CGI Construction in San Jose, CA | Viceroy Construction
Viceroy Construction provides independent CGI window and door service across San Jose, from single-sash repairs on 1960s Willow Glen ranches to full CGI unit replacements on new ADUs, including CGI repair in Buena Vista and nearby neighborhoods. We’re not a CGI dealer or authorized rep, which means when a fogged aluminum single-hung or a binding sliding patio door shows up, we diagnose it against the house itself, not a brand script. San Jose’s postwar ranch stock puts specific stress on CGI frames, seals, and tracks, and we’ve spent years learning exactly where those failures show up first. Call (877) 358-6557 for a free estimate on any CGI repair or replacement scope.
Why San Jose Residents Choose Us for CGI Service
Most window contractors in the South Bay know CGI as a product line. We know it as the window and door system that’s been sitting in San Jose stucco-over-wood-frame walls since before the 280 was finished. Neil Drummond grew up in the Saratoga foothills and trained in the building trades program at West Valley College, where framing, concrete, and structural work were taught as one continuous problem, not separate trades. That’s how we approach CGI service here. When a CGI aluminum single-hung fogs on the west side of a Rose Garden ranch, the window is only half the job. The flashing, the stucco reveal, the sill slope, and the way the original 1954 framing settled all matter. We pull the unit, see what’s actually failing, and then decide: OEM sash and glass if the frame’s sound, aftermarket balances if OEM’s discontinued, full replacement if the rot or seal failure has gone too far. One contractor owns that diagnosis from start to finish.
We carry OEM CGI replacement sash, glass, and hardware for the model lines still supported, and we keep a working stock of quality aftermarket balances, rollers, and weatherstripping for units where CGI parts are no longer made. That matters in San Jose because our schedule runs on the October-to-April rain window. When a slider starts binding in December, homeowners don’t have six weeks to wait on a backordered part. We get the door operating or we tell you plainly that replacement is the better spend before the next storm tracks in.

Common CGI Construction Problems We Solve in San Jose
- Fogged insulated glass on pre-1970 CGI aluminum single-hungs. San Jose’s dry season runs long and hot, and after 40 or 50 years of heat cycling, the glazing seals on original aluminum frames fail. The result is permanent fog between the panes on south- and west-facing windows. We replace the sash or the glass unit, and we check the frame channel for the corrosion that usually follows.
- Binding CGI sliding patio doors with fouled tracks and worn rollers. Winter rains wash dust and debris into the sill track, and decades of that grit grind rollers down until the door drags or jumps. This shows up constantly on orchard-era single-story homes where the original slider has been the main rear entry since the Eisenhower administration. We clean and re-set the track, replace rollers with OEM or aftermarket depending on availability, and re-align the door so it locks properly.
- Leaking CGI frames where stucco was never re-detailed after an addition or pop-top. San Jose’s redevelopment pressure means a lot of 1950s and 60s ranches have had second-story pop-tops or room additions grafted on. The new stucco meets the old CGI frame at a flashing joint that, too often, was never properly re-detailed. Water gets behind the frame, rots the rough opening, and drips into the wall cavity. We fix the flashing, repair or replace the opening, and reset the window so it sheds water the way the original install should have.
- Cracked or discolored CGI vinyl double-hungs on hard west and south exposures. San Jose ranch lots put west-facing walls in direct afternoon sun for six months straight. Cheaper vinyl from early mid-century retrofit jobs can chalk, discolor, or crack at the corners. When the frame’s still straight we can often replace just the sash. When it’s not, we quote a full unit replacement and install it with proper flashing.
- Undersized or mis-flashed CGI units in garage conversions and ADUs. We see a lot of San Jose garage conversions where a homeowner or a previous contractor cut a CGI window or door into a wall that was never designed for an opening. The header’s undersized, the flashing is backwards, or the unit was set too low. We re-scope the opening, size the CGI unit correctly, and pass inspection the first time.
CGI Service in San Jose: What Local Conditions Mean for Your Equipment
San Jose’s heritage-tree and tree-ordinance rules change how CGI window and door work gets planned here. A mature valley oak or redwood shading an older ranch lot in the neighborhoods west of downtown, including areas served by our CGI service in Alum Rock, is in many cases legally protected. You cannot remove it to add a bank of west-facing windows or to widen an opening for a sliding patio door without a city permit and an arborist review, and the city does not rubber-stamp those requests. That constraint shapes our CGI layouts from the first site visit. We plan window and door placements around trees that cannot legally come down, and we account for how a protected canopy affects light, heat gain, and stucco drying on the wall where the new units will sit. A generic CGI contractor sees a tree and grabs a saw. In San Jose, that’s a permit violation, a fine, and a stopped project. Our crew works the openings around what the city will and won’t allow, and the result is a layout that actually gets permitted and built.
CGI Models & Products We Service in San Jose
We service CGI aluminum single-hung and sliding windows common in San Jose’s 1950s through 1970s tract ranches, plus the vinyl double-hung replacement units that went into mid-century remodel updates over the last two or three decades. We also work on CGI sliding glass patio doors on orchard-era single-story homes and CGI window and door units specified for ADU and garage-conversion openings. For parts, we source OEM CGI replacement sash, glass, and hardware where the unit is worth keeping. When OEM is discontinued, we use quality aftermarket balances and rollers rather than leaving a window limping along. For full replacement scopes, we spec CGI units through our CGI sales & service supply relationships alongside PGT and Therma-Tru so the homeowner gets the right product for the exposure, not just the brand that was already there. If the frame is rotted or the seal is gone, we tell you plainly that replacement is the better spend.

AfterCGI Service Pricing in San Jose
CGI work prices in San Jose sit where labor, permit, and material costs for the South Bay land. A single-sash repair runs on the low end. Full-unit replacements climb with the opening count and the condition of the surrounding stucco and flashing. Here’s what we quote most often:
| Scope | San Jose Price Range |
|---|---|
| Window Replacement | $5,310 – $17,700 |
| Impact Window Installation | $9,440 – $29,500 |
| Kitchen Remodel (full scope, often includes CGI window work) | $16,520 – $53,100 |
What moves the number: how many openings, whether the stucco flashing needs re-detailing, whether a heritage tree forces a layout change, and whether we’re repairing or replacing the original units. A free estimate from us includes a written line-item scope, not a round number and a shrug. Call (877) 358-6557 to schedule one.

FAQs – CGI Construction in San Jose
Can you replace fogged CGI windows on a 1960s San Jose ranch without redoing the whole exterior? Yes, in most cases. We pull the affected sash or glass unit, replace it with OEM where available, and leave the surrounding stucco and framing intact if they’re sound. If the flashing around the opening was botched in a prior addition or pop-top, we fix that joint without touching the rest of the wall. Call (877) 358-6557 and we’ll tell you what your specific openings need.
Does a valley oak or redwood on my lot affect a CGI window or addition project in San Jose? It can. San Jose’s heritage-tree ordinance protects mature valley oaks and redwoods, and removing one or building a window wall under its canopy can trigger a city permit and arborist review. We plan CGI unit layouts around protected trees from the first site visit so your project gets permitted instead of stalled.
Are CGI aluminum windows in older San Jose homes worth repairing or should they be replaced? Depends on the frame. If the aluminum is straight, the channels aren’t corroded, and only the glazing seal failed, we repair with OEM sash or glass and you save real money. If the frame’s pitted, the thermal break is gone, or the rough opening is rotted, replacement is the better spend. We’ll show you the failure and let the numbers make the call.
When should we schedule CGI window and door work around San Jose’s rain season? The dry season, roughly May through October, is the easiest window. Winter rains complicate stucco patches, flashing work, and exterior caulking because everything needs dry substrate to cure. If a leak or a failed seal can’t wait, we can do interior sash and glass work in wet months and defer the exterior detailing to a dry stretch. Call (877) 358-6557 to get on the schedule before the next storm cycle.
Can CGI sliding patio doors be brought back to smooth operation? Usually, yes. Most binding sliders just need the track cleaned, the rollers replaced with OEM or a quality aftermarket set, and the door re-aligned so it locks without lifting. If the frame’s racked or the sill’s rotted, we’ll tell you that a new unit is the honest fix. Estimates are free.
