Impact Windows & Doors South Florida Experts

A South Florida Homeowner's Guide to Impact Windows and Doors

An impact window is not just thicker glass. It is a system: two panes of glass bonded to a tough plastic interlayer, set in a reinforced frame and anchored into the wall to a tested schedule. When debris hits it in a storm, the glass may crack, but the interlayer holds the pieces in place and the opening stays sealed. That sealed opening is what keeps wind pressure out of the house — once a window or slider fails, pressure inside the home can lift a roof from below.

The rules depend on your county

Homes in Miami-Dade County and Broward County are in the High Velocity Hurricane Zone, the strictest wind standard in the country, so every product needs an approval that covers HVHZ use. Palm Beach County sits just outside that zone but inside Florida's wind-borne debris region, so impact protection is still required. Either way, the product approval number goes on the permit and the inspector checks it against what was installed.

What changes the price of a project

No two quotes are alike because no two houses are. The biggest factors are the number and size of openings, whether an opening is being enlarged or changed (which turns a swap into a structural job), the glass package — tint, low-E coatings and obscure glass for bathrooms — and the frame finish. Large multi-panel sliding glass doors and oversized impact entry doors cost more than standard windows because the glass and hardware have to resist higher loads. We give you a written, itemized quote after measuring every opening, so you can see exactly where the money goes. For typical numbers, see our 2026 South Florida impact window and door price guide.

Insurance savings and grants

Once every opening is protected and a wind-mitigation inspection is filed, Florida insurers apply opening-protection credits — for many older homes this is the largest discount on the policy. Eligible single-family homes may also qualify for the state's My Safe Florida Home program. We supply the product approvals and closed-out permit the inspector needs, including for impact-rated garage doors, which count as an opening too.

How a project runs with us

1. Free in-home visit. We measure every opening and talk through glass, colour and style options.
2. Written quote listing each window and door with its product approval.
3. Permit. We prepare and submit it to your city's building department.
4. Manufacturing. Units are built to your measured openings — usually the longest step.
5. Installation. Our own crews install and seal each opening; the house is never left open overnight.
6. Inspection and close-out. We meet the inspector and close the permit so it is on record when you sell or refinance.

Repair or replace?

Not every problem needs new windows. A slider that drags usually needs new rollers and a track repair, and a cloudy or cracked pane can often be handled with glass replacement. We will tell you honestly when a repair is the better value — and when an older, unprotected window is costing you more in insurance and cooling than replacing it would.
