Connecticut's Official 
Home Improvement for Consumers
Getting any work done on your home requires hiring the right person to do the job. When considering a home improvement job, consumers should be prepared to talk with multiple contractors, ask for references, and ask about their experience completing the type of work you need done in your home. Find more information here about what to look for in a Home Improvement Contractor.
All Home Improvement Contractors, New Home Construction Contractors, and Home Improvement Salespeople must be registered with the Department of Consumer Protection (DCP).
Skilled work often done as part of a home improvement project (such as electrical, plumbing, HVAC) will likely require a more specific license that involves additional training and certification. Detailed information about what license may be needed for your project can be found here.
Be sure to verify licenses and registrations before you hire anyone by visiting www.elicense.ct.gov.
DCP enforces Connecticut’s Home Improvement Act, and administers the Home Improvement Guaranty Fund, which may provide assistance to homeowners who have a court judgement against a contractor who cannot pay them back for poor work. View the fact sheet and application to the Home Improvement Guaranty Fund.
If consumers have complaints regarding a Home Improvement Contractor, the best way to file with DCP is to fill out this complaint form, and email it along with any other helpful information such as contracts, receipts, permits, and accounts of your conversations with your contractor to dcp.complaints@ct.gov.
