Why San Antonio Homeowners Choose TruePane Windows & Doors
San Antonio homeowners tend to stay put. They have lived in the same house for twenty, thirty, sometimes forty years. They remember the contractor who hung a door that bound by July and replaced a window that fogged by spring. They are not shopping for the cheapest bid in town. They are looking for the last call they should have to make. That is who we work for.
We install, replace, and service windows and doors throughout San Antonio, including King William and Monte Vista, where the housing stock demands more than a catalog order. Dale Kessler built the company in 2008 on a whiteboard rule that still governs every job: if the pane is not true, the job is not done. Every install carries the Done Right Promise and The Keystone Standard. Both manufacturer warranty layers get registered in writing, with durations stated, before our truck leaves your driveway. No paperwork fights. No arguing about what the fine print covers. We stand behind it.
Windows & Doors Services We Offer in San Antonio
Window Installation
New-construction and retrofit window installation for San Antonio homes, from double-hung to casement to picture units. Our technicians measure every opening twice, and on older homes in the 78204 and 78201 areas, we account for out-of-square framing before the window ever ships.
Learn more about our Window Installation in San Antonio.
Door Installation
Entry doors, French doors, and transom-lit doors installed square, sealed properly against San Antonio’s heat and humidity, and checked for smooth operation before we leave. On older homes with non-standard rough openings, we quote custom sizing rather than forcing a catalog door into a hole it was never meant to fit.
Learn more about our Door Installation in San Antonio.
Window Replacement
Full-frame and insert replacement for fogged seals, broken sashes, and drafts. San Antonio’s heat breaks down low-quality seals in a few years, so we quote manufacturer lines side by side on paper so you see exactly what you are buying and what the warranty actually covers.

Impact Windows & Doors
Rated impact units from manufacturers including PGT and CGI, installed to code and backed by written warranty registration. San Antonio’s position on the Balcones Escarpment means severe weather is a real design factor, not a sales pitch.
Learn more about our home page or call for a free estimate.
Energy-Efficient Windows
Dual-pane and triple-pane units with low-E coatings and argon fill, sized for San Antonio’s dual demand: keeping out summer heat and retaining heat during the arctic intrusions the city now expects. We quote thermal performance in writing before you commit to a single unit.
Call (888) 635-0804 for a side-by-side comparison of efficiency ratings.
Sliding & Patio Doors
Sliding glass doors and patio doors that roll true and seal tight, installed in homes across San Antonio where seasonal clay movement can shift header alignment. We shim, level, and adjust so the door performs the day it is installed and stays that way.
Call (888) 635-0804 to schedule a free estimate on patio door work.
Glass Railing Systems
Custom glass railing systems for balconies, terraces, and pool enclosures in San Antonio. We install tempered glass panels with hardware that holds up to UV exposure and thermal cycling without loosening or hazing over time.
Call (888) 635-0804 to discuss a glass railing project.
Custom Windows & Doors
Non-standard openings, arched tops, transom-lit doorways, and period-sensitive reproductions for San Antonio’s older homes. We mill, size, and quote custom work as a standard practice on houses where a catalog unit simply will not fit.
Call (888) 635-0804 for a custom quote with dimensions confirmed on site.

Why San Antonio’s Climate & Housing Affect Windows & Doors
The 78201 through 78210 corridor holds several of San Antonio’s densest certified historic districts. In King William, Monte Vista, Government Hill, and Lavaca, any window or door replacement typically requires a Certificate of Appropriateness from San Antonio’s Office of Historic Preservation before work can legally proceed. That approval layer is routine here, and we handle it as a standard part of the job, not an afterthought.
But the same neighborhoods sit on the Balcones Fault Zone’s expansive black-clay soils, which continuously rack door frames and bind window sashes as the ground heaves and settles seasonally. We regularly see frames installed perfectly plumb drift 1/4 to 3/8 inch out of square within a few years. That means doors that closed smoothly at installation begin dragging or swinging open on their own. Experienced San Antonio contractors quote trim-back and re-shimming as an expected return visit, not a warranty defect. When you work with TruePane, that reality is built into the quote, not discovered after the fact.
Pricing for Windows & Doors in San Antonio
Window and door pricing in San Antonio depends on the house, the opening, and the product line, and we quote line items rather than lump sums. Here is what homeowners can generally expect:
- Window replacement (insert, standard double-hung): $550-$950 per window installed
- Full-frame window replacement: $850-$1,400 per window installed

- Sliding patio door replacement: $2,200-$4,500 installed
- Custom or historic-matched windows/doors: Quoted per opening after site measurement
Every quote is a square deal. Upfront pricing, no surprise line items, no change orders hiding in the fine print. Call (888) 635-0804 for a free estimate and a side-by-side comparison of manufacturer lines on paper.

Yes, in most cases. San Antonio’s Office of Historic Preservation requires a Certificate of Appropriateness for window and door replacement in the city’s certified historic districts, including King William (78204), Monte Vista (78201), Government Hill (78208), and Lavaca (78210).

Call (888) 635-0804 for a consultation.

What San Antonio Customers Say
"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."Two entry doors. Showed up when they said, second day was a half day like they said, and the painter they recommended confirmed the frames were dead plumb. The financing was explained in actual dollars, not a brochure."
- Janet R."Impact windows on the whole house. They handled the permit, the inspection, and gave me a folder with every approval number for the insurance company. My windstorm premium dropped enough to notice."
- Bill T.
