CGI Construction in Los Gatos, CA | San Bruno Construction
We’re San Bruno Construction, and we provide independent CGI service across Los Gatos, from the 95030 flats to the 95033 mountain corridors, with additional CGI service in Monte Sereno available nearby. What sets our CGI work here apart is straightforward: we understand how Santa Cruz Mountains geology and WUI fire codes interact with CGI window, siding, and roofing systems. We’re not a CGI dealer or authorized service center. We’re a full-scope general contractor who has installed, repaired, and replaced CGI products on Los Gatos homes for years, and we know what holds up on a steep, fire-prone slope. Call (866) 472-1908 for a free estimate.
Why Los Gatos Residents Choose Us for CGI Service
CGI makes serious products. Their impact-rated windows and fiberglass roofing underlayment are built for coastal and mountain conditions, and Los Gatos demands exactly that. But a product is only as good as the hands that install it. We’ve worked with CGI sales & service across enough Los Gatos job sites to know where these systems succeed and where they fail when shortcuts get taken.
Noel Carvalho runs our operation. He trained in construction technology at Skyline College and has spent two-plus decades running residential projects across the Bay Area, including hillside work that most flat-lot contractors won’t touch. That background matters when we’re re-flashing a CGI window opening on a 30-degree slope or replacing a CGI ProLine metal roof section where the valley flashing meets Franciscan rock. We don’t guess. We measure, we read the site, and we build it right the first time.

Common CGI Construction Problems We Solve in Los Gatos
CGI products are durable, but Los Gatos conditions are unforgiving. Here’s what we see most often:
- Vinyl window frame warping and seal failure. CGI Select Series vinyl windows can warp and lose seal integrity after years of intense UV exposure and wildfire smoke, especially on exposed hillside elevations. Fogged glass, stiff operation, and air leaks follow. We see this constantly on 95033 ridge homes and even mid-century ranches on the flats.
- StoneGuard siding color fade and chalking. CGI StoneGuard insulated siding holds up well, but west-facing walls bake in afternoon sun. On exposed ridge lines, that means accelerated fading and surface chalking within a decade. The siding still performs structurally, but it looks tired long before its time.
- Metal roof seam separation from storm wind loads. Improperly flashed CGI ProLine standing seam roofs develop seam separation and fastener back-out under atmospheric-river wind loads. Leaks appear near valleys and penetrations, especially on steep-slope homes where water moves fast. Once a seam opens, it needs attention before the next winter storm.
- Fiberglass shingle cracking over CGI 900 Series underlayment. Older Los Gatos ranch homes often get new roofing installed without upgrading attic ventilation. Fiberglass shingles over CGI 900 Series underlayment then crack and blister from trapped heat. The underlayment is fine; the ventilation math was wrong.
- Flashing failures at window and door penetrations. Los Gatos homes built into hillsides shed water unevenly. Where CGI window flanges meet stucco or wood siding on a sloped wall, poor original flashing lets water in slowly, year after year, until the framing tells you something’s wrong.
CGI Service in Los Gatos: What Local Conditions Mean for Your Equipment
Here’s the thing no generic CGI page will tell you: in Los Gatos, any window or siding replacement on a home near the wildland-urban interface must meet ignition-resistant construction standards under California’s WUI fire codes. That requirement doesn’t apply to flat-lot suburban work in Campbell, Cupertino, or areas served by our Lexington Hills CGI service. But drive up Old Santa Cruz Highway into the 95033 corridor, or look at hillside parcels off Kennedy Road and Shannon Road, and the rules change. We’re often specifying CGI’s impact-rated window lines and non-combustible cladding details even when the homeowner only asked for a cosmetic upgrade. That’s not upsell. That’s code compliance on a hillside where wildfire is a real threat, not a theoretical one. It changes what we order, how we flash, and what we document for the Los Gatos building department.
CGI Models & Products We Service in Los Gatos
We service the CGI product lines most common in the Los Gatos housing stock: CGI Select Series vinyl windows, CGI 900 Series fiberglass shingle underlayment, CGI StoneGuard insulated siding, and CGI ProLine standing seam metal roofing. For critical components like window balances and siding panels, we source OEM CGI parts to maintain warranty coverage. For non-structural items, we use quality aftermarket equivalents that meet or exceed CGI specs. We stock common window hardware and fasteners locally so most Los Gatos service calls don’t wait on cross-country shipping. If a CGI window or siding section can be repaired without sacrificing performance, we’ll tell you. We recommend repair first when it makes sense.

Hillside access, WUI-code detailing, and the condition of existing framing all move the number. A mid-century ranch on the 95032 flats is a different job than a custom rebuild on a 95033 slope.

FAQs – CGI Construction in Los Gatos
Yes, when specified with impact-rated glass and proper non-combustible flashings, CGI window lines can meet California’s WUI ignition-resistant construction standards for homes near the wildland boundary in Los Gatos. We confirm the exact spec your parcel requires before ordering. Call (866) 472-1908 if you’ve received a fire-safety compliance notice.
Heavy clay and Franciscan rock create lateral soil pressure against foundation walls and retaining structures, which means we often see settlement-related stress transfer into wall framing and siding. CGI StoneGuard siding performs well, but installation on hillside homes requires stepped flashing and expansion accommodations that flat-lot jobs and our CGI repair in Cambrian Park projects don’t need. We account for that in every 95033 quote.
Yes, we repair CGI ProLine standing seam roofs with seam separation, fastener back-out, or valley flashing damage from winter atmospheric-river storms, and we also handle CGI repair in Saratoga. We recommend addressing leaks before the next storm cycle rather than waiting. Call (866) 472-1908 for a storm-damage assessment.
They are, as long as attic ventilation is upgraded at the same time. Many 1950s and 1960s ranch homes in the 95030 and 95032 flats were built with minimal ridge and soffit venting. New fiberglass shingles over CGI 900 Series underlayment will crack and blister without adequate airflow. We check ventilation first, every time.
For a full impact window installation in Los Gatos, expect $8,000 to $25,000 depending on window count, opening sizes, and WUI-code requirements. A single window replacement starts lower. Call (866) 472-1908 for an exact quote; estimates are free.
