Windows & Doors Services in San Antonio, FL
San Antonio sits at a crossroads of Florida history. The town was founded by Belgian Catholic immigrants in 1881, and many of the wood-frame homes near the old church and the historic core still carry original single-pane windows in rough openings that were never built to a modern standard. That means window and door work here is not a matter of swapping like for like. It is measured, fitted, and made true to the opening. TruePane Windows & Doors serves homeowners across San Antonio and the surrounding countryside in Pasco County. When you call (754) 238-2201, a live person answers, and we schedule a time to measure and quote the work in writing.

Why San Antonio Homeowners Choose TruePane Windows & Doors
We have learned that the homeowners who call us from San Antonio are not shopping for the lowest number on a bid sheet. They are looking for the last call they will have to make on a window or a door. Dale Kessler founded this company on a rule that still sits on the whiteboard in the shop: if the pane is not true, the job is not done. That standard governs every install we do, from a side door in Trilby to a full window replacement near the San Antonio town center.
Our crews work regularly in neighborhoods around Curley Road, Pump Station Road, and the older streets just off State Road 52, where homes tend to be older and openings tend to be irregular. In those blocks, we see what happens when a previous installer measured once and guessed the rest. We measure twice, quote the manufacturer lines side by side on paper, and register both warranty layers in writing before the truck leaves the driveway. That is The Keystone Standard, and every TruePane job in San Antonio carries it, plus the Done Right Promise. If it is not done right, we make it right, no paperwork and no arguing.
We are an authorized installer for manufacturer lines including PGT, CGI, and Ply Gem, which matters if you are in a Pasco County area where wind-load ratings and product approvals get checked at inspection. A background-checked, uniformed technician shows up when we say, does the work as if it were his own mother’s house, and leaves the opening sealed tight and square.

New construction and retrofit window installation for San Antonio homes, old or new. We set every window in a prepared, squared rough opening, flash it properly for Florida humidity, and trim it out clean.
Learn more about our Window Installation in San Antonio.

Learn more about our Door Installation in San Antonio.

Window Replacement
When an old single-pane unit has failed, we remove it carefully, modify the rough opening if the framing demands it, and install a modern, energy-rated replacement that meets current Florida Building Code. We haul the old sash and glass away.

Impact Windows & Doors
Many San Antonio homes sit in a wind zone that requires either impact-rated glazing or an approved shutter system to pass inspection. We supply and install Impact Windows & Doors in San Antonio from manufacturers like PGT and CGI, with product approvals in hand.
Contact us for impact window and door details specific to your San Antonio property.

Energy-Efficient Windows
Low-E glass, argon fill, and tight weather sealing cut the relentless Central Florida heat that pours through old single panes. We quote Energy-Efficient Windows in San Antonio so you see the glass package and the U-factor before you commit.
Contact us about energy-efficient windows for your San Antonio home.

Sliding & Patio Doors
Sliding doors take a beating from daily thermal cycling and soil movement here. We replace worn rollers, straighten out-of-true tracks, or install a new Sliding & Patio Doors - San Antonio unit that glides without fighting.
Contact us for sliding and patio door work in San Antonio.

Glass Railing Systems
For porches, decks, and pool surrounds, we install Glass Railing Systems - San Antonio that meet code and hold their line. The hardware is stainless, the glass is tempered, and the posts are set plumb.
Contact us about glass railing systems in San Antonio.

Custom Windows & Doors
Non-standard rough openings are common in San Antonio’s older homes, and box-store sizes rarely fit. We order custom units to the actual measured opening and install them without butchering the framing.

Neighborhoods We Serve in San Antonio
We work throughout San Antonio and the rural parcels around it, and each area has its own dominant housing type. Older wood-frame homes near the historic town center, small acreage parcels off Curley Road, and newer construction closer to SR 52 all get the same approach: measure, quote, install true.
- Historic San Antonio town center - pre-WWII wood-frame homes, non-standard openings
- Curley Road corridor - mixed older cottages and ranch homes
- Pump Station Road area - rural parcels, manufactured and site-built homes
- SR 52 east side - 1980s-2000s ranch and frame construction
Most San Antonio jobs can be scheduled for an estimate within a few business days. We do not overbook, and we do not send a salesperson to pitch you a boardroom. You get a technician who measures and quotes.
Why San Antonio’s Climate & Housing Affect Windows & Doors
San Antonio was founded in 1881, and the oldest homes near the Catholic church and the historic town center still carry original single-pane windows in rough openings that were framed by hand before modern lumber dimensions existed. It is common on those blocks to find an opening that runs one to three inches off in both width and height, which means a standard replacement unit will not seat properly without careful rough-opening modification. A younger crew that has only worked in brand-new neighborhoods south toward Wesley Chapel may not expect that. We do. We see the same framed openings every week and we measure for them accordingly.
Inland Pasco’s climate makes matters harder. Intense Central Florida UV exposure degrades vinyl frames and breaks down glazing seals faster than most homeowners anticipate, while daily summer thermal cycling against high humidity stresses every seal and gasket in the envelope. Even homes far from the coast in San Antonio must meet Pasco County wind-load ratings, and non-impact windows still require an approved shutter or protection system to pass a real inspection. We quote and install to that standard, not to a coastal brochure.
Pricing for Windows & Doors in San Antonio
Pricing in San Antonio depends on what the opening actually measures and what the house needs to meet Pasco County code. We quote line-item and in writing, so there are no mysterious additions on the final bill. Here are honest ranges based on what we see in this area:
- Single window replacement (retrofit): $700-$1,400 installed, more for rough-opening modification on older San Antonio homes
- Impact window (PGT or CGI): $1,100-$2,200 per opening, depending on size and product approval
- Entry door replacement: $1,500-$3,500 installed, including new jamb and hardware
- Sliding patio door: $2,200-$4,500 installed, impact-rated units at the higher end
- Glass railing system: $180-$320 per linear foot, materials and installation
These are not bid-sheet teasers. The written estimate you get from TruePane is the price you pay unless the framing reveals something we agree to change together first. Call (754) 238-2201 for an exact quote on your San Antonio home. Estimates are free.

FAQs About Windows & Doors in San Antonio
Most window replacements in San Antonio run $700 to $1,400 per opening for a standard retrofit, with older wood-frame homes near the historic town center often requiring rough-opening modification that adds labor. Impact-rated units from PGT or CGI start around $1,100 per opening. Call (754) 238-2201 for a written, line-item quote on your specific house.
Yes, in most cases. Pasco County has a designated wind speed zone that applies to San Antonio even though the town sits well inland. Non-impact windows must be paired with an approved shutter or protection system to pass inspection. We quote both paths and let you decide with the numbers on paper.
Not on a TruePane job. We quote from actual measurements, including what we expect to find in the rough opening. If the framing reveals hidden rot or a non-standard opening we could not see until removal, we stop, show you exactly what we found, and agree on any change before we proceed. No surprise line items.
Yes. Permitting for window and door replacement in Pasco County is part of the job when required, and we handle it. Inspections are scheduled and passed before we call the job done. That is the standard, not an extra.
Most single openings are completed in one visit, typically a half to full day depending on the framing condition. A whole-house window replacement in an older San Antonio home usually runs two to four days. Call (754) 238-2201 and we will give you a straight time estimate for your house.

What San Antonio Customers Say
"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."Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
- Gene A."French doors to the patio, custom size because this house was built in 1961 and nothing is standard. Measured twice, three weeks to fabricate like they warned, and the install day they laid runners over my floors without being asked."
- Marie S.
