Hiring the right plumber protects your home and your wallet. The good news is that vetting one in Florida takes about ten minutes if you know what to check. Use this checklist before you book any job, from a quick drain cleaning to a full repipe.
Why licensing matters in Florida
Florida regulates plumbing contractors at the state level through the DBPR's Construction Industry Licensing Board (CILB), and they must follow the Florida Building Code. Many counties also run their own competency-card and inspection programs within their jurisdiction.
A Registered (RF) contractor must hold the local county competency card for the jurisdiction they work in, while a Certified (CFC) contractor is licensed to work statewide. If your county licenses separately, confirm the contractor holds the local card.
A licensed plumber has met training and exam requirements and carries accountability if something goes wrong. An unlicensed handyman may be cheaper today and far more expensive after a failed repair floods a finished floor.
The vetting checklist
Run through these seven items for every plumber you are considering.
- 1License. Ask for the Florida DBPR/CILB license number (Certified CFC or Registered RF), plus the county competency card if your county requires one.
- 2Insurance and bond. Confirm general liability insurance and bonding, and ask for a certificate if the job is large.
- 3Written estimate. Require an itemized, written estimate before work begins. See typical numbers in our drain cleaning cost guide.
- 4Reputation. Read recent reviews and ask for references on bigger jobs.
- 5Permits. For water heaters, repipes, sewer work, and gas lines, a permit and inspection are often required. A pro who skips permits is a warning sign.
- 6Warranty. Ask what is warrantied, for how long, and whether it covers both parts and labor.
- 7Payment terms. Reasonable deposits are normal on large jobs. Full payment in cash before any work is not.
How to verify a license yourself
You do not have to take a plumber's word for it. Both the state and the city publish public lookups.
State (Florida DBPR) license
Search the Florida DBPR Plumbing Program for the license number the plumber gives you, and confirm the name matches the business.
County competency card
For counties that license separately, check that county's contractor and permit lookups -- for example, Miami-Dade County. Every business in our directory shows the public registry data we matched it to, and you can read how we do that on our verification page.
Red flags to walk away from
Any single red flag below is a reason to pause. Two or more, and you should keep looking.
- Refuses to provide a license number or proof of insurance
- Will only give a price in person and pressures you to decide on the spot
- Demands full payment in cash before starting
- Has no written estimate or contract
- Wants to skip permits on work that legally needs them
- Quotes a price far below every other bid, which often means an unlicensed crew
If you are dealing with a true emergency such as a burst pipe, the pressure is real, but the fundamentals still apply. Our plumbing emergency guide explains how to act fast without getting taken advantage of.
Questions to ask before they start
A short conversation prevents most disputes.
- Is this price flat-rate or hourly, and what could change it?
- Who pulls the permit, and is the inspection included?
- What warranty comes with the parts and the labor?
- Will you haul away the old water heater, fixture, or debris?
- Who is the actual licensed person on site, not just the company name?
After you hire
Keep the signed estimate, the permit, and the final invoice together. If a repair fails inside the warranty window, those documents are your leverage.
