Hiring a window installer in Miami: the license, the NOA, the permit, and what 4,900 window permits show

Miami windows and doors in numbers

Filing peaks in March (index 119), well before hurricane season, and is lowest in December (85). Prices by firm are on the Miami windows cost page; national ranges in window replacement cost.

Which license a Miami window installer needs

Windows are a local specialty in Miami-Dade. Miami-Dade's Contractor Licensing Section licenses "contractors and tradesmen working in Miami-Dade County" in building, building specialty and other categories (Miami-Dade County, read 23 October 2026), and a window firm works under a county certificate of competency or a Florida contractor license.

The five-minute check:

1. Get the license number and the qualifier's name from the quote.
2. Run the Contractor Information Search on Miami-Dade's BCCO Contractor Search, then the Contractor Complaint Search on the same name. Or call 786-315-2880.
3. If the license is a state one, search it on DBPR's Verify a Licensee.

The permit rule for Miami window replacement

The City of Miami treats exterior windows and doors as a building permit. Its applicant checklist asks for a "Current Miami Dade County Notice of Approval (NOA) Product Approval" or a Florida DBPR product approval, which "Cannot be expired, must be for the current Florida Building Code in effect", and which must show the design pressures, the size of each unit, all mullions and the glass type and thickness. The inspections listed are the window/door buck and the final (City of Miami, read 23 October 2026). Miami-Dade's own windows page says the same thing about NOAs and adds that Florida Building Commission approvals are acceptable (Miami-Dade County, read 23 October 2026).

So ask for the NOA number of every model in your quote before you sign, and check that the sizes on the NOA cover your openings. Once the job is booked, search your address in the City's iBuild portal and open Inspections to see the buck and final results. Rules in other cities: do I need a permit for window replacement.

Red flags in the Miami record

• No NOA or product approval number in the quote. Without it the window cannot pass the permit review.
• No license found on BCCO or DBPR. Ask for the qualifier's name; 7.0% of window firms had no license match by name in our file, usually because they permit under a trade name.
• A finished share under 93.1%. That is the 10th-percentile line among the 45 Miami window firms with 10 or more permits. Where nearly every permit reaches a final, a firm with several open ones stands out.
• A firm that went quiet. 26 window firms with 5 or more permits filed none in the last 12 months.
• A price far outside $8,000 to $19,106 without a reason in the number of openings, doors or a large slider.

What the Miami record does not tell you

A final means the City's inspector passed the installation; it does not check the price, the warranty or the insurance discount paperwork. Our file is the City of Miami only, not Miami Beach, Coral Gables or unincorporated Miami-Dade, which have their own building departments. Shutters and doors are in the same trade as windows here. License status is our match to Florida DBPR and county files by name; check BCCO yourself. Roofing in Miami is covered in hiring a roofer in Miami, and state rules in how to check a contractor's license in Florida.
