AfterStorm & Exterior Doors in Miami, FL
Door Installation services in Miami means putting an impact-rated, code-compliant door between your home and whatever the Atlantic decides to send your way – hurricane-force winds, driving rain, and the kind of heat that warps an ordinary door frame within a few seasons. At Winslow Windows & Doors, we’ve been installing storm and exterior doors across Miami since 2011, and Ed Winslow’s name is on every job we do. Call us at (863) 946-5039 – a live person picks up, any hour of the day or night – or keep reading to understand exactly what this service involves and what it costs here in Miami’s market.
This page is part of our broader Door Installation in Miami service. If you’re still weighing your full exterior door situation – frame condition, sidelites, threshold replacement – that parent page covers the complete picture. Here, we’re focused specifically on storm doors, impact exterior doors, and the Miami code requirements that govern them both.
Miami-Dade County has some of the strictest impact and wind-load requirements in the country – stricter than most of Florida’s interior counties. A door that passes Florida Building Code elsewhere may not pass Miami-Dade Product Approval. We know the difference, we install products that carry the right approvals, and we pull the permits so you’re never left exposed at resale or after a claim.
When You Need Storm & Exterior Doors
Not every situation is an emergency, but a few are. Here are the clearest signs that your existing door needs to be replaced or upgraded to a proper storm or impact-rated exterior door:
- Your door wasn’t built to Miami-Dade’s impact standards. Many homes in Coconut Grove, Little Havana, and older Coral Gables neighborhoods have original wood or hollow-core doors that predate modern wind-load codes. These doors can fail in a Category 1 storm, let alone a major hurricane.
- You’re paying higher homeowner’s insurance than your neighbors. Miami insurers frequently discount premiums for homes with Miami-Dade-approved impact doors. If your door lacks that product approval, you’re likely leaving money on the table every renewal cycle.
- There’s visible daylight around the frame. If you can see light – or feel air – around the edges of a closed door, the frame has shifted, the weatherstripping has failed, or both. In Miami’s humidity, that gap is also an invitation for mold to get a foothold behind your trim.
- The door sticks, drags, or won’t latch cleanly after rain. Miami’s wet season runs May through October, and repeated soaking cycles cause wood frames to swell and composite doors to warp. A door that jams in July is a security problem, not just an annoyance.
- You’re selling or refinancing your home. Miami real estate inspectors flag non-impact exterior doors on homes in the High Velocity Hurricane Zone (HVHZ). Replacing the door before listing avoids a last-minute scramble and keeps your negotiating position intact.
- Your current storm door is aluminum-framed and decades old. Older aluminum storm doors in neighborhoods like Westchester and Kendall were installed before current energy codes. They transfer heat freely and offer minimal impact protection. Today’s options are in a different category entirely.
Our Storm & Exterior Doors Process
We don’t show up with a door and hope for the best. Every installation follows a repeatable sequence that keeps the job clean, the permit on file, and your home protected from day one.
- Free on-site measurement and assessment. One of our background-checked, uniformed technicians comes to your home, measures the rough opening, checks the frame and sill condition, notes any water damage or rot, and confirms which Miami-Dade-approved products will fit without a full frame rebuild. No trip charge inside Miami-Dade County. No pressure. You get a written, itemized quote before we leave the driveway.
- Product selection and Miami-Dade compliance check. We’ll walk you through Therma-Tru and ES Windows options that carry the Miami-Dade Notice of Acceptance (NOA) your home needs. We match the door to your opening size, wind-load zone, and aesthetic – whether you want a smooth fiberglass slab that looks like painted wood, or a flush steel door for maximum security. We don’t upsell product categories you don’t need.
- Permit pulling and scheduling. We handle the Miami-Dade Building Department permit. You don’t need to go to a permit counter or wait in line. Once the permit is issued, we schedule your installation date and confirm it with a reminder call – from a real person, not an automated text.
- Removal of the existing door and frame inspection. On installation day, we remove your old door carefully – protecting your flooring and interior trim. We inspect the rough opening, treat any moisture-compromised framing, and shim the new frame to plumb and level. In Miami’s sandy, shifting soil, out-of-plumb openings are common, especially in slab-on-grade homes in areas like Hialeah and Sweetwater. We account for that before the new door goes in, not after.
- Installation, flashing, and weathersealing. The new door is set, anchored to Miami-Dade code specifications, flashed at the head and sill, and sealed with an appropriate exterior-grade product. Every gap is closed. Every anchor point is set. This step is where a lot of cut-rate installers skip details – we don’t, because our 36500-Day Done Right Promise means we’re the ones coming back if it leaks.
- Final inspection and walkthrough. We schedule and pass the city or county inspection, then walk you through the finished installation – how to operate the hardware, what the warranty covers, and how to reach us if anything ever comes up. Upfront pricing means the number on your quote is the number on your invoice. No surprises.
Storm & Exterior Doors Pricing in Miami
Storm and exterior door installation in Miami typically runs between $900 and $4,500 installed, depending on door type, size, material, and frame condition. Here’s an honest breakdown of where costs land in this market:
| Door Type | Typical Installed Range (Miami) |
|---|---|
| Impact-rated fiberglass exterior door (single, standard 36″ x 80″) | $1,200 – $2,200 |
| Impact-rated steel exterior door (single, standard) | $900 – $1,600 |
| Therma-Tru fiberglass door with decorative glass insert | $1,800 – $3,200 |
| Double impact exterior doors (entry pair) | $2,400 – $4,500 |
| Storm door addition over existing exterior door | $400 – $900 |
| Frame rebuild or partial frame replacement (add-on) | $300 – $800 |
What Moves the Price Up or Down
- Frame condition. If the existing frame and sill are solid, installation is straightforward. Rot or water damage – common in Miami homes that have weathered multiple storm seasons – adds time and materials. We quote this honestly before we start, not as a surprise add-on mid-job.
- Door size and configuration. A standard 36-inch single door costs less than a wide 42-inch entry or a double-door configuration. Non-standard rough openings may require framing modification.
- Glass and hardware selections. An ES Windows impact door with a clear-lite sidelite costs more than a solid slab – and adds light and curb appeal. Hardware grade (lever sets, multi-point locks, smart-lock prep) also affects the total.
- Permit fees. Miami-Dade Building Department permit fees vary by job value. We include permit cost in our quotes so you see the real number from the start.
- Miami-Dade HVHZ requirements. Products must carry a Miami-Dade Notice of Acceptance. This sometimes means a price premium over non-HVHZ product lines, but it’s non-negotiable here – and it’s what your insurer and future buyer will look for.
All estimates are free, written, and itemized. If you have a written quote from another contractor, we’ll give you a free second opinion on it – no obligation. Seniors and veterans receive a permanent 10% discount on every job. And if your project qualifies as a repair over $200, we take $40 off automatically.

Why Miami Homeowners Choose Winslow
There’s no shortage of door installers advertising in Miami. What’s harder to find is one with a published address, a real owner’s name on the license, and a promise that doesn’t expire. Winslow Windows & Doors has operated in this market since 2011 – over 15 years of Miami-Dade installations, permit pulls, and post-storm callbacks. Ed Winslow built this business around a simple standard: every door we install should perform exactly as promised for as long as you own the home. The 36500-Day Done Right Promise puts that standard in writing. If something isn’t right, we make it right – full stop.
We’re an authorized installer for Therma-Tru and ES Windows, among others. That authorization matters because it means we’ve been vetted by the manufacturer, trained on their systems, and covered under their warranty programs. A door installed by an unauthorized contractor can void the product warranty before you’ve ever filed a claim.
Our technicians arrive in uniform, and you’ll know their name before the truck pulls up. We background-check every person on our crew because you’re letting us work on your home – and Ed takes that seriously.
Winslow Windows & Doors is part of our home service family, covering impact windows, doors, and roofing across South Florida. One company. One phone number. One promise.

FAQs – Storm & Exterior Doors in Miami
Do storm doors and impact exterior doors serve the same purpose in Miami?
Not exactly. An impact-rated exterior door is a primary Entry Doors product built to withstand hurricane-force wind and debris – it’s your main line of defense and is required to meet Miami-Dade’s NOA standards in the HVHZ. A storm door is typically a secondary, lighter-framed door installed in front of your primary door, adding an extra layer of weather protection and ventilation. In Miami, we usually prioritize upgrading the primary exterior door to a true impact product first. A storm door addition makes sense if your primary door is already impact-rated and you want additional airflow control or protection from wind-driven rain at an entry that faces south or east. Call us at (863) 946-5039 and we’ll tell you which option fits your specific entry.
How much does impact exterior door installation cost in Miami?
Most single impact exterior door installations in Miami fall between $900 and $2,200 installed, depending on material (steel versus fiberglass), size, glass configuration, and whether the frame needs any repair work. A Therma-Tru fiberglass door with a decorative glass insert typically runs $1,800 to $3,200. French & Double Doors can reach $4,500. Frame rot – which we see regularly in Miami homes that have taken on water over the years – adds to the total, and we’ll quote that in writing before work begins. Call (863) 946-5039 for a free on-site estimate with no trip charge inside Miami-Dade County.
Can you install a storm or impact door the same day you give the estimate?
Same-day installation is possible for in-stock product sizes and when no permit is required for a straight swap of the same door dimensions. In most Miami cases, however, we pull a Miami-Dade Building Department permit before installation – which adds a few days of lead time but protects you at resale and after any insurance claim. We’ll be straightforward about the timeline at your estimate appointment. If it can be done same day, we’ll tell you. If a permit is the right call, we’ll explain why and move as fast as the county allows.
Will a new impact exterior door lower my homeowner’s insurance in Miami?
Likely yes. Miami-Dade insurers factor opening protection into premium calculations, and a Miami-Dade NOA-rated impact door can qualify your home for wind mitigation credits – sometimes meaningful ones. The exact savings depend on your insurer, your policy structure, and whether all your openings are protected or just some. We can provide the product documentation your insurer or inspector will need after installation. For the most accurate estimate of your savings, request a wind mitigation re-inspection after we complete the work. Call us at (863) 946-5039 and we can walk you through what documentation we provide.
