CGI Construction in Mountain View, CA | Viceroy Construction
We provide independent Mountain View General Contractor CGI construction service across Mountain View, including Waverly Park, Monta Loma, downtown, and North Bayshore. Our crews handle CGI exterior wall assemblies, rainscreen cladding, storefront framing, architectural trim, and prefabricated envelope panels without the markup or scheduling delays of a manufacturer’s own service division. The thing that makes our CGI work here different: we know how these systems fail on Mountain View’s specific housing stock, especially the Eichler tracts where original radiant slabs sit directly beneath every repair we make. Call (877) 358-6557 for a free estimate.
Viceroy Construction is an independent general contractor, not an authorized CGI dealer. That independence means we specify parts based on what the job needs, not what a manufacturer mandates. And our CGI sales & service work is backed by the same single-contractor accountability we bring to every remodel, roof, and addition we run across the South Bay.
Why Mountain View Residents Choose Us for CGI Service
CGI systems live or die at the transitions: wall-to-roof, panel-to-flashing, metal-to-dissimilar-metal. Those are exactly the points that fail on Mountain View’s mid-century homes and infill facades. Our crews have spent years on both, and we’ve seen how the dry-season-to-wet-season swing works fasteners loose on flat Eichler roofs and North Bayshore curtain walls alike.
Neil Drummond, who runs Viceroy Construction, cut his teeth on post-and-beam framing and structural work at West Valley College in Saratoga before spending the better part of three decades on South Bay remodels and additions. That background matters when a CGI cladding repair requires opening up a 1950s wall that is not plumb, or when a rainscreen detail sits six inches above a copper radiant line. The details you don’t see are the ones that matter most.
Residents also choose us because we stock OEM-compatible CGI components and matched-quality aftermarket trim locally, which means faster turnaround than a distributor delaying on a manufacturer-issued part.

Common CGI Construction Problems We Solve in Mountain View
- Differential thermal cycling at low-slope roof transitions. Mountain View’s dry summers and wet winters subject CGI metal flashing to repeated expansion and contraction. On Eichler roofs in Waverly Park and Monta Loma, original built-up and low-slope transitions concentrate that movement, and we regularly see fasteners backed out and sealant joints split where a newer CGI flashing ties into a 60-year-old roof membrane. We strip, re-detail, and re-seal those junctions rather than caulk over the problem.
- Galvanic corrosion on North Bayshore facades. The wet-season wind drives rain against mid-rise facades along Shoreline and the Bayshore corridor, and CGI aluminum components bolted to steel or other dissimilar metals start corroding where the protective barrier is scratched or the isolation gasket is missing. We inspect for that specific failure before recommending a repair scope, because a quick patch over active galvanic deterioration only buys one season.
- Water infiltration at CGI panel joints that were never detailed for Santa Clara Valley storms. Roof and facade assemblies that shed a normal winter’s rain can still fail when wind-driven water pushes sideways into joints that were caulked but never gasketed. We re-detail CGI panel and flashing interfaces with a weather-tight seal designed for the Valley’s actual exposure, not a generic dry-climate spec.
- Fastener back-out on post-and-beam walls that are not perfectly plumb. Eichler-era framing rarely sits dead true. Original 1950s post-and-beam construction shifts and settles, and CGI components fastened to it slowly work themselves loose. A tighten-up-and-caulk fix fails within a season or two. We remove, true the mounting line where the framing allows, and re-install with appropriate fasteners and isolation.
- Slab-damage risk during any CGI repair that touches the ground plane. In Waverly Park and Monta Loma, every trench, footing line, or penetration near the original radiant floor slab is a liability. We run a pre-construction scan and hand-dig around slab areas on nearly every job in those tracts, because puncturing a 1950s copper line during an envelope repair is an expensive, entirely avoidable mistake.
CGI Service in Mountain View: What Local Conditions Mean for Your Equipment
Here is the information most CGI pages never give you. Mountain View’s west-side Eichler tracts, including Waverly Park and Monta Loma, hold original 1950s radiant floor slabs with copper piping that can be punctured during foundation work or remodel trenching. On any job there, including CGI envelope or flashing repairs near a slab, we run a pre-construction slab scan and hand-dig before we touch anything below grade. That single step changes how a job is scoped, priced, and sequenced, because a punctured copper line beneath a finished floor turns a $1,500 flashing repair into a multi-day plumbing and slab repair.
That hazard is not present in CGI in Sunnyvale‘s younger ranch tracts or Palo Alto’s varied housing stock, and it is one reason our crews sequence CGI work differently in Mountain View than anywhere else. We also schedule envelope and roof-related CGI work before the first significant fall rains, when sealant and flashing installations have the dry conditions they need to cure correctly.
CGI Models & Products We Service in Mountain View
We work on CGI exterior wall and rainscreen cladding assemblies, the kind used on mid-rise infill buildings around downtown and North Bayshore. We service CGI commercial storefront and curtain-wall framing components, architectural metal trim and flashing systems, and prefabricated building envelope panels. That coverage spans a range of façades, from Waverly Park Eichler wall details to North Bayshore mid-rise elevations.
For parts, we use OEM CGI components where they are available and structurally appropriate. When an OEM lead time would stall a weather-tight schedule, we specify matched-quality aftermarket parts for non-structural trim and accessories. We will tell you plainly whether a CGI assembly can be repaired and re-sealed, or whether a section should be replaced outright.

What drives the cost on a CGI-specific repair: whether the assembly was installed on a true, plumb mounting line or an out-of-plumb Eichler wall, whether there is active galvanic corrosion at the metal interfaces, and whether slab scanning and hand-digging are required. A free estimate includes a visual inspection, a written scope, and a fixed price for the work we propose. Call (877) 358-6557 to put one on the calendar.

FAQs – CGI Construction in Mountain View
Yes. We run a pre-construction slab scan on nearly every Waverly Park and Monta Loma job before we dig, trench, or set any footing line near the original 1950s radiant slab. If work must happen near the slab, we hand-dig around the copper piping rather than run a machine, which protects the line and keeps the repair isolated to the CGI assembly itself.
Yes, and we recommend scheduling it that way. Mountain View’s wet-season rains arrive in late fall, and CGI flashing, sealant, and panel installations need dry conditions to cure and bond properly. Call (877) 358-6557 to get on the schedule before the first storms roll in.
No. Viceroy Construction is an independent general contractor. We are not authorized, sponsored, or endorsed by CGI, which means we specify OEM CGI parts where they are structurally appropriate and matched-quality aftermarket parts where lead times or cost justify it. You get an honest repair-or-replace recommendation, not a manufacturer script.
They hold up well when they were detailed for wind-driven rain and dissimilar-metal isolation. Where we see failures, it’s usually galvanic corrosion at CGI-to-steel interfaces, or sealant joints that were never gasketed. We inspect those specific points before recommending any repair, because the Bayshore’s exposure is different from the west side’s more sheltered lots.
Often, yes. If the mounting line is still true, the panels are intact, and the corrosion is confined to non-structural trim, we can re-seal, re-flash, and re-fasten in place. If the assembly has pulled away from an out-of-plumb Eichler wall or the galvanic damage has reached the structural connections, we will tell you plainly that replacement is the better use of your money. Call (877) 358-6557 for an honest evaluation.
