Underground Repairs

Sewer Lines Repaired or Replaced

We are licensed and bonded in Trumbull and Mahoning counties to repair, replace, or install sanitary sewer lines. You may need your sewer lines replaced or repaired if you have broken or offset pipes, root infested pipes, sunken pipes, or just pipes that require drain cleaning too often. This repair will help prevent unsanitary sewer water backup.

Underground Downspout Lines

We install both 4-inch and 6-inch heavy-duty solid wall piping to conduct roof water away from the structure. Some water problems in your basement can be caused by faulty underground downspouts, which can discharge excessive water against your foundation.

Automatic and combination sewer valves

We install both automatic and manual sewer valves. The purpose of the valve is to prevent sewage water from reverting up your plumbing and entering your basement.
