Fast, Reliable Door Replacement Across South Miami
Door replacement in South Miami runs $800 to $5,000 per opening for most homes, with whole-home packages landing between $8,000 and $25,000. What you actually pay depends on whether the door is impact-rated, the frame material, the size of the opening, and what we find inside the wall once the old jamb comes out. We schedule and coordinate our crews out of our Miami (South FL) office, so someone from Juniper Windows & Doors can usually be at your South Miami property within a couple of days to measure and scope the job. Call (682) 281-2168 and we’ll walk you through exactly what your specific door needs.
South Miami is not like the rest of the country when it comes to doors. We’re in the High-Velocity Hurricane Zone. Every exterior door has to carry a Miami-Dade County NOA or Florida Product Approval with a design pressure rating that matches the opening. A big-box door without those numbers won’t pass permit review, won’t survive a wind event, and won’t earn you a single dollar of wind mitigation credit. We handle that paperwork side for you, but it’s the first thing every South Miami homeowner should know before spending a dime.
Why Juniper Windows & Doors Is South Miami’s Preferred Door Replacement Company
We’ve been at this since 2001 under the Relay Home Co. family, and the thing South Miami homeowners tell us they appreciate most is that we don’t treat a door job like a mystery. You get a written price before any work starts. You get a live arrival time you can actually track. You get before-and-after photos of the opening. That’s the Relay Visibility Guarantee, and it applies to every job we do in South Miami, from a simple interior slab swap near Sunset Drive to a full impact-rated entry rebuild off Ludlum Road.
Our techs are background-checked, uniformed, and they show up with the right product approvals in hand for South Miami’s wind zone. If they need to pull the permit package together, they know what Miami-Dade County requires for door size, glass type, and design pressure. That’s not something a national handyman service thinks about. It’s something we think about every day.
And if anything isn’t right after the install, the 365-Day Done Right Promise covers it in writing. Parts and labor, for a full year. Sean Mackey, the owner, stands behind that promise personally.
Door Frame Repair in South Miami
Door frame repair in South Miami is one of those jobs that sounds small until you see what’s actually inside a 30-year-old jamb. In this climate, rain driven by summer afternoon storms finds every crack around an exterior door. Salt air from Biscayne Bay works on exposed wood and hardware. We regularly pull a door in neighborhoods around Dante Fascell Park and find the header or king stud soft enough to push a screwdriver through by hand. That’s why we inspect the rough opening before quoting anything.
Typical frame repair in South Miami runs $250 to $900 per opening when limited to jamb replacement and resealing. If the header has rotted or the rough opening needs shimming and reinforcement for an impact unit, the job lands closer to $900 to $1,500. The price gets written down before we cut into anything.
Jamb and Header Rebuilds
When the frame is too far gone, we replace the side jambs and header in pressure-treated or composite material that handles South Miami humidity better than old pine. We then seal the rough opening with flashing tape and a pan at the sill so storm water drains away from the framing instead of into it.
Hardware Corrosion Repair
Salt-laden air near the coast eats hinges, strike plates, and door bottoms faster than the finish warranty suggests. We replace corroded hardware with stainless steel or coated fasteners and adjust the slab so it seats properly against new weather stripping.
Interior Door Replacement in South Miami
Interior door replacement in South Miami is the inverse of the exterior job. There’s no permit, no product approval, no wind rating to worry about. It’s a cosmetic and functional upgrade, and it usually happens when a homeowner is already refreshing a bedroom, bath, or hallway. You’d be surprised how many South Miami ranch homes and 1950s concrete-block houses still have hollow-core doors that have warped from years of air-conditioned interiors and humid outside air.
Interior slab replacement in South Miami typically runs $150 to $400 per door for a standard hollow-core unit, and $400 to $900 for solid-core or pre-finished door systems with new casing. That includes removal, hardware transfer or replacement, and cleanup.
Solid-Core Upgrades
If noise between rooms is an issue, swapping hollow-core to solid-core changes the feel and the sound of the house immediately. South Miami homes with older floor plans often have bedrooms right off the living space; a solid-core door is the single biggest improvement you can make for under $1,000 a room.
Pre-Hung Replacements
When the frame itself is out of square or damaged, we install pre-hung units with the slab already set in the jamb. It’s faster than hanging a slab alone and the result is cleaner. We see this most often in older South Miami homes where door openings have shifted over decades.
Trusted Brands We Service in South Miami
We source doors from PGT, CGI, Therma-Tru, and a handful of other product lines we trust. For South Miami’s wind zone, PGT and CGI impact-rated doors are the most common calls. Therma-Tru fiberglass entries are a smart pick for homeowners who want the look of wood without the rot that comes with South Miami’s humidity and summer rain. Because we work with these manufacturers directly, we can pull spec sheets and NOA approval documents fast when a permit submittal needs them. We don’t stock generic slab doors that can’t be legally permitted here.
Common Door Replacement Problems We See in South Miami Homes
- Permit submittal stalls. The package is missing a product approval number and design pressure for that specific door size and configuration. Miami-Dade County doesn’t issue fix-it grants for paperwork; they just reject the submittal and delay the job. We handle this before it ever reaches review.
- Non-impact doors disguised as money savers. A homeowner swaps an exterior door for a non-impact unit with single-pane glass to save a few hundred dollars. Then the wind mitigation inspection fails and the insurance credit never comes. In South Miami, that “savings” costs more than the impact door would have.
- Hidden header and jamb rot. The slab looks fine from the street, but the frame is thirty years old and wicking moisture behind the stucco. We hang the new door and within a season it starts to rack because the rough opening was compromised. We inspect the frame on every exterior quote, whether you ask or not.
- Salt-corrosion hardware failure. Locks, hinges, and door bottoms on homes within a mile or two of the coast corrode faster than inland. South Miami sits close enough to Biscayne Bay that we spec stainless or coated hardware on any exterior door replacement, not brass finishes that will pit in two summers.
Pricing for Door Replacement in South Miami, FL
Here’s what we tell South Miami homeowners before we ever send a truck. Exterior impact-rated doors run $2,500 to $5,000 per opening for standard sizes. Non-impact exterior doors, where code allows them, run $800 to $1,800. Interior doors are the cheapest at $150 to $900 depending on slab and hardware. Frame repair adds $250 to $1,500 depending on the damage. What moves the price: opening width and height (non-standard sizes push fabrication costs in the HVHZ), glass package (laminated interlayer glazing is required for large-missile impact), frame material (fiberglass vs. wood vs. steel), and what we find when the old frame comes out.

What Door Replacement Costs in South Miami
The numbers above are honest anchors. But door replacement in South Miami often isn’t just a door. It’s the opening, the rough framing, the glass package, and the paperwork. Impact windows for comparison land around $800 to $1,500 per installed unit; impact single-hung windows $900 to $1,800; large or custom openings $2,500 to $5,000; whole-home packages combining windows and doors from $8,000 to $25,000 or more depending on opening count and wind zone.
South Miami’s High-Velocity Hurricane Zone means design pressures are matched to the specific opening, never a generic rating. The larger the door, the higher the required PSF rating, never above +/-100. Laminated glass interlayer glazing drives cost more than tempered. Fiberglass frames cost more than steel but won’t rust in coastal air. All of this gets scoped at the free measure. You get the written price, the product approvals, and the permit checklist before any work begins.
Florida Pays You Back
South Miami homeowners get real money back on impact-rated doors. The incentives stack. My Safe Florida Home matching grants run up to $10,000 for qualifying wind-mitigation upgrades, and a new impact-rated exterior door with the correct NOA is exactly the kind of improvement that qualifies. Florida’s sales-tax exemption applies to impact-resistant windows and doors, so you don’t pay state sales tax on the units. The federal 25C energy credit can return 30% of product cost up to $600 per year on qualifying ENERGY STAR units. And after a wind mitigation inspection ($75 to $150), your windstorm premium credit averages around 25% of the windstorm portion. No one can guarantee what your carrier will approve, but the inspection itself is the first step. We’ll point you to the right documentation.
We don’t install hurricane shutters. We install permanent impact-rated windows and doors. The advantage over shutters is simple: there are no panels to store, haul, and hang before a storm. The protection is always in place, and it qualifies for the same wind mitigation credits during your inspection.

FAQs About Door Replacement in South Miami
Yes, any exterior door replacement in South Miami requires a permit, and the door must carry a Miami-Dade County NOA or Florida Product Approval with a design pressure that meets or exceeds the opening’s required rating. We compile and submit the package (product approval, design pressure, installation method) so the review goes through without stalls. Call (682) 281-2168 for a quote that includes the permit scope.
No, not on any exterior opening in South Miami’s High-Velocity Hurricane Zone. Non-impact exterior doors don’t meet HVHZ impact requirements for wind-borne debris, fail permit review, and disqualify the opening from wind mitigation credits. Replacing with a compliant impact-rated door is the only path that keeps your insurance credits intact. We’ll show you the exact NOA for each door we recommend.
We source PGT, CGI, and Therma-Tru for most South Miami projects. PGT and CGI dominate impact-rated doors; Therma-Tru fiberglass entries handle the humidity and rain without warping. Glass packages are specified per opening to hit the design pressure rating the permit requires.
Once your units arrive, installation is as fast as a single day for most openings, and custom fabrication typically runs 4 to 6 weeks before that. The timeline from order to final inspection depends heavily on the fabrication queue for impact-rated doors in the HVHZ. We scope all of this at the free measure, including the inspection calendar.
Cost only changes when the scope changes. If we open the wall and find rotten framing, or the opening needs reframing to accept a proper impact unit, that’s a written change order before any additional work begins. You’ll never get a surprise invoice after the fact. The 365-Day Done Right Promise backs it all in writing.
