Fast, Reliable Window Replacement Across Atascosa
Window replacement in Atascosa, TX usually costs between $450 and $1,100 per window for insert replacements, while full frame replacements on older ranch homes here typically run $900 to $2,400 per opening depending on framing condition and glass package. Most jobs take one to three days once the Bexar County permit clears, which adds roughly a week to the timeline compared to what San Antonio homeowners are used to. Our crews know the 78002 housing stock well and we’ll walk the job with you before you sign anything. Call (888) 635-0804 to schedule a free estimate.
If you live off Lone Star Road, FM 2790, or in the older ranch tracts west of I-35, you already know the summers punish single-pane aluminum. We’ve been pulling those frames out of Atascosa homes long enough to know what’s behind them before we open the wall. That’s the difference between a quote that holds and one that changes on day two.
Why TruePane Windows & Doors Is Atascosa’s Preferred Window Replacement Company
TruePane Windows & Doors was founded in 2008 by second-generation glazier Dale Kessler. The company carries years of craft heritage through Dale’s family trade, and our technicians treat every Atascosa install like it’s the job we’ll be judged by for the next thirty years. Homeowners in 78002 call us because we show up when we say, write the permit reality into the contract, and register both warranty layers before the truck leaves the driveway.
We’re not the cheapest bid. We’re the last call. The one you make after a fogged seal and a door that binds every July finally push you to fix it properly. Our customers in Atascosa tend to be people who’ve lived in their homes twenty-plus years and plan to stay. They want the job done right the first time, by a company that’ll still answer the phone if something moves out of square next season. A live person answers our line 24 hours a day, 7 days a week. No voicemail tree, no regional call center, no callback form. You call, someone answers.
Every technician is background-checked and uniformed. We measure every opening twice. We quote manufacturer lines side by side on paper so you see exactly what you’re buying. And every job carries the Done Right Promise backed by The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before we pull off the driveway. If the pane is not true, the job is not done.
Our Window Replacement Services in Atascosa
Insert Window Replacement
For Atascosa homes where the existing frames are still square and the rough opening is sound, insert replacement is the most cost-effective path. New sashes and insulated glass units drop into the existing jambs. But here’s what matters in 78002 specifically: the Vertisol clay under this part of south Bexar County doesn’t sit still. It shrinks in drought and swells after rain, and that movement racks frames out of plumb. Before we ever order a single insert unit, we check every opening with a level and a square. If a jamb is out by more than an eighth of an inch, we write the re-shim work into the contract as a $0 allowance line rather than surprising you with a change order. Inserts in Atascosa run $450 to $1,100 per window installed, glass package and brand dependent.

Full Frame Replacement
When the original aluminum frames have corroded at the sash corners, or the header above the window is undersized, inserts won’t fix the problem. You need the entire unit pulled, the opening inspected, and new framing set properly. Full frame replacement in Atascosa runs $900 to $2,400 per opening. The range is wide because we don’t know what’s behind the drywall until we open it. On a ranch home off Lone Star Road, our crew pulled original aluminum single-pane windows and found the framing so racked by clay heave that the new Andersen double-hungs wouldn’t seat square. We shimmed the jambs, re-flashed the openings with flashing tape, and reset the units, then drilled the side jambs and hung the sashes before any finish trim went up, so the homeowner could see the fix approved before we closed the wall. That’s how full frame work should be done out here. It’s also why our Window Replacement quotes always carry a framing repair allowance, never a vague “we’ll see” note.

Storm Window Replacement
South Texas storms don’t give much warning, and open ranchland east of Atascosa means wind-driven rain hits west-facing windows hard. Storm window replacement here means impact-rated units that meet Texas Windstorm code for the region, typically PGT or CGI lines when homeowners want certified protection. These run $1,200 to $3,000 per opening installed, depending on size and product line. For older homes where replacing every window isn’t in the budget this year, we also handle exterior storm panels and secondary glazing as a stopgap that still beats aluminum single-pane.

Energy-Efficient Upgrade
The single biggest performance upgrade for an Atascosa ranch home is pulling out aluminum single-pane and going to double-pane low-E with argon. Open-terrain sun with no tree canopy bake west-facing glass from about 1:00 PM on, and original aluminum frames have no thermal break, so they condense and corrode at the corners. We specify U-factor and SHGC per elevation, not one package for the whole house. A west-facing opening on an exposed Atascosa lot wants an SHGC around 0.22 to 0.25 and a U-factor of 0.30 or lower. East and north elevations can run different glass. These upgrades typically run $550 to $1,400 per window for inserts and $950 to $2,200 for full frame, depending on the package. The payback on the energy bill is real, but what our customers notice first is that the room stops baking by 4:00 PM.

Trusted Brands We Service in Atascosa
TruePane is an authorized installer for more than a dozen manufacturer lines, including PGT, CGI, and ES Windows. When an Atascosa homeowner wants impact-rated glass that’ll carry a Texas coast wind certification, we quote PGT and CGI side by side on paper so the product differences are clear. For homeowners who want a crisp, narrow-profile aluminum or thermally broken frame, ES Windows is a line we install regularly. We order direct from the manufacturer for every project, so there’s no warehouse middle step adding weeks to your lead time. Both warranty layers get registered in writing before we leave the driveway. That’s The Keystone Standard, and it’s not optional.
Common Window Replacement Problems We See in Atascosa Homes
- Racked frames from shrink-swell clay soil. The Vertisol clays under south Bexar County expand and contract with moisture, and over a decade or two they put window jambs visibly out of square. Insert replacements bind within a season unless the opening is re-shimmed first. We check for this on every job before ordering glass.
- Aluminum frames with no thermal break condensing and corroding. Open-terrain heat bakes original aluminum frames relentlessly, and the temperature differential across the metal creates condensation inside the track. Seal failure follows, argon escapes, and the fog forms between panes. By the time a homeowner sees fog, the sash corners are usually pitted too.
- County permit inspections flagging undersized headers and missing flashing. Bexar County inspectors on older Atascosa ranch homes routinely find header spans that don’t meet current code and flashing that was never installed correctly. If those items aren’t written into the contract as allowances, the change orders stall the job mid-wall. We write them in upfront.
- West-facing glass heat gain with no shade. With no urban tree canopy and long open sightlines, west-facing windows on Atascosa lots take brutal afternoon sun. A single-pane aluminum window on that elevation can add several degrees to the room by evening. Proper SHGC spec on the replacement glass is the fix, and it costs the same as guessing wrong.

Here are the numbers our Atascosa estimates generally land in. Insert window replacement runs $450 to $1,100 per window. Full frame replacement runs $900 to $2,400 per opening.

These ranges include labor, materials, flashing, and the Bexar County permit application.

FAQs - Window Replacement in Atascosa
A Bexar County window replacement permit typically adds five to ten business days to your Atascosa project. Because Atascosa is unincorporated, all permits run through Bexar County rather than a city building department. The county reviews the application, schedules inspections, and has a slower cadence than San Antonio’s municipal counter. We file the permit the day you sign the contract, and we build that week into the schedule from the start. If the inspection passes the first time, which it usually does when we handle the install, the job closes out clean. Call (888) 635-0804 and we’ll walk you through the exact timeline for your address.
Because the clay under your house moves, and we don’t know if your jambs are square until we put a level on them. A $0 allowance means the contract recognizes framing repair as likely work, but you don’t pay anything for it unless we actually find a problem and show you the measurements. When we find racked jambs, we shim them back to square, write the actual cost as a change order, and get your signature before doing the work. That keeps the job honest and keeps the install from binding a year later. If you want a quote with the allowance structured this way, call (888) 635-0804.
That depends on the condition of the aluminum. If the frames are square, the tracks are clean, and there’s no corrosion at the corners, sash replacement can work and saves you money. If the metal is pitted, condensing, or out of square from soil movement, full frame is the only fix that’ll last. We’ll tell you straight which one your house needs, and we’ll show you the level readings to prove it. Call (888) 635-0804 for a free assessment.
For west-facing glass on an unshaded Atascosa lot, we specify a U-factor of 0.30 or lower and a solar heat gain coefficient (SHGC) between 0.22 and 0.25. That combination rejects the most afternoon solar gain while still letting in visible light. East and north elevations can carry different specs, but the west side is where the heat comes through, and this is the fix. We quote glass packages side by side on paper so you can see the performance numbers before you buy. Call (888) 635-0804 and we’ll spec your home elevation by elevation.
No. A window replacement permit in Bexar County does not trigger a wiring upgrade. What county inspectors do flag is structural: undersized headers, missing flashing, improper shimming, and openings that don’t meet current code. Electrical work is a separate permit entirely, and county inspectors won’t require you to rewire anything just because you’re replacing a window. If an inspector does flag a structural item, it’s because the existing framing genuinely doesn’t meet code, not because the permit triggers a scope expansion. Call (888) 635-0804 if you have questions about what a permit will or won’t require on your specific house.
