PGT Construction in San Antonio, TX | Mason Remodeling Co San Antonio
We provide independent PGT window and door service across San Antonio, from WinGuard impact units to Eze-Breeze porch enclosures. The thing that sets our PGT work apart here is simple: we’ve spent over a decade learning how these frames and glass behave on San Antonio’s shifting clay soils, and we plan every repair around that reality. You’ll get a written price before any work starts. Call (254) 269-5071 to schedule your free estimate.
We’re not manufacturer-affiliated or authorized by PGT. We’re an independent service provider, which means we make honest repair-versus-replace calls without a corporate script pushing one direction. That independence matters when a $75 roller replacement keeps your sliding door working for another five years. Mason Remodeling Co, a General Contractor - San Antonio, has been part of the Threshold Group family since 2004, and every technician who arrives at your door is background-checked, identity-verified, and introduced by name and photo before the visit.
If you need PGT sales & service from a crew that knows San Antonio’s quirks, you’re in the right place.
Why San Antonio Residents Choose Us for PGT Service

PGT builds windows and doors for coastal impact zones, but San Antonio throws its own curveballs: triple-digit summer heat, UV exposure that degrades seals fast, and clay soil that moves under slabs and pier-and-beam foundations alike. A PGT sliding door that worked perfectly in April can bind by August, not because of a manufacturing flaw, but because the floor beneath it shifted a quarter inch. We’ve seen it happen in Alamo Heights, Terrell Hills, and across the north side.
Isaac Pruett, our owner, learned construction fundamentals at Los Angeles Trade-Technical College and has been running jobs across Texas for years. He’s the one who reminds us that the best repair is the one you don’t have to redo. That’s why we use OEM PGT parts for critical seals and hardware whenever they’re available, and we stock common rollers, balances, and corner keys locally so San Antonio homeowners aren’t waiting on a shipping truck from Florida. Every repair carries our 365-Day Done Right Promise: if it’s not right within a year, we make it right at no cost to you.

Common PGT Construction Problems We Solve in San Antonio
- Vinyl frame distortion from extreme heat. San Antonio regularly hits 100°F in July and August, and dark-framed PGT WinGuard Vinyl windows absorb that heat. Sashes bind, corners warp, and locks stop lining up. We’ve replaced warped sashes and re-aligned frames on homes from King William to Stone Oak.
- Roller and track wear on sliding doors. Clay soil expansion and contraction shifts door frames out of square. That puts uneven pressure on rollers, which grind down fast and chew up tracks. PGT WinGuard Aluminum sliders are especially prone when the slab beneath them moves seasonally.
- IGU seal failure from UV exposure. San Antonio’s sun is relentless. The insulating glass unit seals on PGT windows degrade faster here than in cooler climates, leading to fogging between panes. We replace failed IGUs and re-seal frames to keep moisture out.
- Weep hole clogging from flash-drought dust. Dry spells kick up dust and pollen that settle in window tracks. PGT weep holes, small drainage channels at the bottom of the frame, clog up. Water backs up, seeps past the weatherstripping, and drips onto interior sills. We clean, flush, and clear these during routine service.
- Casement hinge and corner-key failures on post-tension slabs. Homes across San Antonio’s north and west sides sit on post-tension concrete slabs. When those slabs crack from soil movement, window frames rack. PGT casement corner keys, the plastic or metal connectors at frame corners, snap under the stress. We replace them with OEM parts and re-shim so the window operates true again.
PGT Service in San Antonio: What Local Conditions Mean for Your Equipment

Here’s a fact that shapes PGT work in San Antonio more than anywhere else we’ve operated: in the 1950s pier-and-beam houses of Terrell Hills and Alamo Heights, a structure can drop a full inch during one dry summer. One inch. That’s not a subtle shift, and it’s not something window manufacturers design around. When the pier-and-beam supports settle unevenly, PGT window frames rack, sashes stick, and sliding door tracks twist. A window installed square in March can be out of square by Labor Day.
What this means for PGT owners is that alignment isn’t a one-time thing. After every severe drought cycle, which San Antonio experiences with regular “flash drought” patterns, window alignment should be re-checked. We do that as part of our service. We check the reveal, the gap between sash and frame, test the lock engagement, and verify drainage. If a pier-and-beam home has settled, we adjust before the frame stress turns into broken glass or stripped hardware. In New Braunfels or Boerne, the soil behaves differently. In San Antonio, particularly the older neighborhoods east of Broadway, late August is when the most dramatic cracks appear overnight. We plan for it.
Mason Remodeling Co San Antonio works across the entire San Antonio service area, from downtown historic districts to the sprawling northern suburbs.
PGT Models & Products We Service in San Antonio
Our team services the full PGT residential lineup. That includes PGT WinGuard Vinyl and PGT WinGuard Aluminum impact windows and doors, the two most common lines in San Antonio homes built or retrofitted after the 2000s. We also work on PGT SpectraGuard, the vinyl non-impact line often found in newer construction on the far north side, and PGT Eze-Breeze, the vinyl-glazed porch enclosure system that’s popular for converting covered patios into three-season rooms.
On parts, we take a straightforward approach. For critical seals, corner keys, hinge hardware, and glass units, we use OEM PGT parts whenever they’re available. For things like rollers, balances, and aftermarket weatherstripping, we’ll tell you when a quality aftermarket part performs just as well at a lower cost. No games, no markup disguised as “upgrades.” We keep common PGT parts stocked locally so San Antonio turnaround is measured in days, not weeks.

AfterPGT Service Pricing in San Antonio

PGT window and door repairs in San Antonio vary by scope, whether you’re dealing with a single failed IGU or a full impact-window replacement for an entire elevation. Here’s what homeowners should plan for:

|---|---|
| Roof Repair | $400 – $1,800 |
| Impact Window Installation | $8,000 – $25,000 |
| Window Replacement | $4,500 – $15,000 |
A single PGT window replacement typically runs between $800 and $2,800 depending on size, impact rating, and frame material, so costs vary for any San Antonio Bathroom Remodeling project involving window updates.

What drives cost: accessibility, whether the unit is on a post-tension slab requiring special shimming, and whether we’re replacing an IGU versus a full sash. Every estimate includes a written line-item breakdown with the exact price before any work begins. Call (254) 269-5071 for your free estimate, no pressure and no verbal ballpark that changes later.

FAQs – PGT Construction in San Antonio
How does San Antonio’s clay soil affect PGT sliding door operation?
San Antonio’s expansive clay soils shrink during dry spells and swell after rain, which shifts slab foundations and pier-and-beam supports by fractions of an inch to a full inch in extreme cases. For PGT sliding doors, that means the frame goes out of square, rollers bind or wear unevenly, and the door becomes hard to open or close by late summer. We re-align the frame, replace worn rollers, and shim with composite material designed to withstand continued movement. Call (254) 269-5071 to schedule an alignment check.
Can you repair a fogged PGT WinGuard window in a Terrell Hills pier-and-beam home?
Yes, in most cases. Fogging means the insulating glass unit seal has failed, allowing moisture between the panes. On a pier-and-beam home, we also check whether foundation movement has stressed the frame enough to contribute to the seal failure. We replace the IGU, address any frame racking with proper shims, and reset the window so it operates correctly. The repair usually takes one visit, and we’ll confirm pricing before we start.
What impact rating is needed for PGT windows in San Antonio?
San Antonio sits inland, so it’s not in a hurricane wind-borne debris zone like Houston or Corpus Christi. Most San Antonio homes do not require impact-rated glazing by code, but many homeowners choose PGT WinGuard anyway for storm protection, UV reduction, and noise control. The decision comes down to your insurance requirements, your neighborhood, and whether you’re on a post-tension slab where frame racking is a concern. We’ll walk you through the options without upselling.
Do you use non-OEM parts for PGT repairs, and is that safe?
We use OEM PGT parts for critical components like seals, corner keys, hinge hardware, and glass units. For consumable parts like rollers and balances, a quality aftermarket replacement often performs as well as OEM at a lower cost, and we’ll tell you when that’s the case. We never install a part that compromises the window’s function or safety. The choice is yours, with honesty from us about what’s worth the OEM price.
How does the San Antonio ‘flash drought’ pattern affect PGT window weep holes?
Flash droughts dry out the soil fast and kick up fine dust and pollen that settle in window tracks. PGT weep holes, the small drainage channels at the base of the frame, clog with that debris. When they clog, water that should drain outside backs up and leaks onto interior sills. We flush weep holes, clean tracks, and test drainage as part of regular PGT service. If you’ve noticed water pooling on your sill after rain, call (254) 269-5071 and we’ll clear it before it damages drywall or flooring.
