CWS Construction in Boulder Creek, CA | San Bernardino Contractors
We provide independent CWS window, door, and cabinetry installation and repair across Boulder Creek, with pricing that reflects this mountain market: window replacement runs $4,500 – $15,000, impact windows $8,000 – $25,000, and home additions $45,000 – $130,000. What makes our CWS work different here is simple: we’ve rebuilt homes on CZU-scorched parcels and know how CWS products actually perform against Chapter 7A fire codes and canyon weather, not just showroom conditions. Call (855) 473-5620 for a free estimate, and we’ll walk you through what your specific lot in Boulder Creek actually needs.
We carry CWS sales & service expertise from the San Bernardino market into the Santa Cruz Mountains, where the rules are different and the stakes are higher. Boulder Creek service area work means steep driveways, narrow access roads, and wildfire-recovery permitting that flatland contractors never deal with.
Why Boulder Creek Residents Choose Us for CWS Service
Ruben Castillo, our owner, got his start framing and reroofing houses in San Bernardino’s Westside, then spent better than two decades working the Inland Empire before CZU recovery pulled our crews into the Santa Cruz Mountains. That background matters when we’re standing on a Boulder Creek hillside lot, looking at a CWS sliding door that’s been grinding on redwood duff and ash grit since the 2020 fire. We don’t just replace the roller; we look at how the deck settled after the fire, how the drainage shifted, and whether the rough opening itself is still square.
OEM CWS parts come first on every job, when they’re still available. When they’re not, we tell you plainly and quote a fire-rated replacement instead of patching a 30-year-old vinyl unit that’s never going to pass a rebuild inspection. One contractor, every phase, from the roof down to the pavers.

Common CWS Construction Problems We Solve in Boulder Creek
- Warped vinyl frames on south-facing canyon walls. Sun exposure in Boulder Creek is brutal on the uphill side, especially on lots off Bear Creek Road and Highway 9. Years of UV and summer heat cycling warp CWS 4000 Series vinyl double-hung frames until the sash no longer seals. Winter rain finds those gaps fast. We re-flash the rough opening and set new tempered glazing when needed.
- CWS sliding glass door tracks packed with redwood duff. Decks rebuilt after CZU sit under redwoods and madrones that dump debris constantly. The tracks on CWS sliding patio doors fill with that duff, the rollers chew through it, and the door starts binding or won’t latch. We clean, rebuild, or replace the roller assembly and adjust the track so the door actually locks for defensible-space compliance.
- Fogged insulated glass on west-facing hillside homes. West-facing CWS units in Boulder Creek take full afternoon sun, then cold mountain nights. That cycle breaks the seal on insulated glass units. Fogged glass fails energy compliance on rebuild sign-offs. We replace the IGU with OEM CWS glass where available, or spec a Chapter 7A-rated unit if the whole window needs to go.
- Degraded weatherstripping and flashing on older CWS openings. On scorched lots next to surviving homes, the seals on windows and doors were never fire-rated for Chapter 7A. Smoke intrusion shows up at those weak points during prescribed burns or the next wildfire. We replace weatherstripping, re-flash rough openings, and bring the assembly up to current WUI standards.
- CWS fiberglass and steel entry doors that don’t seal after hillside settling. Boulder Creek slopes move. A door that swung clean in 2019 binds by 2025 because the hillside settled half an inch. We re-hang the door, adjust the threshold, and verify the fire-rated gaskets still seal.
CWS Service in Boulder Creek: What Local Conditions Mean for Your Equipment
Boulder Creek lots are a patchwork of CZU-scorched parcels beside surviving homes. That means any addition or rebuild here has to meet Chapter 7A fire-resistant assembly rules on exterior glazing and doors, even when the neighbor’s house still has original single-pane windows from the 1970s. We see this mismatch constantly: a homeowner wants to match the look of an old redwood cabin, but the county requires fire-rated tempered glass and ember-resistant door assemblies on every new opening. On one steep canyon parcel off Bear Creek Road, our crew replaced failed CWS 4000 Series double-hung and sliding-door units in a rebuilt home where fogged glass and warped frames were leaking during winter storms. We set new fire-rated tempered glazing, re-flashed the rough openings, and tied the window details into the defensible-space plan the owner needed for the rebuild permit. That’s the difference between a window swap and a CWS job done right for Boulder Creek’s actual rules.
If it’s not built right the first time, you’re just paying for it twice.
CWS Models & Products We Service in Boulder Creek
We work on CWS 4000 Series vinyl double-hung windows, common on the older redwood-and-cedar cabins that survived CZU. We also handle CWS Tempered Glazed Awning and Casement windows used on rebuilds, CWS sliding patio doors for decks and additions, and CWS fiberglass and steel entry doors for fire-hardened homes. Our Felton CWS service covers the same product lines. When OEM CWS glass, sash, and roller assemblies are still available for the model line, that’s what we use. When they’re discontinued, we use quality aftermarket hardware and tell you upfront. For 30-year-old vinyl units with warped frames and failed seals, we’ll say it straight: a fire-rated replacement makes more sense than tracking down obsolete parts.

FAQs – CWS Construction in Boulder Creek
Not necessarily, but any new window or door opening on a rebuilt or added structure in Boulder Creek must meet Chapter 7A fire-resistant assembly rules. Surviving windows on an existing home can stay, but if you’re replacing a failed CWS unit on a post-fire rebuild, expect to install fire-rated tempered glass and ember-resistant framing. We also handle CWS service in Lompico with the same fire-code expertise. Call (855) 473-5620 and we’ll tell you what your specific lot requires before you spend a dollar.
It depends on the track and roller condition. Boulder Creek decks collect redwood duff and ash grit that chews up CWS roller assemblies. We can often rebuild the rollers and re-align the track for a few hundred dollars. If the frame is warped or the glass is fogged, replacement is the smarter call. Get a free estimate at (855) 473-5620.
Fogged glass means the insulated glass unit seal has failed, usually from years of west-facing UV exposure and freeze-thaw cycles on Boulder Creek hillsides. A failed IGU counts against energy compliance when the county inspects a rebuild. We replace the IGU with OEM CWS glass where available. Call (855) 473-5620 for a quote.
Yes. We run smaller trucks and material deliveries for narrow private roads and long driveways common in Boulder Creek. We stage materials at the road when needed and carry them in. The access plan is part of the free estimate. Call (855) 473-5620.
Both can meet Chapter 7A when properly sealed and gasketed. Steel doors carry a heavier fire rating and resist ember intrusion at the threshold. Fiberglass holds up better to Boulder Creek’s damp winters and doesn’t dent as easily. We’ll spec the right one for your lot’s exposure. Call (855) 473-5620.
