Trusted Custom & Geometric Windows for Westchester Homeowners
Custom and geometric windows in Westchester give a home a signature look that stock rectangular units simply can’t match. Whether you’re adding an arched focal point above a front entry, creating a full wall of trapezoid glass to capture morning light, or replacing a dated half-round window that’s been leaking during hurricane season, the work requires precise measurements, engineered framing, and an installer who understands South Florida’s wind-load requirements. Winslow Windows & Doors has been doing exactly this since 2011. Ed Winslow’s name is on the door, and when you call (850) 721-1218, a live person answers, any hour, any day.
We’re the locally owned alternative to national chains that treat a geometric window as a catalog number. Around here, a custom window has to survive August humidity, afternoon thunderstorms, and the occasional named storm. So we don’t guess at load paths or hope the flashing holds. We measure, we engineer, and we install it right the first time. If it’s ever not right, our Done Right Promise means we come back and make it right. That’s a hundred years of accountability. Ed’s name is on the door, and on every job we do.
What Our Custom & Geometric Windows Service Includes
Every custom or geometric window project in Westchester starts with understanding what the opening is doing, not just what shape it is. We handle four categories of specialized work, each with its own engineering and installation requirements.
Custom Impact Windows
A custom shape doesn’t mean compromising on storm protection. We build arched, radius, trapezoid, triangle, and pentagon units with impact-rated glass that meets Miami-Dade and Florida Building Code standards. This matters in Westchester, where a shaped window on a gable end catches full wind pressure during a hurricane. We install PGT and CGI custom impact windows as authorized dealers, which means the warranty is real and we can service what we install. If you’re replacing a builder-grade shaped window with something that actually protects your home, this is the upgrade.

Geometric & Shaped Windows
Trapezoids, octagons, parallelograms, and custom angles are the defining feature of Florida contemporary homes built in the 1980s and 90s, and many of those original units are now failing. We see fogged glass, warped vinyl frames, and failed seals in Westchester homes every week. The process starts with a laser-measured template of the exact opening, then moves to factory fabrication of an insulated glass unit cut to that precise shape. Because we measure with digital equipment and order from authorized manufacturers, the new unit fits the rough opening on the first attempt, not the third.

Arched & Curved Windows
Arched and curved windows are the most demanding geometric work because the radius has to be perfect across the entire span. A half-inch error on a 6-foot arch shows up as a visible gap and creates a leak path. We template every arch with physical or digital radius measurement, then order glass and frames from manufacturers like ES Windows and ECO Window Systems that specialize in true-radius fabrication. Westchester homeowners often come to us after another contractor told them their arched window “can’t be replaced in impact glass.” Most of the time, it can. We’ve done it hundreds of times.

Oversized Openings
When a wall of glass spans 12, 16, or 20 feet, the structural load on the header and the window assembly itself changes everything. Oversized openings need reinforced framing, heavier mullions, and glass engineered to span without deflection. We handle the entire scope: structural assessment, header inspection, custom glass ordering, and installation with proper flashing details. In Westchester’s climate, the difference between a good oversized window install and a bad one shows up in the first heavy rain. We build it to shed water like the roof above it.

Brands We Service for Custom & Geometric Windows
We install and service custom geometric windows from ES Windows, a manufacturer known for narrow sightlines and true-radius capability that works beautifully on contemporary Westchester homes. Their aluminum frames hold up in coastal air, and we’ve completed enough ES Windows installations to know their radius tolerances and hardware details cold. If you already have ES Windows in place and one unit has failed, we can match the frame finish and glass package so the replacement disappears into the wall.
For impact-rated geometric work, we turn to ECO Window Systems and Mr-Glass when the job calls for specific performance tiers or budget ranges. ECO builds heavy-duty aluminum impact units that handle large trapezoid and triangle lites without excessive frame bulk. Mr-Glass gives us flexibility on custom shapes at a more moderate price point. And when a Westchester project involves a custom geometric entry door to match the glass, Therma-Tru fiberglass construction gives us the shape and the storm rating in one product. Whether you have one of these brands already or you’re starting from scratch, we can spec, order, and install it.
Signs You Need Custom & Geometric Windows Right Now
- Fog or condensation trapped between the panes. This means the insulated glass seal has failed. On a geometric or arched unit, the seal failure lets humid Florida air into the space between the glass, and it will never clear. Replacing the glass unit now is cheaper than replacing the glass plus a rotted frame later.
- Visible daylight or drafts around the frame edges. A shaped window that has shifted or settled shows gaps at the corners first, because geometric frames have more miter joints than rectangular ones. Air leaks here mean water can follow the same path during the next storm. Call before the rainy season gives you a wet floor.
- Cracked or chipped glass in any shaped unit. Impact-rated or not, a crack spreads along the stress lines of a custom shape faster than it does on a rectangle, because the glass is already under tension from the cut geometry. A small chip in a trapezoid corner becomes a full fracture with one temperature swing. Don’t wait on this one.
- Difficulty opening, closing, or locking a geometric window. Shaped windows that are operable, such as awning-style trapezoids or radius casements, depend on perfectly aligned hardware. When the frame has flexed or the hinges have worn, the sash sags and the lock no longer catches. That’s both an energy leak and a security gap.
- Staining, soft drywall, or peeling paint below the window. Water has already gotten past the flashing. By the time you see the stain inside, the rough opening may be holding moisture. We find this pattern regularly in Westchester homes where original geometric windows were flashed with builder-grade tape that gave out years ago. The fix starts with a proper removal and inspection.
Our Custom & Geometric Windows Process - Step by Step
We run custom window projects in Westchester with a process that removes guesswork and surprises. Here’s what happens from first call to final walkthrough.
- 1
Call and schedule a site visit. You reach a live person at (850) 721-1218, not a voicemail tree. We’ll set a time that works for you, and there’s no trip charge inside the home county. Ed or a background-checked, uniformed technician shows up ready to look at the actual opening, not just photos from a phone.
- 2
Measure, template, and assess the rough opening. We take laser measurements and, when the opening allows, create a physical template of the exact shape. During this step we’re also checking the header, the rough opening framing, the existing flashing, and the condition of surrounding stucco or siding. What we find here shapes the quote and prevents surprises mid-install.
- 3
Get a written, line-item estimate. You’ll receive a fixed-price written estimate that lists the window, glass package, frame finish, and installation scope. No vague “custom window, TBD” line items. If you have a competing written estimate, we’ll give you a free second opinion on it. If it’s a repair over $200, we take $40 off automatically. Seniors and veterans always receive 10% off.
- 4
We order and install. Custom units are fabricated to your exact measurements, then installed by the same crew that measured. We check the fit, set the window in the opening, flash it properly for South Florida conditions, and secure it per manufacturer and Miami-Dade requirements. We don’t sub this work out to unknown crews; it stays under our control and Ed’s accountability.
- 5
Final inspection and walkthrough. After the window is in, we water-test the flashing where practical, verify operation and lock engagement, and walk you through what we installed. If anything isn’t right, we fix it before we leave. And if something fails later, the Done Right Promise still applies. Our workmanship warranty doesn’t evaporate after the check clears.
How Much Does Custom & Geometric Windows Cost in Westchester?
Custom and geometric window pricing in Westchester varies by size, shape complexity, glass package, and whether impact rating is required. Here’s what we see on real projects in this area:
- Custom trapezoid or triangle fixed window (2-4 feet on the longest side, non-impact): $450-$950 installed
- Custom arched or half-round fixed window (3-5 feet diameter, non-impact): $700-$1,500 installed
- Impact-rated geometric fixed window (small to mid-size): $900-$2,200 installed
- Large oversized geometric opening (glass wall or stacked shapes, impact-rated): $4,000-$12,000+ installed
- Replacement insulated glass unit only for an existing shaped frame: $250-$750 per unit installed
What moves the price? The radius or angle count, the glass package (clear, low-E, tinted, impact-rated), the frame material, access conditions, and whether the rough opening needs structural repair. A second-story octagon with no interior access costs more than a ground-level trapezoid. The way to avoid overpaying is to get a written line-item quote that separates the window cost from the installation labor, and to ask whether the price locks at contract signing. Ours does. No change orders because we found “unexpected conditions” halfway through. The free estimate we give you is the price you pay unless you change the scope.

Frequently Asked Questions - Custom & Geometric Windows in Westchester
A custom or geometric & shaped window is any window shape other than a standard rectangle: arches, half-rounds, trapezoids, octagons, triangles, pentagons, parallelograms, radius corners, and oversized architectural glass. These windows are fabricated to a specific opening’s measurements rather than pulled from inventory, which is why measurement accuracy and manufacturer relationships matter so much. In Westchester, many homes built in the 1980s through 2000s feature geometric accent windows, and we replace or upgrade them regularly. Call (850) 721-1218 and we’ll walk you through what’s possible for your opening.
Custom shaped windows typically take 3 to 6 weeks from measurement to installation, depending on the manufacturer and whether impact glass is required. The fabrication time is driven by the shape complexity and the glass package, not by anything we can shortcut. We provide an honest timeline when we give you the estimate, and we give you a call when the unit ships. If you’re replacing a broken unit in an emergency, we can often install temporary weather protection while the replacement is in fabrication.
Small non-impact shaped windows start around $450 installed, while impact-rated oversized geometric openings can exceed $12,000 for large glass walls. Most mid-size custom replacements in Westchester land between $900 and $2,500 per unit when impact glass is specified. The exact price depends on the opening dimensions, glass package, frame finish, and whether structural work is needed. Call (850) 721-1218 for a free written estimate with line-item pricing, and if you have another written quote, our second-opinion review is free.
Yes. We install and service both ES Windows and ECO Window Systems custom and geometric units, along with Mr-Glass and Therma-Tru products. If you have a failed unit from one of these manufacturers, we can match the existing frame finish and glass specification so the replacement blends with the surrounding windows. We’re also authorized installers for PGT and CGI impact windows, which covers most geometric windows in Westchester homes built after 2000.
Yes. A broken or failed geometric window that’s letting in rain or creating a security risk is an emergency to us. Call (850) 721-1218 any hour, and a live person will answer, not a voicemail system. We’ll schedule a technician to assess the situation, secure the opening if needed, and order the replacement glass or window. The 10% senior and veteran discount applies to every repair, and any repair over $200 takes $40 off automatically.
Every custom and geometric window installation includes our Done Right Promise: if it’s not done right, we make it right, for as long as the workmanship holds up. Manufacturer warranties on the window itself vary by brand and product line, and we’ll give you the specific coverage in writing before you sign. We stand behind what we install because Ed’s name is on the work, and we don’t hide behind sub lists or expired LLCs. A neighbor you can call at 2 a.m., and someone will actually answer.
Clear the area inside and outside the window opening so our installers have about 6 feet of working space, and remove or cover furniture that could catch dust. We protect floors with drop cloths and clean up after the job, but clearing fragile items helps. The actual installation for a single shaped window typically takes one day from removal to final trim, assuming the rough opening is in good condition. We’ll confirm all of this before we arrive and tell you exactly what to expect.
