CGI Impact Windows & Doors in Kendall: What to Know First
We provide independent CGI impact windows and doors service in Kendall, with most repair calls completed in one visit and full retrofits quoted from a measured survey you keep. Our written price before any work starts runs $180-$340 for common CGI hardware and seal repairs, and $890-$2,400 per opening for impact-rated replacements depending on series and glazing specification. This page is for Kendall homeowners who already own CGI products and need honest diagnostics, warranty-safe repairs, or a matched replacement that performs to the original rating. Call (786) 321-3319 to schedule your free measured survey.
How CGI Products Fail - and How We Fix Them
- Sentinel by CGI single hung sash drift. The balance shoe wears asymmetrically in Kendall’s salt-air environment, causing the sash to drop or tilt in its track. We see this most in units facing the Turnpike corridor where vibration compounds the wear. Our fix: replace the balance assembly with OEM-spec shoes and re-square the jamb liner, not the sash itself. We document the frame plumb before and after.
- Impact-rated horizontal roller hard roll and track gouging. The stainless steel tandem rollers on Estate Collection sliders seize when debris packs the bottom rail, then the sash drags aluminum into the vinyl track. Homeowners notice it first as resistance, then as a grinding sound during hurricane prep. We pull the sash, clean the rail cavity, replace with sealed-bearing rollers rated to the original DP, and photograph the track profile for your record.
- Sentinel double hung top-sash lock failure. The zinc die-cast tilt latch cracks after repeated cycling, especially where morning sun hits the upper sash and thermal expansion stresses the mechanism. We match the latch by die stamp, not by visual similarity; aftermarket latches that look right often fail to engage the keepers at full tilt, compromising the impact rating. We test three-point engagement before we leave.
- Fixed picture window seal breach in coastal exposure. The warm-edge spacer on older CGI fixed units corrodes at the edge where Kendall’s driving rains sit against the frame sill. Fog between panes is the late symptom; early signs are a chalky residue at the glass edge we catch during survey. We replace the insulated glass unit with a matched OEM build, re-bed with neutral-cure silicone, and record the spacer lot number.
- Estate Collection multi-point lock misalignment after settling. Kendall’s oolitic limestone substrate shifts seasonally, and the three-point lock on Estate swing doors drags at the deadbolt. Other techs file the keeper or shim the strike plate; we measure frame square, adjust the hinge barrel, and reset the multipoint rod travel to factory spec. Filing the keeper voids the impact certification. We don’t do it.
Our CGI Impact Windows & Doors Process

- 1
Measured survey you keep. Sonia Raman or a verified crew member arrives uniformed with license number visible, records every opening’s rough opening, reveal, and sightline dimension, and leaves you the handwritten sheet.
- 2
Diagnostics with photo evidence. We photograph the failure mode, the product label (series, DP rating, glass spec), and any adjacent damage. You get these images same-day.
- 3
Parts decision: OEM or qualified equivalent. For warranty-active CGI units, we use OEM parts to preserve coverage. For out-of-warranty work, we source equivalent components from our verified supply chain, never generic hardware that lacks Miami-Dade NOA documentation.
- 4
Dry-fit before sealant. Every sash, frame, or glass unit is set without sealant first. We check operation, lock engagement, and sightline alignment. Measure once, document it, then cut.
- 5
Final test and photo record. We cycle every operable unit ten times, verify lock function under load, and photograph the completed installation. The written invoice matches the survey; no additions, no change orders.
- 6
Haven Standard closeout. The 365-Day Done Right Promise is stamped on your paperwork, and the photo record uploads to your job file by evening.

Why Kendall Homeowners Call Sightline Windows & Doors Kendall for CGI Work

We’ve measured and set frames in Kendall long enough to know which blocks were built with CBS block and which used wood frame infill, and how that changes the install approach for the same CGI series. Our crew is background-checked, uniformed, and identified by license number before arrival - Haven Clause 3, Verified Crews. If your CGI line is discontinued or the lead time doesn’t work, we specify from our other verified manufacturers: PGT, CWS, ES Windows, or ECO Window Systems, matched to the same performance tier, not whatever is in stock. The 365-Day Done Right Promise covers every job, and the photo record is standard, not an upsell. We’re independently owned and operated under the Haven Standard, not a franchise, and we’ve held to the same written-price principle since 2012.
FAQs
No. As an independent CGI service provider, we use OEM parts on warranty-active units and document the work to manufacturer standards. The warranty remains intact when the repair follows published guidelines and uses specified components. Call (786) 321-3319 and we’ll review your warranty status before scheduling.
Repair is viable when the frame is square, the glass is intact, and the failure is isolated to hardware or seal components. Replacement makes sense when the frame is compromised, the DP rating is outdated for current code, or repair parts are no longer manufactured. We give you both numbers in writing and let you decide. Call (786) 321-3319 for a free second opinion on any estimate.
Yes, for current-series color offerings. For discontinued CGI finishes, we source from verified custom coaters with AAMA 2605 certification, and we provide a physical sample for your approval before ordering. The match is documented in your job file. Call (786) 321-3319 to schedule a color audit.
Most hardware and seal repairs are completed in two to four hours on site. Insulated glass unit replacements require one return visit for installation after the custom build is complete, typically ten to fourteen business days. We give you both dates in writing at the survey. Call (786) 321-3319 to book.
Yes. Miami-Dade County requires permits for all impact-rated window and door replacements, with TAS 201 or ASTM E1886 testing documentation. We pull the permit, schedule inspection, and pass it before final payment. The permit number and inspection result are included in your job documentation. Call (786) 321-3319 to start the process.
