AfterCGI Custom & Geometric Windows in Coral Gables: What to Know First
Custom and geometric CGI windows in Coral Gables typically run $1,800 to $6,400 per opening depending on shape complexity, glass package, and whether the frame is standard or custom-bent. Most repair work on existing CGI geometric units takes one to two days once parts arrive, and we quote every job in writing before any work begins. This page is for Coral Gables homeowners who own CGI windows or doors and need straight answers about service, repair, replacement, and what it actually costs. Call (954) 507-3613 and a live person answers, day or night.
How CGI Products Fail - and How We Fix Them
CGI builds a solid product, but Coral Gables tests every window with salt air, hurricane seasons, and a brutal summer sun that does not let up. Here’s what we actually see on CGI custom and geometric units in this area:
- Geometric frame corner seal separation on CGI Estate Collection units. Arched and radius windows flex at the mitered corners more than rectangular frames, especially on western elevations where afternoon heat cycles run a hundred degrees above night lows. The corner seal eventually opens and lets moisture into the frame channel. We disassemble, clean, and re-seal with a marine-grade adhesive, then water-test before we call it done.
- Radius glass fogging between panes on CGI Sentinel series. The Sentinel line uses a rolled aluminum radius track, and the curved insulated glass unit (IGU) is the weak point along the bottom of the arc. Condensation you cannot wipe off means the IGU seal has failed. We measure the exact radius and order a replacement unit that matches the original bend, not a generic curved panel.
- Sash misalignment on oversized CGI casement and fixed geometric combinations. Big trapezoid and circle-top units paired with operating sashes put load on the hinge side. Over time the sash drops a few millimeters and drags on the sill. The fix is a re-shim and track adjustment, not a new window, unless the frame itself has twisted.
- Hardware galling on CGI impact-rated operator cranks. Salt in the air works on the crank gears and hinge pins faster than the manufacturer’s torque spec anticipates. We strip, clean, and lubricate with a dry-film lubricant, and replace worn gears with genuine CGI parts when the crank has visible tooth wear.
- Improper flashing on original installations of geometric units. We see this on houses built in the early 2000s around the Biltmore and Deering Bay neighborhoods. The window itself is fine; the original installer never sloped the sill pan or lapped the flashing tape correctly, so water travels behind the frame. This is a removal-and-reinstall repair, not a patch job, and it is the only way to stop the leak for good.
Our CGI Custom & Geometric Windows Process
Every CGI job we take follows the same sequence, and we do not skip steps because the shape is unusual:
- 1
Call and diagnosis. You describe the symptom. We ask specific questions about fogging, binding, leaks, or crank feel. If a picture helps, text it. A live person takes the call.
- 2
On-site measurement and inspection. A technician measures every opening twice, checks the existing frame condition, verifies glass thickness and impact rating, and notes the CGI series if the label is still legible.
- 3
Written quote with both options. We price OEM CGI parts and quality aftermarket equivalents side by side on paper. You see exactly what you are buying and what the warranty covers for each.
- 4
The work. We set the window, seal it, shim it, and test it. No change orders. No mystery line items.
- 5
Water test and walkthrough. Every geometric window gets a hose test on the exterior perimeter before we pack up. You see it hold dry with your own eyes.
- 6
Warranty registration on the spot. Both manufacturer warranty layers get registered in writing before our truck leaves your driveway. If it is not in writing, it is not a guarantee - it is just a conversation.
What CGI Custom & Geometric Windows Costs in Coral Gables
Straight numbers, based on what we’ve quoted across Coral Gables in the past few years:
- Radius glass replacement (fogged IGU): $850-$1,900 per unit, depending on arc length and whether it’s laminated impact glass.
- Corner seal repair on a geometric frame: $400-$900 per window, including disassembly, cleaning, sealant, and water test.
- Hardware rebuild (crank, hinges, tracks): $250-$600 per sash.
- Full custom geometric replacement window: $2,200-$6,400 per opening for a standard trapezoid or circle-top; larger or multi-panel radius units run higher.
- Flashing correction and reinstall: $700-$1,800 depending on stucco access and how much of the exterior needs to be cut back.
What moves the price: the complexity of the shape, whether scaffolding or lift access is required, glass package, and whether we are repairing an existing frame or ordering a full new unit. We do not give ballpark numbers over the phone and then change them on site. Call (954) 507-3613 and we’ll measure, quote, and stick to the number. Estimates are free.

FAQs
No, not when the repair is done with compatible parts and performed without altering the structural frame or impact rating. We document every step, and we register both manufacturer warranty layers in writing when a new unit is installed.
Yes. We measure the arc with a profile template, not just a tape measure, and order the replacement glass to that specific radius. Getting the template right is the difference between a window that fits and one that binds in the frame.
Most custom replacement orders arrive in three to five weeks depending on the manufacturer’s schedule and impact-glass availability. Repairs on existing frames typically take one to two days once parts are in hand.
If the frame is straight, the seal failure is isolated to the glass unit, and the window is less than twenty years old, replacement of the IGU usually makes sense. If the frame is corroded or the original install was improperly flashed, full replacement is the honest answer. We quote both paths and let you decide with real numbers in front of you.
Yes. We come out, measure, assess, and hand you a written quote with no charge. Call (954) 507-3613 to schedule a time, and a live person will pick up.
