CGI Construction in Van Nuys, CA | Mason Remodeling Co Los Angeles
We provide independent CGI window and door service across Van Nuys, from Sentinel Series impact windows to 9500 Series sliders. We are not authorized by CGI, and that’s the point: our crew cuts into Van Nuys ranchers weekly, so we know exactly how these frames fail on post-tension slabs, in hard water, and under Santa Ana winds in this specific neighborhood. No corporate script, no guessing. Call (213) 632-5711 for a free estimate.
Why Van Nuys Residents Choose Us for CGI Service
Most of Van Nuys’s housing stock was built between 1945 and 1965, and the CGI windows and patio doors on those homes are now hitting the age where seals, rollers, and frame flashing start to fail. We have spent years cutting into these one-story stucco ranchers and minimal traditional homes, so we know which failure patterns show up on Vanowen Street versus Victory Boulevard versus the flat lots north of Sherman Way. Isaac Pruett grew up in the San Fernando Valley and trained at Los Angeles Trade-Technical College before two decades of residential and light commercial work across Los Angeles County. That means when we tell you a CGI frame has racked from slab movement, we’re not guessing; we’ve seen the same crack pattern in a dozen houses on your block.
We are an independent service provider, not a CGI authorized dealer. That matters because we can tell you honestly when a replacement sash is worth the money and when a quality aftermarket roller will outlast the original. We use genuine CGI parts when preserving the original impact rating matters, and machine-matched stainless components when they don’t. Either way, you get a written price before any work starts, and a technician whose name and photo you’ll receive before they arrive.

Common CGI Construction Problems We Solve in Van Nuys
- Frame-to-wall flashing delamination: The original CGI flashing on 1950s stucco pulls away as the slab settles unevenly beneath it. Water wicks behind the aluminum cladding and rots the rough opening. You’ll see bubbling paint or a soft corner; we see a flashing detail that needs to be cut out and redone.
- Seized rollers on 9500 Series sliders: Van Nuys water is hard, and the minerals pit CGI’s stainless steel rollers over time. After winter rains, grit works into the track and the panels jump or drag. We clean the channel, replace the rollers with genuine CGI or matched aftermarket stainless, and reset the panel height so it glides square.
- Fogged impact glass from seal failure: August heat in Van Nuys is relentless, and older CGI impact units lose their edge seal. Condensation forms between the panes. Then a Santa Ana event pressurizes that air space and sometimes cracks the inner lite. We replace the sash or reglaze the unit, depending on frame condition.
- Cracked sill channels on fixed windows: On flat sandy-loam lots, post-tension cables under the slab relax, and the sill channel of a CGI fixed window cracks at the lower miter. That lets air in all summer and water in all winter. We pull the sash, square the rough opening, and replace the extrusion.
- Whistling Sentinel windows during Santa Anas: The weatherstripping compresses over time, and high winds find the gap. We replace the weatherseal, check the frame for racking, and reset the sash alignment so the wind stays outside where it belongs.
CGI Service in Van Nuys: What Local Conditions Mean for Your Equipment
North of Victory Boulevard in Van Nuys, the lots flatten out and the soil turns sandy loam. That’s where we see the most predictable CGI failure pattern in the entire Valley: fixed windows over post-tension slabs crack at the lower sill miter when those cables fail. The slab relaxes, the frame racks, and the miter opens. You won’t see this in Sherman Oaks or Encino, where the soil is denser and slabs move less. Here in Van Nuys, that single crack can shunt rainwater behind the 1950s sheathing and into the wall cavity every winter. We check for it on every CGI service call north of Victory, because once the miter opens wider than three-sixteenths of an inch, shimming won’t hold. The unit gets replaced, not patched. That’s the honest answer, and it’s the one most Van Nuys homeowners never get from a brochure or a brand rep.
CGI Models & Products We Service in Van Nuys
We work on the CGI Sentinel Series impact windows, the Estate Collection, the Commercial Series storefront and curtain wall, and the 9500 Series sliding glass doors. For Sentinel and 9500 units, we stock genuine CGI replacement sashes, rollers, and weatherstripping locally, so Van Nuys turnaround is quick. For older Estate Collection hardware that’s out of production, we machine-match quality aftermarket stainless components rather than forcing a homeowner into a full replacement. We also cover the broader CGI construction scope: impact window installation, roof replacement and installation, and full kitchen remodeling.

FAQs – CGI Construction in Van Nuys
The fog is a seal failure. Van Nuys summer heat expands the air space between the panes, and once the edge seal is compromised, moisture gets drawn in and condenses. Winter is cooler and drier, so the fog may disappear, but the seal is still failed. The fix is replacing the sash or the glass unit, not the whole frame. Call (213) 632-5711 for an exact quote; estimates are free.
In most Van Nuys homes, the rollers are the problem, not the door. Hard water minerals pit the original stainless rollers, and post-rain grit makes them seize. We replace the rollers, clean the track, and reset the panel height. A full door replacement is only needed if the frame itself has racked from slab movement. Call (213) 632-5711 and we’ll tell you which one you’re dealing with.
No. The whistle means the weatherstripping has compressed or the sash is slightly out of alignment. The wind finds the gap and sings through it. We replace the weatherseal and square the sash back to the frame. If the frame has racked from slab movement, we’ll tell you that too, because new weatherstripping won’t fix a twisted frame. Call (213) 632-5711 for a free estimate.
Both, depending on what the unit needs. For Estate Collection hardware that’s still available, we use genuine CGI parts. For out-of-production components, we machine-match quality aftermarket stainless rather than forcing a full replacement. We’ll show you exactly what we’re putting in and why before we order it.
Often, yes. The usual culprit is the flashing pulling away from the stucco as the slab settles. We cut out the old flashing, reflash the rough opening, and reseal the frame. But if the sill channel has cracked from slab movement north of Victory Boulevard, Van Nuys Bathroom Remodeling experience tells us the fix may be a new sill extrusion or a full unit. We’ll show you the evidence either way. Call (213) 632-5711 for a free estimate.
