Why is being licensed important?
There are some “home service” companies (Housekeepers, lawn care, handyman services) out there who do their business on the side for extra income. These people may not be licensed with the state, which means they are not even legally set up to operate a business. If an accident or some kind of damage on the property, hiring an unlicensed contractor will cause major headaches in getting your home-owners insurance claims to cover it.
As a homeowner you should always insist on seeing documentation proving that the company is fully licensed, insured and bonded before you allow them into your home!
