PGT Construction in Los Altos, CA | San Bernardino Contractors
We provide Loyola PGT service and independent PGT window and door service across Los Altos, and the one thing that makes our work here different is simple: we know this town’s design review process inside out. Replacing a street-facing PGT window in Los Altos isn’t just a swap-it-out job. It can trigger a discretionary review where neighbors weigh in on grille patterns, frame colors, and sight lines. So we plan for that before we order a single unit.
Ruben Castillo and our crew at San Bernardino Contractors have been handling PGT installs and repairs long enough to know the difference between a seal failure and a framing issue. We’re one contractor, every phase, from the roof down to the pavers. If you’re in 94022, 94023, or 94024 and your PGT windows are fogging, sticking, or leaking, call (855) 473-5620 for a free estimate.
Why Los Altos Residents Choose Us for PGT Service
PGT builds windows that handle hurricane-force wind loads, but here in Los Altos, the real test is time. Hot, dry summers bake west-facing units in 1950s ranch homes until the seals let go. Wet winters push water against sills that haven’t been re-flashed since Eisenhower was in office. We see these failure patterns every month across 94022 and 94024.
Ruben grew up watching his uncle reroof houses and frame garages on a shoestring budget in San Bernardino’s Westside, and that education never left him. He completed his construction technology training at San Bernardino Valley College, where he got serious about load paths, flashing details, and not cutting corners on anything structural. When we evaluate your PGT windows, we’re looking at the whole wall assembly, not just the glass.
We source OEM parts for PGT windows whenever they’re available. When a window is obsolete, we use quality aftermarket components that fit correctly and last. You pick the brand, we handle the build. And we handle the permits, the paper, and the design review packet too.

Common PGT Construction Problems We Solve in Los Altos
- Seal failures in dual-pane PGT units. Fogged glass between the panes means the argon or krypton fill is gone and the insulating value is shot. Los Altos summers run hot and dry, and repeated thermal cycling is what kills these seals. We replace the insulated glass unit, not the entire window, whenever the frame is still sound.
- Frame and sash warping in older PGT vinyl windows. Vinyl expands and contracts with temperature swings. South-facing windows in 94022 take the worst of it. The sash starts binding, the locks stop lining up, and the window gets harder to operate every year. Sometimes the fix is new hardware and a track adjustment. Other times the frame itself has moved enough that replacement is the honest call.
- Water intrusion at corners and joints. Los Altos sits on expansive clay soils. When winter rains arrive, that clay swells and foundations shift. A window that was square a decade ago is now racked a quarter inch. Water finds the gap at the sill corner and the leak shows up on the interior drywall. We re-level the unit, re-flash the opening, and replace the weatherstripping and sealant with modern materials.
- Hardware failures in PGT casement and slider windows. Cranks strip, rollers flatten, locks stop engaging. It’s worse in homes going through remodels, because the windows get opened and closed constantly while tile dust and drywall grit work into every moving part. We stock replacement cranks, rollers, and lock sets for PGT Defender Series and WinGuard lines so we can fix these without waiting on a parts order.
- Design review issues with street-facing replacements. This one’s Los Altos-specific. A homeowner orders a new PGT window with a different grille pattern than the original, and the city wants to see a submittal before sign-off. We prepare the product spec sheet and photos so the neighbor who reviews your application can see exactly what’s going in.
PGT Service in Los Altos: What Local Conditions Mean for Your Equipment
Here’s what most Los Altos General Contractor competitors miss about this city: this city runs a strict one-house-per-lot culture enforced through meticulous design review. Construction here is less about building big and more about invisible craftsmanship. Matching existing ranch-house character, preserving sight lines, not changing what the street looks like. That’s the game. If your PGT replacement windows are visible from the street, a neighbor can object. The Planning Commission can stall the project for months over a grille pattern.
So we do something most window installers won’t. We prepare a detailed submittal with product specs, elevation photos, and color samples before we order anything. It costs a little time up front and saves the project from sitting idle through two commission cycles. Ruben’s line on this: if it’s not built right the first time, you’re just paying for it twice. That applies to the paperwork as much as the flashing.
PGT Models & Products We Service in Los Altos
We work on the full PGT residential line. That includes PGT WinGuard Aluminum, the heavy-duty impact-rated frame system you’ll see on newer additions and ADUs. PGT WinGuard Vinyl shows up in a lot of remodels where homeowners want impact protection without the aluminum look. PGT Solarban 60 glass is a popular upgrade for west-facing windows in Los Altos, where afternoon sun cooks the living room. And the PGT Defender Series remains a budget-conscious choice for garage conversions and unheated spaces.
We’re not a PGT factory outlet. We’re an independent service provider, which means we can repair with OEM parts or honest aftermarket equivalents depending on what’s still in production. We keep fast-moving parts stocked for Los Altos jobs: rollers, cranks, lock sets, weatherstripping, and common insulated glass unit sizes.

AfterPGT Service Pricing in Los Altos
| Service | Price Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Roof Replacement | $8,000 – $20,000 |
Window replacement pricing in Los Altos swings on three things: how many units, whether they need impact-rated glass, and whether street-facing elevations trigger design review. A single fogged window might run under a thousand and take an afternoon. A whole-house PGT WinGuard package on a 2,400-square-foot ranch can push past twenty grand once you factor in tempered glass, Low-E coatings, and trim matching the original 1962 detailing.
Every free estimate includes a line-by-line scope with the window sizes, styles, and glass specs written out. No voodoo. Call (855) 473-5620 and we’ll schedule a walkthrough.

FAQs – PGT Construction in Los Altos
Yes, in most cases. Los Altos requires permits for window replacement when the opening changes size, when structural headers are touched, or when the windows are visible from the street and subject to design review. Like-for-like replacements in the same openings sometimes fly under a simpler path, but we always check with the city before ordering glass. Call (855) 473-5620 and we’ll tell you what your specific address triggers.
The clay under Los Altos swells in winter and shrinks in summer. Over decades, foundations shift and window openings go slightly out of square. A new PGT window won’t fix a racked rough opening, so we check each opening with a level and square before we order. If the framing has moved beyond shim range, we address it during the rough-in stage rather than forcing the window and hoping the trim hides the gap.
You can replace the insulated glass unit without replacing the frame. If the PGT frame and sash are in good shape, we order a new IG unit with matching Low-E and tint, swap it into the existing sash, and re-seal. That runs far less than a full window. If the frame is warped, the corners are leaking, or the hardware’s failing too, replacement becomes the cheaper long-term option. We’ll tell you which way to go and show you the numbers either way.
The 1940s to 1960s ranch inventory in Los Altos was built with horizontal sight lines and wide, low windows. PGT picture windows with narrow frames, casements on the ends, and matching single-hung or slider units preserve that look. We typically recommend WinGuard Vinyl for ranch remodels because the frame profiles blend better than aluminum with original wood trim. Call (855) 473-5620 for a design review walkthrough and we’ll show you what fits your elevation.
The October through April rain window is real here, and wet-installing a window in Los Altos clay means managing water at the rough opening before the new unit goes in. We schedule tear-outs for dry days or stage plastic and drainage so the interior never gets soaked. If your project runs long, we re-flash the opening with modern tape and pan flashing so a January rain doesn’t find its way behind the siding. We’ve replaced enough leaky windows in 94022 to know exactly where water sneaks in.
