The short version
Florida has no state chimney-sweep license, so check what can be checked: insurance, what the visit includes, and findings you can see for yourself. Gas-line and roofing work are licensed trades, so verify those licenses when a job includes them. Voluntary credentials such as CSIA and NFI belong to individuals and can be looked up by name.
Start with what Florida does and doesn’t license
Different parts of chimney and fireplace work fall under different rules in Florida. Knowing which is which tells you what to ask for, and stops you from asking for a license that doesn’t exist while missing one that does.

| Type of work | State license? | How to check |
|---|---|---|
| Chimney sweeping, cleaning and inspection | No state chimney-sweep license | Ask about voluntary certification (CSIA) and insurance |
| Natural gas piping and connecting gas appliances | Yes: plumbing or mechanical contractors, licensed by DBPR under F.S. 489 | Search the contractor on the DBPR license lookup |
| Propane (LP gas) piping and appliances | Yes: LP gas licenses issued by FDACS under F.S. Chapter 527 | Ask for the FDACS license and category |
| Structural masonry, chimney rebuilds | No state masonry-specific license; permits may apply | Ask whether a permit is needed and who will pull it |
| Roof covering and roof-to-chimney work tied into a reroof | Roofing is licensed contractor work in Florida | Search the roofer on the DBPR license lookup |
Sweeping and inspection: no state license
Florida doesn’t issue a license for chimney sweeping or chimney inspection. That means a company can’t show you a state sweep license, and one that claims to hold one should be able to tell you exactly what it is. In place of a license, look at voluntary certification, insurance and the quality of what the company gives you in writing.
Gas work: licensed, and split by fuel
Gas is where licensing is firm. Under F.S. 489.105, the scope of a plumbing contractor includes gas lines and liquefied petroleum gas venting, and a mechanical contractor may install natural gas and LP fuel lines within buildings. Both are licensed by the Department of Business and Professional Regulation (DBPR). Propane work is also regulated by the Florida Department of Agriculture and Consumer Services (FDACS) under Chapter 527, which issues LP gas licenses, including installer categories for piping and appliances (FDACS LP Gas Licenses). If a job involves running, altering or connecting a gas line, ask which of these licenses covers it and check it.
Masonry, structure and permits
Florida has no state license category specifically for masonry, and a 2021 state law (HB 735) preempted local governments’ own specialty contractor licenses, a change local building departments have been implementing since (Miami-Dade County notice). So there may be no masonry license to ask about. What still applies is the building permit: rebuilding a chimney, structural repairs and work tied into the roof may need one from your city or county. Ask the contractor whether the job needs a permit and who pulls it, and if you’re unsure, call the building department for your address. If the house is in one of Orlando’s historic districts, exterior changes can also need a Certificate of Appropriateness (City of Orlando).
Checking a Florida license
DBPR’s public license search lets you look up a contractor by name or license number and see whether the license is active. Make sure the name on the license matches the company on your contract.
Voluntary certifications, and how to verify them
Two national organizations certify individual technicians. Certification is voluntary, belongs to a person rather than a company, and must be kept current, so verify it rather than relying on a logo.

| How to verify | CSIA’s “Find a Certified Pro” search (csia.org) | NFI’s “Find an NFI Pro” search (nficertified.org) |

If a company says its technicians are certified, ask for the name of the certified person and whether that person will do or supervise your job, then look the name up. A company can have one certified technician and send someone else. The organizations are described here for reference only; mentioning them isn’t a claim that any particular company, including this one, holds their credentials.
Ask for proof of insurance
Chimney work happens on roofs and ladders. The FTC’s advice for any home improvement job is to consider only contractors who are licensed where required and insured, and to ask for proof of insurance (FTC); the BBB adds that you could face liability if an uninsured worker is hurt on your property (BBB). Ask for a certificate of insurance, check that it’s current and in the company’s name, and ask your own insurance agent if you’re unsure what coverage a contractor should carry.
Red flags
Consumer agencies describe the same warning signs across home services. The FTC lists pressure for an immediate decision, a request to pay everything up front or in cash, and a contractor who shows up saying they’re “in the area” (FTC). The BBB warns specifically about door-to-door chimney solicitation and about choosing a sweep on price alone (BBB).
Be cautious when you see
- A sweep or inspection price far below what others quote, followed by an urgent pitch for a large repair
- Pressure to sign today, or claims that the fireplace will “burn the house down” without a visible explanation
- No findings in writing, no photos, and no way to see the problem yourself
- Payment demanded in full before work starts, or cash only
- Unsolicited door-to-door or phone offers, sometimes bundled with extras such as gutter cleaning
- Vague certification claims with no name you can look up
A low price by itself isn’t proof of anything, and real hazards do exist. The point is to slow down and verify.
Questions to ask before you book
- Who will do the work, and what training or voluntary credentials does that person have?
- Can you send a certificate of insurance before the visit?
- What exactly does the sweep or inspection include: firebox, smoke chamber, full flue, top of the chimney, attic or chase where accessible?
- How will the full height of the flue be checked, and what will I receive afterward?
- Do you work on factory-built (prefab) fireplaces, and how do you source listed parts for my model?
- If you find a problem, will I get the findings and repair options in writing before any work is scheduled?
- Does any recommended repair need a permit, and who pulls it?
- Is any part of the job gas work, and if so, who holds the license for it?
If you don’t know yet which inspection you need, Level 1 vs Level 2 inspections explains the difference, including when a deeper, full-flue inspection is expected.
What a useful inspection report includes
The report is what you’ll use to decide, compare quotes or negotiate a home purchase. Whoever you hire, ask for the findings in writing with photos, and look for these elements:
- The type of system (masonry or factory-built) and, for factory-built units, the manufacturer and model from the rating plate
- Each component checked, from the cap or chase cover down to the hearth, with its condition
- Photos of every problem, so you can see it yourself
- A clear split between safety issues, repairs that can wait, and maintenance
- What could not be seen or reached, stated as a limitation
- Repair options with what each involves, not just a total price
A report like that makes a second opinion easy: another company can read it, look at the same components and tell you whether they agree. For a large repair, getting one is reasonable, and a company confident in its findings shouldn’t object. The parts of a chimney guide can help you follow the terms a report uses.
If you’re told you need a major repair
Stop using the fireplace if a safety issue is named
Don’t burn until the question is settled either way.
Get the findings in writing with photos
Ask which component is damaged, how it was confirmed and what happens if the repair waits.
Get a second look
Share the report with another company and ask for their own assessment of the same component.
Compare scopes, not only prices
Two quotes for “chimney repair” can describe very different work. Line up what each one actually replaces.
For planning, the overview of chimney repair types explains what each common repair involves, and a routine chimney and fireplace inspection or sweep is a low-stakes way to see how a company works before you trust it with anything bigger.
Knowing the parts helps you judge a quote. The chimney repair vs rebuild guide explains how masonry scope is decided, and what happens during a sweep shows what a routine visit should include. If you’ve been told something is urgent, is my fireplace safe to use sets out which findings genuinely mean stop.
