AfterCGI Custom & Geometric Windows in Margate: What to Know First
We install and service CGI custom and geometric windows in Margate as an independent CGI service provider, with most measured surveys completed within 48 hours and written quotes delivered before any work begins. Typical custom CGI orders run 4-8 weeks from sign-off to installation depending on shape complexity and glass specification. Our pricing starts at $890 for standard geometric shapes and ranges upward based on actual opening measurements, not estimates.
This page is for Margate homeowners who already own CGI products or are specifying them for new construction, renovation, or impact upgrades in neighborhoods like Holiday Springs Village, where we regularly see 1980s-era openings that were never designed for modern geometric glazing. If you’re comparing CGI against other impact-rated options, we also specify PGT, CWS, ES Windows, and ECO Window Systems by performance requirement, not inventory convenience. Call (754) 254-7558 to schedule your measured survey.
How CGI Products Fail - and How We Fix Them
- Escalade Series fixed geometric gaskets pull away at radius points. The curved aluminum extrusions in arched and half-round configurations expand and contract differently than straight stock in Margate’s humidity cycles. We’ve replaced dozens of these in Coral Gate and Oriole homes where the original gasket was field-cut too short. We measure each radius with a contour gauge and order factory-length gasket stock, then bed the joint in neutral-cure silicone rated for South Florida UV exposure.
- Sentinel by CGI impact-laminated geometric units delaminate at the sightline. The interlayer separates when the insulated glass unit (IGU) experiences thermal stress from west-facing exposure without adequate frame ventilation. Our fix: we specify tempered-over-laminated rather than standard laminated construction for geometric units above 40 square feet, and we verify the weep system is clear before the new unit goes in.
- Sparta single-hung custom shapes develop sash drift in oversized openings. The balance shoe geometry wasn’t designed for the added weight of impact glass in trapezoid or pentagon configurations. We replace the standard balance system with a heavy-duty spiral-tilt assembly rated for the actual sash weight, and we shim the frame to plumb within 1/16 inch so the load tracks true.
- ClearView casement geometric hardware binds at the hinge side. The multi-point locking system on custom-angled casements was specced for rectangular frames; when CGI machines the stile to a non-standard angle, the deadbolt throw can miss the keeper by 3-4 millimeters. We mill a custom strike plate in-shop or source the corrected OEM bracket when available, then test the full throw cycle under load before we leave.
- Coastal Solutions fixed picture windows with integrated geometric tops leak at the mullion joint. The combination frame uses two different extrusion profiles meeting at a horizontal joint; the factory sealant bead often skips the interior corner. We remove the affected unit, clean both extrusion chambers, and apply a continuous backer rod and sealant bead that bridges the profile transition. We’ve documented this repair with photo records on at least a dozen Margate homes built between 2004 and 2012.
Our CGI Custom & Geometric Windows Process
- 1
Measured survey you keep. Sonia or a verified crew member arrives with a printed license number, measures the rough opening to 1/8 inch, and notes wall thickness, header condition, and any out-of-square condition exceeding 1/4 inch. You receive this document before we leave.
- 2
Written scope and price. Haven Clause 1: the quote matches the survey exactly. For CGI custom work, we specify series, glass package, exterior finish, and hardware finish by code. No allowances, no “plus materials” language.
- 3
Parts decision documented. We mark OEM versus quality aftermarket on the written scope. For discontinued CGI profiles, we source matching extrusion from certified secondary mills or machine adapters in-house. You see the choice in writing before ordering.
- 4
Installation with evidence. Verified crews arrive on schedule per Haven Clause 2. We photo-document rough opening condition, shimming, fastener pattern, sealant application, and final sightline alignment. These images go to you with the invoice.
- 5
Test and sign-off. Every operable unit cycles 25 times. Impact-rated units get a visual interlayer inspection. We clean the glass and leave the documented photo record behind.
- 6
365-Day Done Right Promise activated. If the sash drifts, the seal leaks, or the hardware binds in the first year, we return and make it right. Written into the Haven Standard, not offered as a courtesy.

AfterWhat CGI Custom & Geometric Windows Costs in Margate
These are actual ranges from our written quotes in Margate and nearby Broward County jobs over the past 18 months. Your measured survey determines the exact figure.
| CGI Custom & Geometric Scenario | Typical Range |
|---|---|
| Standard geometric fixed unit (circle top, half-round, quarter-round) under 24 sq ft | $890 - $1,450 |
| Large geometric fixed unit (over 40 sq ft) with impact-rated laminated glass | $2,200 - $3,800 |
| Custom-shaped operable casement or awning with hardware | $1,600 - $2,900 |
| Oversized rectangular with integrated geometric top (combination frame) | $3,100 - $5,400 |
| Field repair: gasket replacement, hardware realignment, sealant restoration | $340 - $780 |
| Full IGU replacement in existing CGI geometric frame | $680 - $1,350 |
What moves the price: actual square footage (we measure, not guess), glass specification (impact-laminated versus tempered versus insulated), exterior finish (standard bronze/white versus custom Kynar coating), and whether the existing frame can be preserved or must be re-flashed. Coastal exposure within two miles of the Intracoastal may trigger additional fastener and sealant requirements per current Florida Building Code.

Why Margate Homeowners Call Sightline Windows & Doors Margate for CGI Work
We’ve installed and serviced windows and doors across more than 18,000 openings since 2012, and a significant share of those have been in Broward County neighborhoods where CGI products were specified by original builders or subsequent renovation contractors. Sonia Raman grew up in Miami, trained in glazing fundamentals at Miami Dade College’s Building Construction Technology program, and has spent the better part of two decades reading rough openings and specifying the right glazing package for actual site conditions. In Margate, that means knowing which streets in Holiday Springs Village still carry single-pane aluminum frames that were never built for today’s wind-load requirements, and which CGI series can replace them without structural modification.
Our multi-brand capability matters when a CGI lead time doesn’t match your project schedule. We specify PGT, CWS, ES Windows, and ECO Window Systems by performance tier and price range, not by margin. Every technician is background-checked, uniformed, and identified by license number before arrival. Calls are answered by a live person, 24/7. And the 365-Day Done Right Promise applies to every job, stamped under the Haven Standard.
Measure it right, write it down, then cut.
FAQs
No, provided the work is performed to CGI’s installation guidelines and uses OEM or equivalent-specification parts. We document our methods with the photo record you receive, and we flag any condition that might affect manufacturer coverage before we start. If your CGI windows are still under the original limited warranty, we’ll note that on your written scope and recommend whether a factory-authorized inspection makes sense for your specific issue. Call (754) 254-7558 and we’ll review your warranty status at no charge.
Standard geometric shapes from CGI’s current production lines typically ship in 4-6 weeks; complex custom angles, oversized units, or non-standard finishes can extend to 8-10 weeks. We don’t quote delivery dates we can’t verify. Your written scope includes the expected ship week based on CGI’s confirmed production schedule at the time of order, and we update you if that shifts. For time-sensitive projects in Margate, we maintain relationships with CWS and ES Windows that sometimes offer shorter lead times on comparable impact-rated geometric units. Call (754) 254-7558 to discuss your schedule.
Most CGI geometric units can be repaired if the frame extrusion is sound and the glass is the only failed component. We replace IGUs, gaskets, hardware, and sealant systems in the field. Replacement becomes necessary when the frame has corrosion at the weep channels, the extrusion is a discontinued profile we can’t match, or the geometric shape was custom-machined and the original CAD file is lost. Our measured survey determines which path applies; you’ll get our recommendation in writing with both options priced if both are viable. Call (754) 254-7558 for a free evaluation.
We stock common CGI hardware, gaskets, and sealants for field repairs, but geometric-specific extrusions and custom-cut glass must be ordered to the measured opening. For standard repairs, we often complete the work on the return visit after the survey. For custom glass or extrusion, the repair follows the manufacturing lead time. We don’t promise same-day completion on planned custom work; we do promise a written timeline you can plan around. Call (754) 254-7558 to schedule your survey and we’ll give you the real lead time for your specific repair.
No. Haven Clause 1 governs every engagement: the written quote derived from your measured survey is the final price. The only circumstance that changes the figure is concealed structural damage we couldn’t detect during survey, such as a rotted header or compromised sill plate, and we document that condition with photos and stop work for your approval before any additional scope is added. In 18,000+ openings, this has happened on fewer than 3% of jobs. Your written quote is the document we both sign; the invoice matches it. Call (754) 254-7558 to schedule your free measured survey.
