Blocked Drain Barnet

Our base in Enfield means our Barnet engineers know the area's drainage like the back of their hand — which streets have older clay runs, which estates were built on the harder ground, where the council mains sit, and which gully designs are typical for which periods of housing.

That local knowledge translates into faster diagnoses, fewer surprises and lower bills. A drainage company that only knows central London learns your street on your time. We don't.

Root intrusion is the defining drainage problem across the Borough of Barnet. The mature oaks and horse chestnuts lining roads in Hadley Wood, Totteridge and Whetstone send roots into clay drain joints with remarkable persistence — we see the same pipes blocked again within two years when they are rodded rather than properly relined. Our engineers arrive in Barnet with CCTV kit as standard on any call-out that sounds like a recurring or slow-onset blockage, so we can confirm root involvement before recommending a fix.

Properties in High Barnet and New Barnet sold since 2015 often come with recent CCTV survey reports noting cracked clay runs. If you have one of these reports and the recommended remedial work was never carried out, now is the time — a small crack becomes a collapse under heavy rain. We offer no-dig patch relining and full CIPP lining as permanent fixes, both available same-day with pre-survey in the morning.
