PGT Construction in Montclair, CA | Workshop Contractors
We provide independent PGT window and door service across Montclair, and the work here almost always comes down to one thing: retrofit installation into 1950s-70s tract openings that stopped being square decades ago. We’re Workshop Contractors, led by Noel Figueroa, and we’ve spent years setting PGT vinyl units into Montclair’s postwar stucco-and-wood-frame homes. We handle window replacement, impact window installation, and full home additions. Call (844) 384-3361 for a free estimate on any PGT job in the 91763.
Why Montclair Residents Choose Us for PGT Service
Montclair’s housing stock is mostly single-story tract homes from the 1950s through 1970s. The rough openings in those walls were framed when dimensional lumber was actually dimensional, and nothing has stayed square through six decades of Pomona Valley heat and Santa Ana wind. We know how PGT vinyl windows and sliding doors behave when they meet those openings because we’ve reframed and flashed more of them than we can count.
Noel grew up in the Vineyard neighborhood of Ontario, where he provided PGT service, and learned framing from the generation of tradesmen who built these same tract houses. He studied construction technology at Chaffey College and has worked across the Inland Empire ever since. That background matters when a PGT window needs to sit true in a wall that hasn’t been true since before most Montclair homeowners were born.
We use genuine PGT replacement sashes, glazing, rollers, and weatherstripping when the unit is structurally sound. If the frame itself is compromised, we tell you honestly and price full-frame replacement instead. No games, no padding the job.

Common PGT Construction Problems We Solve in Montclair
These are the failure modes we see most often on PGT units in Montclair’s 91763 tract homes:
- Cracked and separated vinyl sash corners. The Pomona Valley swings from 100-plus degree summers to cold winter nights, and Santa Ana wind events push against south- and west-facing windows. Years of that thermal cycling makes PGT vinyl corners crack and separate, especially on elevations that catch the afternoon sun.
- Fogged dual-pane insulated glass. Seal failure shows up as hazy glass before any frame issue appears. We see this most often on PGT installs from the 1990s and 2000s, where the desiccant in the spacer has long since given out.
- Corroded sliding door rollers and bound tracks. Montclair’s flat, small lots don’t drain fast when winter rain comes through, and water works past worn weatherstripping on builder-era PGT sliding doors. Then the tracks corrode and the rollers bind, and the door fights you every time you open it.
- Racked frames in out-of-square rough openings. When a PGT frame sits in a stucco wall that’s shifted over 60 years, the sashes stick and the locks misalign. The window isn’t the problem. The opening is.
- Gateway wear on high-use patio doors. Montclair families live through their back doors year-round. PGT patio sliders on converted-garage and rear-facing elevations wear through rollers and weatherstripping faster than the rest of the house.
PGT Service in Montclair: What Local Conditions Mean for Your Equipment
Montclair is built out. There is no greenfield left, and nearly every PGT window or door job here is a retrofit into an existing 91763 tract-wall opening, not new construction. That changes everything about how the work gets scoped. On the small postwar lots near the 91763 core, the original detached garage often sits within inches of the rear property line. If you’re adding windows or a door to an ADU conversion or room addition, the very first question is whether the footprint clears the setback requirements. That’s a survey question before it’s a window question, and we don’t order a single PGT unit until the property line is confirmed.
We’ve seen it on a 1950s single-story stucco tract house in the 91763 core: the original PGT sliding door frame was racked against an out-of-square rough opening, two dual-pane units had failed seals, and the rollers were corroded. We reframed and flashed the opening, set new PGT WinGuard vinyl units, and replaced the door rollers and weatherstripping. And because the detached garage sat inches off the rear property line, we had the setback confirmed before finalizing the door locations. That’s the difference between working in Upland with PGT service or Montclair and working somewhere with new subdivisions to absorb the mistakes.
PGT Models & Products We Service in Montclair
We work on PGT WinGuard impact-resistant vinyl windows and sliding glass doors, PGT PremiO and Premium vinyl single-hung and casement windows, PGT aluminum and vinyl patio sliding doors, and PGT vinyl double-hung retrofit units for existing openings. Our approach on parts is straightforward: use genuine PGT replacement sashes, glazing, rollers, and weatherstripping where the unit is structurally sound, and use quality aftermarket hardware when a factory part no longer makes sense. We keep the common parts stocked for fast Montclair turnaround on standard retrofits. For impact-rated glass, we order PGT WinGuard units to spec, and we’ll give you the lead time before we start tearing anything out.
We’re an independent contractor, which matters to how we work. We’re not authorized, sponsored, or backed by PGT. We buy and install their product because we’ve tested enough vinyl windows over the years to know which ones hold up in this climate. If a PGT unit is the right call for your Montclair home, we’ll recommend it. If another product fits the job better, we’ll tell you that too.

AfterPGT Service Pricing in Montclair
Here’s what PGT window and door work typically runs in the Montclair area, based on what we’ve scoped across the 91763:
| Service | Typical Price Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Home Addition (with windows and doors) | $45,000 – $130,000 |
What drives the cost on PGT work in Montclair is the opening, not the product. An out-of-square rough opening means reframing and flashing before the new unit goes in, and that adds labor hours. On an impact window job, the glass itself is heavier and the installation requirements are stricter than a non-impact unit. A free estimate from us includes an on-site look at the existing openings, the property line situation if it applies, and a written line-item quote so you know exactly where the money goes. Call (844) 384-3361 to schedule yours.

FAQs – PGT Construction in Montclair
No. We are an independent general contractor. We buy and install PGT products on our own judgment because they perform well in Montclair’s climate, but we have no manufacturer authorization and we don’t claim any. That independence means we recommend the right product for the job, whether it’s a PGT unit or a different brand entirely. For the full range of what we offer, see our PGT sales & service page. Call (844) 384-3361 for an honest assessment of your windows and doors.
Yes, in most cases. Impact window installation in Montclair’s 1950s-70s tract homes comes down to whether the existing rough openings are square enough to take the weight of impact-rated glass. We reframe and flash openings as needed, then set the PGT WinGuard units. The job is heavier and the tolerances are tighter than standard window replacement, which is why the price range runs $8,000 – $25,000 depending on how many openings and whether reframing is required. Call (844) 384-3361 for an exact quote, free.
Most of the time, the repair is the right call. If the rollers are corroded or the tracks are bound, we can replace the rollers, clean and re-grease the tracks, and replace the weatherstripping for a fraction of what a new door costs. But if the frame itself is racked from an out-of-square opening, or if the glass is fogged, replacement starts to make more sense. We’ll tell you straight which one we’d do if it were our house. Call (844) 384-3361 and we’ll come look at it.
It can, yes. Montclair is fully built out, and on the small postwar lots near the 91763 core, original detached garages often sit within inches of the rear property line. Any addition that extends the living footprint, including windows and doors that open into new space, gets reviewed against setback requirements. We confirm the property line and the setback before ordering a single PGT unit. It adds a step, but it keeps the project from getting flagged mid-build. Call (844) 384-3361 to discuss your ADU scope.
Fogging is a dual-pane seal failure. The insulated glass unit loses its seal, moisture gets inside, and the glass hazes over. Corner cracking on the vinyl sash is thermal cycling: decades of Pomona Valley summer heat followed by cold snaps and Santa Ana wind stress, especially on south- and west-facing elevations. Both are repairable if caught early. We replace failed insulated glass units and cracked sashes with genuine PGT parts where the frame is still sound. Call (844) 384-3361 to schedule an inspection.
