Drain Relining vs Excavation

When a drain needs repairing, the two main options are no-dig relining and traditional excavation. Both are effective, but they suit different situations. Understanding the pros and cons of each helps you make an informed decision — and potentially save thousands.

What to Look For

• Relining: no digging, faster, less expensive for suitable pipes
• Excavation: necessary for fully collapsed or severely damaged pipes
• Relining suits cracks, displaced joints, root damage, partial collapse
• Excavation suits full collapse, crushed pipes, gradient correction
• Relining: typically £800–£3,000 for residential jobs
• Excavation: typically £1,500–£10,000+ depending on depth and location

How We Diagnose the Problem

A CCTV survey determines which method is appropriate. We assess pipe condition, diameter, access, and the type of damage to recommend the most cost-effective solution. In some cases, a combination of both methods is the best approach.

How We Fix It

We always recommend the least disruptive, most cost-effective option. If relining is suitable, we use it. If excavation is necessary, we keep it targeted. Many jobs use relining for most of the pipe run with a short excavation for the worst section.
