If you’re finally pulling the trigger on hurricane protection for your South Florida home, one of the first questions you’ll ask is simple: how long does impact window installation take? It’s a fair question. You’re inviting a crew into your home, you’re investing thousands of dollars, and you want to know how long your life will be disrupted before you can enjoy the peace of mind (and lower insurance premiums) that come with impact-rated openings.
The honest answer is that it depends on more than most homeowners realize. A single-room replacement in Hollywood might wrap up in a day. A whole-house project in Coral Gables with twenty custom openings, arched transoms, and a tile-stucco exterior could stretch across two weeks once you count permitting, inspection, and any required exterior repairs. The actual installation labor is usually the shortest part of the timeline.
At A Plus Impact Windows & Doors, we’ve installed thousands of ES Windows units across Broward and Miami-Dade, and we’ve learned that setting realistic expectations up front prevents 90% of homeowner frustration. Below is a complete breakdown of what really drives the impact window installation timeline, what happens day by day on site, and how you can prepare to keep your project moving.
The Full Impact Window Installation Timeline, Start to Finish
When homeowners ask how many days to install impact windows, they’re usually thinking about the days a crew is physically on site. But the complete project timeline includes everything from the initial measure to the final county inspection. Here’s the realistic breakdown for a typical South Florida project:
| Phase | Typical Duration | What’s Happening |
|---|---|---|
| Estimate & contract | 1 to 3 days | Site visit, measurements, proposal, contract signing |
| Final field measure | 1 day | Precise measurements taken after deposit |
| Manufacturing (ES Windows) | 4 to 8 weeks | Custom fabrication at Medley, FL facility |
| Permit application & approval | 2 to 6 weeks | Submitted to Broward or Miami-Dade municipality |
| Installation | 1 to 10 days | Actual on-site work |
| Final inspection | 1 to 3 weeks after install | Municipal inspector verifies code compliance |
From signed contract to closed permit, most projects run 8 to 14 weeks total. The good news: choosing a locally manufactured brand like ES Windows shaves significant time off the manufacturing phase compared to national brands shipped in from out of state, which can take 10 to 16 weeks.
Single-Room vs. Whole-House Installation Timelines
The on-site labor portion of the impact window installation timeline scales roughly with the number of openings, but not in a perfectly linear way. Setup, cleanup, and inspection prep have fixed overhead regardless of project size.
Single Room or Small Project (2 to 5 windows)
A two-person crew can typically remove and install 4 to 6 standard-sized impact windows in a single day. If you’re replacing the windows in a master bedroom or a small condo unit, expect the actual installation to wrap up in one full workday, with a second short visit for stucco patching or interior trim touch-ups if needed.
Average Single-Family Home (10 to 15 openings)
This is the most common project we handle in Broward and Miami-Dade. A typical 3-bedroom, 2-bath home with 10 to 15 windows and one or two impact sliding glass doors will take 3 to 5 working days on site. Day one is usually demolition and rough opening prep, days two through four handle installation, and the final day covers caulking, interior trim, and cleanup.
Larger Homes (20+ openings)
Custom homes, two-story properties, and houses with French doors, arched windows, or wraparound sliders push the impact window replacement time to 7 to 10 working days. Larger crews can compress this, but in the HVHZ we prefer slightly smaller crews focused on quality, since every opening must pass inspection.
Whole-House Replacement with Exterior Work
If your project includes new entry doors, stucco re-coating, or replacement of damaged framing discovered during demo, add 2 to 5 days. Discovering rotted wood buck around an old aluminum window is common in homes built before 1995, and proper remediation is non-negotiable for both code compliance and warranty.
What Actually Affects How Long Installation Takes
Two homes with the same number of windows can have wildly different installation timelines. Here are the factors that genuinely move the needle:
Number and Size of Openings
Obvious, but worth stating: a 24-square-foot picture window takes longer to install than a 12-square-foot single-hung. Large fixed units from the ES Windows Series 400 line often require four installers to safely set, while a Series 100 single-hung can be handled by two.
Accessibility and Floor Level
Second-story windows require scaffolding or boom lifts. A two-story home in Weston with limited side-yard access can add a full day just for equipment setup. Condos above the 3rd floor often need swing-stage rigging coordinated with building management, which is a separate timeline conversation entirely.
Existing Window Type Being Removed
Old single-hung aluminum windows in a wood-frame opening come out fast. Original 1970s jalousie windows set in poured concrete with rusted steel anchors? That’s slow, dusty work. Steel casement windows from older Miami Beach homes can double removal time.
Custom Sizes and Shapes
Standard rectangular openings install fastest. Arches, octagons, trapezoids, and oversized units require more precise shimming and fastening. ES Windows fabricates custom shapes with full Miami-Dade NOA approval, but expect each custom opening to take roughly 1.5x the labor of a standard unit.
Exterior Wall Construction
Concrete block (CBS) construction, which dominates South Florida, is predictable and fast for fastening. Wood-frame homes in older Fort Lauderdale neighborhoods require more careful flashing and waterproofing. Stucco-over-foam exterior systems demand extra care to maintain the weather barrier.
Permit and Inspection Scheduling
This is outside the contractor’s full control. Some Miami-Dade municipalities turn permits around in 10 business days; others take 4 to 6 weeks. Broward cities like Hollywood and Pembroke Pines are generally faster than unincorporated areas. Inspectors typically arrive within 5 to 10 business days of a request.
What Happens During Installation, Day by Day
Understanding what happens on each day helps you plan around the work. Here’s a typical sequence for a 12-window single-family home installation:
Day 1: Protection, Removal, and Prep
The crew arrives between 7:30 and 8:00 AM, lays down floor protection, and covers furniture near work areas. Existing windows are removed one at a time, never all at once, so your home is never fully exposed. Old fasteners are extracted, rough openings are inspected, and any damaged bucks are repaired. Expect 4 to 6 openings to reach the rough-opening-ready stage on day one.
Days 2 to 3: Installation
New ES Windows units are dry-fit, shimmed plumb and level, and fastened per the product’s Notice of Acceptance fastening schedule. This is critical: NOA documents specify exact fastener type, length, spacing, and edge distance. Any deviation voids the HVHZ approval. Each unit is then sealed with approved sealants and the perimeter is flashed where applicable.
Day 4: Interior and Exterior Finishing
Stucco patching on the exterior, interior caulking, drywall touch-ups, and trim reinstallation. The crew walks the home with you, operates every window and lock, and reviews care instructions. All debris is hauled off.
After Installation: Inspection
We schedule the municipal inspection. The inspector verifies fastener compliance, NOA documentation, and proper sealant application. Once passed, the permit closes, and you receive documentation to submit to your homeowners insurance carrier using the OIR-B1-1802 mitigation form for premium discounts.
How to Prepare Your Home for Installation
A prepared homeowner can genuinely shorten the on-site timeline by half a day or more. Here’s what to do before the crew arrives:
- Remove window treatments, blinds, curtains, and rods from every opening
- Move furniture at least 4 feet away from interior window walls
- Take down wall art and shelves on adjacent walls (vibration from removal can knock items loose)
- Clear exterior plantings and outdoor furniture from beneath windows
- Secure pets in a separate room or arrange off-site care
- Disable security system sensors on the windows being replaced
- Plan to be home (or have someone home) for the first morning to review the work order
- Confirm parking arrangements for the crew’s truck and trailer
One more tip: if you have a strong preference for which rooms get done first (say, your home office or nursery), tell the project manager during the pre-installation walkthrough. Sequencing is usually flexible.
Why ES Windows Helps Compress the Timeline
One of the practical advantages of installing ES Windows in South Florida projects is that the manufacturer is based in Medley, FL, just minutes from most of our job sites. Shorter shipping distances mean shorter lead times, easier handling of warranty claims, and faster replacement of any unit damaged in transit. National brands shipped from Texas, North Carolina, or Wisconsin can add 4 to 6 weeks to your overall timeline before installation can even begin.
ES Windows also carries current Miami-Dade NOA approvals across its full residential line, Series 100 through Series 500, plus impact sliding glass doors and entry systems. That means our crews work from familiar, well-documented installation instructions, which speeds the actual on-site work and reduces the chance of inspection surprises.
Frequently Asked Questions
Can impact windows be installed in one day?
Yes, if the project is small. A 3 to 5 window replacement in a single room or small condo can typically be completed in one full workday, including removal, installation, and basic cleanup. Stucco or trim repair may require a brief return visit.
How many days to install impact windows in a typical 3-bedroom Florida home?
Most 3-bedroom, 2-bath South Florida homes with 10 to 15 openings take 3 to 5 working days for the actual on-site installation. The full project including permitting and final inspection usually spans 8 to 12 weeks from contract signing.
Do I need to move out during impact window installation?
No. Crews remove and install one opening at a time, so your home is never fully exposed. Most homeowners stay in their homes throughout the project. You may want to plan around dust and noise during demolition days, especially if you work from home.
What’s the longest part of the impact window replacement time?What’s the longest part of the impact window replacement time?
Manufacturing lead time, typically 4 to 8 weeks for ES Windows custom orders, and permit processing, which varies by municipality. The actual installation labor is usually the shortest phase of the entire project.
Will rain delay my installation?
Light rain usually doesn’t stop work, since crews can continue interior tasks. Heavy rain or lightning will pause exterior work for safety. South Florida’s afternoon summer storms are factored into our scheduling, which is one reason we start early in the morning.
How long after installation until I can claim my insurance discount?
Once the final inspection passes and the permit closes, you can submit the OIR-B1-1802 wind mitigation form to your insurance carrier. Most homeowners see premium reductions on their next renewal cycle, with some carriers issuing prorated refunds immediately.
Can you install impact windows during hurricane season?
Absolutely, and many homeowners do. Hurricane season runs June through November, and we install year-round. The only consideration is that if a named storm approaches and your project is mid-installation, we’ll prioritize getting all openings secured before the storm arrives.
