Tips for Homeowners

Make sure the contractor you choose is licensed. It is a criminal offense to do home improvements without a license and there is no protection from the Guarantee Fund for the homeowner who uses an unlicensed contractor.
To find licensing status, call 410-230-6309 or 1-888-218-5925. Ask if complaints have been filed against a contractor and whether they have been resolved or are still open.
Request references from prospective contractor – check them!
Get a copy of the contractor’s current liability insurance certificate.
Always get a written contract.
Pay no more than 1/3 of the contract price as a down payment.
If a building, or any other type of, permit is needed ask to see it before work starts.
