Impact window prices per window
These are the ranges we quote across Broward, Miami-Dade, and Palm Beach. Where your window lands inside the range depends mostly on its size and the brand you pick.
| Window | Price per window | Permit fees |
|---|---|---|
| Average-size impact window | $1,500 to $2,000 | Separate |
| Larger impact window | $2,500 to $3,000 | Separate |
| Impact doors and sliding glass doors | Quoted on site | Separate |
What a whole house costs
Most people replace every opening at once so the home qualifies as fully protected. These examples use the ranges above. Your quote depends on the exact sizes and products.
| Home | Math | Estimate before permit fees |
|---|---|---|
| Condo unit, 4 average-size windows | 4 × $1,500 to $2,000 | $6,000 to $8,000 |
| 3-bedroom ranch, 10 average + 2 larger windows | 10 × $1,500 to $2,000 + 2 × $2,500 to $3,000 | $20,000 to $26,000 |
| 4-bedroom two-story, 16 average + 4 larger windows | 16 × $1,500 to $2,000 + 4 × $2,500 to $3,000 | $34,000 to $44,000 |
Add any impact doors or sliders, which we price after measuring, plus your city's permit fee.
What changes the price of an impact window?
Size and brand move the price the most. Several other things also count:
- Wind zone. Miami-Dade and Broward are in the High-Velocity Hurricane Zone, which requires products approved for that zone. Palm Beach County is outside it, so more product approvals qualify there.
- Design pressure. Waterfront homes and upper condo floors face stronger wind loads and may need higher-rated units.
- Window style. Single-hung, horizontal roller, casement, and fixed picture windows are priced differently.
- Glass and frame options. Low-E or tinted glass and frame colors change the product cost.
- Opening conditions. Resizing an opening or repairing damaged stucco around an old frame adds work.
- Approvals. Condo and HOA boards often require specific styles or colors and paperwork before work starts.
Why permit fees are separate
Window and door replacement in South Florida needs a building permit, and each city or county sets its own fee. Because that fee is not ours, we list it separately on your quote. We still pull the permit, schedule the inspection, and hand you the paperwork when it passes.
Do impact windows pay for themselves?
Partly, for many homeowners. Florida requires insurers to offer premium discounts for qualifying wind-mitigation features, and protected openings are one of them. Savings depend on your home, a wind-mitigation inspection, and your insurer. Impact glass also removes the cost and work of putting up shutters before every storm.
