Fast, Reliable Window Replacement Across Miami
Window replacement in Miami is not a cosmetic decision. It is a structural one. Every opening in your home has to meet Miami-Dade County’s High Velocity Hurricane Zone standards, which means the product carries a Notice of Acceptance (NOA) number specific to this county. No other Florida approval is enough. Our team at Winslow Windows & Doors knows exactly which units pass inspection the first time because we work inside these code requirements every week. If your windows are original to a house built anywhere from the 1950s through the 1980s, they are almost certainly single-pane aluminum or jalousie, and neither holds up to current wind-load or insurance standards. Call (727) 483-7883 for a free in-home measure and a written quote that is fixed before we order anything. Ed Winslow’s name is on the door, and on every job we do in Miami, Coral Gables, Hialeah, and the rest of Miami-Dade.

Why Winslow Windows & Doors Is Miami’s Preferred Window Replacement Company
We have been installing impact windows and doors since 2011, and Miami is one of the most demanding markets we work in. The salt air off Biscayne Bay, the concrete block construction, the Art Deco districts with preservation rules, and the insurance carriers that reward opening protection all shape how we approach a project here. We do not sell from a catalog and figure out the details later. We know a 1960s CBS house in Coral Gables needs custom bucks and lintel work before a PGT WinGuard casement anchors correctly. We know a unit with Florida Product Approval but no Miami-Dade NOA will fail inspection and cost the homeowner a full tear-out. That local knowledge is the difference between a job done once and a job done twice.
We are owner-operated, and Ed Winslow is the person accountable for every install. We publish our address and license number. Every technician is background-checked and arrives in uniform. When you call, a live person answers, 24 hours a day. No call center. No voicemail loop. For Miami homeowners who have been burned before by vague estimates or no-show crews, that is the whole point of working with the one down the road.

Our Window Replacement Services in Miami
Full Frame Replacement in Miami
Full frame replacement means the entire existing window is removed down to the rough opening, including the frame, sash, and trim. In Miami, this is often the only option that works, because the old aluminum frames on 1950s through 1980s CBS homes are frequently corroded from salt air or not deep enough to accept an HVHZ-rated impact unit. We pull the old frame, assess the concrete opening, fabricate any needed bucks, and install the new window with anchoring that meets Miami-Dade design pressure requirements. Full frame replacement is the upgrade path when you want maximum energy efficiency, the largest glass area, and a unit that passes inspection the first time. Ed Winslow signs off on every one.

Insert Window Replacement in Miami
An insert replacement, sometimes called a pocket replacement, leaves the existing frame in place and fits a new window inside it. For Miami homeowners whose frames are still square and sound, this is a faster and more affordable route to an energy-efficient or impact upgrade. That said, an insert is never the right call if the frame has hidden corrosion or was installed out of square. We measure, inspect, and tell you straight whether an insert will carry the wind load in your specific Miami-Dade zone or whether a full frame replacement is what the opening actually needs. Upfront pricing, either way. No surprises on the invoice.

Vinyl Replacement Windows in Miami
Vinyl replacement windows have become a workhorse in Miami because they resist salt corrosion far better than standard aluminum, carry excellent energy ratings, and can be ordered in impact configurations that meet HVHZ standards. We are authorized installers for brands including PGT, Therma-Tru, and Mr-Glass, and we guide you toward the vinyl or vinyl-clad units that make sense for your specific exposure. A home off Biscayne Boulevard in the MiMo district and a house on a quiet North Miami Beach street do not need the same finishes or design pressures, and we quote accordingly. Marine-grade hardware is our baseline expectation near the water, not an upsell.

Energy-Efficient Upgrade in Miami
Energy-efficient windows in Miami do two jobs at once: they cut the cooling load in a city where air conditioning runs ten-plus months a year, and they qualify you for real money back through wind-mitigation credits and the federal 25C energy credit. Low-E glass, argon fills, and thermally broken frames are standard options we install every week. For a 1970s CBS home in Westchester or a 1950s ranch in Shenandoah, replacing leaky jalousies with a properly rated low-E impact unit changes the indoor comfort immediately, and the FPL meter will notice. We will show you the spec sheets before we order anything. You will know exactly what you are buying.
If you are comparing options, our Window Replacement team can walk you through inserts versus full frame, brand differences, and lead times before you commit to anything.

Trusted Brands We Service in Miami
We are authorized installers for PGT, Mr-Glass, and Therma-Tru, among others, and we stock the Miami-specific hardware and components these systems need in this climate. That matters here: a standard aluminum extrusion that works in Orlando will begin pitting within a couple of years of Biscayne Bay salt air. We order PGT WinGuard and other HVHZ-listed units with marine-grade anodized or vinyl-clad frames as the default near the coast. Because we pre-order NOA-certified impact units ahead of the spring demand surge, our Miami customers are not sitting out hurricane season waiting on glass that never arrives. Eight authorized brands. One accountable company. Call (727) 483-7883 and we will help you pick the right one for your openings and your wind zone.
Common Window Replacement Problems We See in Miami Homes
- Florida Product Approval units that are not Miami-Dade NOA-certified. This is the most expensive mistake we see. A window sold legally in Broward or Palm Beach Counties can fail Miami-Dade inspection outright, forcing a full tear-out and reorder. We only specify NOA-listed units for Miami addresses.
- Original jalousie windows on older CBS homes. Jalousie, or louvered glass, is prohibited in new Miami-Dade construction because the slats can be popped out by hand and offer zero wind resistance. Retrofitting these openings requires custom bucks, proper anchoring, and often new lintel reinforcement.
- Corroded aluminum frames near Biscayne Bay and the Atlantic. Salt-laden air eats standard aluminum extrusions and hardware in just a few years. We use marine-grade anodized or vinyl-clad frames on every coastal Miami install, not as an add-on, but as the default.
- Waiting until June to order impact windows. The June through November hurricane season creates a demand surge that begins in March. Homeowners who order late in spring routinely see lead times stretch months because NOA-certified glass gets allocated to early pre-orders. We build schedules around this reality.
Pricing for Window Replacement in Miami, FL
Here is what Miami homeowners should expect to pay, per opening, installed. Impact windows generally run $800 to $1,500 per window. An impact single-hung lands in the $900 to $1,800 range. Large or custom openings, such as a wide picture window facing Biscayne Bay or a floor-to-ceiling configuration in a modern Edgewater condo, typically run $2,500 to $5,000. Whole-home packages across a 1950s CBS ranch in Coral Gables or a 1970s split-level in Kendall usually land between $8,000 and $25,000 and up, depending on opening count, frame material, and wind zone. What moves the price in Miami specifically: whether the opening is masonry or wood-framed, the floor height, which window types you choose, and whether we are doing a full frame replacement versus an insert. Impact units with the Miami-Dade NOA certification cost more than non-impact or non-NOA alternatives, and that premium is not optional in this county. Call (727) 483-7883 and we will measure every opening, give you a line-item written quote, and fix the price in writing before we order a single unit.
What Window Replacement Costs in Miami
You have seen the ranges above, and here is the honest context. A whole-home impact package in Miami-Dade is rarely driven by labor cost. It is driven by product certification, lead times, and structural retrofit work. Custom PGT WinGuard casements for a concrete-block home in Coral Gables mean fabricating bucks, possibly installing new lintels, and anchoring into masonry. None of that is standard wood-frame rough-opening work. Insert vinyl replacements on a newer home run lower; full frame retrofit on a 1962 CBS ranch runs higher. The key is that the price gets fixed in writing before we order. You will see every line item. Call (727) 483-7883 for a free in-home measure and a written quote that does not move.

Florida Pays You Back
The incentives stack, and Miami homeowners are in the best position to make the financial case. The My Safe Florida Home program has offered matching grants up to $10,000 for qualifying wind-mitigation upgrades, which includes impact windows and doors where state funding is available. Florida also has a sales-tax exemption on impact-resistant windows and doors. On top of that, the federal 25C energy credit can return 30% of the product cost on qualifying energy-efficient units, up to $600 per year. Then there is the windstorm premium credit: in Miami-Dade, a wind-mitigation inspection typically costs $75 to $150, and the resulting credits average around 25% on the windstorm portion of the premium. Citizens Insurance and private carriers here offer some of the largest opening-protection discounts in the state. We will not promise you a specific number. Your carrier sets that. We will tell you what to ask for and help you document every qualifying upgrade. Call (727) 483-7883 and we will walk through it.

One comparison worth making before you decide: impact windows versus hurricane shutters. Shutters protect the opening during a storm only if someone is home to deploy them, and they do nothing for energy efficiency, salt-air corrosion, or daily security. Impact windows are permanent protection. Nothing to hang, nothing to store, nothing to forget. For a Miami homeowner, impact windows also raise the appraisal value of the house and feed directly into the insurance premium reductions described above. A shutter protects on a handful of nights a year. An HVHZ-listed impact window works every single day.
The High-End Tier: Architectural Work in Miami
Miami’s high-end window replacement market is different from most of Florida. In the Miami Beach Architectural District, replacing windows in a contributing Art Deco or Mediterranean Revival building means the Miami Beach Historic Preservation Board signs off, and that board requires new units to replicate original sight lines, muntin profiles, and frame depths. You cannot install a standard off-the-shelf impact window and call it done. You need custom-fabricated impact-rated windows that satisfy HVHZ wind-load standards and historic aesthetics at the same time. Almost no standard impact window manufacturer stocks that combination. We coordinate directly with designers and architects, handle the submittals, and source the custom fabrication.
On this tier, lead times set the calendar, not labor. Custom fabrication for NOA-certified architectural units typically runs four to six weeks once drawings are approved. If a designer or architect is involved, their approval cycle adds time on the front end. We lay all of that out in week one and fix the price in writing before ordering. Our Window Replacement in Miami work spans everything from a modest condo insert to a fully custom geometric window package in a preservation district.
One recent project shows how this works in practice. We retrofitted a 1962 CBS ranch in Coral Gables whose original jalousie windows are now banned under current code. Our crew removed the louvered sashes, fabricated custom bucks to anchor PGT WinGuard casements into the concrete openings, and installed new lintels to meet design pressure requirements. The entire order was pre-booked by March to avoid hurricane-season backlogs. The homeowners went from windows you could pop out with a screwdriver to HVHZ-listed impact units that their insurance carrier credited immediately. That is the job done the way it is supposed to be done in Miami-Dade.

FAQs - Window Replacement in Miami
In Miami-Dade County, every replacement window and door in a residential condo must carry a Miami-Dade NOA, or Notice of Acceptance. Florida Product Approval alone is not sufficient here, regardless of building height. If a contractor installs an FPA-only unit in a Miami condo, the county will not pass the inspection, and the unit must be removed and replaced with an NOA-listed product. Always confirm the NOA number matches the exact window configuration before ordering. Call (727) 483-7883 and we will verify it for you before any deposit changes hands.
Rarely as-is. A jalousie, or louvered, window leaves an opening that is usually too shallow and too irregular for a standard impact unit. In a masonry CBS wall, the fix involves removing the old frame entirely, fabricating custom bucks to create a proper rough opening, and often installing new lintels above the opening to carry the structural load. We do this work in-house on Miami CBS homes. The result is an HVHZ-compliant impact window anchored correctly into concrete, not a window screwed into old wood trim. Call (727) 483-7883 for a free assessment of your specific openings.
A wind-mitigation inspection, typically $75 to $150, documents your new impact-rated openings, and the resulting credits average around 25% on the windstorm portion of the premium. In Miami-Dade’s catastrophic insurance market, that is frequently the difference between a manageable policy and a four-figure annual increase. We have seen homeowners in Coral Gables and Westchester cut thousands in annual premium costs after a full impact retrofit. Your carrier sets the final number, not us. We document every product with the NOA number, design pressure, and installation photos so the inspection is clean. Call (727) 483-7883 for guidance on what to submit.
Miami sits between Biscayne Bay and the Atlantic, and the salt-laden air travels well inland. Standard aluminum extrusions and hardware corrode and pit within two to three years of constant exposure, even in neighborhoods like Shenandoah, Little Havana, or West Flagler that are miles from the ocean. The salt is airborne and relentless. We default to marine-grade anodized aluminum or vinyl-clad frames on Miami installs, because anything less means you will be replacing hardware, if not whole frames, far sooner than you should. Call (727) 483-7883 and we will spec the right finish for your exact exposure.
Yes, and it is a specialty of ours. The Miami Beach Historic Preservation Board requires replacement windows in contributing Art Deco and Mediterranean Revival buildings to replicate original sight lines, muntin profiles, and frame depths. That means custom-fabricated impact-rated windows that meet HVHZ wind-load standards and the board’s aesthetic requirements simultaneously. Almost no standard impact window manufacturer stocks that combination off the shelf. We handle the custom fabrication, the drawings, and the board submittal. Call (727) 483-7883 to schedule a consultation for your building.
