AfterCGI Construction in Los Angeles, CA | Rowan Construction Group
We provide independent CGI window and door service across Los Angeles, from impact-rated replacements to frame realignment on retrofit jobs. The thing that makes our CGI work here different is the soft-story retrofit ordinance, Ordinance 183893, which forces thousands of pre-1980 buildings into seismic upgrades that directly conflict with existing CGI rough openings. We reframe those openings, reset the units, and keep the shear wall intact. Call (470) 298-9650 for a written price before any work starts.
Rowan Construction Group has been quoting flat written prices since 2007. Every CGI job we take in Los Angeles gets a documented photo record on the first visit and a written scope before a single fastener comes out. We’re not a CGI factory shop. We’re an independent Los Angeles contractor that knows the product lines well enough to repair them honestly, and we’ll tell you when a replacement is actually necessary rather than selling one by default.
Why Los Angeles Residents Choose Us for CGI Service
Our crews have opened up hundreds of CGI window and door installations across Los Angeles, from hillside homes in Pacific Palisades to stucco tract houses throughout the San Fernando Valley. We know how CGI’s impact-resistant lines behave under coastal corrosion, seismic racking, and WUI fire exposure. That’s not manufacturer training. That’s field time.
Grant Rowan grew up in the Crenshaw district and trained in construction technology at Los Angeles Trade-Technical College, where framing, concrete, and our Driveway & Pavers in Los Angeles estimating came before any paying job. Two decades of residential work across Los Angeles County later, the calls he gets most often are structural remodels, the ones where load paths change and window openings move. That’s exactly what CGI work in this city usually is. We’re independent, so we diagnose and repair CGI products without the pressure to sell a replacement just because a factory authorization would require it. Measure twice, say it once, show your work.
Common CGI Construction Problems We Solve in Los Angeles
- Worn sill track gaskets on CGI Estate sliders. Los Angeles dry-season dust plus Santa Ana wind grit works under the gaskets, the panel starts to drag, rollers wear unevenly, and the lock stile drops. We replace the gaskets and rollers, then realign the panel so it runs clean.
- Rack-induced frame deformation on pre-1980 buildings. When a soft-story retrofit adds shear walls next to existing window openings, CGI frames pick up twist and reveal gaps that fail the 1/8-inch alignment check. We reframe and reset the unit.
- Salt-air pitting on CGI Sentinel fixed-lites. From Venice to San Pedro, the aluminum cladding survives coastal air fine, but the stainless hardware seizes and glass retention clips start to shear. We swap hardware and clips before glass comes loose.
- Failed butyl tape seals at window-to-wall intersections. Valley stucco homes on expansive clay see real seasonal movement. Dry summer shrinks the soil, winter rain heaves it, and the racking breaks the original perimeter seal. Water gets in. We pull the trim, replace the seal, and flash the opening properly.
- Seized sashes after retrofit work. New shear panels next to existing openings twist frames out of square, and sashes lock shut. We release them, realign the frame, and install new balance springs and side jamb gaskets so the window operates one-handed.
BeforeAfterCGI Service in Los Angeles: What Local Conditions Mean for Your Equipment
Los Angeles is the only major U.S. city where a mandatory soft-story retrofit ordinance, Ordinance 183893, puts thousands of pre-1980 wood-frame apartment buildings over open parking into seismic upgrade scopes that directly conflict with existing CGI window rough openings. A building on Cochran Avenue in Mid-City, a 1964 dingbat, had three CGI Estate single-hung windows seize shut after an LADBS-mandated retrofit added a plywood shear panel next to each opening. The frames twisted out of square. Our crew spent two days there. We pulled the sashes, realigned the frames with epoxy-set anchor straps to the new shear wall, and reinstalled the original sashes with new CGI balance springs and side jamb gaskets. The windows now operate with one hand and pass the WUI seal inspection. That is not a problem you’ll see in Pasadena or Long Beach at the same frequency. That specific conflict, shear wall against existing CGI opening, is Los Angeles work.
CGI Models & Products We Service in Los Angeles
We service the CGI Estate Collection, the Estate Impact Series, the Sentinel Series for hurricane-rated openings, and the Classic Series non-impact aluminum line. Our parts shelf carries CGI-specific rollers, lock stiles, corner gaskets, and balance springs for faster turnaround across Los Angeles. We use OEM parts whenever the original component is still available and the client wants a factory fit. For discontinued CGI lines where lead times run past a closing date, we source high-grade aftermarket equivalents from manufacturers we’ve vetted over years of repeat use. We always tell the client which route we’re taking and why.
CGI Service Pricing in Los Angeles
Every CGI job starts with a written flat price before work begins. The quote covers the scope, the materials, and the warranty in writing, and no change proceeds without a signed change order. That’s been Rowan’s discipline since 2007, and it’s the reason our projects finish within a few percent of the agreed number.
| Service | Price Range |
|---|---|
| Impact Window Installation | $9,440 - $29,500 |
| Window Replacement | $5,310 - $17,700 |
| Roof Repair | $470 - $2,125 |
What drives cost in Los Angeles specifically is the permit path. LADBS plan check backlogs can add three to five months to a project that isn’t structured for over-the-counter review. We plan scopes to keep simple CGI replacements in the over-the-counter queue whenever possible. Call (470) 298-9650 for a written estimate, and you’ll have a number in dollars before anyone picks up a tool.

FAQs - CGI Construction in Los Angeles
If your building is pre-1980, wood-frame, and has open parking on the ground level, the retrofit adds shear walls near existing openings. Your CGI frames can twist out of square and seize. We realign the frame against the new shear wall, anchor it properly, and keep the window or door functional. Call (470) 298-9650 for an exact scope, and ask about our free second opinion on any written estimate you’ve received.
Not unless you’re within a few blocks of the coast. In most of Los Angeles, including the Valley, it’s dry-season dust and Santa Ana grit packed into the sill track gaskets. We replace the gaskets and rollers, realign the panel, and it runs clean. If you’re in Venice or San Pedro, salt pitting on hardware is the more likely culprit. Call (470) 298-9650 and we’ll diagnose it on site.
Yes, often. If the frame is square, the glass is intact, and the hardware is serviceable, a repair with OEM or equivalent parts gets years more out of the unit. We’ll tell you when corrosion, racking, or glass damage makes a replacement smarter than a patch. We’re independent, so the answer isn’t predetermined. Call (470) 298-9650 for a written repair quote.
Yes, with the right detailing. Hillside communities in the Santa Monica Mountains and Verdugo Hills fall under LADBS Wildland-Urban Interface fire zone requirements, which mandate ember-resistant vents and one-hour fire-rated exterior assemblies. CGI impact units can meet WUI seal inspection standards when installed with the correct flashing and perimeter seal. We’ve passed those inspections. Call (470) 298-9650 and we’ll write the scope to your zone requirements.
We can match the frame profile, glass type, and finish on most CGI lines still in production, and we’ll source a visually consistent equivalent for discontinued series. The written quote includes the exact product specs, so you know what you’re getting before work starts. Call (470) 298-9650 for a free estimate on matching your existing CGI units.
