Why Miami Homeowners Choose CGI Construction
Mason Remodeling Co Miami provides independent CGI construction repair and Miami Cgi service across Miami, from Coral Gables to Miami Shores, focusing on the CGI Sentinel, Estate Collection, 9500 Series, and Commercial Storefront systems common in coastal homes. We are not authorized by CGI, and we will not claim to be. What we bring is a decade-plus of hands-on failure diagnosis on Miami’s specific problem: salt air corroding hardware, hurricane cycles stressing seals, and original installs that never accounted for concrete block expansion. Call (850) 780-8123 when a CGI window binds in its track or a sliding door starts scraping.
CGI products are built for impact. Miami is built for humidity, salt, and wind. Those two realities intersect in ways the product spec sheet doesn’t cover, and that gap is where we work.
Why Trust Mason Remodeling Co Miami for Your CGI Construction?
Our crew pulls CGI sashes apart weekly, and we have seen the same failures repeat across hundreds of Miami homes. The difference between a technician who “works on impact windows” and one who knows CGI specifically shows up in the parts order. The wrong roller assembly, installed slightly off-spec, will bind again by the next hurricane season. The right one, torqued correctly into pre-drilled concrete, holds for years.
Isaac Pruett, our owner, started on framing crews before he had a driver’s license, earned his construction trade certificate from Los Angeles Trade-Technical College, and spent years working rough framing, finish carpentry, tile, and drywall before bringing his operation to South Florida. He has been reading job sites in Miami for over a decade, including Cgi in Miami Beach and throughout Coconut Grove. His approach has not changed: diagnose the real problem, put the number in writing before work begins, and stand behind it for 365 days after completion. If something is not right within that year, we fix it at no cost.
Every crew member who arrives at your door is background-checked, identity-verified, in a clean marked uniform, and carrying photo ID. You receive the technician’s name and photo before the visit. That is the Threshold Standard, and it applies to every job, including CGI service.

Common CGI Construction Problems We Fix in Miami
- CGI Sentinel Storm Windows: seal failure at the sash corners. After repeated impact cycles and years of Miami’s salt air, the gaskets at the corners lose their compression. Moisture gets in, the stainless rollers start corroding, and the sash binds in the track. We replace the gaskets and rollers with OEM CGI parts, not generic copies that deform in our heat.
- CGI 9500 Series Sliding Glass Doors: worn roller assemblies that scrape the bottom track. Salt and sand accumulate in the track channel. If the door is forced when the rollers are seized, the tempered glass carries stress it was never designed to take, eventually shattering. We rebuild the roller assemblies and re-align the panel before that happens.
- CGI Estate Collection fixed windows: stress cracks radiating from the frame screws. This is an installation defect as often as a product issue. When original crews over-torqued mounting screws into concrete block without pre-drilling, the frame flexes with every thermal cycle, and cracks grow outward from each screw head. We see this most often in mid-century Miami condos where replacement windows went into 1950s block walls.
- CGI roof-to-wall flashings on additions: UV-brittle cracking. Miami’s sun is merciless on exterior metals and sealants. Flashing that looked fine five years ago starts splitting along crease lines, then wind-driven rain from a summer thunderstorm tracks into the drywall. We replace with gauged material and re-seal with products rated for our UV index.
- CGI Commercial Storefront Systems: door closer sag in humid months. Storefront closers that work fine in winter start lagging by August. The adjustment is rarely the issue. We find worn pivot shoes and misaligned top pivots from years of coastal air working on the hardware. Shim stock, new pivot assemblies, and a correct closer re-adjustment solve it without re-hanging the door.
CGI Parts & Our Repair-vs-Replace Approach
For CGI windows and doors, we insist on OEM gaskets, rollers, and balance springs. Aftermarket copies are cheaper on the invoice but fail within a season in Miami’s heat due to plasticizers breaking down in the polymer. We will not install a knockoff roller in an impact-rated window and call it done. On cosmetic trims and interior stops, when original CGI profiles are discontinued, we fabricate matched-quality replacements locally in aluminum or PVC to preserve the original look.
The repair-vs-replace decision is straightforward. If the glass is intact and the frame is solid, we repair the hardware. If the frame has twisted from a failed anchor, or the glass shows impact stress beyond a simple crack, we will tell you it is a replacement and explain why. As your General Contractor, we have no incentive to sell you a window you do not need. We do have every incentive to make sure the repair does not fail, because our 365-day promise means we would be back for free. For a specific quote on your CGI repair, call (850) 780-8123.
Our CGI Service Process – Step by Step
- 1
Diagnosis. Our technician arrives with a photo ID you already received by name. We pull the sash or panel, check the rollers, gaskets, anchors, and seal condition, and identify the failure. For CGI specifically, we verify the design pressure rating label is intact and legible, because that label matters for your Miami-Dade code compliance.
- 2
Written price before any work starts. You get a line-item quote, in writing, before a single tool is unpacked. Not a verbal estimate. Not a range that grows later. The number you see is the number you pay.
- 3
Repair or install. We use OEM CGI parts where they matter, follow the product’s anchoring and torque specs, and pre-drill when working into concrete block. For new impact window installations, this means code-compliant anchoring and sealed perimeters that stand up to inspection.
- 4
Testing. The sash cycles smoothly. The seal compresses evenly. The door latches without lifting. For impact windows, we confirm the frame is square and the glass carries no new stress points.
- 5
Warranty. Every completed project carries a written guarantee with terms we state plainly, plus a free return visit if the repair or install fails. We back it for 365 days from completion.

One call, one written price, one responsible party: (850) 780-8123.
FAQs – CGI Construction Service in Miami
The glass is fine. The whistle is air moving through a gap at the sash corner where the CGI gasket has lost its compression, common after several years of Miami heat cycling. Replacing the gasket and re-seating the sash stops the whistle without touching the glass. Call (850) 780-8123 for a diagnosis; the fix is often done same visit.
In most Miami homes, yes. The new panel and roller assembly can be fitted into the existing CGI frame if the frame is square and the track is not heavily corroded. We measure, confirm the opening dimensions against the 9500 Series spec, and give you a written price before any work starts. If the frame has twisted, we will tell you before we quote, not after we start.
Yes. Concrete block requires pre-drilling and the correct anchor type and torque spec. Over-torquing causes exactly the stress cracks we see in older Miami condos. Our installers follow CGI Construction in Doral, FL standards for anchoring schedules on block walls, and we verify the design pressure rating label remains intact after the install is complete.
Usually not. Sag is most often worn pivot shoes or a misaligned top pivot from years of coastal air and humidity working the hardware. We replace the pivot assembly, shim as needed, and re-adjust the closer. If the frame itself has shifted, we will show you the measurements and explain what that means for the door’s operation.
Yes. We fabricate matched flashing locally using gauged material, and when the original color is no longer in production we color-match against a sample from your roof or wall. The match will be close, and more importantly the flashing will be sealed correctly. A faded color match beats leaking flashing every time. Call (850) 780-8123 and we will look at the existing flashing before quoting.
