CGI Custom & Geometric Windows in Mangonia Park: What to Know First
Custom and geometric CGI windows in Mangonia Park can be repaired or replaced by an independent specialist without voiding your warranty, as long as the work follows OEM-compatible practices. Most jobs run from measurement and template work to finished install in two to four weeks depending on glass lead time, and a typical custom CGI repair in this area falls between $450 and $2,400 while full replacements start around $1,800 per opening. We’re an independent CGI service provider, not a factory rep, which means we tell you the truth about what your window needs instead of steering you toward whatever helps the manufacturer hit a quarterly number.
This page is for Mangonia Park homeowners who have CGI windows with arched tops, radius corners, trapezoids, circles, or oversized fixed panes, and who need someone who can actually source, build, or repair those shapes correctly. Call (561) 928-0302 and you’ll get a live person, not a call tree.
How CGI Products Fail - and How We Fix Them
- Radius and arch transom seal separation on CGI Estate Collection units. Curved glass puts constant stress on the butyl seal where the IG unit meets the frame. After eight to ten years in Mangonia Park’s humidity, we routinely see fogging start at the apex of an arch, not the bottom. The fix is a new curved IG unit templated to the exact radius, not a caulk smear over the failure.
- Sentinel Series geometric frames racking in oversized openings. A five-foot by five-foot fixed trapezoid weighs more than installers expect, and if the rough opening wasn’t reinforced at the header, the frame twists slightly. You’ll notice the operable sash next to it starts dragging. We pull the frame, reinforce the opening per current code, and reset the unit square.
- Tru-Guard laminate peeling at the edge of sharp-cornered custom shapes. Triangular and parallelogram windows concentrate stress at the acute corners. On older CGI doors and fixed lites, the impact laminate can delaminate right at those points. We replace the glass pack with the correct laminate thickness for the shape and exposure, and we don’t reuse old glazing tape.
- Water intrusion at the mull joint on joined custom configurations. When two or three geometric CGI units are mulled together to fill a feature wall, the factory mull cap relies on sealant that bakes out after a decade of South Florida sun. Mangonia Park afternoon thunderstorms find that seam fast. We split the mull, clean both frames, and re-join with a commercial-grade structural mull and new cap.
- Balance failures on CGI vertical sliders retrofitted into shaped openings. Some Mangonia Park homes have rectangular sliders framed into arches with fixed radius tops. The constant weight and humidity mean the block-and-tackle balances wear out in five to seven years. We swap in replacements sized for the heavier sash, and we do the same for the heel bead and sash lock while we’re in there.
Our CGI Custom & Geometric Windows Process
- 1
You call, a person answers. Ed or one of his office staff picks up at (561) 928-0302. We ask what the window is doing, what shape it is, and when you first noticed the problem.
- 2
We template and diagnose on site. For any curved, arched, or odd-angle opening, we take a physical template, not just measurements. This step is where most CGI work goes wrong, and it’s why we don’t quote unusual shapes over the phone.
- 3
Parts decision: OEM when it matters, proven aftermarket when it doesn’t. For laminated impact glass and frame extrusions, we use CGI-compatible or OEM stock. For balances, weatherstripping, and hardware, we often use aftermarket parts that outlast the original spec. We tell you which is which and why.
- 4
Install or repair with the opening protected. We don’t leave a hole in your wall overnight. If a custom unit is being fabricated, we tarp and board the opening properly, and we schedule the reinstall the day the glass arrives.
- 5
Test and walk you through it. We run the window through its full travel, check the seal with a moisture meter, and show you exactly what we did. If it’s an operable window, you operate it before we leave.
- 6
The Done Right Promise kicks in. If something isn’t right, we come back. That’s the end of the discussion. It’s been that way since 2011.
What CGI Custom & Geometric Windows Costs in Mangonia Park
Straight numbers, no games. Here’s what we see in Mangonia Park:
- Arched or radius transom reglaze (fogged seal): $450-$900 per unit, templated and set
- Custom geometric fixed window replacement (trapezoid, circle, triangle): $1,800-$3,600 per opening, depending on size and glass type
- Oversized Estate or Sentinel Series fixed lite replacement: $2,400-$4,800, including reinforced framing if the old opening isn’t square
- Mulled custom configuration repair (water intrusion or racking): $600-$1,800, depending on how many units and what seal work is needed
- Balance and hardware rebuild on a shaped vertical slider: $280-$600 per sash
What moves the price: glass type (laminated impact costs more than annealed), whether the frame needs resetting, and how far the opening is out of square. Mangonia Park homes built before the mid-90s often have rough openings that settled, and we’ll tell you honestly if that’s adding cost before we start. Call (561) 928-0302 for a free written estimate. The price we quote is the price you pay, no change orders unless you ask for extra work.

FAQs
No, as long as the repair follows OEM-compatible practices and uses the correct glass, frame, and sealant specifications. As an independent CGI service provider, we document everything we do so your warranty stays intact. If you’re unsure, call (561) 928-0302 and we’ll walk through what your specific window needs before we touch it.
Yes, we template every curved opening on site rather than relying on measurements alone, which is how we match the radius exactly. This matters because CGI arch units from different production years can vary slightly, even on the same home. We’ve seen a quarter-inch difference between two “identical” transoms on the same front elevation.
Repair is almost always cheaper when the frame is sound and the issue is the glass seal, hardware, or balances. Replacement makes sense when the frame is racked, the mull joint has failed, or the laminate is peeling on a sharp-cornered shape. A new custom IG unit typically runs a third to half the cost of a full replacement. Call (561) 928-0302 for an honest assessment, not a sales pitch.
Typical lead time is two to four weeks from template to install, depending on the glass type and whether it’s laminated impact-rated. We never promise same-day turnaround on custom shapes because rushed templating is how you end up with a window that doesn’t fit. We’ll give you a firm date when we order the glass, and we’ll hit it.
Yes, we do new-construction and retrofit installs for custom and geometric CGI windows, including oversized openings that need header work. We pull permits where required and pass inspection before we call the job done. The Done Right Promise applies to every opening we touch.
Call (561) 928-0302 to schedule your free estimate. A live person answers, day or night. We’ll come out, take a real look at your CGI windows, and give you a written price that won’t change when the truck pulls up. The one down the road.
