Septic and Excavation Services Across Rhode Island

Septic system installation, septic system repair and septic system design around North Kingstown and the rest of Rhode Island. We also repair sewer and water lines, clean drains and take on excavation, site work, drainage systems and retaining walls.

We handle septic system installation in Rhode Island and the septic system design that comes before it. When a system fails, we find the cause before the septic system repair begins. Our other services cover excavation, site work, sewer and water lines, drain cleaning, drainage systems and retaining walls. Call or text (401) 474-8926, and we look at the job and put the quote in writing.

  • Test holes dug within 25 feet of the planned leach field for the soil evaluation
  • Layouts sized by bedroom count and set back from wells and foundations
