Trusted Custom & Geometric Windows for Miami Shores Homeowners
Custom and geometric windows in Miami Shores generally run anywhere from $900 to over $6,000 per window, depending on the shape, glass package, and whether impact rating is required, and most projects take two to six weeks from measurement to installation. Winslow Windows & Doors has been handling these precise, form-and-function window projects since 2011, and we’re the local crew Miami Shores homeowners call when a standard rectangle simply won’t do. Ed Winslow’s name is on the door, and on every job we do. If you’re looking at an arched transom, a trapezoid over a staircase, or a full wall of glass that needs to meet Miami-Dade impact code, call (727) 483-7883 and a real person will answer, day or night.
Living in Miami Shores means working with houses that have real architectural character: mid-century ranches, Mediterranean revival, Key West style bungalows, and the occasional modern build with dramatic sightlines. A big-box store will sell you stock rectangles and tell you to reframe the opening. We don’t. We build and install windows that match what the architect drew in 1952 or what your designer sketched last month. As an authorized installer for ES Windows, ECO Window Systems, Mr-Glass, and Therma-Tru, we have the manufacturing partners to make nearly any shape a reality, with impact glass that passes Miami-Dade County’s strictest requirements.
We’ve also been around long enough to have replaced plenty of custom windows that other installers got wrong: the arch that leaked at the spring line, the triangle that never seated square, the eyebrow window that fogged within a year. A misshapen window isn’t just an eyesore. It’s a structural weakness and a moisture path into your walls. The Done Right Promise means we stand behind every custom window we install for as long as you own the home. If it’s not done right, we make it right. Period.
What Our Custom & Geometric Windows Service Includes
Custom Impact Windows
Custom impact windows combine a non-standard shape with laminated, impact-rated glass and heavy-duty frames that meet Miami-Dade and Florida Building Code requirements for wind-borne debris protection. You need this when your home is in a wind-borne debris region, which includes all of Miami Shores, and you want a uniquely shaped window without adding shutters or plywood. Winslow Windows & Doors works directly with authorized manufacturing partners to fabricate shaped impact windows that carry the proper product approvals, and our crew handles the structural anchoring, permitting, and inspection process from start to finish.

Geometric & Shaped Windows
Geometric windows include any non-rectangular shape: trapezoids, triangles, pentagons, hexagons, circles, half-rounds, and quarter-rounds. These windows often appear as accent pieces above doors, in stairwells, in gable ends, or as clustered feature windows that create a focal point in a living room. We measure every angle precisely, often using digital templating to capture the exact opening, then build a frame and sash that fits within a sixteenth of an inch. Our team has installed geometric windows in Miami Shores homes ranging from 1930s Spanish revivals to brand new waterfront builds where the architect wanted a staircase wrapped in angled glass.

Arched & Curved Windows
Arched and curved windows include true radius arches, ellipse tops, eyebrow windows, and segmental arches. These are the shapes that give a home its proportion and curb appeal, and they’re also the shapes most likely to fail if fabricated or installed poorly, since curves put different stress on frames and glazing than straight runs do. We order every curved window with the glass cut to the exact radius of the opening, using full-scale templates rather than relying on field measurements alone. Winslow Windows & Doors has replaced enough leaking arches in Miami Shores to know that the difference between a 20-year window and a 5-year window is a couple of millimeters at the spring line, and we build to the number, not to the hope.

Oversized Openings
Oversized custom windows are large-format or multi-panel configurations that exceed standard stock sizes, often spanning eight, ten, or more feet across a living room or great-room wall. These openings require engineered headers, glass that’s thick enough to resist flex and wind load, and frames that can carry hundreds of pounds without sagging over decades. We work with ECO Window Systems and ES Windows to specify oversized impact-rated units that maintain clean sightlines while meeting structural requirements. Our installation crew has the equipment to set 400-pound glass panels safely, and we never shortcut the structural engineering review on a large opening in Miami Shores, because a sagging header doesn’t announce itself until the drywall starts cracking.

Brands We Service for Custom & Geometric Windows
Winslow Windows & Doors is an authorized installer for some of the most respected custom window manufacturers in the impact and architectural glass industry. ES Windows is one of our go-to partners for oversized and shaped impact windows, and we’ve specified their products on high-end Miami Shores homes where the owner wanted European engineering with Miami-Dade product approval. We know their catalog, their hardware options, and their lead times, so when you call, we can speak to what’s actually buildable rather than reading from a brochure.
ECO Window Systems is another partner we lean on heavily for geometric and shaped windows, particularly for homeowners who want energy-efficient glazing with a modern aesthetic. Mr-Glass has been our source for specialty curved glass and arch fabrication when the radius is outside what stock units can deliver. And Therma-Tru, while better known for doors, supplies entry systems that often integrate transoms and sidelites that complement custom window work. Whether you have one of these brands already in your home, or you’re starting fresh, we can spec, order, and install it. If you have another manufacturer’s window in a shape that needs service, we can help with that too.
Signs You Need Custom & Geometric Windows Right Now
- Condensation between the panes of an arched or shaped window. That fog means the seal has failed and the insulating gas has escaped. On a rectangular window, that’s a service call. On a curved or geometric window, it’s a fabrication job, because the glass unit has to be cut exactly to the radius and rebuilt with the correct spacer. If left alone, the window loses its energy efficiency and can develop staining inside the glass that won’t come clean.
- Water staining on the drywall or window sill below a curved or angled window. Leaks at the top of an arch, or along the sloped leg of a trapezoid, are usually a flashing or installation problem that was baked in on day one. In Miami Shores, our afternoon downpours will find any gap in the weatherproofing. We trace the water entry point, remove the window, correct the rough opening, and reinstall with layered flashing that sheds water the way the curve was designed to.
- A visible gap or separation where the window frame meets the stucco or wood trim. That gap is a sign of house settling or poor original installation, and it’s also an entry point for insects, humidity, and wind-driven rain. On a shaped window, a small gap can grow quickly because any racking in the frame gets concentrated at the corners. We inspect the full perimeter, and often the fix is a proper reset rather than a bead of caulk.
- You can hear traffic, wind, or neighbors through a closed window. A custom window that’s performing well should seal tightly against sound and air. If you’re hearing outside noise through the glazing, the gaskets may be compressed, the sash may not be seating fully, or the glass unit is thinner than the opening demands. In Miami Shores, where we live close to NE 2nd Avenue and the commuting corridors, a quiet house is a quality-of-life issue, not a luxury.
- You’re planning a renovation or addition and the existing windows don’t match the new design. This is the good version of needing custom windows. If you’re extending your living room, adding a second story, or rebuilding after storm damage, you have one chance to get the fenestration right. We’ll come out with the plans, check the rough openings against the architect’s elevations, and order windows that arrive the right shape, the right size, and the right impact rating the first time.
Our Custom & Geometric Windows Process - Step by Step
- 1
Measure and template. We start with a site visit to measure every opening, not just once but in multiple directions to account for out-of-square conditions. For arched and curved windows, we cut a physical or digital template that captures the exact radius, because even a quarter-inch deviation on an arch is visible to anyone standing in the room. We also confirm the structural framing and check for any rot, termite damage, or water intrusion that would need repair before a new window goes in.
- 2
Specification and quote. Once we have the measurements, we put together a written, line-item quote that shows the window unit cost, glass package, frame finish, hardware, and installation labor as separate lines. No allowances, no vague “miscellaneous” line items, no change orders hiding in the paperwork. The price we quote is the price you pay, and it includes permits where the municipality requires them.
- 3
Ordering and fabrication. We place the order with the manufacturer and track it through production. Custom geometric windows typically take three to six weeks to fabricate, depending on impact rating and the complexity of the shapes. During this phase we’ll keep you updated on the production timeline, and we’ll coordinate the permit application and inspection schedule so there’s no gap between the windows arriving and the install crew getting to work.
- 4
Removal and installation. Our crew arrives in uniform, background-checked, and with a trailer set up for glass handling. We remove the existing window carefully to avoid damaging the surrounding stucco or trim, then set the new window in the opening with shims placed to support the weight where the manufacturer specifies. For oversized and impact units, we use leveling crews and suction rigs to set the glass without strain. Every window is flashed, sealed, and anchored to the manufacturer’s installation instructions and Miami-Dade code requirements.
- 5
Inspection and clean-up. After installation, we walk the job with you, show you how each window operates, and confirm the seals are seated and the glass is clean. We handle the municipal inspection if one is required, and we don’t consider the job done until you’ve signed off. Our Done Right Promise is the standing warranty on top of the manufacturer’s coverage. If something’s not right, we come back and make it right. End of story.
How Much Does Custom & Geometric Windows Cost in Miami Shores?
A typical custom impact window in Miami Shores runs between $1,800 and $4,500 per unit for most geometric shapes, while a large arched or oversized unit can reach $6,000 to $12,000 depending on the glass package and frame material. Smaller accent shapes like a fixed triangle or quarter-round usually fall in the $900 to $1,600 range when built with standard insulated glass, and expect to add 20 to 35 percent for impact-rated laminated glass. These numbers are installed prices that include anchoring, flashing, exterior trim, and debris haul-away.
What drives the price: the number of straight cuts and the tightness of the radius, the glass type (laminated impact is pricier than annealed or tempered), the frame material (aluminum, vinyl, or wood-clad), and whether the window is fixed or operable. Casement and awning hardware on a shaped window adds cost because the hardware has to be engineered to operate on a curved or angled sash. The best way to avoid overpaying is to compare apples to apples: make sure every quote lists the same glass package, the same frame, and the same installation scope. Our estimates are free, written, and line-itemed, and we’ll walk through the numbers with you so you understand exactly what you’re paying for. If you already have a quote from another installer, bring it in and we’ll give you a free second opinion.

Frequently Asked Questions - Custom & Geometric Windows in Miami Shores
A custom window is any window that isn’t a standard rectangular size or shape, including arches, circles, triangles, trapezoids, and angled accent windows. In Miami Shores, many homes built in the 1920s through 1950s feature these shapes as architectural signatures, and replacing them means fabricating a unit to match the existing opening exactly rather than forcing a stock window in. Winslow Windows & Doors measures, templates, and orders shaped windows built for your specific openings.
Most custom geometric window projects take two to six weeks from initial measurement to completed installation. Measurement to quote is typically a few days, permitting adds one to two weeks depending on the municipality, and manufacturing takes three to six weeks for shaped or impact-rated glass. We keep you updated at each stage, and we schedule your installation slot before the windows ship so there’s no delay between delivery and install. Call (727) 483-7883 to get a timeline for your specific shapes.
Custom geometric windows in Miami Shores typically run $900 to over $6,000 per unit, with impact-rated curved or oversized windows at the high end. A small fixed geometric accent with standard glass starts around $900 to $1,600, while a large arched impact window in a living room can run $6,000 to $12,000. The exact number depends on the shape, glass package, frame, and whether the window operates or is fixed. We’ll give you a free written estimate with every dollar broken out before you commit.
Yes, Winslow Windows & Doors is an authorized installer for ES Windows and ECO Window Systems, and we service existing installations from both manufacturers. We also work with Mr-Glass for specialty curved units and Therma-Tru for entry systems that incorporate transom and sidelite glass. If your home has a custom window from a brand we don’t carry, we can still evaluate and often service it, since our team handles fabrication geometry independent of brand.
Yes, and when you call (727) 483-7883, a live person answers, 24 hours a day, 7 days a week. A broken custom window in Miami Shores is a security and weather-exposure problem, so we treat it as a priority. We can tarp, board, and secure an opening in most cases, then move into measuring and ordering the replacement. You won’t get a voicemail tree or a call center; you’ll get a person who can get a crew moving.
Every custom window we install is covered by the manufacturer’s product warranty plus our Done Right Promise, our standing commitment to make the job right if it’s not done correctly. That means if an installation issue shows up five, ten, or twenty years down the road, we come back and fix it. On top of that, we’re licensed and insured with a published address, so the business you’re hiring is one you can find and hold accountable in Miami Shores.
The preparation is simple: clear a path from the entry to the window, move furniture and wall hangings near the opening at least six feet back, and remove any window treatments. If the crew needs to work outside, we’ll need access to the exterior wall and a place to set up the glass-handling equipment. We protect floors with drop cloths and run a dust barrier when the removal generates debris, and we clean the site before we leave. A little prep on your end keeps the job moving fast, and we’ll walk you through everything on the phone before the install day.
