CGI Construction in Boulder Creek, CA | Viceroy Construction
We provide independent CGI construction services across Boulder Creek, CA, from fiber-cement siding and trim work to full exterior re-clads on Chapter 7A rebuilds. The difference here isn’t just product knowledge. It’s knowing how a CGI assembly actually performs on a steep, forested lot where the county reviews every detail for wildfire defensibility. If you’re looking at a siding repair, roof replacement, or home addition in Boulder Creek, call (877) 358-6557 and we’ll help you sort out what the project really needs.
Viceroy Construction handles the full construction scope under one contract, so you’re not chasing a siding crew, a roofer, and a carpenter through three different phone numbers. We’re a general contractor with direct experience in Boulder Creek’s specific permitting reality, and we work with CGI’s fiber-cement product lines among a broader portfolio of brands like James Hardie, GAF, and Therma-Tru. For more on our CGI work specifically, see our CGI sales & service page.
Why Boulder Creek Residents Choose Us for CGI Service
Most contractors in the valley can install fiber-cement siding. Fewer understand what CGI trim and lap profiles do when they’re exposed to Boulder Creek’s particular combination of winter rain, summer wildfire smoke, and shaded north-facing walls where redwood duff never fully dries out. We do, because we’ve rebuilt and remodeled homes throughout the Boulder Creek service area under unincorporated Santa Cruz County review, where Cal Fire Chapter 7A compliance isn’t optional. It’s the starting line.
Neil Drummond, our owner, trained in the building trades program at West Valley College in Saratoga, with hands-on coursework in framing, concrete, and structural work. That background means when we scope a CGI exterior on a sloped Boulder Creek lot, we’re thinking about load paths, drainage, and fastener corrosion from the first site visit, not just which product box to order from. For homeowners nearby, CGI service in Ben Lomond follows the same careful approach. The details you don’t see are the ones that matter most.

Common CGI Construction Problems We Solve in Boulder Creek
- Bottom-course delamination on sloped lots. CGI fiber-cement siding installed tight to grade or roof-to-wall junctions wicks groundwater during heavy winter rain and delaminates at the bottom course. On Boulder Creek’s steep terrain, that’s not a cosmetic issue. The exposed edge becomes a moisture path into the sheathing.
- Chalking and cracking on sun-exposed trim. Factory paint and field-cut edges left unsealed on CGI trim crack and chalk faster under intense summer sun and wildfire smoke exposure. Properties on south-facing slopes above the San Lorenzo Valley see this accelerate faster than shaded canyon lots.
- Corroded fasteners on shaded walls. Fasteners that aren’t corrosion-rated fail where redwood and tanoak debris traps moisture against panels on north-facing walls. We see this regularly on older mountain cabins where someone used standard exterior screws years ago.
- Ember-entry gaps at decks and vents. Panels butted without proper clearance at decks and vents create ember-entry gaps that don’t meet Chapter 7A detailing on CZU rebuilds. County inspectors look for this specifically on Boulder Creek projects.
- Flashing failures at wall-to-deck junctions. On a CZU rebuild off a private road in the Boulder Creek hills, our crew found previous CGI fiber-cement lap siding butted tight to the new deck ledger with unsealed field cuts, trapping rain against the sheathing. We pulled the bottom courses, replaced the soft sheathing, re-detailed the junction with Chapter 7A-compliant flashing and ember-resistant venting, and re-clad with sealed CGI trim so the assembly would pass county review.
CGI Service in Boulder Creek: What Local Conditions Mean for Your Equipment
Because Boulder Creek reviews run through unincorporated Santa Cruz County rather than a city building department, and many lots sit on narrow private roads, a CGI-clad addition or rebuild often can’t be permitted until the plans show a fire engine can physically reach the driveway and turn around. That single requirement changes how we approach exterior work here. You can’t just swap like-for-like siding on a legacy cabin and assume the permit will clear. The county wants to see the whole assembly: siding clearances, vent detailing, roof-to-wall transitions, and emergency access. On homes along narrow spurs off Highway 9 or winding roads with no pullouts, the driveway geometry sometimes drives the scope of the CGI work as much as the condition of the existing cladding. We’ve had projects where the siding was in decent shape but the permit couldn’t move until we reworked the access path, trimmed back tanoak overgrowth, and documented the turnaround radius. That’s Boulder Creek-specific work, not something a generic siding crew from over the hill deals with.
CGI Models & Products We Service in Boulder Creek
We work with CGI’s exterior cement-fiber siding and trim profiles, including fiber-cement lap and panel siding for WUI assemblies, soffit and fascia components, and deck and trim boards used in fire-resistive exterior packages. We also provide Felton CGI service with the same product range. On repairs, we use CGI’s own trim and siding components where the assembly and finish warranty depends on it, and quality corrosion-rated fasteners and sealants from proven suppliers everywhere else. On older mountain cabins with sound framing, we repair and re-clad rather than tear off good structure. On fire-damaged or rotted sheathing, we recommend full replacement so the WUI assembly is correct from the studs out. That’s a judgment call we make on site, not over the phone with a script.

AfterCGI Service Pricing in Boulder Creek
What drives cost on our Home Remodeling in Boulder Creek involving CGI is access, slope, and the condition of what’s underneath the siding. A straightforward re-clad on a level lot with easy driveway access lands differently than a hillside rebuild requiring scaffolding and debris removal off a narrow private road. Here’s what we typically see:
| Project Type | Price Range |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Metal Roof Installation | $15,000 – $40,000 |
| Full Bathroom Remodel | $9,000 – $28,000 |
| Walk-In Shower Installation | $4,500 – $12,000 |
| Home Addition | $45,000 – $130,000 |
Every estimate is free and line-itemed. We walk the site, look at what’s actually happening with the framing and drainage, and give you a written number before any work starts. Call (877) 358-6557 to schedule yours.

FAQs – CGI Construction in Boulder Creek
Yes. Boulder Creek is in a designated wildland-urban-interface zone, and unincorporated Santa Cruz County enforces Chapter 7A building standards for new construction and additions, including exterior siding, vents, and roof assemblies. Your plans won’t clear review without WUI-compliant material specs on the elevations. Call (877) 358-6557 and we’ll walk you through what the county will actually require.
Because the county checks whether a fire engine can access and turn around on your property before they’ll sign off on an addition or substantial remodel. If your driveway geometry doesn’t clear the access standard, the CGI scope often has to be sequenced with access improvements, tree removal, or turnaround grading. We coordinate this as our General Contractor in Boulder Creek would, managing all trades together. We factor that into the estimate from day one.
In many cases, yes. If the framing is sound and the damage is limited to bottom courses or isolated field cuts, we repair with CGI’s own trim and siding components and seal the new edges properly. If the sheathing behind the siding is rotted or the panel clearances don’t meet current WUI detailing, full replacement is the safer call. We’ll show you what we found and explain the reasoning before you commit.
CGI fiber-cement siding is a legitimate material for WUI assemblies and holds up better than wood or vinyl under ember exposure. But the material is only as good as the installation detailing. Gaps at decks, vents, and roof-to-wall junctions are where embers get in, and those details are exactly what Boulder Creek inspectors check under Chapter 7A. The product works; the installation is what passes inspection.
Rain drives the failure we see most often on Boulder Creek hillsides: moisture wicking into unsealed bottom edges and field cuts, then delaminating the panel from the substrate. Proper clearance above grade, sealed cuts, and correct flashing at roof-to-wall transitions prevent it. If you’re seeing swelling or chalky edges, call (877) 358-6557 for a free inspection before the damage moves into the framing.
