AfterStorm & Exterior Doors in Miami, FL
Door Installation services in Miami means putting a product between your home and a hurricane – and getting that wrong has real consequences. At Winslow Windows & Doors, we install impact-rated storm and exterior doors that meet Miami-Dade County’s NOA (Notice of Acceptance) requirements, sized and set correctly for South Florida’s building codes, and backed by our 36500-Day Done Right Promise. If you need a new front entry, a reinforced side door, or a full exterior door replacement before the next named storm rolls through, call us at (863) 862-5435 – a live person will pick up, any hour of the day.
Miami homeowners don’t have the luxury of treating their exterior doors as an afterthought. A door that fails during a storm isn’t just a property damage problem – it’s a structural one. Once the envelope of your home is breached, wind pressure builds inside and can lift the roof. We’ve been doing this work since 2011, and Ed Winslow has seen what happens when the wrong door gets put in a Miami frame. Our job is to make sure that’s not your story.
Our storm and exterior door work falls under our broader Door Installation in Miami service – but this page focuses specifically on exterior entry and storm doors: the products designed and rated for South Florida’s wind zones, the installation details that determine whether a door holds or fails, and what you should expect to pay in today’s Miami market.
When You Need Storm & Exterior Doors
- Your current door is not Miami-Dade NOA-certified. If your home was built before 2002 or your door was never upgraded after Hurricane Andrew reshaped Florida’s building code, there’s a real chance your exterior door doesn’t meet current Miami-Dade wind load requirements. That’s a code issue and a safety issue wrapped in one.
- You’re seeing daylight, drafts, or water intrusion around the frame. In Miami’s wet season, even a small gap at the threshold or along the door jamb lets water track in. We’ve pulled out doors in Kendall and Hialeah where the frame was rotting from the inside out because the original weatherstripping had failed years earlier and nobody noticed until the drywall started showing stains.
- Your door binds, sticks, or won’t latch properly. Miami’s humidity and heat cause wood frames and even some composite frames to swell and shift. A door that doesn’t latch fully is a security issue on a calm Tuesday and a catastrophic failure point during a tropical storm.
- You’re replacing windows with impact glass and want the door to match. There’s no point hardening your windows if the front door is a standard residential unit. The weakest point in your home’s exterior envelope is the one a storm finds first.
- You’re getting a home insurance review or trying to qualify for a windstorm mitigation credit. Miami-area insurers regularly inspect and may require documentation showing your exterior doors are impact-rated. An upgrade to a NOA-certified storm door can reduce your premium – and we provide the documentation you need.
- The existing door is 15 or more years old and showing its age. Fading, warping, peeling, or hardware that’s corroded from Miami’s salt air are all signs a door is nearing the end of its useful life. Waiting until after a storm to replace it means replacing it under pressure, often at a worse price.
Our Storm & Exterior Doors Process
- Free on-site estimate and code review. We come to your home – no trip charge inside Miami-Dade County – measure the rough opening, check the existing frame condition, confirm your wind zone classification, and walk you through what products are NOA-approved for your specific application. You get upfront pricing before we schedule anything. No surprises on the invoice.
- Product selection and permit pulling. We’ll help you choose from our authorized lineup – brands like Therma-Tru and ES Windows carry product lines specifically engineered for Florida’s high-velocity hurricane zone (HVHZ). We pull the permit with Miami-Dade’s building department on your behalf. This step protects you: unpermitted door installations can complicate insurance claims and home sales.
- Old door and frame removal. Our background-checked, uniformed crew removes the existing door and assesses the rough opening. In older Miami homes – particularly those built in the 1960s and 70s in neighborhoods like Westchester or Coral Gables – we sometimes find frame rot or damaged buck material that needs to be addressed before a new door can be properly set. We tell you what we find before we proceed.
- Buck preparation and waterproofing. Miami’s driving rain means waterproofing the rough opening isn’t optional. We apply flashing tape and sealant at the sill and jambs before the new door goes in. This is the step that separates a door that stays dry for 20 years from one that starts leaking in year three.
- Installation and hardware setting. The door unit is set, shimmed, and anchored to the structural buck per Miami-Dade installation requirements. Anchor spacing for impact-rated doors in South Florida’s HVHZ is more demanding than standard residential installation – our crew knows the specs and follows them. We set the hardware, test the latch and deadbolt, and check the sweep seal at the threshold.
- Inspection and sign-off. Miami-Dade requires an inspection on permitted door work. We coordinate the inspection schedule and walk the inspector through the job. When the permit closes, you have a paper trail showing the door was installed correctly – valuable for your insurance file and any future buyer’s due diligence.
Storm & Exterior Doors Pricing in Miami
Storm and exterior door replacement in Miami typically runs between $1,200 and $4,500 installed, depending on the door type, size, glass content, and frame conditions found at installation. That range covers the most common residential scenarios – a single impact-rated fiberglass entry door at the low end, and French & Double Doors with decorative glass lites and new hardware at the upper end.
| Door Type | Typical Installed Range (Miami) |
|---|---|
| Single impact fiberglass entry door (standard 3/0 x 6/8) | $1,200 – $2,000 |
| Single impact steel entry door | $1,100 – $1,800 |
| Double impact entry doors (fiberglass or steel) | $2,400 – $4,500 |
| Single entry door with decorative impact glass lites | $1,800 – $3,200 |
| Door only (owner-supplied), labor and permit | $600 – $1,100 |
| Frame rot repair / buck replacement (if needed) | $200 – $600 additional |
A few things move the number in Miami specifically. Salt air corrosion in coastal zip codes like Miami Beach, Key Biscayne, and Coconut Grove tends to accelerate frame deterioration, which means we find damaged bucks more often in those areas than in, say, Doral or Hialeah. Homes on the National Register or in historic districts – parts of Coral Gables and the Miami Design District – may have design review requirements that limit what products or profiles are allowed, which can narrow your options and affect cost.
If your repair or replacement comes to more than $200, our standing $40 off offer applies automatically – no coupon needed. Seniors and veterans always receive 10% off, and that discount doesn’t expire. Call (863) 862-5435 for a free estimate – we’ll give you a written number before any work begins.
Why Therma-Tru and ES Windows for Miami Storm Doors
Not every door brand bothers to engineer specifically for Florida’s HVHZ, which is the strictest residential wind load classification in the country. We recommend Therma-Tru’s Impact Collection fiberglass doors for most Miami entry door projects because the fiberglass skin resists the warping, swelling, and corrosion that Miami’s combination of humidity and salt air causes in wood and lower-grade steel units. Therma-Tru’s HVHZ-rated doors carry Miami-Dade NOA certification, which is the documentation your insurer and Miami-Dade’s building department both want to see.
For projects where the customer wants a door that matches an impact window package – particularly when we’re replacing both windows and exterior doors in the same project – ES Windows’ door products integrate well with their window line and carry the same NOA certifications. Keeping to a single manufacturer’s NOA documentation simplifies the permit file and the insurance submission.
Ed’s name is on the business, which means we’re not going to sell you a product we don’t believe in just because it’s cheaper to stock. When a door isn’t right for a Miami application, we say so.
What Makes Miami Different for Exterior Door Installation
Miami-Dade County sits entirely within Florida’s HVHZ. That designation exists because the county has experienced catastrophic wind events – most notably Hurricane Andrew in 1992, which caused engineers to completely rethink how building envelopes should be constructed in South Florida. The current Florida Building Code chapter that applies to new door installations here is more demanding than what applies in most of the rest of the country, and it’s more demanding than what applies even in Broward or Palm Beach counties.
Practically, that means a few things for your installation. The anchor pattern for impact-rated doors in Miami-Dade must follow Miami-Dade’s product approval specifications exactly – not just the door manufacturer’s general installation guide. The flashing and sealant details matter more here than they would in Atlanta or even Tampa. And the permit and inspection process is real: Miami-Dade’s inspectors are looking for proper anchor spacing, correct product approval documentation, and proper sealing. We’ve been through this process many times, including on homes in Sweetwater, Homestead, North Miami, and across Miami proper.
We also do this work in South Florida’s wet season, which means scheduling an installation during a stretch of afternoon thunderstorms. Our crew knows how to stage and sequence the work to protect your open rough opening if weather moves in during the job.
FAQs – Storm & Exterior Doors
Do exterior doors in Miami have to be impact-rated?
New exterior door installations in Miami-Dade County must comply with the Florida Building Code’s HVHZ requirements, which effectively means the door must have Miami-Dade product approval (an NOA) for the wind load zone of your property. Replacing an existing door with a like-for-like non-impact unit is not code-compliant for permitted work in Miami-Dade. If you’re selling the home, refinancing, or filing an insurance claim, an unpermitted or non-code-compliant door can create serious problems. Call (863) 862-5435 and we’ll confirm what’s required for your specific address – the estimate is free.
How much does a storm door installation cost in Miami?
A single impact-rated fiberglass entry door installed in Miami typically runs $1,200 to $2,000; double-door configurations with glass lites run $2,400 to $4,500. Those figures include the product, permit, and installation labor. Frame rot or damaged buck material discovered during removal adds $200 to $600 in most cases. We give you a written upfront price before the job starts, so there are no line items that appear on the invoice that weren’t in the estimate. Call (863) 862-5435 for a free on-site quote.
Can a storm door installation be done in one day?
Most single-door replacements in Miami are a one-day job for our crew – typically three to five hours for the removal, prep, installation, and cleanup, assuming the rough opening is in sound condition. If we find significant frame rot or need to repair the structural buck, that can add half a day. Double-door installations with new sidelites generally take a full day. We schedule permit inspections separately, which happens after installation – we coordinate that for you so you don’t have to navigate Miami-Dade’s inspection calendar yourself.
What’s the difference between a storm door and an impact door?
In Miami’s context, these terms often get used interchangeably, but they mean different things. A traditional “storm door” is a secondary door installed in front of an existing entry door – typically lightweight aluminum or steel, offering some weather protection but not rated for HVHZ wind loads. An “impact door” or “impact-rated exterior door” is a single unit engineered with laminated glass or solid impact-resistant panels and a reinforced frame, carrying Miami-Dade NOA certification for the full wind load. For Miami homes, we install Hurricane-Proof Front & Entry Doors – not the secondary storm door type – because those are what meet code and what actually protect the structure during a hurricane.
