AfterTrusted Custom & Geometric Windows for Miami Homeowners
Custom and geometric windows in Miami solve a problem standard window catalogs can’t: openings that are arched, angled, oversized, or shaped to suit architectural styles from Coral Gables Mediterranean to Palm Beach modern. A round porthole window overlooking Biscayne Bay, a trapezoid transom above a front door in Doral, or a full-height corner window in Kendall each requires precise fabrication and installation that off-the-shelf products simply don’t offer. Winslow Windows & Doors has designed, sourced, and installed custom and geometric windows across Miami-Dade County since 2011. Ed Winslow’s name is on the door, and on every project we take. Call (863) 862-5435 any hour, and a real person answers.
What Our Custom & Geometric Windows Service Includes
Custom Impact Windows
Miami’s building code makes impact-rated glazing the standard for most residential replacements, and custom shapes don’t get a free pass. A custom impact window carries a Miami-Dade Notice of Acceptance, meaning the frame, glass, and installation method have passed missile impact and cyclic pressure testing for hurricane zones. Winslow Windows & Doors fabricates circular, hexagonal, triangular, and other non-standard shapes with impact-rated laminated glass and reinforced aluminum or vinyl frames that meet current Florida Building Code. We handle the engineering review, the permit paperwork, and the installation, so the finished window protects your home the way code requires.
Geometric & Shaped Windows
Geometric windows are fixed, non-operable units in shapes beyond rectangles: trapezoids, parallelograms, pentagons, octagons, circles, half-circles, and quarter-circles. They bring light into gable ends, stairwell landings, and hallway transitions where a standard double-hung looks wrong. In Miami neighborhoods like Miami Shores and Palmetto Bay, geometric windows often appear in clusters that echo the home’s roofline or entry geometry. We measure each opening with digital angle finders and laser templating, then order the glass cut to match those angles within an eighth of an inch. The result is a window that fits the first time without oversized trim caulk lines or uneven reveals.
Arched & Curved Windows
Arched windows, whether full-radius half-circles or elongated eyebrow shapes, are common in Miami’s Spanish Colonial, Mediterranean, and Art Deco homes. A poorly made arch window pulls the eye immediately: the curve flattens, the frame reveals vary, or the glass distorts along the bend radius. Winslow Windows & Doors works with manufacturers who bend frame extrusions and glass to true geometric radii, not approximations. We verify the spring line, the rise, and the chord width before ordering, then set the unit with a level and plumb at every quarter point of the arch. For arched openings in historic districts like Coral Gables, we can match existing sightlines and muntin patterns so the replacement reads as original.
Oversized Openings
Oversized openings are windows that exceed standard production sizes, typically anything with a single dimension over 84 inches or a total square footage beyond manufacturer limits. Miami homes built to capture views, from Aventura high-rises to Cutler Bay waterfront properties, often pair eight-foot or ten-foot fixed picture windows with narrow sidelites. These units need heavier glass packs, sometimes tempered or laminated panes, and frames engineered for wind load and deflection limits. We calculate the structural requirement for each opening, recommend the appropriate glass thickness and frame reinforcement, and coordinate the lifting equipment and installation crew so large glass panels arrive on site safely and go in clean.

Brands We Service for Custom & Geometric Windows
Winslow Windows & Doors is an authorized installer for PGT, and we’ve built custom geometric units on PGT’s Custom Window line for homes from Hialeah to Homestead. PGT’s aluminum frames allow unusually tight radius bends for arched transoms, and we know their engineering data well enough to specify the right glass pack for a given impact zone the first time. That saves you the two-week re-quote delay homeowners often hit when a contractor misjudges frame strength on a large radius unit.
We also work extensively with CGI and ES Windows for geometric and shaped openings. CGI’s Sentinel impact line handles large-format custom shapes with strong sightlines, which matters on modern Miami homes where the frame should disappear. ES Windows, by contrast, is our go-to when the design calls for slimmer frames and larger glass, often on new construction in Coconut Grove or Key Biscayne where architects specify the brand by name. For view-focused restorations or luxury remodels, ViewLux custom finishes and hardware options give homeowners in Doral and North Miami the most control over interior aesthetics.
Whether you have a PGT, CGI, ES Windows, ViewLux, CWS, or any other make of custom or geometric window, we can measure, order, and install the correct replacement. If you’re not sure what brand is in your home now, we’ll identify the unit during the estimate and tell you exactly what you’re working with.
Signs You Need Custom & Geometric Windows Right Now
- Condensation between the panes of a shaped window. This means the insulated glass seal has failed, and the inert gas between panes is gone. In a trapezoid or radius unit, this is a custom replacement job, not a glass-swap you can buy off the shelf at a box store. Left alone, the window’s insulating value drops and the frame can begin to hold moisture, which feeds mold growth in Miami’s humidity.
- Visible frame separation at the corner joints of a geometric window. Non-square windows concentrate stress at mitered or radiused corners. If you can see a gap, or if the corner moves when you press on it, the frame’s structural bond is weakening. That’s a water intrusion point during Miami’s daily summer downpours and a failure point in a wind event.
- Daylight visible around the perimeter of an arched or circular window. The rough opening has shifted, or the original installation never matched the curve. This means the flashing and sealant are already compromised. In South Florida, where wind-driven rain comes from every direction, a perimeter gap invites water into the wall cavity within one season.
- Cracks in the glass of an oversized picture window. Oversized panes carry more thermal and wind stress than standard units. A crack that starts at the edge and creeps signals the glass was undersized for the opening or the frame is transferring pressure unevenly. On an impact-rated unit, cracked glass has already lost its hurricane performance, even if it hasn’t shattered.
- Rooms near a geometric window feel unusable during summer afternoons. Shaped and oversized windows often face south or west to capture views, but untreated heat gain can push a room ten degrees hotter than the rest of the house. We regularly replace dated curved glass in Miami Gardens and Kendall with low-E, impact-rated custom units that cut that heat transfer in half while keeping the view intact.
Our Custom & Geometric Windows Process - Step by Step
- 1
The site visit and measurement. We come to your Miami home and take every relevant dimension on the actual opening, not from the old window or the original plans. For arches and curves, we use a laser templating tool that records the precise radius and spring points. For oversized openings, we check the rough opening for square, level, and plumb before we ever order a frame. This step catches installation errors from previous work before they get repeated.
- 2
The design and engineering review. Back at our office, we match the opening to the right manufacturer and product line. This is where impact rating, frame material, glass package, and finish get locked in. We run the numbers on wind load, glass deflection, and thermal performance so the quote reflects a window that actually works in Miami’s conditions, not just one that fits the hole.
- 3
The fixed-price proposal. We hand you a written quote with a line-item breakdown for the window, the labor, the permit, and any trim or finishing work. The price on that sheet is the price we install for. No change orders down the road. You’ll also see the 36500-Day Done Right Promise in writing: if it’s not done right, we make it right.
- 4
Ordering and lead time management. Custom geometric units are made to order, and we track the production schedule with the manufacturer so you’re not left guessing. We’ll call you with updates before you have to call us. When the unit lands in our warehouse, we inspect it for frame square, glass clarity, and finish quality before it ever goes on a truck to your house.
- 5
Installation and the white-glove walkthrough. Our background-checked, uniformed technicians arrive on the scheduled day and handle the full removal and installation. For oversized panels, we bring the right lifting gear and a crew sized for the job. After the window is set, sealed, and trimmed, we walk you through the work, show you the flashing and seals, and hand you the warranty paperwork. Ed Winslow stands behind every installation personally.
How Much Does Custom & Geometric Windows Cost in Miami?
Three factors drive the cost more than any others. First, impact rating: a Miami-Dade approved laminated glass pack adds significantly to the unit cost over a standard insulated pane, but it’s code-mandated and it’s the difference between a window that protects your home and one that becomes a missile hole. Second, geometry complexity: a true radius curve costs more to fabricate than a simple trapezoid, and very small or very large radii push the price up. Third, access: a second-story arched window with poor ladder access or tight scaffolding conditions adds labor hours.
The fastest way to avoid overpaying on a custom window in Miami is to get a fixed-price quote that spells out every line item and every assumption. We provide that at the estimate, free of charge, with no trip charge inside Miami-Dade County. You’ll know what the window costs, what the labor costs, what the permit costs, and when we can start.

Frequently Asked Questions - Custom & Geometric Windows in Miami
What are custom and geometric windows?
Custom and geometric windows are non-standard window shapes or sizes made specifically for an opening in your home rather than pulled from a manufacturer’s stock catalog. They include arches, circles, ovals, trapezoids, pentagons, triangles, and oversized rectangles that exceed normal production dimensions. In Miami, these windows are frequently impact-rated and built to Miami-Dade County’s high-velocity hurricane zone requirements. Winslow Windows & Doors measures the exact opening, specifies the correct frame and glass, and manages the fabrication and installation from start to finish.
How long does custom and geometric window installation take?
Most custom and geometric window installations in Miami take one to two days on site, once the window arrives from the manufacturer. Fabrication lead time is the bigger variable: custom shaped units typically take four to ten weeks from approved order to delivery at our warehouse, depending on the brand, glass package, and whether the shape requires special tooling. We’ll give you a written schedule at the estimate so you know when to expect the work.
How much does a custom or geometric window cost in Miami?
A small fixed geometric window in Miami runs roughly $900 to $1,800 installed, while a mid-sized arched impact window falls between $1,800 and $3,500. Oversized shaped units with heavy glass can exceed $6,000 to $15,000 depending on size, impact rating, and installation access. Every window is different, which is why we provide a fixed-price written quote after measuring the actual opening. Call (863) 862-5435 to schedule a free estimate and get an exact number for your home.
Do you service PGT, CGI, and other custom window brands?
Yes. Winslow Windows & Doors is an authorized installer for PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux, and we work with custom and geometric units across every one of those lines. We have detailed knowledge of each brand’s frame engineering, glass options, and lead times, which means we can specify the right product for your opening without guesswork. If you have a different brand, we can identify it during the estimate and advise you on the best path forward.
Are you available for emergencies with broken custom windows?
We answer the phone 24 hours a day, 7 days a week, with a live person, not a voicemail tree. If a custom window breaks, whether from impact or wind-born debris, we can assess the damage over the phone and schedule a site visit to measure and board the opening if needed. Replacement fabrication still follows the lead time of the manufacturer, but we’ll make sure the opening is safe and protected immediately. Call (863) 862-5435 any hour.
What warranty comes with custom and geometric windows?
Your custom or geometric window carries the manufacturer’s warranty on the glass and frame, plus our workmanship guarantee on the installation. Our 36500-Day Done Right Promise means that if the installation isn’t done right, Winslow Windows & Doors makes it right, period. That’s a century-long standard Ed Winslow puts his name on for every job we do in Miami.
How do I prepare for a custom window installation?
Clear furniture and wall hangings at least six feet from the window on the interior, and move any plants, decor, or patio furniture away from the exterior wall. If the window is on a second floor, clear a path to the room and secure pets. Our crew lays drop cloths and protects the work area, but removing valuables and collectibles from the immediate space ensures nothing gets bumped during the removal and lifting process.
