A homeowner in Arkansas doesn’t need a license to do the work himself or herself. However, a contractor (if used) must be licensed if the work, including labor and material, exceeds $2,000.00. Subcontractors working for a licensed contractor do not need their own license. However, if the general contractor is not licensed, then the subcontractor does need their own license.
The Federal Government does not regulate licensing for plumbers; they are on a state-by-state government level. Most states have some sort of licensing requirement for plumbers and any general contractors. However, if plumbers aren’t licensed, they could be subjected to expensive fines and it could result in the loss of their being allowed to practice their trade.
Another way to avoid a service call from your plumber is to make sure the outside faucets are turned off in the winter and make sure you disconnect the outside hoses. You need to shut the water off from the inside. Then, open the valve on the outside to let the water that’s in there drain out—you switch both of them to the opposite direction so one is always closed and one is always open. We have to fix tons of these in the spring mostly because people leave their outside hoses connected and they freeze up. The repair could cost $100-$200 or more. Another tip would be if you’re going away for any length of time, like on vacation, turn off your water. If on any of those days the temperature drops below freezing, have someone check in on your house. I’ve been called to homes where the family returned from vacation, and there was water flooding out from the front door.
