Fast, Reliable Impact Windows Across Miami
Window Replacement - Miami typically runs $800 to $1,500 per window for standard openings, with whole-home packages landing between $8,000 and $25,000 depending on opening count and wind zone.

We work in Miami every week, from Coral Way to Normandy Isle, and we know what salt air off Biscayne Bay does to hardware, seals, and frames. That local knowledge changes the products we specify and the way we install them. When a neighbor on Shore Drive calls, we know the corrosion profile before we even pull up.
Why Winslow Windows & Doors Is Miami’s Preferred Impact Windows Company
Winslow Windows & Doors has been locally owned and operated by Ed Winslow since 2011. Our Impact Windows crews know Miami-Dade code inside out, because we build to it every single week. Ed’s name is on the door, and on every job. Not a franchise, not a call center, and not a rotating cast of subcontractors. Background-checked technicians in uniform show up when we say they will, and a live person answers our phone 24 hours a day, seven days a week.
Miami homeowners deal with a permitting and inspection system that is unlike anywhere else in the country. We are not guessing at the code. We verify Miami-Dade Notice of Acceptance (NOA) numbers before we order product, confirm design pressures match the opening, and handle the permit paperwork so the job passes the first time. Homeowners in Hialeah, Little Havana, and along North Bayshore Drive have trusted us with their Door Installation in Miami and windows for over a decade. Many found us by word of mouth from a neighbor, which is the review we value most.
You will get a published address, a real license number, and upfront pricing with no trip charge for estimates inside Miami-Dade County. We also offer a free second opinion on any written estimate you already have, plus a permanent 10% discount for seniors and veterans. If it is not done right, we make it right. That is our 36500-Day Done Right Promise, and it applies to every window we install in Miami.
Our Impact Windows Services in Miami
Impact Window Installation
We install Miami-Dade NOA certified impact windows in concrete block and wood-frame homes across Miami, including CBS construction from the 1950s through today. Every unit gets masonry anchors and flashing details sized for the rough opening, not a generic wood-frame kit. We handle the permit, the inspection, and the paperwork with the Miami-Dade Building Department.

Impact Window Replacement
If your Miami home still has original jalousie windows, you are living with zero hurricane resistance and an insurance carrier that may be losing patience. Replacing jalousies with impact-rated casements or single-hung units changes the security and the utility bill. We have done these replacements throughout North Miami and Allapattah, and we know the rough-opening framing challenges that come with 60-year-old block walls.

Sliding Glass and Patio Doors
Sliders in Miami take a beating from humidity and salt, especially within a mile of open water. We install Sliding Glass & Patio Doors in Miami with marine-grade rollers and stainless hardware. Whether you are replacing a corroded slider in a Biscayne Bay condo or upgrading a patio door in a Coral Gables Mediterranean, we size the door to the wind zone and verify the NOA before ordering.

Custom and Geometric Impact Windows
Not every Miami window is a standard rectangle. Arched openings over entry doors, trapezoid windows on mid-century ranches, and the divided-lite profiles Coral Gables requires all fall under our custom window work. We can match the window to the opening and to the historic overlay requirements, so you do not get a generic square jammed into a Mediterranean opening.

Trusted Brands We Service in Miami
We are an authorized installer for eight premium brands, including Eco Window Systems repair in Miami, and the three we spec most often are PGT, Mr-Glass, and Therma-Tru. PGT’s impact-rated casements and single-hungs carry the NOA numbers that pass Miami-Dade inspection, and their laminated glass interlayers hold up to the hurricane wind zone we live in. Mr-Glass gives us a strong custom-geometry option when a job calls for something beyond standard sizing, and Therma-Tru covers impact-rated entry doors that match our window packages. We stock common parts and hardware for these brands locally in the South FL Miami metro office, which shortens turnaround on service calls and warranty work for Miami customers.
Common Impact Windows Problems We See in Miami Homes
- Corroded aluminum frames and seized hardware. Within a mile of Biscayne Bay or the Atlantic, salt-laden air eats standard aluminum at the jamb and sash corners in under five years. We have pulled units where the locking hardware would not turn, and the sashes would not seal, because the original install used non-marine anodizing.
- Failed silicone seals around the insulated glass. Miami’s year-round humidity plus extreme UV degrades silicone faster than inland Florida markets. Water intrusion at the rough opening on a jalousie-to-impact retrofit is almost always a flashing problem from the original build, not the new window itself.
- Windows that pass state approval but fail HVHZ inspection. A window can carry Florida Product Approval and still lack the Miami-Dade NOA number needed to pass inspection in this county. Contractors who do not check this leave homeowners without wind mitigation credits and potentially uninsurable. We verify the NOA before we order.
- Wrong design pressure for the wind zone or floor height. Upper-floor openings and corners of buildings carry higher design pressure requirements. A unit rated for a ground-floor inland opening may not pass on a 4th-floor balcony facing the bay. We match design pressure to the specific opening, every time.
Pricing for Impact Windows in Miami, FL
Here is what we tell Miami homeowners on the first call, and it is what we put in writing. Standard impact windows in Miami run $800 to $1,500 installed per opening for typical sizes. Impact single-hung units land between $900 and $1,800. Large or custom openings, like a wide picture window or an arched transom, run $2,500 to $5,000. Whole-home packages across a typical Miami CBS ranch with 10 to 18 openings generally fall between $8,000 and $25,000.
What moves the number in Miami specifically: opening count, the wind zone of your address (coastal zones require higher design pressures), floor height for upper openings, frame material (aluminum vs vinyl), and whether Coral Gables historic overlay rules come into play. Estimates with a full in-home measure are free, and we put the number in writing before any work starts. Call (863) 251-5864 to schedule yours.
What Impact Windows Costs in Miami
Let us be plain about the price ranges, because a vague answer helps no one. Standard impact window installation in Miami runs $800 to $1,500 per window installed. Impact single-hung units tend to sit between $900 and $1,800 depending on size and wind-zone rating. Large or custom openings, like a wide fixed picture window or a geometric arch over a front door, run $2,500 to $5,000 each. Whole-home packages with 10 to 18 openings generally land between $8,000 and $25,000, with the higher end reflecting coastal wind zones, upper-floor design pressures, or Coral Gables historic-overlay complications.
In Miami, the specific wind zone of the address moves the number more than any other factor. A house a mile inland in Westchester may qualify for a lower design pressure than a condominium facing Biscayne Bay. Upper floors need higher-rated units. Aluminum frames cost more than vinyl but survive better in salt air when specified with marine-grade finishes. We do a free in-home measure, verify the NOA and design pressure for every opening, and give you a written line-item quote before any commitment.

FAQs - Impact Windows in Miami
A Miami-Dade Notice of Acceptance (NOA) is the county-specific product certification every impact window or door must carry to pass inspection in Miami. It sits on top of Florida Product Approval, and no other metro in the country requires this dual-layer standard. A window can pass state approval and still lack an NOA, which means a failed HVHZ inspection and a homeowner who is likely uninsurable. We verify the NOA number before we order product, and we show it to you on the written quote. Call (863) 251-5864 for a free estimate and we will check the NOA on every opening.
Yes. Salt-laden air off the bay corrodes standard aluminum frames and hardware in under five years within roughly a mile of open water. We have removed window units in North Miami where the locking mechanisms were seized solid from salt, and the sashes would not close enough to seal. Marine-grade anodizing or powder coating, along with stainless hardware, is the difference between a window that functions for decades and one that does not. The upfront cost is small compared to replacing hardware and weatherstripping repeatedly. A free estimate will tell you whether your address falls in the coastal corrosion zone.
Yes. On a 1962 CBS ranch in North Miami, we replaced original jalousie windows with PGT impact-rated casements after the homeowner’s insurer threatened non-renewal. The salt air off Biscayne Bay had corroded the old aluminum frames so badly the sashes would not seal, and the new laminated glass interlayer met the HVHZ large-missile rating while keeping the mid-century profile intact. The NOA number was verified on-site before we ordered any product. If you have jalousies in Hialeah, Little Havana, or North Miami, call (863) 251-5864 and we will evaluate your openings.
Impact windows certified for wind-mitigation frequently reduce the windstorm portion of a Miami homeowner’s premium, often by around 25% after a wind-mitigation inspection. The inspection itself typically runs $75 to $150. My Safe Florida Home matching grants may cover up to $10,000 toward qualifying wind-mitigation upgrades, and Florida offers a sales-tax exemption on impact-resistant windows and doors. Final credits are set by your carrier and the inspection results, so we never guarantee a specific dollar figure. We will provide the documentation your inspector needs, including NOA numbers and design pressure ratings. Call (863) 251-5864 for details.
Coral Gables enforces its own historic-preservation overlay on top of HVHZ code. Impact windows on Mediterranean Revival homes must match original divided-lite profiles, and many projects require City Beautiful Board approval before a permit is issued. That approval path can add months and changes product selection entirely compared to an identical job one street over in unincorporated Miami-Dade. The window itself may be the same core product, but the frame profile, lite pattern, and permitting labor are different. Call (863) 251-5864 for a free estimate and we will tell you whether your Coral Gables address triggers the overlay.
Florida Pays You Back
The incentive stack for Miami homeowners doing impact windows is worth understanding, and the numbers are real even if the final figures come from your carrier and the programs themselves. My Safe Florida Home matching grants can cover up to $10,000 toward qualifying wind-mitigation upgrades, and Miami-Dade residents in older homes are exactly the audience the program exists for. Florida’s sales-tax exemption on impact-resistant windows and doors removes the tax line on the invoice for qualifying units. The federal 25C energy credit adds 30% of product cost, up to $600 per year, on qualifying energy-efficient units. Then there is the windstorm-premium credit, which commonly lands around 25% off the windstorm portion of your premium after a wind-mitigation inspection in the $75 to $150 range.
We do not control these programs, and we will not promise you a dollar figure your carrier has not confirmed. What we do is hand you the documentation: NOA numbers, design pressure ratings, installation date, and the wind-mitigation paperwork your inspector expects. For Miami homeowners replacing jalousies in a pre-Hurricane Andrew home, the combination of insurance pressure and incentives often makes the replacement a breakeven or better decision over a few years. Call (863) 251-5864 and we will walk through the specifics for your address.
Impact Windows vs Hurricane Shutters in Miami
Shutters protect glass from flying debris, but only someone at home, awake, and physically capable of hauling panels can deploy them. That is a real problem when a storm approaches while you are out of town, or when a family member with limited mobility is home alone. Impact windows are permanent protection, sealed and working 24 hours a day without anyone lifting a finger. In Miami-Dade, where hurricane season runs June through November and evacuations are a fact of life, the house either protects itself or it does not. Winslow does not sell or install shutters. We specialize in permanent impact-rated glazing, and for most Miami homeowners replacing windows anyway, the incremental cost over shutters pays back in reduced insurance premiums and a home that is ready for the storm whether or not you are in it.
What Actually Survives Within a Mile of Biscayne Bay
Miami-Dade County is the only metro in the U.S. where every impact window must carry a Miami-Dade Notice of Acceptance (NOA) in addition to Florida Product Approval - a dual-layer certification that standard big-box store windows typically cannot pass. A contractor who does not verify the NOA number before ordering product will fail inspection and leave a homeowner unable to get wind mitigation credits, potentially uninsurable after hurricane season. That is a hard fact of this local market, and it is the first thing we check on every quote.
Within a mile of Biscayne Bay or the Atlantic, the salt air decides the materials, not the schedule. Standard aluminum frames corrode at the jamb and sash corners in under five years if marine-grade anodizing or powder coating is not specified. We have pulled units where the hardware is seized solid from salt, the silicone around the insulated glass unit has degraded from year-round humidity, and the rough-opening flashing from the original build was never designed for impact-rated glazing. The coastal-spec upgrade, stainless fasteners, marine-grade frames, and properly sealed joints, costs more on the front end. The inland-spec version costs more within a decade, because you will replace the hardware, weatherstripping, or the entire window long before the coastal-spec unit gives out.
This page is the only Miami impact window resource that tells you which specs actually survive within a mile of Biscayne Bay, and which big-box units will get your NOA denied before the first hurricane. If you want a free second opinion on a written estimate, or a fresh quote with the NOA verified before we order, call (863) 251-5864. Ed’s name is on the door, and on every job we do in Miami.
