AfterTrusted Custom & Geometric Windows for Miami Homeowners
Custom and geometric windows in Miami cost between $1,800 and $8,500 per opening installed, depending on the shape, impact rating, and framing. We measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves your driveway. Most custom window projects take 3 to 6 weeks from order to install, because the glass is cut to your exact opening in the factory, not on site.
TruePane Windows & Doors has served Miami homeowners for over 42 years through a craft lineage that started with Dale Kessler, a second-generation glazier who founded the company in 2008 on a simple rule: if the pane is not true, the job is not done. We handle arched transoms in Coral Gables, octagonal picture windows in Kendall, radius corner units in Palmetto Bay, and oversized impact-rated openings facing Biscayne Bay. A live person answers when you call (561) 956-2754, any hour, any day.
What Our Custom & Geometric Windows Service Includes
Every custom window starts with the opening, not the other way around. We build to your framing, your sightlines, and the wind load requirements of your specific Miami neighborhood. Here is exactly what falls under our custom and geometric window work.
Custom Impact Windows
Custom impact windows in Miami are not an option on waterfront property or in any home inside the high-velocity hurricane zone. A standard rectangle will not always fit a mid-century modern facade or a 1920s Coral Gables Spanish revival. We build impact-rated glass into custom frame shapes, using laminated glass that meets Miami-Dade County product approval, so your custom window holds its geometry and its protection under storm load. TruePane orders each unit to the exact opening dimensions, including depth, and we pull permits where code requires them.
Geometric & Shaped Windows
Geometric windows include trapezoids, octagons, pentagons, parallelograms, and any shape that is not a standard rectangle or square. Miami homes built in the 1980s and 1990s used these heavily in entryways and stairwells, and many of those original frames are now failing. We template the opening, order the glass cut to within an eighth of an inch, and set the unit so the reveal is even on every side. No one in the trades calls a trapezoid “a weird window” and means it as a compliment, but that is our bread and butter.
Arched & Curved Windows
Arched windows carry the weight of the frame differently than rectangular units, because the curve concentrates load at the springline. A poor install leaves the arch out of round, the sash binding, and the seal failing along the radius. TruePane measures the arc, matches the frame curve to the manufacturer’s specification, and installs with shims placed so the arch stays true after the trim is on. We do true radius, eyebrow, and half-round units over doors, in gable ends, and in the tower rooms common to older Miami architecture.
Oversized Openings
Oversized openings in Miami need two things most window installers underestimate: structural framing at the header and glass thick enough to carry hurricane wind pressure across a large span. A 10-foot-wide opening facing east toward the water takes a beating the setback houses in Kendall never see. We spec the unit with the correct laminated glass thickness, reinforce the rough opening where needed, and use a setting team that handles the weight without twisting the frame. Every oversized unit we install gets the same 90-Day Done Right Promise in writing, no matter how long the engineering review takes.

Brands We Service for Custom & Geometric Windows
We are an authorized installer for more than a dozen manufacturer lines, and custom shapes narrow that list to the makers who actually build them correctly. PGT is the brand we spec most often for custom impact windows in Miami, because their custom shape program covers more geometry than most and their laminated glass carries Miami-Dade approval without drama at inspection. We have installed PGT custom units in waterfront homes from North Miami to Cutler Bay, and we order their frames with the exact reveal and depth the opening demands.
CGI builds a stiffer frame than most, which matters on oversized custom openings where racking under wind load is the failure mode. We recommend CGI when the homeowner wants aluminum frames painted to match a specific trim color, and when the opening is wide enough that deflection limits matter. CWS is our go-to when the architect specifies a custom timber-clad or thermally broken aluminum system, and we quote CWS side by side with PGT and CGI on paper so the homeowner sees the price difference in writing, before any deposit changes hands. Whether you have PGT, CGI, CWS, or any other make, we can quote, order, and install it.
Signs You Need Custom & Geometric Windows Right Now
- Fog between the panes on a shaped window. The seal on a trapezoid or arch fails the same way as on a rectangle, but the replacement is specialized. Once the seal is gone, the only permanent fix is a new insulated glass unit cut to the same custom shape, and that is an order, not a patch. The longer fog sits in the glass, the more the frame sweats and stains the surrounding drywall.
- Water staining below an arched or radius window after heavy Miami rain. A leak on a curved window usually means the flashing at the springline was never lapped correctly, or the frame has shifted out of round. Miami’s afternoon storms find every incomplete seal. If the drywall below the arch shows tide lines after a storm, the window is letting water into the wall cavity, and mold follows in this humidity.
- The sash binds when you open it, and it binds worse in summer. Miami’s heat and moisture make wood and vinyl move, and a custom window that was out of square from day one will bind as the frame swells. A rectangle can hide a half-inch of slop; a hexagon cannot. If you have to shoulder the window open, the frame is racked and will only get worse.
- Your oversized picture window flexes when the wind gusts. You can see it if you watch the glass during a storm band: the pane bows visibly, and the reflection waves. That is a sign the glass is under-specified for the opening, and under hurricane wind load it can pop the seal or crack. Miami wind speeds against a large custom pane are no place for builder-grade glass.
- You are planning a remodel, and the existing windows do not match the architect’s drawings. The time to spec custom windows is before the drywall goes up, not after. Changing a rough opening later costs framing money and delays the job. We will template the openings as soon as the framing is in, so the window order lands before the finish work starts.
Our Custom & Geometric Windows Process - Step by Step
- 1
Measure and template. Every opening gets measured twice, by two people, and for any shape beyond a simple rectangle we cut a physical template from plywood or corrugated board. That template goes to the manufacturer with the order, so the glass is cut to the actual opening, not to a set of handwritten numbers. Dale Kessler’s rule applies here first: if the measurement is not true, nothing downstream is.
- 2
Quote side by side on paper. We show you the manufacturer lines we recommend, the glass package, the frame material, and the price for each option in writing. You see what PGT charges versus CGI for the same shape, what the impact rating adds, and what the install labor runs. No verbal estimates, no “we’ll figure out the price later.”
- 3
Order and register warranties. Before the truck leaves the driveway on install day, both manufacturer warranty layers are registered in writing, with durations stated, under The Keystone Standard. That means the glass warranty and the frame warranty and the install workmanship are all documented, not promised in a handshake. If the manufacturer’s registration ever gets challenged, we have the paper.
- 4
Install with shims set for the shape. A geometric window gets shimmed differently than a rectangle, because the load paths are different. Our uniformed, background-checked technicians set each unit level and true, with shims at the load points the shape actually needs: the vertices of a hexagon, the springline of an arch, the center of a long span. We do not foam-and-go.
- 5
Walk the job and sign off. You watch us open and close the window, check the reveal on every side, and verify the locking points. If anything is not done right, we fix it then or schedule the correction immediately, under the 90-Day Done Right Promise. No paperwork fights, no arguing.
How Much Does Custom & Geometric Windows Cost in Miami?
A custom arch or half-round in Miami typically runs $1,800 to $3,900 installed for a fixed, non-operable unit in vinyl or aluminum. A custom geometric window with an impact rating, like a trapezoid or octagon, runs $2,600 to $5,500 per opening, depending on the glass package and whether the frame is thermally broken. A truly oversized custom opening, something in the 8-foot to 12-foot range with Miami-Dade impact glass, runs $4,500 to $8,500 or more, and the engineering review adds time before the order goes in.
Three things move the price: the shape complexity, the impact rating, and the frame material. A radius window costs more than a straight-sided polygon because the glass bending and frame fabrication require different tooling. Impact glass adds roughly 30 to 50 percent to the unit cost over non-impact, but it is required in most of coastal Miami and frankly is the right call even where code allows otherwise. Aluminum frames cost more than vinyl up front but hold paint and stay true longer in Miami’s salt air. Any quote you get should include the template, the unit, the install, the flashing, and the haul-away of the old window, all in one line-item total. That is how we write ours, and it is why our customers never see surprise charges on the final bill.

Frequently Asked Questions - Custom & Geometric Windows in Miami
A custom or geometric window is any window that is not a standard rectangular unit: arches, half-rounds, eyebrow windows, trapezoids, octagons, pentagons, and oversized openings. Most are ordered to exact opening dimensions rather than pulled from a warehouse inventory. Miami builders from the 1980s through the early 2000s used geometric windows heavily in entryways and gable ends, so replacements are common across the county.
From measure to finished install, most custom and geometric window projects take 3 to 6 weeks. The majority of that time is manufacturer lead time, because the glass and frame are fabricated to your specific shape and impact rating. The on-site installation itself typically takes one to two days per opening, depending on the size and whether structural framing at the header needs reinforcement. Call (561) 956-2754 for a schedule based on your project.
Expect $1,800 to $8,500 per opening installed, with the spread driven by shape complexity, impact rating, and frame material. A simple fixed arch costs less than an operable octagon with impact glass. We quote manufacturer lines side by side on paper so you see the exact price before committing a dollar. Estimates are free, and the price we quote is the price you pay.
We do, and PGT is the brand we spec most often for custom impact shapes in Miami. As an authorized installer, we order directly from PGT with a physical template from your opening, register both warranty layers before install day, and handle the paperwork if a warranty claim ever comes up. The same applies to CGI and CWS custom lines.
A broken custom window after a storm needs boarding or temporary glazing quickly, and a live person answers our phone 24 hours a day, 7 days a week to get that moving. The permanent replacement still needs templating and a manufacturer order, but securing the opening is not something that waits until business hours. Call (561) 956-2754 and a person picks up, every time.
Every TruePane job carries The Keystone Standard: both manufacturer warranty layers, glass and frame, registered in writing with durations stated, before the truck leaves the driveway. On top of that, our workmanship is guaranteed under the 90-Day Done Right Promise. If it is not done right, we make it right, with no paperwork fights and no fine print. For exact coverage on your window, ask us on the phone.
Clear a working path inside and outside the opening, move furniture back roughly six feet from the window, and take down window treatments before we arrive. Our technicians protect the floor and clean the work area when the install is done. If the window is oversized or on an upper floor, let us know in advance so we can bring the right lifting equipment.
