Common questions
What does a well contractor's license cover?
Most states license well work by class. Drilling and casing a new well usually takes a well driller's license, and installing or repairing the pump and pressure tank often takes a separate pump installer license. Each profile shows the class its roster lists, so match it to the job. Depth and geology drive most of the price of a new well; the well drilling cost guide breaks it down.
What do the septic license classes mean?
States and counties license septic roles separately. Installers build new and replacement systems, pumpers empty and clean tanks, and some places also license designers and inspectors. A pumping license usually doesn't cover installing a system, so check the class before you hire. For what a routine pump-out runs, see the septic tank pumping cost guide.
Who can inspect a septic system when I buy a home?
A few states, and some county programs, license septic inspectors as a class of their own, and profiles there show it. Elsewhere, whoever inspects holds another license, such as an installer's or a pumper's, so ask whether they open the tank and check the drainfield. Our guide to buying a home with a well or septic system covers what to book and when.
How often should a septic tank be pumped?
Every 3 to 5 years for a typical household; more often with a garbage disposal, a large family, or an undersized tank. Slow drains, sewage odors, gurgling pipes, or standing water over the drainfield mean the tank needs pumping, or the system needs repair, now.
Do I need a well and septic inspection when buying a house?
If the property is not on municipal water and sewer: yes, strongly recommended, and your lender may require them, so ask your loan officer. Well tests check flow rate and water quality; septic inspections check the tank, field lines, and permits. Schedule both early in your inspection period.
How do I check a contractor's license status?
Every profile on this site shows the license details its roster publishes, usually the license number, and links to the official source. Always confirm the license is active with the agency that issued it before signing a contract; we link you straight to the roster we sourced it from.
