Impact Windows in Miami — Installed Right, Permitted, Inspected
NOA-certified impact windows for South Florida's wind code. Permits pulled on every job. No unlicensed crews, no substituted products, no surprises on inspection day.
Why This Matters Here
South Florida Has the Strictest Window Code in the Country
Miami-Dade and Broward sit in the High Velocity Hurricane Zone (HVHZ) — the only counties in the United States that require products to meet Miami-Dade's Notice of Acceptance before installation. The NOA is not a suggestion or a marketing claim. It's a county-issued certification that the window has been tested under conditions that simulate a Category 5 hurricane.
Standard windows — even “hurricane-rated” ones sold at big-box stores — do not carry Miami-Dade NOAs. If a contractor installs them in Miami-Dade or Broward, the installation fails inspection. If a storm damages your home and those windows weren't NOA-certified, your insurance company has grounds to deny the claim.
Every window we install carries a valid NOA. We verify it before the job starts and provide the NOA number in your documentation package. (If a contractor can't produce an NOA number, that's a problem worth addressing before you sign anything.)
What They Actually Do
Not Just Wind Protection — Though That Too
Impact windows are built with laminated glass — two panes bonded with a polymer interlayer. When struck, the glass breaks but stays in the frame. Wind and rain don't enter. Pressure equalization inside the home is maintained. That's what protects the structure during a hurricane.
The laminated glass also blocks about 99% of UV radiation — which matters for floors, furniture, and artwork in a climate where direct sun lasts 8–10 hours a day. Most impact glass also carries a Low-E coating that reflects heat, which reduces the load on your AC system. Year-round, not just during hurricane season.
There's also the noise question. South Florida homes near highways, airports, or commercial corridors see a meaningful reduction in ambient noise after impact installation. That's not a marketing point — it's physics. Two panes with a polymer interlayer absorbs sound in a way a single-pane window never could.
Wind & Pressure Resistance
Tested to withstand 140–200+ mph wind loads depending on product rating. Frame and glass stay intact.
No Storm Prep Required
Permanently installed protection. Nothing to deploy, store, or worry about when a storm tracks faster than expected.
UV Blocking
Laminated glass blocks ~99% of UV radiation. Prevents fading of floors, furniture, and art.
Energy Efficiency
Low-E coatings reduce solar heat gain. Lower AC load year-round.
Sound Reduction
Significantly quieter interior. Noticeable near busy roads, airports, or commercial areas.
Insurance Discounts
Wind mitigation credits apply once all openings are protected. Provide documentation to your insurer for a re-rate.
Window Styles
Impact Windows Come in Every Common Style
We install the style that fits your opening — not the one we happen to stock. Here's what's typically available for South Florida homes.
Single-Hung Impact
Best for: Most bedrooms and utility windows
Lower sash opens; upper sash fixed. Most common replacement style.
Double-Hung Impact
Best for: Rooms needing top and bottom ventilation
Both sashes operate. Easier to clean from inside.
Casement Impact
Best for: Ocean-facing and high-exposure walls
Single pane swings outward. Excellent seal, maximum view.
Sliding / Horizontal Roller
Best for: Wide openings, living areas
Glides on a track. Works well where swing clearance is limited.
Picture / Fixed
Best for: Large feature windows, stairways
No moving parts. Maximum light. Used where ventilation isn't needed.
Impact Sliding Glass Doors
Best for: Patios, pool areas, back of home
Replaces standard sliders. Full laminated glass panel.
Florida Building Code
The 25% Rule — and Why It Changes Your Calculus
Florida code requires that if window replacements in a 12-month period exceed 25% of your total window area, all remaining windows must be upgraded to current code. In Miami-Dade and Broward, current code means impact-rated.
Many homeowners start by replacing a few windows, hit the 25% threshold without realizing it, and then face a code-mandated whole-home replacement under pressure. We check your full window count before quoting so you know what you're actually committing to — and can plan the project accordingly.
How It Works
From First Call to Final Inspection
Six steps. We handle the permit, the county inspector, and the documentation your insurer needs.
Free In-Home Estimate
We measure every opening, check the existing frame condition, and walk you through product options — impact-rated glass, frame material, and Low-E coatings. You get a written quote before any decision.
Product Selection & NOA Verification
All products we install carry a valid Miami-Dade Notice of Acceptance. We confirm the NOA number for your records and your insurer. No substitutions mid-job.
Permit Application
We pull the permit. Miami-Dade typically takes 3–6 weeks. Broward and Palm Beach: 1–3 weeks. No permit means no county inspection, no protection, and problems at resale.
Installation
Existing windows removed, new impact units set and sealed. Most single-family homes complete in 1–3 days depending on window count and complexity.
County Inspection
County inspector reviews the installation against the permitted drawings. We schedule and coordinate. You don't need to do anything.
Insurance Documentation
After inspection sign-off, we provide the permit and NOA documentation your insurer needs to apply wind mitigation discounts. Call your agent and request a re-rate.

When We're Not the Right Fit
If you're replacing a single broken window as an emergency and price is the only factor, we're probably not your call. We don't do partial-permit workarounds and we don't substitute products to make a lower number work on paper.
If you're doing a whole-home replacement, replacing windows as part of an addition or renovation, trying to qualify for insurer wind discounts, or just want the job inspected and documented correctly — that's where we do our best work.
We serve Miami-Dade, Broward, and Palm Beach County. Most estimates go out within 48 hours of the site visit.
Common Questions
Frequently Asked Questions
How much do impact windows cost in Miami?
Installation cost depends on the number of openings, window style, frame material, and whether existing frames need replacement or can be reused. We provide a free written estimate after measuring your home — the number we give you is the number you pay. Call (786) 983-7928 to schedule.
What is the 25% rule for windows in Florida?
Florida building code states that if window replacements exceed 25% of the total window area within a 12-month period, all remaining windows in the home must be upgraded to current code — which in Miami-Dade and Broward means impact-rated product. Many homeowners discover this mid-project. We look at your full window count before quoting so you know whether a partial replacement triggers a whole-home requirement.
Do impact windows reduce homeowner's insurance in Florida?
Yes — in most cases meaningfully. Florida insurers apply wind mitigation credits for impact-rated openings, particularly in Miami-Dade and Broward. The exact discount depends on your insurer, your current coverage, and how many openings are protected. After installation and county inspection, take the permit documentation and NOA numbers to your insurer and request a wind mitigation re-rate.
Can I get a tax credit for impact windows in Florida?
Potentially yes. The federal Inflation Reduction Act includes an Energy Efficient Home Improvement Credit (25C) for qualifying ENERGY STAR-certified windows — currently 30% of the product cost, up to $600 per year. Impact windows with Low-E coatings often qualify. Confirm with your tax professional before filing. This is a federal program — we can't guarantee your specific windows qualify, but many do.
Do I need a permit to replace windows in Miami-Dade?
Yes, always. Miami-Dade requires a permit for any window replacement, and all products must carry a valid Miami-Dade NOA (Notice of Acceptance). A contractor who offers to skip the permit is operating illegally and exposing you to code violations, insurance complications, and liability at resale. We pull permits on every job.
What is a Miami-Dade NOA and why does it matter for windows?
NOA stands for Notice of Acceptance — Miami-Dade County's certification that a window product has been tested to withstand High Velocity Hurricane Zone wind loads. Any impact window installed in Miami-Dade or Broward must carry a valid NOA. Without it, the installation doesn't meet code, and your insurer can deny a storm-damage claim on those openings.
How long does impact window installation take?
Most single-family homes with 10–20 openings complete in 1–3 days. Larger homes or projects with custom sizes take longer. The permit process is the longer part — Miami-Dade typically runs 3–6 weeks from application to approval. We factor that into the timeline we give you upfront.
Should I get impact windows or accordion shutters?
Impact windows are permanently installed and require nothing from you during a storm — no installation, no storage, no panels to misplace. Shutters require someone to deploy them before every storm, which matters when you're out of town or a storm tracks faster than expected. Impact windows also provide year-round benefits: noise reduction, UV filtering, and energy efficiency. The right choice depends on your home layout, HOA requirements, and how you plan to use the property.
Get a Free Impact Window Estimate
We measure every opening, confirm the NOA for your specific product, and give you an all-in written number. No vague ranges, no post-installation surprises.
If shutters are a better fit for your home than impact windows, we'll tell you that too. The goal is a protected home — not a larger invoice.
