-
According to the FTC, get multiple estimates; a written estimate should include a description of the work, the materials, the completion date and the price; don't automatically choose the lowest bidder, and ask for an explanation if there's a big difference among them; consider only licensed and insured contractors, confirm the license with your state or county government and ask for proof of insurance.
-
According to the FTC, contract requirements vary by state; even if your state doesn't require a written agreement, ask for one; before signing, make sure it includes the contractor's name, address, phone number and license number, an estimated start and completion date, any promises made in conversations or calls about the scope of work and the cost of labor and materials, and a written statement of your right to cancel within three business days if you signed it at home or somewhere other than the seller's permanent place of business; and make sure all blank spaces are filled in.

-
According to the FTC, don't sign a document you haven't read, that's in a language you don't understand or that has blank spaces; if you talk with a salesperson or contractor in a language other than English, depending on where you live and what you're buying, you may be entitled to a copy of the contract in that language, so you can read and understand it before signing the English version; and don't let anyone pressure you into signing.
