Fast, Reliable Window Replacement Across San Antonio
Window replacement in San Antonio costs $850-$2,400 per opening for a standard insert in a modern home, while full frame replacement on the town’s historic wood-frame houses typically runs $1,400-$3,800 per window because the rough openings are rarely square or standard. Lead times for custom units run four to eight weeks; labor is usually one to three days once materials arrive. We know this market because we work it every week. Call (954) 280-4413 for a free, written estimate and a side-by-side look at what fits your San Antonio home.
San Antonio is not a typical Florida subdivision. It is an 1881 planned settlement built by Cuban Catholic colonists, and the original town grid still stands. That means the window openings on Jessamine Road, Curley Street, and Pennsylvania Avenue were framed by hand, before building codes, before standardized lumber. Our crews measure every opening twice and order glass cut to the actual frame, not to a manufacturer’s assumption of what a Florida house should be. If you live in one of those older homes near the town center, you already know the difference between a window that drops in and one that gets built to fit.
Why TruePane Windows & Doors Is San Antonio’s Preferred Window Replacement Company
TruePane has served Pasco County homeowners since 2008 through the craft tradition Dale Kessler started formalizing in 2008. The work we do in San Antonio draws on that full history, because this town’s housing stock predates most of the contractors now working in Wesley Chapel. Our technicians understand wood-frame construction, sash-weight pockets, and the way a 1910 jamb moves after a century of settling. That is not something a franchise crew picks up in a training video.
San Antonio homeowners call us because a live person answers, 24 hours a day, seven days a week. No phone tree. No callback form. You call, you talk to someone who can schedule a site visit to San Antonio directly. Our technicians are background-checked and uniformed. They show up when they say they will, and they treat your house the way they would treat their own mother’s. Each quote is written on paper, line by line, so you see exactly what you are buying before you sign anything.
Every job carries the Done Right Promise. If the window is not right, we make it right. No paperwork fight, no fine print. And under The Keystone Standard, both manufacturer warranty layers are registered in writing before the truck leaves your driveway. The durations are stated on the invoice. You will not have to chase a warranty registration number later.
We also know the terrain. San Antonio sits on genuinely rolling hills, uncommon for Florida. Older parcels near the historic core settle unevenly, and that throws exterior door and window frames out of plumb. We see it on nearly every pre-WWII home we visit. A company that only does new construction in flat subdivisions will not catch it. We do, because we look for it first.
Our Window Replacement Services in San Antonio
Full Frame Replacement
When the original wood frame has rotted or shifted too far to hold a new unit securely, full frame replacement is the right call. In San Antonio’s 1880s-1930s homes near the old railroad depot and along the original settlement grid, we often find sills gone soft from decades of inland humidity. We remove the old window down to the studs, rebuild the rough opening square and true, install proper flashing, and set the new unit. The price range for this work in San Antonio is $1,400-$3,800 per opening depending on size, exterior cladding, and how much structural repair the opening needs.

Insert Window Replacement
An insert, or pocket replacement, fits a new window inside the existing frame when that frame is still sound. It costs less and goes faster, typically $850-$2,400 per window in San Antonio. But an insert only works if the frame is plumb and square. On older homes with settled jambs, we will tell you honestly if an insert leaves you with a window that binds or leaks. Some companies will sell the insert anyway and walk away. We will not.

Storm Window Replacement
San Antonio is not coastal, but Pasco County’s convective storm season is real. High winds and driving rain are part of every summer. We replace failed storm windows and upgrade to impact-rated units where the home’s exposure warrants it. For historic wood homes, we can supply storm sashes that preserve the original interior window profile while adding a modern protective outer layer. Pricing for storm window replacement in San Antonio runs $600-$1,800 per unit depending on size and impact rating.

Energy-Efficient Upgrade
Central Florida’s inland humidity is relentless. Older single-pane windows in San Antonio let that moisture in and let your cooled air out. We upgrade to low-E argon-filled insulated glass units that cut solar heat gain and condensation. For the historic homes, we match the glass package to the original sightlines so the house keeps its character. Energy-efficient upgrades in San Antonio typically run $950-$2,500 per window. The utility savings start the first month, but the comfort difference is immediate.

Trusted Brands We Service in San Antonio
We are an authorized installer for more than a dozen manufacturer lines, and in San Antonio we find ourselves reaching for three most often:, and ES Windows. Marvin’s wood windows let us match the millwork proportions of a 1910 bungalow. Andersen’s composite lines work well for the mid-century ranches on the town’s rural outskirts. ES Windows gives us high-humidity-rated aluminum and impact lines that hold up in Pasco’s storm season without demanding the maintenance of raw wood. We quote manufacturer lines side by side on paper, so you see the difference in build, warranty length, and price before you choose. We also carry the hardware and weatherstripping to service existing units from these brands across San Antonio.
Common Window Replacement Problems We See in San Antonio Homes
- Out-of-plumb rough openings on the town’s rolling hills. Differential settling on San Antonio’s elevated parcels knocks frames out of square by a quarter inch or more. An insert-only replacement will leave chronic latch misalignment and air leaks if the jamb is not reset first.
- Custom units arriving with rough-opening mismatches. National brands build to modern framing dimensions. The 1880s-1930s homes in the original settlement grid were framed by hand to no standard. A production window dropped into that opening needs expensive on-site jamb modification we would rather avoid by ordering true custom sizing from the start.
- Inland humidity rotting original wood sashes. San Antonio sees no salt air, but year-round moisture does the slow work on soft pine sashes and frames. Homeowners who replace with fiberglass or vinyl without considering the historic millwork profile lose the reveal lines and proportions unique to this planned Cuban settlement.
- Fogged seals from trapped moisture between panes. Failed insulated glass units are common across Florida, but in San Antonio’s humid inland climate the failure shows up faster when original units were not rated for high humidity. Our replacement glass carries humidity-rated seals and a written warranty registered before we leave the property.

How San Antonio’s Historic Rough Openings Change the Job
In San Antonio’s pre-WWII town grid, the original wood-framed homes were built with non-standard rough openings. There was no standardized lumber dimension when those houses went up in the 1880s through the 1930s. A builder cut openings to fit the sash he had on hand or the plan a colonist brought from Cuba. That means a modern 36-by-60 production window does not simply slide into the hole. Our crews regularly fabricate true custom-sized replacement windows for these homes, something almost never required in the surrounding Wesley Chapel tract builds with their uniform modern framing.
That is the difference between a contractor who works in San Antonio and one who works near it. We have rebuilt enough of those openings to know when a jamb can be saved and when it needs to come out. On a 1910 bungalow near the old town center, our crew replaced a swollen double-hung unit with a custom Marvin wood window after discovering the original jamb had shifted out of plumb by nearly half an inch from differential settling. We rebuilt the rough opening, installed flashing tape and low-E argon-filled glass, and fixed the threshold gap that had plagued the homeowners for years. That is not a brochure story. It is a Tuesday.

FAQs - Window Replacement in San Antonio
Many of the older wood-frame homes near San Antonio’s original settlement grid do require full frame replacement because the original rough openings are out of square and the sills have rotted from inland humidity. An insert can work when the existing frame is still structurally sound and plumb, which is more common on the mid-century ranches and newer builds on the town’s outskirts than on the historic homes near the center. Call (954) 280-4413 and we will measure the frames and tell you which option is honest for your house.
We order true custom-sized units or fabricate them ourselves to match the existing rough opening and muntin profile. Standard window manufacturers size their products to modern framing, so on a San Antonio bungalow we work backward from the original sightlines, choose a wood window line like Marvin that allows custom dimensions, and match the glass-to-frame ratio so the face of the house does not change. Estimates for custom matching work are free, so call (954) 280-4413 and we will walk you through what the openings actually measure.
Low-E argon-filled insulated glass cuts solar heat gain and reduces condensation on the interior pane, which matters more in San Antonio’s humid inland air than in a dry climate. The argon fill slows heat transfer between the panes, and the low-E coating reflects infrared heat back outside, keeping the house cooler with less strain on your AC. For historic homes, we match the glass package to the original window proportions so you gain efficiency without losing the architectural character. Call (954) 280-4413 for a quote on an energy-efficient upgrade.
We reset the rough opening before installing the new window. That means removing the old unit, checking the studs and sill for true, shimming and rebuilding where the settling has pulled the frame out of square, and then setting the new window into a corrected opening. If we only dropped an insert into the existing out-of-plumb frame, you would get a window that binds or leaks. We will not do that. Call (954) 280-4413 for a free estimate and we will show you exactly what the measurements say.
Yes. We regularly order custom millwork to match the interior casing, stool, and apron profiles on San Antonio’s older homes. The casings on those 1880s-1930s houses were often milled locally or built by hand, and off-the-shelf replacements do not match. We measure the existing profile, match the wood species, and order the millwork so the new window reads as part of the original room. Add $150-$600 per opening for custom millwork matching depending on complexity. Call (954) 280-4413 and we will bring profile samples to the estimate.
