Check for qualifications, like licensing
Many states, but not all, require contractors to be licensed and/or bonded. Check with your local building department or consumer protection agency to find out about licensing requirements in your area. Licensing can range from simple registration to a detailed qualification process. If your state or locality has licensing laws, make sure the contractor’s license is current.

Look at sites you trust that post ratings and reviews
Do people seem to have similar experiences, good or bad? You also can check out a contractor’s online reputation by searching for the company’s name with words like “scam,” “rip-off,” or “complaint.”
Ask Questions
How many projects like mine have you completed in the last year?
Ask for a list so you can see how familiar the contractor is with your type of project.
Will my project require a permit?
Most states and localities require permits for building projects, even for simple jobs like decks. A competent contractor will get all the necessary permits before starting work on your project. You may want to choose a contractor familiar with the permitting process in your county, city, or town.
May I have a list of references?
A contractor should be able to give you names, addresses, and phone numbers of at least three clients with projects like yours. Ask each client how long ago the project was and whether it was completed on time.
