Fast, Reliable Window Replacement Across North Miami
Window replacement in North Miami usually means one thing: pulling out old jalousie windows and putting in impact-rated glass that passes Miami-Dade code. A full-frame jalousie-to-impact conversion on a typical 1950s CBS home runs $1,200 to $2,400 per opening, installed. We’ve done hundreds of these jobs across North Miami, from Keystone Islands to the neighborhoods along NE 125th Street, and we know exactly what’s behind those old louvered frames before we open the wall. Call (727) 604-9322 and we’ll walk you through what your house actually needs.

Why Winslow Windows & Doors Is North Miami’s Preferred Window Replacement Company
Ed Winslow started this company in 2011, and his name is on the door, on the license, and on every job we do. That’s not a slogan. When a North Miami homeowner calls with a question about their impact windows, they get a live person on the phone, not a voicemail loop. Our techs roll into neighborhoods like Arch Creek East and Sans Souci in uniform, background-checked, and ready to explain what we’re seeing before we touch anything.
We’ve worked on enough North Miami homes to know what the block walls hide. Contractors from wood-frame suburbs often miss what’s happening inside a 1960s CBS rough opening. We don’t, because we’ve spent over a decade cutting into these exact walls across North Miami and the rest of Miami-Dade. When a homeowner on NE 135th Street needs a Window Replacement team that understands HVHZ anchoring, that’s who we are.
Our Window Replacement Services in North Miami
Full Frame Replacement
On North Miami’s concrete block homes, full frame replacement means removing the entire existing window, including the aluminum buck embedded in the masonry. We cut the old metal out, treat the block, install new anchored framing, and set the impact unit into a Miami-Dade NOA-approved opening. You don’t want a tear-out-and-replace job done by a crew that has only worked on wood studs. North Miami’s housing stock demands specific fasteners, specific flashing, and specific inspection experience. We bring all three.

Insert Window Replacement
If your existing frames are still structurally sound, an insert replacement can save you money and wall disturbance. We measure the existing opening, fabricate a new impact-rated unit to fit inside the old frame, and seal it against North Miami’s wind-driven rain. This works well on homes in the Sans Souci and Keystone Point areas where the original framing is still clean. Our Window Replacement in North Miami work always starts with a free inspection, so you’ll know whether a full tear-out is even necessary before you commit to a number.

Vinyl Replacement Windows
Vinyl makes sense on a lot of North Miami homes, especially where the budget doesn’t stretch to a full impact upgrade but you still need to stop the drafts coming through 60-year-old jalousies. We stock and install vinyl single-hung and casement units that carry current product approvals. One thing we’re honest about: vinyl alone won’t satisfy a Miami-Dade wind mitigation inspection. If you’re facing an insurance renewal deadline, we’ll tell you plainly whether vinyl gets you there, or whether you need impact-rated aluminum or vinyl impact units instead.

Energy-Efficient Upgrade
Replacing louvered jalousies with insulated impact glass changes how a North Miami house breathes. Jalousie panes leak air constantly. Insulated impact units with low-E coatings cut the solar load through the glass and seal the opening completely. In a city where air conditioning runs nine months of the year, that’s real money back on the FPL bill every month. ES Windows and ECO Window Systems both offer glass packages that meet Miami-Dade energy requirements, and We can walk you through both regularly in North Miami.

Common Window Replacement Problems We See in North Miami Homes
- Corroded aluminum bucks inside block walls. North Miami’s 1950s and 60s CBS homes have window frames set into aluminum channels embedded in the concrete. After 50-plus years of humidity and, near the bay, salt air, those channels rust through. A window installer who doesn’t remove them is setting you up for water intrusion you’ll never see until the drywall stains.
- Jalousie windows flagged by insurance carriers. We get calls every week from North Miami homeowners holding a letter from their insurer stating the policy won’t renew unless all non-impact openings are replaced. This is the single biggest driver of our work in North Miami, and it means families are on a hard deadline, not browsing.
- Florida Product Approval without a Miami-Dade NOA. North Miami sits inside the High Velocity Hurricane Zone. A unit approved under the statewide code but not by Miami-Dade County will not pass a local permit inspection. We see homeowners burned by this on a regular basis, usually after buying windows online or from an installer whose main business is outside the county.
- Undersized framing when openings get enlarged. Going from a narrow jalousie to a wider double-hung or casement means the header above the opening has to carry more load. On CBS construction, that’s an engineered fix, not a guess. We’ve had to rebuild openings where a previous contractor just cut the block wider and left the old lintel in place. The sashes sagged within a year.
Pricing for Window Replacement in North Miami, FL
Here’s the honest picture for North Miami. A single impact single-hung replacement typically runs $900 to $1,800 per window, installed. A full-frame jalousie-to-impact conversion on a CBS home runs $1,200 to $2,400 per opening because we’re removing the old buck, treating the block, and installing new anchoring to Miami-Dade NOA standards. Large or custom openings, like a picture window facing Biscayne Bay, land between $2,500 and $5,000. Whole-home packages for a three-bedroom 1960s North Miami ranch typically fall between $8,000 and $25,000 depending on unit count and glass package. The free in-home measure and written quote we provide is line-item, fixed, and doesn’t change unless you approve a change order in writing. Call (727) 604-9322 to book it.
What Window Replacement Costs in North Miami
North Miami pricing moves on four things: how many openings you’re doing, whether it’s a new-construction or full-frame tear-out, the wind zone rating you need, and how high off the ground the window sits. Impact windows in North Miami generally run $800 to $1,500 per window installed for standard openings. Impact single-hung units run $900 to $1,800. If you’re converting jalousies to a larger casement or double-hung, the structural work on the block opening pushes the number up. Whole-home impact packages on North Miami’s 1960s CBS inventory run $8,000 to $25,000 and up depending on count and brand. We give you a written, line-item price after a free in-home measure. No change orders unless you sign off first.
Florida Pays You Back
There are three places North Miami homeowners can recover money on this work. The My Safe Florida Home program matches up to $10,000 for qualifying wind-mitigation upgrades, including impact windows, for homes that pass the initial inspection. Florida also exempts impact-resistant windows and doors from sales tax, which saves you around 6 to 7 percent immediately. On federal taxes, the 25C energy credit covers 30 percent of the product cost, up to $600 per year, on qualifying energy-efficient units. After installation, a wind mitigation inspection in North Miami (about $75 to $150) typically produces a windstorm premium credit averaging around 25 percent on the windstorm portion of your homeowner’s policy. Insurance carriers and program administrators set the final numbers, so we never guarantee a specific refund, but we’ll point you to the paperwork for every one of these.

FAQs - Window Replacement in North Miami
Because jalousie glass louvers are not impact-rated and cannot pass any Miami-Dade HVHZ wind-load standard. Insurers view every jalousie opening as a guaranteed breach point in a hurricane, and they’ll typically non-renew a policy rather than accept that risk. Replacing them with Miami-Dade NOA-approved impact units is the only fix that satisfies the carrier. We help with the paperwork once the install is complete. Call (727) 604-9322 if you’re holding a non-renewal letter.
A Miami-Dade Notice of Acceptance is product approval specific to the High Velocity Hurricane Zone and is a stricter testing standard than Florida’s statewide product approval. North Miami’s building department requires an NOA for every window and door installed. A unit with only a Florida Product Approval will fail inspection here and leave you with non-compliant openings. We only install units with current Miami-Dade NOAs for North Miami jobs.
We cut out the original aluminum buck entirely, clean and treat the concrete block, then anchor the new impact frame with stainless steel fasteners sized for the wind load. Skimming over the old metal or leaving it in place is how hidden water intrusion starts. Most crews from outside Miami-Dade have never opened a 1962 CBS wall. We do it weekly in North Miami. Call (727) 604-9322 for a free inspection and an honest read on your openings.
Yes. Original jalousies leak conditioned air constantly and let solar heat straight through uncoated glass. Sealed, insulated impact units with low-E coatings cut both the air leakage and the radiant heat load. Homeowners in North Miami regularly report cooling bills dropping 15 to 25 percent after a full jalousie-to-impact conversion. The exact number depends on the home’s orientation and how much of the glass faces east or west.
You’ll likely lose your windstorm insurance credit, and on renewal, your carrier may either raise the windstorm premium substantially or refuse to renew the policy at all. The fix is replacing every non-impact opening with Miami-Dade NOA-approved units and then rescheduling the inspection. We carry the product approval numbers for every configuration we install, and we’ll hand you the paperwork the inspector needs. Call (727) 604-9322 to schedule a free in-home measure and get the process moving.
Opening Up a 1950s North Miami Wall Changes Things
Here’s what actually happens on a North Miami jalousie conversion. The jalousie comes out, and behind it is the original aluminum buck, a channel of metal set into the block when the wall was poured six decades ago. In most homes we open, especially east of NE 15th Avenue and anywhere near Keystone Islands, that buck has been degrading for years. Salt air accelerates the corrosion. So does the constant humidity against bare aluminum. Once the metal is compromised, water moves through the block around the window, and you won’t see it until interior paint blisters or drywall softens.
Our crew recently replaced twelve jalousie windows on a 1962 CBS home near Keystone Islands. Salt-air corrosion had seized the original frames, so every single one had to be chiseled out. During tear-out, we found embedded aluminum bucks rusted through in multiple openings. We cut out the old metal, treated the block, and anchored PGT impact-rated casements with stainless steel fasteners and a Miami-Dade NOA-approved flashing system before reinstalling the interior jamb extensions. This is not a job you can do by swapping panes. It’s masonry work, and it’s why we inspect every opening before we quote.
The other thing that changes once the wall is open is what the code inspector sees. Enlarging a jalousie opening for a double-hung means the header and king studs have to be brought up to current Miami-Dade engineering standards. Undersized framing in a 60-year-old wall sags within a season and the sashes stop operating. We handle this with an inspection-first approach. Our quote includes the visible work and a written allowance for the things we can’t see until the block is open. If the scope changes, you get a written change order and you approve it before we proceed. No one on our crew has ever been authorized to work off a handshake. Ed Winslow’s name is on the door, and we don’t let a North Miami homeowner get surprised on an invoice.
North Miami’s original jalousie windows aren’t just non-compliant. Their removal almost always exposes what’s been hiding in the wall since the Eisenhower administration. A contractor who treats this like a suburban vinyl swap is going to leave you with water in your walls and a failed inspection. Ask anyone in North Miami who’s done this job right, and they’ll tell you the same thing: the window is only half the job. The buck, the block, and the flashing are the other half.
Impact Windows vs. Hurricane Shutters in North Miami
Shutters stop the glass from breaching, but only if you’re home to deploy them, and only if they’re maintained and installed correctly. Impact windows are permanent protection, no panels to hang, no tracks to corrode, and no late-night scramble ahead of a storm. They also cut outside noise and lower cooling bills every single day, not just during the three days a year the shutters matter. For a North Miami homeowner on a busy street like NE 125th or near the causeway traffic, the daily noise reduction alone often justifies the upgrade.
