How listings are verified

The Septic Guide builds each state's directory from the septic license and certification lists that state agencies publish, such as the Texas Commission on Environmental Quality, the North Carolina Onsite Wastewater Contractors & Inspectors Certification Board and the Georgia Department of Public Health. A listing is marked licensed only when the person or business appears on that agency's list; the badge names the list. Services come from each business's own website or from the license type (a pumper license, for example).

Not every state licenses septic contractors: in 12 states counties or towns do it. See septic licensing by state and how we verify licenses.

Common questions

How do I find a licensed septic company near me?

Search your city, county or ZIP code above, or pick your state. The Septic Guide lists 28,538 septic companies and licensed septic professionals in 45 states. 27,059 of them are matched to a state septic license or certification list published by the issuing agency (data as of October 2026). Each license badge links to the agency's lookup so you can confirm it.

What does "licensed" mean in this directory?

A listing is marked licensed when the business or person appears on a state agency's published septic license or certification list. The badge names the agency and the license type. It is not a review of the work.

Why are some listings missing a phone number?

Some states publish only names and towns for license holders. Those listings stay in the directory because the license is verified; we add phone numbers as we match them to business records.
