AfterGeometric & Shaped Windows in Miami, FL
Geometric and shaped windows in Miami typically run from $450 to $2,800 per unit installed, depending on the shape, size, glazing type, and whether the opening needs structural modification. Most residential jobs in Miami finish in a single visit once the custom unit arrives from the manufacturer. If you have an arched or curved window, circle, trapezoid, triangle, or any non-rectangular opening that needs replacing, retrofitting, or a fresh installation, call us at (561) 956-2754 – a live person answers every time, day or night.
TruePane Windows & Doors has been doing this work for over 42 years, and geometric windows represent some of the most exacting installs in residential glazing. A standard rectangular window sits in a plumb, square opening with predictable tolerances. A half-round above a Coral Gables entryway, or an octagon set into a Pinecrest foyer wall, requires field templates, tight manufacturer coordination, and an installer who genuinely understands how Miami’s humidity and wind-load requirements interact with non-standard framing. Our founder Dale Kessler built this company on the rule that if the pane is not true, the job is not done – and that rule matters more on a shaped window than almost anywhere else.
You can read about the full scope of what we offer under our Custom & Geometric Windows in Miami page, but this page focuses specifically on geometric and shaped units: what they cost, when you need one, how we handle the process, and what separates a careful install from one that leaks or fogs within two years of completion.
When You Need Geometric & Shaped Windows
- You have a fixed arch, half-round, or elliptical window that has started to fog between the panes. In Miami’s climate, the seal failure rate on these units is higher than on standard rectangles because the curved frame expands and contracts differently under South Florida’s heat cycles. Once the argon escapes and condensation forms inside the glass, the unit needs replacing – re-sealing from the exterior does not restore the insulating gap.
- Your home was built in the 1980s or early 1990s and the original builder-grade geometric windows were never upgraded to impact-rated glass. Coral Gables, South Miami, and parts of Coconut Grove have significant concentrations of this era’s construction. Many of those decorative arch and trapezoid windows were installed with single-pane or standard laminate glass that does not meet Miami-Dade’s current NOA (Notice of Acceptance) requirements for wind-borne debris protection.
- You are renovating and want a shaped window installed in an opening that currently has a rectangular unit – or no window at all. This is common in Brickell-area condos and Pinecrest single-family homes where architects specify an accent window to carry natural light into a stairwell or foyer. These openings require structural assessment before any glass goes in.
- Your shaped window leaks around the perimeter when it rains. Miami’s storm seasons put shaped windows under lateral wind pressure that rectangular units rarely see at the same intensity. A leak on a circle or triangle window almost always traces to the frame-to-wall interface or to a failed interior stop bead, not to the glass itself.
- A storm damaged the frame or glass on an existing shaped unit. After tropical weather events, we regularly see octagon and diamond windows in Kendall and South Miami where the frame has racked or the glass has cracked but the opening itself is structurally sound. In those cases, replacing just the unit is the right call.
- You want to add a statement window during a remodel and need guidance on what shapes, sizes, and glazing options are code-compliant in Miami-Dade County. Miami-Dade’s product approval process for non-standard windows is more involved than in most Florida counties, and the manufacturer’s NOA must match the specific shape and dimension of the unit being installed.
Our Geometric & Shaped Windows Process
- Field measurement and template verification. We do not rely solely on the dimensions written on a renovation plan or a builder’s original spec sheet. Every shaped opening gets measured directly using a physical template or a laser measurement tool, and we verify the rough opening is within tolerance before we order anything. For arched or elliptical openings, we check the spring point, the rise, and the chord width independently. A unit ordered to the wrong radius is a unit that ships back and adds six to eight weeks to your project.
- Manufacturer line selection and side-by-side quoting. TruePane is an authorized installer for more than a dozen manufacturer lines. For geometric windows in Miami, we most often work with PGT, CGI, and ES Windows for impact-rated shaped units – these three manufacture to Miami-Dade NOA standards in non-rectangular profiles. We put the options on paper side by side, with pricing, lead times, and warranty terms visible, so you are choosing with full information rather than taking our word for which line is best.
- Permit coordination where required. In Miami-Dade County, replacing a shaped window with an impact unit in an existing opening typically triggers a building permit if the unit is in an exterior wall. We handle the paperwork, submit the product approval documentation, and schedule the inspection. We do not hand that back to the homeowner and disappear.
- Removal and opening preparation. The existing unit comes out carefully. On older Coral Gables and Coconut Grove homes, shaped windows are often set in stucco surrounds that have been painted and caulked over multiple times. We cut the sealant perimeter clean, remove the unit without damaging the surrounding wall finish where possible, and inspect the rough opening for rot, moisture intrusion, or out-of-plumb framing before anything new goes in.
- Custom unit installation. The new unit is set, shimmed, and fastened to manufacturer specifications – not to whatever the last installer thought looked close enough. For impact-rated shaped windows, the anchor pattern and embedment depth are prescribed by the NOA, and we follow them precisely. Dale Kessler’s standard applies here as directly as on any other job: if the pane is not true, the job is not done.
- Warranty registration and walkthrough before we leave. Both manufacturer warranty layers – the glass unit and the frame finish – are registered in writing, with durations stated, before the truck leaves the driveway. That is The Keystone Standard, and it applies to every geometric window we install, not just the jobs where someone asks about it. We walk through what you have, how to clean it without voiding the coating warranty, and what the 90-Day Done Right Promise covers if anything needs a follow-up visit.
Geometric & Shaped Windows Pricing in Miami
Geometric and shaped window pricing in Miami varies more than almost any other window category because the glass, frame, and labor costs all scale with shape complexity. The table below reflects installed prices we see regularly in Miami-Dade County. These are honest ranges – not teaser figures that balloon at the invoice.
| Shape / Type | Typical Installed Range (Miami) | Notes |
|---|---|---|
| Half-round / arch (to 36″ wide) | $450 – $850 | Most common shaped window in Miami; impact-rated units add $200-$350 |
| Half-round / arch (37″ to 72″ wide) | $850 – $1,600 | Larger units common in Coral Gables entryways; lead time 4-8 weeks |
| Full circle / oval (standard sizes) | $700 – $1,400 | Pricing rises sharply if impact-rated in non-standard diameter |
| Triangle / trapezoid (fixed) | $550 – $1,200 | Common in stairwells and dormer openings; frame complexity drives the range |
| Octagon / diamond / specialty polygon | $900 – $2,200 | Multi-angle frames require precise field templates; do not order without physical measurement |
| Large feature arch (72″+ wide) | $1,600 – $2,800+ | May require structural lintel work; permit almost always required in Miami-Dade |
What moves the price up or down
- Impact vs. non-impact glazing. Miami-Dade’s wind-load requirements mean most exterior shaped windows need Miami-Dade product approval. Impact-rated units cost more up front but eliminate the need for storm shutters on those openings, which has real value in a South Florida home.
- Low-E coating and solar control glass. Miami’s solar heat gain is significant. A shaped window on a west-facing wall without proper low-E glass will run noticeably warmer and increase your cooling load. The upgrade is usually worth it.
- Rough opening condition. A well-preserved opening in a concrete block wall adds nothing. Rotted wood framing around an older Pinecrest home’s decorative arch can add $300-$600 in carpentry before the window goes in.
- Permit and inspection fees. Miami-Dade permit fees for window replacements are not fixed – they scale with the number of units and the job value. We include estimated permit costs in our written quote so you are not surprised at closeout.
Estimates are free and upfront. Call (561) 956-2754 and we’ll arrange a time to come out, take field measurements, and put a written number in front of you with no obligation. Seniors and veterans receive a permanent 5% discount on any job, and we take $50 off any repair over $250.
FAQs – Geometric & Shaped Windows
How long does it take to get a custom geometric window made and installed in Miami?
Most custom geometric windows have a lead time of four to eight weeks from order to delivery, and installation itself usually takes one to three hours per unit once the product is on site. The timeline varies by manufacturer – ES Windows and PGT, for example, carry Miami-Dade-approved shaped profiles in inventory for common arch sizes, which can reduce lead time. More complex shapes like octagons or large-radius ellipses almost always require full custom fabrication. We build the expected timeline into your written quote so there are no surprises mid-project. Call (561) 956-2754 for a specific estimate on your unit.
Do I need a permit to replace a shaped window in Miami?
In most cases, yes – Miami-Dade County requires a building permit when replacing an exterior window with an impact-rated custom window, and shaped windows are no exception. The permit process involves submitting the manufacturer’s Notice of Acceptance (NOA) for the specific product being installed, and the opening dimensions must match the approved product specifications exactly. TruePane handles permit coordination as part of the job. We have submitted dozens of these applications in Miami-Dade and understand the documentation the county requires. You do not have to navigate that office on your own. Call (561) 956-2754 and we’ll walk you through what your specific job will require.
Can a fogged geometric window be repaired, or does the whole unit need to come out?
A fogged geometric window – where you see condensation or haziness between the panes – cannot be meaningfully repaired by resealing the exterior perimeter. The fog means the sealed insulating unit (the glass assembly itself) has failed, and the argon or air gap that provides insulating value is gone. The glass unit needs to be replaced. In some cases, if the frame is in good condition, only the glass package comes out and a new insulated unit is set in the existing frame – this is called a glass-only replacement and costs less than a full frame-out. Whether that’s feasible depends on the frame condition and the manufacturer’s current production specs for that profile. We assess both options and give you the written price for each. Call (561) 956-2754 to schedule a look.
Are geometric windows more expensive to replace than standard rectangular windows?
Yes, geometric and shaped windows cost more per unit than comparable rectangular windows – typically 30 to 70 percent more, depending on the shape. The price difference comes from custom fabrication (fewer units of any given shape means higher per-unit manufacturing cost), longer lead times, and more labor-intensive installation that requires field templates, careful shimming at non-square angles, and tighter sealant work at curved or angled frame perimeters. That said, the labor gap is not enormous – the bigger driver is the glass and frame fabrication cost.

Why Miami Homeowners Choose TruePane for Geometric Windows
Dale Kessler has been in glazing since before some of our current competitors were incorporated. The geometric window jobs we see most often in Miami – half-rounds in Coral Gables, accent circles in Pinecrest, angled stairwell windows in Coconut Grove – require a level of field judgment that does not come from a franchise training manual. It comes from doing the work, getting it wrong once early in a career, and building every subsequent practice around not repeating that mistake.
When TruePane takes a geometric window job, the measurement happens twice, the manufacturer line gets selected based on what that specific shape requires for Miami-Dade product approval, and the warranty gets registered in writing before the crew packs up. The 90-Day Done Right Promise means that if anything about that install does not hold – frame movement, sealant failure, anything – we come back and address it without a paperwork argument. That is not a marketing line. It is what Dale Kessler put in writing from the first job and has not changed in over 42 years of serving this community.
