CGI Windows & Doors: The San Diego Owner’s Guide
We stock and install CGI-compatible windows and doors throughout San Diego, with most replacements running $944 – $2,950 for parts and a typical installed window replacement landing between $5,310 – $17,700 depending on opening size and series. The call usually starts the same way: a crank handle that spins without moving the sash, a lock that won’t engage, or a sliding door that’s started grinding against its track. You call when the part’s failed, not when it’s thinking about failing. We get that. Tell me what’s broken. I’ll tell you what it takes.
CGI builds impact-rated windows and doors, and the hardware carries heavier loads than standard residential units. That’s the whole point of the product. But salt air, coastal humidity, and the fine grit that blows through a San Diego dry season all work against rollers, balances, seals, and locks long before the glass ever gives up. If you’re in Point Loma, Coronado, or anywhere within a few blocks of the coast, expect hardware wear faster than inland neighborhoods like Rancho Bernardo or Scripps Ranch. The aluminum frames hold up. The moving parts need attention first.
Which CGI Models This Applies To

Our parts inventory covers the most common CGI product lines installed across San Diego County, including the Sentinel series casement and fixed windows, Estate collection single hungs and sliders, and the Tapestry line of hinged and sliding patio doors. Before you order anything, locate the sticker. CGI etches or labels a product identification code into the frame corner or the edge of the sash on nearly every unit. That code tells us the series, glass package, and the specific hardware spec your window was built with. If the label’s gone, we measure the sash thickness and hinge spacing, which narrows it down to the right generation.
Here’s the compatibility gotcha most owners run into: CGI changed roller housing dimensions on sliding doors around 2016, and the newer stainless steel rollers will not seat correctly in the older extruded track profiles. You can’t just eyeball it from a photo. We’ve seen homeowners buy a “universal” replacement online and spend two weekends trying to get it seated before calling us. For CGI specifically, OEM hardware is worth the premium on load-bearing components like impact-rated hinges and multi-point lock sets. Aftermarket equivalents are fine for cosmetic trim, weatherstripping, and handle sets where the tolerances aren’t structural. We’ll tell you which is which without upselling.

Signs Your CGI Windows & Doors Is Failing
- Crank handle spins freely or clicks without moving the sash. The operator gear teeth have stripped, common on casement windows in coastal San Diego where salt corrosion accelerates wear. Replacement is a matched CGI operator, not a universal part.
- Sliding door grinds or drags when opening. The rollers have flat-spotted or seized, usually on the heavy impact-rated panels. You’ll hear grit in the track and feel the panel fight you. Continuing to force it bends the track and turns a $300 roller job into a full panel replacement.
- Lock won’t throw or binds halfway. Multi-point locks on CGI French and patio doors depend on precise alignment between the door panel and frame. Foundation settling, which shows up in older San Diego homes from Normal Heights to Clairemont, knocks that alignment out slowly until the lock simply won’t engage.
- Window won’t stay up or drops when released. The balance system has failed. On impact-rated single hungs, the heavier sash glass means a failed balance turns a one-hand operation into a two-hand fight, and it’s a pinched-finger risk for kids.
- Condensation between the glass panes or a visible haze that won’t wipe off. The seal has failed and the insulating gas has escaped. The window still functions structurally, but you’re losing energy performance and the fog never improves on its own.
Replacement Cost & What’s Included

For CGI hardware replacement on an existing window or door, San Diego homeowners typically pay $944 – $2,950 for the part and labor together. That covers rollers, operators, balance systems, lock sets, weatherstripping, and manual handle assemblies. Full window replacement runs $5,310 – $17,700 installed, and impact-rated door swaps climb into the $9,440 – $29,500 range when the frame itself needs to come out. What drives the number is the series compatibility, whether the original frame is salvageable, and how much disassembly the install requires.
Every estimate we write in San Diego is a written line-item price before any work starts. You’ll see the part number, the labor, and the total. Nothing appears on the final bill that wasn’t on the first sheet. Our workmanship carries a 365-day guarantee from the completion date. If a part we installed fails within that year, we return and make it right at no charge. No dispute process. No conditions.

You can safely check a few things yourself: clean the track, confirm the screws on the handle set are snug, and take clear photos of the label and the failed hardware before calling. That photograph saves a trip and helps us bring the right part the first time. What you shouldn’t do is start removing impact-rated hardware without knowing the panel weight. A CGI sliding door panel can run 200 pounds or more. One wrong move with a pry bar and you’ve got a broken glass package that costs more than the original repair.
If the part in question is a balance system under tension or anything structural, let us handle it. Trained professionals deal with high-tension components every day, and we carry the right tools and matched CGI specs on the truck. Call (619) 673-9302 and we’ll tell you over the phone whether it’s a parts-only visit or a full replacement. No charge for the conversation.
FAQs

CGI frames and impact glass typically last 20 – 30 years in San Diego’s climate, but the hardware (rollers, balances, locks, and seals) generally needs replacement every 8 – 12 years, sooner for homes within a mile of the coast where salt air accelerates corrosion. Glass rarely fails without impact. The moving parts go first.
Seals and weatherstripping can often be replaced or re-glued by a homeowner comfortable with basic tools, but stripped operators, seized rollers, and failed balances are replacement-only items on CGI products. Attempting to rebuild a sealed operator housing usually costs more in time than a matched replacement part. Call (619) 673-9302 and describe what’s failing. We’ll give you a straight answer.
Most single-part replacements like a roller swap, balance replacement, or lock set install take 45 – 90 minutes on site once we have the correct CGI spec confirmed. Sliding door panel removal for roller replacement adds time. Full window or door replacement typically runs one day for standard openings.
We stock the most commonly replaced CGI hardware on our trucks, including Sentry series rollers, Sentinel operators, and Estate series lock sets. Less common parts are ordered by model code and arrive at our San Diego shop within a few business days. We also carry parts for KraftMaid cabinetry and Cambria and Silestone surfaces when a window or door issue sits near other millwork.
