casement Windows
Casement windows give the best seal against San Antonio’s humid summers, an important detail for a town where the average dew point in August hangs in the mid-70s. They run $600 to $1,500 per opening here, and they are a strong choice for older homes where you want ventilation but do not want to lose the historic sight lines. We install fusion-welded frames with low-E argon-filled glass on most casement jobs, which keeps the cooling bill from climbing with the temperature.

Fixed & Picture Windows
A fixed window in a new tract home off the SR-52 corridor has to meet Pasco County’s wind-load design speed maps just like a coastal house, which many homeowners do not realize until the inspector asks for the product approval documents. We supply that paperwork with every quote for these homes. For a historic cottage in the colony center, the same fixed window often means a full-frame tear-out and a rebuilt rough opening. Two houses, same street, completely different jobs.

Trusted Brands We Service in San Antonio
TruePane is an authorized installer for more than a dozen manufacturer lines, and in San Antonio we work most often with Andersen, Pella, and Marvin products. Each carries different performance data for the Florida Building Code, and we quote side by side on paper so you can see the U-factor, SHGC, and wind-load product approval for each option. A live person answers the phone 24 hours a day, 7 days a week, not a call center. When you call about a window in San Antonio, you talk to someone who knows the difference between a 1910 pine jamb and a 2022 tract-home rough opening.
Common Window Installation Problems We See in San Antonio Homes
- Hollowed-out sills in historic homes: Original pine frames from the early 1900s have spent a century absorbing subtropical humidity and hosting Formosan termites. When trim comes off an insert job in the colony core, the rough opening often needs pressure-treated rebuilding before any window goes in.
- Failed permits on tract-home retrofits: A cheap quote that omits product approval documentation for impact-rated glazing gets flagged by Pasco County inspection. The U-factor and SHGC on the installed unit does not match the energy compliance path, and the homeowner pays for a redo.
- Wood rot hidden behind siding on SR-52 ranches: An installer who ignores a decayed jamb and sets a premium window over it seals the moisture in. The sill collapses within two seasons, and the warranty does not cover a bad rough opening.
- Warped frames from thermal cycling: Inland Pasco County still gets intense UV exposure and heavy summer thunderstorms, and that combination degrades vinyl seals and warps cheap frames faster than homeowners expect. A frame without a fusion-welded corner will leak before its time.
Pricing for Window Installation in San Antonio, FL
Window installation pricing in San Antonio breaks into two bands. In tract homes off the SR-52 corridor, a standard double-hung insert runs $550 to $900 per opening, while a casement or fixed unit runs $350 to $1,500 depending on glass and frame material. In the historic colony core, full-frame tear-outs with rough-opening rebuilding run $1,200 to $2,400 per opening and sometimes more when structural repair is extensive. A cheap insert quote on a 1920s cottage will not survive Pasco County inspection once the rot is exposed. Every quote we write in San Antonio is a fixed price, no change orders, with the product approval paperwork included. Call (813) 320-9346 for a free estimate, and we’ll walk the house with you.

FAQs - Window Installation in San Antonio
Pasco County requires a permit for any window replacement that changes the opening size or involves structural repair, which is nearly every job in the historic core. You need a product approval for the window with a wind-load rating that meets the county’s design wind speed map, plus a plan that accounts for full-frame structural repair when rot or termite damage extends into the framing. A compliant quote includes all of that paperwork. An insert-only plan submitted without the structural work gets rejected at inspection. Call (813) 320-9346 and we’ll walk your specific house through the sequence before anyone picks up a hammer.
Sometimes, but rarely without structural repair. Original pine frames in San Antonio’s oldest homes absorb decades of moisture and termite damage; once trim is pulled, many rough openings are too soft to hold an insert square. If the jamb compresses under a thumb screw, the opening gets rebuilt. If the wood remains sound, a properly measured insert works fine. The answer depends on what is inside the wall, not the age of the house alone. We measure twice and inspect the frame before we quote, so you know what you are getting into.
Impact glass is a component. A wind-rated product approval is the manufacturer’s documented test result showing the entire window assembly, frame, glass, hardware, and anchoring, meets the Florida Building Code’s wind-load requirements for Pasco County. A window can have impact glass and still lack the assembly-level approval an inspector requires. When we quote a window in San Antonio, we include the product approval document for the exact model we are installing, not a generic spec sheet.
If a storm damages a window, the insurance adjuster will ask for the permit, the product approval, and the installation record. A homeowner who has that paperwork documented gets a cleaner claim. A homeowner whose window was installed without documented wind-load compliance may find the claim reduced or denied, because the assembly was never proven to meet the required rating. That’s why we register both manufacturer warranty layers and leave the compliance documents with the homeowner before the truck leaves the driveway. It matters when the storm comes.
Builder-grade windows meet minimum code when installed correctly, but they are often the cheapest assembly the builder could source, and their seals and hardware do not always last a decade in San Antonio’s UV and humidity. Many homeowners in the SR-52 subdivisions replace those windows within ten to fifteen years with a better low-E and fusion-welded frame unit. The improved thermal performance cuts the cooling load in our summers, and the documentation path is already in place for wind-load compliance. It is a retrofit, not a rebuild, but it still needs the same paperwork.
If you live in San Antonio and you are tired of guessing whether a window job was done right, call TruePane at (813) 320-9346. A live person answers, we schedule the free estimate, and we put everything in writing before we start. Done right. That’s the standard.
