Hiring a water well contractor in Jefferson County

Water well contractors drill and case new wells, install and service pumps and pressure tanks, and plug wells taken out of service. Well drilling cost is driven mostly by depth and geology. Most states license drilling and pump installation separately; confirm the license covers the work you need.

Before you sign anything: confirm the license on this page is still active with the agency that issued it, ask for proof of insurance, and get at least three written quotes; pricing on this work varies widely by site conditions.
