Common questions
Does a contractor need to be registered in Connecticut?
Yes. Under the Home Improvement Act, a person may not hold themselves out as a home improvement contractor or salesperson without a certificate of registration from the Department of Consumer Protection. The Act excludes a contractor whose total home improvement contracts do not exceed $1,000 in 12 months, and exempts licensed trades for the work their licence covers.
What counts as home improvement?
The Act includes repair, remodeling, alteration and additions to a private residence, such as roofs, siding, windows, doors, decks, driveways, pools and storm restoration, where the total price exceeds $200. New home construction is separate.
What happens if my contractor is not registered?
Unregistered home improvement work is prohibited and generally a class B misdemeanor, and any violation of the Act is an unfair trade practice. A home improvement contract is also not valid or enforceable against an owner unless it meets the statute's requirements, including being entered into by a registered contractor or salesperson.
Is a registration an endorsement?
No. The statute prohibits contractors from representing that registration is an endorsement of their workmanship or competency by the commissioner. It means the contractor has registered with the state.
Why is there no phone number for contractors?
The state's credential data does not include phone numbers. We list the address the registrant gave DCP; contractors who claim their listing can add a phone number and description.
Is this site run by the state?
No. Connecticut Home Improvement Contractor Check is an independent directory compiled from the Department of Consumer Protection's open data. The official lookup is the Connecticut eLicense lookup at elicense.ct.gov.
