PGT Construction in Claremont, CA
We provide independent PGT window and door service across Claremont, from full impact-window replacements to frame repairs and re-glazing on existing units. The thing that makes our PGT work here different is simple: we plan every exterior window change around Claremont’s design review process before the first permit gets pulled. Noel Garrity and our crews at Key Step Construction have rebuilt, re-flashed, and re-glazed PGT units across 91711 for years, and we know which models hold up in the foothill sun and which ones need attention. Call (855) 382-0824 for a free estimate on your PGT project.
Why Claremont Residents Choose Us for PGT Service
We’re not a PGT dealer and we don’t work for the manufacturer. We’re an independent construction firm that has PGT windows and doors on our job sites in Claremont every week, and we also provide PGT service in San Antonio Heights. That distinction matters because we approach PGT work the way a builder does, not the way a sales counter does. Noel Garrity studied construction technology at Santiago Canyon College in Orange and has spent his career working through the kind of remodels and additions that hold up quietly for decades. His approach is direct: diagnose the actual failure, then decide whether a repair makes sense or a replacement is the honest call.
When a Claremont homeowner calls us about a sticking PGT slider or a fogged double-pane, we bring the same full-scope thinking we apply to a whole-home remodel. That means checking the rough opening, the flashing, the weatherstrip, and the frame extrusion, not just swapping a roller and leaving. It also means sourcing OEM PGT parts when they’re available, so the repair matches the original unit instead of forcing a generic component into a system that was engineered to tighter tolerances.

Common PGT Construction Problems We Solve in Claremont
- Sun-baked vinyl frames on west-facing walls. Claremont sits at the base of the San Gabriels, and the Inland Empire UV load is brutal on vinyl extrusions. PGT Vinyl Series units on west-facing walls near the foothills develop warped frames and weatherstrip gaps after five to ten years of exposure. The windows start to whistle during Santa Ana winds and stick when you try to open them. We replace the weatherstrip and realign the sash where the frame is sound. When the extrusion itself is distorted, we’ll tell you plainly that replacement beats repair.
- Loosened hinge screws and worn rollers on aluminum WinGuard units. PGT WinGuard Aluminum Impact Series windows and doors are built to take a hit, but repeated wind loading along the foothill edge works hardware loose over time. We see panels that rack slightly in their tracks, rollers that grind, and hinge screws that back out. We re-torque, shim, and replace worn rollers with OEM PGT parts where the damage is mechanical. If the frame is bent or the panel no longer seats square, that’s a replacement conversation.
- Failed glazing seals on older PGT aluminum windows. Fogging between panes is one of the most common calls we get from the tree-lined streets around the Claremont Colleges. Original factory seals on 1990s and early 2000s aluminum PGT units break down, and once the argon or krypton fill escapes, the insulating value drops and condensation forms. We re-glaze when the sash and frame are in good shape. When the seal failure comes with sill rot or water staining, the whole unit usually needs to go.
- Leaking rough openings from earlier remodels. Impact-rated PGT units installed without proper head flashing during a previous renovation leak when driven rain hits the foothill edge. Claremont gets its share of storm-driven moisture against the mountain front, and a missing or poorly lapped flashing detail shows up as water stains at the top of the window, peeling paint, and drywall damage inside. We pull the trim, re-flash the opening correctly, and reset the unit.
- Design-review conflicts on exterior window changes. This one is specific to Claremont. If you live in the historic core or a Village-adjacent neighborhood, swapping out window styles without running the change through the city’s architectural review can stall your project. We plan PGT replacements around compatibility review from day one, which saves homeowners weeks of back-and-forth and avoids the cost of re-ordering units that don’t match the neighborhood’s character.
PGT Service in Claremont: What Local Conditions Mean for Your Project
Claremont’s preservationist culture changes how PGT window work gets done here. The city’s Village core and the neighborhoods around the Claremont Colleges are full of 1900s to 1930s Craftsman and Period Revival homes, and exterior alterations on those properties often need compatibility review before permits issue. That means a PGT window replacement in Claremont is not a matter of picking a model from a catalog and scheduling installation, unlike a simpler PGT repair in Upland. The style, muntin pattern, frame color, and even the reveal of the window need to work with the home’s original detailing. On a 1920s Craftsman near the colleges, we replaced fogged, leaking PGT aluminum windows that had been installed during an earlier remodel. We matched the original divided-lite look with new PGT WinGuard units, re-flashed the rough openings, and coordinated the exterior trim so the change passed the city’s compatibility review without altering the home’s historic character. That’s the difference between a contractor who knows Claremont and one who just knows windows.
PGT Models & Products We Service in Claremont
We work on all four major PGT product families installed across 91711: the WinGuard Aluminum Impact Series, WinGuard Vinyl Impact Series, the non-impact Aluminum Series, and the non-impact Vinyl Series. For repairs, we source OEM PGT rollers, hinges, weatherstrip, and glazing when the manufacturer still carries the part. When PGT has discontinued a line, we match profile and finish with quality aftermarket components that fit the original extrusion. Impact window installation, full window replacement, and home additions that incorporate PGT products are all in our regular scope.

What drives the cost in Claremont? The size and number of openings, whether the home sits in a design-review district, the condition of the existing rough openings, and the PGT product family you choose. Impact-rated WinGuard units cost more than non-impact Series windows, and additions that trigger structural work push the number up.

FAQs – PGT Construction in Claremont
Yes, in most cases. Homes in Claremont’s historic core and Village-adjacent neighborhoods are subject to architectural review, and exterior window changes of any brand typically need compatibility approval before permits issue. The review looks at style, frame profile, and muntin patterns to make sure the new windows match the home’s original character. We handle this process for our Claremont clients, which is one reason to call us early in the planning stage at (855) 382-0824.
Intense Inland Empire UV on west-facing walls warps PGT Vinyl Series frames over time. The extrusion expands unevenly, which causes sashes to bind and weatherstrip to pull away from the frame, and the gap between the sash and frame is where the whistling comes from during Santa Ana winds. We can realign the sash and replace the weatherstrip when the frame is sound. If the extrusion itself is warped, replacement is the honest fix. Call (855) 382-0824 and we’ll tell you which situation you have after inspecting the units.
Yes, when the damage is limited to hardware. Loosened hinge screws, worn rollers, and misaligned panels are all repairable with OEM PGT parts. What cannot be repaired well is a bent frame extrusion or a panel that no longer seats square, because the structural integrity of the unit is compromised. We’ll always give you the repair-versus-replace call straight, and estimates are free at (855) 382-0824.
Yes, and we specify them on additions regularly. WinGuard impact units handle the Santa Ana exposure along Claremont’s foothill edge well, and their aluminum product line offers the clean sightlines that work with both Craftsman and mid-century additions. Because we’re our General Contractor in Claremont, we can frame the addition, flash the openings, and install the PGT units under one contract instead of handing you off to a separate window crew.
The factory glazing seal breaks down over time, which lets moisture into the space between the panes and allows the insulating gas to escape. We see this most often on PGT aluminum units from the 1990s and early 2000s around the Village and the Claremont Colleges neighborhoods. The fix is either re-glazing the sash or replacing the unit, depending on the frame condition. For an exact diagnosis and a written quote, call (855) 382-0824.
