Building Sewer Lateral Replacement & Compliance
Building sewer laterals extend from the home foundation across private property and public right-of-way to the city sewer main connection. Over time, older clay laterals can crack, allowing groundwater inflow or sewage leakage.
As licensed Class A General Engineering contractors (#1089561), Heise’s Plumbing handles street encroachment permits, utility coordination, trenchless pipe bursting, backwater valve installation, and final municipal inspector sign-offs.
