CGI Construction in Poway, CA | Mason Remodeling Co San Diego
We provide independent CGI window, door, and siding service across Poway, from 1970s tract homes west of Community Road to horse properties off Highway 67. The one thing that makes our CGI work here different: we know that replacing a window east of Espola Road on a pre-1990 home can trigger mandatory shear wall upgrades, so we price and plan for the retrofit before we touch the opening. Our crews have worked on CGI 950 Series impact windows, Estate Collection units, and 800 Series sliding doors throughout Poway for years. Call (619) 673-9302 for a written estimate before any work starts.
Why Poway Residents Choose Us for CGI Service

We’re not a manufacturer affiliate. We’re an independent CGI service provider, which means we tell you the truth about what a repair costs versus what a replacement should cost, without a factory rep standing over our shoulder. That matters in Poway, where the housing stock spans original 1979 ranchers and recent custom builds, and where CGI products age differently depending on which side of the valley they sit on.
Isaac Pruett, owner of Mason Remodeling Co San Diego, grew up in Los Angeles and learned framing before he ever sat in a classroom, then sharpened his craft at LATTC. For the past several years, he and his crew have worked across San Diego County, and they’ve spent enough time in Poway to know which CGI lines hold up under inland heat and which need retrofit attention before a remodel triggers code upgrades. Every technician who arrives at your door is background-checked, identity-verified, uniformed, and introduced by name and photo before the visit. That’s The Threshold Standard, and we don’t waive it.

Common CGI Construction Problems We Solve in Poway
Here’s what we see most often on CGI products in Poway, and why it happens here specifically:
- Fogged glass from thermal seal failure. Poway’s summer heat bakes dual-pane CGI units, and after 15 to 25 years the seal between the glass panes gives out. You’ll see condensation or haze between the glass that won’t wipe off. We saw this on a 1979 rancher off Twin Peaks Road when a fogged CGI 950 Series picture window had lost its seal from years of inland heat.
- Warped or sticking sashes on west-facing walls. Afternoon sun in Poway is relentless, and aluminum CGI frames on west exposures expand and contract enough to make sashes bind or stick. Dry heat accelerates it. The fix is usually sash adjustment or replacement, not a full frame swap.
- Faded or chalky powder coat on exposed frames. East-side Poway properties with no mature shade trees get intense UV, and older CGI powder coat breaks down into a chalky residue that rubs off on your hand. It’s cosmetic but it signals the frame has been cooking for decades.
- Roller and track wear on heavy CGI sliding doors. Poway’s equestrian properties track grit and dust onto door tracks, and CGI 800 Series sliding doors are heavy. Worn rollers make them drag, jump the track, or refuse to latch. We replace rollers and weatherstripping with quality aftermarket equivalents when they don’t affect the impact rating.
- Undersized shear wall discovery during window work. This one isn’t a CGI part failure, but it shows up constantly on pre-1990 Poway homes. Pull a permit for an opening east of Espola Road and the inspector often flags the shear wall. We plan for it up front so you’re not surprised mid-job.
CGI Service in Poway: What Local Conditions Mean for Your Equipment
East of Espola Road, it’s common to find original 1970s wood shake roofs and undersized shear walls that trigger mandatory upgrades the moment a homeowner pulls a re-roof or addition permit. For CGI owners, that means a window replacement is rarely just a window replacement. On a pre-1990 home in that part of Poway, cutting a new opening or enlarging an existing one puts you in front of the city’s structural requirements, and the shear wall has to be brought up to current code before the inspector signs off. We’ve handled enough of these to price the retrofit into the estimate from day one, not as a change order halfway through. That’s the difference between a General Contractor - Poway who knows the east side and one who’s just passing through.
CGI Models & Products We Service in Poway
Our crews work on the full range of CGI residential and commercial lines: CGI 950 Series impact windows, CGI Estate Collection windows, CGI 800 Series sliding glass doors, and CGI Commercial/Storefront aluminum frames. When a repair affects structural integrity or impact rating, we use OEM CGI parts, including laminated glass and multipoint locks. For worn rollers, weatherstripping, and balance springs, we often install quality aftermarket equivalents that stop drafts and ease operation at a lower cost. We’ll also tell you straight when a 30-year-old CGI unit with a failed thermal seal makes more sense to replace than repair. That honesty is part of how we handle CGI sales & service across the county.

FAQs – CGI Construction in Poway
You often will if the home is east of Espola Road and built before 1990. Poway’s building department has flagged undersized shear walls on many of those original homes, and pulling a permit for an enlarged opening typically triggers the upgrade requirement. We identify this risk before we quote so the estimate reflects the full scope, not a surprise add-on. Call (619) 673-9302 and we’ll check your specific home.
It depends on the unit. If the frame is sound and the fogging is from a failed thermal seal in the insulated glass unit, we can often replace the glass pack. If the frame is warped, the powder coat is gone, or the window is 25-plus years old, a full sash or frame replacement usually makes more financial sense. We’ll show you both numbers and let you decide.
Yes. Rollers and weatherstripping don’t affect the impact rating of your CGI door, so quality aftermarket equivalents are a smart, lower-cost fix. We use aftermarket parts for those wear items and reserve OEM parts for laminated glass, multipoint locks, and anything that affects structural or impact performance. You get a door that slides properly without paying factory markup on parts that don’t need it.
They can, yes. Poway’s inland valley sits hotter than the coast, and old single-pane or thermally failed windows let a lot of heat through. New CGI impact units with low-E coatings reduce solar heat gain, which means your AC doesn’t work as hard. The savings depend on your insulation, roof condition, and window orientation, so call (619) 673-9302 for an estimate and we’ll walk you through what actually applies to your home.
Check for drafts around the frame, feel for hot spots on the glass in the afternoon, and look for condensation or haze between the panes. If the window is hot to the touch while the roof insulation is decent, the windows are a likely culprit. We can run a quick assessment during a free estimate and tell you whether the windows, the roof, or both are driving the bill.
