Trusted Custom & Geometric Windows for Port St. Lucie Homeowners
Custom and geometric windows in Port St. Lucie typically cost between $900 and $4,500 per opening, installed, depending on the shape, glass package, and whether impact-rated glazing is required. These are not stock units you pull off a shelf at a supply house. They are built to a template taken from your actual opening, and the difference between a good installation and a bad one shows up within two Florida summers. TruePane Windows & Doors has been setting custom glass in Port St. Lucie since 2008 of combined craft history under Dale Kessler, and we stand behind every opening with the Done Right Promise. Call (772) 362-3326 and a live person answers, day or night.
What Our Custom & Geometric Windows Service Includes
Custom Impact Windows
Custom impact windows are code-rated glazing built to match openings that standard impact units will not fit, whether because of an unusual rough opening, a historic facade, or a homeowner who wants a specific sightline. In Port St. Lucie, where the Florida Building Code governs impact requirements across much of the county, getting the product approval numbers right matters more than the glass itself. We measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves your driveway. If the pane is not true, the job is not done.

Geometric & Shaped Windows
Geometric windows include trapezoids, pentagons, hexagons, octagons, and clipped-corner units that give a room its architectural character. These shapes require exact templates because a quarter-inch error at the frame means a window that will not seat and a seal that will not hold. TruePane orders every geometric unit from the manufacturer’s custom shop using a physical template, not a napkin sketch, and confirms the frame dimensions against that template before the order is released. We have set hundreds of shaped openings across Port St. Lucie, and we know which manufacturers will build a true radius and which ones will not.

Arched & Curved Windows
Arched and curved windows are the most demanding of all custom glasswork because a curve magnifies any error in the rough opening. A true radius arch has a consistent curve from spring line to peak; an out-of-round arch binds on one side and leaves a gap on the other. We check the opening with a radius template before ordering, then set the unit with shims placed to carry the load evenly around the curve. Dale Kessler learned curve work the hard way, on jobs where the builder said the arch was “close enough” and the window proved otherwise. We do not accept close enough.

Oversized Openings
Oversized openings are any window span that exceeds standard manufacturer sizing, typically over 36 square feet of glass or any single dimension beyond 72 inches. These units weigh more, flex more, and require header verification and often a heavier frame system to carry wind load. TruePane inspects the header and king studs before ordering an oversized unit, and we will tell you plainly if the structure needs reinforcement before glass goes in. In Port St. Lucie’s coastal wind zone, an oversized opening that has not been properly framed is a future service call waiting for the next storm.

Brands We Service for Custom & Geometric Windows
TruePane is an authorized installer for PGT and CGI custom lines, which means we order directly from the factory and both warranty layers get registered in writing before we leave the driveway. We have built PGT WinGuard and CGI Sentinel units into trapezoids, arches, and oversized gables across Port St. Lucie, and we know the lead times on custom shapes as well as anyone in the county. PGT’s custom shop handles most non-standard shapes well, but the order details have to be exact the first time, because a rebuilt unit costs a homeowner six to eight weeks. We do not let that happen.
We also work with Andersen, Pella, Marvin, Milgard, Jeld-Wen, and ES Windows on custom geometric work, and we quote manufacturer lines side by side on paper so you can see exactly what you are paying for and what each warranty actually covers. Some manufacturers will not touch certain curves or clip angles; we will tell you that before you commit. Whether you have PGT, CGI, or any other make in your opening, we can service it and set a new one true.
Signs You Need Custom & Geometric Windows Right Now
- Visible seal failure between the panes. Fog, condensation between glass layers, or a milky haze means the inert gas has escaped and the insulating value is gone. In a custom shape, resealing is rarely cost-effective compared with a rebuilt unit, especially in a Port St. Lucie home where humidity pushes the failure faster.
- Daylight around the frame. If you can see sunlight around the sash or frame of a geometric window, the unit has shifted or the original installer shimmed it wrong from day one. That gap is an air leak, a water path, and an insect entry, and it will not fix itself.
- The window will not open or close without a fight. A shaped window that binds when you try to operate it is telling you the frame racked after installation. In an arched or round-top unit, binding almost always traces back to improper shim placement or a rough opening that was never squared.
- Water stains on the drywall below the window. Staining under a geometric window usually means the pan flashing was omitted or incorrectly lapped during the original install. Port St. Lucie gets afternoon thunderstorms that find those mistakes, and by the time you see the stain, the sheathing behind the drywall has been wet for a while.
- The window is original to a home built before 1995. Pre-1995 custom windows in Port St. Lucie were almost never impact-rated and may not meet current wind load requirements for this zone. If you are in a home that old with original shaped glass, the glass is the least of what needs to change to bring the opening up to code.
Our Custom & Geometric Windows Process - Step by Step
- 1
Measure and template the opening. Our technician arrives uniformed and background-checked, then measures every opening twice, checks for square and plumb, and builds a physical template for any shape that is not a simple rectangle. This template goes to the manufacturer exactly as cut. No estimating from memory, no rough numbers.
- 2
Quote the options on paper. You get manufacturer lines side by side with frame material, glass package, impact rating, and price for each, written out line by line. We do not give verbal ballparks on geometric work because the math is too important. A square deal means you see every number before you sign.
- 3
Order with the template attached. We place the factory order with your approved spec and attach the physical template to the purchase order. Our project manager confirms lead time and schedules your install based on the manufacturer’s confirmed date, and we will be there when we say.
- 4
Prep and verify the rough opening. Before the new unit arrives, we inspect the header, the king studs, and the sill for rot, racking, or any structural compromise. If the opening needs carpentry, we do it now or tell you plainly and pause the order. No one ever got a true window from a crooked hole.
- 5
Set, seal, flash, and register. We set the unit with shims placed to carry the load evenly, seal the perimeter per the manufacturer’s spec, flash the pan and head correctly for a Port St. Lucie climate, and register both warranty layers in writing before we leave. Then we walk the job with you and show you what was installed and why.
- 6
Ninety days of Done Right. If anything about the install is not right within 90 days, we make it right. No paperwork fight, no arguing. The Keystone Standard is the whole reason this company exists.
How Much Does Custom & Geometric Windows Cost in Port St. Lucie?
A single trapezoid or octagon fixed window in Port St. Lucie typically runs $900 to $2,200 installed, depending on the glass package and whether you need laminated impact glass. An arched top or true radius window usually lands between $1,800 and $3,800 because of the template work and the curve-specific factory charge. An oversized gable or picture window pair can run $3,500 to $7,500 or more when you factor in structural reinforcement and a heavier frame system rated for the wind zone. The table below gives line-item ranges for common scenarios.
- Fixed geometric window (trapezoid, pentagon, octagon): $900-$2,200 installed
- Arched or radius top window: $1,800-$3,800 installed
- Oversized opening (36+ square feet of glass): $3,500-$7,500+ installed
- Impact-rated upgrade on any custom shape: add 40-60% to the base unit price
- Structural carpentry for a racked or undersized header in an older home: $400-$1,800 depending on scope
What moves the price most is the glass. A standard insulated low-E unit costs far less than a laminated impact unit built to Miami-Dade or Florida Building Code standards, and custom shapes carry a factory upcharge that varies by manufacturer. The way to avoid overpaying is to get the quote in writing with the glass package, impact rating, and warranty terms named, not summarized. Our free estimate includes all of it, side by side on paper, and the price we quote is the price you pay. No change orders, no surprise line items on the bill. Call (772) 362-3326 to schedule yours.

Frequently Asked Questions - Custom & Geometric Windows in Port St. Lucie
A custom or geometric window is any opening that deviates from a standard rectangle: arches, circles, trapezoids, pentagons, octagons, clipped corners, or unusual sizing. These units are built to a template taken from your specific opening, not pulled from stock. That template is what determines whether the window fits true or fights you from day one.
Most custom geometric window replacements are completed in a single visit once the unit arrives from the factory. The typical lead time for a custom shape from PGT or CGI is four to eight weeks from order confirmation. We schedule the install for a specific day and we will be there when we say.
Expect $900 to $4,500 per opening for most geometric shapes, with oversized or impact-rated units running higher depending on the opening and the code requirements in your specific zone. The glass package is the biggest variable, followed by any structural work the existing framing needs. Call (772) 362-3326 for an exact quote, and our estimates are always free.
Yes. TruePane is an authorized installer for both PGT and CGI custom lines, and we order directly from the factory with your template attached. We also work with Andersen, Pella, Marvin, Milgard, Jeld-Wen, and ES Windows, and we register both warranty layers in writing on every job.
For a cracked pane or a blown seal in a geometric window, we can secure and measure the opening on the first visit, then order the correct replacement unit. Because custom shapes are built to template, the replacement cannot be pulled from a service van the same day. We will install a temporary weatherproof covering if needed and get the permanent unit ordered the same week.
Yes, and this is the point of The Keystone Standard. We register both warranty layers, the glass and the installation, in writing before we leave your driveway. You get a copy with the durations stated, and the Done Right Promise covers our workmanship. If it is not done right, we make it right, no arguing.
Clear the interior area around the window by about six feet so our technicians can work safely, and move anything fragile off nearby shelves. We cover the work area, protect the floors, and clean up when we finish, but clearing the space beforehand saves time. Our team works in your home the way they would work in their own mother’s home.
