Septic Tank Harford County | Johns Septic Service
John’s Septic Service is a family-owned and operated business that has served Harford County, Cecil County, and Baltimore County since 1969. It all began when the first John Call started the business with little more than a 1957 Dodge 1 ½ ton truck equipped with a homemade 1000-gallon steel tank and enough integrity and old-fashioned work ethic to fill it up many times over.
