AfterFast, Reliable Impact Windows Across Miami
Window Replacement - Miami typically runs $800 to $1,500 per window installed, with whole-home projects landing between $8,000 and $25,000 depending on opening count, frame material, and wind zone. Most Miami replacements are driven by Miami-Dade County’s Notice of Acceptance (NOA) requirement, which is stricter than the statewide Florida Product Approval used in Broward and Palm Beach. If you’re pricing impact windows in Miami, call (863) 946-5039 and we’ll give you a written line-item quote with no trip charge inside our home county.
Winslow Windows & Doors has installed impact-rated windows and doors across Miami for years, from Coral Gables bungalows to Brickell high-rises. Ed Winslow’s name is on the door, and on every job we do. We stock PGT, CGI, and CWS units in configurations that carry Miami-Dade NOAs, and our crews know exactly what Miami’s inspectors look for before the permit closes. For the full picture on what we install, see our Impact Windows team’s process.
Why Winslow Windows & Doors Is Miami’s Preferred Impact Windows Company
Miami homeowners call us because we answer the phone. Every call, day or night, is picked up by a live person at (863) 946-5039, not a voicemail loop. That matters when a storm is two days out and you need to know whether your openings will pass a wind mitigation inspection.
We’re locally owned and owner-operated, founded in 2011 by Ed Winslow, with a published address and license number. Every technician who shows up at a Miami home is background-checked and in uniform, so you know who’s at your door before the truck parks. We serve Miami neighborhoods directly, with dispatch and scheduling coordinated from our Miami (South FL) office.
The reviews from Miami homeowners consistently point to the same things: written quotes that match the final invoice, crews that show up on schedule, and permits that close without reinspection drama. That last part matters more here than anywhere else in Florida, and we’ll explain why below.
Our Impact Windows Services in Miami
PGT Impact Windows With Miami-Dade NOA
PGT is the most common request we field in Miami, and for good reason. Their WinGuard and 5500 series lines carry Miami-Dade NOAs with large-missile ratings, which is the baseline Miami-Dade County actually enforces. A Florida Product Approval alone is not enough here. We order every unit by the specific NOA number that matches the opening size, frame type, and wind zone for your address, and that NOA number stays in the permit file.
Concrete Block (CBS) Rough Opening Reconstruction
Miami’s housing stock is dominated by concrete block construction from the 1950s through the 1980s, especially in Hialeah, Little Havana, and Liberty City. Many of those homes still carry original jalousie or single-pane aluminum windows. Modern impact units weigh significantly more than those old louvered frames, so the rough opening has to be rebuilt with reinforced bucking anchored into the masonry. A cheap quote skips this step and the inspector catches it. We build it right from the substrate out.
Large-Missile Impact-Rated Doors
Entry doors and Sliding Glass & Patio Doors in Miami must meet the same impact standard as windows. For sliding glass and French door replacements, we install large-missile rated systems from CGI and Therma-Tru, each carrying the Miami-Dade NOA specific to the configuration. This is not a place to save money with a statewide-approval-only door that fails NOA review at reinspection.
High-Rise and Condo Impact Windows
Brickell and Edgewater condos present a different set of challenges: condo association approvals, high-floor wind pressure zones, and design pressures that climb with elevation. We match the design pressure rating to the actual opening height and exposure, never exceeding +/-100 PSF on any unit we spec. Large-format impact glazing for floor-to-ceiling openings is something we order regularly for high-rise work, and we coordinate with condo boards on the documentation they require.

Trusted Brands We Service in Miami
Winslow Windows & Doors is an authorized installer for PGT, CGI, Cws service in Miami, ES Windows, ECO Window Systems, Therma-Tru, and ViewLux. For Miami work, we lean heavily on PGT, CGI, and ES Windows because those lines carry the most comprehensive Miami-Dade NOA coverage across standard and custom sizes. That means we’re not re-ordering units mid-project or asking a homeowner to accept a different product than what was quoted. Miami-specific configurations are what we order every week, so lead times are predictable and the permit package stays clean.
What Impact Windows Costs in Miami
Here’s a straight pricing picture for Miami’s market, based on the openings we actually quote:
| Scope | Typical Cost Range (Installed) |
|---|---|
| Impact window (standard opening) | $800-$1,500 per window |
| Impact single-hung | $900-$1,800 per window |
| Large or custom openings | $2,500-$5,000 per unit |
| Whole-home package (10+ openings) | $8,000-$25,000+ |
What moves the price in Miami: the number of openings, the wind zone your address sits in, the floor height (high-rise units cost more to engineer and install), and the frame material. Aluminum is common and corrosion-resistant, but vinyl offers better insulation at a slightly higher product cost. On older CBS homes, expect rough-opening reconstruction to add real labor costs. A compliant quote includes it; a cheap quote hides it.

Every Miami Impact Window Needs a Miami-Dade NOA. Not Just a Florida Product Approval.
Here’s the thing most Miami homeowners don’t find out until inspection: a Florida Product Approval is not enough in Miami-Dade County. Every replacement impact window and door must carry a Miami-Dade Notice of Acceptance, a certification stricter than what neighboring Broward or Palm Beach counties enforce. This is not a technicality. If your contractor installs a statewide-approval-only unit, the Miami-Dade building inspector can fail the permit at final inspection, and then you’re paying for a tear-out and reinstallation.
This makes local permit and inspection compliance a different job in Miami than anywhere else in the metro. The NOA is tied to the specific product, size, frame, and wind zone. We pull the NOA for every opening before ordering, file it with the permit package, and make sure the paper trail survives reinspection. Our Impact Windows team handles this daily. Big-box retail installs often don’t, and we get called in to fix those.
Because Florida’s property insurance crisis has carriers refusing renewals or tripling premiums on homes without verified impact-rated openings, Door Installation in Miami and window replacement are simultaneously a life-safety upgrade, a building code mandate, and the single fastest way to lower an insurance bill. That combination exists almost nowhere else in the country. Get the NOA right and the insurance credit follows. Skip it and you’ve paid for an upgrade your insurer will not recognize.
Common Impact Windows Problems We See in Miami Homes
- The Florida Product Approval-only unit that fails Miami-Dade NOA review. This is the most expensive mistake we fix. A contractor installs windows that meet statewide code but not Miami-Dade’s stricter standard. The inspection fails, the permit stalls, and the homeowner pays for a tear-out. Always confirm the NOA number before the order is placed.
- Salt air corrosion from Biscayne Bay. Homes within a mile of the water see non-marine aluminum frames oxidize and seals fail within 8 to 10 years. Miami’s year-round humidity above 70% accelerates the damage. We spec marine-grade frames on coastal work for exactly this reason.
- Jalousie windows that no impact retrofit can save. West Little Havana, Hialeah, and older sections of Miami still have thousands of 1960s and 1970s jalousie windows. They have zero impact resistance and a U-factor that makes them nearly useless for insurance purposes. You can’t just swap the glass; the entire rough opening needs reconstruction with reinforced bucking into the masonry.
- The skipped wind mitigation inspection. Installing impact windows doesn’t automatically lower your premium. Florida Statute 627.0629 requires a wind mitigation inspection to document the upgrade before insurers apply the credit. Homeowners who skip this step leave real money on the table every year.
Florida Pays You Back
Miami homeowners have a stack of incentives available right now, and we help you navigate each one:
- My Safe Florida Home matching grants: up to $10,000 for qualifying wind mitigation upgrades, including impact windows and doors. These grants are competitive and fund-limited, so application timing matters.
- Florida sales tax exemption: impact-resistant windows and doors are exempt from state sales tax. That’s an instant 6% savings in Miami-Dade.
- Federal 25C energy credit: 30% of product cost, up to $600 per year, on qualifying energy-efficient window units. Impact windows with low-E glass typically qualify.
- Windstorm premium credits: after a wind mitigation inspection ($75 to $150), most Miami homeowners see an average reduction around 25% on the windstorm portion of their premium. Exact numbers are set by the carrier, not us.
None of these are guarantees, and the programs change. What we do is make sure the documentation is in order: NOA numbers, permit closure, and the wind mitigation inspection report. That’s the sequence that actually moves your insurance bill.
Impact Windows vs Hurricane Shutters
Shutters are cheaper upfront, but they only work if someone is there to panel them up. Impact windows are always on, always protecting. For Miami homeowners who travel for work or keep a second home, shutters leave windows vulnerable the moment a storm track shifts and nobody’s around. Impact windows also hold value differently: permanent protection is documented on the wind mitigation report, and insurance credits apply year-round, not just when shutters are deployed. We don’t sell or install shutters. We install windows that do the job without you lifting a panel.
What a Compliant Miami Impact-Window Quote Includes (And What a Cheap One Leaves Out)
Every Miami permit application for impact windows should include the NOA number for each opening, matched to the unit’s size and wind zone. A compliant quote includes that documentation. It also includes rough-opening reconstruction on older CBS homes, large-missile rated glass for openings below 30 feet, and marine-grade frame finishes within a mile of the coast.
What a cheap quote leaves out: the NOA paperwork, the reinforced bucking, the large-missile glazing upgrade, and the wind mitigation inspection coordination. The price looks lower on day one and far higher when the inspector red-tags the job or the insurer won’t apply the credit. On a concrete block home in West Little Havana, our crew pulled out 1970s jalousie windows and had to rebuild the rough openings with reinforced bucking into the masonry before we could set the new PGT impact units, each one carrying a Miami-Dade NOA and large-missile rating. The homeowner’s insurer would not even discuss renewal until the permit closed with the wind mitigation inspection on file. That’s the difference between a quote and a finished job.

FAQs - Impact Windows in Miami
Every replacement impact window and door in Miami-Dade County needs a Miami-Dade Notice of Acceptance. A Florida Product Approval is not accepted by Miami-Dade building inspectors for replacement units. The NOA certifies that the specific product, size, and configuration meets Miami-Dade’s stricter wind and impact requirements. If a contractor tells you a statewide approval is sufficient, get that in writing and compare it against what the inspector will actually enforce. Call (863) 946-5039 and we’ll show you the NOA paperwork before any order is placed.
After installation and permit closure, you schedule a wind mitigation inspection with a licensed inspector, typically $75 to $150. The inspector documents the impact-rated openings, the roof-to-wall connections, and other wind-resistant features, then files the report in the Florida Wind Mitigation Database. Your insurer reads that report and applies the credit under Florida Statute 627.0629. Homeowners who skip the inspection get no premium reduction. We coordinate the inspection timing with every Hialeah installation so the permit closes and the report files in the right sequence.
No. Jalousie windows, common in older Miami homes through the 1970s, cannot be retrofitted with impact glass. The aluminum louver frames were never engineered for the weight or wind load of an impact-rated unit, and no NOA exists for that conversion. Meeting code means full replacement with rough-opening reconstruction: reinforced bucking anchored into the masonry so the new unit carries the design pressure rating the permit requires. It’s more labor, but it’s the only path that passes inspection and earns the insurance credit.
High-rise units on Brickell need design pressure ratings matched to the opening’s height, exposure, and wind zone, typically higher than a single-story home at the same address. The rating is expressed in pounds per square foot (PSF), never above +/-100. We calculate the required design pressure for each opening based on Miami-Dade’s wind zone maps and the specific elevation. The NOA for a high-rise unit must match that design pressure and the large-missile impact requirement. Your condo association may also require additional engineering sign-off. Call (863) 946-5039 and we’ll spec it correctly the first time.
A compliant quote includes the Miami-Dade NOA number for every opening, rough-opening reconstruction on older CBS homes, large-missile rated glazing, marine-grade finishes for coastal exposure, permit fees, and coordination of the wind mitigation inspection. A cheap quote leaves out the NOA paperwork, the reinforced bucking, the large-missile upgrade, or the inspection step. You find out when the inspector fails the job or the insurer won’t apply the credit. That’s a $10,000 mistake dressed up as a $6,000 deal. Our quotes are line-item written and never change mid-project.
