CGI Sliding Glass & Patio Doors in Miami: What to Know First
We repair and replace CGI sliding glass and patio doors across Miami as an independent CGI service provider, which means we work on the door, not for the manufacturer. Most CGI slider repairs in the Miami area take one visit, and we quote line-item prices before we touch a screwdriver. If you have a CGI patio door that’s dragging, leaking, or locking up, call (844) 901-4551 for a free estimate, and you’ll get Ed Winslow’s team, not a ticket number.
This page is for homeowners in Miami who already have CGI sliding glass or patio doors and need straight answers about fixing them, or who are exploring replacement doors and want to know how CGI compares in a coastal climate. We service the brand daily, from older Estate and Targa units to current M-Series and Classic sliders. The short version: CGI builds a strong door, but Miami’s salt air, afternoon downpours, and UV load find the weak points fast, and we know exactly where to look.

- Our Done Right Promise applies to every CGI door we fix or install.

How CGI Products Fail — and How We Fix Them
CGI doors hold up better than most in a hurricane zone, but Miami’s heat and humidity still find every weak point. Here’s what we see most often on CGI sliders and patio doors, by series where it matters.
- Targa and Estate series roller failures at the bottom track. These older CGI sliders run on steel ball-bearing rollers that were perfectly fine for inland Florida but corrode fast near Biscayne Bay and the coast. The symptom is a door that starts gliding rough, then needs a hip-check to move. The fix is not just replacing the roller; we also clean and reseal the track channel so the new rollers don’t sit in a salt-filled gutter.
- M-Series and Classic slider interlock wear causing air and water bypass. The interlock is where the two panels meet, and on CGI sliders it’s a vinyl gasket that compresses with age. We see this all the time in Miami communities like Kendall and Shenandoah. Homeowners notice the door whistles on windy days or leaves a damp line on the tile after a heavy thunderstorm. We replace the interlock gasket with the correct density material that matches CGI’s extrusion profile.
- Slider lock strikes that won’t line up after years of use. This is common across every CGI sliding glass door series. The strike plate shifts a few millimeters, or the lock barrel itself wears, and the door either won’t latch or won’t unlock without jiggling. We re-square the strike, adjust the lock throw, and if the barrel is shot we replace the whole mechanism with a match to CGI’s keyway.
- Weep hole blockages causing water to pool inside the track. Every CGI patio door has weep holes at the bottom of the outer track designed to drain water that gets past the first gasket. In Miami, dirt, pollen, and salt grime clog them quickly. Water then sits in the track, and that’s what kills rollers and corrodes the track base. We clear the weeps, verify they’re drilled at the correct diameter, and if the track is too far gone we re-treat or replace it.
- Glass seal failure showing up as interior fogging. CGI insulated glass units carry a solid warranty in their early years, but older Estate doors in Miami sometimes show condensation between the panes once the desiccant inside the spacer gives out. We measure the glass pack, order a matching IGU, and replace the glass without pulling the frame if the frame is still sound.
Our CGI Sliding Glass & Patio Doors Process
Here’s how a CGI door job goes when you call us in Miami, from first ring to final cleanup.
- 1
You call (844) 901-4551. A live person answers, day or night. We ask what the door is doing, which CGI series you have if you know it, and we schedule a visit that fits your life, not ours.
- 2
We diagnose in person. A background-checked, uniformed technician arrives and runs the door through its full range: roller load, track alignment, interlock seal, lock function, and glass condition. We measure, we listen, and we don’t guess.
- 3
You get a line-item written quote. Before any work starts, you see exactly what we’ll do and what it costs. No change orders that show up after the fact.
- 4
We make the repair. Parts sourcing depends on the door. For rollers, interlock gaskets, and locks, we match OEM where the part matters for warranty or lock integrity, and we use quality aftermarket alternatives where they’re genuinely equal or better, with your sign-off first.
- 5
We test the door. The door has to roll with even pressure, lock without resistance, and show no day gap at the interlock. We run water over the track and check the weeps drain correctly. We don’t call it done until it passes all of it.
- 6
We clean up and stand behind it. Old parts go with us. The work area gets swept. And every CGI repair is covered by our Done Right Promise. If it’s not right, we come back and make it right.
What CGI Sliding Glass & Patio Doors Costs in Miami
Every door is different, but here are the ranges we typically see on CGI sliders and patio doors in Miami, with the caveat that the exact number depends on your door’s series, size, and condition.
- Roller and track cleaning with new rollers: $185–$340 depending on panel weight and roller grade.
- Interlock gasket replacement: $120–$260, more if the extrusion itself is bent and needs re-alignment.
- Lock mechanism replacement with OEM-style keyway match: $175–$390.
- Full door re-tune (rollers, track, interlock, lock, weep clearance): $450–$760 on most CGI sliders.
- Full CGI slider replacement including frame and install: $1,800–$4,200, with M-Series and high-end lines at the top of that range.
What moves the price is mostly glass size and frame condition. Corroded tracks a previous owner ignored, rollers that seized and scored the aluminum, or a door that’s been out of square for years all add labor. That’s why we quote only after we see the door. The estimate is free, and we’ll show you the numbers before any commitment. Call (844) 901-4551 to get yours.
Why Miami Homeowners Call Winslow Windows & Doors for CGI Work
Because Ed Winslow’s name is on the permit. Ed grew up in Hialeah and spent years working window and door installs across Miami before he started Winslow in 2011, so he’s seen every way a patio door can fail in this climate and fixed most of them twice. We’re not a national chain that sends whoever’s on the schedule. We’re the one down the road, with a published address, a license number, and a phone that always gets answered by a live person.
And because we install eight brands, including PGT, CWS, ES Windows, and ECO Window Systems, we’re not going to sell you a replacement when a repair is the right call. We work on your CGI door because that’s what you have. If it’s beyond saving, we’ll tell you straight and show you options with numbers attached. Every CGI repair and install is backed by our Done Right Promise. It’s not a slogan. It’s a hundred-year standard we stand behind on every job from Coral Gables to Cutler Bay.
FAQs
No, generally not. As an independent CGI service provider, we install parts that match the manufacturer’s spec and we never modify the frame or glass package in ways that would void coverage. For roller, lock, and interlock work, the original door warranty typically stays intact. Call (844) 901-4551 if you want us to check your specific door and warranty status before we start.
Some are. Older Estate and Targa series parts, especially original roller carriages, aren’t stocked by every supplier. We keep common rollers, interlocks, and lock sets on hand for current and common older CGI models, and we have local Miami suppliers who carry what we don’t. For a specific part on your door, call (844) 901-4551 and we’ll tell you lead time before we schedule.
Repair makes sense when the frame is square, the glass is sound, and the failure is mechanical, like rollers, locks, or interlocks. Replacement makes sense when the frame is corroded through at the track, the glass seal has failed and the IGU costs more than half a new door, or your current door simply doesn’t meet the impact rating required for a Miami home anymore. We’ll quote both honestly, and you decide.
Most roller, lock, and interlock repairs are done in a single visit. Glass replacements and full door installs depend on lead time for the door or glass pack, which we’ll tell you at the quote. In an emergency, like a door that won’t close or secure, call (844) 901-4551 and we’ll make it a priority.
Yes, and these offers are permanent, not a promotion. We take $40 off any repair over $200, we provide a free second opinion on any written estimate, there’s no trip charge inside Miami-Dade County, and seniors and veterans always get a 10% discount. When you call (844) 901-4551, mention any of these that apply to you.
