Impact Windows and Doors Across Miami-Dade County
Miami-Dade is the toughest county in the country to put a window into, and that is not an exaggeration. The entire county sits inside the High Velocity Hurricane Zone defined by the Florida Building Code, which means every exterior window, door and sliding glass panel has to pass the large-missile impact and cyclic pressure testing the HVHZ demands. Products are approved through Miami-Dade's own Product Control program and carry a Notice of Acceptance — an NOA number that goes on the permit and that the inspector checks against what is physically installed.
For homeowners this has two practical consequences. First, a window bought from a big-box store or online without a valid Miami-Dade NOA simply cannot be permitted here. Second, the approval is specific: it lists the maximum size, the anchoring schedule and the design pressures a unit is rated for. An installer who ignores the anchoring schedule fails inspection even with a perfectly good product. We size, specify and anchor every opening to its NOA so the inspection is a formality rather than a gamble.
Coastal exposure from Key Biscayne to Sunny Isles
Barrier-island and bayfront properties — Miami Beach, Surfside, Bal Harbour, Bay Harbor Islands, North Bay Village, Key Biscayne and Sunny Isles Beach — live with salt spray every day. Salt is what destroys window hardware long before the glass fails: rollers seize, locks pit and mill-finish aluminium chalks. On these addresses we specify marine-grade finishes and stainless fasteners, and we size units to the higher design pressures that taller oceanfront elevations require.
Condominiums and the milestone inspection law
Since the Surfside collapse, Florida law requires milestone structural inspections for condominium and cooperative buildings three stories and taller, and many Miami-Dade associations are now scheduling envelope work alongside them. Unit-owner window and slider replacements in a condo still need association approval and must match the building's approved elevation. We work with management companies regularly and provide the NOA, finish and shop-drawing documentation boards ask for.
Single-family homes inland
West of I-95 the housing stock changes. Much of Hialeah, Miami Springs, Westchester, Sweetwater and Kendall was built between the 1950s and the 1980s with awning, jalousie and single-hung windows that offer no impact protection at all. These are the homes where replacement pays back fastest: insurers apply wind-mitigation credits once opening protection is documented, and older single-family homes are exactly the profile the My Safe Florida Home program was built to help. Further south, in Cutler Bay, Palmetto Bay, Homestead and Florida City, many homes were rebuilt after Hurricane Andrew and now have first-generation impact products that are due for replacement.
Permitting across 34 municipalities
Miami-Dade has dozens of separate building departments — each city issues its own permits, and unincorporated areas are handled by the county. Submittal requirements, fees and inspection scheduling differ from one to the next. We pull the permit in the correct jurisdiction, schedule the inspection and close the permit out, so the work is recorded properly when you sell or refinance.

Common Questions from Miami-Dade County Homeowners
Can I buy impact windows online and have them installed in Miami-Dade?
Only if the exact product carries a current Miami-Dade Notice of Acceptance that covers the size of your opening. Many imported or online-only windows do not, and a building department will not issue a permit for them. We check the NOA against every opening before anything is ordered.
If I have impact windows, do I still need hurricane shutters?
No. Approved impact glazing counts as opening protection on its own, which is why so many Miami-Dade homeowners replace shutters with impact windows — nothing to put up or store before a storm.
How long does a window permit take in Miami-Dade?
It depends on the municipality. Some cities turn a residential window permit around in days; busier departments take a few weeks. Manufacturing lead time usually runs in parallel, so the permit is rarely what sets the install date.
I own a condo unit. Can I replace my own windows and slider?
Usually yes, but you need association approval first, and the new units must match the building's approved elevation and finish. We provide the documentation boards ask for and coordinate with building management on access and elevator use.
