Contractors Are Not Licensed – Buyer Beware!

While there are a great many competent, ethical home contractors in Maine, it is up to you, the consumer, to find one. Home contractors are not licensed or regulated by the State of Maine. The old saying “Buyer Beware” applies. You should also keep in mind that the lack of state licensing allows the worst contractors to compete for your business alongside the best. The Attorney General’s Consumer Mediation Program ranks home contractors among the top three most complained about businesses every year.

We strongly recommend that you ask any contractor you are considering hiring for several references and that you follow up on them. It is also a good idea to check with your local building supply companies or real estate brokers. They will know the dependable contractors in your area.

Although home construction contractors are not licensed, some building trades are licensed. Plumbers, electricians, oil burner technicians, and installers of mobile and modular homes are licensed in Maine. For more information on these licensed trades, go to
