Can Tree Roots Block Drains?

Yes — tree roots are one of the most common causes of blocked drains in the UK. Roots naturally seek out moisture, and the joints and cracks in drain pipes provide entry points. Once inside, roots grow rapidly in the nutrient-rich environment, eventually filling the entire pipe bore and causing complete blockages.

What to Look For

• Willows, poplars and oaks are the most aggressive root producers
• Roots can travel 10–20 metres from the tree trunk
• Old clay pipes with mortar joints are most vulnerable
• Modern plastic pipes with rubber ring joints are more resistant
• Root blockages often worsen in spring and autumn during growth periods
• Recurring blockages at the same point often indicate root ingress

How We Diagnose the Problem

CCTV drain surveys clearly show root ingress — from fine hair roots at early stages to massive root balls that completely fill the pipe. We identify which joints or cracks the roots are entering through and assess whether they've caused structural damage beyond blocking.

How We Fix It

We remove roots with mechanical cutting and high-pressure jetting, then reline the pipe to seal all entry points permanently. The seamless liner creates a root-proof barrier. For trees in close proximity to drains, we recommend annual CCTV checks to catch regrowth early.
