Signs of a Collapsed Drain: Complete Guide

A collapsed drain can cause thousands of pounds of damage if left undetected. The early warning signs are often subtle and easy to dismiss, but catching a collapse early dramatically reduces repair costs and prevents secondary damage to your property. This guide covers every sign to watch for and what to do if you suspect a collapse.

What to Look For

• Slow drainage across multiple fixtures simultaneously
• Foul sewage smells that won't go away with cleaning
• Damp patches on ground-floor walls or floors
• Sinkholes or depressions in the garden or driveway
• Recurring blockages that keep returning after clearing
• Cracks in walls or foundations near drain runs

How We Diagnose the Problem

The only way to confirm a collapsed drain is with a CCTV survey. The camera travels through the pipe and shows exactly where and how badly the collapse has occurred. We assess whether it's a partial collapse (potentially repairable with relining) or a full collapse (requiring excavation).

How We Fix It

Early detection means more repair options and lower costs. Partial collapses caught early can often be fixed with no-dig relining. Full collapses require excavation but are less extensive when caught before secondary damage occurs. All repairs include CCTV verification and guarantees.
