CGI Impact Windows & Doors in Florida City: What to Know First

We install and service CGI impact windows and doors in Florida City as an independent CGI service provider, not an authorized dealer. Most CGI jobs we handle run from a measured survey to completion in two to five business days, depending on whether the glass is in regional stock. The price you receive after our survey is the price on the final invoice - Haven Clause 1, no exceptions.

This page is for Florida City homeowners who already own CGI products or are comparing them against PGT, CWS, and other impact-rated lines we carry. If you need impact-resistant windows, hurricane impact windows, single hung impact windows, double hung impact windows, horizontal roller and sliding impact windows, or vinyl impact windows, call (786) 418-6182 to schedule your free estimate.

How CGI Products Fail - and How We Fix Them

• Sentinel by CGI single hung sashes drop or bind in the track. The balance shoe wears asymmetrically in Florida City’s salt-air environment, especially on east-facing elevations near Homestead Bayfront Park where we have done repeat work. We replace with OEM-spec balance assemblies and verify the sash drop rate against AAMA 101/I.S.2-17 before we leave.
• WinGuard horizontal rollers develop hard rolling and eventual frame stress cracks. The stainless steel roller axle corrodes at the interface with the nylon wheel; owners feel resistance before they see rust. We pull the sash, measure axle diameter to 0.001 inch, and install either OEM or AAMA-verified aftermarket rollers - documented in your photo record.
• WinGuard vinyl frame corners gap after thermal cycling. South Florida’s afternoon rain followed by direct sun creates expansion differentials at the fusion-welded corners. We do not caulk over this; we assess whether the corner weld has structurally failed and recommend sash or frame replacement based on DP rating retention.
• Impact glass delamination at the edge bite. CGI’s laminated impact glass can show edge haze or separation when the interlayer degrades from UV exposure at the glazing pocket perimeter. We check whether the failure is cosmetic or structural per ASTM E1886, and we source replacement IGUs from verified distributors - never field-laminate, which voids the product warranty.
• Estate Collection double hung top sash won’t stay open. The constant-force balance spring fatigues faster in homes without overhang protection, common in Florida City’s newer construction. We match spring poundage to the actual sash weight, not the original sticker, because field moisture gain in wood-core sashes changes the load.

Our CGI Impact Windows & Doors Process

1. 1
   Measured survey. Sonia Raman or a verified crew member records every opening to 1/16 inch, notes frame condition, and identifies the CGI series and manufacturing date code. You keep this document.
2. 2
   Diagnosis with options. We tell you whether the fix is component-level, sash-level, or full replacement, and we name the price for each path before any work starts.
3. 3
   Parts decision. OEM CGI parts when available and warranted; AAMA-verified aftermarket when lead times or cost structure favor it. We document the source on your work order.
4. 4
   Installation and testing. We verify operation force, locking engagement, and weatherstrip compression. Impact-rated units get a visual seal inspection; we do not guess at pressure rating retention.
5. 5
   Photo record and sign-off. Before-and-after images, thermal images where insulation performance is in question, and your signed completion form. The 365-Day Done Right Promise attaches automatically.
6. 6
   Cleanup and documentation. You receive the final invoice, which matches your written quote, and access to your photo record. Measure it right the first time. The wall does not accept revisions.
