If you hire a licensed contractor in Maryland, you are protected by the State's Home Improvement Guaranty Fund. This fund is administered by the Home Improvement Commission to compensate homeowners who suffer economic damages at the hands of a licensed home improvement contractor. No coverage is provided to the homeowner if the contractor is not properly licensed.

Licensed contractors in Maryland must provide proof of financial solvency based on the scope and size of their business in relation to total assets, liabilities, credit rating, and net worth.

The BuildZoom score is based on a number of factors including the contractor's license status, insurance status, verified work history, standing with local consumer interest groups, verified reviews from other BuildZoom users and self-reported feedback from the contractor.

When it comes to major construction work or even minor alterations to your home, hiring the wrong contractor could result in incomplete or defective work. You may even find yourself dealing with huge liability claims. BuildZoom does the homework for you and helps you hire the right contractor.

The Maryland Home Improvement Commission recommends getting at least three written bids before hiring a contractor. Do not automatically accept the lowest bid - an abnormally low bid may indicate the contractor made a mistake and is not including the same work quoted by their competitors.
