PGT Construction in Los Altos, CA | San Mateo Construction
We provide independent PGT window and door service across Los Altos, from fogged WinGuard glass replacements on University Avenue to full impact-window installations on hillside rebuilds. What makes our PGT work different here is simple: we know how Los Altos planning review treats window and door changes, and we prepare submittals that get through without months of back-and-forth. San Mateo Construction is not authorized by PGT, but we’ve installed and repaired their products in Los Altos long enough to know exactly what works in this town’s ranch homes and new-build lots. Call (855) 901-7266 for a free estimate on any PGT repair or replacement.
Why Los Altos Residents Choose Us for PGT Service
PGT makes a lot of different window lines, and not every contractor knows the difference between a WinGuard vinyl sash and an older aluminum series frame. We do. Noel Carrington, our owner, grew up in San Mateo County and has spent three decades working residential and light commercial jobs here. He’s walked enough Los Altos job sites to tell you, straight, whether a fogged dual-pane unit is worth rebuilding or if you should replace the whole opening. We keep OEM PGT parts in regular rotation: sashes, balances, weatherstripping, and insulated glass units. When a PGT part is discontinued, we source aftermarket components that match the original fit, and we’ll tell you which route we’re taking before we order anything. You get one accountable team from the first measurement to the final inspection sign-off.
Los Altos homeowners tend to research before they commit. That works well with how we operate. We’re a full-service Los Altos General Contractor, not a window-only shop, which matters when a window replacement turns into a stucco repair or a header adjustment. The same crew that re-glazes a PGT slider can also replace the surrounding trim, patch the stucco, and coordinate with the arborist if the oak canopy starts getting involved. You’re not juggling three vendors over one window opening.

Common PGT Construction Problems We Solve in Los Altos
Here’s what we see most often in Los Altos PGT units, and why it happens in this specific climate and housing stock:
- Fogging and seal failure in dual-pane WinGuard units on south- and west-facing windows. Los Altos gets strong afternoon sun with little marine layer to soften it. Thermal cycling stresses the insulated glass seals, and after a decade or so, the fog shows up. We replace the glass unit rather than the whole frame when the sash and balance are still in good shape.
- Water intrusion at sill and frame corners on original PGT aluminum windows in 1950s and 1960s ranch homes. These houses were built before modern flashing standards existed. Winter rain finds the stucco cracks around the frame, and the sill pans were never designed to route water out. We fix the flashing, repair the stucco, and reset the window so it drains properly.
- Sticking or difficult-to-operate PGT sliding glass doors. Dusty, dry summers in the Santa Clara Valley put grit into vinyl tracks. Add worn rollers and the door starts sticking, or worse, jumps the track. We rebuild the track assembly and replace rollers with OEM-compatible parts.
- Premature finish peeling or fading on PGT vinyl and wood-clad windows. Prolonged sun exposure on the unshaded sides of Los Altos lots accelerates UV degradation. When the finish has failed, we’ll assess whether a refinish makes sense or if replacement is the better spend.
- Home additions that require matching new PGT units to existing openings. Los Altos sees a lot of second-story additions and ADU builds. Matching new PGT windows to what’s already on the house requires knowing the original product line and how it ages. We spec the right model and glass package so the addition doesn’t look like an afterthought.
PGT Service in Los Altos: What Local Conditions Mean for Your Equipment
Los Altos is a low-density Silicon Valley town of mostly 1950s and 60s ranch homes on generous lots, and the Los Altos Home Remodeling trade here is overwhelmingly tear-down-and-rebuild, major additions, and ADUs rather than repair. Every project runs through a notoriously resident-driven, design-review-heavy city permitting culture. What does that mean for PGT owners? If you’re replacing windows in a visible front elevation, Los Altos planning typically requires architectural review and neighbor notification before you can pull the permit. That’s not a suggestion, and it’s not something you can skip. We prepare detailed product specs and elevation drawings upfront, so the submittal goes in clean and comes back approved without months of delay. A contractor who doesn’t know this can cost you a full season. In nearby towns you might swap a window in a week. In Los Altos, the paperwork runs the schedule, and we plan around it from day one.
There’s another local factor worth knowing. Lots on the hillside and PGT service in Los Altos Hills-adjacent edges back onto mature oak and redwood canopies. Tree-protection and arborist review routinely reshape foundation and excavation plans before a shovel hits the ground. For window and door work, this matters when the project scope grows: a home addition that needs new PGT windows on a treed lot may trigger tree-protection conditions that change where and how you build. We coordinate the arborist review alongside the building permit so the window order doesn’t sit in a warehouse while the tree report gets sorted out.
PGT Models & Products We Service in Los Altos
We work on the PGT lines most common in this market: WinGuard Vinyl, the PGT Aluminum Series, PGT SolarZone, and PGT Custom Vinyl. WinGuard shows up most often on newer builds and additions where impact rating matters. The Aluminum Series is what you’ll find on original ranch homes from the 50s and 60s. SolarZone is the low-E line that Los Altos homeowners choose for sun-exposed elevations, and Custom Vinyl covers odd-sized openings on remodels. We service the full range: fixed windows, single-hung, casement, sliding glass doors, and impact-rated units. For parts, we source OEM PGT components whenever the line is still in production. When a part is obsolete, we use high-quality aftermarket alternatives that match the original dimensions and finish. We’ll always tell you which parts path we’re taking and why.

FAQs – PGT Construction in Los Altos
Yes, in most cases. Los Altos requires building permits for window replacement whenever the opening size changes, structural headers are altered, or the windows are in a visible front elevation subject to architectural review. Like-for-like swaps in rear elevations sometimes proceed under a simpler review, but we’ll confirm with the city before we order anything.
Original 1950s and 60s ranch houses in Los Altos usually have single-hung or fixed PGT Aluminum Series units with wide sightlines and thin frames. Remodels and additions typically move toward WinGuard Vinyl or SolarZone casement and picture windows for better thermal performance and cleaner sightlines. We match the new units to the original openings where possible, or we reframe the opening if you want a different configuration.
Often, yes. If the sash, frame, and hardware are still sound, we can replace just the insulated glass unit and reseal the sash. That runs a lot less than a full window replacement. When the frame is warped, the balance is failing, or the seal failure keeps recurring, we’ll be straight with you: replacement is the smarter spend. Call (855) 901-7266 and we’ll assess your specific windows.
If new window openings or a home addition requires excavation near a protected oak or redwood, the city may require an arborist report and tree-protection plan before the permit is issued. That can affect footing placement, driveway work, and how we stage materials. We coordinate the arborist review alongside the building permit so the window order and the site work stay on the same timeline.
Standard PGT WinGuard and SolarZone orders typically run four to eight weeks from order to delivery, depending on glass package and size. Custom dims or impact-rated configurations can push past ten weeks. We confirm the lead time before we finalize the permit submittal, so the window arrives when the site is actually ready for it.
