PGT Construction in Saratoga, CA | San Mateo Construction
We’re an independent construction firm that installs and services PGT windows and patio doors across Saratoga’s hillside custom builds and remodels, and we also offer PGT in Monte Sereno. What makes our PGT work different here is simple: we’ve learned to detail every opening for the slope, drainage, and tree-preservation realities that Saratoga throws at a build. If you need PGT service, replacement, or a new installation on a wooded lot in 95070 or 95071, call us at (855) 901-7266 for a free estimate.
Our PGT work spans everything from WinGuard impact-rated windows on fire-exposed hillsides to EnergyVue vinyl replacements on mid-century ranchers. We order direct, we spec to PGT’s published framing and flashing requirements, and we stand behind our installs. We’re not an authorized PGT dealer, and we won’t pretend to be. We’re a licensed general contractor — and our General Contractor in Saratoga team — that knows how these units behave in Saratoga’s specific conditions.
Why Saratoga Residents Choose Us for PGT Service
Noel Carrington, our owner, grew up in San Mateo County and has spent nearly three decades framing, flashing, and finishing custom homes across the Peninsula and the South Bay. He learned the trade the slow way, pouring concrete footings with his father before he ever touched a window jamb. That background matters when a PGT unit is out of square on a 1970s hillside home or a sliding door has been binding for two winters because the original rough opening was never right.
We service every PGT line you’re likely to have in Saratoga: WinGuard aluminum and vinyl, EnergyVue, and the aluminum sliding door series. We keep OEM sash, rollers, hardware, and glazing on order for fast turnaround, and we’re honest when a repair doesn’t pencil out. On a fogged unit, we’ll tell you whether re-glazing saves the frame or whether the whole opening needs replacement. That’s the conversation most homeowners want and rarely get.

Common PGT Construction Problems We Solve in Saratoga
- Sill pan and weep-channel failures on hillside exposures. Winter rain off the Santa Cruz Mountains drives hard against west-facing walls. When sill flashing wasn’t lapped correctly or weep slots are blocked, water tracks into the wall cavity below the opening. We see this on remodels where the original install was rushed.
- Fogged or failed insulating glass on west and south units. Saratoga’s hot, dry summers cook those exposures. Desiccant saturation and seal creep show up as haze between the panes, often years before the frame shows wear. We re-glaze where the frame is sound and replace the unit when it isn’t.
- Roller and track wear on sliding glass doors. Hillside grit and oak litter collect in bottom tracks, then grind the rollers and score the track. Doors bind, misalign, and eventually rack the frame. Replacing rollers and track early is far cheaper than a full door replacement.
- Framing and shim failures in older custom homes. Saratoga has plenty of 1970s through 1990s custom builds with rough openings that were never square. When PGT units were set into those openings during a past remodel, the sashes bind and weather seals gap. We rebuild the opening to spec rather than forcing a new unit into a bad hole.
- Fire-hardening window packages on woodland lots. Saratoga’s wildland-urban interface exposure means more homeowners are upgrading to WinGuard impact units as part of defensible-space work. We detail those openings for both impact and ember resistance.
PGT Service in Saratoga: What Local Conditions Mean for Your Equipment
Here’s the thing nobody tells you about window and door work in Saratoga. Before a permit is even pulled, the town’s tree-preservation ordinance and slope/drainage review can reshape the project. A heritage oak’s root zone sits too close to the proposed opening. A geotechnical report flags fill that won’t hold a foundation line where the architect drew it. The opening moves. The window or door package gets re-scoped. We’ve worked hillside lots off Saratoga-Sunnyvale Road where the original PGT slider was set before the arborist’s oak root-zone report pushed the rear foundation line. The rough opening ended up out of square, and the door bound and leaked for two winters before we were called. Our crew pulled the unit, rebuilt the sill pan with proper backslope and a new weep detail, re-shimmed and flashed a replacement PGT WinGuard unit to the revised opening, and hose-tested the drainage before closing the wall. That’s not a flat-land problem. That’s a Saratoga problem.
For PGT owners, it means ordering windows before the entitlement process settles is a gamble. We help homeowners sequence the order so they’re not paying restocking fees or living with a tarped opening while the tree review plays out.
PGT Models & Products We Service in Saratoga
We work on the full PGT residential range: WinGuard Aluminum impact windows and sliding glass doors, WinGuard Vinyl impact and non-impact lines, EnergyVue single-hung and casement windows, and the PGT Aluminum Series sliders. Our parts approach is straightforward. We use PGT OEM sash, hardware, rollers, and glazing when the unit is serviceable. We specify quality aftermarket glass and screens only when OEM lead times would stall a weather-tight close-up, which happens more often than dealers admit. For Saratoga clients, that means we can usually get a unit weather-tight without waiting on a factory backorder.
San Mateo Construction carries full exterior-to-interior project scope, so PGT window work often sits alongside PGT sales & service for doors, GAF or CertainTeed roofing, James Hardie siding, and kitchen or bath remodels. One contract, one accountable crew.

AfterPGT Service Pricing in Saratoga
Pricing depends on the scope, the unit type, and whether we’re repairing a serviceable frame or replacing the whole opening. Here’s what we quote across Saratoga:
| Service | Price Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Home Addition (with PGT window/door packages) | $45,000 – $130,000 |
What drives cost in Saratoga: hillside access, scaffolding on sloped lots, tree-protection fencing during construction, and the engineering that comes with any opening change on a slope. A flat-lot window swap is a different animal from a hillside WinGuard package that needs fall protection and a re-flashed sill pan. Every free estimate includes a written line-item quote before work starts, so you’ll know the real number. Call (855) 901-7266 to schedule yours.

FAQs – PGT Construction in Saratoga
Yes, often. If the opening is near a protected tree’s root zone or a sloped area that triggers drainage review, the town may require an arborist report or geotechnical input before the permit issues. That can shift an opening or change the foundation plan, which then changes the window or door package you’ve spec’d. We sequence PGT orders after the entitlement process settles so you’re not paying for re-scoped units or restocking fees, and we offer PGT repair in Cupertino as well. Call (855) 901-7266 for an estimate that accounts for the review timeline.
That haze is failed insulating glass, and Saratoga’s hot summer sun on west-facing exposures is the usual culprit. The seal creeps, desiccant saturates, and condensation forms between the panes. The frame can be perfectly fine. We re-glaze PGT units when the sash and frame are serviceable, and we’ll tell you plainly if the whole unit should be replaced instead. Call (855) 901-7266 and we’ll come assess it.
For many hillside lots, yes. WinGuard is designed for impact and windborne debris, and on a wildland-urban-interface lot in the Saratoga hills, that’s a real risk during high-wind fire events. Beyond impact, WinGuard units provide better air and water sealing on exposed slopes than standard windows. We help homeowners weigh the cost against their lot’s specific exposure. Call (855) 901-7266 for a free assessment.
Yes, when the frame is still square and the glass is sound. We replace PGT OEM rollers, tracks, and hardware on sliders that are binding from grit and oak litter in the track. If the frame has racked from being forced, that’s a different story, and we’ll walk you through why a full replacement is the honest call. Call (855) 901-7266 for a quote on a repair versus a replacement.
Window replacements that don’t change the opening size are often simpler to permit, but Saratoga’s design review and hillside constraints can add requirements. If the opening moves or the structure changes, you’re into plan check, geotechnical, and possibly tree review. We pull permits and handle the paperwork on every job we do. Call (855) 901-7266 and we’ll tell you what your specific project will need.
