AfterCGI Windows & Doors in Miami, CA | Westlight Windows & Doors
We provide independent CGI windows and doors service across Miami, and the one thing that makes our work here different is the Miami-Dade Notice of Acceptance system. A CGI unit sold anywhere else in Florida doesn’t automatically pass inspection here unless it carries the right NOA number. We’ve worked with CGI products in Miami-Dade for over a decade, so we check that before we touch a single screw. Call (903) 354-7134 for service, parts, or a straight answer about your windows.
Why Miami Residents Choose Us for CGI Service
Westlight Windows & Doors is an independently owned and operated Kingswell location, not a CGI authorized dealer. That independence matters more than most homeowners realize. We answer to you, not to a manufacturer’s sales quota, so when we look at a failed CGI impact window in Hialeah or a corroded sliding door in West Miami, we tell you whether it’s worth repairing or whether replacement is the honest call. Owen Satterfield, our owner, grew up watching his grandfather re-glaze windows on old craftsman bungalows in the Palms neighborhood of Los Angeles, then spent two decades installing and servicing windows across Southern California before building Westlight around one rule: tell the homeowner the truth about cost before anyone picks up a tape measure. That’s the standard we bring to every CGI job in Miami.
We use genuine CGI replacement components whenever they’re available, including rollers, operators, multipoint hardware, gaskets, and insulated glass units. When a CGI part is discontinued, we fall back to spec-matched aftermarket components and tell you we’re doing it. No silent substitutions. No surprise invoices at the door. The Kingswell Guarantee puts the written price, the arrival window, the clean job site, and the written workmanship guarantee in your hands before work starts.

Common CGI Windows & Doors Problems We Solve in Miami
These are the failures we see week after week in Miami service area homes, and each one has a local cause behind it:
- Roller and track degradation on CGI sliding doors. Miami’s salt-laden air off Biscayne Bay packs fine grit and corrosion into CGI horizontal roller tracks. Within five to seven years, doors bind, drag, or drop off the track entirely. We clean, replace rollers, and re-align tracks so the door moves like it did when it was new.
- Glazing seal failure on south- and east-facing CGI impact units. Miami’s UV intensity breaks down edge seals on insulated glass faster than almost anywhere in the country. You’ll see fogging or a silvery haze between the panes on south and east elevations first. That’s seal failure, not a structural problem, and it often means an IG unit replacement rather than a full window.
- Hardware and hinge corrosion on CGI doors and operators. Mill-finish or improperly coated hinges, multipoint locks, and window operators pit and seize in coastal salt air. We replace corroded hardware with properly coated components so the mechanism doesn’t fail again in two years.
- Water infiltration at the perimeter of CGI impact frames. Older CBS masonry homes with degraded sealant or missing end-dams leak during wind-driven rain. You’ll notice stained drywall or bubbling paint at the interior jamb. We find the actual entry point and fix it, not just caulk over the symptom.
- Jalousie-to-impact conversions done wrong. We regularly see jalousie openings in Little Haiti and Liberty City that were “converted” to impact windows without proper anchoring into the concrete block. The frame holds until the first real storm, then fails. We re-do the anchoring to Miami-Dade code.
CGI Service in Miami: What Local Conditions Mean for Your Equipment
Here’s the thing most window companies won’t tell you, and it’s the single biggest reason CGI service costs more in Miami than in Broward or Palm Beach: Miami-Dade County’s Notice of Acceptance system requires large-missile impact testing that exceeds the rest of Florida’s Building Code. A CGI window with a Florida Product Approval number from Broward County may not carry the Miami-Dade NOA number your permit requires. So the first step of any replacement here isn’t measuring the opening. It’s verifying the specific CGI model’s NOA against the county’s product control database. We do that on every single job, because a failed inspection means a failed final, and a failed final means your insurance discount never materializes. Owen’s rule applies here: tell me what you need, and I’ll tell you what it actually costs. That includes the cost of doing the NOA paperwork right the first time.
CGI Models & Products We Service in Miami
We service the full CGI catalog that’s relevant to Miami homes, including the SentinEL Series impact windows and doors, Sentinel Impact Series single-hung and double-hung units, 2- and 3-panel impact sliding glass doors, and custom fixed and awning impact units. For repairs, we stock common CGI rollers, operators, multipoint hardware, gaskets, and insulated glass units locally so Miami turnaround is measured in days, not weeks. For full replacements, we order directly with the NOA verification completed before the unit ships. That means no surprises at the building department.
CGI Service Pricing in Miami
Straight numbers, because that’s how we do business. A single CGI impact window replacement in Miami typically runs $1,800 to $3,800 installed, depending on size, frame condition, and whether we’re anchoring into wood or coring into CBS masonry. Jalousie-to-impact conversions in older block homes run higher, usually $3,200 to $5,500 per opening, because the work includes coring concrete, anchor-bolting, and often new interior trim. Roller and hardware service on a CGI sliding door runs $180 to $450 in most cases. A fogged IG unit replacement usually lands between $450 and $900 per sash. Every estimate is written, line-itemed, and handed to you before any work starts, and that price does not change at the door. Call (903) 354-7134 for an exact quote on your specific windows.

FAQs - CGI Windows & Doors in Miami
Yes, every CGI impact unit installed in Miami-Dade County must carry a Miami-Dade NOA number specific to that model and configuration. We verify the NOA against the county’s product control database before we order the unit, and we include the NOA number on your permit paperwork. If a contractor tells you any CGI window passes because it’s a Florida-approved product, that’s wrong. Florida Product Approval and Miami-Dade NOA are different standards, and Miami inspectors only accept the NOA. Call (903) 354-7134 and we’ll check your specific model while you’re on the phone.
No, in most cases you need a new insulated glass unit, not a whole new window. The frame, hardware, and impact glass on the outer pane are usually still sound. The fog means the edge seal between the panes has failed, which Miami’s UV intensity accelerates on south- and east-facing elevations. We replace the IG unit with a genuine CGI component or a spec-matched equivalent, and the window is clear again. If the frame is a discontinued era or the impact glass itself is compromised, we’ll tell you that honestly before you spend a dollar. Call (903) 354-7134 for a fogged-glass assessment and exact quote.
In a wood-frame house, you nail the flange to the studs and you’re done. In a CBS home in Hialeah or Little Haiti, the jalousie opening is set directly into poured concrete or CMU block with no wood buck. We core the masonry, insert anchor bolts or structural adhesive systems, and mount the CGI frame to that. It’s more labor, more time, and more cost, and any estimate that doesn’t account for it is wrong before it starts. In Little Haiti we replaced original jalousie windows in a 1960s CBS home with CGI SentinEL single-hung impact units, coring and anchor-bolting directly into the poured concrete because there was no wood buck to nail into. The homeowner’s wind-mitigation inspection after the permit final let her re-shop her policy, and she reported a premium drop that made the upgrade pay for itself sooner than she expected.
In most Miami homes, yes, and it’s often substantial. Florida’s property insurance market is in collapse, and carriers reward homeowners who eliminate the jalousie or non-impact windows that make a home a wind-mitigation risk. The typical premium reduction for a full CGI impact upgrade in Miami-Dade runs 20 to 45 percent annually, depending on your carrier, your home’s construction, and your wind-mitigation inspection results. The key is that the wind-mitigation inspector must see the proper NOA documentation and the proper anchoring, which is exactly what we provide. Call (903) 354-7134 and we’ll walk you through what your home qualifies for.
In most cases, that’s service, not replacement. Miami’s salt-laden air packs fine grit into CGI roller tracks, and the rollers corrode over five to seven years. We clean the track, replace the rollers with genuine CGI parts or spec-matched equivalents, and re-align the door. You’re usually looking at $180 to $450, far less than a new sliding glass door. If the track itself is pitted or the frame is bent, we’ll tell you and give you a written replacement quote. Call (903) 354-7134 and we’ll diagnose it over the phone or send a technician out.
