Fast, Reliable Custom & Geometric Windows Across Westchester
Custom and geometric window work in Westchester is not a generic swap. It is a code-governed, material-sensitive job where the wrong glass package gets rejected at inspection and the wrong frame coating pits within five years. We’re Winslow Windows & Doors, and we’ve been replacing, re-glazing, and building custom openings in Miami-Dade’s HVHZ since 2011. Ed Winslow’s name is on the door, and our crews know exactly what a Westchester CBS ranch needs before the first measurement is taken.

Why Winslow Windows & Doors Is Westchester’s Preferred Custom & Geometric Windows Company
Westchester homeowners call us because we answer the phone. A live person, 24 hours a day, seven days a week. No voicemail loop, no ticket number. When you call about an arched picture window that failed a permit inspection on SW 16th Street, you talk to someone who knows what an NOA sticker is.
Our reputation in Westchester rests on the jobs we’ve done near Tropical Park, along Coral Way, and in the Bird Lakes and Century Park pockets. Every technician who pulls up to your house is background-checked and in uniform. You know who is walking through your gate before the truck door opens. That matters in a neighborhood where homeowners have been burned by out-of-county crews showing up with Florida statewide approval stickers that Miami-Dade rejects on sight.
We are the locally owned, owner-operated alternative to the faceless chains. Ed Winslow has published the company’s address and license number. We don’t hide behind a call center in another state. We’re the Westchester window contractor who shows up when we say we will, with products that pass inspection the first time.
Our Custom & Geometric Windows Services in Westchester
Every Custom & Geometric Windows job we take in Westchester starts with the same question: what shape, what glass, and will it carry a current Miami-Dade NOA? From there, we handle the full scope.
Custom Impact Windows
A custom impact window in Westchester must meet HVHZ wind-load requirements and carry a product certification that exists nowhere else in the country. We specify laminated glass interlayers matched to the exact NOA number on file with Miami-Dade County, then build the frame to match. No off-the-shelf substitute. No reusing a grandfathered single-pane assembly on a permitted opening. The result is a window that passes inspection and holds its design pressure rating for decades, not seasons.

Geometric & Shaped Windows
Triangles, trapezoids, pentagons, angled bays. Westchester’s 1950s and 1960s ranch homes have original geometric openings that were never glazed with impact-rated units. Many still hold single-pane louvered glass behind then-modern frames. We measure, template, and order custom geometric assemblies through our authorized lineup, including ECO Window Systems and Mr-Glass, with laminated glass and reinforced frames matched to the opening’s wind zone and floor height. The inspector will verify the glazing label against the approved NOA. We make sure it matches before the unit ever arrives.

Arched & Curved Windows
Arched picture windows on Westchester CBS homes are common and commonly non-compliant. Many are original to the house, with unlaminated glass and no NOA documentation. Replacing one requires a custom radius unit, often a PGT or Mr-Glass product, ordered to the exact arc. We re-glaze these openings with impact-rated laminated units, match the radius to within an eighth of an inch, and handle the structural anchoring the inspector checks. In Bird Lakes, we replaced three jalousies and an arched picture window on a 1960s CBS ranch. The inspector flagged the arch immediately for missing NOA. We re-glazed the opening with a PGT custom radius impact-rated unit, matched the laminated glass interlayer to the approved NOA number, and passed the HVHZ inspection the same week.

Oversized Openings
When a Westchester homeowner wants to open a wall into the backyard or replace a wall of original jalousies with a fixed impact picture window, the structural question comes first. A 1960s CBS home has concrete tie beams and lintels that determine what can be opened without a structural header change. We work with Miami-Dade permitting on every oversized job, pull the permit, and install the reinforced frame, heavy glass, and anchoring the HVHZ requires. Large custom openings run $2,500 to $5,000 installed depending on width, glass package, and whether a header modification is needed.

Trusted Brands We Service in Westchester
We are an authorized installer for a short, deliberate list of brands, and we don’t touch products outside that lineup. For Westchester custom and geometric work, we regularly specify ECO Window Systems for shaped and radius units, Mr-Glass for oversized impact fixed windows, and Therma-Tru for door assemblies that must match the glazing package on an adjacent opening. Because our crews work Westchester every week, we order directly through our distributor network with current NOA documentation attached to every unit. That means faster turnaround when a homeowner needs a replacement ordered, and fewer surprises at the county inspection.
Common Custom & Geometric Windows Problems We See in Westchester Homes
- Flatly non-compliant original jalousies. Westchester’s residential core is almost entirely 1950s to 1970s one-story CBS ranch homes, and many still have original single-pane aluminum jalousie windows. They fail catastrophic under HVHZ wind loads and leak conditioned air through louver joints all year, accelerating frame corrosion in Westchester’s 70% plus humidity. Any permit pull on these openings triggers full impact replacement.
- Statewide approval stickers that Miami-Dade rejects. Custom shaped windows ordered with Florida Product Approval but no Miami-Dade NOA get flagged at inspection. The product gets rejected, and the homeowner pays for a tear-out and reorder. We see this most often when an out-of-county crew has been on the job first.
- Salt-corrupted aluminum frames on geometric windows. Westchester sits roughly 10 miles from Biscayne Bay. Salt-laden air pits aluminum frame coatings and breaks the sealant bond within 5 to 7 years, leaving cloudy insulated glass units and water-stained jambs. A properly specified marine-grade finish or alternative frame system extends that service life considerably.
- Oversized arched replacements with no radius match. An arched opening from a 1960s CBS home needs a custom radius unit, not a squared-off retrofit. Ordering the wrong geometry wastes four to six weeks of fabrication time and delays the close-out inspection. We template the arc on site before ordering.
Pricing for Custom & Geometric Windows in Westchester, FL
Custom impact windows in Westchester generally run $800 to $1,500 per installed unit. A custom impact single-hung lands at $900 to $1,800. Large or custom arched openings run $2,500 to $5,000 installed, depending on span, glass package, and whether a concrete header modification is needed. Whole-home packages in Westchester, where a 1950s or 1960s ranch goes from jalousies to full impact glass across a dozen or more openings, range from $8,000 to $25,000 and up. What moves the price here: opening count, wind zone, floor height exposure, frame material, and whether the county requires an NOA-specific glazing package. Call (850) 721-1218 for a free in-home measure and a written quote. No change orders. The price on the estimate is the price on the invoice.
What Custom & Geometric Windows Costs in Westchester
Here is the honest math we walk every Westchester homeowner through. A standard impact-rated single window installed is $800 to $1,500. If you want a single-hung impact unit, budget $900 to $1,800. A big custom shaped or arched opening, the kind common on 1960s CBS ranch fronts, is $2,500 to $5,000. A whole-home package on a Westchester jalousie conversion, replacing every opening with impact-rated custom or standard units, starts around $8,000 and can reach $25,000 or more on larger homes with oversized glass. Frame material matters: aluminum with a marine-grade finish costs more upfront than inland-spec aluminum but resists Biscayne Bay salt pitting far longer. Floor height and exposure to wind loads move the required design pressure, which changes glass thickness and lamination. We give you the line-item price before any work begins, and we stand behind it.
Florida Pays You Back
The incentive stack in Florida is real, and Westchester homeowners should claim what they qualify for. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades on the primary residence. Florida exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit covers 30% of product cost, up to $600 per year on qualifying units. And after a wind-mitigation inspection, which runs $75 to $150, many carriers apply a windstorm-premium credit averaging around 25% on the windstorm portion of the policy. We can’t guarantee any of these numbers, because programs and insurance carriers set the final figures, but we’ll point you to the current application processes and documentation. Impact windows beat hurricane shutters in one permanent way: you never have to find the panels, carry them out in a storm, or fight rusted tracks at 2 a.m. The protection is already in the opening.
Every custom or geometric window we install in Westchester carries a current Miami-Dade NOA or Florida Product Approval number, matched to the exact configuration and design pressure of the opening. We never spec above the required rating and never list a pressure rating higher than the tested assembly allows. HVHZ compliance is a county requirement here, not a sales line.
Salt air near Westchester decides the materials, not the schedule. Painted steel fasteners and inland-spec aluminum frames corrode early in this environment, same as roofing fasteners and patio railings do. What we specify instead: stainless or hot-dip galvanized hardware, marine-grade frame finishes, and sealed joints that hold their bond in 70% plus humidity. The cheap inland spec saves money on day one and costs more within a decade because the frames pit, the seals fail, and the insulated glass units cloud. The coastal spec costs more upfront and lasts like it should. We build the second one.

FAQs - Custom & Geometric Windows in Westchester
Because Westchester sits entirely within Miami-Dade County’s High Velocity Hurricane Zone, the strictest wind-load jurisdiction in the United States. Every window, including a single arched unit, must carry a Miami-Dade County Notice of Acceptance, a certification that does not exist in any other U.S. county. Florida statewide Product Approval is not sufficient here. The inspector physically verifies the glazing label against the NOA number before signing off. Call (850) 721-1218 and we’ll check your existing glass documentation for free.
Legally, once a permit is pulled in Westchester, any opening being touched must be brought to current HVHZ impact compliance. The original single-pane jalousies are flatly non-compliant and cannot be re-glazed to meet code. You can phase the work, replacing openings one permit cycle at a time, but you cannot legally keep a non-compliant jalousie in a permitted replacement scope. We’ll help you sequence the job so it fits your budget without triggering a county flag on the untouched openings.
Salt air does not reduce the design pressure rating itself, but it degrades the aluminum frame and sealant bond that protects the glazing. Within 5 to 7 years, untreated aluminum frames on geometric windows pit, the sealant releases, and water intrusion compromises the insulated glass unit. Once the frame coating fails, the opening no longer performs to its tested rating. That is why we specify marine-grade finishes and sealed joints on Westchester custom work. The rating stays accurate only if the assembly stays intact.
It depends on the existing opening and the concrete tie beam above it. You can typically replace an existing jalousie or picture window bank with a larger fixed impact window if the new width stays within the existing lintel span and the original header is structurally sound. Widening the opening beyond the original concrete lintel requires a structural engineer’s review, a new header, and a separate permit scope. We assess this on site during the free measure, before you spend a dollar on glass.
Yes, as long as each custom unit carries a valid Miami-Dade NOA and is installed to the tested assembly, it qualifies for the same wind-mitigation credits on a standard uniform inspection. The shape of the window does not reduce the credit; the documentation and the installation do. We provide the NOA paperwork for every opening on completion, so your wind-mitigation inspector has exactly what the carrier needs. Call (850) 721-1218 for a free quote and documentation walkthrough.
