Licensing

What each state requires, where we hold registration, and how to get our registration numbers. We do not advertise into a state before its registration is in place.

How registration controls what is published

Each of the four states we cover treats advertising as a regulated act for home improvement contractors. A local service page is an advertisement. So a state's area pages are built only once its registration is recorded in our site configuration, and until then that state stays unpublished rather than appearing with a placeholder.

This is enforced in the build rather than by policy. The site will not generate pages for a state whose licence fields are empty.

We currently hold registration in all four states and have chosen not to publish the registration numbers on the site. Ask us and we will give you the number for your state, which you can then check against the issuing authority named below. If you would rather verify before speaking to us, each authority runs a public register you can search by business name.

State by state

New Jersey

New Jersey requires home improvement contractors to register with the Division of Consumer Affairs and to display the registration number in advertising. Plumbing work is separately reserved to licensed plumbers under the State Board of Examiners of Master Plumbers.

Status. Registered with the New Jersey Division of Consumer Affairs. Registration number available on request. 39 areas published.

Pennsylvania

Pennsylvania requires registration under the Home Improvement Consumer Protection Act, and the registration number must appear in advertising and on contracts. Plumbing licensing in Pennsylvania is handled locally rather than at state level, so requirements differ by municipality.

Status. Registered with the Pennsylvania Office of Attorney General. Registration number available on request. 17 areas published.

Connecticut

Connecticut requires Home Improvement Contractor registration with the Department of Consumer Protection, and the registration number must appear in advertising. Plumbing work is licensed separately by the state.

Status. Registered with the Connecticut Department of Consumer Protection. Registration number available on request. 19 areas published.

New York

New York licenses home improvement work at city and county level rather than statewide.

Work in the five boroughs requires a New York City Department of Consumer and Worker Protection Home Improvement Contractor licence. Nassau, Suffolk, Westchester, and Rockland counties each operate their own licensing. Plumbing is licensed separately in each jurisdiction.

Status. Licensed for home improvement work in each New York jurisdiction we publish. Licence numbers available on request. 38 areas published.

Sub-jurisdiction licences

  • New York City (DCWP). Registered with the New York City Department of Consumer and Worker Protection. Registration number available on request.
  • Nassau County. Registered with the Nassau County Office of Consumer Affairs. Registration number available on request.
  • Suffolk County. Registered with the Suffolk County Department of Labour, Licensing and Consumer Affairs. Registration number available on request.
  • Westchester County. Registered with the Westchester County Department of Consumer Protection. Registration number available on request.
  • Rockland County. Registered with the Rockland County Office of Consumer Protection. Registration number available on request.

Insurance

Insurance details are published here once recorded. Where a building or board requires a certificate naming it as additional insured, ask us before booking so the paperwork is in place ahead of the alteration approval.

Plumbing work

Plumbing is licensed separately from home improvement in every state we cover, and work on a main line is permitted in some municipalities and not others. Where a permit is required it generally has to be pulled by a licensed plumber. We confirm the position with the local authority for your address before scheduling rather than assuming it from a neighbouring town.

Well construction, casing repair, and pump work are a separate trade again, with their own licensing in each state. We install treatment downstream of the pressure tank and refer well work to a licensed well contractor.
