Fast, Reliable Impact Windows & Doors Across San Antonio
Impact windows and doors in San Antonio, FL typically cost $900-$2,800 per opening installed, with whole-home projects on older historic cottages running higher because of the full-frame tear-out work those homes usually require. Most San Antonio jobs take one to three days once product arrives, though homes in the 1881 historic core often need extra time for rough-opening rebuilds. If you’re weighing impact protection for a wood-frame cottage near the old colony center or a newer tract home off SR-52, call us at (813) 320-9346 for a straight answer and a written estimate.
We’ve worked both ends of San Antonio’s housing stock, and that matters more here than in most Pasco County towns. The old pine frames from the early 1900s behave nothing like the 2×6 openings in a five-year-old subdivision. A crew that only knows new construction will misjudge the old work, and a crew that only does restorations will overbuild the new. We know the difference because we’ve pulled trim on both.
Why TruePane Windows & Doors Is San Antonio’s Preferred Impact Windows & Doors Company
TruePane Windows & Doors has been installing and replacing windows and doors since 2008 through a craft tradition that started with second-generation glazier Dale Kessler. We’re not a franchise crew that rotates through town. We hire local installers, train apprentices into journeymen, and show up in uniform with the truck stocked for the job. San Antonio homeowners tend to remember the contractor who left them with a fogged seal and a door that binds in July. We build our reputation on not being that contractor.
Every San Antonio job is covered by our 90-Day Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves your driveway. No paperwork fights. No arguing. If we set a pane out of true, we make it right. That’s the rule Dale Kessler keeps on the whiteboard, and it governs every install we do from the historic colony streets to the new subdivisions along the SR-52 corridor.
When you call (813) 320-9346, a live person answers. Not a voicemail tree, not a callback form. That’s true at 9 a.m. and true at midnight. People in San Antonio tend to call rather than click, and we’ve kept the phone line staffed accordingly for as long as we’ve done this work.
Key takeaways:
- Written line-item pricing before work starts, with allowances for hidden rot or framing damage spelled out in the contract
- Both manufacturer warranty layers registered in writing, durations stated, before we leave the driveway
- Background-checked, uniformed technicians who measure every opening twice
- 90-Day Done Right Promise on every job, no fine print that covers neither workmanship nor product
Our Impact Windows & Doors Services in San Antonio
We handle the full scope of Impact Windows & Doors work in San Antonio, but the three services that matter most in this market are wind mitigation and code compliance, hurricane impact windows, and impact entry and French doors. Here’s what each involves on the ground here.
Hurricane Impact Windows
Impact windows in San Antonio’s historic homes almost always require full-frame replacement. The original pine jambs and sills from the 1880s through the 1920s have spent a century absorbing humidity, and in many cases they’re hollowed by rot or Formosan termite damage. We specify impact-rated units with fusion-welded frames and argon fill, then rebuild the rough opening so the new window has a structurally sound substrate to anchor to.

Impact Sliding Glass Doors
Sliding glass doors in San Antonio take a beating from UV exposure and summer thunderstorm cycles. The seals on older units fail first, then the rollers, then the track. When we install impact sliding glass doors here, we check the threshold for rot, verify the rough opening is square, and set the door so it won’t bind in July humidity like so many mid-century ranch homes are prone to.

Impact Entry & French Doors
Entry and French doors on San Antonio’s older cottages often sit in wooden frames that have been absorbing moisture for decades. A new impact-rated door needs a solid jamb and proper flashing, or it fails at the hinge and the threshold within a few seasons. We rebuild the frame when needed, set the door true, and match the trim to the home’s original millwork profile whenever the homeowner wants to preserve the historic look.

Wind Mitigation & Code Compliance
Pasco County sits inland of the highest coastal wind zones, but San Antonio properties still must meet Florida Building Code product-approval and wind-load requirements tied to the county’s design wind speed maps. We pull permits, route the paperwork correctly, and make sure the product you buy carries the right Florida product approval for your specific address. If a home inspector needs a wind mitigation report updated after an install, we handle that coordination too.

Impact Garage Doors
Garage doors are the largest opening in most San Antonio homes and one of the most overlooked in wind mitigation. We install impact-rated garage doors with reinforced tracks and bracing systems that comply with Pasco County requirements, and we check the surrounding framing because a strong impact door in a rotted jamb is not protection.

Trusted Brands We Service in San Antonio
We’re an authorized installer for more than a dozen manufacturer lines, and for San Antonio homeowners we typically quote Andersen, Pella, and PGT impact product lines side by side on paper. That way you see exactly what you’re buying, with warranty durations stated, before you commit. We don’t steer every San Antonio job toward one brand. We quote options, then set what you choose. We keep common hardware and parts stocked for faster turnaround, and when a unique seal or track component is needed, we order it directly through the manufacturer rather than a third-party supplier.
Common Impact Windows & Doors Problems We See in San Antonio Homes
- Rot and termite hollowing of original pine frames and sills. On the 1880s-1920s cottages in the historic core, an insert impact window often has no structurally sound substrate to anchor to. We discover this once trim is pulled, and the fix is a full-frame tear-out, not a patch.
- Failed insulated glass units with fog between panes. The argon has escaped and the U-factor and SHGC are effectively at single-pane levels. We see this in homes of every age in San Antonio, but mid-century ranches with original aluminum frames are the most common culprits.
- Undersized or non-square rough openings on early wood-frame built homes. Over the years, openings have been over-cut and shimmed in ways that leave the rough sill off-level and non-structural. A code-approved impact window set into that opening will bind and leak.
- Threshold rot on doors facing the afternoon sun. San Antonio’s heavy thunderstorm season drives water against south-facing thresholds, and on older homes the sill underneath is often the first thing to fail. We replace sills when we set impact doors, not after the leak shows up inside.
Pricing for Impact Windows & Doors in San Antonio, FL
On newer-build San Antonio homes with true 2×6 openings, a standard impact window install runs $900-$1,400 per opening depending on size and product line. In the historic core, the same-sized window often runs $1,800-$2,800 per opening because the rough opening must be rebuilt before the window is set, and trim profiles have to be matched to 1920s-era millwork. Impact entry doors in San Antonio run $2,200-$4,500 installed, and impact sliding glass doors run $3,500-$7,000 depending on width and frame rebuilds. These are written ranges, not guesses. We quote the job on paper with allowances for hidden rot or framing damage written into the contract, and if something unexpected turns up, it’s priced and approved in writing before we touch it. Call (813) 320-9346 for a free estimate.

FAQs - Impact Windows & Doors in San Antonio
Yes, in most cases the opening must be rebuilt. An impact window needs a structurally sound perimeter to anchor to. On a wood-frame cottage near the old colony center, our crew pulled the interior casing on a double-hung window with a failed insulated glass unit and found the original pine jamb had turned to powder at the sill and along the side jambs. We rebuilt the rough opening, set a new impact-rated double-hung with a fusion-welded frame and argon fill, applied flashing tape at the head and sill, and matched the trim profile to the home’s 1920s-era millwork. The window wasn’t the only thing that needed replacing. The opening did too.
We pull the wind speed maps for Pasco County and check your specific address against the Florida Building Code product-approval requirements for your design wind speed. Inland San Antonio is slightly removed from the highest coastal wind zones, but product approval is still mandatory, and the correct rating depends on your exact location, roof geometry, and exposure. We handle this as part of the permit package, not as an afterthought. Call (813) 320-9346 if you want us to pull the map for your street before you buy anything.
Yes. Moisture between the panes means the insulated glass unit’s seal has failed, the argon fill has escaped, and the U-factor and SHGC are no longer performing to the rating stamped on the unit. The window is not providing the wind mitigation or the thermal protection you paid for. In San Antonio’s humidity, a failed seal also invites condensation and, eventually, mold in the frame. The unit needs replacement, not repair. Call us for a quote on the replacement and a check of the surrounding frame while we’re at it.
Sometimes, yes. When we open the walls on an older San Antonio home, we often find outdated wiring routed through the stud cavities or undersized header beams that no longer meet current code. A permit on a full-frame replacement can require bringing those conditions up to standard. We handle this by inspecting first, writing allowances into the contract, and pricing any surprise in writing before we touch it. That’s the only way to do this work without an ugly surprise at the end.
In most cases, yes. We remove trim carefully, rebuild the rough opening as needed, set the new impact unit, and reinstall or reproduce the original trim profile to match the home’s period millwork. On the old colony center homes, that often means matching 1920s-era casing profiles and corner details rather than slapping on ranch-style trim. It’s more work, and we quote it that way, but the end result is an impact-rated window that still looks like it belongs on the house.
