CGI Construction in Whittier, CA | Sawyer Remodel West Covina
We’re Sawyer Remodel West Covina, and we provide independent CGI window, door, and curtain wall service across Whittier. We are not a CGI dealer or manufacturer affiliate. What makes our CGI work different here is that we pair impact-rated product knowledge with Whittier’s specific hillside drainage and seismic retrofit requirements, so the window or door you install actually holds up to both high wind and the ground shifting beneath it. If you need CGI service in Whittier, call (341) 217-4204 for a free estimate.
Why Whittier Residents Choose Us for CGI Service
Whittier’s housing stock runs from 1920s Spanish Colonial Revival bungalows in the flats to 1960s and 70s hillside custom homes that predate modern seismic codes. Our crews have rebuilt and retrofitted CGI windows, doors, and curtain wall systems on hundreds of Whittier hillside and flatland homes. That means we know CGI’s hurricane-rated product lines from the inside out, without any manufacturer affiliation. Luca Romano, owner of Sawyer Remodel West Covina, grew up in East Los Angeles and trained in construction technology at Los Angeles Trade-Technical College. He’s spent two decades doing the kind of work that holds a house together, framing, tile, full kitchen and our Bathroom Remodeling in Whittier overhauls. Good work shows. Bad work shows up later. When you call us about a CGI window that’s fogged or a slider that binds, we show up knowing what we’re looking at.
We’re also part of the Relay Home Co. family, founded in 2005. Every project runs under The Relay Visibility Guarantee: a written price before work starts, live arrival time tracking, and before-and-after photo updates. No exceptions. Our technicians are background-checked and uniformed. You know who’s walking into your Whittier home before they arrive. And when you call, a live person answers, 24/7. No voicemail loops.

Common CGI Construction Problems We Solve in Whittier
- Fogged impact glass on south-facing hillsides. Whittier’s hot, dry summers and extreme diurnal temperature swings put real stress on older CGI Estate Collection windows. The seals fail, desiccant saturates, and the glass fogs permanently. We replace the insulated glass unit with genuine CGI laminated glass, not a generic substitute that voids the impact rating.
- Binding CGI sliding doors on settled hillside foundations. Many post-1980 hillside homes in Whittier have settled unevenly. That throws CGI slider tracks out of alignment, causing binding and air or water infiltration. We re-level the track, replace worn rollers with CGI-spec hardware, and address the flashing so water stops getting in.
- Corroded hardware near the marine layer. Whittier sits close enough to the coast that the marine layer creeps in overnight. On older CGI installs where stainless steel hardware was never isolated from dissimilar metals, galvanic corrosion eats the fasteners. We replace with properly isolated stainless hardware and re-seal every penetration.
- Rotted wood bucks on 1920s – 1950s homes. Whittier’s older Craftsman and Spanish Colonial homes often have original wood rough openings around CGI windows. When winter rains hit, old flashing details fail, the wood rots, and the window’s air and water barrier is compromised. We pull the unit, replace the buck with pressure-treated lumber, install new stainless flashing, and reset the window properly.
- Failed weatherstripping on CGI Estate Collection doors. Santa Ana winds in Whittier push fine dust and hot air against exterior doors. Worn weatherstripping on CGI sliders and swing doors lets that in. We replace with genuine CGI weatherstripping so the seal actually matches the frame profile.
CGI Service in Whittier: What Local Conditions Mean for Your Equipment
Whittier’s Hillside Management Ordinance requires engineered drainage and retaining plans for any exterior remodel on slopes over 15%. That directly affects how we flash, waterproof, and anchor CGI window and door openings on hillside homes. You can’t just pop out an old window and set a new one in, not on a slope the city has flagged. We have to account for surface water, subsurface water, and the fact that the hillside itself is moving a little every year. Our crew replaced eight original CGI Estate Collection fixed windows on a 1968 ranch on Painter Avenue, where the homeowners had lived with fogged glass and a rusted mullion for years. We removed the failed sashes, upgraded the rough openings with new pressure-treated bucks and stainless steel flashing, and installed new CGI Estate Collection impact units. We finished by resealing the exterior stucco reveals to match the original Spanish Colonial texture and left the homeowner with a tight, clear view of the Whittier Hills. That’s a compliance layer no flatland city page addresses, and it’s why CGI work in Whittier costs what it costs and takes the time it takes.
CGI Models & Products We Service in Whittier
We service the full CGI sales & service lineup that shows up in Whittier homes. That includes CGI Estate Collection impact windows, CGI Estate Collection sliding glass doors, CGI Sentinel Series casement and awning windows, and CGI Targa Series impact-rated units built for coastal and high-wind zones. We always specify genuine CGI replacement glass, hardware, and weatherstripping when available. CGI’s proprietary laminated glass and interlocking components are engineered to work as a system. Aftermarket substitutes often void impact ratings. For out-of-production CGI models, we source NOS or exact-spec aftermarket parts only when OEM is unavailable, and we always tell the homeowner if a full replacement is safer than a patch. We keep common CGI hardware and weatherstripping in local stock so most Whittier repairs don’t wait on a freight shipment.

What drives the cost in Whittier is the hillside factor. If your home is on a slope over 15%, we’re dealing with engineered drainage, retaining plans, and possibly scaffolding on a grade. That adds labor hours and sometimes engineering review. Flatland homes are simpler. Either way, as your General Contractor in Whittier, you get a written price before any work starts.

FAQs – CGI Construction in Whittier
We pull the permit and submit the drainage and retaining plans the city requires for any exterior remodel on a slope over 15%. We coordinate with the city’s plan check, we schedule the inspections, and we don’t start cutting into the rough opening until the permit is approved. You don’t chase paperwork. Call (341) 217-4204 and we’ll walk you through what your specific property triggers.
Yes, in most cases we can replace just the insulated glass unit with genuine CGI laminated glass while keeping the existing frame. If the frame is rusted, warped, or the mullion is compromised, we’ll tell you honestly whether a full replacement is safer. We don’t patch a window that’s already past saving.
Hillside foundations settle unevenly, and that throws the slider track out of alignment. The door starts binding at one end, then air and water get past the weatherstripping. We re-level the track, replace rollers and hardware with CGI-spec parts, and fix the flashing so the opening drains correctly. Call (341) 217-4204 for an exact quote, estimates are free.
In most cases, replacing a window in an existing opening does not require a permit, unless the home is on a hillside slope over 15% and the city requires drainage review. We check before we quote. If a permit is required, we pull it and pass the inspections.
Yes. CGI offers frame profiles and exterior finishes that read clean and simple, which suits Craftsman and Spanish Colonial homes better than bulky vinyl alternatives. We match the exterior stucco reveal and trim detail to the original, so the new impact window looks like it belongs, not like it was bolted on.
