AfterTrusted Custom & Geometric Windows for Miami Homeowners
Custom and geometric windows in Miami cost more than standard rectangular units because every pane, frame, and radius must be engineered to handle hurricane-force wind loads while matching an architect’s exact drawing. Ed Winslow has been installing these windows across South Florida since 2011, and his crews have handled everything from 12-foot arched picture windows in Coral Gables to trapezoid impact units in Miami Beach high-rises. When you call (863) 946-5039, you reach a live person who can talk through your project the same day.
Wind-driven rain finds every gap. Geometric windows fail at the corners first, where stress concentrates during storms. We’ll check the existing framing, the sealant joints, the glazing, and the anchorage before recommending repair or full replacement.
What Our Custom & Geometric Windows Service Includes
Every custom window job starts with measurements, not guesses. We field-verify the rough opening in three dimensions, check for racking or settling, and then match your new window to the actual conditions of your Miami home.
Custom Impact Windows
Custom impact windows are laminated-glass units built to meet Miami-Dade County’s strict wind and debris standards for the High Velocity Hurricane Zone. You need these when your home sits in a flood zone, faces open water, or when your current windows predate the 2002 Florida Building Code updates. Ed’s team orders every custom impact unit from our authorized manufacturing partners, verifies the product approval numbers against your specific opening size, and installs to code with the paperwork to prove it.
Geometric & Shaped Windows
Geometric windows include triangles, trapezoids, pentagons, circles, half-circles, and any other shape that is not a standard rectangle. Miami homeowners typically need these for gable ends, stairwells, and architectural accents where a standard window simply will not fit the framing. We template every opening before ordering, which means the glass arrives cut to the exact degree of your header angle, not force-fit into an approximation.
Arched & Curved Windows
Arched windows use a curved top section that can be a true half-circle, a shallow eyebrow, or a custom radius. They’re common in Mediterranean Revival homes across Coral Gables and in newer construction where builders want a softer daylight profile. Winslow Windows & Doors fabricates these through our authorized brands when possible and custom-cuts the flanges and buck frames when your opening is not a standard radius.
Oversized Openings
Oversized openings span more than 48 inches in any dimension and require heavier glass, stronger frames, and more careful installation to prevent sagging and water intrusion. You’ll see these on waterfront homes in Aventura and Palmetto Bay where panoramic views are the whole point of the window. We size the structural mullions, specify the correct laminated glass thickness for your elevation, and set the unit so it stays square for decades, not seasons.

Brands We Service for Custom & Geometric Windows
We are an authorized installer for PGT and CGI, the two dominant impact-window manufacturers in Florida. PGT’s WinGuard and ImpactGard lines are our most-installed products for custom geometric work because PGT engineers each unit to Miami-Dade product approval standards. CGI brings the commercial-grade aluminum frames we use on larger arched and trapezoid units where steel reinforcement matters. Our installers have set hundreds of PGT and CGI openings across Miami-Dade and know each brand’s anchoring requirements without a second thought.
ViewLux rounds out the custom geometric lineup when a client wants a sleeker, narrower frame profile for a contemporary design. ViewLux units work well in modern Doral townhomes and new construction in Kendall where architects spec clean sightlines. Whether you have PGT, CGI, ViewLux, CWS, or any other make installed, we service it and we can replace it when the time comes.
Signs You Need Custom & Geometric Windows Right Now
- Daylight visible around the frame. If you can see a sliver of sky between the window frame and your stucco or drywall, the anchorage or sealant has failed. In Miami, that gap is a water and wind intake point, and it will get worse with every storm front that rolls through.
- Condensation between the glass panes. Laminated impact glass is sealed at the factory. Fogging between panes means the seal has broken, and the window has lost its insulating gas fill. You’re now paying to cool air that leaks straight through the glass.
- Visible cracks radiating from a corner. Geometric windows concentrate stress at sharp angles. A crack starting at a corner of your triangle or trapezoid unit means the glass is failing, and once it goes, the whole pane loses its impact rating.
- Water stains on the interior sill or wall. Staining below an arched or shaped window tells you water is entering somewhere and traveling downward. By the time you see the stain, the leak is not new, and the framing behind the wall is likely wet at minimum.
- Difficulty opening or closing the window. Custom geometric windows are often fixed, but any operable unit that sticks, scrapes, or won’t seal is telling you the frame has shifted. In a hurricane, a window that doesn’t seal is a window that allows pressurization of your home.
Our Custom & Geometric Windows Process - Step by Step
- 1
Free on-site evaluation. Ed or one of his senior installers visits your Miami home to measure the rough opening, assess the existing framing, and identify any water damage or structural issues. Our team uses laser measuring tools for precision, not a hand-drawn tape sketch. We document everything with photos so you can see what we see.
- 2
Detailed estimate with product approval numbers. We give you a written line-item quote that names the brand, the exact glass assembly, the Miami-Dade product approval number for your specific opening size, and the installed price. There are no allowances, no vague “TBD” lines, and no change orders later because we did the homework up front.
- 3
Permit application and engineering. We pull the permit and, when your opening requires it, coordinate the structural engineering for the header, buck frame, or added anchorage. Miami-Dade municipalities inspect every custom impact installation, and we schedule the inspection and meet the inspector on site.
- 4
Installation day. Our background-checked technicians arrive in uniform, protect your floors and furniture, remove the old window, repair any framing rot we find, and set the new custom unit. We seal the perimeter with commercial-grade flashing and sealant rated for South Florida’s heat and rain cycles.
- 5
Final walkthrough and inspection closeout. After the install, we walk the opening with you, review the final sealant lines, and leave you with your warranty documents, product approvals, and the inspection sign-off. Ed stays reachable after the job closes, because the 36500-Day Done Right Promise doesn’t end when the crew pulls away.
How Much Does Custom & Geometric Windows Cost in Miami?
Several factors move the number. Glass thickness and type are the largest line items. Miami-Dade product approval adds engineering cost on any opening larger than 55 square feet. The condition of your existing framing matters, too - if we find rot behind the old window, the repair work adds time and materials. But here’s the part that matters: your estimate is fixed once we measure. No change orders, no “we didn’t expect that.” Every estimate we provide is built from measured openings and published material pricing. Call (863) 946-5039 to schedule your evaluation, and you’ll receive a free written quote with no obligation. While we’re there, ask about our free second opinion offer - if you have another written estimate, we’ll review it and tell you honestly whether you’re getting a fair deal.

Frequently Asked Questions - Custom & Geometric Windows in Miami
What are custom and geometric windows?
Custom and geometric windows are any window units that are not standard rectangular sizes or shapes. They include arches, circles, triangles, trapezoids, and oversized fixed panes built to match a specific architectural opening in your home. In Miami, most custom geometric windows are also impact-rated because Miami-Dade County code requires impact protection on nearly all residential openings.
How long does custom window installation take?
Most custom and geometric window installations are completed in one to two business days per opening. The larger variable is the lead time to fabricate the custom unit, which typically runs three to six weeks from the day we finalize measurements. We’ll give you a written production schedule when we deliver your estimate so you know exactly when to expect installation.
How much does a custom geometric window cost in Miami?
A custom geometric impact window in Miami typically runs $2,800 to $7,500 per unit installed, with oversized and water-facing openings at the higher end. The exact price depends on the glass assembly, frame material, opening size, and any structural repair we uncover during the pre-installation inspection. Call (863) 946-5039 and we’ll give you a free exact quote with no obligation.
Do you service PGT custom windows?
Yes, we’re an authorized PGT installer and we service PGT custom and geometric windows across Miami. We can order replacement PGT units, verify your existing product approvals, and install or repair the window to maintain your home’s hurricane protection. The same applies to CGI, ViewLux, and CWS units.
Is emergency replacement available for broken custom windows?
If you have a broken custom or geometric window and need it secured immediately, call us any time - a live person answers 24/7 at (863) 946-5039. We’ll send a technician to secure the opening safely and begin the replacement process. We know a broken impact window in Miami is an urgent security problem, especially during storm season.
Do custom windows come with a warranty?
Every custom and geometric window we install carries the manufacturer’s warranty on the glass and frame, plus our 36500-Day Done Right Promise. If the work is not done right, Ed Winslow makes it right, period. That’s a promise backed by a published address, a license number, and a real person in Miami.
How do I prepare for a custom window installation?
Clear the interior and exterior areas around the window by about six feet, move furniture and wall hangings, and make sure the crew has access to electricity. We handle floor protection and cleanup as part of the job. We’ll also let you know in advance if the existing opening requires more extensive framing work once we get the old window out.
