Know The Requirements
Do your homework regarding your contractor's licensing. All states
that license contractors and tradesmen keep lists of license holders.
Contact your state licensing board for licensing requirements specific
to your state. Except for plumbers and electricians, tradesmen paid
by the hour usually don't |
| need a license. Contractors bidding on
any significant work (more than a few hundred dollars) need a license
in most states. If you have a problem with a licensed contractor or
tradesman, the state licensing board can be a powerful ally in resolving
issues. Get into a dispute with an unlicensed contractor or tradesman
and you're on your own. |

on a bid or contract does not necessarily mean the license is valid.
Before you sign anything, call your state licensing board to make
sure the contractor is properly licensed in the class of work to be
performed, and that the license is in good standing. |
