CGI Custom & Geometric Windows in Tampa: What to Know First
CGI custom and geometric windows in Tampa can be repaired, reglazed, or replaced by our crew without pulling permits on most residential jobs, and most single-unit work is completed in one to two visits. Typical repair work on a CGI radius or trapezoid unit in Tampa runs $350 to $1,200 depending on glass type, frame condition, and whether we’re dealing with an impact laminate or a standard insulated unit. We’re not a CGI dealer and we don’t pretend to be one. We’re an independent CGI service provider with fifteen years of callbacks on these exact frames.
This page is written for Tampa homeowners who already own CGI windows, specifically the shaped units: arches, circles, triangles, trapezoids, radius tops, and oversized picture windows. If you call the office at (386) 559-6999, a live person picks up. That’s not a slogan. That’s how Ed runs the place.
How CGI Products Fail - and How We Fix Them
Every window brand has its personality. CGI’s is this: the frames are built like bank vaults, but the seal systems on custom geometries work harder than they should. Here’s what we actually see in Tampa homes:
- Radius-top sweep failure on CGI Estate Collection units. The curved glass in a radius or arch top puts uneven pressure on the glazing bead at the apex. On east-facing Tampa exposures, the morning heat expands the aluminum, and over five or six years the bead pulls away just enough to let humid air into the insulated space. You’ll see fogging that comes and goes. The fix is a full deglaze and reseal with fresh setting blocks, not a “fog kit.” Fog kits are a band-aid on a bullet wound.
- Geometric corner seal rot on oversized trapezoids. CGI builds a solid window, but any shaped window with a sharp angle is stress-concentrating at that corner. We’ve pulled trapezoids in Carrollwood and Westchase where the corner seal failed and water wicked down into the sill track. By the time the homeowner notices a stain on the drywall, the sill is already corroding. We replace the sill, re-fabricate the corner gasket, and reseat the glass with marine-grade sealant.
- Impact laminate clouding on CGI Sentinel and Estate lines. Tampa’s humidity plus a slow seal leak equals a milky haze between the glass and the impact laminate. That’s not condensation you can wipe away. That’s the laminate bonding failing. It’s not a warranty issue if the window is out of its coverage window, but it’s absolutely repairable: we remove the sash, separate the laminate, clean the interlayer, and re-bond under vacuum at our shop.
- Operable custom awnings that won’t stay open. CGI casement and awning hardware on shaped openings carries more glass weight than a standard rectangle. The friction hinges wear faster, especially on large-radius half-rounds. We see this constantly on 15-year-old installs in South Tampa. The fix is replacing the hinge set with a heavier-gauge aftermarket hinge rated for the actual sash weight, not whatever came off the factory line.
- Leaky transoms over entry doors. CGI transom units over front doors in Tampa get pounded by afternoon thunderstorms from June through September. The weep system on some older CGI transom designs simply can’t keep up with a three-inch-an-hour downpour. Water pools on the interior sill. We re-machine the weep slots, add a positive slope to the sill pan, and re-flash the exterior with a higher backdam.
That last one on the list? We fix more CGI transoms than any other single custom geometry. Tampa’s rainy season is brutal on architectural glass. It’s just the truth.
Our CGI Custom & Geometric Windows Process
Here’s exactly what happens when you call us about a CGI window that’s fogged, leaking, or hard to operate:
- 1
You call, a person answers. Day, night, doesn’t matter. We take the address, the window location, and a few photos by text if you’ve got them. No ticket number. No call center.
- 2
We send a tech who knows CGI geometry. Not a general handyman. Someone who’s re-glazed radius tops and knows what a trapezoid corner seal looks like when it’s failing from the inside.
- 3
We diagnose on site. We find the real cause: seal failure, hinge wear, sill pan design, or impact laminate delamination. You get a written line-item estimate before any work begins. No trip charge inside our home county.
- 4
We make the parts call with you. On newer CGI units under warranty, we’ll help you document the claim and use OEM glass. On units out of warranty, we’ll recommend whether OEM is worth the cost or whether a quality aftermarket insulated unit gets you the same performance for less. We don’t upcharge parts. We show you the invoice.
- 5
We do the repair at our shop or on site. Glass fabrication for custom shapes usually happens at our shop, then we install. Simple seal jobs and hardware swaps we do on the spot.
- 6
We test, then Ed signs off. Every CGI job gets a water test if it’s a seal issue, an operation cycle test if it’s hardware, and a daylight inspection from inside. Then it’s under the 36500-Day Done Right Promise. If it’s not done right, we come back and make it right.
What CGI Custom & Geometric Windows Costs in Tampa
Here’s straight talk on what we charge, based on fifteen years of Tampa jobs:
- Single radius-top or arch insulated unit, fogged: $450 to $800. Includes deglaze, glass fabrication, reseal, and re-install.
- Impact laminate delamination repair on a CGI Sentinel or Estate window: $300 to $650 per sash. Works only if the frame and seal system are still sound.
- Acute-angle geometric window with corner seal failure: $550 to $1,100. This is the most labor-intensive custom geometry; we re-fabricate the gasket, not just caulk it.
- Friction hinge replacement on a large CGI awning or casement custom shape: $180 to $400. Includes heavier aftermarket hinges sized to the actual sash weight.
- Full replacement of a CGI custom unit, impact-rated, large radius or trapezoid: $1,200 to $3,400. The swing is huge because it depends on glass size, impact rating, finish, and whether we can reuse the existing CGI frame.
What moves the price: glass area, shape complexity, whether the unit is impact-rated, and whether we’re repairing an existing CGI frame or building a new one from scratch. We give you a free estimate and a fixed number. Not a range that doubles when the invoice shows up. Call (386) 559-6999 and we’ll put a real dollar figure on it.
Why Tampa Homeowners Call Winslow Windows & Doors for CGI Work
Plenty of companies in Tampa will tell you they can fix a window. Most of them have never re-glazed a half-round in a 1940s bungalow in Seminole Heights or re-seated a trapezoid in a Davis Islands remodel. We have. Ed grew up in Miami and learned the trade at Miami Lakes Educational Center before spending close to two decades measuring, installing, and standing behind windows and doors across the Tampa Bay area. His name is on the door, literally. That matters when a complicated custom geometry goes wrong and you need someone who won’t walk away.
We’re also a PGT, CWS, ES Windows, and ECO Window Systems installer, which means if we open up a CGI window and find the frame is beyond saving, we can show you replacement options from four other proven impact brands, not just one. And every single job, from a simple seal repair to a full geometric rebuild, is covered by the 36500-Day Done Right Promise. If it’s not right, we make it right. Period.
Our techs are background-checked and uniformed. You’ll know exactly who’s walking up your driveway. And when you call, a real person answers, 24/7. We also knock $40 off any repair over $200, give a free second opinion on any written estimate from another company, and offer a permanent 10% discount for seniors and veterans. Those aren’t promotions. They’re just how we work.
FAQs
Yes. Most CGI custom and geometric window repairs in Tampa don’t void the manufacturer’s warranty when done correctly: deglazing, resealing, hardware replacement, and sill work are all service operations. If your window is still under CGI’s factory warranty, we’ll document the failure and help you decide whether to file a claim. For units out of warranty, we repair with either OEM or spec-matched aftermarket parts, whichever gives you the better value for a Tampa climate.
We typically schedule diagnostics within a few days to a week depending on where you are in Tampa, and we’ll give you a written line-item estimate the same day we look at the window. Most single-window repairs are finished in one or two visits. Call (386) 559-6999 and we’ll get you on the schedule.
If the window is under warranty, we use OEM CGI glass. If it’s out of warranty, we compare OEM pricing with a high-quality aftermarket insulated unit made to the same dimensions and performance specs. On a large radius-top, OEM can cost two to three times more than a properly fabricated aftermarket unit with the same energy ratings. We show you both numbers and let you decide.
It depends on two things: the frame’s structural condition and the age of the glass. If a geometric window’s corner seal has failed and the aluminum frame is still sound, a repair costs less than half of a full replacement and can add ten-plus years to the unit. If the frame is corroded or the impact laminate is failing across the whole sash, replacement makes more sense. We get a free estimate either way. We’re not paid to sell you a new window. We’re paid to fix your problem.
No. We give a fixed, line-item price before any work begins, and that’s the number you pay. No change orders, no “we found something” upcharges. If we open the window and find a surprise, we stop, call you, and get approval before doing anything that would change the number. That’s just how we operate.
If you own a CGI custom or geometric window in Tampa and it’s fogging, leaking, or acting up, call (386) 559-6999 for a free estimate. A live person will answer. A real fix will follow. The one down the road.
