Connecticut Licensed Plumbing Contractors
U.S. · 4,266 locations

There are 4,266 Connecticut Licensed Plumbing Contractors as of October 2026. They are in 31 states. Connecticut has the most, with 3,675.

This is the complete licensed universe of plumbing contractors in Connecticut, not a directory of the ones who chose to be listed: every active license the Connecticut Department of Consumer Protection publishes in its public extract, reduced to one row per licensed firm or individual at an address.

More about this list

4,266 records. 1,080 records carry a separate business name from the licensed individual. Classifications in the file: PLUMBING & PIPING UNLIMITED CONTRACTOR (2,817), PLUMBING & PIPING LIMITED CONTRACTOR (1,220), FIRE PROTECTION UNLIMITED CONTRACTOR (381), MEDICAL GAS & VACUUM SYSTEMS CONTRACTOR (118). 611 licensees list an out-of-state address (contractors licensed in Connecticut but based elsewhere); the state column identifies them so they are one filter to drop. Each record carries the state license number, so it joins cleanly to permit data, insurance certificates and other state files, and the expiration date, so you can target renewals. Buyers use it for distributor and manufacturer territory planning, dealer-program recruitment, insurance and financing prospecting, and roll-up sourcing in a fragmented trade. Association lists such as our ACCA member dataset cover the engaged slice; this covers everyone the state allows to pull a permit. Refreshed weekly from the board's extract.

Using ChatGPT, Claude or an API?

No setup needed. Ask ChatGPT or Claude your question about the Connecticut Licensed Plumbing Contractors and give it this page: it can open https://locationlists.com/find?dataset=connecticut-plumbing-contractor-list with the filters you need and show you the count and price.

Using ChatGPT or Claude? Tell it to answer from locationlists.com/find — no account, no connector.

How assistants ask

No connector needed. Any AI assistant can answer from this site with a web link, no connector, no account: open https://locationlists.com/find with the question as query parameters.

If a question needs filtering, distance, drive time, combining lists or a price, open a /find link: either put the question itself in q=, or build the structured link. The answer does not need an API, a connector or an account.

Simplest, the question itself: https://locationlists.com/find?q=<the question in plain words>

Or set the parts yourself: https://locationlists.com/find?dataset=<slug>&state=<ST>&city=<city>&county=<county>&zip=<zip>&near=<place or zip>&radius=<miles>&drive=<minutes>&where=<column>:<op>:<value>&total=<rows>

Leave out what the question does not need. Use radius for straight-line miles or drive for minutes of driving (5 to 60), not both; near can name several places separated by | to reach from any of them. To ask about several lists at once, use datasets with two or more names, or category with a kind of business. To compare two lists, add relate=nearest and the other list with b. in front of its parameters. To count by area, use areas=county (or zip, state, metro). To keep only places whose county, ZIP code, metro area or state meets a Census figure, add area_where (for example county:population>1000000); with areas, per=100000 gives counts per 100,000 residents.

Links an assistant can open, each showing how many rows match, a few preview rows and the price for just that part:

  • The whole list: add a city, state, ZIP code or distance: https://locationlists.com/find?dataset=connecticut-plumbing-contractor-list

Optional: connect for repeat use or wallet payments:

Read https://locationlists.com/skill.md and follow the instructions to connect LocationLists. Then show me the Connecticut Licensed Plumbing Contractors list.

Your assistant will walk you through setup and show you the price before you pay.

?Frequently Asked Questions

How many Connecticut Licensed Plumbing Contractors are there?

There are 4,266 Connecticut Licensed Plumbing Contractors as of October 2026. They are in 31 states. Connecticut has the most, with 3,675.

Is this the same as the state's license lookup?

It is the same underlying data, taken from the board's bulk public extract rather than one-at-a-time lookups, and reshaped to one row per licensed firm or individual at an address with a trade column and a certified/registered class. The lookup shows one license at a time; this is all of them in one file, refreshed weekly.

Does every record have a phone number and a business name?

Only where the board publishes them. State boards license the qualifying individual, and many file an individual name and address rather than a company name. The name column uses the business name when one is on file and the licensee otherwise; licenseeName always carries the individual. Phone is present only for boards that publish it.

Why are some addresses outside Connecticut?

Contractors can hold a Connecticut license while being based in another state, common near state lines and for national firms. They are real Connecticut licensees, so they are included, and the state column makes them a one-filter exclusion if you only want in-state locations.
