This page is for Miami Springs homeowners who bought CGI windows because they wanted hurricane protection that didn’t look like prison bars. You paid for engineering. You deserve service that respects the product. Ed Winslow has been working on South Florida windows since 2011, and he grew up right here in Miami Springs, not far from the old Curtiss Parkway strip. We know these homes, we know these windows, and we know what salt air and summer humidity do to them.

How CGI Products Fail - and How We Fix Them

CGI makes a serious impact window. But Miami Springs weather doesn’t care how much you paid. Here’s what we actually see on service calls:

• Sentinel series seal failure at the radius. The Sentinel line shows up in a lot of Miami Springs mid-century ranches, and the arched tops are the weak point. The curved glass unit flexes more than a flat pane under thermal load, and after eight to ten years the seal at the radius starts to let go. You’ll see fogging at the top of the arch first. We replace the insulated glass unit, not the whole window, and we check the frame for racking before we order anything.
• Estate series roller wear on oversized sliders. CGI Estate sliders are heavy, and the factory rollers are fine until they’re not. On wide openings in Miami Springs living rooms, we see the rollers flatten over time, which makes the panel drag and then bind. The fix is a roller swap with a commercial-grade replacement, and while we’re in there we clean the track and adjust the panel height so the lock lines up like it did on day one.
• Geometric fixed windows settling out of square. This isn’t a CGI manufacturing defect. It’s a framing issue. In older Miami Springs homes, the rough opening moves over decades, and a geometric window that’s been pinched at one corner will eventually crack the glass or pull away from the caulk line. We shim, re-seat, and re-seal, then verify the reveal is even all the way around before we call it done.
• Tuscany series hardware corrosion. The Tuscany line is popular in Miami Springs for its look, but the standard hardware doesn’t love our humidity combined with salt in the air. We see pitting on handles and lock mechanisms after a few years, especially on canal-side properties. We replace with marine-grade hardware where possible and lubricate the linkage so it doesn’t seize.
• Custom trapezoid and circle-top windows with leaking flashing. Any custom geometric shape creates more flashing seams than a standard rectangle, and more seams means more places for water to get in. On CGI custom units in Miami Springs, a leak at the top of a circle-top window is almost never the glass. It’s the flashing above it. We remove the exterior trim, inspect the water barrier, and re-flash the opening properly. Then we water-test before we put the trim back.

Our CGI Custom & Geometric Windows Process

Every CGI job we do in Miami Springs follows the same path, no shortcuts:

1. 1
   Call and diagnosis. You tell us what’s wrong. We ask questions that tell us whether it’s a glass issue, a hardware issue, or a framing issue. If it’s a geometric window, we get the dimensions and shape specs so we’re not guessing.
2. 2
   In-person inspection. We come to your Miami Springs home, measure, inspect, and photograph. You get a written line-item quote. The price on that paper is the price you pay, period.
3. 3
   Parts decision. For glass replacement, OEM is the default on CGI windows under warranty or in visible areas where tint and clarity matter. For hardware, we’ll tell you honestly when a quality aftermarket part is the smarter spend and when it isn’t.
4. 4
   The work. Our techs arrive in uniform, background-checked, and ready. We protect the work area, replace or repair the unit, and clean up like we were never there.
5. 5
   Testing. We operate every function, check the seal, and for arced or shaped units we verify the reveal and the caulk line. Then we walk you through what we did.
6. 6
   The Done Right Promise. If it’s not done right, we make it right. That’s not a slogan. That’s Ed’s name on the line.

What CGI Custom & Geometric Windows Costs in Miami Springs

Here’s what Miami Springs homeowners can expect to pay for common CGI service scenarios.

• Insulated glass unit replacement on a standard CGI SENTINEL single-hung: $425 to $780 installed
• IGU replacement on a CGI SENTINEL ROUND TOP (radius arch): $580 to $980 installed
• CGI TUSCANY casement or awning operator and hinge set replacement: $240 to $450 installed
• CGI ESTATE sliding glass door roller replacement and track realignment: $300 to $550 installed
• Custom geometric CGI fixed window reglazing and flashing repair: $480 to $1,050 installed
• Full replacement of a standard-size CGI SENTINEL single-hung window: $1,100 to $2,400 installed

What moves the price: the shape of the glass, the size of the glass, and whether the frame itself is still sound. A circle-top costs more to fabricate than a rectangle, and a window on the second floor costs more to install than one at ground level. You’ll know your exact number before we start.
