Blocked drains, grease traps and pump stations in Redhill, and septic tanks and treatment plants in the villages around it, from a team just down the road.
Redhill is a busy railway town a short drive from our office in Smallfield. The town centre has restaurants, takeaways, offices and flats, and the streets around it range from Victorian terraces to large post-war and modern estates. Almost all of it is on mains drainage, so much of our work here is clearing and surveying drains and emptying grease traps.
Around the edges, it’s a different story. Villages and hamlets such as South Nutfield, Bletchingley, Outwood and the farms towards Salfords and Sidlow have homes on septic tanks, cesspits and treatment plants. Newer estates, including those around Merstham and Earlswood, sometimes depend on private pump stations.
The ground changes quickly here too: sandy greensand on the hills, heavy clay in the valleys. We work in Redhill most days and answer the phone 24 hours a day.
We clear blocked drains at homes, flats and businesses with high-pressure jetting, then survey them with a camera if the problem keeps coming back. Older terraces often share drains, and we’ll help you work out who’s responsible.

Redhill’s restaurants, cafés and takeaways need their grease traps emptied regularly to stop fat setting in the drains. We set up a schedule to suit how busy you are and leave a waste transfer note every time.

Hills, valleys and a busy town centre.
The hills around Redhill are sandy and drain well; the valleys are clay and drain slowly. Two homes a mile apart can have very different drainage.
Victorian terraces often share a drain run behind the houses. A blockage in a shared section is usually the water company’s, not yours.
With so many food outlets, fat is a common cause of blocked drains. Grease traps protect your drains and the sewer.
