Trenchless Sewer Repair Process

Trenchless Sewer Repair Process — What to Expect From Start to Finish

Most homeowners hear “sewer repair” and immediately think of digging up their yard, driveway, or landscaping.

The good news is — that’s no longer the only option.

Modern trenchless sewer repair follows a proven step-by-step process that allows damaged underground pipes to be restored with minimal disruption, faster timelines, and long-lasting results. At John Shelton Plumbing, we help homeowners throughout the Alle-Kiski Valley understand their options and complete sewer repairs without unnecessary excavation whenever possible.

What Trenchless Sewer Repair Means for Your Home

Trenchless sewer repair is a modern method of fixing damaged sewer lines without extensive digging. Instead of excavating the entire pipe, repairs are completed through small access points using specialized equipment and advanced trenchless technology.

For homeowners, this means:

• Less damage to landscaping and hardscaping
• Faster project completion
• Cleaner, less invasive repairs
• Reduced restoration costs
• Long-term pipe performance

Step 1: Sewer Camera Inspection

Every trenchless repair begins with a detailed sewer camera inspection. Using specialized video equipment, our technicians inspect the inside of the sewer line to identify the exact condition of the pipe.

During the inspection, we evaluate:

• Cracks and fractures
• Root intrusion
• Pipe corrosion
• Collapsed sections
• Grease buildup and blockages
• Overall pipe integrity

This step allows us to properly diagnose the issue and determine whether trenchless repair is the right solution.

Step 2: Cleaning and Pipe Preparation

Before the repair process can begin, the pipe must be thoroughly cleaned and prepared. This often involves hydro jetting or mechanical cleaning to remove debris and restore proper flow.

Preparation may include:

• Removing roots and obstructions
• Clearing grease and sludge buildup
• Restoring pipe flow
• Preparing the surface for lining adhesion

A properly cleaned pipe is critical for long-term trenchless repair success.

Step 3: Measuring and Planning the Repair

Once the sewer line is cleaned, our team measures the pipe and evaluates the severity of the damage to determine the best trenchless repair method.

This planning stage helps determine:

• The length and diameter of the pipe
• The location of damaged sections
• Whether pipe lining or pipe bursting is the better solution
• The best access points for the repair

Every sewer system is different, which is why a proper evaluation is essential before repairs begin.

Step 4: Installing the Liner or New Pipe

Depending on the condition of the existing sewer line, one of two trenchless methods is typically used:

Pipe Lining (CIPP)

Pipe lining creates a new pipe inside the old one using a flexible epoxy liner. Once inserted and inflated, the liner hardens into a seamless, durable new pipe.

Pipe Bursting

Pipe bursting breaks apart the old damaged pipe while simultaneously pulling a brand-new pipe into place underground.

Both methods avoid large-scale excavation while restoring the integrity of the sewer system.

Step 5: Curing and Finalizing the Repair

For cured-in-place pipe lining (CIPP), the new liner must be hardened — or cured — using heat, steam, or UV technology.

Once curing is complete:

• The new pipe becomes structurally sound
• Cracks and leaks are sealed
• The pipe interior becomes smooth and durable
• Flow performance is restored

The finished result is designed to provide reliable performance for decades.

Step 6: Final Inspection and Testing

After the trenchless repair is complete, a final sewer camera inspection is performed to confirm the success of the repair.

We verify:

• The pipe is fully restored
• Proper flow has been achieved
• The liner or replacement pipe was installed correctly
• No additional issues remain inside the system

This final testing ensures your plumbing system is operating exactly as it should before the project is completed.

Why Homeowners Choose Trenchless Sewer Repair

Trenchless sewer repair has become a preferred solution because it minimizes disruption while delivering long-term results.

• Protects landscaping and driveways
• Reduces excavation and restoration costs
• Speeds up repair timelines
• Provides durable, long-lasting pipe performance
• Offers a cleaner and more efficient repair process

In many cases, trenchless repairs can be completed in a fraction of the time required for traditional sewer excavation.
