Using a power drill and paddle attachment mechanizes the job of stirring paint, but it can cause splatters. One way to solve the problem is to use a paper plate. Punch a hole in the center of the plate and push the end of the paddle attachment through the hole before chucking it into your drill. Then hold the plate down over the open can while stirring.
If the sewer line or drain line for a home you are buying crosses another property, make sure there is a recorded easement that will permit access to maintain or repair it. Without an easement, you would have to hope for your neighbor’s cooperation, but you would not be able to count on it.
