Door Installation in Ojus, FL: Timeline, Cost, and What to Expect
Door installation in Ojus typically runs $450-$2,800 per opening depending on material grade, structural condition, and whether you’re replacing in-frame or reframing for a new size or location. Most standard replacements finish in a single day; jobs requiring new headers, impact-rated upgrades, or structural modifications for HVHZ compliance stretch to 2-3 days.

How We Handle Door Installation From First Measure to Final Walkthrough
We’ve refined our door installation process across hundreds of Ojus homes, mostly 1950s-1970s concrete-block ranches with original aluminum or hollow-core doors that no longer seal against wind-driven rain. Here’s what actually happens, and when you’ll need to make decisions.
Stage 1: Site measure and condition check (30-60 minutes, day of estimate)
We measure the rough opening, check the existing frame for rot or termite damage, and determine whether your wall is block with wood buck or full wood frame. In Ojus, we often find original frames set directly into Miami Limestone block with minimal flashing, which explains the moisture staining we see at sill plates. You’ll decide at this stage whether you’re keeping the same size or expanding the opening, and whether you want standard or impact-rated product. We photograph everything and note any electrical or plumbing runs near the opening.
Stage 2: Product selection and permit pull (3-10 business days)
Because Ojus sits in Miami-Dade County’s High-Velocity Hurricane Zone, every exterior door must carry a Miami-Dade Notice of Acceptance (NOA), not just Florida state approval. We spec your door from our curated brand partners - Andersen, Pella, Marvin, Milgard, Jeld-Wen, Simonton, PGT, or CGI - and confirm the NOA documentation before ordering. If you’re part of a full Windows & Doors in Ojus project, we batch permits to save time. For standalone door work, we file directly with Miami-Dade County’s Building Department since Ojus is unincorporated; contractors used to city offices in Aventura or Hallandale Beach often stumble here. You’ll approve the final spec, finish, and hardware package during this window.
Stage 3: Demo and rough opening prep (2-4 hours, day 1 of install)
We protect floors and adjacent walls, remove the old door and frame, and expose the rough opening. This is where we discover hidden issues: corroded fasteners, compromised wood bucks, or previous water intrusion into the block cavity. If we’re installing a wider door or sidelights, we install a new engineered header and temporary supports. For homes with the original 1950s-1970s construction we see throughout Ojus, we almost always find some degree of fastener corrosion from decades of salt air exposure.
Stage 4: Door hang, seal, and hardware set (3-6 hours)
We set the pre-hung unit or frame components, shim plumb and square, and anchor with stainless or coated fasteners rated for coastal exposure. Flashing tape goes on in shingle fashion, sill pan drains to exterior, and we foam-seal the gap between frame and rough opening. Hardware - locksets, hinges, sweeps - gets installed and adjusted. For impact-rated units, we verify the glazing and anchoring match the NOA exactly; inspectors in Miami-Dade check this.
Stage 5: Trim, paint touch-up, and inspection (1-2 hours, sometimes next day)
Interior and exterior trim goes on, caulked and painted to match. We clean the work area, test operation, and review the finished product with you. If permits were pulled, Miami-Dade schedules the inspection; we meet the inspector and address any punch items. Most of our Ojus door installations pass first time because we build to the NOA spec from the start.
The Door Choices That Actually Change How Your Installation Goes
Not all doors suit every Ojus opening. Here’s what we walk homeowners through, with the real trade-offs:
- Fiberglass entry doors: Best all-around for coastal Florida. Won’t rust, dent, or swell, and modern grain textures convincingly mimic wood. Mid-range cost, excellent insulation. The downside: premium fiberglass units with decorative glass can push toward $2,500+ installed. We often spec these for street-facing entries in Ojus ranches.
- Steel entry doors: Strongest security, lowest cost for a solid door. But in Ojus’s salt-air environment, uncoated steel edges and corners corrode within 3-5 years unless you stay vigilant with touch-up paint. We only recommend steel with factory-applied baked enamel or vinyl coating, and we warn owners about maintenance.
- Solid wood doors: Unmatched aesthetics for Craftsman or mid-century modern homes. Requires covered entry or substantial overhang in this climate; direct sun and rain will warp and delaminate veneer within a few seasons. We install these with extended jambs and premium seal systems, and we’re upfront about the maintenance commitment.
- Impact-rated vs. standard construction: HVHZ code requires impact-rated for most exterior doors in Ojus, but decorative glass inserts must also be impact-rated, which limits some style choices. Standard construction saves money but can’t pass permit for exterior exposure; we see it occasionally for interior garage or courtyard doors where code allows.
- Pre-hung vs. slab-only: Pre-hung simplifies installation and ensures frame-to-door fit, especially important for impact-rated assemblies where tolerance is tight. Slab-only makes sense when you’re preserving historic trim or matching existing frame conditions, but it adds labor and risk.
- Hardware grade: Coastal-grade stainless or bronze hinges and locksets resist corrosion far longer than builder-grade zinc or plated steel. For homes within a mile of the Intracoastal, we consider this non-negotiable.
What Door Installation Costs in Ojus, FL
Interior door replacement: $450-$1,200 per opening. Exterior standard replacement in existing frame: $900-$1,800. Exterior with reframing, header work, or impact-rated upgrade: $1,600-$2,800. French or double-door assemblies run $2,200-$4,500 depending on width and hardware complexity.
Five factors push your number up or down:
- Existing frame condition: Rot, termite damage, or corroded fasteners add $200-$600 for repair or replacement before the new door goes in. We see this in roughly half the Ojus homes built before 1980.
- Structural modifications: Widening an opening, adding sidelights, or converting a window to a door requires new headers, temporary supports, and often engineering. Add $800-$2,500.
- Material grade and brand: A basic fiberglass unit from Jeld-Wen or Simonton runs well under an architectural-grade Marvin or Pella with custom glass. The spread can be $1,000+ for the same opening size.
- Impact rating and HVHZ compliance: NOA-certified impact assemblies cost 30-50% more than standard construction, and the documentation burden adds administrative time. This is mandatory for most exterior work in Ojus, not optional.
- Finish carpentry and trim: Matching existing baseboard, casing profiles, or exterior siding adds material and labor. Paint-grade trim is economical; stain-grade hardwood or PVC for coastal durability costs more.
Our written estimates include the door unit, delivery, demolition of existing, rough opening prep, installation, standard trim, hardware, cleanup, and permit coordination. What typically isn’t included: structural engineering stamps, electrical relocation for relocated doors, custom paint or stain beyond primer, and decorative glass upgrades beyond standard options.
Why Ojus Homes Make Door Installation Different
Ojus presents a specific regulatory and physical environment that shapes every door installation we do here. The unincorporated status means permits route through Miami-Dade County’s Building Department, not a local city office. We’ve watched out-of-area contractors misfile permits, underpay fees, or schedule inspections through non-existent city channels, delaying projects by weeks. Our crew knows the county inspectors and the NOA documentation they expect.
The housing stock matters too. Those 1950s-1970s concrete-block ranches dominate the residential core, and many still carry original aluminum sliders or hollow-core entries. When a homeowner updates one door as part of a larger renovation, current HVHZ rules often trigger full envelope upgrades - impact-rated windows, reinforced garage doors, updated roof connections. We’ve had clients start with a single front door replacement and end up addressing the whole opening package because the inspector flagged adjacent non-compliant glazing. It’s not our preference to expand scope, but we’d rather warn you upfront than discover it mid-project.
The salt-air corrosion we mentioned isn’t theoretical. In the eastern sections of Ojus closer to the Intracoastal, we regularly remove hinges and fasteners that have degraded to structural concern. Our standard spec for this area includes stainless steel or hot-dip galvanized hardware, and we check the wood buck behind the frame for moisture intrusion from wind-driven rain. The shallow water table and porous Miami Limestone mean slab-on-grade homes here are prone to wicking moisture; we verify sill pan drainage and vapor barrier continuity as part of every exterior door install.
Homeowners often pair door work with exterior security or boundary improvements - we also install Chain Link Fence in Ojus and Vinyl Fence in Ojus for clients who want the full perimeter addressed by one accountable team.

Frequently Asked - Door Installation in Ojus
Most standard replacements finish in one day. Jobs requiring new framing, structural headers, or impact-rated upgrades for HVHZ compliance typically take 2-3 days, plus permit inspection scheduling. Call (844) 665-0162 and we’ll time out your specific opening.
Yes, for any exterior door replacement or modification, because Ojus falls under Miami-Dade County’s High-Velocity Hurricane Zone. The permit ensures your door assembly meets the Miami-Dade Notice of Acceptance required for wind and impact resistance. Interior door swaps in existing frames usually don’t require permitting. We handle all county filings as part of our service.
If you’re keeping the same door location and size, almost always yes. Problems arise when you want to widen the opening or relocate the door, which may intersect wall cavities containing electrical runs or, in rare cases, plumbing stacks. We map these with stud finders and exploratory cuts before committing to the layout change.
A standard steel pre-hung unit in good existing frame condition runs toward the lower end, around $900-$1,200 installed. But in Ojus’s HVHZ zone, you’ll still need impact-rated or pressure-rated product with proper NOA documentation, which sets a higher floor than non-coastal markets. We don’t recommend cutting corners on fasteners or flashing; the salt air will punish shortcuts within a few years.
Our workmanship warranty covers installation labor, flashing, and seal integrity. The door unit itself carries the manufacturer’s warranty - typically 10 years to lifetime on fiberglass and steel doors from our brand partners, with glass coverage varying by product line. We register warranties on your behalf and keep documentation on file. For warranty claims, you call us first; we coordinate with the manufacturer so you’re not chasing two parties.
