Watch out for high pressure sales tactics and prices that seem "too good to be true."
Know your contractor, check references, and check the Better Business Bureau.
Look at completed job (workmanship) and ask for proof of insurance.
Do not sign a contract that has blank spaces or anything that you do not understand.
Find out whether the contractor guarantees his or her work and products.
Get lien waivers. This protects you or your property in the event a general contractor fails to pay subcontractors or materials suppliers.
Don't make final payment until you are satisfied and all required inspections have passed.
Remember, you have 3 business days to cancel any contract if the sale is made and signed at your home. The contractor cannot take this right away from you by initiating work, selling your contract to a lender, or any other tactic.
Inspecting Your Contract
Inspect your contract carefully. Make sure it includes
The contractor's full name, address and telephone number
A detailed description of the work to be performed
Starting and estimated completion dates
Total cost of work including charges for estimates or changes
Schedule and method of payment including down payment, subsequent payments and final payment
