AfterTrusted Custom & Geometric Windows for Sarasota Homeowners
Custom and geometric windows in Sarasota typically run from $900 to $4,500 per opening depending on size, glass package, and the complexity of the shape, and most projects take four to eight weeks from measurements to installation. If you live in a home built before 2000, there’s a fair chance at least one opening in your house is not a stock rectangle, which means the big-box replacement route ends in a shrug and a patch job. TruePane Windows & Doors has been setting custom and geometric windows in Sarasota for decades, and Dale Kessler still checks every job against the same rule he wrote on the whiteboard years ago: if the pane is not true, the job is not done. Call (941) 214-2069 to talk to a person who knows the difference between a radius window and a true ellipse, and who can tell you on the phone whether your project is a standard order or a full custom fabrication.

What Our Custom & Geometric Windows Service Includes
Custom and geometric windows are exactly what they sound like: openings that deviate from the stock rectangles manufacturers keep on warehouse shelves. In Sarasota, that category covers a lot of ground. Some of it is architectural, like the half-round window above a front door in a Spanish Revival home in McClellan Park, or the trapezoid panels flanking a cathedral ceiling in a Lakewood Ranch great room. Some of it is driven by code, like impact rated shapes that must match the exact geometry of an existing opening in a coastal home where the wind-borne debris region rules what can be installed. And some of it is structural: an oversized opening in a mid-century house where the original framing was built around a custom glass package that no longer exists off the shelf. Whatever the reason the opening is not standard, the work is.
Custom Impact Windows
Custom impact windows take the same laminated glass and reinforced frame technology used in standard hurricane rated windows and apply it to non-standard shapes: arches, circles, trapezoids, triangles, and octagons. In Sarasota, where the wind-borne debris region covers much of the city depending on proximity to the Gulf and Sarasota Bay, these windows must meet Florida Building Code requirements for missile impact and cyclic wind pressure. TruePane orders the exact shape through PGT and CGI as an authorized installer, which means the pressure rating, the product approval number, and the design pressure calculations are specific to that opening, not borrowed from a similar sized stock unit. The two most common triggers for this job are a failed window in a home built before the current code where the owner wants the replacement to carry current impact ratings, and a remodel where the architect specified a shaped opening that must still meet the wind code.
Geometric & Shaped Windows
Geometric and shaped windows are the catch-all for any opening that is not a square or rectangle: triangles, trapezoids, parallelograms, pentagons, hexagons, and the odd clipped corner that builders used in entryways and stair landings. These windows are built to a specific set of degree angles and leg lengths, and the margin for error is measured in sixteenths of an inch because a shaped window that is a half degree out of square will bind against the rough opening and never seal correctly. Our technicians measure every opening twice before an order is placed, and the shop drawing comes back to you on paper so you see the exact geometry before fabrication begins. The most common request is a replacement for a builder-grade shaped unit that has lost its seal and fogged, which nearly always requires a full custom order because the original manufacturer dropped the shape or the company no longer exists.
Arched & Curved Windows
Arched and curved windows include true half-rounds, quarter-rounds, elliptical arches, eyebrow windows, and radius tops over rectangular sashes. The critical measurement here is the spring angle, which is the point where the curved section departs from the straight section, and getting that wrong means the curved portion will not match the framing and the reveal will be visibly uneven. TruePane has set arched windows in everything from 1920s bungalows in Gillespie Park to new construction in Palmer Ranch, and the process is the same every time: measure the radius at multiple points, confirm the spring line, and order the unit with the same arc tolerance the manufacturer specifies. In many of these homes, the arched window sits over a fixed window or a front door, so the framing details and the flashing sequence matter as much as the glass package itself.
Oversized Openings
Oversized openings are windows that exceed the maximum size a manufacturer builds in a standard series, which in the residential market usually means anything over 60 inches in either direction or glass packages that push past standard wind load limits. These are common in custom homes along the water in Siesta Key and Casey Key, where a wall of glass may run ten or twelve feet wide and eight feet tall with a single uninterrupted view. The work involves engineering calculations for dead load, wind load, and glass deflection, and the unit is built to order with a heavier frame profile and thicker glass package than anything you would find in a stock catalog. TruePane works directly with the manufacturer’s engineering team on oversized jobs, and the structural considerations are handled before the order is placed, not discovered in the field after the old window is out of the wall.

Brands We Service for Custom & Geometric Windows
TruePane is an authorized installer for PGT and CGI, which are the two dominant manufacturers of impact rated windows in Florida and the two names most Sarasota homeowners already know. Working through these lines matters for custom work because an authorized installer relationship means we fall under the manufacturer’s direct warranty program rather than a third party arrangement, and because the ordering system gives us precise control over the fabrication details that determine whether a custom shape fits correctly. For PGT, that includes their WinGuard and custom shape series with tinted and low-e glass options. For CGI, it includes their impact rated line designed for coastal exposure, which is often the right call for homes in the wind-borne debris region closer to the Gulf.
We also work with ES Windows, a manufacturer of custom aluminum frames that comes into play when a homeowner wants the narrowest possible sightlines on a modern home or when the opening requires a frame profile that vinyl and standard aluminum will not support. The point of carrying multiple lines is that we can quote the same shape from more than one manufacturer side by side on paper, so you see the price difference, the glass difference, and the frame difference before you write a check. Whether your current window is PGT, CGI, ES Windows, or any other make, we can match it, replace it, or rework the opening.
Signs You Need Custom & Geometric Windows Right Now
- Condensation or fog between the glass panes. When a sealed unit fails on a shaped window, the fog you see is moisture trapped between the panes, and it will not dry out. On a custom shape, the failed seal means a replacement unit must be fabricated to the same geometry, which is a job that should not wait because the argon or krypton gas has escaped and the window has lost most of its insulation value.
- Visible daylight or drafts around the frame. Shaped windows carry more sealant surface per square foot than standard windows, and that sealant breaks down over time in the Florida sun. If you can see light around the edge of an arch or trapezoid window, water and air are getting through, and the opening is no longer weather tight.
- Difficulty opening, closing, or locking the window. A shaped window that binds when you try to operate it is usually telling you the frame has racked or the hardware has worn past adjustment. On a custom unit, this is not a replacement part at the hardware store, and forcing the window will only make the frame worse.
- Rot, rust, or soft wood around the opening. By the time the trim around a shaped window shows visible rot, the rough opening behind it is usually wet too. In Sarasota’s humidity, that damage does not dry out on its own, and a custom window replacement will include refinishing the opening, not just swapping the sash.
- Cracks in the glass or a failed impact rating after a storm. A cracked pane in a standard window is bad; a cracked pane in an impact rated shaped window means the protective layer has been compromised and the opening no longer meets code. If your home is in the wind-borne debris region, that is a code compliance issue as well as a safety issue.
If any of these sound familiar, the next step is a phone call, not a trip to a home center. Call (941) 214-2069 and describe what the window is doing. We will tell you whether it needs a full replacement or whether a repair can buy you time.
Our Custom & Geometric Windows Process - Step by Step
- 1
Free in-home measurement and consultation. A background-checked, uniformed technician comes to the house and measures every opening twice, because a shaped window that is off by even a quarter degree will not fit correctly. We measure the leg lengths, the vertex angles, and the radius at multiple points on any curved unit, and we photograph the opening so the shop drawing matches the actual framing, not just the numbers in a form.
- 2
Side-by-side manufacturer quotes on paper. We walk you through the options from at least two manufacturers when the shape allows it, with the glass package, the frame material, the impact rating, and the manufacturer warranty duration written out line by line. You see exactly what you are buying and what it costs before any money changes hands.
- 3
Custom fabrication order with verified dimensions. Once you approve the quote, we place the order with the manufacturer using the full dimensional drawing. For complex shapes, we often work directly with the manufacturer’s engineering team on the details, especially when the opening is oversized or carries an unusual impact load requirement.
- 4
Installation by our own employees, not subcontractors. The crew that installs your window is on the TruePane payroll. They cut out the old unit, inspect the rough opening, repair or replace any framing damage they find, set the new window with the correct flashing and sealant sequence, and adjust the hardware until the window operates the way it should. We do not use day labor or third-party crews.
- 5
Warranty registration before we leave the driveway. This is the Keystone Standard, and it is the step most contractors skip. Before the truck leaves your property, both manufacturer warranty layers are registered in writing with your name, the product serial number, the installation date, and the warranty durations stated. We hand you the paperwork and we keep a copy. The 90-Day Done Right Promise covers the workmanship, and if anything is not right, we come back and make it right without arguing.
How Much Does Custom & Geometric Windows Cost in Sarasota?
A custom geometric window in Sarasota typically costs between $900 and $2,800 per opening for a standard shaped unit with mid-range glass, while full custom fabrication with impact rated glass, low-e coatings, and a premium frame material runs $2,500 to $4,500 or more per opening depending on size and complexity. An arched window of modest size usually lands between $1,200 and $3,000. A true custom oversized opening can exceed $6,000 when engineering calculations and structural frame work are required. These are honest ranges for the Sarasota market, not national averages that do not account for Florida code requirements and impact glass.
What moves the price: the size of the opening, the glass package, the frame material, the impact rating, the shape complexity, and whether the rough opening needs structural repair before the new unit goes in. The way to avoid overpaying is to get a written line-item quote that separates the unit cost from the labor cost from any framing repair from the flashing and trim work, which is exactly what TruePane provides. A free estimate from us includes a full dimensional measurement, side-by-side manufacturer pricing, and a written quote good for the work we discussed. No change orders, no surprise line items.

Frequently Asked Questions - Custom & Geometric Windows in Sarasota
Custom and geometric windows are windows with shapes beyond standard rectangles and squares, including arches, circles, triangles, trapezoids, hexagons, and oversized openings. They are fabricated to the exact dimensions of your rough opening rather than pulled from stock inventory. In Sarasota, many homes built before the pulse of modern tract housing have at least one non-standard opening, and replacing those windows correctly requires a company that measures and orders custom units rather than forcing a stock window into a shape it was not built for.
Most custom and geometric window orders take four to eight weeks from the day the measurements are approved to the day the window is set, because the unit is fabricated to your exact dimensions and shipped from the manufacturer. Installation itself is typically a single day per opening, though larger or structural jobs may run longer. When you approve the quote, we give you a written timeline and then we meet it. That is part of the 90-Day Done Right Promise and the standard we have kept for over four decades.
A custom geometric window in Sarasota generally runs $900 to $4,500 per opening, with the final number driven by size, shape complexity, glass package, impact rating, and whether the rough opening needs repair. A basic triangle or trapezoid replacement falls on the lower end, while a true arched window with impact rated glass and a premium frame lands higher. Call (941) 214-2069 for a free in-home estimate with side-by-side manufacturer pricing and a line-item written quote, and you will know your exact number before you commit to anything.
Yes. TruePane is an authorized installer for PGT and CGI, which means we order through their direct channels, the manufacturer warranty is registered in your name, and the fabrication specs come from the manufacturer’s engineering data rather than a generic template. This is a meaningful difference on shaped windows because the pressure ratings and product approvals are opening specific, especially for impact rated units in the wind-borne debris region of Sarasota.
If a shaped window is broken or has blown out and the opening is exposed, call us at (941) 214-2069 any time. A live person answers the phone twenty-four hours a day, seven days a week, and we can prioritize emergency board-up or temporary glazing for any opening. A full custom replacement still requires fabrication lead time, but we will secure the opening and get the replacement ordered the same day in most cases.
Every custom window we set is covered by two layers: the manufacturer warranty on the product itself and our 90-Day Done Right Promise on the workmanship. The Keystone Standard means both warranty layers are registered in writing before the truck leaves your driveway, with the durations stated and a copy in your hand. If something is not done right within 90 days, we fix it. No paperwork fights, no fine print, no arguing.
Clear the area around the window on both the inside and outside: move furniture at least four feet back, take down window treatments, and clear hedges or plantings from the exterior wall. Remove pictures and objects from nearby shelves, because the work involves some vibration when the old unit is cut out. Our crew covers the floor and work area with drop cloths, and we handle the disposal of the old window and all debris.
