Verified record
Derek B Murphy is an electrician working out of Pepperell, and 21 building permits sit under his name on BuildZoom — steady permitted electrical work rather than a one-off sideline. BuildZoom lists a Massachusetts electrician licence, #22700, for him. A straightforward call for residential electrical work in the Pepperell area. Look that licence number up on the state's register to see where it stands, ask for a certificate of insurance, and get the scope and price in writing before the work starts.
