Windows & Doors Services in Saint Hedwig, TX
Saint Hedwig sits on Bexar County’s Blackland Prairie, where the clay soil shrinks and heaves with every dry summer and wet winter. That movement works on window frames and door jambs year after year, and the older ranch homes across the 78152 ZIP show it. If you’re looking at a door that won’t latch or a window that’s gone foggy between the panes, you don’t need a pitch, you need somebody who’s seen it before and can fix it right. TruePane Windows & Doors serves Saint Hedwig with background-checked, uniformed crews who measure every opening twice and stand behind the work in writing. Call (888) 635-0804 and a live person answers, day or night.

Why Saint Hedwig Homeowners Choose TruePane Windows & Doors
Dale Kessler founded TruePane in 2008 with a rule he still keeps on the whiteboard: if the pane is not true, the job is not done. That’s why homeowners off St. Hedwig Road and along Kilowatt Road call us when the guesswork has already cost them once. We don’t send a salesperson with a binder. We send a technician who checks the jamb, levels the rough opening, and writes out a line-item quote on paper before any work is ordered. In neighborhoods like the older acreage lots south of FM 1518 and the newer infill streets east toward Adkins, that difference shows up fast. The Keystone Standard means both manufacturer warranty layers get registered in writing before our truck leaves your driveway, and the Done Right Promise backs the workmanship with no paperwork fights. We carry the same quiet certainty our customers expect, and we answer the phone like a local company should.
Windows & Doors Services We Offer in Saint Hedwig
Window Installation
New windows in Saint Hedwig have to hold up to 100-degree summers and the constant ground movement under older slabs. We set frames square, flash them properly, and register the warranty on the spot. Learn more about our Window Installation in Saint Hedwig.

Door Installation
A door that binds in July is usually a frame issue, not a hinge issue. We level and shim the jamb before we hang anything, so the door closes true the first time. Learn more about our Door Installation in Saint Hedwig.

Window Replacement
Failed seals on aluminum-frame windows from the 1970s and 1980s are common across the 78152 ZIP. We replace them with units sized to the actual opening, not the hole the old window left behind. Learn more about our Window Replacement in Saint Hedwig.

Impact Windows & Doors
Saint Hedwig doesn’t sit on the coast, but severe weather and wind-driven debris still put windows and door glass at risk. We install impact-rated units from manufacturers like CGI and PGT that meet Miami-Dade standards and carry documented warranties.

Energy-Efficient Windows
South Texas UV breaks down vinyl seals and caulk lines within a few years. Low-E glass and proper installation keep the heat on the outside where it belongs and drop the load on your air conditioner from June through September.

Sliding & Patio Doors
Clay-soil movement pulls patio door tracks out of alignment and leaves rollers grinding. We square the rough opening, set the track level, and adjust the panels so they glide instead of fight.

Glass Railing Systems
For porches, decks, and walkouts across Saint Hedwig, tempered glass railing keeps sightlines clear without rusting or rotting. We measure, fabricate, and install systems built to code.

Custom Windows & Doors
Older ranch homes often have odd-sized openings that no stock unit fits. We order custom-fabricated windows and doors to match the actual measurements, including arch tops and tall transoms.

Why Saint Hedwig’s Climate & Housing Affect Windows & Doors
Two things shape nearly every window and door job here: the soil and the sun. Saint Hedwig sits on expansive Blackland Prairie clay that shrinks in drought and swells after rain. When a dry San Antonio summer pulls the moisture out of that clay, slabs drop at the corners and door jambs rack out of plumb. A door that latched fine in May suddenly misses the strike plate by a quarter inch in August. We carry levels and shims on every truck because quoting a door replacement without checking the jamb first means a callback, and we don’t set ourselves up for callbacks. On the window side, the 1960s through 1980s ranch stock across the 78152 ZIP still carries single-pane aluminum frames that baked under decades of UV. Add the February 2021 freeze that cracked glazing seals across Bexar County, and a lot of Saint Hedwig homes are still living with fogged glass and drafty door bottoms.

FAQs About Windows & Doors in Saint Hedwig
Window replacement in Saint Hedwig typically runs $450 to $900 per vinyl double-pane window installed, with impact-rated units starting around $900 per window. The final number depends on the condition of the rough opening, whether the frame needs shimming or reframing, and the manufacturer line you choose. Call (888) 635-0804 for an exact quote, estimates are free.
The clay soil under Saint Hedwig shrinks during summer drought, which drops one corner of the slab and pulls the door jamb out of square. The fix is usually a level check of the jamb, shimming behind the hinges, and re-aligning the strike plate, not a new door.
If the frame is still square and in good condition, we can often replace just the insulated glass unit, or IGU. But on older aluminum frames from the 1970s and 1980s, the frame corners are frequently failed too, and a full window replacement makes more sense long-term. We’ll show you both options on paper before you decide.
When the scope of work in Saint Hedwig requires a permit, we handle it. We pull the permit, schedule the inspection, and make sure the job passes. That’s part of the square deal, not an upgrade.
No. The quote we hand you is the price on the bill, unless we uncover something hidden behind the drywall or sheathing that changes the scope. If that happens, we stop, show you what we found in writing, and get your approval before we proceed. No surprise line items. Call (888) 635-0804 if you’ve been burned before and want to see the difference.

What Saint Hedwig Customers Say
"A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G."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."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.
