PGT Construction in Claremont, CA | Square One Builders
We’re an independent Claremont contractor that installs, repairs, and retrofits PGT windows and doors across the 91711 zip code, and the quick answer is this: if your PGT windows or patio doors are sticking, fogging, or leaking somewhere in Claremont, we can usually tell you over the phone whether it’s a repair or a replacement. What makes our PGT work different here is that we’ve spent years on Claremont’s older homes, so we know how foothill sun, Santa Ana grit, and heritage-tree shade each wear these units down in their own way. If you’re dealing with a PGT problem, call (877) 688-9930 and we’ll walk you through it.

Why Claremont Residents Choose Us for PGT Service
Most Claremont homes weren’t built yesterday. When we work on a 1920s Craftsman off Indian Hill or a mid-century ranch up toward Padua Hills, we’re usually matching PGT replacement windows to existing openings that haven’t been square for sixty years. That’s the part that separates a clean retrofit from a job that looks patched. We measure, shim, flash, and seal each opening so the new PGT unit sits right, and we keep the original trim profile whenever the house calls for it.
Brent Calloway, our owner, grew up around Midway City and spent three decades on Orange County remodels before Square One Builders expanded into Claremont. He learned framing and finish work through Golden West College’s Construction Technology program, then spent years hauling material and reading blueprints in parking lots until the craft stuck. That background is why we fix what’s worth fixing and say so plainly when a PGT frame has reached the end of its life.
Our service area includes the full Claremont service area, and our crews know the Village, the Claremont Colleges district, and the foothill neighborhoods with the same familiarity.

Common PGT Construction Problems We Solve in Claremont
- Sticky vinyl sashes on the west and south elevations. Claremont’s summers push window surface temperatures high enough that pre-2010 PGT vinyl frames can soften, sag, and distort just enough that the sash binds in the track. We see this constantly on houses with direct afternoon exposure, and the fix is usually re-shimming or replacing the sash, not the whole opening.
- Grit-damaged patio door rollers after Santa Ana events. Wind-driven dust from the wash areas in and around Claremont gets into PGT sliding door tracks, grinds the rollers, and leaves the door heavy. We replace OEM rollers and clean and lubricate the track, and it makes more difference than people expect.
- Fogged insulated glass on partially shaded homes. Claremont’s heritage oaks shade some windows and leave others blasted by sun, so the sealant on dual-pane PGT units fails unevenly. A window that’s shaded all summer can fog years earlier than a hot west-facing unit on the same house, and owners don’t notice it until the view goes milky in the morning.
- Leaking aluminum sills during winter downpours. Older PGT aluminum frames in Claremont often have dried, cracked sealant beads that let water in at the sill during the kind of intense January and February storms the Pomona Valley gets. We re-bed and re-seal the flanges, and if the frame has corroded through at the corners, we replace it.
- Chalked, faded vinyl and cracked corner welds. Foothill UV is hard on vinyl. We regularly see PGT windows from the late 1990s and early 2000s with cracked corner welds and a chalky film that never really cleans up. That’s a structural problem, not a cleaning problem, and it usually points to replacement.
PGT Service in Claremont: What Local Conditions Mean for Your Equipment
Here’s what most window companies won’t mention when they quote a PGT job in Claremont: if you’re replacing windows on a lot with protected Coast Live Oaks, the city may require an arborist report and a tree protection plan before anyone can stage materials or dig. That’s not a formality. Claremont’s tree ordinance is among the strictest in the Pomona Valley, and the mature oaks that shade homes along streets like Bonita, College, and Indian Hill also distort how windows fail from one side of the house to the other. On a 1920s Spanish Colonial off Bonita Avenue near the Claremont Colleges, our crew found PGT vinyl casements on the west elevation with warped sashes that no longer latched and one fogged insulated unit, while the shaded east-side windows were still tight. We replaced the failed units with matching-profile vinyl and re-flashed and sealed the openings, leaving the sound originals in place to keep the historic streetscape intact. That’s the difference between a window swap and a Claremont window job: knowing which units actually need to go.
PGT Models & Products We Service in Claremont
We work on the PGT lines most common in Claremont’s housing stock: PGT WinGuard aluminum impact windows, PGT WinGuard vinyl single-hungs and casements, PGT Aluminum Series sliding glass doors, and PGT Premier Series vinyl windows and patio doors. Where the model is still supported, we use OEM PGT replacement rollers, sash locks, weatherstripping, and glass. When PGT has discontinued a part, we match quality aftermarket hardware so the repair doesn’t turn into a Frankenstein. Fogged dual-pane glass is usually a glass-only swap; a distorted or leaking frame on a 20-plus-year-old unit is often better replaced than patched, and we’ll tell you which side of that line your unit falls on before we quote anything.

AfterPGT Service Pricing in Claremont
| Service | Typical Claremont Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Roof Repair | $400 – $1,800 |
Those ranges reflect what we’ve quoted on Claremont homes over the past several years. Window replacement cost moves with the number of units, whether the openings need reframing, and whether the house sits in a historic review zone that requires matching profiles. Impact window installation runs higher because the laminated glass and heavier frames cost more up front, and they’re a genuine question for Claremont homes near the foothill canyons. Every estimate we give is written, line by line, free, and based on a walkthrough, not a phone call. Call (877) 688-9930 and we’ll set it up.

FAQs – PGT Construction in Claremont
Yes, for many PGT models that are still in production, we source OEM rollers, locks, and weatherstripping without trouble. When a window line has been discontinued, we match aftermarket hardware that fits the original profile closely. The real question is whether the frame itself is still sound, and we’ll tell you that before we order any parts. Call (877) 688-9930 for a straight read on your window.
Usually it’s the track. Claremont’s Santa Ana winds blow fine grit from the wash corridors into door tracks, and that grit chews up rollers and packs into the bearing channels. We clean the track, replace deteriorated rollers, and adjust the door so it glides again. If the panel itself is racked or the frame has shifted, that’s a different repair, and we’ll show you exactly what we’re seeing.
Yes. If you have protected Coast Live Oaks or other heritage trees on your lot, the city may require an arborist report and tree protection plan before we can stage materials or do any excavation. We’ve navigated that process on dozens of Claremont jobs, and we factor the timeline into the schedule so you’re not surprised mid-project.
Impact-rated PGT windows are designed to resist windborne debris and hold their frame and glass under pressure, which is relevant for Claremont homes in the foothill-adjacent canyons. They aren’t a fireproofing product by themselves, but hardened glazing can reduce the risk of ember entry through a blown-out window. We can walk you through what impact ratings actually mean for your elevation and exposure. Call (877) 688-9930 and we’ll help you price it.
Fogged dual-pane glass is generally worth a glass-only swap if the frame and sash are still square and the hardware works. If the frame is distorted, the corner welds are cracked, or the unit is leaking at the sill, replacement is usually cheaper over five years than repeated patching. We’ll inspect it and give you both numbers before you decide.
