Important

Never hire a contractor who cannot provide a valid license number. A legitimate contractor will have no hesitation sharing their license credentials for you to verify independently. If a contractor refuses, discourages you from checking, or makes excuses, treat that as a serious red flag.

Visit the Maine Department of Professional and Financial Regulation website to verify any contractor's license before hiring.

Maine does not currently have reciprocal contractor licensing agreements with other states. Contractors licensed in other states must apply for a new Maine license through the standard application process. Some states may credit out-of-state experience toward licensing requirements -- contact the Maine Department of Professional and Financial Regulation for details.
