TL;DR: Not every company advertising hurricane window installers in Florida is licensed to pull permits or install code-compliant product. Before you sign a contract, verify the contractor license, confirm the window carries a current Florida Product Approval (NOA), and make sure the installer pulls their own permit. Those three steps filter out about 80% of the bad actors we see in Palm Beach and Broward County.
What You Need Before You Start Shopping
Have these items ready before you talk to a single company. It keeps the conversation honest and speeds everything up.
- Your property address and year built. Older homes sometimes have non-standard rough openings that affect which frames fit without expensive structural work.
- Your current window count and approximate sizes. Even rough dimensions help an installer give you a meaningful ballpark.
- Your insurance carrier and policy number. Some insurers require specific impact ratings for the discount to apply. Know what your carrier wants before you select product.
- A copy of any previous permit history. Pull it from your county building department online portal. If a prior installer never got a final inspection, that becomes your problem when you sell.
- A budget range you are comfortable sharing. Installers who refuse to discuss budget in general terms are selling, not consulting.
Step 1: Verify the Contractor License Before Anything Else
This is where most homeowners skip ahead too fast. In Florida, anyone doing structural window replacement must hold a state-issued Certified Contractor license (CBC prefix) or a Registered Contractor license valid in your county. Subcontracting to an unlicensed crew is common and illegal.
Go to the Florida Department of Business and Professional Regulation website and search the company name AND the individual license number they give you. Confirm the license is active, not expired, and has no disciplinary history.
Also confirm they carry general liability insurance and workers' compensation. Ask for a certificate of insurance naming you as the certificate holder. If they hesitate, walk away.
Here's what we actually see on real jobs: a homeowner gets a low bid from a company that looks legitimate online, but the installer who shows up is a sub working under someone else's license. When there's a leak or a code failure, nobody owns it.
Step 2: Confirm Florida Product Approval (NOA) on Every Window and Door
Impact windows sold in Florida must carry a Notice of Acceptance (NOA) issued by Miami-Dade County or a statewide Florida Product Approval number from the Florida Building Commission. These are not the same thing, and the distinction matters.
Miami-Dade NOA approval is the gold standard for High-Velocity Hurricane Zone (HVHZ) product. If you live in Broward County, you are in the HVHZ. Parts of Palm Beach County are not HVHZ, but many installers use HVHZ-approved product throughout both counties because it simplifies permitting.
Ask every installer: "What is the Florida Product Approval number for the specific window you are proposing?" Then look it up at the Florida Building Commission product approval search. Confirm the approval is current and matches the size range you need.
Cheaper outfits sometimes propose product with approvals that have lapsed or that technically do not cover the large openings in your home. That gets caught at inspection, delays your project, and means the windows have to come back out.

Step 3: Make Sure the Installer Pulls the Permit
In Palm Beach and Broward County, a permit is required for window replacement. Full stop. Any installer who suggests you can skip the permit to save money or move faster is exposing you to serious risk.
Without a permit and final inspection:
- Your homeowner's insurance claim can be denied if the installation was unpermitted.
- You may have to remove and reinstall windows when you sell.
- The wind-mitigation credit with your insurer is not valid.
Ask the installer: "Will your company pull the permit, or do I need to do that?" A licensed contractor should pull their own permit. If they tell you to pull it as an owner-builder, that is a red flag unless you are genuinely acting as your own contractor and understand the liability.
Permit timelines in Palm Beach and Broward currently run anywhere from a few weeks to a couple of months depending on the municipality. A reputable installer will tell you the honest timeline, not promise a turnaround they cannot deliver.

Step 4: Review the Product and Installation Specifications Together
A proposal should tell you more than just a price. Before you sign, confirm the quote includes:
- The specific window series, frame material, and glass package being installed.
- The fastener schedule. How many anchors, at what spacing, using what hardware. This matters for structural integrity.
- How the installer handles the water-management detail at the sill. Improper sill flashing is the number-one source of post-install leaks we see on homes where we are correcting someone else's work.
- Whether the old frames are being removed completely or if the new frame is being installed over the existing frame (pocket or fin-over). Both methods can be code-compliant, but the homeowner should know which method is being used and why.
If you are also replacing doors, ask whether the same product line applies. Hurricane impact doors carry their own NOA requirements and the installation detail around the threshold is different from windows. A company that does both under one permit pull is usually more efficient.
For sliding glass door openings specifically, make sure the installer is familiar with the track anchoring requirements. Sliding glass doors in HVHZ installations have specific head and sill anchor requirements that not every crew handles correctly.
Step 5: Check References for Jobs Similar to Yours
Ask for three to five references from jobs completed in the past 12 months, ideally in your county. Then actually call them. Ask:
- Did the crew show up when scheduled?
- Was the permit pulled and the final inspection completed?
- Were there any post-install issues, and how were they handled?
- Would you use this company again?
Online reviews are useful but easy to curate. A reference call is harder to fake.
Also ask the installer how long they have been operating under their current license and business name. Companies that rebrand frequently after complaints are a pattern in this industry.
Step 6: Compare Quotes on the Same Specifications
Do not compare a quote on a premium laminated glass system against a quote on a basic impact-rated unit and assume the cheaper one is the better deal. You are comparing different products.
When you get multiple quotes, ask each installer to specify: frame material, glass thickness and interlayer type, DP rating, and the brand or series. Then you can compare apples to apples.
If one quote is significantly lower, ask specifically what product is being used and look up the approval number. Sometimes the gap is legitimate cost efficiency. Sometimes it is a lesser product or an unlicensed crew.
If energy performance matters to you, ask about the SHGC (solar heat gain coefficient) rating. South Florida homes benefit from a lower SHGC to reduce cooling loads. Our energy efficient windows page explains how that rating works and what to look for in a hot climate.
Common Mistakes Homeowners Make Choosing Hurricane Window Installers
Choosing on price alone. The lowest bid almost always means something is missing: permit costs excluded, unlicensed labor, lesser product, or incomplete sill flashing detail.
Not verifying the license before signing. Takes five minutes online and saves enormous grief.
Assuming impact-rated means code-compliant for their specific county. Product approval has jurisdictional scope. Confirm the NOA covers your county and your opening sizes.
Skipping the permit to move faster. The permit is what makes the installation legal, insurable, and transferable when you sell.
Not asking about post-install inspection. Find out who coordinates the final inspection and who is responsible if the inspector requires corrections.
Replacing windows without asking about doors. If your doors are 20 years old and your windows are new, your weakest opening is now the door. A window and door replacement project done together is more efficient and gives you complete opening protection.

Frequently asked questions
How do I verify a hurricane window installer is licensed in Florida?
Go to the Florida Department of Business and Professional Regulation website and search the company name and license number. Confirm the license is active, in good standing, and covers the type of structural work being done. Also request a certificate of insurance for general liability and workers' compensation before signing anything.
What is an NOA and why does it matter for hurricane windows?
NOA stands for Notice of Acceptance, issued by Miami-Dade County, and it certifies that a window product has passed rigorous impact and pressure testing for High-Velocity Hurricane Zone use. Without a valid NOA or Florida Product Approval number, the window is not code-compliant in Broward County and much of Palm Beach County. Always ask for the approval number and verify it yourself on the Florida Building Commission website.
Do I need a permit to replace windows with impact windows in South Florida?
Yes. Window replacement is a permitted structural alteration in both Palm Beach and Broward County. A licensed installer must pull the permit and obtain a final inspection. Skipping the permit can invalidate your insurance coverage and create problems when you sell the home.
How long does hurricane window installation typically take in Palm Beach or Broward County?
The installation itself usually takes one to three days depending on the number of openings and any structural complications. Permit review timelines vary by municipality and currently run from a few weeks to a couple of months. Any installer who promises a very fast permit turnaround without knowing your specific city is overpromising.
Is it better to replace windows and doors at the same time?
In most cases, yes. Combining window and door replacement into one permitted project reduces mobilization costs and ensures all openings are brought up to current code at once. It also gives your insurance carrier a cleaner wind-mitigation report, which can maximize any applicable discount.
What should I look for in the sill detail during installation?
Proper sill flashing is the detail most often skipped by less experienced crews. The sill should have a sloped bed of approved sealant, a properly lapped flashing membrane, and no gaps where water can track behind the frame. Leaks from improper sill detail are the most common complaint we see when homeowners call us to fix someone else's installation.
