Trenchless Sewer Repair

We can repair your sewer line with little disruption to your landscaping! Trenchless pipe lining, also known as cured-in-place pipe (CIPP), works on existing damaged sewer pipes without the expense of excavation/destruction of property. We use a resin-saturated seamless felt liner that gets inverted throughout cracked or broken sewer pipe to create a new pipe within a pipe and extend its life by a minimum of 50 years.

Open Trench Sewer Repair or Replacement

Depending on the severity of the sewer line damage and where it is located, excavation may be the only effective solution for repairs. If a sewer line has a bad break, extensive erosion, severe offsets, significant bellies, or a completely collapsed line, you may need an open trench sewer repair or replacement. Our experienced crews will excavate and expose the pipe, replace the damaged sections, lay in new pipe, backfill a trench, and restore the landscape or pavement.

Horizontal Directional Digging/Directional Boring

  • Directional boring/horizontal directional drilling is an option to get utilities from one point over to another without destroying existing ground and obstacles that i
  • Horizontal directional drilling is a process above and beyond traditional trenching, working to connect utilities and services in places where traditional trenching seems impossible.
  • Directional boring is often used to create crossings under rivers, roadways, and existing structures. The purpose is to install pipes and conduits for transporting different types of fluids or materials.
  • The HDD technique has less construction and restoration cost of new water and wastewater pipes and for rehabilitation of failing pipes in urban areas where excavation is not required or impossible.

Video Camera Pipe Inspection

Assessing your home’s sewer system is a critical step in diagnosing your sewer pipes, preventing blockages, or identifying and busting through clogs or obstructions for a once-and-for-all fix.


Hydro-jetting is a non-invasive process involving high-pressure, jetted water to remove debris, clogging, and some roots to help clear the line. Once the flow is restored, the technicians can determine the cause of the backup and whether the piping would be a candidate for a new liner to remedy the issue permanently.

Root Cutting

If the root intrusion is severe, we will use a cable machine with various cutting attachments. The cable is fed down the line multiple times until all the roots are removed. Often we will use the cable machine in tandem with our hydro-jetting.


Over time rusty deposits will build up along the interior of old cast iron pipes. Like the barnacles found on the underside of a ship, the pipe scale will catch solids that can immediately cause drain blockage. We can descale your pipes with several different cutting tools to bring your old pipes back to life.

Storm Drain Cleaning

Storm drains and catch basins have been designed to prevent flooding by transporting rainwater to local waterways. Debris and litter will accumulate if not cleaned regularly, making these drains less effective.

Although Sewer cleanings can restore water flow, they are temporary. You will still have cracks or breaks in the line, and the roots will continue to grow back until you fix the underlying problem.  If you are looking for a permanent solution, the pipe will need to be repaired with a sewer liner or replaced conventionally with a brand new sewer pipe.

Trenchless pipe lining, sometimes known as cured-in-place-pipe (CIPP), is the process for rehabilitating existing, damaged sewer piping without the expense of excavation/destruction of property. We use a resin-saturated, seamless felt liner that gets inverted through cracked or broken sewer piping to create a new pipe within a pipe – thus extending its life by a minimum of approximately 50 years.
