Door Installation in North Miami: What It Costs and How Long It Takes
Door installation in North Miami typically runs $450 to $2,800 per unit depending on material grade, framing condition, and whether hurricane-impact rating is required. Most residential replacements take one to two days; new openings or structural modifications add two to four days for framing and Miami-Dade permit inspection.

How We Handle Door Installation from Start to Finish
We’ve learned that door installation in North Miami goes smoother when homeowners know exactly what happens and when they need to make decisions. Here’s how we stage every job.
Stage 1: Site measure and spec lock (Day 1, 1-2 hours)
We measure the rough opening, check plumb and level of existing framing, and photograph the surrounding wall construction. On North Miami’s 1950s-1970s CBS ranch homes, we often find original wood buck frames embedded in single-wythe block that have rotted at the sill or pulled away from the slab. You decide on door swing, hardware finish, and whether you want a multi-point locking system at this stage. We bring sample boards for stain or paint-grade options.
Stage 2: Permit pull and material order (2-5 business days)
For like-for-like replacement in the same opening, Miami-Dade often allows a minor repair permit with same-day issuance. Any new opening, structural modification, or impact-rated upgrade triggers a full building permit with plan review. We handle the application, the wind-load documentation, and the scheduled inspections. Material lead times vary: standard fiberglass or steel units ship in 5-10 days; custom impact-rated wood or aluminum-clad units run 4-8 weeks.
Stage 3: Demo and rough prep (Day 1 of install, 2-4 hours)
We protect floors and adjacent trim, remove the old unit, and expose the rough opening. On older CBS construction, this is where we discover the surprises: corroded steel lintels above the opening, termite-damaged wood bucks, or block that crumbles when we cut for anchors. If we find it, we stop, photograph, and call you with the repair scope before proceeding. No hidden work gets done without a change order you approve.
Stage 4: Install and seal (Day 1-2, 4-6 hours)
We set the new frame on a bed of polyurethane sealant, shim to plumb, and anchor through the frame into solid block or wood buck with stainless steel fasteners rated for coastal exposure. We flash the head and jambs with self-adhered membrane, install the door slab, hang hardware, and test operation. Impact-rated units get a separate inspection for missile-impact certification labels. We caulk interior and exterior perimeters with paintable silicone.
Stage 5: Trim, finish, and final inspection (Day 2-3, 2-3 hours)
Interior casing goes in, exterior brickmold or trim gets fitted, and we touch up paint or stain where needed. If Miami-Dade requires a final inspection, we coordinate the inspector’s visit and don’t consider the job closed until it passes. You do a walk-through with our lead carpenter, and we leave you with the manufacturer’s warranty card and our workmanship guarantee.
The Door Options You’ll Actually Choose Between
Every door installation in North Miami forces a decision tree. Here’s where the money goes and what you give up or gain with each path.
- Steel slab ($450-$900 installed): The practical choice for rear utility doors and garage-access entries. Galvanized skins resist dents better than aluminum, but the factory finish scratches and will rust if breached. Energy performance is middling; the core is usually polystyrene. Best for covered entries where curb appeal matters less.
- Fiberglass skin with composite frame ($700-$1,400 installed): The sweet spot for most North Miami front door replacements. The skin can be grained and stained to mimic mahogany or oak without the maintenance. Composite frames don’t absorb moisture like wood, critical in a climate with 60+ inches of annual rainfall and salt air. We spec these with polyurethane cores for R-values around R-5 to R-6.
- Impact-rated fiberglass or aluminum ($1,200-$2,800 installed): Required by code for any new opening or substantial improvement in Miami-Dade HVHZ. These carry AAMA 506 and Miami-Dade NOA certifications for large-missile impact and cyclic pressure. The laminated glass and reinforced frames add weight, so we upgrade hinges and specify multi-point locks. This is non-negotiable if your project triggers the 50% rule or if you’re in a designated flood zone requiring elevation compliance.
- Solid wood or wood-clad ($1,500-$3,500+ installed): Mahogany, sapele, or teak for architectural-grade entries. Stunning, heavy, and demanding. Annual refinishing is realistic in South Florida sun and rain. We only recommend these for deeply covered porches where direct exposure is minimal, or for homeowners committed to the maintenance cycle.
- Hardware grade: Builder-grade brass or nickel handlesets run $80-$200; multi-point locking systems with concealed bolts add $300-$600 but are required for impact-rated units and strongly advised for any door over 36 inches wide. Smart lock prep adds $50-$150 to the door slab machining.
What Door Installation Costs in North Miami, FL
For standard residential door installation in North Miami, expect $450 on the low end for a basic steel replacement in good existing framing, and $2,800 or more for a custom impact-rated unit with sidelights in a new opening requiring structural modification.
| Scope | Typical Range |
|---|---|
| Like-for-like replacement, steel or fiberglass, good frame | $450-$1,100 |
| Replacement with impact-rated upgrade, existing opening | $1,200-$1,900 |
| New opening in CBS wall, standard door | $1,800-$2,800 |
| New opening with impact rating, structural header, trim | $2,500-$4,500 |
Five variables push you to the high or low end of these ranges:
Existing frame condition. Rotted wood bucks in old CBS construction add $300-$800 for pressure-treated replacement and proper flashing integration.
Impact rating requirement. If your project triggers HVHZ compliance, the door unit itself costs 40-60% more, and the permit/inspection cycle adds $200-$400 in fees and labor.
Structural modification. Cutting a new opening in a load-bearing block wall requires a engineered lintel, temporary support, and structural inspection. This is the biggest cost driver beyond the door itself.
Material grade and glass. Decorative glass inserts, sidelights, or transoms multiply the unit cost. Low-E laminated impact glass runs $400-$900 per sidelight.
Finish carpentry and trim. Matching existing interior casing or exterior stucco returns takes time and skill. We price this per linear foot based on complexity.
Our written estimates include the door unit, freight, permit fees, labor, rough and finish materials, and debris haul-off. What they don’t include: interior painting or staining (we’ll prime exterior frames), landscape repair if access is tight, or any asbestos or lead-paint remediation if pre-1978 surfaces test positive.
Why North Miami’s Older Homes Change Every Door Job
Door installation in North Miami isn’t plug-and-play. The city’s housing stock, built overwhelmingly between 1950 and 1975, predates every modern building standard that now governs renovation work here.
Those original CBS ranch homes along NE 135th Street and the neighborhoods branching off Biscayne Boulevard were built with single-wythe block walls, flat roofs, and wood buck frames set directly into the masonry. None of it was designed for the wind loads Miami-Dade now enforces. When we quote a door replacement on one of these properties, we’re pricing in the probability that Miami-Dade inspectors will flag the existing structure during permit review.
The 50% rule is the shadow over every project. If your renovation’s assessed value exceeds 50% of the structure’s market value, you’re no longer doing a repair; you’re doing a substantial improvement. That triggers full compliance with current FEMA Base Flood Elevation requirements and HVHZ impact standards for the entire structure, not just the new door. We’ve seen homeowners in the 33161 ZIP code start with a $1,200 door replacement and end up facing $15,000+ in whole-house hardening because the inspector found non-impact windows and missing hurricane straps during the same permit cycle.
Experienced contractors in North Miami price this risk from the first conversation. We inspect the roof-to-wall connection, check for existing impact ratings on nearby openings, and flag whether your project sits in an AE flood zone where elevation compliance may apply. It’s not pessimism; it’s protecting you from a mid-project scope explosion.
The salt air and saturated soil don’t help either. North Miami’s position between Biscayne Bay and the Everglades drainage means high humidity year-round and a water table that keeps slab-adjacent wood in perpetual moisture stress. We spec stainless or ceramic-coated fasteners, use closed-cell backer rod with polyurethane sealants, and never install wood sills directly on concrete without a composite or PVC break.
Homeowners doing exterior work often coordinate door installation with other envelope improvements. If you’re already opening walls, pairing this with Windows & Doors in North Miami as a full-scope project can reduce mobilization costs and ensure consistent trim, flashing, and impact ratings across all openings. Our Windows & Doors crew handles both trades under the same permit and inspection sequence. Some clients also bundle exterior work with Chain Link Fence in North Miami or Vinyl Fence in North Miami to complete the property perimeter in one build phase.

Frequently Asked - Door Installation in North Miami
Most replacements finish in one day; new openings or impact-rated upgrades take two to three days plus permit inspection scheduling. Call (844) 665-0162 and we’ll give you a firm timeline based on your specific opening and whether Miami-Dade requires a full permit review.
Yes, nearly always. Like-for-like replacement in the same opening may qualify for a minor repair permit, but any new opening, structural modification, or impact-rated upgrade requires a full Miami-Dade building permit with wind-load documentation. We pull permits as part of every job and coordinate inspections.
If you’re using the existing rough opening, yes. Plumbing and electrical only become factors when you’re relocating the door to a new wall location or widening the opening into a space with adjacent utilities. We locate utilities before cutting and will tell you during the estimate if relocation is likely.
A fiberglass slab in a composite frame, non-impact, in good existing framing, typically runs $700-$1,100 installed. It outlasts steel in salt air and needs less maintenance than wood. If your project triggers HVHZ compliance, impact-rated fiberglass starts around $1,200. Call (844) 665-0162 for an exact quote - estimates are free.
The manufacturer’s warranty covers the door slab and frame, typically 10 years to lifetime depending on brand and material. Our workmanship warranty covers installation labor, flashing, and sealant integrity. We register your warranty and leave you with all documentation at final walkthrough.
