AfterFast, Reliable Window Replacement Across Miami
Window replacement in Miami means something different than it does anywhere else in Florida. You’re not just swapping glass. You’re upgrading openings that have to survive Category 5 wind loads, salt air off Biscayne Bay, and a building inspector who will check every Miami-Dade Notice of Acceptance number on the unit. We’ve done this work in Westchester, Hialeah, Coral Gables, and the neighborhoods along US-1. Ed Winslow runs this company the way you’d expect from someone whose name is on every job: direct answers, real pricing, and windows that pass inspection the first time. Call (850) 930-1813 for a free in-home measure and written quote.
Why Winslow Windows & Doors Is Miami’s Preferred Window Replacement Company
We’ve been doing window replacement in Miami long enough to know what the cheap bids leave out. A jalousie-to-impact conversion on a 1960s CBS home in Westchester isn’t a pop-out-pop-in job. It’s custom buck framing, anchor spacing matched to concrete block, and product approvals verified against the specific size and model you’re buying. Homeowners here have been burned by out-of-town estimators who underbid the framing and then disappear when the inspector flags the rough opening. That doesn’t happen with us. Ed’s name is on the door, and our address and license number are published for anyone to check.
Our Miami customers call us because a live person answers the phone at any hour. No call centers, no voicemail loops. Ed Winslow’s cell rings. Our technicians are background-checked, uniformed, and show up knowing exactly what they’re looking at before the truck pulls up. When you call about windows near Miami Shores or a condo off Brickell, you get someone who understands what HVHZ compliance actually requires, not a dispatcher reading from a script.
Our Window Replacement Services in Miami
Every window we install in Miami has to meet the High Velocity Hurricane Zone standard. That’s non-negotiable. Here’s what we handle, and how each one applies to Miami homes specifically.
Full Frame Replacement
Full frame replacement means we remove everything down to the rough opening, including the old frame and trim, and install a completely new unit. In Miami’s CBS construction, this is often the only correct path when jalousie windows or corroded aluminum frames are coming out. The old rough openings were sized to a standard that no longer exists, which is why we custom-buck each opening to fit modern Miami-Dade NOA impact units. This is the repair done right, not the repair done cheap. Expect a full frame replacement in Miami to run $1,200-$2,400 per opening depending on size and floor height.
Insert Window Replacement
If your existing frames are square, solid, and not corroded by salt air, an insert replacement keeps the frame and replaces the sash and glass. It’s faster and costs less, typically $800-$1,500 per window in Miami. Insert replacements make sense on newer homes, post-Andrew construction, or condos where the HOA doesn’t allow full frame changes. But in older Coral Gables or West Little Havana homes where the aluminum has been eating Biscayne Bay salt for 40 years, we’ll tell you honestly if an insert would just be throwing money at a failing frame.
Vinyl Replacement Windows
Vinyl windows have a real advantage in Miami’s salt environment: they don’t corrode. Aluminum is strong, but the marine air shortens its life noticeably. Vinyl impact units from ECO Window Systems carry Miami-Dade NOAs and hold up far better within a few blocks of the water. They’re also the best value for whole-home replacements in Hialeah and Westchester, where most houses have 8 to 14 openings. A typical vinyl impact window in Miami runs $800-$1,400 installed.
Energy-Efficient Upgrade
Miami’s electric bills are driven by air conditioning, and single-pane jalousie windows are basically holes in the wall from an energy standpoint. Low-E insulated glass in an impact-rated frame cuts solar heat gain dramatically and qualifies for the federal 25C energy credit. We install Mr-Glass Energy-Efficient Windows - Miami regularly. A full home of energy-efficient impact glass in Miami typically runs $10,000-$22,000 depending on opening count, and the windstorm premium savings start the day your wind mitigation inspection is filed.

Trusted Brands We Service in Miami
Winslow Windows & Doors installs products from eight authorized brands, including PGT, Cgi in Miami, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru. We stock local parts for Miami customers and we’re an authorized installer, not a broker selling whatever’s on sale in a warehouse. That matters when a Miami-Dade inspector asks for the NOA on a specific size and configuration. We can pull that documentation before we ever order the unit. For Miami homes we most often recommend PGT and ECO Window Systems impact windows because their Miami-Dade approvals cover the widest range of sizes without custom engineering.
Common Window Replacement Problems We See in Miami Homes
- Original jalousie windows with zero hurricane resistance. These louvered-glass cranks are still in thousands of pre-1992 Miami homes. They fail every current code, leak conditioned air constantly, and offer no opening protection. Replacing them with impact units almost always requires custom buck framing because the rough openings don’t match any modern window size.
- Salt-air corrosion on aluminum frames within a few miles of Biscayne Bay. Coastal Miami neighborhoods like Coconut Grove and Edgewater see aluminum frames pitting and seals failing years faster than inland areas. If the frame is corroded, an insert replacement is the wrong fix. You need a full frame swap to vinyl or a marine-grade aluminum product.
- Non-compliant windows installed by contractors who never pulled a permit. We follow behind this constantly. Homeowners in Hialeah and Westchester bought “impact windows” from a big-box store, a handyman installed them without a Miami-Dade NOA check, and the inspector red-tagged the job. Now the homeowner pays twice. This is exactly why the cheap quote ends up being the expensive one.
- Failed insulated glass seals causing fogging and condensation. Miami’s humidity finds every weak seal. Once the argon or krypton gas escapes, the window fogs permanently. It has to be replaced, not repaired. In salt-heavy zones this happens faster on aluminum spacers, which is why we recommend warm-edge spacer systems on coastal installs.
Pricing for Window Replacement in Miami, FL
Honest numbers, no games. A standard impact window replacement in Miami runs $800-$1,500 per window installed. Impact single-hung units run $900-$1,800. Large custom openings or corner units run $2,500-$5,000. Whole-home packages typically land between $8,000 and $25,000, depending on opening count, floor height, and whether we’re doing full frame replacements throughout or a mix of inserts. What moves the price in Miami specifically: wind zone design pressures, first-floor versus upper-floor requirements, jalousie-to-impact conversions that need buck framing, and whether the existing frames are salvageable. Every quote is written, line-itemed, and fixed. No change orders on our own scope. Call (850) 930-1813 for a free in-home measure and written quote.
What Window Replacement Costs in Miami
Let’s get more specific. Impact windows in Miami generally run $800-$1,500 per window installed. Impact single-hung windows run $900-$1,800 per opening. Large or custom openings, the ones over 40 square feet or with unusual geometry, run $2,500-$5,000 each. Whole-home packages land between $8,000 and $25,000 or more, depending on how many openings you have and what condition the frames are in. In Miami, your price is driven by four things: opening count, wind zone and floor height, frame material, and whether the old unit is a jalousie that needs buck framing. A first-floor window in a flood-adjacent neighborhood carries a higher design pressure requirement than a third-floor window in the same building. That’s not markup. That’s physics. Call (850) 930-1813 for a free in-home measure and a written line-item quote.
Florida Pays You Back
The incentives stack, but only if the windows are actually compliant. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades including impact windows. Florida also exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit returns 30% of the product cost, up to $600 per year, on qualifying energy-efficient units. And after a wind mitigation inspection (which typically costs $75-$150), most Miami homeowners see a windstorm premium credit averaging around 25% on the windstorm portion of their policy. No guarantees, the programs and carriers set the final numbers, but these are real offsets that any compliant installation should unlock. We document every NOA and Florida Product Approval number on your quote so the credits and credits are there when you file.
One comparison worth making: impact windows versus hurricane shutters. Shutters only protect you if someone hangs them, and Miami’s afternoon thunderstorms don’t wait for you to get home from work. Impact windows are permanent protection. No panels to store, no tracks to maintain, no scramble when a storm forms in the Caribbean. You get opening protection 365 days a year, plus the energy and noise benefits shutters can’t touch. That’s why Miami homeowners replacing windows almost always choose impact units over shutters, and it’s why the insurance credit is higher for documented permanent protection.

FAQs - Window Replacement in Miami
A compliant window replacement in Miami must have a Miami-Dade Notice of Acceptance (NOA) for the exact model, size, and configuration installed, plus a Florida Product Approval number and design pressure rating matched to the opening’s wind zone and height. The permit package must also include anchor spacing and installation details that match the manufacturer’s approved drawings. If any of that is missing, the inspector rejects the job. Call (850) 930-1813 and we’ll pull the documentation before you buy a single unit.
Because the big-box store doesn’t verify the Miami-Dade NOA for the specific size and pressure rating your opening requires, and most handymen don’t know how to anchor into CBS block walls to manufacturer spec. The inspector will check both. When it fails, you pay for the windows twice, plus the labor twice. A licensed impact specialist is the only person who should touch this work in Miami.
A large-missile rating means the window can take a 9-pound 2×4 fired at it at 34 mph without penetration, twice. Design pressure is the structural rating for how much wind load the unit and its anchoring can withstand, positive and negative, measured in pounds per square foot. Miami requires both, and the design pressure requirement changes by floor height and exposure. A window that passes the missile test but is under-rated for pressure still fails inspection.
Replacing jalousie windows with Miami-Dade NOA impact units typically triggers a windstorm premium credit averaging around 25% on the windstorm portion of your policy, after a wind mitigation inspection documents the large-missile rating and Florida Product Approval numbers. In some cases it’s the difference between a carrier renewing your policy or dropping it. Call (850) 930-1813 for a quote that includes every documentation detail your insurer will want.
Yes, insulated low-E glass is standard in Miami-Dade NOA impact windows. The insulated glass unit sits inside the impact-rated laminated outer layer, so the window meets both the energy code and the hurricane code. You don’t sacrifice one for the other. We install Mr-Glass units with low-E insulated glass regularly across Miami.
