Does a 5-Star Rating Mean a Licensed Plumber? I Checked 115 Plumber Listings Around St. Petersburg

When a pipe leaks, many people open a map or review site, search for a plumber and call one of the first names with five stars. The stars come from customers and tell you how a visit went for the people who wrote a review. Whether the company holds a Florida plumbing license is a separate question, and only the state's records answer it. That difference matters most when a job goes wrong: Florida's fund for homeowners who lose money to a contractor pays nothing if the contractor wasn't licensed.

On October 1, 2026, we reviewed the plumber listings that a popular online maps service showed in and around St. Petersburg, Florida, along with their star ratings and how many people had rated each one. For this article, I checked the 115 plumber listings in and around the city against the state's contractor license records and its business registry. Below, I show seven quick checks and how to look up a license for free.

The Short Answer

Of the 39 listings with a perfect 5.0, I found an active Florida plumbing license for 22. For listings rated 4.8 or 4.9, it was 24 of 28. Six of the other 17 five-star listings belong to drain, sewer camera, leak detection or pipe tapping specialists, and some of that work doesn't need a state plumbing license. A license I couldn't find in the records doesn't prove that a company works without one, and a star rating can't tell you either way.

How to Read a Plumber's Star Rating Before You Call

Each check below is based on what I found in the 115 listings, and you can do all seven from your phone before you call.

1. Count the reviews before you look at the stars

A 5.0 average from three reviews and a 4.8 from three hundred are different kinds of evidence. Twelve of the 39 perfect ratings I checked rested on five reviews or fewer, and three on a single review. I found an active plumbing license for only four of those twelve. With a handful of reviews, treat the average as a first impression.

2. Read the one-star reviews

A plumber with a long record almost always has a few unhappy customers. Of the 39 listings with 50 or more reviews, 36 had at least one one-star review, including 24 of the 27 rated 4.8 or higher. Read what went wrong: a late arrival is a smaller problem than a leak that came back. If the owner replied, the reply shows how the company handles a complaint.

3. Read the newest reviews and look for a company name

Recent reviews show that the business still answers calls and who comes out. Look for the name of the company or the technician in the text. A listing that sends your call to a referral service can collect reviews for whichever contractor showed up, and four of the listings link to websites like that. I wrote about these middlemen in Is That "Local" Plumber Really Local?

4. Check whether anyone from the company manages the listing

The maps service marks whether a business has claimed its listing, usually with an invitation to the owner when it hasn't. I found an active license for 7 of the 19 unclaimed listings and for 69 of the 96 claimed ones. An unclaimed listing can still belong to a good plumber who never set it up. It only tells you that nobody from the company has taken charge of it.

5. Check what the business actually does

Some listings in the plumber category belong to companies that only clear drains, inspect sewer lines with a camera or look for hidden leaks. Eleven of the 115 listings belong to specialists like these, including pipe lining and pipe tapping companies. Florida doesn't require a state license for drain cleaning and clearing alone (section 489.105(3)(m), Florida Statutes), so a drain company with five stars and no license number can be legitimate. If a sewer camera inspection finds a broken line, fixing it is plumbing work and needs a licensed plumbing contractor, so check the license of whoever will do the repair before it starts.

6. Make sure the company still exists

A rating stays on a listing after the company behind it stops being active. Eight listings carry the names of companies that Florida's business registry lists as inactive, and I found no active plumbing license tied to those names. Seven of them still showed a star rating. An inactive record can also mean the business now works under another legal name, so ask before you book. Search the name in Sunbiz, the state's business registry, and check that the status is active.

7. Look up the license

Florida requires a licensed contractor to show its license number in every advertisement (section 489.119(5)(b), Florida Statutes), and the state's rules count a website as advertising (rule 61G4-12.011, Florida Administrative Code). If you can't find the number, ask for it, then enter it in the state's Verify a Licensee search. The name on the license can differ from the one on the listing, so ask which company the license belongs to. I walk through the search step by step in How to Check a Plumber's License in Florida, so read it before you hire anyone.

Stars vs. State Records: What I Found

A perfect 5.0 led to a licensed plumber less often than a 4.8 or 4.9

Rated 5.0 (39 listings)

Rated 4.8 or 4.9 (28 listings)

Rated 4.5 to 4.7 (12 listings)

  • Active Florida plumbing license found
  • Drain, sewer camera, leak or pipe lining specialist
  • No license found, a middleman's website, or an inactive company
  • Unclear: a license exists under a related name, holder not confirmed

Ten listings had no rating and aren’t shown. “No license found” means I couldn’t find an active plumbing license by the listing’s name, its website, its trade name owner, its phone number or its address; a company can still work under a license held in another name.

In every rating band, most listings led to a company with an active plumbing license. The share was highest at 4.8 and 4.9 and lowest at a perfect 5.0. That top band also held most of the listings with five reviews or fewer and most of the rated specialists. Low ratings mostly belonged to licensed companies too: I found a license for 7 of the 10 listings rated below 4.0.

Why a Star Rating Can't Show a License

A review describes a visit: whether the plumber came on time, fixed the leak and charged what was quoted. The customer rarely has a reason to look up a license, and the review form doesn't ask about one. A licensed plumber and an unlicensed one can both earn five stars for a quick, clean job. The difference shows up when the work needs a permit or something goes wrong later.

A business can also shape its rating by choosing whom to ask. That maps service's rules, as of October 2026, forbid businesses to ask only satisfied customers for reviews or to pay for them. Federal law covers part of this too: since October 2024, the FTC's rule on consumer reviews has banned businesses from writing or buying fake reviews, paying for reviews that express a particular opinion, and letting their own officers or managers review the business without saying so (16 CFR Part 465). A federal lawsuit filed in May 2026 alleges that one home repair company posted fabricated five-star reviews for listings of businesses that didn't exist. As of October 2026, the case is still pending, and none of the allegations has been proven in court.

What a License Adds

A Florida plumbing license means the state checked the contractor before it could take your job. For a certified license, the applicant needs four years of experience in the trade, or a combination of experience and college credits, and must pass a state exam (section 489.111, Florida Statutes). It also swears to having liability and workers' compensation insurance and meets financial requirements, and it repeats the insurance statement at every renewal. These checks happen when the license is issued or renewed, so they don't prove that the insurance is in force on the day of your job. I described them in more detail in Why We Show License Numbers, Not Just "Licensed" Badges.

If something goes wrong with a licensed contractor, you can file a complaint with the state, and its construction board can discipline the contractor. If a licensed contractor abandons your job or mishandles your money, and you win a court judgment or a board order for restitution, Florida's Homeowners' Construction Recovery Fund may repay part of the loss. It pays nothing when the contractor wasn't licensed (section 489.141, Florida Statutes).

The license record also shows whether the license is current, when the state first issued it and whether the board has disciplined the contractor. I found cases in the board's disciplinary records since July 2021 for only one of the licensed companies behind the listings, and its listing had a 4.9 rating. For whether the plumber shows up on time and charges fairly, read the reviews.

If the Top-Rated Plumber Has No License You Can Find

A search by the listing's name can come up empty even when the plumber is licensed. For at least six of the 76 listings where I found a license, it was held under a different company name: a legal name behind a brand, or the company of the person who qualifies the business. A search by the license number avoids that problem.

If your job legally requires a plumbing license and the company can't give you a license number, or the name it gives doesn't match anything in the state's records, I would not book the visit. The same goes for a listing whose company the state lists as inactive: the phone number may now ring somewhere else, so ask who you're talking to before you share your address.

Florida's Department of Business and Professional Regulation takes complaints about contracting without a license on its unlicensed activity line, 1-866-532-1440, by email at [email protected] and through its online complaint form. A review you believe is fake can be flagged on the site where you saw it, and you can report a business that misled you to the FTC at ReportFraud.ftc.gov.

How This Study Was Done

On October 1, 2026, we reviewed the listings that a popular online maps service showed for St. Petersburg: its business listings within about 9 miles of the city center and up to 300 results of a search for "plumber" there. After removing duplicates, that left 307 places. I kept the 115 whose main category is plumbing, drains or sewers and that sit inside the city limits or within about 2 miles of them; 105 had a rating. Ratings change every day, so these are as of October 1.

I looked for an active certified or registered plumbing contractor license in Florida's records as of October 26, 2026, searching by the license number on the company's website (in pages we saved in October), the listing's name, the owner of the trade name, the phone number in license applications and the street address. I checked by hand every listing the search didn't match and every match that rested only on an address or a generic name. Disciplinary cases come from the state construction board's records for the fiscal years 2021-22 through 2025-26.

I didn't call any of the companies. Sorting a listing as a specialist or as unclear is a judgment, and each rating band holds 10 to 39 listings, so a few listings can move a share by several points. I report only totals and don't name the businesses.

FAQ

Does a 5-star rating mean a plumber is licensed?

No. Customers rate the visit, and the rating doesn't show whether the company holds a Florida license. Among the listings I checked, a little over half of those with a perfect 5.0 led to an active plumbing license. Only the state's license records answer the question.

Are perfect 5-star ratings fake?

Not necessarily, and a rating can't tell you which ones are. Many perfect ratings rest on very few reviews. A plumber with a long record usually has a few one-star reviews among hundreds of good ones, so a 4.8 from a few hundred customers tells you more than a 5.0 from three. Writing or buying fake reviews has been banned by federal rule since October 2024.

How many reviews should a plumber have before I trust the rating?

There's no fixed number. Among the listings I checked, the more reviews a listing had, the more often I found a license behind it. With only a handful of reviews, read them one by one, look at the newest and the lowest, and check the license before you book.

Do drain cleaning companies need a license in Florida?

Florida doesn't require a state license for drain cleaning and clearing alone. Some counties and cities have their own rules, so check with yours. Repairing or replacing pipes and sewer lines is plumbing work, and a company you hire to do it needs a plumbing contractor license.

Why does a highly rated listing belong to a company that's no longer active?

A rating stays on the listing after the company behind it stops operating. Eight of the listings I checked carried the names of companies that Florida's business registry lists as inactive. Search the name in Sunbiz before you call.

Where can I report a fake review or an unlicensed plumber in Florida?

Flag the review on the site where you saw it, and report a business that misled you to the FTC at ReportFraud.ftc.gov. Report contracting without a license to the Department of Business and Professional Regulation at 1-866-532-1440 or through its online complaint form.

This article is general information, not legal advice. Laws change; for a decision about your own project or dispute, check the current law or talk to a Florida-licensed attorney.
