French & Double Doors in Miami, FL

Door Installation for French and double doors in Miami typically runs $1,800 to $6,500 installed, depending on door size, glass type, impact rating, and hardware. Most jobs are completed in a single day, and every door we install carries our 36500-Day Done Right Promise – if something’s not right, we come back and make it right, full stop.

At Winslow Windows & Doors, Ed Winslow has been personally overseeing door projects across Miami since 2011. When you call (863) 862-5435, a live person picks up – not a voicemail, not a call center. You get a real answer, a real estimate, and a crew that shows up in uniform with their identities verified before they ever set foot on your property.

French and double doors aren’t a small purchase, and in Miami they carry requirements that don’t apply in most of the country. Between the Miami-Dade County NOA (Notice of Acceptance) mandates, South Florida’s wind-load code requirements, and the everyday reality of salt air eating through inferior hardware, the Hurricane-Proof Front & Entry Doors you pick – and the company that installs them – matter more here than almost anywhere else. We’re an authorized installer for brands built specifically for this climate, including Therma-Tru and ES Windows, and we pull permits, handle inspections, and stand behind the work with a promise that outlasts any standard warranty.

If you’re exploring the full scope of what we do, our Door Installation in Miami page covers every door type we install across the county.

When You Need French & Double Doors

Not every homeowner is sure whether their situation calls for a simple repair or a full Replacement Doors project. Here are the scenarios we see most often across Miami neighborhoods like Coral Gables, Pinecrest, Coconut Grove, Brickell, and Doral:

• Your current entry or patio doors don’t meet Miami-Dade impact requirements. If your home was built before 2002 or if you purchased a property that was never properly upgraded, there’s a real chance your existing doors aren’t code-compliant for hurricane season. We see this constantly in older Coconut Grove bungalows and pre-code construction in Little Havana. Non-compliant doors can void your homeowner’s insurance and put your family at serious risk.
• You’re replacing a single entry door with a more open, grander entryway. Many Miami homeowners in Coral Gables and Pinecrest are converting single-door openings to full French door sets to match the architectural character of Mediterranean Revival and Spanish Colonial homes. This involves structural work at the rough opening – it’s not a swap, it’s a build.
• Salt air and humidity have corroded your existing hardware and warped your door frame. Miami’s proximity to Biscayne Bay and the Atlantic means salt-laden air gets into everything. We regularly replace French door sets in Coconut Grove and Key Biscayne where the original wood frames have swollen, the multi-point locks have seized, and the threshold has rotted through. At that point, repair isn’t the answer.
• You’re adding a rear entry from a living space to a pool deck or outdoor kitchen. Brickell condos and Doral single-family homes alike have been renovating hard toward indoor-outdoor living. A properly installed, impact-rated double door set opens a wall safely and legally – but it requires a permit and a Miami-Dade approved product.
• Your current French doors let in noise, heat, or drafts. If you’re feeling the afternoon heat press through glass panels or hearing Biscayne Boulevard like you’re standing on it, your doors have either failed their seals or were never energy-efficient to begin with. New thermally broken frames and Low-E impact glass resolve both problems at once.
• You’re preparing for a sale and the entry makes the wrong first impression. Realtors across Miami consistently report that the entry door is one of the first things buyers notice. A warped, faded, or undersized double door undercuts curb appeal in a market where first impressions move quickly.

Our French & Double Door Installation Process

We don’t wing it on the day of installation. Every French and double door project follows a defined process that protects your home, your investment, and our ability to stand behind the finished job.

1. On-site measurement and structural assessment. Before we recommend a single product, one of our team members comes to your home to measure the rough opening, inspect the surrounding framing and sill, and check for any moisture intrusion or rot that needs to be addressed before a new door goes in. In Miami’s climate, skipping this step is how a new door fails in three years. We don’t skip it.
2. Product selection and permitting. We’ll walk you through door options that are Miami-Dade approved and carry the required NOA for your specific wind zone. We install Therma-Tru fiberglass French door systems and ES Windows products, both of which are built to perform in South Florida conditions. Once you’ve selected your door, we handle the permit application with Miami-Dade Building Department. Upfront pricing means you see the full cost – labor, materials, permit fees – before we start.
3. Old door removal and opening preparation. On installation day, our uniformed, background-checked crew removes the existing door unit carefully to avoid damaging the surrounding drywall or stucco. We inspect the rough opening, treat any moisture or rot we find, and shim the frame to level and plumb. In Miami homes built on slab, this step often reveals issues the original builder skipped. We address them before the new door goes in.
4. Door installation and sealing. The new door unit is set, anchored per Miami-Dade fastening requirements, and flashed and sealed against South Florida’s driving rain. French door systems with sidelites require particular attention to the sill dam and perimeter seal – water infiltration on the threshold is the most common callback we see on work done by crews who rush this step. We don’t rush it.
5. Hardware installation and operation check. Multi-point locking systems, hinges, astragals, and door handles are installed and adjusted. We open and close the doors dozens of times to confirm smooth operation, proper latching, and deadbolt alignment. Impact-rated French doors are heavier than standard doors – the hardware has to be set precisely or the door will sag within a year.
6. Final inspection and walkthrough. We schedule the city or county inspection, and once it passes, we do a full walkthrough with you. We show you how to operate the multi-point lock, explain the warranty on both the product and our labor, and leave the job site cleaner than we found it. If anything isn’t right before we leave, we fix it before we leave. That’s the 36500-Day Done Right Promise in practice.

French & Double Door Pricing in Miami

French and double door installation in Miami costs more than in most U.S. cities, and the reason is straightforward: Miami-Dade impact requirements mean you’re buying a genuinely different product. The pricing below reflects installed cost – labor, door unit, hardware, permit, and standard opening prep. These are real ranges based on what we actually see in the Miami market.

What moves the price in Miami specifically

• Miami-Dade NOA compliance: Every door sold and installed in Miami-Dade County must carry a Notice of Acceptance for the applicable wind zone. NOA-compliant products cost more than equivalent non-impact doors – and they should. We don’t offer non-impact alternatives in this market.
• Frame material: Fiberglass (Therma-Tru) holds up better to Miami’s salt air and UV exposure than wood and costs less to maintain long-term. We typically recommend fiberglass for exterior applications in South Florida over wood for this reason.
• Glass configuration: Full-lite French doors with maximum glass area let in more light but cost more than half-lite or three-quarter-lite configurations. Low-E coatings add to the material cost but reduce your cooling load – which matters when the AC runs nine months of the year in Miami.
• Existing opening condition: Homes in Coral Gables and the Roads neighborhood often have original 1940s and 1950s framing that needs sistering or header replacement before a modern door unit can be installed properly. We find this on almost every job in those neighborhoods.
• Permit and inspection fees: Miami-Dade permit fees vary by project value. We include the permit in our upfront quote so there are no surprises on invoice day.

Seniors and veterans receive a permanent 10% discount on all work – no expiration, no paperwork beyond confirming eligibility.

FAQs – French & Double Doors in Miami

Do French doors need to be impact-rated in Miami?

Yes – any Storm & Exterior Doors installed in Miami-Dade County must comply with the High-Velocity Hurricane Zone (HVHZ) code and carry a Miami-Dade Notice of Acceptance. This applies to French doors, double doors, and any door with glass panels. A non-impact French door is not code-legal for exterior installation in this county, and it will fail a permit inspection. If a contractor offers you a standard (non-impact) French door for an exterior opening in Miami, that’s a serious red flag. Call us at (863) 862-5435 and we’ll walk you through the compliant options – free estimate, no trip charge within the home county.

How long does French door installation take in Miami?

Most French and double door installations take one full day – typically six to eight hours for a straightforward swap into an existing rough opening. If the opening needs to be modified or the framing requires repair (common in older Miami homes), plan for a day and a half to two days. Permit approval from Miami-Dade Building Department adds time before the installation date, usually one to two weeks depending on current volume at the department. We factor this into your project timeline at the estimate stage so nothing surprises you mid-project.

What’s the difference between French doors and double doors?

Double doors are simply two door panels that meet in the middle – they can be solid, partially glazed, or fully glazed. French doors are a specific style of double door characterized by full-length glass panels divided by muntins (the thin strips that separate individual panes). In practical Miami terms, both styles can be impact-rated, both require the same permitting, and the main decision comes down to how much natural light you want and how the door fits the architecture of your home. Therma-Tru makes both styles in configurations approved for South Florida’s wind zone, and we can show you samples at the estimate.

Can you replace a single door with French doors without major construction?

It depends on the current rough opening size and what’s in the wall. A standard single-door rough opening (typically 38 to 42 inches) is too narrow for most French door sets, which start around 60 inches wide. Widening the opening means cutting into the wall, installing a new structural header, and possibly relocating electrical. We see this in a lot of Doral and Kendall homes where the original builder put a single entry on a wall that could architecturally support a double door. It’s absolutely doable and we handle it regularly – but we need to assess the wall before we can quote it accurately. The on-site estimate is free. Call (863) 862-5435 to schedule one.
