If your CGI windows or doors need attention, call (904) 478-8983 and a live person picks up.

Coral Gables throws a unique set of problems at window and door hardware. The Historic Preservation Board demands period-correct profiles on contributing structures, while Miami Cgi service providers know Miami-Dade’s High-Velocity Hurricane Zone code requires every replacement unit to carry an NOA rating. That dual pressure means CGI owners in this city need a service team that understands both the engineering and the aesthetic constraints. We do.

Why Trust Winslow Windows & Doors for Your CGI Windows & Doors?

Our technicians work on CGI products in Coral Gables constantly, so they know the hardware quirks that generic window companies miss. The Sentinel Impact Series, Estate Collection, Classic Aluminum Line, and 9500 Vinyl Series all have different frame geometries, balance systems, and weatherstripping profiles. A tech who only works on one brand will fumble through a CGI repair. Ours don’t.

Ed grew up in Coconut Grove near CGI Windows & Doors in Little Gables, FL, studied building construction technology at Miami Dade College, and spent his whole working life in South Florida’s sun, salt air, and hurricane seasons. That background matters when you’re diagnosing a CGI frame that’s been pitted by sprinkler overspray or a roller assembly jammed with sandy grit. We use OEM CGI parts when they’re available for current production lines, and proven aftermarket components when we’re working on discontinued models. Every repair is done with the warranty in mind. We never void a CGI warranty by substituting cheap hardware or skipping a required step. Ed’s name is on the truck, and that means we’re accountable for every job we touch in Coral Gables.

Common CGI Windows & Doors Problems We Fix in Coral Gables

• Sentinel Impact Series fogging between panes. The original glazing tape on CGI Sentinels dries out under relentless south-facing Coral Gables sun, letting humid air creep between the glass lites. Once moisture gets in, you get that milky fog that never clears. We deglaze, replace the failed tape with a marine-grade equivalent, and reseal the unit. If the glass itself is compromised, we source an OEM-compatible insulated unit rather than patching it.
• Horizontal slider rollers binding after storms. Coral Gables landscaping is heavy on sandy soil, and after a storm that grit blows into the bottom track of CGI horizontal sliders. The roller assemblies grind against it until they seize. We pull the panel, clean the track, and replace the rollers with OEM or matched aftermarket parts. The door or window slides like new, and we leave you with a maintenance note for keeping the track clear.
• Casement weep hole covers clogging with salt spray. CGI casement frames have small weep hole covers along the bottom rail that drain condensation. Salt air off Biscayne Bay combines with Coral Gables humidity and clogs those covers with a chalky residue. Water backs up, sits against the interior sill, and starts rotting soft wood in older homes. We clear the weep system, replace any corroded covers, and re-caulk the sill if needed.
• Classic Aluminum frame corners pitting from sprinkler overspray. Older CGI aluminum frames, especially on 1990s installations, develop pitting at the corners where irrigation water hits them night after night. The aluminum oxidizes, the corner joints weaken, and eventually the frame loses its seal. We sand, treat, and reseal minor pitting. When the corrosion has eaten through the corner, we tell you straight that a replacement is the smarter spend.
• Estate Collection spiral balance failures. The Estate double hung windows use spiral balances that eventually fatigue, particularly on the south and west sides of Coral Gables homes where sun exposure is highest. When they snap, the sash won’t stay up. We replace both balances on the affected window so it operates evenly, then re-caulk the exterior fins to keep moisture out of the frame channel.

CGI Parts & Our Repair-vs-Replace Approach

We source genuine OEM CGI parts for current production lines like the Sentinel Impact Series and 9500 Vinyl Series. For discontinued Classic Aluminum models, we use proven aftermarket balances, weatherstripping, and roller assemblies that match the original profile. That keeps older CGI windows serviceable without waiting weeks for a part that’s no longer made.

Here’s how we decide repair versus replace, and it’s simple. If the CGI frame is structurally sound, we repair it. A roller assembly, balance, or seal failure is a part problem, not a frame problem. If the sill or jamb is compromised, whether from corrosion on an old aluminum frame or rot creeping up a wood surround, we tell you straight that Window Installation services cost less than chasing rust. We don’t pad jobs with unnecessary replacements, and we don’t patch frames that should be retired. When you call (904) 478-8983, you get an honest assessment, not a sales pitch.

Our CGI Service Process - Step by Step

1. 1
   Diagnosis. We inspect the CGI unit in place, identify the exact failure, and test the surrounding frame, track, and weatherstripping. For sliding doors we check the track alignment and roller condition. For casements we check the hinge, operator, and weep system. You get a written line-item quote before any work starts.
2. 2
   Repair or install. We use OEM CGI parts when available, matched aftermarket parts for discontinued lines, and we replace only what’s failed. If it’s a full frame replacement, we match the existing opening, including arched or radius profiles where Coral Gables historic standards apply.
3. 3
   Test. We cycle the window or door repeatedly, check for smooth travel, proper seal compression, and clean drainage. A CGI unit that passes our test runs quiet and holds its position.
4. 4
   Warranty and follow-up. Every job falls under the Done Right Promise. If anything’s off after we leave, we come back and make it right. That’s not a promotional line. It’s how we’ve done business in Coral Gables for over 15 years.

CGI Products We Service & Install in Coral Gables

Along with Impact Windows services, we service and install the full range of CGI product lines you’ll find in Coral Gables homes: the Sentinel Impact Series, Estate Collection, Classic Aluminum Line, and 9500 Vinyl Series. That covers horizontal sliding impact windows, double hung and casement impact windows, full frame replacements, and hurricane impact doors. We stock common CGI rollers, balances, weatherstripping, and weep covers locally so most repairs don’t wait on a distributor order. For custom fabricated units, such as arched impact windows for historic Coral Gables contribting structures, we work with fabricators who can match the original radius and keep the HPB happy.

We Also Service These Brands

CGI isn’t the only manufacturer we know inside and out. We service and install PGT, CWS, ES Windows, and ECO Window Systems as well. That multi-brand experience helps when a Coral Gables home has mixed window lines, which happens more often than you’d think after decades of additions and renovations. We’re not tied to one brand, so our recommendation is based on what’s right for your home.

FAQs - CGI Windows & Doors Service in Coral Gables

My CGI Sentinel windows are hard to slide after a storm. Is that normal?
It’s common in Coral Gables after heavy rain and wind because sandy grit gets blown into the bottom track and grinds against the roller assemblies. It’s not something to ignore, because continued force will flatten the rollers and damage the track. We clean the track, inspect the rollers, and replace worn sets. Call (904) 478-8983 if your Sentinels don’t glide easily.

Can you match the original CGI bronze finish on my 1990s aluminum frames?
Yes, for most Classic Aluminum Line frames we can match the bronze finish on replacement hardware, corner keys, and weatherstripping. Exact color matching on a 30-year-old frame requires careful selection because the original anodizing has faded unevenly in the Coral Gables sun. We bring samples and match on site.

Why does my CGI casement window weep water onto the sill only in the summer?
In Coral Gables, summer humidity combines with air conditioning running cold inside to create heavy condensation on the interior frame. If water is weeping onto the sill, the weep hole covers are likely clogged with salt residue and the drainage channel is blocked. We clear the weeps, replace any corroded covers, and the problem stops. If it persists, we’ll check the glazing seal for a hidden failure.

Should I repair or replace a CGI Estate window with foggy glass?
If the frame is sound and the only problem is fogging between panes, you can often replace the insulated glass unit without replacing the whole window. On Estate Collection windows we deglaze, replace the failed glazing components, and reseal the unit. But if the frame shows corrosion or the sash is warped, a full replacement is usually cheaper long-term. Call (904) 478-8983 for an exact assessment.

Do you stock CGI parts locally or do you have to order them?
We stock common CGI parts locally: roller assemblies, spiral balances, weep covers, and weatherstripping for the Sentinel, Estate, and 9500 lines. Less common or custom parts, like a specific glass unit for an arched opening, may take a few days from our fabricator partners. We’ll tell you the timeline before you approve any work.

Is Winslow Windows & Doors authorized by CGI?
No. We are an independent CGI service provider, not a manufacturer-authorized dealer. That means we’re free to recommend exactly what’s best for your home, whether it’s an OEM part, a proven aftermarket component for a discontinued line, or an honest replacement recommendation. Our independence is an advantage, not a limitation.
