Signs of a Collapsed Drain

A collapsed drain can go undetected for weeks or even months, causing increasing damage to your property. Knowing the warning signs helps you act quickly and avoid costly repairs. Here's what to look for and when to call a drainage engineer.

What to Look For

• Slow-draining sinks, baths or toilets across the property
• Foul sewage smells inside or outside your home
• Damp patches on walls, floors or ceilings
• Sinkholes or depressions in the garden or driveway
• Recurring blockages that keep coming back after clearing
• Cracks appearing in walls or foundations
• Rat or insect activity near drains
• Unusually lush patches of grass over drain runs

How We Diagnose the Problem

Our engineers use CCTV drain surveys to inspect the interior of your pipes and identify the exact location and severity of any collapse. The camera shows whether the pipe has partially or fully collapsed, and reveals the cause — whether it's root ingress, ground movement, or age-related deterioration.

How We Fix It

Depending on the severity, we repair collapsed drains using no-dig relining for partial collapses or full excavation and pipe replacement for complete failures. All work includes a final CCTV check and comes with an insurance-backed guarantee.
