As an independent contractor, we work directly for you. No dealer markup, no manufacturer authorization implied.

Why Los Altos Hills Residents Choose Us for PGT Service

Los Altos Hills isn’t a flatland subdivision. The town mandates minimum one-acre lots and a 5,000 sq ft maximum footprint, which means homes grow up instead of out. That translates to unusually tall and numerous window and door openings, each one a drainage and structural detail that has to survive hillside wind-driven rain. We’ve installed and serviced PGT windows and doors across the Peninsula’s hillside custom homes for years, and we understand what happens when aluminum frames meet clay-rich slopes and winter storm runoff.

Our team sources OEM PGT rollers, weatherstrip, gaskets, and hardware whenever the frame profile is still supported. On older units where OEM is discontinued, we spec quality aftermarket impact-rated glass. No shortcuts, no callbacks. Nate’s signature phrase on the job site is simple: “Do it once, do it right – everything else is just a future repair bill.” That’s the standard we bring to every PGT service call in Los Altos Hills. We serve the entire Los Altos Hills service area, including 94022.

Common PGT Construction Problems We Solve in Los Altos Hills

Here’s what we see repeatedly on PGT windows and doors in this town, and why these failures happen here more than on flatland lots:

• Slider tracks packed with clay dust and oak litter. Los Altos Hills sits on steep, clay-rich hillsides, and when winter storms hit, runoff carries fine sediment everywhere. Add the town’s native oaks dropping leaves year-round, and your PGT aluminum slider tracks become grinding paste. Panels seize, rollers flatten, and eventually the door won’t move without a fight.
• Wind-driven water intrusion at thin mid-century sealant beads. Many PGT frames installed during the 1960s-80s building boom used thin sealant beads around the perimeter. Los Altos Hills sits in the rain shadow of the Santa Cruz Mountains, but when storms do hit, they hit hard. Wind-driven rain finds those old joints and stains interior drywall at the sill.
• Thermal expansion loosening corner welds and gaskets. Large south-facing aluminum frames on hillside homes get direct sun all day. On PGT doors over 8 feet wide, that expansion and contraction cycle loosens corner welds and gaskets. You’ll see daylight gaps at the corners and latch misalignment that gets worse each summer.
• Bent screen tracks and dented panel faces from arborist staging. The Heritage Tree Ordinance in Los Altos Hills protects native oaks and redwoods, and requires arborist reports for any heritage tree within 50 feet of construction. When arborists stage ladders and material loads near existing windows, those frames take hits that bend screen tracks and dent panels.
• Failed drainage on tall glazing-heavy openings. Because Los Altos Hills homeowners expand vertically rather than outward, many PGT window and door openings are taller than what you’d find in neighboring cities. Tall openings need positive drainage slope and proper sill flashing. When the original install skipped those details, water pools and frames rot from the bottom up.

PGT Service in Los Altos Hills: What Local Conditions Mean for Your Equipment

Los Altos Hills enforces a 5,000 sq ft maximum footprint on one-acre lots. That’s not a zoning trivia fact – it’s the single biggest driver of PGT window and door behavior in this town. Homeowners can’t build outward, so they build upward and glazing-heavy. That means PGT openings here are unusually tall and numerous, and each one functions as both a drainage detail and a structural element that has to survive hillside wind-driven rain.

A standard 36-inch window on a flat San Jose lot deals with occasional rain splash. A 72-inch PGT fixed panel on a south-facing hillside wall off Elena Road deals with wind-driven rain hitting at an angle, runoff from the slope above, and thermal expansion across a large aluminum frame. The original 1970s installs often lacked positive drainage slope, which is why we re-set sill flashing and add slope on nearly every older home we touch in Los Altos Hills. If your PGT frames are still square and draining correctly, re-glazing and re-sealing beats replacement. When the frame is racked, corroded, or the opening has failed drainage, replacement is the honest call.

PGT Models & Products We Service in Los Altos Hills

We service the full range of PGT products found on Los Altos Hills homes, including WinGuard Aluminum Impact Windows and Doors, Series 700 Aluminum Hinged Doors, and PGT Aluminum Series Sliding Glass Doors. Our parts approach is straightforward: OEM PGT rollers, weatherstrip, gaskets, and hardware whenever the frame profile is still in production, and quality aftermarket impact-rated glass only on older units where OEM is discontinued.

For Los Altos Hills turnaround, we stock common PGT hardware locally so we’re not waiting on a distributor in Florida when your slider won’t close before a storm. On a 1970s hillside home off Elena Road, our crew replaced a run of failing aluminum sliders that formed a whole-wall glass view, re-glazing the PGT WinGuard frames that were still square and swapping flattened rollers and cracked gaskets on the rest. We re-set the sill flashing and added a positive drainage slope where the original install had none, and the owners stopped finding water on the interior floor after the first winter storm. That split replacement-and-repair approach kept the mid-century glazing profile intact instead of papering the wall over with stock vinyl.

FAQs – PGT Construction in Los Altos Hills

Can you replace only the failed PGT sliders on my glass wall, or does the whole run have to come out?

Yes, we can replace individual failed sliders without pulling the entire run, as long as the surrounding frames are still square and draining correctly. We did exactly this on a 1970s hillside home off Elena Road, where we re-glazed the PGT WinGuard frames that were still in good shape and only replaced the panels that had racked or corroded. Call (833) 725-3508 and we’ll assess your specific glass wall.

Does the Heritage Tree Ordinance affect how you install or replace PGT windows on a hillside lot?

It can. The Heritage Tree Ordinance in Los Altos Hills protects native oaks and redwoods, and any heritage tree within 50 feet of a construction footprint requires an arborist report. If your PGT window replacement is close to a protected tree, we coordinate with your arborist before staging ladders or materials near the frames. We’ve seen too many bent screen tracks from careless staging to skip that step.

My PGT door frame shows daylight and won’t latch after hot summers – is that a repair or a replacement?

That’s thermal expansion loosening the corner welds and gaskets on a large aluminum frame, which is common on south-facing doors over 8 feet wide in Los Altos Hills. If the frame is still square and the welds are intact, we can replace the gaskets and re-align the latch. If the frame itself has racked or the corner welds have failed, replacement is the honest call. Call (833) 725-3508 for an inspection and exact quote.

Why do my PGT slider tracks keep filling with grit and oak debris?

Los Altos Hills sits on steep, clay-rich hillsides, and winter storms carry fine sediment everywhere. Combine that with native oaks dropping leaves and acorns year-round, and your slider tracks become collection points for abrasive grit that flattens rollers and seizes panels. We recommend annual track cleaning and roller inspection, and we can show you how to do it safely. Call (833) 725-3508 to schedule service.

Can PGT impact windows be installed in a steep-terrain remodel without disrupting my drainage and retaining walls?

Yes, but it requires planning. On steep Los Altos Hills lots, drainage and retaining walls are load-bearing systems, not landscaping accents. We install impact windows with full flashing and positive drainage slope so the window opening doesn’t become a water entry point on the hillside. We also coordinate with your geotechnical engineer when the opening is near a retaining wall.
