PGT Construction in Pomona, CA | Elmwood Contractors
We’re Elmwood Contractors, an independent contractor providing PGT in La Verne, Pomona, and surrounding areas with window, door, and construction service. We install and repair PGT WinGuard impact windows, PGT sliders, and PGT vinyl and aluminum lines in homes and apartment buildings throughout the 91766, 91767, 91768, and 91797 ZIP codes. What makes our PGT work different here is simple: we know how these units actually hold up in Pomona’s triple-digit summers, Santa Ana winds, and pre-1978 housing stock. Call (866) 253-8554 for a free estimate on any PGT installation or repair.
Why Pomona Residents Choose Us for PGT Service
Most window contractors in Pomona can sell you a window. Fewer can tell you why a WinGuard laminated unit fogs on a west-facing wall after eight summers, or why an aluminum PGT slider in a 1960s apartment building starts dragging every February. We can. Our crews have installed and serviced PGT lines across Pomona’s bungalow neighborhoods and mid-century apartment stock, plus provided PGT service in Claremont long enough to know which failure modes repeat, which parts hold up, and when a repair is throwing good money after bad.
Nolan Shepherd, our owner, grew up in Fullerton’s Sunny Hills and spent his twenties on ground-up residential work across North Orange County. He’s run Elmwood for two decades, and he specs PGT the same way he specs every other product: the right material in the right place. Everything else is just catching up to that decision. We’re an independent contractor, not a PGT dealer or authorized service center. That matters because we’ll tell you flatly when a PGT unit should be repaired and when it should be replaced. For PGT-specific expertise, see our PGT sales & service overview.

Common PGT Construction Problems We Solve in Pomona
- Fogged WinGuard glazing on east and west exposures. Pomona’s sun is relentless. Glazing seals on PGT WinGuard impact units bake, crack, and fail. Once the IG unit fogs, the impact rating you paid for is gone. We replace the glazing or the sash, not the whole wall.
- Corroded rollers and track pitting on aluminum PGT sliders. Older apartment buildings in Pomona get seasonal water intrusion at slider thresholds. The rollers corrode, the track pits, and the door drags or jumps. We rebuild the track or replace the roller assembly and get the door moving again.
- Warped vinyl frames on sun-facing walls. Triple-digit summer after triple-digit summer, a vinyl PGT frame can bow at the sill. The weather seal breaks, and the next strong winter storm pushes wind-driven rain past the flashing. We replace warped sashes and re-seal the opening properly.
- Delaminated impact laminates on poorly flashed retrofits. Pre-1978 Pomona shells often got window retrofits without proper head flashing. Setting gaskets dry, laminate delaminates, and the unit loses its wind rating. We pull the unit, reframe if needed, and re-flash before setting a correct replacement.
- Undersized rough openings in bungalow retrofits. The pre-1940s bungalows in 91766 and 91767 were framed before modern energy codes. A like-for-like PGT drop-in rarely fits square. We reframe and re-flash the opening so the new unit actually seals and opens.
PGT Service in Pomona: What Local Conditions Mean for Your Equipment
Here’s the thing about Pomona that most PGT pages miss: the same job often pulls together three different eras of construction at once. In the older bungalow blocks of 91766 and 91767, a PGT window retrofit routinely lands in an opening framed before modern energy codes, which means the original rough opening is undersized and out-of-square. We frequently reframe and re-flash rather than drop in a like-for-like unit. That same job trips a code trigger on the electrical side, because the old 100A panel was double-tapped years ago for a window AC unit. So a simple window swap becomes a reframe, a re-flash, and a subpanel upgrade. Contractors who don’t work Pomona quote the window. We quote the window plus what the house is actually going to require when we open the wall. That’s the difference between a bid that holds and one that balloons three days into the job.
PGT Models & Products We Service in Pomona
We install and service the PGT lines most common in Pomona’s housing stock: WinGuard Aluminum impact windows and sliding doors, WinGuard Vinyl impact windows, Aluminum Series single-hungs and sliders you see in mid-century apartment retrofits, and Premium Vinyl double-hungs and casements. We use OEM PGT glazing, sash, roller, and weatherstrip components wherever they’re still available. When the OEM line is discontinued, we spec quality aftermarket hardware matched by profile and rating, so impact or thermal performance isn’t quietly downgraded. That OEM-first approach is why we keep common PGT parts on hand for fast turnaround in Pomona and the surrounding Pomona service area.

AfterPGT Service Pricing in Pomona
Pomona PGT work prices like it does everywhere else: materials, labor, and what the existing opening demands. Here are the ranges we quote for the most common PGT-related jobs:
| Service | Price Range |
|---|---|
| Impact Window Installation | $8,000 – $25,000 |
| Window Replacement | $4,500 – $15,000 |
| Roof Repair (flashing around windows/doors) | $400 – $1,800 |
The final number depends on how many openings, whether the rough openings need reframing, and whether the existing panel can carry the load. A free estimate from us includes a written line-item quote so you can see exactly what you’re paying for. Call (866) 253-8554 and we’ll come look.

FAQs – PGT Construction in Pomona
Usually not. If the frame is square and the opening wasn’t damaged, replacing the insulated glazing unit or the sash restores the unit, and in many cases the impact rating, too. We’ll tell you plainly if the frame is too far gone. Call (866) 253-8554 and we’ll assess it for free.
In most cases, yes. We work from inside where we can, and we’re careful with exterior stucco on pre-1940s bungalows. But if the rough opening is undersized or out-of-square, which is common in 91766 and 91767, we may need to open the wall slightly to reframe and re-flash. Call (866) 253-8554 for an honest site check.
Almost always corroded rollers or pitting on the track from seasonal water intrusion at the threshold. We rebuild or replace the roller assembly, clean and true the track, and get the door moving without forcing it. If you need PGT repair in Montclair or PGT slider service in a Pomona apartment building, call (866) 253-8554.
They can be, with the right glazing and installation detailing. The main risk on Pomona’s west-and-south-facing walls is seal failure from repeated thermal cycling. We recommend glass packages rated for our interior heat load and head flashing sized for our winter storm pattern. Call (866) 253-8554 and we’ll walk you through what applies to your house.
Yes. We handle the full installation envelope including head flashing and sill pans. If the existing roof edge is failing or the flashing is old and compromised, we’ll flag it and often repair it as part of the job. For Los Serranos PGT service or PGT work that includes roof repair, call (866) 253-8554.
