AfterFast, Reliable Custom & Geometric Windows Across Westchester
Custom and geometric windows in Westchester aren’t a side project for us. They’re the reason homeowners call after two or three other companies have said “we don’t do that shape.” A fixed arch over a picture window, a radius corner on a bedroom unit, a full gable of trapezoids facing Bird Road: these openings live in 1950s CBS ranch homes that sit inside Miami-Dade County’s High Velocity Hurricane Zone. Every one of them needs a Miami-Dade NOA product approval that most national chains don’t stock and won’t chase down. We do, because Ed Winslow’s name is on the door. Call (844) 901-4551 and you’ll reach a live person who can talk through your opening, your street, and your permit reality before you ever sign anything.
Why Winslow Windows & Doors Is Westchester’s Preferred Custom & Geometric Windows Company
Westchester is built tight. The lots off Coral Way and Bird Road are 50 feet wide when they’re wide, the CBS walls run to the property line, and a neighbor’s bedroom window often sits eight feet from your own. Work on a home like this requires staging discipline most installers never develop: material goes on the street or in a single driveway, cut lines follow the masonry, and party-wall notice happens before the first hammer fall, not after a complaint. We know the rhythm of these blocks because we work them constantly. The jalousie windows in a 1958 ranch on SW 16th Street create the same NOA replacement trigger as the one on SW 92nd Avenue, and we’ve pulled permits for both.
Our Westchester customers consistently say two things: the crew was on time, and the property looked cleaner after we left, not worse. That matters when your staging area is the sidewalk and your neighbor’s carport abuts your side yard. The city does not negotiate on HVHZ compliance, and neither do we. Every custom or geometric unit we install carries a Miami-Dade Notice of Acceptance verified against the specific design pressure for that wall zone, that opening height, and that floor elevation. No exceptions, no “it’ll probably pass.”
Key Takeaways for Westchester Homeowners:
- Every replacement window in Westchester must carry a Miami-Dade NOA. That’s non-negotiable code, not a preference.
- Jalousie windows cannot be grandfathered. Any permit that touches that opening forces a full-frame impact replacement.
- Tight lots mean real staging constraints. A quote that ignores parking and access will change once the crew arrives. Ours doesn’t.
- Custom shapes take 4-6 weeks to fabricate. We order on permit approval, not after the opening is torn out.
Our Custom & Geometric Windows Services in Westchester
As the Custom & Geometric Windows team at Winslow, we handle the shapes other shops scratch their heads at. Here’s what that means on a Westchester ranch home with masonry openings and no nail fins.
Custom Impact Windows
A custom impact window in Westchester starts with the opening, not a catalog. We measure the existing CBS buck, check the wall zone per your permit drawings, and order a unit whose Miami-Dade NOA matches the design pressure that specific elevation demands. For most 1950s and 1960s ranches, that’s a laminated glass unit in an aluminum or vinyl frame that anchors to the block rather than nailing to a wood buck. The result is a window that holds under wind-driven rain and debris without changing the sightlines your home was built around.
Geometric & Shaped Windows
Trapezoids, triangles, octagons, radius corners, parallelograms: these shapes are common in Westchester’s mid-century builds, especially over front doors and in gable ends. Each one is ordered as a fixed impact unit matched to the exact angle and leg length of the opening. We template every geometric opening in person because a 1/8-inch error on a 45-degree leg means a unit that won’t seat in the buck, and on a tight Westchester lot, you don’t get a second staging day for free.
Arched & Curved Windows
True radius and segment arched windows show up frequently on Westchester’s 1970s split-level and ranch facades, particularly along the wider lots off SW 67th Avenue. The challenge is that a curved impact unit is fabricated to a specific radius and chord width, and it must still carry a NOA that covers the glass area and the frame anchoring. We’ve replaced arched aluminum originals with PGT fixed arch tops over operable awning units, and the difference in both curb appeal and wind performance is immediate.
Oversized Openings
When a Westchester homeowner opens a Florida room wall or converts a living-room picture window into a full impact feature, the opening is often 6 to 10 feet wide. That’s an oversized unit requiring a reinforced header, buck-anchored frame, and glass that meets large-missile impact standards. We engineer these with the manufacturer’s product approval in hand before the permit gets filed, because no building department in Miami-Dade releases an oversized impact window to framing inspection on a promise.

Trusted Brands We Service in Westchester
We’re an authorized installer for PGT, CGI, CWS, and ES Windows, which matters when the unit has to match a specific NOA number and a specific aesthetic. For custom and geometric work on Westchester homes, PGT and CGI do the heavy lifting: true radius tops from PGT’s custom division, oversized fixed trapezoids from CGI’s product approval library. Because we order directly through these manufacturers and not through a middleman, changes and fabrication updates are faster, which matters when your geometric window is a 5-week lead time and your permit is ready now. No parts bin guessing. No “similar shape” substitutions.
Common Custom & Geometric Windows Problems We See in Westchester Homes
- Jalousie replacement without NOA paperwork. A homeowner replaces a louvered jalousie with a custom geometric window and the installer reuses the old buck and anchors. The HVHZ inspection fails on the anchor pattern and the lack of a product approval for the exact design pressure. We see this repeatedly on pre-1993 CBS homes across 33144.
- Arched or oversized impact units with the wrong NOA. A custom arch is ordered with a NOA that covers a lower design pressure than the wall zone on that specific dense lot, especially on side elevations that sit close to neighboring structures. The fix is a reorder, not a field modification.
- Non-impact custom shapes over Florida rooms. The no-grandfathering rule in Miami-Dade means any permit touching a Florida room window forces impact compliance. Installing a non-impact shaped unit to save money creates a stop-work order and a double purchase.
- UV-degraded sealant and oxidized frames around original shaped windows. Westchester’s year-round humidity and intense sun eat through perimeter sealant on arched and radius frames faster than almost anywhere else in Florida. By the time a homeowner notices, the frame is often too degraded to salvage.
Pricing for Custom & Geometric Windows in Westchester, FL
You want a number before you pick up the phone. Here are the honest ranges for Westchester work, including installation and permit-ready product approvals.
| Window Type | Typical Installed Price per Unit (Westchester) |
|---|---|
| Standard impact single-hung | $900–$1,800 |
| Custom fixed geometric (triangle, trapezoid) | $1,200–$2,800 |
| Arched or radius fixed impact | $1,800–$3,500 |
| Oversized opening (6-10 ft impact unit) | $2,500–$5,000 |
| Whole-home custom geometric package (8+ openings) | $8,000–$25,000+ |
The wildcard in Westchester is access. A geometric window on the front elevation of a house off SW 8th Street with a driveway costs less to stage than the same unit on a rear Florida room where the crew carries glass through a 36-inch gate and stages on the sidewalk. Frame material moves the numbers too: aluminum holds tighter tolerances on custom shapes but costs more than vinyl. We give a written, line-item quote after an in-home measure, and it stays exactly what it says. Call (844) 901-4551 to schedule yours.
What Custom & Geometric Windows Costs in Westchester
A typical impact window in Westchester runs $800 to $1,500 installed. Impact single-hungs start around $900 and climb to $1,800 for larger openings or elevated floors. Custom geometric shapes run higher because each unit is a one-off fabrication with its own Miami-Dade NOA, not a stock SKU. Expect $1,200 to $2,800 for a fixed triangle or trapezoid, $1,800 to $3,500 for a true radius arch, and $2,500 to $5,000 for an oversized opening that spans six feet or more. Whole-home packages across an entire CBS ranch commonly land between $8,000 and $25,000 depending on opening count and glass type. What moves the price in Westchester specifically: wall zone design pressure on dense lots, floor height, frame material, and whether the opening is front-elevation accessible or a rear Florida room with tight staging. We measure, we quote, and the number holds. No change orders on access we already saw.
Florida Pays You Back
Westchester homeowners can stack several programs on top of a custom impact window purchase. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and impact windows and doors are the classic qualifying improvement. Florida also exempts impact-resistant windows and doors from sales tax. On the federal side, the 25C energy credit covers 30% of the product cost, up to $600 per year on qualifying Low-E units. After installation, a wind-mitigation inspection ($75 to $150) can unlock windstorm premium credits that many Westchester homeowners report averaging around 25% on the windstorm portion of their policy. Programs change, and your carrier sets the final credit, so we never quote a savings number as a promise. What we do promise: every unit we install is documented for inspection so the paperwork doesn’t get in the way of your credit.
Impact windows vs. hurricane shutters: Shutters protect you only when someone is home to hang them, and they do nothing for UV, noise, or energy between storms. An impact window in Westchester sits in the wall permanently, which matters on a street where an empty house with unshuttered jalousies is the first one to lose water through every opening. Shutters also don’t solve the jalousie problem. An impact unit does.
Working on a Tight Westchester Lot: Staging, Permits, and Neighbors
Westchester’s entire housing stock of pre-1993 CBS ranch homes lies inside Miami-Dade’s High Velocity Hurricane Zone. That one fact changes everything about how a custom geometric window gets ordered, permitted, and installed here compared to, say, a wood-frame house in Broward. Every replacement unit must carry a Miami-Dade NOA, a product approval stricter than anything Broward County requires. That’s the reason full impact replacement, not repair, is the standard job on these blocks. When a 1958 ranch on SW 92nd Avenue needs a fixed arch over the front door, there is no “just patch the frame” option. The old unit comes out, the opening gets buck-anchored, and the new impact glass goes in to meet HVHZ design pressure.
On a 1950s ranch just off Bird Road, we pulled the original jalousie and flanged aluminum openings from a bedroom and replaced them with custom impact-rated PGT casements and a fixed geometric arch. The masonry openings had no nail fin, so our crew buck-anchored every jamb, then sealed with large-missile-rated laminated glass to meet HVHZ design pressure. All of it happened while staging on the street and coordinating party-wall notice with the adjoining CBS wall, because the neighbor’s window was close enough to reach out and touch. That’s a standard Westchester install for us.
Density forces a different quote. Where a Broward install crew can back a truck into a yard, our Westchester crews plan for street staging, hand-carry paths through side gates, and work-hour limits that respect the neighbors. We pull the permit, schedule inspections, and keep the site clean enough that nobody on either side of you complains about the contractor. That discipline is part of the price, and it’s part of why homeowners off Coral Way and Flagler keep calling us back.

FAQs — Custom & Geometric Windows in Westchester
No. Under Miami-Dade’s HVHZ code, jalousie windows cannot be made NOA-compliant and there is no grandfathering. The moment a permit is pulled for any window work, every jalousie opening in the permit scope must be replaced with full-frame impact units. You can phase the work, but you cannot keep a jalousie permanently if the opening is touched by a permit. Call (844) 901-4551 and we’ll map out a phased plan that fits your budget.
It costs more because Miami-Dade County requires a NOA product approval with a design pressure rating matched to your specific wall zone and elevation, and many manufacturers charge for the engineering file that proves the unit meets HVHZ standards. Broward does not enforce the same product approval depth. The glass, frame, anchoring, and paperwork are all heavier in Westchester. That’s the price of living where the wind actually hits.
Yes. A fixed window is still a fenestration opening, and in Westchester’s HVHZ it must meet the same impact and design pressure requirements as an operable unit. The NOA covers the glass makeup, frame, and anchoring system, not just the hinge hardware. Installing a non-approved fixed arch invites an inspection failure and a reorder, which doubles your lead time. Call (844) 901-4551 before you order anything shaped.
It affects access, staging, and sometimes equipment. If we can’t get the glass to the opening without hand-carrying it through a 36-inch gate and along a narrow side yard, that labor shows up in the quote. If we need a boom or special lift because the opening is on a second story with no driveway access, that shows up too. We include these costs on the front end, so the written estimate you sign is the number you pay. No surprise access fees on install day.
Yes, in most cases. After installation, a wind-mitigation inspection documents the impact-rated openings and the anchoring. Most Westchester homeowners see a reduction on the windstorm portion of their premium once the inspection report reaches the carrier. How much depends on your insurer, your home’s other mitigation features, and your policy. We provide the installation documentation inspectors need to verify compliance.
