CGI Custom & Geometric Windows in Davie: What to Know First
We provide independent CGI custom and geometric window service in Davie, typically completing measured surveys within 48 hours of contact and delivering written quotes that do not change once work begins. Most custom CGI installations run four to eight weeks from signed quote to final inspection, depending on factory lead times for shaped and oversized units. This page is for Davie homeowners who already own CGI products or are specifying them for new custom openings - arched transoms, circular accent windows, trapezoid combinations, or oversized impact-rated geometric assemblies - and want a technician who understands how CGI’s lamination and reinforcement differ from PGT or CWS equivalents. Call (754) 254-8492 to schedule your measured survey.
How CGI Products Fail - and How We Fix Them
- Escalade Series fixed geometric units: The thermal break in Escalade’s aluminum frame can separate at the miter joints of custom angles, especially in Davie’s cycle of high humidity followed by dry winter air. We see this most in 45-degree and 30-degree trapezoid combinations above entry doors. Our fix is a full-frame replacement with factory-specified corner keys and a silicone structural back-bedding that CGI specifies for coastal exposure zones, not the standard butyl tape used inland.
- Sentinel by CGI impact-rated custom shapes: The laminated glass in Sentinel geometric units can develop edge delamination when the polyvinyl butyral (PVB) interlayer is exposed to standing water in the sill during our summer storms. The symptom is a milky perimeter that looks like fog but does not wipe away. We replace with OEM lamination or, when lead times stretch past 12 weeks, a Miami-Dade-approved equivalent from our ES Windows or ECO Window Systems lines with matching missile-impact certification.
- Sparta Series radius and arch-top windows: Sparta’s roll-formed aluminum is lighter than Escalade’s extruded frame, which means custom curved tops can sag at the springline if the reinforcing strut was omitted or undersized during original manufacture. We measure the deflection with a straightedge and specify either a factory-reinforced replacement or a site-installed stainless steel strut - the latter only when the original warranty period has expired, to avoid coverage disputes.
- CGI oversized fixed picture units: Custom dimensions exceeding 72 inches on either axis require heavier glazing packages that stress the balance shoe system in any operable companion sash. We find this in Davie’s newer construction near Pine Island Ridge, where builders spec’d large geometric combinations without upgrading the hardware. Our repair replaces the balance system with a weight-rated alternative from the same OEM lot, documented with the serial number for your record.
- Coastal bronze and dark anodized finishes on custom shapes: CGI’s darker anodized coatings chalk faster in Davie’s UV exposure, particularly on south and west-facing geometric accent windows where the profile complexity creates micro-crevices that hold salt. We do not attempt spot refinishing on custom shapes - the color match is unreliable. We quote full-unit replacement with either a factory re-anodize order or a shift to a powder-coat equivalent from PGT or CWS if the project timeline demands it.
Our CGI Custom & Geometric Windows Process

- 1
Measured survey you keep: Sonia Raman or a verified crew member arrives with a laser measure and a printed template for your specific geometric configuration. You receive the dimension sheet before we leave. Measure it right the first time. Everything else follows from that.
- 2
Diagnostics and failure documentation: We photograph the existing unit - frame readings, glazing edge condition, hardware stampings, and any visible deflection - then note the CGI series, manufacturing date code, and original order number if available.
- 3
Parts decision with written rationale: We specify OEM CGI components when factory lead times are under eight weeks and the unit remains under warranty. For out-of-warranty jobs or extended lead times, we document the Miami-Dade-approved equivalent from CWS, ES Windows, or ECO Window Systems and explain the performance match in writing.
- 4
Installation under Haven Clause 3: The technician who arrives is the technician on the record - background-checked, uniformed, license number provided in advance. No subcontractor rotation on custom work.
- 5
Testing and evidence: We operate every moving component, verify the sightline is plumb and level to 1/8 inch, and photograph the completed installation from inside and out. The photo record uploads to your file within 24 hours.
- 6
365-Day Done Right Promise activation: The written warranty references the Haven Standard by clause. If the seal fails, the frame deflects, or the finish chalks prematurely, we return and make it right - no requote, no argument.

AfterWhat CGI Custom & Geometric Windows Costs in Davie
These are the ranges we have written in Davie over the past 24 months for CGI custom and geometric work. Your measured survey determines the exact figure.
| Scenario | Typical Range |
|---|---|
| Standard geometric replacement (trapezoid, triangle, octagon) - Escalade or Sentinel, under 40 sq ft | $1,800 - $2,800 per opening |
| Custom arched or radius top - Sparta or Escalade, including reinforced frame | $2,400 - $3,900 per opening |
| Oversized fixed geometric unit - over 72″ on any axis, impact-rated | $3,500 - $5,200 per opening |
| Multi-unit geometric combination (transom + sidelite + shaped accent) | $5,500 - $9,000 per assembly |
| Site measure and written quote (Haven Clause 1) | No charge |
What moves the price: factory lead time for custom extrusions (expedited orders add 15-25%), scaffolding or interior protection for oversized units, and whether the original opening requires structural reframing for impact-rated replacement. We do not quote until we measure. Call (754) 254-8492 for your written estimate - estimates are free.
Why Davie Homeowners Call Sightline Windows & Doors Davie for CGI Work

We are an independent CGI service provider - not affiliated with or authorized by CGI - which means we source across eight manufacturer lines to match what your opening actually requires. If CGI’s factory is backordered on a custom Escalade arch, we can specify a Miami-Dade-approved equivalent from PGT, CWS, ES Windows, or ECO Window Systems with matching impact and energy performance, documented in the same written quote.
Since 2012, every one of our 18,000+ installations has carried a written price before work started and a documented photo record when finished. Our 365-Day Done Right Promise is written into the Haven Standard, not offered as a courtesy. In Davie, we have completed CGI work in Pine Island Ridge and surrounding neighborhoods where the combination of older framing and newer impact codes demands exact measurement - the kind Sonia Raman learned at Los Angeles Trade-Technical College and refined over two decades in the field. Calls are answered by a live person, 24/7.
FAQs
No - the factory warranty on CGI’s frame and glass remains intact as long as the installation follows the manufacturer’s published guidelines and uses OEM or approved equivalent components. We document every specification in your file so warranty claims are supported. Call (754) 254-8492 if you need a warranty review - estimates are free.
Standard custom shapes from CGI’s Florida facility typically ship in six to eight weeks; complex radius work or oversized units can extend to ten to twelve weeks. We quote the current lead time in writing at the time of your survey and update you if factory schedules shift. Call (754) 254-8492 for current availability - estimates are free.
Impact-rated laminated glass cannot be field-repaired - the interlayer and glass assembly must be replaced as a unit to maintain missile-impact certification. For non-impact geometric units out of warranty, we evaluate whether a glazing-only replacement is feasible, though most Davie homes require impact-rated replacement per current code. Call (754) 254-8492 and we will assess your specific unit - estimates are free.
We have encountered this on older Sparta Series custom shapes. Our response is to measure the existing frame and glazing pocket precisely, then specify the closest current CGI profile or a cross-compatible equivalent from CWS or ES Windows with documented performance match. You receive the comparison in writing before any order is placed. Call (754) 254-8492 to discuss your specific profile - estimates are free.
Yes - any impact-rated replacement or structural modification requires a Broward County permit, and we include permit pulling in our written scope. We also schedule and pass the required inspection, documented with a photo record of the approved installation. Call (754) 254-8492 to confirm permit requirements for your project - estimates are free.
