Call (213) 221-0788 to schedule your free estimate.
Why Van Nuys Residents Choose Us for CGI Service
We’ve worked on CGI products in Van Nuys long enough to know the difference between a Series 400 aluminum slider in a 1970s tuck-under apartment and a Series 200 vinyl single-hung in a 1950s stucco ranch - experience that also informs our Van Nuys Kitchen Remodeling work. Grant Rowan studied construction technology at Los Angeles Valley College in Valley Glen before he ever ran a crew, and that discipline of reading the drawings first shows up in how we quote CGI work - every line item named, every part spec’d, every price written before anyone touches a tool.
Our CGI sales & service approach is straightforward: we source OEM-spec replacement parts when they’re available, but we’ll tell you honestly when aftermarket seals, rollers, or glazing outperform original components under Van Nuys conditions. The 365-Day Done Right Promise applies to every job, backed by The Haven Standard, not a handshake. Under Clause 1, the price is written before anyone starts. We’ve delivered 4,000-plus projects since 2007, and our crews are background-checked, uniformed, and arrive with a documented photo record as standard - not an upgrade.
Common CGI Construction Problems We Solve in Van Nuys
- Sealant failure at aluminum frame miters. CGI Series 400 windows in Van Nuys’ 1960s-70s tuck-under apartments expand and contract dramatically when summer temperatures exceed 100°F. That thermal cycling cracks the sealant at mitered corners, letting water intrude during the Valley’s occasional hard rains. We remove the failed sealant, prep the joint, and apply silicone rated for the temperature swing.
- Corroded galvanized steel rollers and tracks. Original CGI sliding hardware seizes after decades of heat cycling in the San Fernando Valley. The window that used to glide now grinds. We replace with stainless or polymer rollers that won’t corrode in the same conditions.
- Wood-clad delamination from stucco cracks. On 1950s Van Nuys ranch homes with deferred Northridge-era repairs, exterior stucco cracks let moisture behind the frame. CGI custom wood-clad units check or delaminate. We assess whether the cladding is salvageable or if water damage has reached the substrate.
- Condensation damage in storefront systems. CGI aluminum storefront and entry systems on older Van Nuys Boulevard commercial buildings often lack thermal breaks. The Valley’s hot-cold swings produce interior condensation that damages drywall and flooring. We evaluate whether retrofit glazing or full replacement with a thermally broken system makes sense.
- Glazing failures from seismic movement. The 1994 Northridge earthquake left micro-movements in Van Nuys framing that continue to stress CGI window glazing. We’ve re-glazed units where the original bedding compound cracked from ongoing settlement, not just the quake itself.

AfterCGI Service in Van Nuys: What Local Conditions Mean for Your Equipment
Van Nuys falls under Los Angeles Ordinance 183893, the mandatory soft-story retrofit law, which has put thousands of 1960s-70s tuck-under apartment buildings on a compliance clock. This drives a constant stream of seismic retrofit construction that routinely uncovers unpermitted rear additions, forcing legalization work that can double project scope before seismic strengthening even starts. For CGI product owners, this matters because the retrofit contractor is often the first person to open walls in thirty years - and that’s when we find the original CGI Series 400 windows were installed without proper flashing, or that a 1980s garage conversion used incompatible storefront systems that won’t meet current energy code. We were called to a 1960s tuck-under apartment on Van Nuys Boulevard where the owner needed soft-story retrofit work, and during the LADBS permit inspection, the inspector flagged an unpermitted rear garage conversion from the 1980s that had to be legalized. Our crew handled the retrofit and the legalization together, reinforcing the ground-floor parking area and bringing the converted unit up to current code, all while managing the compressed summer work hours due to CalOSHA heat protocols. The San Fernando Valley runs 10-15°F hotter than the LA coast, and those compressed hours are real - concrete pours and roofing work start earlier and finish earlier than on coastal job sites, which affects scheduling for any CGI installation tied to a larger envelope repair.
CGI Models & Products We Service in Van Nuys
We work with the full CGI residential and light commercial lineup: Series 400 Aluminum Sliding Windows, the workhorse of Van Nuys’ 1960s-70s apartment construction; Series 200 Vinyl Single-Hung Windows, common in post-WWII stucco ranch homes; Custom Wood-Clad Awning Windows; and Aluminum Storefront & Entry Systems for small commercial or mixed-use properties along Van Nuys Boulevard. Our Van Nuys service area stocking includes common CGI rollers, seals, and glazing components for faster turnaround on repair calls. When we quote replacement, we specify whether the new unit is thermally broken and what that means for your particular building’s exposure. Measure twice, write it down, then build it.

FAQs - CGI Construction in Van Nuys
Yes, if your building has open parking or commercial space at ground level and was built before 1978, it likely falls under Ordinance 183893. We handle the seismic retrofit, the permit process through the Van Nuys LADBS satellite office, and any unpermitted work that surfaces during inspection. Call (213) 221-0788 to schedule a structural evaluation - estimates are free.
Usually repairable if the frame extrusions are intact. Corroded rollers and failed sealant are fixable; bent frames or thermal-break failure means replacement is smarter long-term. We’ll inspect and tell you which side of the line your units fall on. Call (213) 221-0788 for an exact quote - estimates are free.
Yes, we pull all required permits and schedule inspections. Our field vignette experience with that Van Nuys Boulevard tuck-under taught us to anticipate what LADBS inspectors flag on older buildings, so we build that into the initial scope rather than discovering it mid-project - a practice we carry into every Van Nuys Bathroom Remodeling job.
CalOSHA heat illness prevention protocols compress outdoor working hours when Van Nuys exceeds 100°F, which is more frequent here than on coastal job sites. We schedule concrete pours and roofing early, plan CGI envelope work for cooler windows, and build the timeline honestly rather than promising speed we can’t deliver safely.
Yes, we can replace older non-thermally-broken CGI storefront systems with modern thermally broken aluminum or alternative materials that meet current Title 24 energy standards. We’ll specify the U-factor and solar heat gain coefficient in writing before you decide. Call (213) 221-0788 for an exact quote - estimates are free.
