How to Vet a Licensed Plumber in Florida

Every plumber working legally in Florida holds a license issued by the state, and the state runs a free public lookup you can use to verify that license before you let anyone step inside your home. This guide walks through that lookup step by step, explains what to check on their insurance, lists the red flags that show up in quotes and cold calls, and gives you a short pre-hire checklist you can screenshot and use the next time you hire.

Shamrock Plumbing has served Orlando and Central Florida since 2003 under Florida License CFC1426719. We wrote this guide because we spend a lot of time cleaning up after unlicensed work, and every homeowner we help wishes they had done the 60-second license check before they signed. If you have questions on anything in here, phone (407) 326-3056 or use the contact form on the site.

Why Florida Requires Plumber Licensing

In Florida, plumbing is regulated by the Department of Business and Professional Regulation (DBPR) through the Construction Industry Licensing Board (CILB). The state issues two kinds of plumbing contractor licenses, and it matters which one your plumber holds:

• Certified Plumbing Contractor (CFC prefix): passed the state exam, valid statewide, can pull permits anywhere in Florida. This is the license our team holds.
• Registered Plumbing Contractor (RF prefix): passed a local jurisdiction exam and is limited to the county or city where they qualified. Not necessarily worse, but their scope is smaller and their credentials should match your address.

Why does this matter to you as the homeowner? Three reasons. First, licensed contractors are the only ones who can legally pull permits, which are required for water heater installs, repipes, and most fixture replacements. Unpermitted work often has to be torn out later, at your cost, before you can sell the home. Second, hiring an unlicensed plumber can void your homeowner's insurance for any related claim, so a leak they caused becomes your problem to pay for. Third, Florida runs the Florida Homeowners' Construction Recovery Fund, which reimburses homeowners hurt by licensed-contractor misconduct, but only if the contractor was actually licensed. Skip the license check and you skip all three protections.

How to Look Up a Plumber's License on the DBPR Site (Step by Step)

The DBPR lookup takes under a minute. Here is the exact sequence:

1. Go to myfloridalicense.com in any browser. There is no login and no paywall. This is the official state record.
2. Click "Verify a License." You will get two options: search by name (individual or business) or search by license number.
3. Enter what you have. If you know the CFC or RF number, use that; it is the fastest and most exact. Otherwise search the business name. A legitimate plumber's license number is on their truck, their invoice, and usually the footer of their website, so it should not be hard to find. If they will not tell you their number, that is your first red flag.
4. Read the result. You are looking for four things: the license type (CFC certified is broadest), the license status, the expiration date, and any disciplinary actions or complaints on the record. The name on the license should match the business you were quoted by.
5. Confirm the status is "Current, Active." Anything else is a stop sign. See the table below for what each status actually means.

As a working example, if you ran this search on Shamrock Plumbing you would land on license CFC1426719, issued to a Certified Plumbing Contractor, with a Current, Active status. That is what a clean record looks like. If your plumber's record does not, or if the license simply is not there, do not sign.

How to Verify Insurance (Not Just the License)

The license tells you the state has vetted their credentials. Insurance is what protects you if something goes wrong on your property. Ask any plumber you are considering for a Certificate of Insurance, sometimes called a COI. A real one is a one-page PDF issued by their insurer, showing coverage and current dates. You want to see two things on it:

• General Liability insurance, which covers damage to your property caused by their work. Coverage limits vary; ask for what they carry and get it in writing.
• Workers' Compensation insurance, which covers the plumber and their crew if someone gets hurt on your property. Under Florida law, any construction employer with one or more employees must carry workers' comp coverage. If a plumber tells you they are exempt, ask for their exemption certificate. If they cannot provide either, they are not a legitimate operation and you are on the hook if their worker gets hurt in your home.

A quick test: ask if you can be added as "certificate holder" on the COI. Legitimate contractors do this routinely. It costs them nothing, gives you notification if their coverage lapses, and screens out contractors who are pretending to be insured. If they hesitate or refuse, that tells you something.

Red Flags to Watch For

The scams are usually not clever. They tend to follow the same handful of patterns, and knowing them ahead of time is most of the defense.

Red Flags in the Quote

• Cash-only, or refusal to give a written estimate. Legitimate contractors write things down because that protects them too.
• Estimate massively lower than every other quote you got. In plumbing this almost always means the contractor is unlicensed, uninsured, cutting materials to sub-code, or planning to add charges later. Cheap now, expensive later.
• Vague scope. No materials listed, no permit language, no warranty terms, no timeline. A real quote is itemized.
• Large deposit up front. Florida law caps the deposit on residential construction work over a certain dollar amount at ten percent, and applying permit fees on top. Anyone asking for half or more in advance is either unaware of Florida law or does not intend to comply with it.
• High-pressure sign-today discount. A legitimate quote is good for weeks. "This price is only good if you sign today" is a sales tactic, not a business practice.
• No mention of permits on work that clearly needs one, like a water heater install, a repipe, or a sewer line replacement. Skipping the permit means skipping the inspection.

Red Flags on Door Knocks and Cold Calls

• Uninvited door-to-door plumbers. Established local plumbers rarely canvass neighborhoods, so a cold knock is worth extra scrutiny even if the company turns out to be legitimate.
• "We noticed a problem at your neighbor's house." A pitch designed to create urgency about a problem you have not verified.
• Storm-chasers after weather events. Out-of-state trucks appear after storms, take deposits, and vanish. Stick with a plumber whose address is local and whose reviews go back years.
• Vague or generic business name, no local address, and a truck with no company branding.
• Zero reviews online, or only a handful of five-star reviews all posted in the same week.

The Pre-Hire Checklist

Before you sign or hand over money to any plumber in Florida, run this list. If any line has a question mark next to it, get answers before you commit. For repipe or whole-home work specifically, our companion guide on how to choose a repipe company in Orlando (and what your quote must include) goes even deeper.

• Verified their CFC or RF license as "Current, Active" on myfloridalicense.com
• Received a Certificate of Insurance showing current General Liability and Workers' Compensation
• Received a written, itemized quote with materials, labor, and warranty terms in writing
• Confirmed who pulls the permit if one is required, and that a permit is being pulled at all
• Deposit request is within Florida legal limits (no more than the state cap plus permit fees)
• Independently checked reviews on Google and the BBB, not just the reviews on their own site
• Contractor gave a physical business address and the truck carries clear company branding
• Timeline and payment schedule are tied to milestones, not paid in full up front

If a Central Florida plumber checks every box, you can hire with confidence. If they miss one, you have specific questions to ask. If they miss three or more, keep looking.
