PGT Construction in Upland, CA | Workshop Contractors
We provide independent PGT window and door construction service across Upland, from reframing rough openings to full impact window replacement. What makes our PGT work different here is that we solve the wall opening *and* the surrounding grading together, because Upland’s foothill lots punish any contractor who treats them as separate problems. If you need PGT service on a home in 91784, 91785, or 91786, call (844) 384-3361 for a free estimate.
Workshop Contractors is a licensed general contractor, not a PGT dealer. We’re independent: no manufacturer affiliation, no warranty endorsement from PGT. What we bring is years of hands-on PGT installation and service across Upland’s tract homes and custom foothill ranches, plus a full construction scope that includes PGT sales & service alongside roofing, siding, and structural work. When a window fails because the framing behind it moved, we fix both.
Why Upland Residents Choose Us for PGT Service
PGT windows and doors are common on Upland homes for a reason: impact-rated units hold up to Santa Ana wind events and the hot, dry summers better than off-brand alternatives. But they age differently here than they do in flatland suburbs. Homes in the 91784 foothill pocket sit on expansive clay, and the same soil that shifts a foundation also racks a window opening. A PGT sliding door that won’t track on a 1970s tract home near downtown is rarely just a roller issue, it’s usually the rough opening moving underneath it.
Our team is led by Noel Figueroa, who grew up in the Vineyard neighborhood of Ontario and learned construction at Chaffey College before spending decades working across the Inland Empire. He’s the one who taught us to check the opening before blaming the window. That’s the level of attention Upland PGT owners get from us. We’re part of the broader Upland service area we’ve served for years, and we know which PGT series were installed during which era of local building.

Common PGT Construction Problems We Solve in Upland
- Corner and sill seal failures on PGT vinyl sashes. After years of thermal cycling, the hot Upland summers followed by cool mountain nights break down the sealant at the sash corners. We see this most on west-facing walls in 91784, where afternoon sun hits the windows hard and Santa Ana wind pushes rain into any gap. The fix is new PGT-compatible glazing and gaskets, not a tube of caulk.
- Aluminum PGT frame oxidation and pitting. South- and west-facing elevations in Upland take wind-driven grit and relentless UV. The aluminum PGT Series frames on those exposures develop pitting, especially near the sill, and the gaskets dry out and crack. We repair or re-glaze when the frame is sound, and tell you straight when it’s time to replace.
- Water intrusion behind PGT units on older homes. A 1960s tract home near downtown Upland was flashed to the drainage standards of its time, which are not today’s standards. When winter rains hit, water finds the path behind the PGT frame and into the wall. We reframe, re-flash, and seal the opening so the unit sits properly in the wall.
- Sliding-door roller and track wear from foundation movement. Expansive clay under much of Upland expands and contracts with moisture. Over decades, that movement racks door openings, so PGT patio doors stop sealing and the rollers bind. We fix the track, replace the rollers, and often adjust the framing so the door works again.
- Fogged glass on impact units. The seal between the panes of an impact-rated PGT window or door can fail after years of Upland’s temperature swings, leaving condensation between the panes. Re-glazing is possible on many units, and we’ll tell you when the cost of a new sash makes more sense than repairing the old one.
PGT Service in Upland: What Local Conditions Mean for Your Equipment
Here’s the thing about PGT windows and doors on Upland’s north-side foothill streets in 91784: the windows don’t fail in isolation. These homes back up to the San Gabriel Mountains, they sit on expansive clay and steep grades, and after a heavy winter rain season, the ground around the foundation moves. When that happens, the exterior wall opening shifts, the flashing details that were barely adequate in 1975 let go, and the PGT unit that looked fine in October is leaking by March. Any contractor who shows up with just a tube of sealant is missing the actual problem. We frequently pair PGT window and door replacement with drainage correction and retaining-wall regrading on those canyon-adjacent lots, because the wall opening and the exterior grade have to be solved as one system. Build it right the first time. The second time costs twice as much and nobody’s happy about it.
PGT Models & Products We Service in Upland
We service the PGT lines you’re most likely to find on Upland homes: WinGuard aluminum impact-resistant windows and sliding glass doors, WinGuard Vinyl impact windows and doors, the PGT Aluminum Series single-hung and sliding windows, and PGT vinyl double-hung and sliding patio door lines. For parts, we use PGT-compatible OEM or high-quality aftermarket gaskets, rollers, glazing, and hardware matched to your specific series. We stock common components for faster Upland turnaround, and for older units we’ll give you an honest read on whether re-glazing or re-flashing is worth it, or whether the frame has failed and full replacement is the better spend.

FAQs – PGT Construction in Upland
It’s usually both. The fog means the insulated glass seal has failed, and the leak means water is getting past the flashing around the frame. On a 91784 foothill home, the rain that comes off the San Gabriels hits the wall at an angle the original 1960s flashing was never designed for. We fix the glass and the opening together. Call (844) 384-3361 for an exact quote, estimates are free.
Yes, on most PGT sliding patio doors we can replace the rollers and re-seat the track without pulling the whole unit, as long as the frame itself is still square in the opening. If the opening has racked from Upland’s expansive clay, we may need to adjust the framing before the new rollers will track properly. We’ll tell you which situation you have after seeing the door.
They do, especially for north and west elevations that take the brunt of Santa Ana wind. But an older Upland tract home often needs the rough opening reframed and re-flashed before impact units go in, because the original framing was not built to the tolerances that PGT impact units require. We do that reframing as part of the install.
No. Workshop Contractors is an independent our General Contractor in Upland. We are not authorized, sponsored, or warranty-endorsed by PGT. What that means in practice: we work on the basis of our construction experience with PGT products, and we source PGT-compatible parts, not a manufacturer’s stamp. You get an honest assessment, not a sales pitch.
If the pitting is surface-level and the frame is structurally sound, we can refinish and replace the gaskets, which gets you years more service. If the pitting has gone deep into the extrusion, especially near the sill where water sits, replacement is the better spend. We’ll show you the difference on the ladder. Call (844) 384-3361 for an exact quote, estimates are free.

On a 1960s custom ranch in the 91784 foothill pocket, our crew pulled a set of fogged, leaking PGT WinGuard sliding doors whose original flashing had failed after years of wind-driven rain off the mountains. We reframed the rough opening, re-flashed and sealed it, corrected the sill grade so water sheds away from the foundation, and set new PGT units. That’s the kind of fix we deliver in Upland.
