Custom Windows & Doors in San Antonio - Free In-Home Measure, Written Price

Fast, Reliable Custom Windows & Doors Across San Antonio

Custom window and door work in San Antonio, FL runs $900-$6,500 per opening depending on whether we’re rebuilding a rotted 1900s rough opening or setting a factory-fabricated oversized panel in new construction. Most custom shape windows and divided-light replacements take 2-5 weeks from final measure to install, and every job starts with an inspection before an estimate, not after. We’ve worked the old-town core near Curley Road and the newer subdivisions pushing in along SR-52 long enough to know that the real cost of custom work here gets discovered when the trim comes off.

Why TruePane Windows & Doors Is San Antonio’s Preferred Custom Windows & Doors Company

TruePane has been doing custom window and door work in Florida since 2008, and founder Dale Kessler built the company in 2008 around a rule that still governs every San Antonio job: if the pane is not true, the job is not done. That means we don’t set a window into a rotted opening and call it finished. We rebuild the opening, flash it correctly, and register both warranty layers in writing before the truck leaves your driveway.

San Antonio homeowners keep calling us for a reason that isn’t about price. It’s about the estimate being honest. When we quote an insert window in the historic core and the trim comes off to reveal termite-hollowed jambs, our number doesn’t quietly double. We priced the allowance up front, and any change gets approved in writing before we touch framing. That’s the kind of local reputation you earn over decades, not with a marketing campaign.

Our background-checked, uniformed technicians measure every opening twice. Dale’s 90-Day Done Right Promise covers the workmanship, and The Keystone Standard registers both manufacturer warranty layers in writing, durations stated, on every single job. When a San Antonio customer calls with a question after the install, a live person picks up: not a voicemail tree, not a callback form. That matters in a town where the contractor who fogged your neighbor’s picture window stopped answering the phone two years ago.

We serve San Antonio locally, with scheduling and dispatch coordinated from our South FL office. The crews you’ll see pulling up near Lake Jovita or down by the old colony center are the same ones who’ll answer for the work in five, ten, or twenty years. That’s the point.

Our Custom Windows & Doors Services in San Antonio

Custom Shape Windows

Arched, round, trapezoid, eyebrow, pentagon. San Antonio’s older homes often have original shaped windows that don’t match anything you can order off a stock list, and the newer custom builds going up off SR-52 frequently spec shapes the production builders won’t touch. We order to the actual rough opening after verifying it’s square and structurally sound, because a custom-shaped unit set into an out-of-square frame stresses the seal and leaks within a season or two. We fabricate through ES Windows, Andersen, and other lines we’re authorized to install, and we provide side-by-side quotes on paper so you see exactly what you’re buying.

Architectural Grilles & SDLs

If you own a 1920s cottage in San Antonio’s historic center and want the divided-light look without losing thermal performance, simulated divided lites (SDLs) with a spacer bar between the glass are the answer. These match the authentic muntin proportions of original wood sashes while giving you a low-E insulated glass unit that won’t warp in Pasco County humidity. We match true divided light patterns as closely as the modern performance standard allows, and we’ll show you samples before you commit.

Oversized Glass Panels

Floor-to-ceiling fixed panels, wide sliding door openings, and picture windows that span eight feet or more are becoming standard in the newer San Antonio homes along the SR-52 growth corridor. These are not simple product swaps. Pasco County wind-load requirements and header sizing determine whether the wall above the opening will carry the load, and we verify both before ordering glass. When an existing opening was enlarged by a previous contractor without reinforcing the header, we address that first. The manufacturers we use for oversized work include ECO Window Systems, selected for the specific wind-load rating the opening demands.

Trusted Brands We Service in San Antonio

We’re an authorized installer for more than a dozen manufacturer lines, and for San Antonio customers we lean heavily on products that hold up in this climate: ES Windows, Andersen, and ECO Window Systems among them. We stock common replacement parts and hardware for these brands locally, which means a failed roller, a worn balance, or a fogged insulated glass unit on a San Antonio home doesn’t sit waiting for a backorder from the manufacturer. When you call, we can tell you over the phone whether the part is on our truck or a day out. That’s the difference between a window company and a parts distributor; we’re the first one.

Common Custom Windows & Doors Problems We See in San Antonio Homes

• Insert windows set over rotted original sills and jambs. This is the failure we see most in the old-town core. A previous contractor dropped an insert unit into an early-1900s pine frame, screwed the trim back on, and trapped moisture and termite damage behind new casing. The homeowner doesn’t know until the window starts binding or the drywall stains below the sill.
• Custom-shaped windows ordered before the rough opening was checked. When an arched or radius unit arrives and the existing opening is out of square by half an inch, the installer either forces it or shims it into seal stress. In San Antonio’s humidity, a stressed seal fogs within two years. We measure the framing before we order the unit, not after.
• Oversized openings cut without verifying header size or wall bracing. In the newer subdivisions going up along SR-52, we regularly see openings that were widened for wide sliding doors or picture panels on the assumption the wall would hold. Pasco County wind uplift doesn’t care about assumptions. We check the header, the point loads, and the lateral bracing before any glass is quoted.
• Divided-light replacements that lost the historic proportion. Older San Antonio houses have specific muntin widths and sash proportions. Swapping in a standard SDL with the wrong bar width changes how the whole facade reads. We match the proportions of the original window, not the nearest stock option.
