Why Orange County Homeowners Choose CGI Construction
Bradford Remodeling Co Orange County provides CGI Construction in Orange County, CA as an independent service, handling impact window installations, replacements, and repairs on Sentinel Series, Estate Collection, and Targa Series products. We are not affiliated with or authorized by CGI, which means we answer to one party only: the homeowner writing the check. If you need a straight diagnosis on a CGI product, call (562) 262-2907.
Here is the difference. Most contractors in Orange County treat CGI products like any other window. They are not. CGI builds impact-rated systems engineered to hold frame and glass under hurricane-force wind loads. A sloppy install does not just leak. It voids the product’s structural rating. Our crews understand the load paths, the anchoring schedules, and the sealant chemistry these systems require. We have pulled countless failed Cgi service in Mission Viejo and other area installs apart in Newport Beach, Huntington Beach, and Seal Beach where the problem was never the product. It was the previous contractor’s work.
Why Trust Bradford Remodeling Co Orange County for Your CGI Construction?

Curtis Lane grew up in East Los Angeles and learned residential framing, finish carpentry, and plan reading at Los Angeles Trade-Technical College. He has been running crews across Orange County for well over a decade, from Anaheim Hills track homes to full gut-and-rebuild projects near Balboa Island. That background matters when you are dealing with CGI products because impact-rated windows and doors are unforgiving. The rough opening has to be square, the anchoring has to be precise, and the flashing has to be layered correctly or water finds a way in.
Our technicians work with CGI products on a near-daily basis. We know the Sentinel Series failure modes, the Targa Series track wear patterns, and the corrosion issues that show up on Estate Collection frames in beach-adjacent neighborhoods. We use OEM CGI gaskets, rollers, and hardware for structural or weather-seal repairs because the tolerances are tight and a mismatched part voids the impact rating. Where a cosmetic item like interior trim or a screen can be swapped for a quality aftermarket equivalent without compromising performance, we tell you that and let you choose. Straight number, clear scope, no surprises at final invoice.
Every project we complete carries the 365-Day Done Right Promise in writing. If the work fails inside that year, we return and correct it at no charge. That guarantee sits on top of the manufacturer’s own warranty, not in place of it.

Common CGI Construction Problems We Fix in Orange County
- Thermal seal failure and fogging between panes on Sentinel Series windows: We see this most often on west-facing exposures in inland Orange County cities like Yorba Linda and Anaheim Hills, where afternoon sun pounds the glass for hours. The seal breaks down over time, moisture gets between the panes, and the window clouds. The fix is replacing the insulated glass unit or the sash, not the whole frame, assuming the frame is still sound.
- Corrosion and pitting of aluminum frames on beach-adjacent homes: Salt air in Corona del Mar, Laguna Beach, and Huntington Harbour attacks the aluminum frame finish if it is not rinsed regularly. Our crew recently replaced a pair of corroded CGI Estate Series windows on a Corona del Mar home. We sourced OEM replacement sashes with matching bronze frames, replaced the degraded perimeter sealant, and reinstalled to factory spec so the owner could keep their coastal insurance discount.
- Roller and track wear on sliding Targa Series doors: Sand and debris work into the tracks over the years, and the rollers wear flat. The door starts sticking, then misaligns, then the lock stops lining up. We replace the rollers and guides with OEM CGI parts, clean the track bed, and realign the panel. That is usually a same-visit fix.
- Leaks around flanges and sills from improper installation: This is the one that gets blamed on the product. In most leak cases we inspect, the failure is at the perimeter sealant or the flashing detail, not the CGI window itself. Some previous contractor skipped a step. We pull the trim, inspect the rough opening, correct the flashing, and reseal to manufacturer spec.
- Fogged glass and failed impact glazing after attempted DIY repairs: An impact window is not a standard pane. The laminated glass and the interlayer are part of the system’s rating. When someone replaces a pane with the wrong glass, the window loses its certification and the homeowner may not find out until an insurance review. We see this often enough in Garden Grove and Westminster to flag it.
CGI Parts & Our Repair-vs-Replace Approach

We prefer OEM CGI gaskets, rollers, hinges, and hardware for any structural or weather-seal repair. The impact rating of a Sentinel or Targa product depends on every component working as an engineered system. A generic roller with a slightly different diameter changes the door’s geometry. A cheaper gasket with the wrong durometer doesn’t compress the same way. The window still looks fine until a storm or a water test says otherwise.
Repair is the right call when the frame is intact, the glass is clear, and the failure is isolated to a wearable part. Replacement makes sense when the frame is corroded through, the interlayer is visibly delaminating, or the cost of repairs exceeds roughly half the cost of a new unit. We give you the numbers for both paths and make a recommendation. The decision stays yours.
We stock common CGI hardware locally for fast turnaround on rollers, keepers, and gaskets. Custom color-matched sashes and large-format glass run through the manufacturer and take longer. We tell you the timeline upfront. Call (562) 262-2907 for an exact quote. Estimates are free.
Our CGI Service Process – Step by Step
- 1
Diagnosis: We inspect the product, the rough opening, and the surrounding wall assembly. We are looking for seal failure, frame deflection, anchoring issues, and water intrusion paths. You get a written diagnosis with the price before any work begins.
- 2
Sourcing: We order OEM CGI parts or full units with the correct frame color, glass package, and impact rating for your exposure and zone. No substitutions without your written approval.
- 3
Repair or installation: We pull the old unit, correct any framing or flashing deficiencies, set the new product to factory spec, and seal with materials rated for your location. Coastal jobs get marine-grade sealants. Inland jobs get UV-stable products.
- 4
Testing and closeout: We run a water test on exterior work, cycle every operable panel, and confirm locking hardware functions. The site is clean, the scope is documented, and you get the signed written guarantee in your hand before we leave.

FAQs – CGI Construction Service in Orange County
It depends on where the seal failed and whether the sash frame is still structurally sound. In many cases, the insulated glass unit can be replaced independently. If the frame is corroded or the interlayer is delaminating, a full replacement sash is the safer repair because the impact rating stays intact. We will show you both options and the price for each. Call (562) 262-2907 and we will inspect it.
Most hard-to-operate Targa doors in need of Cgi repair in Santa Ana and surrounding areas have worn rollers or debris built up in the track. We replace the rollers and guides with OEM CGI parts, clean and align the track, and check the panel for sag. If the slab has dropped out of square, we adjust the hinge or roller assemblies back to factory spec. It is typically a same-visit repair. Call (562) 262-2907 to schedule a service call.
Not necessarily. Most leaks around CGI frames trace back to failed perimeter sealant or a flashing error at the rough opening, not a product defect. We pull the interior and exterior trim, inspect the installation, correct the flashing if needed, and reseal with the right product for your exposure. A full re-install is only warranted when the frame itself is compromised. The diagnosis tells you which path applies.
Yes. Homes within about a mile of the coast in Newport Beach, Laguna Beach, Huntington Beach, and Seal Beach get salt-laden air that attacks aluminum frame finishes. CGI products have protective finishes, but the finish still needs periodic rinsing with fresh water to remove salt deposits. We see corrosion accelerate when homeowners never rinse the frames. If the pitting has started, we can often source replacement sashes in the matching finish before the frame itself needs replacing.
Yes. For room additions and bump-outs, we install CGI products as part of the rough-in phase before drywall and trim go up. This is the cleanest way to add impact-rated windows to new square footage. For existing walls where you are replacing windows, the old units come out and the new CGI units go into the same openings after we verify the framing and flashing. The process is invasive only to the extent required to do the job correctly.
