Drains cleared and surveyed in Banstead and its neighbours, and septic tanks and treatment plants looked after across the villages of the Downs.
Banstead sits high on the chalk of the North Downs, with Banstead Downs and Epsom Downs on either side and a string of leafy villages around it: Tadworth, Kingswood, Walton on the Hill, Burgh Heath and Chipstead. Most homes are on mains drainage, often on generous plots with long private drain runs and plenty of mature trees.
Those long drains and big trees keep us busy. Roots get into older pipes, and a blockage halfway down a 40-metre drive is a very different job from one under a terrace. Some of the larger houses and the more scattered homes around Walton Heath and the Chipstead valley are on septic tanks or treatment plants.
The chalk drains well, but it also feeds the groundwater that supplies drinking water, so private systems need to work properly here. We’re a short drive from Banstead and answer the phone 24 hours a day.
Large gardens and mature trees mean roots are the most common cause of blocked drains around Banstead. We clear blockages with high-pressure jetting, cut out roots, and tell you whether the pipe needs repairing.

Big plots often mean long private drain runs, sometimes with chambers buried under lawns or drives. A CCTV survey traces the route, shows the condition of every section and pinpoints where any defects are.
