CGI Construction in Boulder Creek, CA | Seaside Contractors
CGI window, door, and siding service in Boulder Creek comes down to one reality: these products perform differently in canyon conditions than they do anywhere else. We’re an independent contractor, not a CGI dealer, which means we can tell you straight whether a CGI product is the right call for your home or whether another line makes more sense. Led by Glen Sorrento, our crew has spent years installing and retrofitting CGI windows, doors, and siding on Boulder Creek’s steep, shaded lots. We know where these products fail and how to keep them working. Call (833) 589-8103 for a free estimate.
If you’re researching CGI for a Boulder Creek home, you’re probably weighing impact ratings, thermal performance, and how a product handles redwood shade and winter rain. That’s the right conversation to have. You can learn more about our broader CGI sales & service work, but this page covers the local specifics that matter here.
Why Boulder Creek Residents Choose Us for CGI Service
Boulder Creek homes are not like suburban tract houses. You’ve got older redwood cabins, 1960s and 70s mountain builds, and scattered post-fire rebuilds sitting on pier-and-post foundations. A window or door replacement here often means working around non-conforming footprints, single-wall redwood interiors, and county rules that don’t apply down the hill. We know what those jobs look like before we show up.
Glen Sorrento grew up in Foster City’s Shell Cove neighborhood, watching lagoon-side homes get built and rebuilt for years. He studied building construction technology at College of San Mateo, then spent more than two decades working through just about every project type the region offers, including CGI service in Ben Lomond and surrounding mountain communities. That background matters when a CGI product needs to be evaluated honestly. We’re familiar with the Sentry, Elite, Pro, and Woodlands lines, and we’ll tell you when a repair makes sense versus when you’re better off replacing the unit outright.
We’re independent, which means no brand bias. If a CGI product is right for your home, we’ll spec it correctly. If another window or door line fits the conditions better, we’ll say so.

Common CGI Construction Problems We Solve in Boulder Creek
- Sticking and warped vinyl window frames. CGI Elite Series vinyl windows can warp and bind in Boulder Creek’s summer heat and winter freeze cycles, particularly on south-facing walls with no tree cover. A window that won’t close properly stops being an annoyance and becomes a security and weatherproofing problem.
- Corroded sliding glass door rollers. Under heavy redwood canopy, CGI sliding door tracks collect needles, mud, and moisture. Rollers corrode, and the track alignment shifts. We see this constantly on older homes along Highway 236 and the side roads off it.
- Hairline cracks in fiberglass entry doors. CGI Sentry Series doors can develop fine cracks at the hinge and lock stiles after years of swelling and shrinking from fog drip and winter rain. These cracks start small but let moisture into the door core.
- Failed patio door seals and weatherstripping. Constant redwood shade and moisture degrade seals faster here than in sunnier towns. Drafts, water intrusion, and higher heating bills are the usual symptoms.
- Warped frames from deferred repairs. A minor issue left unaddressed through one wet winter becomes a bigger problem. We’ve replaced units that likely could have been repaired if they’d been caught early.
CGI Service in Boulder Creek: What Local Conditions Mean for Your Equipment
Here’s the Boulder Creek-specific reality that doesn’t get discussed on generic CGI pages: on our narrow canyon roads, fire-safe roof assemblies and defensible-space clearances are enforced more strictly than in nearby towns like Watsonville or Freedom. When a CGI window or door replacement alters wall penetrations, the county often triggers a roof inspection and upgrade requirement as part of the permit. That means a simple window swap can become a roofing conversation. We’ve managed enough of these projects to plan for it from the start. If your home needs a roof upgrade before or alongside your CGI work, we handle that too through our Boulder Creek service area coverage. Let’s figure out what the job actually needs, then we’ll talk materials.
We also replaced a failing CGI Elite Series sliding glass door in a 1970s redwood cabin off Highway 236 near CGI service in Lompico where the rollers had seized and the track was packed with redwood needles and mud. After clearing the track and installing new OEM rollers, we found the door frame had warped beyond adjustment. We upgraded to a CGI Pro Series unit with a corrosion-resistant track and added a small overhang to keep debris out. That homeowner now has a door that glides correctly and seals tight against winter drafts.
CGI Models & Products We Service in Boulder Creek
We work on CGI Elite Series vinyl windows, CGI Pro Series sliding glass doors, CGI Sentry Series fiberglass entry doors, and CGI Woodlands Series patio doors, including Felton CGI service calls for all four product lines. For parts, we source OEM CGI components like rollers, seals, hinges, and glass units whenever available. When a part is obsolete or backordered for too long, we use high-quality aftermarket equivalents that match the original specs. We don’t stock every CGI part locally, but for the most common failure points on Boulder Creek homes, we can usually get what’s needed within a few days.
When a CGI window or door has reached the end of its service life due to repeated failures, rot, or frame warping, we give you a straight recommendation on repair versus replacement. No brand loyalty. Just what makes sense for your house.

FAQs – CGI Construction in Boulder Creek
Yes. Boulder Creek is in unincorporated Santa Cruz County, so window and door replacements that alter wall openings require a county permit. If the job changes wall penetrations, expect a roof and defensible-space review as part of the process. We handle the permit paperwork and sequencing for you. Call (833) 589-8103 and we’ll walk you through what your specific property will require.
The vinyl frames are expanding and contracting with Boulder Creek’s temperature swings, and the weatherstripping has likely degraded from moisture exposure. South-facing walls with direct sun get the worst of the summer sticking. Winter leaks usually come from failed seals that let water through during heavy rain. We can replace the weatherstripping and re-align the sash, or tell you if the frame has warped past repair.
Usually, yes. We replace the rollers with OEM CGI parts when available, clear the track of redwood needles and mud, and re-align the door. If the frame has warped from moisture, which happens often under Boulder Creek’s tree cover, repair might not be worth the cost. We’ll tell you which situation you’re in before we do any work.
When a window or door replacement changes wall penetrations, the county often inspects the roof assembly and defensible-space clearance as part of the permit. If your roof is not fire-safe compliant, you may need to upgrade it before or alongside the window work. We plan for that from the first site visit so you’re not surprised mid-project.
CGI Sentry Series fiberglass doors hold up reasonably well in Boulder Creek, but they can develop hairline cracks at the hinge and lock stiles from years of fog drip and winter rain swelling and shrinking the material. If you catch the cracks early, they’re repairable. If they’ve been open for years, the door core may have absorbed moisture. We’ll inspect yours and give you a straight answer on repair versus replacement. Estimates are free. Call (833) 589-8103 to book one.
