How Long Does Impact Window Installation Take?
A practical guide to impact window installation timelines in South Florida. From permits to final inspection, know exactly what to expect.
Understanding the impact window installation timeline helps you plan your project without surprises. Here's what to expect from the moment you request a quote to the final building inspection.
The Complete Timeline
Phase 1: Consultation & Quote (1-2 days)
A certified estimator visits your home to measure every window and door opening. You'll receive a detailed quote within 24-48 hours with product recommendations based on your budget and design preferences.
Phase 2: Permitting (1-3 weeks)
In Miami-Dade, Broward, and Palm Beach counties, a building permit is required for impact window installation. The timeline depends on your municipality:
- Miami-Dade County: 5-10 business days
- Broward County: 3-7 business days
- Palm Beach County: 5-15 business days
At Izoah, we handle 100% of the permitting process so you don't have to visit any government offices.
Phase 3: Manufacturing (4-8 weeks)
Once your permit is approved, we place the order with the manufacturer. Most impact windows are custom-built to your exact specifications. This is the longest wait in the process.
Phase 4: Installation (1-3 days)
This is the exciting part! The actual installation typically takes:
- 1 day: 5-10 windows (small home or condo)
- 2 days: 10-20 windows (typical 3-4 bedroom home)
- 3 days: 20+ windows or complex projects (large estate, multi-story)
Our crews work efficiently while respecting your home — drop cloths, dust barriers, and daily cleanup are standard.
Phase 5: Inspection & Close-out (1-2 weeks)
After installation, the building department schedules a final inspection. The inspector verifies that all windows match the approved NOA products and are installed per manufacturer specifications.
