Fast, Reliable Custom & Geometric Windows Across Westchester
Custom and geometric windows in Westchester typically run $2,500 to $5,000 per custom opening installed, with standard impact windows running $800 to $1,500 per unit. Most jobs in Westchester take four to six weeks from order to install because every custom shape is fabricated to the exact opening, and structural window work here almost always requires a Miami-Dade permit. If you’re weighing a jalousie-to-impact conversion or an oversized arched window on a CBS ranch, call Winslow Windows & Doors at (863) 862-5435 for a free in-home measure and a written quote before you commit to a design.
Westchester’s homes are mostly single-story CBS ranch houses from the 1950s through the 1970s. The solid block walls change everything about how a custom window gets specified, anchored, and permitted. Ed Winslow has built this company since 2011 around exactly that reality: the 36500-Day Done Right Promise means if a window is not done right, we come back and make it right. A century-long standard of accountability, from a company with a published address and license number, not a ticket number.
Why Winslow Windows & Doors Is Westchester’s Preferred Custom & Geometric Windows Company
Westchester customers call us because we answer the phone. Not a call center. A live person, 24 hours a day, reads the local permit code and asks the right questions before we ever schedule the measure. That matters when you have an original 1960s jalousie window on a Florida room and you need to know whether the county will flag it on a wind mitigation report. We know the answer, because we’ve pulled permits on SW 16th Street, worked on homes off Coral Way, and measured openings near Tropical Park and Bird Road. Westchester is not a generic Miami suburb to us. It’s where our crews anchor impact frames into hollow block every week.
Every technician who arrives at your door is background-checked and in uniform, so you know who you’re letting in before the truck parks. We’re an authorized installer for PGT, CGI, and ES Windows, and we match the exact Miami-Dade Notice of Acceptance (NOA) to the opening, not the other way around. Westchester homeowners have dealt with too many vague estimates and no-show crews. Our pricing is upfront and line-itemed, and we offer a free second opinion on any written estimate you already have. No trip charge inside the home county, ever.
Our Custom & Geometric Windows Services in Westchester
Our Custom & Geometric Windows team handles everything from a single radius sash to a full wall of shaped openings on a Westchester remodel. Here’s what we most often do in this neighborhood:
Custom Impact Windows
In Westchester, custom impact windows are not a style choice. They’re the law. Nearly every replacement must carry a Miami-Dade NOA for the exact configuration, and on CBS block homes that means anchoring through a direct-mount masonry system rated for the opening’s design pressure. We spec laminated glass interlayers, corrosion-resistant frames, and NOA numbers that match the shape of the window, not just the square footage. That’s the difference between passing a county inspection and storing a custom unit in a warehouse because the Florida Product Approval did not cover the arch.

Geometric & Shaped Windows
Westchester’s 1950s and 1960s ranch homes still carry original trapezoid, circle-top, and angle-cut windows that most installers will not touch. We will. Triangles, pentagons, half-rounds, and custom rake windows all get the same treatment: field measure, digital template, shop drawing, then NOA verification before fabrication. The mistake we see most often from competing quotes is a salesperson promising a shape without checking whether the county’s product approval actually covers it. We check first.

Arched & Curved Windows
An arched window on a Westchester CBS block wall is a structural project, not a swap. The arch carries the same wind load as the flat openings next to it, which means the header, anchor spacing, and glass interlayer all have to meet the same design pressure. We recently converted a 1962 CBS ranch on SW 16th Street from a wall of rusted jalousie panels to a single oversized arched PGT impact window with a laminated interlayer. That job required cutting a new opening in block, engineering the arch, and pulling a county permit before the insulated glass unit could even be ordered. The homeowner’s wind mitigation report now credits every opening in the house.

Oversized Openings
Oversized custom openings in Westchester often mean removing a wall of jalousies on a Florida room or carport and replacing it with a single fixed picture window plus operable impact sliders on the sides. The glass gets heavy, the anchors go deep into block, and the crane or lift access on a tight 7,500-square-foot lot can change the install plan. We scope that before quoting, not after you’ve signed.

Trusted Brands We Service in Westchester
We install and service PGT, CGI, and ES Windows for Westchester homeowners, and we’re authorized across the full lineup rather than carrying a single brand and forcing it into every opening. PGT’s WinGuard and CGI’s Sentinel lines both offer Miami-Dade NOA-rated geometric and arched configurations, which is the real question in this area: does the brand’s product approval cover your exact shape? We stock common replacement parts and glazing for these lines locally, so service work in Westchester turns around faster than a special order from the factory when we can avoid it.
Common Custom & Geometric Windows Problems We See in Westchester Homes
- Jalousie windows flagged on wind mitigation reports. Miami-Dade inspectors have seen every version of the original louvered jalousie on Westchester carports, Florida rooms, and baths. Insurers increasingly refuse to credit or renew policies with jalousies present, which makes a jalousie-to-impact conversion one of the most common urgent calls we get in this ZIP.
- Frames pulling loose from hollow CBS block. A custom impact window anchored into block without a masonry anchor spec matched to the NOA will fail the county’s hurricane inspection. The windows can be beautiful and still not be code-compliant.
- Salt-laden humidity corroding untreated aluminum frames. Westchester sits roughly 7 to 10 miles inland from Biscayne Bay, far enough to feel the full Atlantic wind load, close enough that untreated aluminum frames break down within a few years. Original single-pane aluminum sliders throughout the neighborhood are at or past the end of their service life.
- Custom radius sashes ordered before the Florida Product Approval was verified. This is a warehouse full of glass waiting for a permit that will not come. The county rejects the application, the homeowner pays storage, and the original window stays in the wall. We verify before fabrication starts, every time.
Pricing for Custom & Geometric Windows in Westchester, FL
In Westchester, a standard impact window runs $800 to $1,500 per window installed, and a single-hung impact unit runs $900 to $1,800. Custom geometric, arched, or oversized openings sit in the $2,500 to $5,000 range per opening because the glass is cut to template, the NOA match is exact, and anchoring into block costs more than anchoring into wood framing. Whole-home packages on a three-bedroom CBS ranch typically land between $8,000 and $25,000 or more, depending on opening count, wind zone, floor height, and frame material.
The honest answer on price in Westchester: the block itself is a cost driver. Wood-frame cities like Coral Gables or South Miami allow direct nailing into studs. Westchester requires masonry anchors and often a direct-mount system rated for the NOA, and that material and labor shows up in the line item. Our quotes are written, line-itemed, and fixed once we measure. Call (863) 862-5435 for a free in-home measure. You’ll get the real number before any contract shows up.
What Custom & Geometric Windows Costs in Westchester
Here’s the range most Westchester homeowners are looking at, before any grant or credit:
- Standard impact window (installed): $800 to $1,500 per unit
- Impact single-hung (installed): $900 to $1,800 per unit
- Custom geometric or arched opening (installed): $2,500 to $5,000 per opening
- Whole-home impact package: $8,000 to $25,000+ depending on opening count and shape mix
What moves the price in Westchester: the number of openings, how many are custom shapes, whether the walls are CBS block (almost all of them are), the design pressure rating mandated for your wind zone, and whether the opening requires a new header or structural lintel. The free in-home measure sets the real number. Call (863) 862-5435 to schedule yours.
Florida Pays You Back
Westchester homeowners have a few real financial offsets available. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, which can cover a meaningful slice of an impact window package. Florida exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit can return 30% of the product cost on qualifying units, up to $600 per year. And after a wind-mitigation inspection, typically $75 to $150, many Westchester homeowners see their windstorm premium credit average around 25% on the windstorm portion of the policy. We don’t set these numbers; the programs and your carrier do. But we’re happy to point you to the right documentation.
One comparison worth making: impact windows versus hurricane shutters. Shutters cost less upfront, but they only work if someone is home to hang the panels before the storm. Every hurricane season, someone in Westchester gets caught out. Impact windows are permanent protection, sealed and rated 365 days a year, with no panels in the garage and no schedule to remember. They also qualify for the Insurance and energy credits that shutters do not. That’s why most Westchester homeowners doing a full replacement choose impact glass.

FAQs - Custom & Geometric Windows in Westchester
No. Custom arched windows in Westchester require the Florida Product Approval to cover the exact geometric shape, not just a rectangular line item. The county reviews the NOA for the specific radius and glass configuration, and the anchors must meet a masonry spec for block walls. Get the shop drawing verified before fabrication. Call (863) 862-5435 before you order anything.
It changes the anchoring entirely. In a wood-frame house, a large picture window fastens directly to framed rough openings. In Westchester’s CBS block, every custom window needs a direct-mount masonry anchor system rated for the NOA and the design pressure of that opening. Block also means cutting a new opening is heavier work, often requiring a lintel or engineered header. We scope the structural piece before quoting. Call (863) 862-5435 for a free measure.
If you want your insurer to keep renewing the policy, yes. Jalousie windows are an automatic red flag on Miami-Dade wind mitigation reports, and many Westchester homeowners are finding their carrier will not credit or renew with them present. Converting a jalousie wall to a custom impact window with a laminated interlayer changes the wind mitigation picture for the whole property. We handle the permit, the inspection, and the paperwork. Call (863) 862-5435 and we’ll walk you through what your specific home needs.
Yes, on a south-facing or west-facing Westchester wall, a low-E insulated glass unit cuts solar heat gain measurably, and that shows up on the FPL bill. The original single-pane aluminum frames throughout Westchester’s ranch homes are thermal sieves, and replacing them with insulated impact glass is one of the most reliable energy upgrades a homeowner here can make. The federal 25C credit can return 30% of the product cost on qualifying units. Call (863) 862-5435 to see if your openings qualify.
Because Coral Gables has a large share of wood-frame construction, and Westchester is overwhelmingly solid CBS block. Anchoring a custom impact window into block requires a masonry anchor spec, a direct-mount system rated for the NOA, and often a new lintel or header. That material and labor is a real line item, and it’s the difference between a block install in Westchester and a frame install next door. Call (863) 862-5435 and we’ll show you the exact number for your walls, not a city average.
