AfterTrusted Custom & Geometric Windows for South Miami Homeowners
Custom and geometric windows in South Miami typically cost between $1,800 and $6,500 per opening installed, depending on the shape, glass package, and framing. Most custom-shaped units take four to eight weeks from order to installation. At Winslow Windows & Doors, we’ve been designing and installing these specialty windows for South Miami homeowners since 2011, and every job carries our Done Right Promise: if it’s not done right, we make it right.
Ed Winslow’s name is on the door, and on every job we do. That means when you call (850) 930-1813 about an arched transom over your entryway or a trapezoid window catching the morning light off your living room, you’re talking to a company that answers the phone 24/7 with a live person. No call centers. No ticket numbers. Just a neighbor you can call at 2 a.m., and someone will actually answer.
This page is your complete guide to custom and geometric windows in South Miami: what they cost, how they’re installed, which brands we work with, and how to know when it’s time to replace the specialty glass in your home. If you want a price for your specific opening, skip ahead and call us. The estimate is free.
What Our Custom & Geometric Windows Service Includes
Every custom window project starts with measurements and ends with a sealed, square, code-compliant installation. Here’s what we handle under this service, broken down by the types of shaped openings South Miami homeowners ask about most.
Custom Impact Windows
Custom Impact Windows combine the same laminated-glass protection you’d find in a standard PGT or CGI hurricane window, but built to fit a non-standard opening. If your South Miami home has a round porthole window, a tall narrow sidelight, or a half-moon transom, off-the-shelf products won’t cover it. We order impact-rated glass cut to the exact dimensions and shape of your opening, so you get the same windborne-debris protection as your rectangular windows, without compromising the architectural lines of your home.
In South Miami, where wind speeds and flying debris are a genuine concern during hurricane season, skipping impact protection on a shaped window is a gamble. We’ve replaced shaped windows after storms where the glass shattered inward simply because a previous owner installed decorative, non-impact glass in a vulnerable spot. Winslow Windows & Doors is an authorized installer for CWS, ES Windows, ECO Window Systems, and Mr-Glass, all of which offer custom impact configurations for geometric shapes.
Geometric & Shaped Windows
Geometric & Shaped Windows include trapezoids, triangles, pentagons, hexagons, parallelograms, and other non-rectangular shapes. South Miami homes built in the 1960s through the 1990s often have these shapes accenting gable ends, stairwells, or vaulted ceilings. When one of these windows fails, a standard replacement won’t work. The frame and glass have to be fabricated to the exact angles of the opening, usually to within 1/16th of an inch.
We template every geometric opening ourselves. That means we don’t rely on blueprints or a contractor’s rough measurements from a decade-old renovation. One of our technicians visits your South Miami home, traces the opening, records the angles, and sends that template to the manufacturer. If the glass doesn’t match the template when it arrives, we don’t force it. We reorder. That’s how the Done Right Promise works in practice.
Arched & Curved Windows
Arched & Curved Windows come in several profiles: full radius (a perfect half-circle), quarter round, eyebrow, and gothic or cathedral arches. Curved windows can also include circles, ovals, and ellipticals. These shapes require bent framing and curved glass, and the fabrication tolerances are tighter than any rectangular window on the market. A curved window that’s off by even a few degrees will show a visible light gap or bind in the frame.
Winslow Windows & Doors has ordered and installed curved units from CWS and ES Windows for South Miami homes from Pinecrest to Coral Gables. These are not commodity products. Each one is essentially a custom furniture piece for your wall. We handle the full process: templating, ordering, coordinating with the manufacturer on radius and glass tint, and installing with the right flashing and sealants for South Miami’s humidity and rain exposure.
Oversized Openings
Oversized Openings include picture windows over 40 square feet, floor-to-ceiling gable glass, and wide horizontal bands that run ten feet or more. These openings require structural headers, heavy glass, and sometimes multiple pieces of glass joined by mullions. In South Miami’s building environment, oversized windows also need to meet Miami-Dade County’s high-velocity hurricane zone requirements if they’re impact-rated.
We’ve installed oversized impact windows in South Miami homes where the glass panels weighed over 400 pounds each. The installation is not a two-person job with a ladder. It’s a coordinated lift with suction cups, scaffolding, and careful shimming to prevent stress cracks. Ed has personally overseen oversized window installations where the only access was through a second-story balcony. That’s the level of care your job gets when the owner’s name is on the business.

Brands We Service for Custom & Geometric Windows
Winslow Windows & Doors is an authorized installer for CWS and Mr-Glass, two manufacturers that lead the industry in custom-shaped and impact-rated window fabrication. CWS is known for heavy-gauge aluminum frames and wide-span capability, which makes them a go-to for oversized openings and modern architectural styles with narrow sightlines. We’ve templated and installed CWS custom units in South Miami homes where the architect specified slim profiles but demanded Miami-Dade impact compliance. CWS delivers on both.
Mr-Glass has a strong lineup for vinyl custom windows, including arched and shaped units that fit mid-century and Mediterranean-style South Miami homes without the cost of full aluminum fabrication. ECO Window Systems and ES Windows round out our custom capabilities, particularly for homeowners who want European-style tilt-and-turn hardware or thermally broken frames in a non-standard shape. If you already have a PGT or CGI shaped window from a previous install and it’s failed, we can service or replace it as well. Whether your home has any of these brands or something else entirely, we can help.
Signs You Need Custom & Geometric Windows Right Now
Shaped windows fail in the same ways rectangular windows do, but the consequences can be harder to spot. Here are the five warning signs we see most often in South Miami homes.
- Condensation between the panes of a shaped window. When the seal on a double-pane geometric window fails, moisture gets trapped between the glass layers. You can’t wipe it off. It means the insulating gas has escaped and the window’s energy performance is gone. In South Miami’s humidity, the condensation can also grow mold inside the glass assembly. Replacement is the only permanent fix.
- Visible cracks running from corner to corner. Shaped windows carry structural stress at their corners: a triangle window concentrates load at each vertex, and an arch redirects it along the curve. Once a crack appears, it spreads. In an impact-rated window, a crack compromises the laminate’s ability to hold the glass together during a storm. Don’t wait on this one.
- Difficulty opening or closing a shaped operable window. Some geometric windows, particularly awning-style trapezoids and hopper shapes, are operable. If the sash binds, the hinges creak, or the window won’t seal tight, the frame may have racked out of square due to settling or thermal expansion. Forcing it will only make the problem worse.
- Water staining on the drywall or trim beneath an arched or curved window. Curved and arched windows depend on perfectly fitted flashing to shed water. When the flashing fails, water runs down the interior wall and shows up as discoloration, bubbling paint, or soft drywall. By the time you see the stain, the leak has been active for a while. A properly templated and flashed replacement stops the cycle.
- Drafts or temperature swings near a shaped window in a main living area. A geometric window over a stairwell or foyer can leak air around the frame, even if the glass is intact. South Miami’s afternoon heat makes a leaky window an expensive air-conditioning problem. If your AC runs longer on one side of the house, check the shaped windows.
If any of these apply to a window in your South Miami home, call (850) 930-1813. We’ll give you an honest read on whether it’s a repair or a replacement, and estimates are always free.
Our Custom & Geometric Windows Process - Step by Step
Here’s how a custom or geometric window project works with Winslow Windows & Doors, from first call to final walkthrough. No steps skipped. No “we’ll figure it out on site.”
- 1
Phone consultation and site visit. You call (850) 930-1813. A live person answers, day or night. We ask about the window: its shape, approximate size, what’s wrong with it, and where it’s located in the home. Then we schedule a visit. If you’re in South Miami, there’s no trip charge inside our home county, and we arrive on time with a background-checked, uniformed technician.
- 2
Measurement and templating. The technician measures the opening with precision instruments and creates a physical template of the exact shape. For complex curves, we use a digitizing template that records the radius and arc to the millimeter. This step is what separates a window that drops in cleanly from one that gets caulked and shimmed into submission. We also inspect the surrounding framing for rot, termite damage, or structural issues that would affect the installation.
- 3
Upfront quote with no surprises. Within a few days, you get a written, line-item estimate. It shows the cost of the window, the frame material, the glass package, the installation labor, and any structural work required. Our pricing is fixed once we sign. No change orders down the line, no “unforeseen conditions” add-ons. If you already have an estimate from another company, we’ll give you a free second opinion on it. And if it’s a repair over $200, you get $40 off automatically.
- 4
Order and fabrication. Once you approve the quote, we order the window from the manufacturer with the exact template dimensions and specifications. This is the part that takes time. Most custom windows arrive in four to eight weeks, depending on the manufacturer’s production queue and the complexity of the shape. We track the order and keep you updated. We don’t disappear for two months.
- 5
Installation and cleanup. The day of installation, we remove the old window, inspect the rough opening, correct any issues, and set the new window. Custom-shaped units get extra attention on shimming, squaring, and flashing. We use sealants rated for South Miami’s UV exposure and rainfall. At the end of the day, we haul away the old window and all debris. Then we walk the job with you and make sure you’re satisfied before we leave.
Every step of that process is backed by a promise that’s hard to match: if it’s not done right, we make it right. The Done Right Promise isn’t a warranty buried in fine print. It’s Ed Winslow’s word, and Ed’s name is on the door.
How Much Does Custom & Geometric Windows Cost in South Miami?
A typical custom geometric window in South Miami runs between $1,800 and $6,500 installed. A small, fixed, non-impact triangle vent over a bathroom runs at the lower end. A large impact-rated arched window over a front entryway runs at the higher end. Oversized openings that require structural headers and impact glazing can exceed $8,000, and we’ve quoted and installed projects in the $12,000 to $20,000 range for full gable-end glass walls. Every opening is different. That’s why the free estimate matters.
What drives the cost? The shape is the biggest factor. A trapezoid requires more engineering and waste in fabrication than a square. Curved glass costs more than flat glass. Impact-rated laminated glass costs more than standard tempered glass. Frame material matters too: aluminum is more expensive than vinyl but handles larger spans and carries the Miami-Dade impact approvals some homeowners need. Installation complexity adds labor: a second-story arched window over a hard-to-reach roofline costs more to install than a first-floor geometric window with ladder access.
To avoid overpaying, get a written line-item estimate and compare it against a second opinion from us, free of charge. Watch for vague quotes that lump materials and labor together without showing the breakdown. And don’t accept a bid that doesn’t include the flashing, sealants, and disposal. Those details matter in South Miami’s climate. Our free estimate includes everything: the window, the install, the flashing, the cleanup, and a written price that won’t change once you sign.

Frequently Asked Questions - Custom & Geometric Windows in South Miami
Custom and geometric windows are any windows that don’t come in a standard rectangular size from a manufacturer’s catalog. They include triangles, trapezoids, pentagons, hexagons, circles, ovals, half-moons, eyebrows, and arches. South Miami homes use these shapes for architectural character, especially above entryways, in gable ends, and along stairwells. Because they’re non-standard, each one is fabricated to order using a template of the exact opening.
Most custom-shaped windows take four to eight weeks from order to installation, depending on the manufacturer and the complexity of the shape. The templating and ordering process takes the first week, fabrication takes three to six weeks, and installation takes one day for a single opening. Larger multi-window projects add installation days. We’ll give you a realistic timeline when we quote the job, and we’ll call you with updates while the window is in production. Call (850) 930-1813 to get started.
Custom geometric windows in South Miami typically cost $1,800 to $6,500 per opening installed. Small fixed triangles and non-impact shapes run at the low end, while large impact-rated arched or curved windows run higher. Oversized openings with structural work can exceed $8,000. The exact price depends on the shape, glass type, frame material, and installation access. We provide a free written estimate with a fixed price, so you know the number before you commit.

Yes. If a geometric or custom window in your South Miami home is broken, call (850) 930-1813 any time, day or night. A live person will answer, not a voicemail system. We’ll assess the situation over the phone, prioritize your call if it’s a security or water-entry risk, and get a technician out as soon as possible.

Every custom and geometric window installation by Winslow Windows & Doors is covered by our Done Right Promise: if it’s not done right, we make it right. Manufacturer warranties on the glass and frame apply separately and vary by brand. What makes us different is that Ed Winslow personally stands behind the installation. You’re not chasing a national chain’s claims department. You’re calling the owner’s phone. That’s the warranty that matters.
Clear the area around the window inside and out: move furniture, remove wall hangings near the opening, and trim back any landscaping that blocks exterior access. If the window is on a second story, make sure the hallway or room leading to it is clear for our team and equipment. We handle the rest, including floor protection, dust control, and haul-away. Preparation takes about fifteen minutes of your time and makes the install day run much smoother.
