Trusted Custom & Geometric Windows for Miami Beach Homeowners
Custom and geometric windows in Miami Beach typically run $1,400 to $5,800 per opening depending on shape, size, impact rating, and frame material. Most specialty window projects take four to eight weeks from template to installation. That’s the straight answer upfront, because the last thing a Miami Beach homeowner needs is another vague estimate that doubles once the job starts.
Winslow Windows & Doors has been fabricating and installing shaped windows across Miami Beach since 2011. Ed Winslow’s name is on the door – and on every job we do. We’ve built circular picture windows for Mid-Beach condos, eyebrow arched openings for North Beach villas, and trapezoid transoms for South of Fifth penthouses. Each one came with a real line-item quote, a real timeline, and the 36500-Day Done Right Promise backing every cut, every seal, and every bead of caulk. When you’re ready to talk specifics, call (863) 656-0462 and a live person picks up. Not a call center. Not a voicemail tree.
What Our Custom & Geometric Windows Service Includes
Every custom window in Miami Beach starts with a site measurement, not a catalog guess. We template the opening digitally, match the radius of your arch, record the exact angle of your corner window, and verify rough openings before anything gets ordered. Then we build to fit your opening – not the other way around. Here’s what this covers, piece by piece.
Custom Impact Windows
Miami-Dade County’s building code is the strictest in Florida, and for good reason. A custom impact window must hold its shape and glass under wind loads that would turn a standard window into confetti. We design and install custom impact windows that meet Miami-Dade HVHZ standards, using laminated glass and reinforced frames from CWS and ES Windows. If you have an unusual opening – a hexagonal accent window, a floor-to-ceiling fixed pane beside a pivot door, a slim vertical sidelight – we can make it impact-rated without making it ugly. The frame profile stays clean, the sightlines stay slim, and the glass survives what the Atlantic throws at it.

Geometric & Shaped Windows
Geometric & shaped windows – triangles, trapezoids, pentagons, parallelograms, octagons – if your architect drew it, we’ve probably built one. These windows usually show up above doors, in stairwells, or as the centerpiece of a modern facade. The challenge isn’t just cutting the glass; it’s engineering the frame so the window drains properly and doesn’t rack over time. We order from manufacturers that specialize in non-rectangular glazing, then verify every diagonal before the unit leaves the shop. The result is a window that fits square instruments dead-on, even when visually nothing about it is square.

Arched & Curved Windows
Arched & curved windows are the signature of Miami Beach’s Mediterranean revival homes from the 1920s and the contemporary townhomes modeled after them. A true radius window is templated to match the curve exactly – half an inch off and the whole facade looks wrong. We’ve matched existing arches down to the radius point, including the brick-ledge arches common in Flamingo Park and the tall Spanish arches in La Gorce. Curved glass is available for select custom projects, but we’ll walk you through the cost difference honestly before you commit.

Oversized Openings
Oversized openings like floor-to-ceiling glass, panoramic corner windows, and sliding glass walls that span twenty feet or more fall into this category. The permitting process changes, the structural load calculations matter, and the glass gets much heavier. We pull the permits, we work with your structural engineer, and we coordinate crane delivery when the opening demands it. Oversized custom projects on Miami Beach’s waterfront require extra attention to corrosion resistance too – salt air eats standard hardware. Our oversized installs use stainless and marine-grade components so the window operates smoothly year after year.

Brands We Service for Custom & Geometric Windows
We’re an authorized dealer and installer for CWS and ES Windows, two Florida-based manufacturers that build some of the most respected custom and impact-rated window lines in the industry. On CWS units we’ve handled everything from standard impact sliders to custom-radius fixed windows with laminated glass. We know their frame depths, their hardware options, and their lead times. If you have a CWS window that’s fogging, leaking, or missing hardware, we can source what it needs without guesswork.
ES Windows is another brand we install regularly. Their thermally broken aluminum frames are a strong choice for mid-century modern homes in Normandy Isles and Biscayne Point, where clean lines and big glass matter. We’ve also installed ECO Window Systems and Mr-Glass when a project calls for a particular frame style or budget point. Whether you already have one of these brands in your home or you’re shopping from scratch, Ed can walk you through what each line does well – and what it doesn’t – before you spend a dollar.
Signs You Need Custom & Geometric Windows Right Now
- Visible cracking or stress fractures around the corners of a shaped window. Non-rectangular windows concentrate stress at the corners. A crack that starts there is spreading, and in a Miami Beach storm season, that’s the window that fails first. We’ll assess whether it’s repairable or needs full replacement before you lose a pane.
- Water staining on drywall beneath an arched or curved window. Arched windows tend to leak at the apex if the flashing wasn’t laid correctly at install. The stain you see now is the leak that’s been happening for months. We find the entry point, repair the surrounding framing if needed, and reseal the window so it drains properly.
- Fogging or condensation between glass layers in a custom impact unit. Once the argon or krypton gas escapes, the window’s insulation value is gone. On impact windows this also means the laminate seal is compromised. Replacement is the right call, and we’ll match the new unit to your existing frame’s exact size and tint.
- Stiff operation or warped frames on oversized openings. A twenty-foot sliding glass wall that drags or sticks is telling you the frame is racking. That’s a structural issue, not a WD-40 issue. We inspect the track, the rollers, and the header to determine if the frame is settling or the hardware has failed.
- You’re renovating and the old standard-size windows no longer fit the design. This is a planning problem, not an emergency, but it becomes one fast if you order windows late. Custom geometric windows have 6-10 week lead times. Pull us in during the framing phase so your openings get templated before drywall goes up.
Our Custom & Geometric Windows Process - Step by Step
- 1
Call and talk to a human. You call (863) 656-0462. Someone answers – 24 hours a day, 7 days a week. You describe the window, the opening, the problem, or the plan. We ask the right questions: Is it impact-rated? What year was the home built? What direction does the wall face? You’ll know quickly if this is a project we should take on.
- 2
Free on-site measurement and consultation. We come to your Miami Beach property, take digital measurements, photograph the opening, and check the surrounding structure. No trip charge if you’re in our home county. You’ll get our honest read: repair versus replace, what’s realistic for the budget, and what the building department will require.
- 3
Written line-item estimate, not a ballpark. Every estimate includes material cost, fabrication lead time, installation labor, permits, and disposal. If another company gave you a written bid, bring it – our free second opinion means we’ll review it and tell you if you’re being overcharged. Permanently. Not a seasonal promo.
- 4
Fabrication and preparation. We order the window from the manufacturer that best fits the project, then verify the order spec line by line. When the unit arrives, we inspect it for damage, confirm dimensions, and check the glass rating. Then we schedule install around your timeline and the weather window.
- 5
Installation and the Done Right walkthrough. Our background-checked, uniformed technicians remove the old unit, prep the opening, flash and seal the new window, and clean the site. Ed reviews the final work with you and walks you through what was installed. If anything isn’t right, it gets fixed. That’s the 36500-Day Done Right Promise – a century of accountability, not a five-year fine-print warranty.
How Much Does Custom & Geometric Windows Cost in Miami Beach?
A fixed custom geometric window (triangle, trapezoid, or pentagon) in Miami Beach generally runs $1,400 to $4,200 installed, depending on glass package and size. A custom arched window falls between $1,800 and $5,800, with the higher end reflecting true radius frames and impact-rated laminated glass. Oversized openings with floor-to-ceiling custom glass can push past $10,000 when structural reinforcement, crane delivery, and Miami-Dade permitting enter the picture. These are real numbers from real Miami Beach projects – not website-generated ranges designed to get a call.
What swings the price: glass type (standard insulated versus impact-rated laminated), frame material (aluminum versus thermally broken aluminum), radius complexity, and access difficulty. A third-floor penthouse window on Collins Avenue costs more to install than a ground-level bungalow window on Michigan Avenue. What doesn’t change the price: our markup after the fact. Fixed pricing means the number on the estimate is the number on the invoice. No change orders because we underbid to win. No surprises on the invoice. Estimates are always free, and seniors and veterans take 10% off permanently. Call (863) 656-0462 for a real number on your window.

Frequently Asked Questions - Custom & Geometric Windows in Miami Beach
Custom and geometric windows are any windows that aren’t standard rectangular shapes – triangles, trapezoids, hexagons, arches, circles, and oversized glass walls. They’re typically ordered to fit a specific architectural opening rather than purchased off a shelf. In Miami Beach, these windows often appear in Mediterranean revival homes, contemporary beachfront designs, and mid-century modern builds. We design, source, permit, and install these windows to Miami-Dade building code.
Most custom geometric window projects take four to eight weeks from the day we template the opening to the day installation is complete. Fabrication lead time accounts for most of that window; the installation itself is usually completed in one to three days depending on how many openings are involved. We give you a written timeline with the estimate so you know exactly what to expect. Call (863) 656-0462 and we’ll tell you current lead times for your specific window type.
A single custom geometric window replacement in Miami Beach typically costs between $1,400 and $5,800, with impact-rated units and true radius shapes at the higher end of the range. The exact price depends on the glass, the frame material, the size, and whether structural work is needed. We provide a free in-home estimate with line-item pricing so you can see exactly where every dollar goes. There’s no charge for the estimate itself.
Yes, we’re an authorized dealer and installer for both CWS and ES Windows. We’ve installed and serviced hundreds of units from these Florida manufacturers across Miami Beach and the surrounding barrier islands. Whether you need a new custom CWS impact window or hardware for an existing ES Windows unit, we know these brands inside and out. Give us a call at (863) 656-0462 and tell us what you’re working with.
We answer the phone 24 hours a day, 7 days a week, and we’ll dispatch a technician to assess urgent window failures. If a geometric window has cracked and left your home exposed, we can board it temporarily, then order the replacement unit on a rush. Miami Beach’s storm season makes broken custom windows a real safety issue, and we treat it as one. Call us any hour – a real person picks up.
Every custom window we install carries the manufacturer’s warranty on the glass and frame, plus our 36500-Day Done Right Promise on the installation workmanship. That promise means if our work isn’t done right, we come back and make it right – period. Ed Winslow’s name is on every job, and a hundred-year standard of accountability is the one we set for ourselves. You’ll get all warranty terms in writing before the job starts.
Clear a wide path to the window opening – furniture, art, and window treatments should be moved back at least six feet. Our crew handles floor protection and dust control, but fragile items near the work area should be relocated for their safety. For oversized opening installations, we’ll coordinate with your building or HOA ahead of time. You’ll get a pre-install checklist when we confirm the date so there are no surprises the morning we arrive.
