AfterCustom Impact Windows in Miami, FL
Custom impact windows in Miami are hurricane-rated glazing units built to non-standard dimensions, shapes, or configurations that standard off-the-shelf impact products cannot fill, which is why our Custom & Geometric Windows services are often the right fit. They protect your home against Category 5 wind loads and windborne debris while meeting Miami-Dade County’s Notice of Acceptance (NOA) requirements – a code standard that is stricter than anywhere else in the continental United States. At TruePane Windows & Doors, Dale Kessler and our crew have been setting these units into Miami-area homes for decades, and every job is governed by the same founding rule: if the pane is not true, the job is not done.
If you have a round porthole in a Coral Gables bungalow, an angled clerestory in a Pinecrest ranch, or a wide picture opening in a Palmetto Bay waterfront home that no catalog unit will fit, you are already in custom-impact territory. Call us at (561) 489-4036 – a live person picks up around the clock, seven days a week – and we will walk through the scope with you before you commit to anything. Our Custom & Geometric Windows in Miami service covers the full range of non-standard shapes and configurations; this page focuses specifically on impact-rated glazing within that category.
TruePane is an authorized installer for more than a dozen manufacturer lines, including PGT, CGI, and ES Windows – three manufacturers whose impact product catalogs run deepest in the South Florida market. We quote those lines side by side on paper so you can see exactly what you are buying before you sign anything.
When You Need Custom Impact Windows
Not every opening in Miami requires a custom-fabricated impact unit, but the situations below almost always do. If any of these sounds familiar, a templated off-the-shelf product will not get you to code – or to a satisfied insurance underwriter.
- Non-standard rough opening dimensions. Older Miami homes – particularly pre-1980 CBS construction in areas like Little Havana, Hialeah, and the Roads neighborhood – were built to dimensions that do not match any current standard window size. A custom impact unit is the only way to fill those openings properly and pass a Miami-Dade building inspection.
- Geometric or architectural shapes. Arched, circular, triangular, trapezoidal, or raked frames require custom fabrication from the start. Impact glazing in these shapes must still carry a Miami-Dade NOA – a requirement that eliminates most decorative-only suppliers.
- Insurance or permit compliance after a remodel. If a renovation changed your wall framing or you are refinancing and your insurer is asking for impact-rated opening protection, every window must carry documentation. Custom units built to your current opening dimensions are often the cleaner path than trying to fur-out or infill to match a catalog size.
- Historic or deed-restricted properties. Coral Gables, Coconut Grove historic districts, and many HOA-governed communities in South Miami-Dade require that replacement windows match the original profile, grid pattern, or finish. Custom impact fabrication lets you hit both the aesthetic and the wind-load requirement without a variance battle.
- Existing impact frames with failed glazing. When an impact frame itself is structurally sound but the glass has fogged, cracked, or delaminated – a common occurrence with units more than fifteen years old in Miami’s salt-air environment – a custom-cut impact glass replacement can preserve the frame and avoid a full-unit change-out.
- New construction or addition with odd bay spacing. Room additions in Miami’s tight lots often produce openings that were sized around structural constraints, not window catalogs. Custom impact units designed to the actual rough opening are the right starting point, not the compromise.
Our Custom Impact Windows Process
This is how a TruePane custom impact window job moves from your first call to a registered warranty. No steps are skipped, no templating, no guessing at field measurements.
-
Initial consultation and site assessment.
A uniformed, background-checked TruePane technician visits your home – on time, prepared – and walks every opening with you. We look at the rough opening dimensions, the wall thickness, the existing frame condition, the exterior finish, and any HOA or historic-district constraints. This is where we flag anything that will affect fabrication lead time or permitting before it becomes a surprise on the back end. -
Precision field templating.
We measure every opening twice. For geometric shapes, we use physical templates cut on site rather than relying on nominal dimensions. Miami’s older housing stock has enough settling and out-of-square framing that a quarter-inch error in a template produces a unit that will not seat properly – and a unit that does not seat properly does not pass a Miami-Dade inspection. -
Manufacturer line comparison and written quote.
We pull specifications from the lines best suited to your opening – typically PGT, CGI, or ES Windows for South Florida custom impact work – and present them side by side on paper. You see the glass package, the frame material, the Miami-Dade NOA number, and the warranty duration for each option. No verbal promises, no vague “impact-rated” language. Upfront pricing, no surprise line items when the bill arrives. -
Permit submission and NOA documentation.
Custom impact windows in Miami require a building permit and must reference a valid Miami-Dade NOA. TruePane handles the permit application; we do not hand that to you to figure out. Miami-Dade’s product approval database is updated regularly, and using an expired or inapplicable NOA is the fastest way to fail an inspection. We know which NOAs apply to which products and which installation configurations. -
Installation – measured, set, sealed, and inspected.
The unit arrives fabricated to our field template. We set it into the opening, check level and plumb in multiple planes, apply the required Miami-Dade-approved anchoring, and apply the exterior seal. Impact frames in Miami’s climate need a specific weatherseal sequence – salt air and UV degradation will work into any gap the first hurricane season gives them. After installation, we schedule the required inspection and stay with the job until it passes. -
Warranty registration before the truck leaves.
This is The Keystone Standard: both manufacturer warranty layers – product and glass – are registered in writing, with durations stated, before we leave your driveway. You hold the paperwork. If something is wrong within 90 days of completion, our Done Right Promise covers it with no arguing and no fine print review. Done right the first time is the standard; the 90-day promise is the backup.
Custom Impact Windows Pricing in Miami
Custom impact windows in Miami typically run between $850 and $2,800 per unit installed, depending on size, shape complexity, glass package, and frame material. That range is wider than standard-size impact windows because fabrication cost scales with complexity in ways that off-the-shelf products do not. The table below gives honest market ranges for the configurations we see most often in Miami-Dade County.
| Configuration | Typical Installed Range (Miami) |
|---|---|
| Custom-size rectangular casement or single-hung (non-standard dimension) | $850 – $1,400 per unit |
| Custom-size picture or fixed unit, up to 48″ x 72″ | $1,100 – $1,800 per unit |
| Arch-top or radius-corner custom impact unit | $1,400 – $2,200 per unit |
| True geometric shape (circle, triangle, trapezoid) | $1,600 – $2,800 per unit |
| Oversized picture unit (above 48″ x 72″) | $1,800 – $2,800+ per unit |
Several factors push a specific job toward the high or low end of those ranges:
- Glass package. Laminated impact glass with a low-E coating and argon fill costs more than standard laminated clear, but the long-term savings on a Miami FPL bill – and the comfort difference in a west-facing bedroom in August – are real. We show you the payback math on paper.
- Frame material. Aluminum frames are the Miami standard for impact work because they handle humidity and salt air better than vinyl over the long run. Fiberglass-framed impact units carry a price premium but deliver the best thermal performance, which matters in Miami’s climate even when the storm shutter mentality dominates the conversation.
- Shape complexity. A non-standard rectangle is a straightforward custom cut. A true ellipse or an arched transom with a matching sidelite requires more fabrication time and more precise templating. We tell you what drives the number, not just what the number is.
- Permit and inspection fees. Miami-Dade County permit fees for window replacements vary by project valuation. We include the permit cost in our written quote so it does not appear as a line-item surprise when the job closes.
- Removal and disposal of existing units. Removing an old aluminum jalousie or a single-pane fixed unit from a 1960s Coconut Grove home is a different job than pulling a newer vinyl frame. We assess removal scope during the site visit and price it honestly upfront.

FAQs – Custom Impact Windows in Miami
Do custom impact windows in Miami still need a building permit?
Yes – every window replacement in Miami-Dade County, including custom impact units, requires a building permit and must reference a valid Miami-Dade Notice of Acceptance. There is no exemption for custom-fabricated units, and there is no exemption for smaller openings. TruePane handles permit submission for every job; we do not pass that step to the homeowner. An unpermitted impact window can void your homeowner’s insurance coverage and create a title problem when you sell. If a contractor quotes you a custom impact job without mentioning a permit, that is the first question to press them on.
How long does a custom impact window order take in Miami?
Custom-fabricated impact units built to non-standard dimensions or geometric shapes typically carry a lead time of four to eight weeks from the date your order is placed with the manufacturer, depending on the product line and the complexity of the shape. ES Windows, PGT, and CGI all maintain South Florida fabrication or distribution capacity, which keeps lead times closer to the four-week end for most rectangular custom sizes. True Geometric & Shaped Windows – circles, trapezoids, compound curves – run longer. We give you a written lead-time estimate at the time of the quote, and we do not pad it to manage expectations after the fact.
Will custom impact windows lower my homeowner’s insurance in Miami?
In most cases, yes. Florida’s insurance market gives significant premium credits for homes with full opening protection meeting Miami-Dade wind-load standards. The credit applies when all openings – windows and doors – are protected. A single unprotected opening on an otherwise impact-protected home can disqualify you from the full credit. The actual credit percentage is set by your insurer and your policy terms; we do not quote insurance numbers because every policy is different. What we can tell you is that custom impact windows built to a valid Miami-Dade NOA count toward that protection, and we provide the documentation your insurer will ask for. Call (561) 489-4036 and we can walk through what documentation you need before you contact your carrier.
Can TruePane match the original look of my historic or HOA-restricted home in Miami?
Yes – this is one of the more common reasons homeowners in Coral Gables, Coconut Grove, and South Miami reach out to us specifically. Custom fabrication means we are not limited to catalog profiles, grid patterns, or standard finishes, and we can accommodate Arched & Curved Windows when your design calls for them. We work with manufacturer lines that offer historically appropriate sightlines and can match bronze, white, dark bronze, or custom-color powder-coat finishes to meet HOA or historic district requirements. The key is getting the district’s written design criteria before fabrication begins, which we build into our site-assessment step. A custom impact unit that passes both the Miami-Dade NOA requirement and a historic review board is a more involved quote, but it is a square deal – you know exactly what you are getting and why it costs what it costs.

- Custom impact windows are required any time a non-standard opening dimension, geometric shape, or historic-profile requirement rules out catalog products – and they still must carry a Miami-Dade NOA to pass inspection.
- Installed pricing in Miami typically runs $850 to $2,800 per unit, depending on shape complexity, glass package, and frame material.
- TruePane handles the permit from submission to inspection sign-off – homeowners do not navigate Miami-Dade’s product approval database on their own.
- Every job is covered by the 90-Day Done Right Promise and The Keystone Standard: both warranty layers registered in writing before the truck leaves your driveway.
- Dale Kessler’s crew measures every opening twice and templates geometric shapes on site – a step that prevents the most common failure point in custom impact installs.
- Seniors and veterans receive a permanent 5% discount on every qualifying job; repairs over $250 are eligible for $50 off.
