Windows & Doors Services in San Antonio, FL
San Antonio’s oldest window openings don’t match modern framing charts. We know that because we’ve pulled trim from late-1800s rough openings and found pine frames hollowed by a century of heat, humidity, and termite pressure. Window and door work in San Antonio, FL splits into two very different jobs: full-frame tear-outs in the historic colony core, and Florida Building Code wind-rated installs in the new subdivisions pushing in from SR-52. If you’re weighing a replacement, a repair, or a first-time impact upgrade, call (813) 320-9346 and we’ll give you a straight answer on what your house actually needs. No pressure, no script.

Why San Antonio Homeowners Choose TruePane Windows & Doors
Most companies treat San Antonio as a detour between Dade City and Wesley Chapel. We don’t. Our crews know the old colony streets, the mid-century ranches on Curley Road, and the new builds along the SR-52 corridor. That matters when the opening in a 1905 cottage is an inch out of square and the “standard” insert won’t seal. Homeowners in Saint Anthony Estates and the neighborhoods off Lake Jovita Boulevard call us because we measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves the driveway. That’s The Keystone Standard, and it governs every job we do in San Antonio.
Our technicians are background-checked and uniformed. A live person answers the phone 24 hours a day, seven days a week. And when we say we’ll be there Tuesday at 8, we’re there Tuesday at 8. We stand behind the work for 90 days with the Done Right Promise: if it’s not done right, we make it right. No paperwork fights. No arguing. Dale Kessler founded this company on a rule that still names it: if the pane is not true, the job is not done.
Windows & Doors Services We Offer in San Antonio
Window Installation
New construction or a remodel in San Antonio means working to Pasco County’s wind-load maps and getting the flashing detail right on homes that see daily afternoon thunderstorms in summer. We install manufacturer lines including Andersen, ES Windows, and ECO Window Systems, with both warranty layers registered in writing.
Learn more about our Window Installation in San Antonio.

Door Installation
Front entry, French, or a patio door that has to survive ten months of humidity and two months of daily storms, a door set out of square in San Antonio will bind in July and leak in August. We set every door plumb, level, and true to the rough opening, then seal the threshold against Pasco County’s rain patterns.

Window Replacement
Whether you’re in a century-old cottage with original wood sash or a 1990s ranch with failing vinyl seals, replacements in San Antonio have to account for one of the widest housing-stock ranges in Pasco County. We’ll tell you honestly if an insert will work or if the frame needs a full tear-out before you spend a dime.

Impact Windows & Doors
Being inland off SR-52 doesn’t exempt San Antonio homes from Florida’s wind-borne debris rules, which is why we offer Impact Windows & Doors in San Antonio. We pull the Pasco County product-approval data for your address and install PGT, CGI, and ES Windows impact lines that meet the current code without over-selling you a coastal-rated unit you don’t need.

Energy-Efficient Windows
A south-facing wall of glass on a San Antonio ranch home gets brutal afternoon sun for eight months a year. Our Energy-Efficient Windows in San Antonio use Low-E coatings and proper gas-fill selection that cut that load meaningfully, and we’ll show you the exact glass packages with real performance numbers, not vague “energy saver” talk.

Sliding & Patio Doors
Frankly, a sliding door in Florida is a long-term relationship with a stainless steel track and a set of rollers. We install Sliding & Patio Doors - San Antonio that operate smooth on day one and stay smooth ten years later because the track is set level and the rollers are rated for the panel weight.

Glass Railing Systems
Lakeside and second-story decks around Lake Jovita and the newer San Antonio subdivisions call for glass railing that meets Pasco County guardrail requirements without blocking the view. We install Glass Railing Systems - San Antonio with tempered, code-compliant glass cut to your exact measurements.

Custom Windows & Doors
Some of San Antonio’s older homes don’t have a single standard opening anywhere. Custom-sized units from ES Windows, or Andersen give you a true fit in a frame that never saw a factory spec sheet. Every one gets the same two-measurement rule and written warranty registration.

Why San Antonio’s Climate & Housing Affect Windows & Doors
San Antonio is one of Florida’s earliest planned Catholic colonies, founded in 1881. That founding predates air conditioning, standard lumber dimensions, and the modern Florida Building Code by decades. The original wood-sash windows in the historic core have endured over a century of inland Pasco County humidity, which means wood rot around sills and thresholds isn’t a possibility, it’s a schedule. Original pine frames from the early 1900s are often hollowed by moisture and Formosan termite damage to the point that what looked like a straightforward insert turns into a full-frame rebuild once the trim comes off. That’s the most common surprise in San Antonio window work, and it’s one we flag on the estimate, not after the fact.
Meanwhile, the SR-52 and I-75 growth corridors are pushing tract developments into the same small footprint. Those houses need current Florida Building Code wind-rated products, proper flashing, and energy packages that keep cooling bills sane through the summer storm season. Serving both markets on the same street is the reality of this town, and it’s a scope you only learn by doing the work here. San Antonio’s inland location means slightly lower design wind speeds than the coast, but Pasco County product-approval requirements still apply to every replacement and new install. We don’t guess at those numbers; we pull the maps for your address.
Pricing for Windows & Doors in San Antonio
Window replacement in San Antonio typically runs $600 to $2,500 per opening depending on whether you’re looking at a standard insert, a full-frame tear-out, or an impact-rated unit. Entry and patio doors run $1,200 to $5,000 installed. The wide spread is because the 1905 cottage and the 2020 tract house are priced by completely different rules. Here’s a straightforward breakdown:
- Standard vinyl insert window: $600-$1,200 per opening
- Full-frame replacement (common in historic homes): $1,100-$2,500 per opening
- Impact-rated window: $1,500-$3,500 per opening
- Exterior door installation: $1,200-$4,000
- Sliding patio door install: $2,000-$5,000
We give fixed pricing on paper before work starts. No change orders, no surprise line items. The price we quote is the price you pay, and we register both warranty layers before we leave. Call (813) 320-9346 for an exact quote. Estimates are free, and we’ll tell you honestly if an insert will work or if the frame needs a tear-out.

FAQs About Windows & Doors in San Antonio
Original wood frames from the late 1800s and early 1900s in San Antonio’s historic colony core are often hollowed by moisture rot and Formosan termite damage to the point that the rough opening itself must be rebuilt. An insert needs sound framing to anchor into; when the frame is compromised, a full-frame tear-out is the only correct fix. Call (813) 320-9346 and we’ll tell you what your frames actually look like once the trim is off.
San Antonio sits in Pasco County’s inland wind zone, which has lower design wind speeds than coastal zones but still requires Florida Building Code product-approval and wind-load compliance on new construction and most replacements. Whether your specific home requires impact-rated product depends on its age, location, and exposure. We pull the current Pasco County maps for your address before recommending anything. Call us for a straight answer.
Intense UV exposure and high seasonal humidity degrade vinyl seals and weatherstripping faster here than in drier climates, and afternoon thunderstorms stress flashing and threshold details that might survive fine in a milder environment. We select and install materials specifically for Pasco County’s inland heat-and-humidity cycle. Ask us about the glass packages we most often recommend for San Antonio’s south-facing walls.
Plan on $600 to $2,500 per window opening and $1,200 to $5,000 for most door installs, with the spread driven by whether your house is a historic-era full-frame project or a modern insert job. The price we quote is the price you pay, with both warranty layers registered in writing. Call for an exact quote, and the estimate is free.
No. We quote fixed pricing in writing before work begins, and we don’t write change orders for conditions we should have caught during the estimate. In old San Antonio homes there can be hidden frame damage, which is why we inspect rough openings carefully before pricing. If we miss something, that’s on us, not your bill.

What San Antonio Customers Say
"A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G."Eleven windows replaced in two days. The crew chief, Marcus, showed me the level on every single frame before they caulked it. My wife noticed the street noise was gone before I did."
- Ronald P."Whole-house window replacement at 71 years old is not something you want to do twice. Dale walked the house himself for the quote. Crew was the same three men all four days, and the foreman knew every window by room."
- Pat and Ray L.
