Choosing a Licensed Window Contractor in Florida

Verify an active Florida contractor license

Every contractor performing window and door installation in Florida should hold an active, appropriate license — either a state-level license (such as a Certified Building Contractor or Certified General Contractor) or a local/county-level license where applicable, depending on the scope of work and jurisdiction. Don't take a license number on a business card at face value. The Florida Department of Business and Professional Regulation (DBPR) maintains a free public license search at myfloridalicense.com where you can verify a license is active, check its classification, and see whether any disciplinary actions are on file. This takes a few minutes and is the single most important check you can do before signing anything.

Confirm insurance and bonding

Ask for proof of general liability insurance and workers' compensation coverage (or a valid exemption) directly from the contractor — a certificate of insurance naming you or your address isn't required, but you should be able to get a certificate showing current coverage. If a worker is injured on your property and the contractor doesn't carry workers' compensation, you as the homeowner can potentially bear liability exposure. This is not a step to skip because a contractor "seems established" — ask for the document.

Ask for real, verifiable project references

A contractor with a genuine local track record should be able to provide addresses or contact information for completed projects — ideally ones you can drive by or call about. Be wary of a contractor who can only offer stock photos, out-of-state project examples, or vague testimonials without any way to verify them. Recent Florida-specific projects, particularly ones involving impact-rated products, are the most relevant reference point for your own project.

Insist on real product-approval documentation — not a verbal claim

Any contractor proposing impact-rated windows or doors should be able to hand you the actual Florida Product Approval or Miami-Dade Notice of Acceptance (NOA) documentation for the specific product and configuration being installed — not just tell you it's "hurricane rated" or "impact glass." This documentation should match the specific size, configuration, and design pressure rating for your actual openings, not just be a general brand claim. If a contractor can't produce this documentation, or gets vague when asked for it, that's a serious warning sign — the documentation is a public record tied to a specific tested product, and a legitimate contractor works with it routinely.

Red flag: storm-chaser urgency tactics

Be cautious of any sales approach built around urgency — "this price is only good today," door-to-door solicitation immediately after a storm, or pressure to sign before you've had time to verify the license or get a second quote. Legitimate contractors doing quality work don't need to manufacture time pressure to get your business, and Florida's structural, code-driven permitting process doesn't move at "sign today" speed anyway.

Red flag: no local, verifiable address

A company with a real physical presence in Central Florida — an actual office or showroom address, not just a P.O. box or a residential address used only for licensing purposes — is generally more accountable than one that appears and disappears between storm seasons. Check that the business address on their license matches what they advertise, and that it's a real, findable location.

Red flag: vague financing terms

If financing is part of the conversation, ask for the actual terms in writing — interest rate, term length, and total cost — before signing anything. Be cautious of financing pitches that emphasize only a low monthly payment without disclosing the full terms, or that pressure you to commit to financing before you've compared it to other options.

Questions to ask before you sign

Before signing a contract, ask: What is your Florida contractor license number, and can I verify it myself? Can you provide current proof of general liability and workers' compensation insurance? Can you show me the Florida Product Approval or NOA documentation for the specific product you're proposing for my openings? Who pulls the building permit, and is that included in the price? What is the manufacturer's warranty versus your workmanship warranty, and can I get both in writing? What is the payment schedule, and does it comply with Florida's contracting deposit practices? A contractor confident in their work will answer all of these directly and without hesitation.
