AfterCustom Impact Windows in Westchester, FL
Custom impact windows in Westchester, FL are impact-rated window units built to non-standard shapes or sizes - Custom & Geometric Windows services like arches, octagons, trapezoids, radius tops, and oversized picture windows - that also meet Miami-Dade and Florida Building Code wind-load requirements. They protect your home during a hurricane, reduce energy bills year-round, and they don’t force you to board up or sacrifice the architectural details that make your house look like your house. At Winslow Windows & Doors, we’ve been fitting homes with custom impact windows since 2011, and Ed Winslow’s name is on every job we do.
If you’ve been told by a big-box installer that your arch window or oversized bay unit “can’t be done” in an impact-rated product, call us at (863) 251-5864 before you accept that answer. We work with manufacturers like ES Windows and ECO Window Systems that fabricate to spec - not to a catalog. Our parent service page, Custom & Geometric Windows in Westchester, gives a broader look at everything we do with non-standard shapes; this page focuses specifically on the impact-rated side of that work.

When You Need Custom Impact Windows
Not every Westchester homeowner is shopping for custom impact windows - but if any of the situations below sound familiar, this is almost certainly the right conversation to have.
- Your home has non-rectangular windows that still have standard glass. Arched transom windows, half-rounds above a front door, and angled clerestory units are common in Westchester’s older ranch-style and Mediterranean-revival homes. Standard glass in those openings puts your entire house at risk the moment a Category 1 storm sends debris airborne.
- You’re installing hurricane shutters on every window except the odd-shaped ones. Shutters don’t fit a custom arch cleanly. Impact glazing is the only practical storm-protection solution for irregular openings, and a home with one unprotected window is not a protected home.
- You’re renovating or adding square footage and want the new windows to match existing architecture. Westchester’s mix of 1960s through 1990s construction often includes original decorative windows that newer off-the-shelf units won’t replicate. We can match profile, color, and glass tint so the addition doesn’t read like an addition.
- Your current custom windows are fogged, cracked, or the seals have failed. Moisture infiltration between panes isn’t just an aesthetic problem in Westchester’s humidity. It means the insulating gas is gone, your energy bills are rising, and the unit is no longer performing as rated.
- You want to open up a wall with a large, impact-rated picture window or corner unit. Oversized openings require custom fabrication almost by definition. Done right, a floor-to-ceiling impact window can dramatically change how a room feels while still meeting code.
- Your insurance renewal flagged unprotected openings. Florida insurers have been increasingly specific about window protection documentation. Custom impact windows with a Miami-Dade Notice of Acceptance (NOA) give you the paperwork to back up the protection.
Our Custom Impact Windows Process
Custom work fails when someone guesses. Our process is built around measuring twice, ordering once, and showing up when we say we will.
-
Free On-Site Consultation and Measure
Ed Winslow or a senior member of our team comes to your Westchester home, looks at the actual openings, and talks through what you’re trying to accomplish. We measure every dimension - width, height, diagonal, reveal depth, wall thickness - because custom fabrication tolerates zero rounding. We also assess the rough opening condition and check whether any structural or framing work will be needed before installation.
-
Upfront Quote with Line-Item Pricing
You’ll receive a written quote that breaks down product cost, fabrication lead time, and installation labor as separate line items. No blended “project price” that hides where the money goes. If you’ve received a written estimate from another company, our free second opinion is available - bring it in and we’ll go through it line by line.
-
Custom Fabrication Order
We order your windows through manufacturers like ECO Window Systems or ES Windows that build to your exact specifications. Lead times for custom impact units typically run four to eight weeks depending on shape complexity and glass package. We’ll give you a realistic timeline upfront, not an optimistic one we’ll walk back later.
-
Pre-Installation Prep and Permit Coordination
Impact window replacements in Westchester require a Miami-Dade County permit. We handle the permit application, submit the product NOA documentation, and coordinate the inspection schedule. You don’t have to navigate the county building department yourself.
-
Installation by Background-Checked, Uniformed Technicians
Every technician who arrives at your door has passed a background check and arrives in a Winslow uniform. You’ll know who to expect before the truck pulls up. Installation includes removing the old unit, inspecting and repairing the rough opening if needed, setting and anchoring the new frame to impact specifications, applying proper flashing and sealant, and cleaning up completely before we leave.
-
Final Inspection and 36500-Day Done Right Sign-Off
After the county inspection clears, we do our own walkthrough with you. If anything is off - sealant line, hardware operation, glass clarity - we address it before we close the job. Every installation is backed by our 36500-Day Done Right Promise: if it’s not done right, we come back and make it right. That’s not a warranty card in a drawer. It’s Ed’s word.
Custom Impact Windows Pricing in Westchester
Custom impact windows cost more than standard-size impact units, and the range is wide because the variables are wide. Here’s an honest look at what affects your number in the Westchester market.
| Window Type / Scenario | Typical Installed Price Range |
|---|---|
| Custom arch or half-round transom (small, single unit) | $650 – $1,100 |
| Custom casement or awning, non-standard size | $800 – $1,600 per unit |
| Large custom picture window (oversized, single lite) | $1,400 – $3,200 |
| Geometric / polygon unit (octagon, trapezoid, etc.) | $900 – $2,200 per unit |
| Multi-unit custom combination (arch over casement pair, etc.) | $2,000 – $5,500+ |
| Full home with multiple custom openings | Quoted as a project - call for details |
What Moves the Price
- Shape complexity: A simple arch costs less to fabricate than a true polygon or compound-angle unit. More cuts, more labor in the factory, higher price.
- Glass package: Low-E coatings, laminated interlayers, tint, and impact-rated tempered or laminated glass all affect cost. Florida’s solar heat gain requirements mean most Westchester homeowners benefit from a low-E package anyway - it pays back in lower electric bills.
- Frame material and color: Standard white or bronze PVC costs less than custom-color or aluminum-clad frames. If you’re matching an existing trim color, expect a slight premium.
- Rough opening condition: Westchester homes from the 1970s and 1980s sometimes have wood rot or corroded framing around original window openings. We identify this during the measure visit - not after we’ve started demolition.
- Permit and inspection fees: Miami-Dade County permit fees vary by project value. We include an estimate in your quote so there’s no surprise line item at the end.

Why Westchester Homes Specifically Need Custom Impact Solutions
Westchester sits in unincorporated Miami-Dade County, which means it falls under the county’s wind-borne debris region requirements - some of the strictest in the state. Every window replacement here needs a product with a valid Miami-Dade NOA, and custom-fabricated units have to carry that NOA for the specific size and configuration being installed, not just for a “similar” size in the catalog.
The neighborhood’s housing stock adds another layer. A lot of Westchester’s homes were built between 1955 and 1985, a period when Geometric & Shaped Windows like arched entries, clerestory strips along rooflines, and jalousie windows were popular - though many have since been converted to fixed or casement units in non-standard rough openings. Those openings don’t match anything in a standard product line, which is exactly why working with a fabricator that builds to order matters here.
Westchester also sits close enough to Biscayne Bay and the Atlantic coast that storm surge and sustained wind speeds in a major hurricane event are serious concerns. A home with eight impact windows and one Arched & Curved Windows opening left unprotected over the front door has one unprotected arch over the front door. Storms don’t negotiate.
We’ve worked in the neighborhoods around Westchester long enough to know that the older the home, the more likely the window situation is going to be non-standard. Bird Road corridors, the streets running south toward Coral Terrace, the blocks near West Flagler - these are areas where we see Oversized Openings and other custom impact work regularly, and where off-the-shelf solutions consistently come up short.
Key Takeaways
- Custom impact windows are impact-rated units built to non-standard shapes or sizes - the solution when catalog products don’t fit your opening or your architecture.
- In Westchester, every replacement window needs a Miami-Dade NOA. Custom units need NOA coverage for the exact configuration being installed.
- Installed prices typically range from $650 for a small transom to $5,500 or more for a multi-unit combination. Shape complexity, glass package, and rough opening condition are the main cost drivers.
- Winslow handles permit coordination, county inspections, and fabrication lead-time management - you don’t have to track those moving parts yourself.
- Every job is covered by our 36500-Day Done Right Promise. If it’s not right, we fix it. That’s the promise Ed makes on every project.
- Seniors and veterans receive a permanent 10% discount. Estimates are always free.
FAQs – Custom Impact Windows in Westchester
How long does it take to get custom impact windows installed in Westchester?
From the time you approve your quote, expect four to eight weeks for fabrication plus one to three days for installation, depending on how many units and the complexity of the opening. Permit processing in Miami-Dade typically adds one to three weeks to the schedule, and we submit the permit application as soon as the order is placed. If you have a specific date pressure – a closing, a renovation deadline, an insurance requirement – tell us on the first call and we’ll tell you honestly whether we can hit it. Call (863) 251-5864 for a timeline specific to your project.
Do custom impact windows cost significantly more than standard impact windows?
Yes, custom impact windows cost more than catalog-size units, typically 20% to 50% more depending on shape and size. The premium comes from factory fabrication time and the specialized tooling required for non-standard cuts. That said, for an opening that doesn’t accept a standard unit, a custom impact window isn’t a luxury – it’s the only code-compliant option. In Westchester’s storm environment, leaving a non-standard opening with standard glass to save money on fabrication is a false economy. Call us at (863) 251-5864 for a free estimate so you’re working from real numbers, not guesses.
Can any window shape be made impact-rated?
Almost all fixed (non-operable) shapes can be fabricated as impact-rated units, including true arches, octagons, trapezoids, triangles, and ellipses. Operable shapes – those that open and close – have more constraints because the hardware and weather-stripping systems used for impact rating are harder to engineer around irregular geometry. We’ll tell you at the measure visit exactly what’s possible for your specific opening. Manufacturers like ES Windows and ECO Window Systems have broader custom capability than most national brands, which is part of why we work with them.
Does my homeowner’s insurance in Westchester give me credit for custom impact windows?
Florida homeowners insurance carriers do give wind-mitigation credits for impact-rated windows with a Miami-Dade NOA, and custom impact windows qualify the same as standard ones as long as the product carries the proper certification for the installed configuration. After installation, you’ll need a wind mitigation inspection by a licensed inspector – a separate step from the county permit inspection. We can point you toward inspectors who work in the Westchester area. The credits often offset a meaningful portion of your annual premium, which changes the math on what the windows actually cost over time.
