CGI Impact Windows in Miami: What to Know First
We install, service, and replace CGI impact windows throughout Miami as an independent CGI service provider. Most repairs take one visit, and most full replacements run two to three days once your windows arrive. You’ll get a written line-item quote before any work begins, not a ballpark and a shrug.
This page is for Miami homeowners who already have CGI windows, are considering them, or inherited them with a house purchase. If you’re researching whether CGI is worth the money in our salt air and hurricane wind zone, or you’ve got a window that won’t slide, a cracked laminate panel, or condensation between the glass, you’re in the right place. Call (863) 862-5435 and a live person answers, any hour.
How CGI Products Fail - and How We Fix Them
CGI makes a serious impact window. But Miami tests every product harder than any lab, and after 15 years of pulling these windows apart, we know exactly where they show their age. Here’s what we actually see in the field:
- Sentinela Series slider rollers and track wear. The Sentinela 8800 is a common sight in older Miami homes, and its sliding panels ride on nylon rollers that grind down after years of salt and sand. The window binds, then jams, then someone yanks it and bends the frame. We replace the rollers with the correct weight-rated match and realign the track, which is a Saturday-afternoon fix for us, not a window replacement.
- Targa Series weep hole blockages from salt crust. Targa single-hung and picture windows drain through weep holes at the bottom track. Miami’s salt air forms a crust inside those channels that traps water against the frame. The symptom is water pooling on the interior sill after rain, which looks like a seal failure but is usually just clogged drainage. We clear the channels, flush the track, and show you how to keep them clear between storms.
- Estate Collection laminated glass seal fatigue. CGI’s Estate line uses a laminated interlayer for impact resistance. After a decade of Miami sun, the butyl seal around the glass can lose elasticity, and you get fogging or a filmy haze between the panes. The outer glass is fine, but the insulating unit has failed. We replace the glass pack with an impact-rated unit that matches the original CGI frame, so you keep your warranty profile and don’t pay for a whole new window.
- Hinged casement friction stays wearing on CGI casement windows. CGI casements open on stainless steel friction hinges that eventually loosen, so the sash drops when you open it. On a windy Miami afternoon that’s a finger hazard and a stress crack waiting to happen. We replace the hinges and recalibrate the opening limit, and the window operates like new.
- Frame gasket compression set in CGI fixed and picture windows. The rubber gaskets that seal the glass into the frame compress over time and lose their rebound, especially on south-facing walls. You start feeling warm air near the window edges and hear wind whistle during storms. We re-glaze with a fresh gasket that matches the original CGI profile, which restores the air seal and quiets the house back down.
Our CGI Impact Windows Process
Every CGI job we do in Miami follows the same path. No shortcuts, no surprises:
- 1
You call (863) 862-5435. A live person answers and listens to what’s happening with your window. We ask questions, not put you on hold.
- 2
We diagnose on site. A background-checked, uniformed technician comes out and looks at the actual window, the frame, the track, the glazing, and the wall opening. We tell you what’s wrong at the window, not over the phone.
- 3
Parts decision. For warrantied CGI windows, we use OEM parts so you don’t void anything. For older out-of-warranty windows, we match with quality aftermarket parts when they match the spec, always telling you which way we’re going and why.
- 4
The repair or replacement. We do the work, clean the opening, reset the window, and flash it exactly the way Miami’s coastal building code requires.
- 5
We test it. We check the operation, the seal, and the drainage before we pack up. If water can get in, we find out before the next storm does.
- 6
You get our word. Every job falls under the 36500-Day Done Right Promise. If it’s not done right, we come back and make it right. Period.
What CGI Impact Windows Costs in Miami
CGI repair and replacement costs in Miami depend on what’s actually wrong, not on what we can upsell. Here are realistic ranges for common CGI work:
| CGI Job | Typical Miami Cost |
|---|---|
| Slider roller replacement (Sentinela, per panel) | $140 - $260 |
| Weep hole clearing and track flush (per window) | $90 - $180 |
| Insulated glass replacement (Estate/Targa, per unit) | $380 - $750 |
| Friction hinge replacement (casement, per sash) | $160 - $310 |
| Full CGI window replacement (installed, per opening) | $1,100 - $2,800+ depending on size and series |
What moves the price: window size, whether it’s a second-story install, the series you own, whether we’re matching an existing glass tint or laminate spec, and whether the frame itself is still sound. We show you the number on paper before we touch a single screw. Call (863) 862-5435 for a free estimate and a straight answer about what your CGI window actually needs.
Why Miami Homeowners Call Winslow Windows & Doors for CGI Work
Because we answer the phone. Because Ed Winslow grew up in Kendall, went through the construction technology program at Miami Dade College, and spent years working alongside seasoned installers across South Florida before putting his own name on a truck. My name is on the door - literally. When a CGI window fails in this city, you want the person responsible for fixing it to be findable, accountable, and reachable at 2 a.m. We’re all three.
We’re authorized installers for CGI, PGT, CWS, ES Windows, ECO Window Systems, and others, so if a repair says replace it instead, we can show you comparable options across brands without dragging you to a showroom. We’ve been serving Miami since 2011, locally owned and owner-operated, with a published address and license number. That’s the one down the road.
FAQs
No, as long as the work is done correctly and with the right parts. For warrantied windows, we use OEM CGI components and follow the manufacturer’s installation standards. For out-of-warranty windows, we still match specifications so the window performs the way it was designed to. Call (863) 862-5435 and we’ll tell you honestly which parts your window needs and whether warranty coverage applies.
In most cases, yes. CGI’s glass packages are specific: low-E, gray or bronze tint, laminated interlayers, and Miami-Dade NOA numbers. We match the new glass pack to your frame and your existing windows so nothing looks mismatched. Bring us the NOA sticker photo if you have it; it speeds everything up.
Most slider roller and hinge replacements take under two hours per window. Glass pack replacements usually take one week because we order the insulated unit to spec. Full window replacements take two to three days once product arrives, depending on how many openings we’re doing. We’ll give you a written timeline at the estimate.
If the frame is square, the glass is intact, and the failure is a roller, hinge, gasket, or weep issue, repair is almost always the smarter money. We won’t sell you a new window when a $200 fix does the job. Call (863) 862-5435 for a free estimate and we’ll tell you straight which path makes sense for your home.
Yes. Full window replacement in Miami triggers permit and inspection requirements under the Florida Building Code, and we handle that on every job. Permits get pulled, inspections get passed, and every install meets Miami-Dade’s impact standards. A window that isn’t permitted and inspected isn’t really protecting your house, and we won’t leave you in that position.
