CGI Window Installation in Miami: What to Know First
CGI window installation in Miami typically runs $900 to $2,800 per opening depending on the series, size, and whether you’re replacing an existing impact unit or converting from standard glass. Most single-window installs are completed in one day; full-home CGI replacements usually wrap in two to four working days. We give you a written line-item price before any work starts, so there’s no mystery when the invoice arrives.
This page is for homeowners who already own CGI windows (or are about to) and need someone who actually knows how these products behave in Miami’s salt air, humidity, and hurricane wind loads. If you’re comparing brands, we’ll walk you through that too. Call (844) 901-4551 and you’ll get a live person, day or night.
How CGI Products Fail — and How We Fix Them
CGI builds a genuinely strong window. But Miami finds the weak points in everything, and after 15 years of installs across South Florida, we’ve seen exactly where these units give way. Here’s what we run into most often:
- Sentinela series rollers binding after storm-driven debris works into the track. The Sentinela horizontal roller has a tight bottom track that collects sand and shell fragments during coastal blows. Homeowners in neighborhoods like Coconut Grove and Key Biscayne call us with rollers that grind or stick. The fix is a full track clean-out, roller replacement where needed, and re-aligning the panel so it glides without leaning into the frame.
- Estate Collection casements with sagging hinge hardware. CGI’s casement windows are heavy. In older Miami homes with settling concrete-block walls, the hinge side takes stress the manufacturer’s torque specs don’t fully account for. We see this in neighborhoods like Shenandoah and Silver Bluff where houses date to the 1940s and 50s. We pull the sash, repair or replace the hinge set, and re-torque to spec so the vent won’t drag across the sill.
- Picture windows with compromised silicone bedding after Miami’s wet-dry cycling. Fixed CGI picture units rely on a perimeter seal that gets hammered by our rain-dry-rain pattern. When water finds a pinhole, you’ll see condensation between the panes or a slow drip along the interior sill. We remove the glass pack, clean the rebate, re-bed with the right marine-grade silicone, and re-tape the perimeter. It’s a careful job that keeps the warranty intact.
- Awning windows on older homes with stripped operator gears. The operator mechanism on awnings and hoppers wears out faster than the window itself. In Coral Gables and the Roads, where awnings vent bathrooms and kitchens, we replace more operator gears on CGI units than any other component. Parts are available; the trick is getting the right gear tooth count for the series, which we do before we ever show up.
- Single-hung windows where a past installer shimmed the frame crooked. This isn’t a CGI problem; it’s an installation problem. But it shows up on CGI units all over Miami because so many homes got impact retrofits during the post-Andrew building boom, and some of those crews moved fast. A window that never quite latches, or sticks when you lift it, is usually shimmed out of square. We pull it, reset it, and re-anchor it so the latching points actually line up.
Our CGI Window Installation Process
Here’s what an install looks like when we do it, from the first call to the last sweep:
- 1
Call and schedule. You reach a live person at (844) 901-4551 any time. We ask about your windows, your home’s construction type, and what you’re seeing. Then we book a time that works for you.
- 2
Measure and assess. We measure the rough opening, check the existing anchors, and look for what caused the problem in the first place. If it’s a failed install on a decent window, we tell you. If the window itself is done, we say that too. No pressure either way.
- 3
Written line-item quote. You get the number before we touch anything. It covers materials, labor, disposal, and any permit work. Fixed price, no change orders unless you ask for something different.
- 4
Install day. Our background-checked, uniformed technicians show up on time. We protect your floors, pull the old unit, correct any framing or anchoring issues, set the new window, case it out, and seal it properly for Miami’s wind and water loads.
- 5
Test and walkthrough. We operate every sash, check every latch, and spray the perimeter to make sure nothing’s getting through. Then we walk you around the job so you can see what we did and why.
- 6
Cleanup and guarantee. We haul away the old window and leave the room cleaner than we found it. Then the job is covered by our Done Right Promise: if it’s not done right, we make it right. Period.
What CGI Window Installation Costs in Miami
Here’s what we typically see for CGI work in Miami, based on the window type and what the job involves:
- Single or double hung CGI replacement: $900 to $1,600 per window, installed.
- Horizontal roller (Sentinela or similar): $1,100 to $2,000 per unit, depending on width.
- Casement replacement: $1,300 to $2,400 per window, hardware included.

- Full-home CGI replacement (10-15 openings): $14,000 to $35,000, with permit and disposal included.
What moves the price: the series, the size, whether existing anchors can be reused, and whether we’re pulling a permit (we do, when the job requires it). Seniors and veterans get 10% off, permanently. Call (844) 901-4551 for an exact quote on your windows. Estimates are free.
Why Miami Homeowners Call Winslow Windows & Doors for CGI Work
We’re an independent CGI service provider, not a manufacturer rep, and that matters more than most people realize. Our loyalty is to the homeowner, not to a sales quota. Ed Winslow grew up in Hialeah, learned construction at Miami Dade College’s Wolfson Campus, and has spent well over a decade focused on windows and doors in South Florida. His name is on the permit, and that means he’s not going anywhere until it’s right.
The Done Right Promise covers every install we do. A live person answers our phone 24/7, no voicemail loops. Every technician is background-checked and arrives in uniform. If your home has a mix of brands (it happens all the time in Miami), we also install PGT, CWS, ES Windows, and ECO Window Systems, so you’re not juggling contractors. And we stand behind the work with upward pricing that doesn’t shift once the job starts. No surprises on the invoice.
FAQs
Yes, in most cases CGI’s warranty assumes installation was completed by a qualified professional using proper anchoring and sealing methods. Improper install is the leading cause of denied impact-window claims in Miami. If you’re considering it, call us first at (844) 901-4551; a conversation costs nothing and can save you thousands.
A single window usually takes one day from removal to cleanup. A full home of 10-15 openings typically runs two to four working days, depending on the condition of the existing openings and whether we’re pulling permits. We’ll give you a timeline in writing before we start.
If the frame is structurally sound and the glass pack is intact, repair usually makes sense for things like rollers, operators, and seals. If there’s frame rot, failed glazing, or the window no longer meets Miami-Dade wind load requirements, replacement is the honest call. We’ll tell you which path we’d take if it were our house, and we’ll give you both prices before you decide. Call (844) 901-4551 to have someone look at it.
Most common CGI components (rollers, operators, latch sets, weather-stripping) are available locally or within a few days through our supplier network. Series-specific parts, like Sentinela track assemblies or Estate hinge sets, sometimes require a special order. We plan for that and let you know before you commit to the job.
