Windows are only as good as their installation. Use this checklist when you pick a contractor.
1. Verify the license
Florida requires contractors to hold the proper license. Check the license number on the state licensing website, confirm it is active, and make sure it matches the company on your quote. Our license number is #SCC131153391.
2. Confirm insurance
Ask for a certificate of general liability insurance and proof of workers' compensation. Without it, you could be liable for a worker injured on your property.
3. Read the reviews and ask for references
Look at recent Google reviews, how the contractor replies, and ask for references from similar projects. Photos of finished work are a good sign.
4. Check product approvals
The quote should name the manufacturer, product line and NOA or Florida Product Approval. See how to tell if windows are impact rated.
5. Get everything in writing
A written scope, price, timeline, permit responsibilities and warranty. Compare quotes using our checklist.
6. Look for permit handling
A professional pulls permits and schedules inspections. See why permits matter.
7. Watch for red flags
High pressure, no license number, huge upfront payments. See red flags.

Understanding Florida license types
Florida licenses contractors by category, such as certified and registered contractors with different scopes. Glazing and window installation fall under specific categories. When you look up a license, check the license type and status, the qualifying business name, and whether there are disciplinary actions listed.
What to look for in reviews
- Recent reviews that mention the type of project you need.
- How the company responds to problems, not just five-star comments.
- Photos or details that show real work.
- Consistency: a steady stream of reviews over time looks more reliable than a sudden burst.
Meet the people who will do the work
Ask who will measure, who will install and who is your point of contact. Smaller firms often have the owner involved from start to finish, which can mean clearer accountability.
Compare more than price
- How quickly do they respond to your calls and emails?
- Is the quote detailed and clear?
- Do they explain the product and permit process without pressure?
Trust your instincts
If something feels off, such as pressure, vague answers or reluctance to put things in writing, look elsewhere. See red flags and questions to ask.
A one-page checklist
- License verified and active.
- Insurance certificate received.
- Three recent references or reviews checked.
- Written quote with product approvals.
- Permit and inspection responsibilities clear.
- Warranty terms in writing.
- Payment schedule that makes sense.
- Clear schedule and point of contact.
Visit a finished job
If possible, ask to see or hear from a customer whose installation is several months old. The first week can look perfect. After a rainy season, a customer can tell you whether leaks or problems showed up, and how the contractor responded.
Frequently Asked Questions
How do I check a contractor license in Florida?
Search the contractor on the state licensing site (myfloridalicense.com) and confirm the license is active and matches the business name.
Should I ask for insurance proof?
Yes. Ask for a certificate of liability insurance and workers compensation coverage or exemption.
Are online reviews enough?
They help, but also ask for references and photos of similar completed work.
Is a local contractor better than a large national company?
Not automatically. What matters is license, experience, references and service. Local firms may be more responsive and know local permit offices.
