AfterCustom Impact Windows in Miami Beach, FL
Custom impact windows in Miami Beach are impact-rated, hurricane-code-compliant windows built to non-standard shapes or dimensions – arched, trapezoidal, circular, or simply oversized – and installed to meet Miami-Dade County’s strict Notice of Acceptance (NOA) requirements. Most homes in Miami Beach that were built before 2002 still carry older windows that won’t pass today’s wind-load ratings, and if your openings fall outside the dimensions that stock windows cover, a custom impact unit is the only path to full code compliance. At Winslow Windows & Doors, we’ve been doing exactly this work since 2011, and Ed Winslow signs off on every project personally.
If you’ve been quoted an off-the-shelf impact window that “almost fits,” hang up. An improperly sized impact window voids the product’s NOA, and your insurer will know it the moment you file a storm claim. Call us at (863) 656-0462 – a live person answers around the clock – and let’s talk about what your openings actually need. This page sits under our broader Custom & Geometric Windows in Miami Beach service, which covers the full range of non-standard window solutions we offer across the island.
When You Need Custom Impact Windows
Not every Miami Beach home fits the mold – and neither should the windows protecting it. Here are the situations we see most often:
- Pre-2002 construction with original single-pane windows. Homes in neighborhoods like Sunset Islands and North Bay Road were built decades before Miami-Dade’s post-Andrew codes existed. Those original windows – even if they look solid – carry no wind-load rating that today’s insurers will accept.
- Arched or transom openings that stock sizes don’t cover. Mediterranean Revival and Art Deco architecture along Collins Avenue and the Flamingo neighborhood frequently features arched transoms and radius-top openings. Off-the-shelf impact windows simply don’t come in those shapes.
- Insurance renewals tied to wind mitigation upgrades. Citizens Property Insurance and most private carriers writing policies in Miami Beach now require a wind mitigation inspection. If your report flags non-impact glazing, your premium spikes or your coverage is non-renewed. Custom impact windows are the fix.
- Existing impact windows that are fogged, cracked, or delaminated. Impact glass is laminated – the inner PVB layer can delaminate after years of South Florida UV exposure, creating that milky haze you see in older units. A delaminated window is no longer rated. Replacement with a correctly sized custom unit restores your protection and your NOA compliance.
- New additions or renovations with non-standard rough openings. When a contractor frames a bump-out or converts a wall into a window wall in South Beach or Mid-Beach, the rough opening rarely matches any catalog size. We field-measure and order to the exact dimension.
- Whole-home replacement where architectural character matters. Some homeowners on the Venetian Islands don’t want every window to look like it came off a production line. Custom impact windows let you match historical proportions and sightlines while still meeting 2026 Florida Building Code requirements.
Our Custom Impact Windows Process
We’ve refined this process over 15 years of working in Miami Beach’s mix of historic districts, high-rises, and waterfront estates. Here’s how a project actually runs from first call to final inspection:
- Same-day phone consultation and site scheduling. When you call (863) 656-0462, you reach a real person – not a voicemail, not a dispatch queue. We talk through what you have, what you need, and book a field-measure visit. No trip charge inside Miami-Dade County.
- Precision field measurement and opening assessment. A background-checked, uniformed Winslow technician comes to your home and takes detailed measurements of every opening, checks the existing frame condition, notes any water intrusion or rot at the sill, and photographs the rough opening for our fabrication order. If anything looks wrong with the framing, we tell you before we order glass – not after it arrives.
- Product selection and upfront pricing. Based on your openings, budget, and aesthetic goals, we walk you through options from brands like CGI and ES Windows – both of which carry Miami-Dade NOA approval across their impact product lines. You get a written quote with line-item pricing before a single dollar changes hands. Upfront pricing means no surprises on the invoice.
- Permit pulling and NOA documentation. Miami-Dade requires a permit for impact window replacement, and we handle the entire submission. We provide the product’s NOA number, the installation drawings, and the energy calculations. You don’t chase paper. This step alone is where many homeowners have been burned by contractors who install first and “handle permits later” – we never do that.
- Factory-direct fabrication and delivery coordination. Custom units are built to your field measurements at the manufacturer. Lead times vary by product line, but we give you a realistic window (CGI’s Miami facility typically runs faster than out-of-state fabricators) and we notify you the moment product ships.
- Professional installation and final inspection. Our uniformed crew installs to the manufacturer’s approved installation instructions – which is a requirement for the NOA to hold. After installation, we schedule the Miami-Dade building inspection and walk you through what the inspector will check. Once the inspection passes, you get your certificate of completion and a copy for your insurer.
Custom Impact Windows Pricing in Miami Beach
Custom impact windows in Miami Beach typically cost more than stock sizes, and that’s honest – the fabrication is more involved and the permitting requirements here are among the most detailed in the country. What you’re paying for is a window that will actually protect your home and satisfy your insurer.
| Window Type / Scenario | Typical Installed Price Range (Per Unit) |
|---|---|
| Custom single-hung impact window (non-standard size) | $850 – $1,400 |
| Custom impact casement or awning window | $1,100 – $1,800 |
| Arched or radius-top custom impact window | $1,500 – $2,800 |
| Large picture or fixed custom impact window (60″+ wide) | $1,800 – $3,500 |
| Full-home custom impact window package (avg. Miami Beach home) | $18,000 – $45,000+ |
Several factors move a project toward the higher end of these ranges in Miami Beach specifically:
- Miami-Dade High-Velocity Hurricane Zone (HVHZ) requirements. HVHZ is a stricter standard than the rest of Florida. Not every impact window on the market carries HVHZ approval – only units with a valid Miami-Dade NOA qualify, and those tend to command a price premium over products sold elsewhere in the state.
- Frame and sill condition. Older concrete block homes in Mid-Beach often have deteriorated stucco mold around the opening. If the substrate needs repair before installation, that’s additional labor. We flag this at the field-measure step so you know the full scope before we start.
- Glass package choice. Standard laminated impact glass, high-impact low-E for energy savings, or impact-rated tinted glass for oceanfront UV control – each has a different price point. For homes directly on the water in South Beach or Surfside, a low-E coating pays back in reduced AC load within a few seasons.
- Story height and access. Second and third-floor installations on multi-story homes along Indian Creek or the Venetian Causeway corridor require lift equipment or staging, which adds to labor cost.
Estimates are always free. Seniors and veterans receive a permanent 10% discount on every project, and if your total repair or installation exceeds $200, you get $40 off. Call (863) 656-0462 for an exact number on your specific openings.
FAQs – Custom Impact Windows in Miami Beach
Do custom impact windows qualify for Florida homeowner insurance discounts in Miami Beach?
Yes – Miami-Dade NOA-approved impact windows are one of the most impactful wind mitigation credits available under Florida’s wind mitigation inspection form. When your inspector documents that all openings have HVHZ-rated impact glazing, most insurers apply an opening protection credit that can reduce your wind premium by 20% to 45% depending on your carrier and policy structure. We provide the NOA documentation and the Miami-Dade certificate of completion that your insurer and inspector need. Call (863) 656-0462 and we’ll walk you through what paperwork comes with every completed job.
How long does it take to get custom impact windows made and installed in Miami Beach?
From signed contract to passed inspection, most custom impact window projects in Miami Beach run 6 to 12 weeks. The permit submission to Miami-Dade Building Department typically takes 2 to 4 weeks for approval, and custom fabrication adds another 3 to 6 weeks depending on the manufacturer and the complexity of the shapes involved. CGI, whose production facility is in Miami, often runs on the shorter end. We give you a realistic schedule at the time of your estimate – not an optimistic one we can’t keep. Call (863) 656-0462 to talk through timing for your specific project.
Can you match the look of my existing windows when replacing only some openings?
In most cases, yes. When we field-measure, we document the existing window’s sight-line dimensions, frame depth, exterior profile, and glass tint so we can specify a replacement that reads consistently from the street. CGI and ES Windows both offer multiple exterior finishes and glass options. Where an exact visual match isn’t possible – typically on very old or discontinued profiles – we’ll show you the closest available option and let you decide before anything is ordered. Partial replacement is common on Venetian Islands homes where only the front elevation is being updated for a wind mitigation inspection.
What is the 36500-Day Done Right Promise and does it apply to custom impact windows?
The 36500-Day Done Right Promise is Winslow’s commitment that if a job isn’t done right, we come back and make it right – full stop. It applies to every project we do, including custom impact windows. The name reflects a century’s worth of accountability: 36,500 days. No national chain makes that kind of commitment because no national chain has an owner whose name is actually on the business. Ed Winslow’s name is on ours, and that means every installation we do in Miami Beach is one we stand behind for the long term.
Why Miami Beach Homeowners Choose Winslow
Miami Beach’s building environment is genuinely different from the rest of Florida. The combination of HVHZ code requirements, Miami-Dade’s permit process, coastal corrosion exposure, and older architectural stock creates a set of conditions that out-of-town installers routinely underestimate. We’ve been working in this market since 2011, and Ed Winslow has personally overseen projects across South Beach, Mid-Beach, North Beach, Surfside, and the Venetian Islands. We know which inspectors are assigned to which zones, which products pass Miami-Dade review without hiccups, and where older homes tend to hide surprises behind their stucco.
Every technician who comes to your home is background-checked and arrives in a Winslow uniform. You know who to expect before the truck pulls up. Our pricing is written down before work begins, and we don’t add line items after the fact. If you’ve gotten a written estimate from someone else and want a second opinion, that second opinion is free – no obligation, no pressure to switch.
We’re authorized installers for CGI, ES Windows, CWS, and ECO Window Systems, among others – brands that carry genuine Miami-Dade NOA approvals across their impact lines. We don’t install products we can’t stand behind, and we don’t recommend upgrades you don’t need.
