AfterCustom Impact Windows in Coral Gables, FL
Custom impact windows in Coral Gables are hurricane-rated glass units built to non-standard shapes or sizes – arched tops, wide picture frames, trapezoids, and other configurations that standard off-the-shelf windows simply can’t fill. Most homes in Coral Gables that need these windows are also sitting in a high-velocity hurricane zone, so impact protection isn’t optional; it’s a code requirement and a practical necessity. At Winslow Windows & Doors, we’ve been measuring, ordering, and installing custom impact windows in Coral Gables since 2011, and Ed Winslow’s name is on every job we do.
If you’re dealing with an unusual opening that no catalog window fits, or you’re replacing a decorative feature that also needs to meet Miami-Dade NOA standards, this page walks through exactly what to expect – from the first measurement to the final inspection sign-off. You can also explore our full range of shaped and specialty glass on our Custom & Geometric Windows in Coral Gables parent page. Ready to talk specifics?

When You Need Custom Impact Windows
Not every Coral Gables home fits a standard window catalog. Here are the situations where custom impact windows are the right call:
- Arched or radius-top openings in older Mediterranean Revival homes. Coral Gables has an unusually high concentration of 1920s and 1930s Mediterranean Revival architecture along streets like Alhambra Circle and Coral Way. Those arched openings are beautiful – and they require a custom-fabricated impact unit to meet today’s wind-load codes.
- Oversized picture or panoramic openings. Wide-view frames that exceed standard width limits (typically anything wider than 72 inches) need to be custom-ordered. We regularly fit expansive bay-facing windows in properties near the Coral Gables waterways where homeowners want maximum glass, minimum frame.
- Replacement after storm or impact damage to a non-standard unit. If a previous hurricane or flying debris took out a shaped window, you can’t walk into a home improvement store and find a matching replacement. A custom impact order is the only path that restores both the look and the code-compliant protection.
- New construction or addition with architect-specified geometry. Custom floor plans in Coral Gables developments often call for trapezoid, pentagon, or triangle windows to match a roofline or stairwell wall. We work directly from architectural drawings so the finished unit matches the spec exactly.
- HOA or City of Coral Gables design guidelines requiring specific profiles. The city’s historic preservation rules and many Coral Gables HOAs are specific about the visual profile of window frames and glass tint. A custom impact window lets you meet impact code without sacrificing the approved aesthetic.
- Energy inefficiency from aging or improperly fitted specialty windows. Non-impact custom windows installed before 2000 are often single-pane or poorly sealed at irregular edges. Replacing them with a properly fitted, laminated impact unit eliminates the air infiltration and UV gain that drives up cooling bills in South Florida’s heat.
Our Custom Impact Windows Process
Custom work takes more steps than a standard swap, and that’s a good thing – shortcuts in measurement or fabrication are what create gaps, callbacks, and failed inspections. Here’s how we handle every custom impact window project in Coral Gables:
- On-site consultation and precise field measurement. Ed Winslow or one of our background-checked, uniformed technicians comes to your home and measures the opening in multiple points. Custom shapes require more measurement points than rectangles – an arch, for example, needs its radius recorded accurately at several heights. We also assess the surrounding wall construction (CBS, wood frame, or hybrid) because the rough opening and anchor requirements differ. No charge for this visit inside our home county.
- Product selection and NOA verification. We work with brands including CGI, CWS, and ES Windows for custom impact fabrication. Each product we specify carries a Miami-Dade Notice of Acceptance (NOA) relevant to the window’s design pressure rating. We match the product’s rated DP to what your specific opening demands based on Coral Gables’ wind exposure category. We present you with options – frame color, glass type (clear, low-e, tinted), and hardware finish – with upfront pricing before anything is ordered.
- Permit filing with the City of Coral Gables. Custom impact windows in Coral Gables require a building permit. We handle the application, submit the product approval documentation, and coordinate the inspection schedule. You don’t need to manage paperwork or follow up with the building department – we track the permit status and keep you informed at each stage.
- Factory fabrication and delivery coordination. Custom units are built to order. Lead times vary by product and complexity, but we give you a realistic timeframe at the point of order – not a vague “several weeks.” We track the order and confirm the delivery window with you so you can plan accordingly.
- Professional installation. Our installation crew follows manufacturer specs for anchorage spacing, sealant application, and flashing – details that matter for both the wind-load performance and the long-term water tightness. For high-tension components in any window system, our technicians handle all mechanical work; we don’t leave structural fastening or frame anchoring to homeowners, and we’d caution against any DIY attempt on impact-rated units where improper installation can void the NOA and create a genuine safety hazard in a storm.
- Final inspection and walkthrough. After the city inspector signs off, we walk you through the completed installation – showing you the operation of any operable sash, confirming the sealant lines, and documenting the permit closure. If anything isn’t right, the Done Right Promise means we come back and make it right. No arguments, no extra charges.
Custom Impact Windows Pricing in Coral Gables
Geometric & Shaped Windows in Coral Gables typically cost more per unit than standard-size impact replacements, because every unit is fabricated to order and the geometry adds complexity to both the manufacturing and the installation. Below are honest market ranges based on what we see in Coral Gables projects.
| Window Type / Scenario | Typical Installed Cost Range |
|---|---|
| Small custom fixed impact window (under 10 sq ft, simple shape) | $900 – $1,500 per unit |
| Medium arched or radius-top impact window (10-20 sq ft) | $1,500 – $2,800 per unit |
| Large panoramic or picture impact window (20-40 sq ft) | $2,500 – $4,500 per unit |
| Complex polygon or multi-angle custom impact unit | $2,000 – $5,000+ per unit |
| Permit and inspection fees (City of Coral Gables) | $150 – $400 depending on project scope |
What drives the cost up or down:
- Glass type: Low-e laminated glass carries a premium over standard clear laminate, but the energy savings in Coral Gables’ year-round sun typically pay back the difference within a few years.
- Frame material and color: Standard white or bronze aluminum is the most common and the most affordable. Custom powder-coat colors or wood-interior cladding add to the unit cost.
- Design pressure rating required: Coastal and waterfront properties near the Coral Gables waterway system sometimes need higher DP-rated units, which means heavier laminate and stronger frame profiles.
- Wall construction: CBS (concrete block) walls need anchor systems different from wood-frame walls, and the labor to core into CBS properly takes more time.
- Number of units: Multi-window projects on the same visit reduce the per-unit installation cost because mobilization and permitting are shared across the job.
We don’t give ballpark numbers over the phone without seeing the opening – the geometry matters too much. What we do offer is a free, no-obligation on-site estimate with written, itemized pricing before you commit to anything. If you’ve already received a written quote from another company, we’ll give you a free second opinion on it. And if your project total is over $200 in repairs, you get $40 off.

Why Coral Gables Homeowners Choose Winslow
There’s no shortage of window companies in South Florida. Most of them will give you a price and hand you off to a crew you’ve never met. Winslow Windows & Doors works differently, and it’s not a slogan – it’s how we’ve stayed in business since 2011 in a market where homeowners talk to each other.
Ed Winslow is a known name in this community. He’s not a regional manager three states away; he’s the person who started this company and still backs every installation with the Done Right Promise. That’s not a limited-time warranty – it’s a permanent standard of accountability that no national chain can match because no national chain has an owner whose reputation is literally on the line in the same neighborhoods where the work is done.
When you call us at any hour – 2 a.m. before a storm, Sunday morning with a failed sash – a real person picks up. We’ve been doing that since the beginning, and we’re not going to stop. Every technician who shows up at your door is background-checked and arrives in uniform; you know exactly who’s coming before the truck pulls into the driveway.
We’re also authorized installers for CGI, CWS, ES Windows, and ECO Window Systems, among others. That authorization matters for custom work because it means the manufacturer recognizes us as qualified to install their product in ways that preserve the NOA and the product warranty. A non-authorized installer who fits a CGI custom unit can inadvertently void the very protection you paid for.
And there are no hidden fees. Upfront pricing means the number we write down before we start is the number on your invoice when we finish. If something unexpected comes up mid-job – and with older Coral Gables homes, it occasionally does – we tell you before we proceed, not after.

FAQs – Custom Impact Windows in Coral Gables
Do custom impact windows in Coral Gables require a permit?
Yes, custom impact window installations in Coral Gables require a building permit from the city’s Building and Zoning Department. Every window we install must be accompanied by the product’s Miami-Dade Notice of Acceptance and a site-specific permit. We file all of that paperwork for you and track the permit through to final inspection. You don’t need to visit the building department or manage any of the coordination yourself. Call (904) 478-8983 and we’ll walk you through the timeline for your specific project.
How much do custom impact windows cost in Coral Gables?
Installed costs in Coral Gables generally run $900 to $1,500 for small fixed custom units and $2,500 to $4,500 or more for Oversized Openings or complex polygon shapes. The biggest cost drivers are glass square footage, design pressure rating needed for your specific location, frame profile, and wall construction type. An arched Mediterranean Revival window on Alhambra Circle, for example, will cost more to fabricate and install than a simple oversized rectangle – but we give you exact numbers in writing before any work begins. Get a free estimate by calling (904) 478-8983.
How long does it take to get custom impact windows installed?
From signed agreement to completed installation, most custom impact window projects in Coral Gables take four to eight weeks. The permit application typically takes one to two weeks for city review. Custom fabrication adds another two to five weeks depending on the brand and complexity. Once the unit arrives and the permit is active, installation itself usually takes one to two days for a typical residential project. We give you a specific timeline at the point of order – not a vague estimate – and we keep you updated if anything changes.
Can I replace just one custom impact window, or do I need to do the whole house?
You can absolutely replace a single custom impact window without replacing every other window in the home. There’s no code requirement forcing a whole-house replacement when only one opening needs attention. That said, if your other windows are original single-pane units from the 1970s or 1980s, a phased replacement plan often makes financial and practical sense – you spread the cost while systematically bringing each opening up to current Miami-Dade standards. We’re glad to assess the full picture and give you honest input, with no pressure to do more than you’re ready for. Call (904) 478-8983 to set up a free on-site consultation.
