CGI Construction in San Jose, CA | Penhallow Remodeling San Jose
We provide independent CGI service across San Jose, from our Bathroom Remodeling in San Jose that includes new CGI impact windows to full roof replacements. What sets our work apart here is that we understand how San Jose’s aging stucco-on-slab homes and seismic retrofit needs interact with CGI’s specific frame designs. We’re not a manufacturer branch or an authorized dealer. We’re a local remodeling contractor that installs and services CGI products correctly, with a written price and a 365-day guarantee on every job. Call (669) 274-2362 for a free estimate.
Why San Jose Residents Choose Us for CGI Service
Our crew has rebuilt and retrofitted CGI windows and doors across San Jose’s aging ranch and Eichler-inspired homes, so we know the exact frame and flashing details these models need in a seismic retrofit. Trevor Nash, who runs our San Jose operation, picked up his first framing hammer on a Los Angeles summer job before studying the craft at LA Trade-Technical College, and he’s spent the better part of two decades running remodeling projects across the South Bay. That includes a stretch of kitchen and bath gut-jobs in Willow Glen, where he worked as a General Contractor in San Jose, that he still considers some of his cleanest finish work. When a homeowner asks about CGI, we talk about real things: wind-load ratings, stucco returns, roller wear, and whether a repair makes sense or replacement is the wiser spend.
We operate under The Kingswell Way, which since 2004 has meant three things: say the price before the work, show up in the window we gave, leave the place cleaner than we found it. Every CGI-related job gets a written number before a single tool leaves the truck, and the 365-Day Done Right Promise is in writing on every project. If something fails inside that year, we come back and fix it at no charge. No service call, no re-inspection fee. A live person answers our phone 24/7, and every technician is background-checked and arrives in uniform.

Common CGI Construction Problems We Solve in San Jose
- Failed insulated glass seals on south-facing CGI Sentinel Series windows. San Jose’s dry Mediterranean climate means months of strong sun, and homeowners in Willow Glen often run sprinklers that overspray onto window glass. The repeated heating and cooling, plus mineral deposits from the water, breaks down seals faster than you’d expect. We replace the glass unit with OEM CGI seals to preserve the impact rating.
- Warped or stuck CGI sliding door rollers. Long rainless summers in San Jose leave a fine dust and pollen in the air, and months of that grit works its way into CGI 8800 Series sliding glass door tracks. By August, rollers seize and the door drags or jams. We disassemble, clean, replace rollers, and re-shim the frame if the slab has settled.
- Leaking CGI window frames on east-side tract homes. Original stucco on homes built in the 1950s and 1960s cracks as adobe soil expands during winter rains. Water gets behind the stucco and finds the window frame. We re-flash the rough opening and seal the CGI frame correctly, so the leak stops at the source, not at the caulk line.
- Bowed CGI mullions on wide picture windows in Eichler-inspired homes. Concrete slab foundations settle during drought years, and that slight movement puts stress on wide window assemblies. You’ll see a mullion bow or a corner seam open. We re-shim the frame and, where needed, machine an aluminum adapter to restore a square, sealed fit.
- Hard-cranking CGI casement windows after rainy season. CGI CWS 50/60 casement windows collect fine silt and grit in the operator mechanism. When winter rain hits, that grit turns to paste. We strip the operator, clean it, and re-lubricate with the right hardware, so the crank turns smooth again.
CGI Service in San Jose: What Local Conditions Mean for Your Equipment
Many San Jose homes built between 1950 and 1970 used single-pane aluminum windows, and when owners upgrade to CGI impact windows as part of a kitchen or bath remodel, we often have to re-flash the entire rough opening because the original stucco returns were never designed for the thicker CGI frame. This is a San Jose-specific issue. In a newer city with vinyl siding or different construction, a simple window swap might work. Here, the stucco needs to be cut back, a new flashing system installed, and the frame set at the right depth. Skip that step and you’ll get a window that looks fine for a year, then leaks at the first heavy winter rain. On east-side tract homes near Alum Rock, where original copper wiring has also gone brittle from decades of heat, we coordinate the window retrofit with any electrical work so the rough opening gets opened once and closed correctly. Trevor’s rule applies here: “Give me the real problem and I’ll give you the real number.”
CGI Models & Products We Service in San Jose
We service the full residential CGI line: Sentinel Series impact windows, Estate Collection windows, CWS 50/60 casement windows, and 8800 Series sliding glass doors. For parts, we use OEM CGI seals, rollers, and hardware whenever possible to preserve the original wind-load and impact ratings. If the OEM part is backordered, we’ll machine a mill-finish aluminum adapter or use a higher-grade aftermarket seal, and we’ll tell you exactly what we’re doing and why. Older CGI units with obsolete parts sometimes aren’t worth patching. We’ll say so straight, and give you a written replacement price alongside the repair quote so you can compare. Our San Jose service area means quick turnaround on parts and scheduling. For homeowners in neighboring cities, we cover Santa Clara County broadly. See our San Jose service area for full coverage.

FAQs – CGI Construction in San Jose
No. A stucco warranty on a 1950s-1970s San Jose home is almost certainly expired, and any remaining builder warranty would not be voided by a correctly installed CGI window. What matters is how the rough opening is flashed and resealed. We cut the stucco cleanly, install proper flashing, and patch the return with a compatible stucco mix. Done right, the new seal outlasts the old one. Call (669) 274-2362 and we’ll walk you through what your specific home needs.
Yes. The dark bronze finish on CGI Estate Collection windows is very close to the original anodized aluminum used on Eichler homes. Where there’s a slight difference, we use a mill-finish adapter or a matching trim that blends the transition. We’ve done this on several Eichler-inspired homes in San Jose, and the finished look reads as continuous, not patched.
It is. San Jose’s long dry season puts fine dust and pollen in the air, and it settles into the operator mechanism of CWS 50/60 casement windows. When winter rain arrives, that grit turns to a paste that stiffens the crank. We strip the operator, clean it, and re-lubricate with the correct hardware. It usually takes under an hour per window. Call (669) 274-2362 to schedule a quick assessment.
It depends on the window’s exposure and your long-term plans for the home. A small bathroom remodel in San Jose runs $5,900 – $14,160, and adding a CGI impact window might add $1,500 – $3,000 depending on size and model. If the bathroom window is south-facing or on a wall that gets full sun, the impact glass and a proper frame seal will pay off in lower cooling costs and fewer future repairs. We’ll give you a written quote for both options so you can decide with real numbers.
All the time. We pulled a failed CGI 8800 Series sliding glass door from a ranch house in Willow Glen last August. The rollers were completely seized with a paste of fine dust and pollen from the long dry spell, and the homeowners had resorted to lifting the door out of its track. We disassembled the header, vacuumed the track, replaced the OEM rollers, and re-shimmed the frame after the stucco had settled, so the door now glides and seals tight. If the frame is sound and the glass is intact, repair is almost always the better value. Call (669) 274-2362 for a free repair estimate.
