Fast, Reliable Sliding Glass & Patio Doors Across North Miami
Sliding glass and patio door replacement in North Miami typically runs $1,800 to $5,000 for a standard NOA-approved impact unit installed, with custom oversize openings reaching $7,500 or more. Most jobs in North Miami take one to two days once the new door arrives from the manufacturer, and custom fabrication generally runs four to six weeks. If you’re dealing with a seized track, a fogged pane, or a door that no longer locks properly, call (239) 310-4121 and we’ll get a real person on the line.
North Miami homes are different from anything you’ll find in other parts of South Florida. The concrete block and stucco construction from the 1950s through the 1970s was built around jalousie windows and thin aluminum sliders that were never designed for today’s hurricane codes. We know what’s behind those walls because we’ve opened enough of them. When you work with Winslow Windows & Doors, you’re working with a local crew that understands exactly what a permitted patio door replacement in North Miami entails, from the first measurement to the final county inspection.
Why Winslow Windows & Doors Is North Miami’s Preferred Sliding Glass & Patio Doors Company
Ed Winslow founded this company in 2011, and his name is still on every job we do. We’re not a franchise outfit with a rotating cast of subcontracted installers. Our technicians are background-checked, uniformed, and they arrive in a marked truck. You’ll know who’s walking up your driveway before they knock.
North Miami homeowners call us because we answer the phone. Not a call center, not a voicemail loop. A live person picks up, 24 hours a day, seven days a week. If a sliding door won’t close at 11 p.m. and you’re worried about security, you’ll talk to someone who can actually help.
We also understand the paperwork side of North Miami better than most. Every sliding glass door we install carries a Miami-Dade County Notice of Acceptability, or NOA. That’s non-negotiable in the High Velocity Hurricane Zone, and we don’t bend on it. We pull permits, we schedule inspections, and we stand behind the work with our Done Right Promise. If it’s not done right, we come back and make it right. That’s a lasting standard, and Ed’s name is on it.

Our Sliding Glass & Patio Doors Services in North Miami
Impact Sliding Glass Door Replacement
The majority of our North Miami work is replacing original aluminum sliders with Miami-Dade NOA-approved impact units. Homes along the canal streets near Keystone Point and the residential blocks off Biscayne Boulevard were built when louvered jalousie windows and thin sliders were the builder’s default. Those couldn’t pass a wind-load test today. We remove the old unit, assess the rough opening, reframe where needed, and set a PGT, CGI, CWS, or ViewLux impact door that will actually hold up in a storm.

Patio Door Track and Hardware Repair
Salt air does a number on aluminum hardware in North Miami. We regularly replace pitted, seized rollers on doors within a few miles of Biscayne Bay, and on canal-front streets near the Keystone Point border the corrosion shows up in as little as ten years. If your door drags, jumps the track, or won’t latch, we can usually rebuild the hardware without replacing the whole unit, assuming the glass and frame are still sound.

Custom Rough-Opening Framing for Old Jalousie Openings
This is the part of the job most companies don’t mention until the wall is open. North Miami’s 1950s to 1970s CBS homes often have non-standard rough openings framed for louvered jalousie panels, not a modern sliding door. You can’t just drop a PGT impact slider into that opening. We reframe, add a proper header, and flash the opening correctly before the new door goes in. The allowance for this work is written into our contract up front, so you’re not blindsided by a change order.

Sliding Glass Door Installation for New Openings and Room Additions
Creating a new opening between a living room and a patio, or adding a slider to a new addition in the Keystone Islands or along the Arch Creek corridor, means cutting into concrete block and installing a lintel. We handle that, too. The new door still needs to meet HVHZ design pressures for its specific floor height and exposure, and we match the glazing and frame configuration to the opening’s exact wind-load requirements.
Looking for a deeper look at the full range of what we do? Our Sliding Glass & Patio Doors team handles everything from track repairs to full impact retrofits across Miami-Dade County.

Trusted Brands We Service in North Miami
Winslow Windows & Doors is an authorized installer for PGT, CGI, CWS. We’re not a broker passing your order to a third party. We order the units directly from the manufacturer with the exact Miami-Dade NOA configuration your home needs, and our crew installs them. That means when a warranty question comes up, or a part needs to be ordered, you’re dealing with the people who did the work, not a ticket number in another state.
Common Sliding Glass & Patio Doors Problems We See in North Miami Homes
- Salt-air corrosion on aluminum tracks and rollers. North Miami sits a few miles inland from Biscayne Bay and the Atlantic, and the salt spray doesn’t stop at the coastline. We see original aluminum slider tracks pitted and seized within 10 to 15 years, especially on canal-front streets near Keystone Point. Stainless fasteners and corrosion-resistant finishes aren’t an upgrade here, they’re the bare minimum.
- Non-HVHZ sliders installed by previous owners. Contractors working along the waterfront-canal streets near the Keystone Point border frequently find that homeowners previously purchased windows and sliders with a Florida Product Approval, but no Miami-Dade NOA. That’s a problem. When a permit is pulled for any work on the house, the county can require those non-compliant units to be removed and replaced before a certificate of occupancy is issued.
- Undersized or deteriorated wood framing around old patio doors. Once we open up a wall on a 1960s concrete block home in North Miami, the framing around the old patio door is often undersized, water-damaged, or both. Original headers were sometimes slapped together from scraps. When a new impact-rated door has to meet a design pressure of +/-100, that framing has to be rebuilt properly.
- Failed waterproofing and flashing. The original flashing around patio doors in 50-to-70-year-old North Miami homes is often cracked, rusted, or missing entirely. If you’ve got water stains on the interior wall near your slider, that’s usually the culprit. We pull the old door, inspect the sill, replace the flashing, and seal the new opening correctly before the new unit goes in.
What Sliding Glass & Patio Doors Costs in North Miami
A standard NOA-approved impact sliding glass door in North Miami runs $1,800 to $5,000 installed. Larger custom openings, multi-slide configurations, and doors on upper floors with higher wind-load design pressures can push into the $7,500 range. Whole-home packages that include every window and door typically land between $8,000 and $25,000, depending on the size of the house and the number of openings.
What moves the price in North Miami specifically:
- Opening count and size. Every opening is a separate permit line item, a separate NOA configuration, and a separate labor unit.
- Wind zone and floor height. HVHZ design pressures increase with building height and exposure. A third-floor condo slider on Biscayne Boulevard has different requirements than a ground-floor door on a residential street near NE 125th.
- Frame material. Aluminum, vinyl, and impact-rated configurations all carry different material costs. PGT and CGI units run at different price points than ViewLux or CWS.
- What’s behind the wall. If we open the rough opening and find jalousie framing, rotted wood, or non-structural mess, there’s framing work involved. We write an allowance for that into the contract up front and price any discovery in writing before we touch it.
You’ll get a free in-home measure and a written line-item quote before any work starts. No vague verbal numbers, no change orders you didn’t approve. Call (239) 310-4121 to schedule yours.

Florida Pays You Back
Replacing sliding glass doors and windows in North Miami qualifies for a few state and federal incentive programs worth knowing about. None of them are guaranteed, but they stack when they apply. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades on primary residences. Florida also exempts impact-resistant windows and doors from sales tax, which shaves real money off a multi-door project. The federal 25C energy credit covers 30% of the product cost on qualifying units, up to $600 per year. And after a wind-mitigation inspection, which runs $75 to $150, many homeowners see windstorm premium credits averaging around 25% on the windstorm portion of their policy. Your insurance carrier has the final say on premium credits, but the inspection is the first step.
Opening Up an Older North Miami Home: What We Actually Find
North Miami requires every sliding glass and patio door replacement to carry a Miami-Dade County Notice of Acceptability under the High Velocity Hurricane Zone code. That’s among the strictest product-approval standard in the United States. It’s not a suggestion and it’s not something you can waive. The problem is that many original CBS homes built between 1950 and 1975 in North Miami still have non-standard rough openings framed for louvered jalousie panels, not a modern sliding glass door. You cannot set a NOA-approved impact slider into a jalousie opening without framing work. Period.
Here’s what that means in practice. When our crew opens up the wall around an old patio door in North Miami, we’re looking for three things: undersized or water-damaged framing, failed original flashing, and wiring that was never meant to be near a new structural opening. Old 1960s wiring often runs through the same cavities we need to reframe, and when a permit is pulled, the county inspector can require that outdated wiring be brought up to code before the wall gets closed back up. That’s not us looking for extra work. That’s the code doing its job.
Our approach is built around inspection first. Before we write the contract, we look at the door, the surrounding wall, the condition of the subfloor and sill, and any visible wiring or plumbing in the area. We write allowances for framing, flashing, and unforeseen conditions directly into the contract. If something unexpected shows up once the wall is open, we photograph it, explain it, price it, and get your written approval before we touch it. No surprise change orders. No pressure.
Why Proper Rough-Opening Framing Matters in North Miami
On a canal-front street near Keystone Point, our crew removed a corroded original aluminum slider that had seized mid-track. The homeowner had lived with the door for years, forcing it open and shut by leaning into it. When we pulled the unit, the rough opening was framed for louvered jalousie panels and had no header at all. The door had been holding up the wall above it, not the other way around.
We reframed the opening to hold a PGT impact-rated glazing unit, used stainless fasteners throughout, and closed up the wall with new flashing and a low-E insulated glass unit before the county inspector came back. The total cost was higher than the initial quote, but it wasn’t a surprise. The allowance language was in the contract from day one, and the homeowner approved the additional scope in writing before we cut another stud. That’s how a permitted retrofit in North Miami should go.

FAQs - Sliding Glass & Patio Doors in North Miami
No. A Florida Product Approval is a statewide certification, but North Miami sits inside the High Velocity Hurricane Zone, which requires a Miami-Dade County Notice of Acceptability for every window and door. If a permit is pulled for any work on the house, the inspector can flag non-NOA units and require their removal before signing off. You won’t get a certificate of occupancy with those units in place. Call (239) 310-4121 to find out if your existing doors meet the NOA standard, estimates are free.
Because the original opening was framed for louvered jalousie panels, not a modern sliding glass door. The jalousie opening is narrower, taller, and often has no structural header across the top. A new impact-rated slider needs a proper header, king studs, and jack studs to carry the wind-load design pressure required in the HVHZ. That framing work has to be done before the door goes in. Call (239) 310-4121 and we’ll tell you what your specific home needs, with a written quote before you commit.
We inspect the wall cavity before we write the contract, and we include allowance language for framing, flashing, and unforeseen conditions. If we find something once the wall is open, we photograph it, explain it, price it, and wait for your written approval before we proceed. Outdated wiring is common in 1950s to 1970s North Miami homes, and when a permit is pulled, the county inspector can require it be brought up to code before we close the wall. You’ll know the price of that work before it happens.
Yes. Impact-rated doors with low-E insulated glass units block a significant portion of solar heat gain, which reduces the load on your air conditioner. North Miami’s combination of heat, humidity, and months of direct sun makes windows and sliding doors the biggest thermal weak points in an older CBS home. The federal 25C energy credit covers 30% of product cost on qualifying units, up to $600 per year. Call (239) 310-4121 to talk about which glazing options make sense for your home.
Many carriers in Florida offer windstorm premium credits after a wind-mitigation inspection verifies that every opening carries a Miami-Dade NOA. The inspection runs $75 to $150, and homeowners often see windstorm premium credits averaging around 25% on the windstorm portion of their policy. Your insurance carrier sets the final number, not us. But the full replacement of all NOA-approved impact units is the strongest position you can put your home in with an insurer.
