AfterCGI Construction in Miami, FL | Rowan Construction Group Miami
CGI impact window and door service in Miami requires more than product knowledge. It demands fluency with Miami-Dade County’s Notice of Acceptance system, the High-Velocity Hurricane Zone code layer that no other Florida county enforces with the same rigor. We provide independent CGI construction service across Miami, from impact window installation in Coconut Grove to full envelope retrofits in Allapattah, with every quote delivered in writing before work begins. Call (786) 321-4970 to schedule your free estimate.
Why Miami Residents Choose Us for CGI Service
We’ve been working with CGI products in Miami since before the current NOA database went digital. Grant Rowan, who learned the trade at Los Angeles Trade-Technical College and has run crews in South Florida for over a decade, built our process around a simple idea: measure twice, write it down, then build it. That discipline shows up in how we handle CGI’s product line.
We’re not a CGI-authorized dealer. We’re an independent contractor that knows the product well enough to source OEM parts for critical components, specify correct NOA numbers for permit submittals, and spot when an out-of-state supplier has shipped hardware that won’t pass Miami-Dade inspection. Our crews are background-checked and uniformed; a live person answers calls 24/7; and every visit produces a documented photo record, included as standard.
Our CGI sales & service approach means we work with what’s already in your walls. Whether you need a single fogged Sentinel Series unit replaced or a full StormGuard door system re-anchored to meet current HVHZ standards, we quote a flat written price with a written scope before anyone picks up a tool. Under Clause 1 of The Haven Standard, that’s non-negotiable.
Common CGI Construction Problems We Solve in Miami
- Salt-air corrosion of stainless steel rollers and hinges. Miami’s persistent salt-air environment accelerates pitting and seizing in CGI impact sliders within a few miles of the coast or bay. We see this regularly in Key Biscayne and Miami Beach installations where standard-grade hardware was originally specified. We upgrade to hot-dip galvanized or marine-grade stainless replacements that outlast the originals.
- Seal failure and fogging in insulated glass units. The combination of intense UV exposure and 75% average humidity breaks down CGI’s insulated glass seals faster than inland Florida markets. Fogged glass isn’t just a visibility problem; it signals degraded impact resistance. We source OEM CGI impact glass to restore the original rating.
- Frame warping and water intrusion from improper anchorage. Miami’s CBS construction demands specific flashing and anchorage methods that differ from wood-frame markets. In pre-1992 homes across Little Havana and West Flagler, we frequently find CGI units installed without proper roof-to-wall hurricane strap integration, leading to frame stress and leaks during seasonal pressure changes.
- NOA expiration causing permit failures. CGI products carry Miami-Dade County Notice of Acceptance numbers that expire or get superseded. We’ve seen rough inspections fail because a contractor used last year’s NOA for a current Sentinel Series spec. We verify every number against the live database before permit submittal.
- Insurance-driven upgrades on pre-Andrew inventory. Many Miami homes built before 1992 lack impact-rated glazing entirely. We replace non-compliant openings with CGI ArmorView or StormGuard systems that satisfy current wind-borne debris codes, often the only path to maintaining homeowner’s coverage at renewal.
BeforeAfterCGI Service in Miami: What Local Conditions Mean for Your Equipment
Miami-Dade County requires every impact window and door to have a valid Notice of Acceptance number on the permit submittal. Inspectors here will fail rough inspections for missing or expired NOAs, even if the product is rated elsewhere in Florida. This paperwork trap routinely delays out-of-state contractors unfamiliar with the local approval database.
We built our Miami service area workflow around this reality. Before we quote any CGI project, we pull the current NOA for the specific model line, verify it against the Miami-Dade product control office’s online system, and include that documentation in the permit packet. In a 2023 job on a 1950s CBS home in Little Havana, we replaced failed CGI impact windows with corroded rollers and fogged glass. We sourced new CGI Sentinel units with current NOA numbers, upgraded to stainless steel hardware, and properly flashed the openings. The homeowner passed final inspection without delays and noted a significant drop in street noise. That outcome depends on knowing Miami’s system, not just CGI’s catalog.
CGI Models & Products We Service in Miami
We work across CGI’s impact-rated residential line: Sentinel Series impact windows in single-hung, horizontal roller, and casement configurations; StormGuard impact entry doors and French door systems; and ArmorView impact sliding glass doors for patio and balcony openings. Each requires different NOA documentation and anchorage specs under HVHZ.
For critical components, we source OEM CGI parts: impact glass with original interlayer specifications, factory locking mechanisms, and approved frame extrusions. When OEM hardware is backordered, we use high-quality aftermarket seals and fasteners that meet or exceed Miami-Dade’s corrosion-resistance standards, never compromising the impact rating. Our local supplier relationships mean most Sentinel and StormGuard parts are available within 48 hours, not the two-week freight timeline from out-of-state distributors.

FAQs - CGI Construction in Miami
Do CGI impact windows meet Miami-Dade HVHZ requirements?
Yes, CGI’s Sentinel Series, StormGuard doors, and ArmorView sliders carry Miami-Dade County NOA numbers when properly specified. The product itself is only half the answer; the installation must also meet HVHZ anchorage and flashing standards. We verify current NOAs on every job. Call (786) 321-4970 to confirm your specific model’s compliance.
My CGI impact window is foggy-can it be repaired or does it need replacement?
Fogging means the insulated glass seal has failed, which degrades impact resistance. We can replace just the glass unit with OEM CGI impact glass if the frame is structurally sound and under 15 years old. Older frames or coastal corrosion often make full replacement more cost-effective. Call (786) 321-4970 for a free assessment.
How does salt air affect CGI impact doors and windows?
Salt air accelerates corrosion of steel rebar, anchor bolts, and metal fasteners in concrete, and does the same to the rollers and hinges in CGI impact sliders. Within three miles of Biscayne Bay or the Atlantic, we specify upgraded stainless or hot-dip galvanized hardware as baseline, not an upgrade. Call (786) 321-4970 to check what grade is currently in your frames.
Can you install CGI impact windows in a historic Miami Beach Art Deco building?
Yes, with additional permitting. Miami Beach’s historic preservation review requires aesthetic compatibility documentation alongside standard HVHZ submittals. We’ve navigated this dual-track process for CGI installations and Miami Bathroom Remodeling in the Art Deco district, specifying custom finishes and maintaining sight-line requirements. Call (786) 321-4970 to discuss your specific property.
What’s the typical timeline for a CGI window replacement in Miami?
From signed contract to final inspection, most residential CGI replacements run four to six weeks in Miami. Permit review takes 10-14 business days; product lead time varies by model; and we schedule installation outside active hurricane warnings. Rush timelines compress when NOA documentation is complete from day one. Call (786) 321-4970 to confirm current scheduling.
