Mauldin’s Well Service is based in Friday Harbor, in San Juan County. This listing comes from Washington State license records; no company website was found, so it does not list specific services or a service area beyond the office county. Ecology’s driller search lists one water well operator at the company. L&I lists plumbing (pump and irrigation) and electrical (pump and irrigation) registrations.
Ask the company directly which services it offers and where it works. Before hiring any well contractor, check its current Ecology and L&I license status using the links in the sources.
