If you need CGI windows or doors serviced or replaced in Palo Alto, call (844) 681-3590 for a free estimate.
CGI is one of the brands our crews handle constantly in Palo Alto General Contractor gut-renovation and second-story work. We know its window and door lines, how they behave in seismic-detailed walls, and which flashing and anchoring details hold up under real inspection. We are an independent contractor and not authorized, sponsored, or endorsed by CGI. Our credibility comes from field experience with the product, not from a factory badge.

Why Palo Alto Residents Choose Us for CGI Service
Palo Alto homes are different from what you’ll find ten miles south. Older pre-1950s stock, mid-century Eichler-era tracts, and newer infill all sit on tight lots where mature coast live oaks and redwoods push right up against the structure. That changes how a window or door job goes, because the rough opening you’re working with was often framed decades ago for a unit that no longer exists.
We’ve done CGI work in enough Palo Alto homes to know what we’re opening up before we cut the first bead of caulk. Sill pans that were never installed. Weatherstripping that shrank in the dry summer sun. Fogged dual-pane glass on units that are otherwise sound. Noel Carbajal, our owner, has spent almost thirty years building and remodeling across California, and his rule on window work is simple: the rough opening gets fixed before the new unit goes in. Otherwise you’re just hiding the problem behind a new frame.
We use OEM CGI replacement sashes, glass units, and hardware where the frame and sill are sound, and quality aftermarket weatherstripping and rollers where the OEM part is discontinued or adds weeks to a tight schedule. That matters in Palo Alto, where a permit timeline is already long enough without waiting on a backordered part from Florida.

Common CGI Construction Problems We Solve in Palo Alto
- Seal and glazing failures on west and south-facing CGI vinyl units. Palo Alto’s dry, high-UV summers cook older vinyl frames and shrink weatherstripping to nothing. By the time winter rain arrives, the sash doesn’t seal, and late-summer smoke has already been filtering through. We replace the weatherstripping and reglaze where the frame is sound, and swap the whole sash where it isn’t.
- Sill pan and flashing omissions behind CGI sliders and patio doors in pre-1950s remodel walls. The original rough opening was never detailed for a modern flanged unit. The leak shows up in the first real winter rainstorm, not at install. We pull the unit, rebuild and flash the sill correctly, and reset it so water drains outward instead of into the wall sheathing.
- Fogged dual-pane insulated glass units in mid-century Eichler-era tracts. When the thermal pane seal fails, moisture gets between the glass and you’re looking through a permanent haze. The fix is glass replacement, not a whole new window, and we handle that regularly without triggering a full frame replacement.
- Hardware and roller failures on CGI patio and sliding doors on tight lots. When the slider is the main path to the yard and gets cycled dozens of times a day during construction and after, rollers wear out fast. A door that drags or jams on the track is a roller and hardware job most of the time, and we stock common replacement parts locally.
- Bowed or racked frames from seismic settling. Older Palo Alto homes move, especially after decades of minor settling and the occasional shaker. A CGI window that won’t latch or a slider that binds at the top tells you the frame has racked. In those cases, the honest answer is replacement, not patchwork.
CGI Service in Palo Alto: What Local Conditions Mean for Your Equipment
Here’s what makes Palo Alto genuinely different for CGI owners, and it’s not the weather. It’s the city’s permitting and arborist review process. Change a rough opening on a tight lot, and your window or door schedule can sit behind sight-line, privacy, and coast live oak root-protection review before the permit is issued. We’ve seen projects in the Professorville area near 94301 stall for weeks over a mature oak’s root zone because the original window opening needed to shift eighteen inches for a code-compliant egress path. So our crews order CGI units only after the approved plan set matches the actual rough openings we template in the field. We don’t order first and hope. We measure twice against the stamped drawings, then order once.
That discipline matters because CGI windows and doors are built to a specific size and flashing detail. If the plan changes after the units arrive, you’re not just dealing with an aggravated building official. You’re dealing with a homeowner who can’t close in their second story until the right unit shows up. We’d rather spend the extra week templating than the extra month reordering.
CGI Models & Products We Service in Palo Alto
We service the full residential CGI line we see in Palo Alto homes, plus Emerald Lake Hills CGI service: Sentinel vinyl single-hung and slider windows, Classic vinyl double-hung and casement windows, CGI patio doors and sliding glass doors, and vinyl picture and awning units. The Sentinel sliders show up constantly on Eichler-era patio walls. The Classic double-hungs are the workhorses in older single-family remodels.
Our parts approach is straightforward. We use OEM CGI sashes, glass, and hardware when the frame justifies it and lead times allow. Where an OEM part is discontinued or would slow a permit-driven schedule, we use quality aftermarket weatherstripping and rollers that hold up just as well. We’re upfront about which is which, and our estimate tells you before we touch the work.

FAQs – CGI Construction in Palo Alto
If the frame is square and the sill pan is intact, we replace just the insulated glass unit. That’s the standard fix for fogged dual-pane glass in Eichler-era homes and pre-1950s remodels. The full unit only gets replaced when the frame is bowed, the sill was never flashed properly, or the wall is being opened anyway for seismic or addition work. Call (844) 681-3590 and we’ll tell you which applies after one look.
It can, especially if the opening changes size or the new unit faces a neighbor. Palo Alto’s planning and arborist review means sight-line, privacy, and coast live oak root-protection concerns can send a changed window or door schedule back for review. We template the openings against the approved plan set before ordering, so you’re not fighting the permit process after the units arrive.
Most likely the weatherstripping has shrunk from decades of dry summer heat, or the sill pan was never detailed correctly when the windows went in. Sometimes both. The fix starts with pulling the unit, inspecting the rough opening flashing, and resetting or replacing from there. Call (844) 681-3590 for an exact diagnosis and a written estimate.
Yes. We do CGI window and door installation as part of full second-story additions, ADU construction, and whole-home remodels across Palo Alto and CGI in Los Altos Hills. Since the unit schedule has to be coordinated with the structural opening and the approved plan set, it’s cleaner to have one contractor handling both the framing and the window install. That’s how we work.
No. Framework Contractors is an independent contractor and is not authorized, sponsored, or endorsed by CGI. We use OEM CGI parts where the job calls for them, but our service doesn’t flow through CGI’s factory warranty program. What you get from us is field experience with the product and a written workmanship warranty on our installation.
