CGI Custom & Geometric Windows in Tampa: What to Know First

We provide independent CGI custom and geometric window service in Tampa, from full replacements and retrofit installations to repair work on arched, radius, and oversized openings. Most CGI jobs are quoted within two business days, and the work itself typically runs one to two days depending on the number of openings and whether we’re matching existing frames or rebuilding rough openings. Pricing runs honest and upfront: you’ll see line items on paper before any work starts, not a vague number that drifts once we’re on the ladder. If you own a CGI home in Tampa and the windows are fogging, binding, or leaking, call (813) 320-9346 and we’ll schedule a time to look.

This page is for homeowners who live behind CGI products and want custom and geometric work done right the first time. As an independent CGI service provider, we are not a CGI factory arm and we don’t pretend to be. We’re a glazing company in Tampa that has worked on enough CGI installations to know exactly where they hold up and exactly where they give way.

How CGI Products Fail - and How We Fix Them

CGI builds a solid impact product, but no window line is perfect. Here are the failure patterns we see on custom and geometric CGI windows in Tampa, model line by model line, along with what we do about them.

• Estate Collection radius units and seal failure at the springline. The Estate Collection is CGI’s premium custom line, and the arched and radius units use bent glass set into heavy aluminum frames. In Tampa’s humidity, the seal at the springline, which is the exact point where the straight jamb transitions into the curve, is the first place the insulating gas escapes. The symptom is a fog line that starts at the curve and creeps downward. The fix is a full insulated glass unit replacement. We don’t drill and patch seals on curved glass; it never holds and it voids what is left of the warranty.
• Custom geometric windows in the 200/400 series losing their square due to racking. We see a lot of trapezoids, triangles, and pentagons in Tampa homes built in the 1990s and early 2000s, many of them CGI 200 or 400 series. Those custom shapes put enormous stress on the frame corners, and if the original installer didn’t block the rough opening properly, the frame racks over time. The glass doesn’t break, but the sash binds and the weatherstripping tears. Our fix is to pull the unit, re-square the rough opening with proper blocking, reset the frame, and replace the damaged weatherstripping strips before rehanging the sash.
• Vertical mullion failures on oversized CGI window walls. Tampa homeowners with big water views often have CGI multi-panel window walls, and those panels are joined with vertical mullions that carry a lot of structural load. When those mullions flex during storms, water finds the seam at the mullion cap. The tell is a water stain on the interior drywall directly below the mullion line. The real cause is usually the mullion being under-supported at the sill, not a bad seal. We fix it by removing the mullion cap, installing the proper splice reinforcement, and resealing with a manufacturer-spec structural sealant, which is a different product than the caulk you buy at the hardware store.
• Aftermarket glass in an original CGI frame. Not every previous homeowner used a qualified glazier. We’ve walked into Tampa homes where a CGI frame holds a piece of aftermarket glass that doesn’t carry the right laminate thickness for the original design pressure rating. The window looks fine until it doesn’t. We verify the glass make-up against the original order, and if the glass isn’t what the frame was engineered for, we quote a proper replacement. An impact window with the wrong glass is just a really heavy regular window.
• Custom transoms and half-rounds over CGI doors: sill rot from condensation channel clogs. Geometric transoms and half-rounds over doors and side lights collect condensation at the bottom of the shape. CGI sashes have weep channels that drain that water, but in Tampa’s climate those channels clog with pollen, mildew, and the fine grit our rain carries. The result is water backing up in the sill track and wicking into the frame. We pull the sash, clean the channels, and in severe cases re-mill the weep notches so the drainage slope is restored.

Our CGI Custom & Geometric Windows Process

Here’s how a CGI custom or geometric window job runs with us, from the first call to the final walkthrough.

1. 1
   We answer the phone and ask the right questions. You’ll speak to a person, not a menu. We ask about the window shape, its location, when the problem started, and whether you have the original order paperwork. That paperwork matters because it tells us the exact glass package and pressure rating we need to match.
2. 2
   We measure the opening twice and inspect the frame. Custom and geometric openings require exact measurements because a triangle or arch does not tolerate slop the way a standard rectangle does. We measure every side, check the diagonals, and inspect the rough opening for rot, racking, or prior installation shortcuts.
3. 3
   We quote manufacturer line by manufacturer line, on paper. If your job involves new units from CGI, we quote those side by side with comparable options from other lines we carry so you see the trade-offs in front of you. For repairs, we quote OEM CGI parts when warranty-safe and quality aftermarket parts when the warranty is long expired and aftermarket offers the better value. You’ll know which is which before we order a single piece.
4. 4
   We do the work in a clean, organized sequence. Lead time depends on the complexity of the custom shape and the material already in the opening. When the day comes, our team is uniformed, background-checked, and treats your home the way we’d treat our own mother’s house. Protection goes down before any window comes out.
5. 5
   We test, then test again. Once the new unit is set and sealed, we cycle the sash, check the lock points, run water over the exterior under pressure when the situation allows, and then walk the inside with a flashlight to look for any glass defects or frame gaps. If something is off, it gets fixed before we leave. If the pane isn’t true, the job isn’t done.
6. 6
   Then we register both warranty layers, in writing, before we pull away. You get documentation listing the manufacturer warranty duration and our own 90-Day Done Right Promise. Nothing gets left to a conversation in the driveway.

What CGI Custom & Geometric Windows Costs in Tampa

Custom and geometric work is unlike standard window replacement, because every curve, angle, and radius carries its own manufacturing cost. The framer doesn’t just pull a stock size off the shelf.

The biggest cost drivers are the number of custom angles or radii in the shape, whether the opening needs structural work, and whether we’re matching existing window tint or custom glass make-ups. A simple rectangle in a good opening is a straightforward job. A true arch with a complicated springline is a different animal. Call (813) 320-9346 with the rough dimensions and shape, and we’ll give you an exact quote. Estimates are free, and fixed pricing means the number we write down is the number you pay.

Why Tampa Homeowners Call TruePane Windows & Doors for CGI Work

Dale Kessler grew up in Seminole Heights back when the neighborhood was more bungalows and screen porches than craft cocktail bars, and he still lives about six blocks from where he learned to ride a bike. He picked up the glazing trade at Hillsborough Community College’s construction technology program, spending more time on the shop floor than in a classroom seat, and for the better part of two decades he has been measuring, setting, and sealing windows and doors across the Tampa Bay area. The work he is best known for is storm-rated installation done tight enough that a follow-up inspection is never a surprise. That’s the standard every TruePane technician works to.

We’re an independent CGI service provider, which means we’re not tied to a single manufacturer’s playbook. When we quote a CGI job in Tampa, we also bring knowledge of the other lines we install and service: PGT, CWS, ES Windows, and ECO Window Systems. If a CGI part is backordered or a specific custom shape has a long factory lead time, we’ll tell you what your alternatives are, honestly. Our 90-Day Done Right Promise covers the workmanship. If it’s not done right, we make it right. No paperwork, no arguing. And when you call (813) 320-9346, a live person answers, day or night.
