PGT Construction in Los Altos, CA | Ashford Contractors
We provide independent PGT window and door service across Los Altos, from WinGuard impact systems to standard vinyl and aluminum lines, and also offer PGT service in Los Altos Hills. The difference here is local: we know how PGT units hold up under Los Altos summer heat, wet winters, and one very specific headache nobody mentions until the permit stage. If your PGT windows bind, fog, or leak, call (877) 752-3868 for a free estimate. We’re not manufacturer-affiliated, but we read the spec sheets and order parts by profile and series, not guesswork.
Why Los Altos Residents Choose Us for PGT Service
Most window companies in the Bay Area know PGT as a hurricane brand from Florida. That’s useful, but it doesn’t tell you what happens to a PGT vinyl sash after eight summers on a south-facing wall off Magdalena Avenue. We’ve installed and serviced PGT windows and doors across Los Altos and nearby communities long enough to see the full lifecycle: how the vinyl behaves, where the seals let go first, and when a repair is genuinely smarter than a replacement. That includes Loyola PGT service calls where the same wear patterns show up. Glen Mossier, our owner, trained in construction technology at Skyline College and spent two decades doing structural remodels across San Mateo County. He’s the one who taught our crew to check the rough opening against the actual frame before anything gets ordered twice. That habit matters in Los Altos more than anywhere else we work.
We source OEM PGT replacement sashes, glass units, rollers, locks, and weatherseal whenever the profile is still supported. When OEM is discontinued or the price doesn’t make sense, we tell you and offer a matched aftermarket option instead. You get one contractor, one project manager, and one point of contact whether the job is a single casement swap or a full home addition with impact-glazed openings. That’s how we handle PGT sales & service across the Peninsula, and it’s how we work here too.

Common PGT Construction Problems We Solve in Los Altos
- Binding sashes on south and west elevations. Los Altos summers push daytime heat into the high 80s and 90s for weeks. PGT vinyl frames absorb that heat, expand, and can warp slightly along the profile. We see sashes that stick in August and glide fine in January. Usually the fix is a careful sash reset and new weatherseal, not a new window.
- Fogged or failed WinGuard insulated glass. Wet winters followed by dry summers stress the perimeter seal on older insulated units. When the seal fails, moisture creeps between the panes and the glass fogs permanently. We measure the existing IGU, order the replacement glass, and reglaze on site.
- Slider sill leaks during the rainy season. PGT sliding glass doors have weep systems built into the sill track. When Los Altos oak leaves and winter debris collect in the track, the weep holes silt up and water backs into the house. We clear the track, prove the weeps drain, and replace the sill gasket if it’s gone hard.
- Worn rollers and lazy latches on sliders. Los Altos sits on expansive clay soil that moves with seasonal moisture. That movement transfers into door frames over the years. Rollers drop, strike plates misalign, and latches stop catching. We replace the hardware and realign the door to the shifted opening.
- Failed weatherseal contact on casements. PGT casements rely on a compression seal around the sash. After years of heat cycling, that seal compresses for good and air starts moving through. You’ll feel the draft before you see a problem. New OEM weatherseal restores the original close.
PGT Service in Los Altos: What Local Conditions Mean for Your Equipment
Los Altos is not a typical Bay Area zip code for construction, and the difference is not just lot size. The city’s tree-protection ordinance applies to heritage oaks and redwoods that would be ignored in most of San Mateo County. When a homeowner plans a second-story addition or rebuild, the permit review can require an arborist report and force the entire structure away from a protected root zone. That sounds like a landscaping problem until you realize what it does to fenestration: window and door openings get re-planned mid-permit, and the lumber package changes, which means every pre-ordered window and sliding door has to be re-specified to the revised rough opening.
We’ve handled this before. On a ranch-home second-story addition near the Los Altos Golf & Country Club, we re-specified a set of PGT WinGuard Vinyl casements after the arborist’s report pushed the rear wall line back from a heritage oak root zone. Two of the original units had arrived with sash distortion from a hot delivery week, so we swapped in OEM sashes, reset the frames to the revised openings, and sealed the perimeter before the winter rains. The homeowner got glazing that closes flush and a build that stayed clear of the tree’s protected root zone. That’s the Los Altos difference: the trees shape the glass before the glass ever goes in.
PGT Models & Products We Service in Los Altos
We work on the full PGT lineup, including WinGuard Aluminum series, WinGuard Vinyl series, Aluminum Series sliding glass doors, and Vinyl Series double-hung and casement windows. When a frame is still square and true, we repair and reglaze using OEM parts matched by series and profile. If the frame is distorted or rotting, we tell you straight that replacement is the better spend. We keep common PGT weatherseal, rollers, and hardware accessible for fast Los Altos turnarounds, and we order replacement sashes and glass units directly from the OEM supply chain. No guesswork with part numbers if the label is still legible on the frame.

AfterPGT Service Pricing in Los Altos
Here’s what PGT work typically runs in the Los Altos market, based on our recent projects across 94022, 94023, and 94024, plus PGT service in Stanford.
| Service | Typical Price Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Home Addition | $45,000 – $130,000 |
What drives the cost is the number of units, the series you’re replacing, whether the openings need reframing, and whether the city requires an arborist review that changes the rough openings. A single casement sash replacement costs far less than a full-frame impact window swap. Every estimate from us is free, line-itemed, and based on what we find when we measure the actual opening. Call (877) 752-3868 to schedule yours.

FAQs – PGT Construction in Los Altos
Yes, and we’ve done it more than once. When the arborist report changes your wall lines, the rough openings change, and the originally ordered PGT units often no longer fit. We can re-spec the glass to the revised framing, reorder the correct sizes, and handle the install on schedule. Call (877) 752-3868 if you’re in the middle of a permit review and need to know what your window package will cost to adjust.
Los Altos summer heat cycles the vinyl frames on south- and west-facing elevations, causing slight expansion and distortion. When temperatures drop, the frames contract and the sashes free up. The typical fix is a sash reset and new weatherseal rather than a full replacement. We can tell you which it is after we inspect the unit. Call (877) 752-3868 for a free estimate.
If the frame is sound and the leak is from silted weep holes or a worn sill gasket, repair is almost always the right call. We clear the track, verify the weeps drain, and replace the gasket. If the frame is rotted or the track is too worn, replacement makes more sense. Either way, we’ll give you a straight answer. Call (877) 752-3868 to have it looked at.
We do. WinGuard Aluminum and Vinyl series are both on our list for addition and rebuild work. Impact windows add structural value and typically satisfy the stricter opening requirements that come with mid-permit redesigns. We coordinate the sizing with your framing schedule so the glass arrives to match the revised rough openings. Call (877) 752-3868 to discuss your project.
Window replacement runs $4,500 to $15,000 depending on how many units and which series. Impact window installation starts around $8,000 and can reach $25,000 for larger openings or full-wall glazing. A full home addition with PGT openings falls between $45,000 and $130,000. The best way to know your number is a free on-site measure. Call (877) 752-3868 and we’ll walk the openings with you.
