Window Replacement in Ojus, FL: What It Costs and How Long It Takes
Window replacement in Ojus typically runs $4,500-$15,000 for a full-home project and takes 2-5 days from tear-out to final inspection, depending on how many openings need updating and whether your existing frames can be reused. Most Ojus homes we work on need the full package: removal of original single-pane aluminum or jalousie windows, installation of HVHZ-compliant impact-rated units, and county sign-off. Call (844) 665-0162 and we’ll walk your property, measure every opening, and deliver a written estimate with product options.
How We Replace Windows in Ojus, Stage by Stage
We’ve refined this process across hundreds of Miami-Dade jobs. Here’s what actually happens, and what you’ll need to decide at each point.
Stage 1: Site survey and product selection (1-2 hours on-site, 3-5 days lead time for ordering)
We measure every rough opening to the eighth inch, check for settled or out-of-square frames, and photograph existing conditions. You’ll decide between retrofit installation (new window slides into the old frame) versus full-frame replacement (everything comes out, including sills and exterior trim). Retrofit costs less and disturbs less stucco, but full-frame is necessary when frames are corroded, termite-damaged, or too far out of plumb. You’ll also pick your product line from our Andersen, Pella, Marvin, or CGI catalogs, plus glass package and exterior color. We submit our measurements to the manufacturer; most custom units ship in 3-4 weeks.
Stage 2: Permit pull and HOA notification (3-10 business days, handled by our office)
Because Ojus is unincorporated Miami-Dade County, permits route through the county Building Department, not a city office. We file the window schedule, manufacturer NOA documentation, and HVHZ engineering data. If your home falls under an HOA in the Highland Lakes or Sans Souci Estates areas, we submit the product cut sheets and color samples for architectural review simultaneously. Homeowners sometimes wait weeks because they didn’t know their HOA needed pre-approval; we check this on day one.
Stage 3: Demo and prep (half day to full day)
Crews cover floors and furniture, remove interior trim carefully (we save what we can if it’s original hardwood), and cut out old windows. On 1950s-1970s concrete-block homes common in Ojus, we often find corroded aluminum frames fused to the masonry, failed sealant beds, and interior drywall damage from decades of condensation. We photograph everything unexpected and call before proceeding past the agreed scope.
Stage 4: Installation and weatherproofing (1-3 days)
New windows get set on sloped sills with back dams, shimmed to laser level, and fastened with HVHZ-approved concrete anchors into the block. We flash with self-adhered membrane, seal with backer rod and structural sealant, and reinstall or replace trim. Every opening gets a water-test before we move on. If you’re doing this as part of a full exterior update, our Windows & Doors in Ojus crew coordinates with roofing or siding phases so nothing gets sequenced backward.
Stage 5: County inspection and final walkthrough (scheduled next business day, 30 minutes on-site)
Miami-Dade sends an inspector to verify NOA labels, fastening patterns, and operability. We meet them with our permit card and photo log. Once green-tagged, we walk you through operation, cleaning, and warranty registration. Most manufacturers require online registration within 30 days to activate coverage.
The Window Options You’ll Actually Choose Between
- Vinyl frames (lowest maintenance, moderate cost): Cellular PVC construction won’t corrode in salt air, which matters in Ojus’s coastal climate. Thermal performance is solid, but color choices are limited and dark colors can soften in extreme heat. Best for homeowners who want reliability without premium pricing.
- Aluminum-clad wood (premium thermal performance, higher cost): Real wood interior you can stain or paint; extruded aluminum exterior withstands HVHZ wind loads without the heat-transfer penalty of solid aluminum. Requires periodic exterior sealant inspection. Suits historic-style homes where interior wood grain matters.
- Impact laminated glass (required in HVHZ, non-negotiable): Two panes bonded to a structural interlayer that holds together when shattered. All Ojus replacements must carry this. You’ll choose between clear, Low-E, or tinted coatings; Low-E with argon fill is standard for energy code compliance and blocks the infrared heat that bakes west-facing rooms.
- Single-hung versus casement versus horizontal roller: Single-hung is cheapest and most common for standard replacements. Casement seals tighter against wind (better for HVHZ) but costs more and projects outward, which can conflict with walkways or hedges. Horizontal rollers work well for wide, short openings typical of 1960s ranch layouts.
- Retrofit versus full-frame installation: Retrofit preserves exterior stucco and interior trim, cutting cost 15-25%. Full-frame reveals hidden damage, allows insulation upgrades, and lets us correct out-of-square openings, but adds $150-$400 per opening and extends timeline by a day.
What Window Replacement Costs in Ojus, FL
Most full-home window replacement projects in Ojus fall between $4,500 and $15,000. Here’s what pushes you toward either end:
| Cost Driver | Low-End Scenario | High-End Scenario |
|---|---|---|
| Window count and size | 8-10 standard single-hung openings | 15+ openings including picture windows and sliders |
| Frame condition | Existing aluminum frames clean and square | Corroded frames, termite damage, or out-of-square block openings requiring full-frame replacement |
| Product grade | Vinyl impact-rated, builder grade | Architectural-grade aluminum-clad wood with custom divided lites |
| Interior trim | Retrofit preserves existing drywall returns | Custom wood extension jambs, new casing, and site-finished trim |

What Ojus Homes Specifically Do to This Job
Ojus sits in Miami-Dade County’s High-Velocity Hurricane Zone, and that changes everything about window replacement here. Every product we install must carry a Miami-Dade Notice of Acceptance - a county-specific certification stricter than Florida’s statewide approval. Contractors working from Broward County just up the road in Hallandale Beach or Fort Lauderdale sometimes bring materials that are perfectly legal there but non-compliant in Ojus. We’ve been called in to re-do jobs after inspectors red-tagged windows that lacked the right NOA numbers.
The housing stock compounds this. The concrete-block ranches along NE 186th Street and in the Sans Souci area were built from the 1950s through the 1970s with single-pane jalousie or early aluminum windows, flat roofs, and minimal insulation. Those original windows weren’t designed for impact resistance or modern energy codes. When we open the walls, we regularly find corroded frames embedded in the block, failed sealant that has been letting water migrate for decades, and interior drywall stained from condensation running down cold aluminum in summer.
Because Ojus is unincorporated, permits pull through the county Building Department rather than a city office. The inspection queue, fee schedule, and plan-review contacts are county-wide, and contractors unfamiliar with this system often mis-file or underpay. We know the specific Miami-Dade forms and the inspectors who cover this zone, which keeps timelines predictable.
Homeowners in Ojus often pair exterior envelope work with property-line upgrades. If you’re replacing windows and also rethinking your yard’s perimeter, we can coordinate Vinyl Fence in Ojus or Aluminum Fence in Ojus as part of the same project schedule, using one crew relationship instead of juggling separate contractors.

Frequently Asked - Window Replacement in Ojus
Most full-home window replacements take 2-5 days of active work, plus 3-4 weeks for custom window manufacturing and 3-10 business days for Miami-Dade permitting. Call (844) 665-0162 and we’ll give you a project-specific timeline after measuring your openings.
Yes. Any window replacement in unincorporated Miami-Dade County requires a building permit with HVHZ product documentation and a final inspection. We handle the entire permit process, including the Notice of Acceptance paperwork that out-of-area contractors often miss.
Often yes. Retrofit installation slides new windows into existing frames, preserving interior drywall returns and exterior stucco. This works when frames are structurally sound and reasonably square. If frames are corroded, out-of-plumb by more than a quarter inch, or embedded in damaged block, full-frame replacement becomes necessary.
For original single-pane aluminum or jalousie windows common in Ojus, replacement is almost always the better investment. Repairs can’t bring non-impact windows up to HVHZ compliance, and the energy savings from modern insulated glass typically recover 15-25% of project cost within five years. Call (844) 665-0162 and we’ll inspect your specific windows to confirm.
Manufacturer warranties vary by product line: most vinyl windows carry 20-year glass and lifetime frame coverage, while aluminum-clad wood often includes 10-20 years on exterior finish and 20 years on glass seal failure. Our installation workmanship is warrantied for the period we specify in your written contract. We register all warranties with the manufacturer on your behalf.
