Finding out your sewer line needs repair is rarely welcome news. The right method for your situation depends on the extent of the damage, the condition of your pipes, and what’s sitting above them. Here’s a breakdown of the most common sewer line repair approaches.

Traditional Excavation

The traditional method involves digging up the ground above the damaged pipe to access, repair, or replace it.

Pros:

• Works on any damage
• Full pipe access
• Well-established process

Cons:

• Highly disruptive to property
• Longer completion time
• Costly cleanup and restoration

Excavation requires heavy equipment and can mean tearing up landscaping, driveways, patios, or even sections of road, depending on where the line runs. Restoration costs can add significantly to the total bill. Water also has to be shut off for the duration of the work.

Pipe Lining (Cured-in-Place)

Pipe lining, often called cured-in-place pipe (CIPP), is a trenchless technique where plumbers insert a flexible, epoxy-coated liner into the existing pipe. Once inflated and cured, it hardens into a smooth new pipe within the old one.

Pros:

• Minimal yard disruption
• Resists root intrusion
• Often completed the same day

Cons:

• Reduces pipe diameter slightly
• Requires intact host pipe
• Not suitable for collapsed pipes

Pipe lining is a strong option when the existing pipe still has structural integrity but has cracks, corrosion, or early root intrusion. It’s faster and far less disruptive than digging, and the materials used are built to last.

Pipe Bursting

Instead of lining the old pipe, pipe bursting replaces it entirely. A hydraulic tool is pulled through the existing pipe, breaking it apart as a new pipe is laid in its place.

Pros:

• Full pipe replacement
• No excavation needed
• Durable, modern materials

Cons:

• Higher upfront cost
• Needs small access points
• Not ideal for all pipe layouts

Pipe bursting is a good fit when the old pipe is too deteriorated for lining but you still want to avoid the disruption of traditional digging. It’s especially valuable when the sewer line runs beneath landscaping, a driveway, or other features you’d rather not disturb.

Which Method Is Right for You?

Trenchless methods, like lining and bursting, require the pipe to be accessible and at least partially intact. A collapsed or badly misaligned line often requires traditional excavation. If your sewer line runs under a newly paved driveway or mature landscaping, the cost of surface restoration with traditional methods can tip the scales toward a trenchless approach.

Trenchless repairs can carry higher upfront costs, but when you factor out excavation, labor, and restoration expenses, the total is often comparable or even lower.
