CLEARMASTERS
Grease traps for riverside restaurants and bars
Kingston’s riverside and town centre have dozens of restaurants and bars. We empty grease traps on a schedule that suits your trade and leave a waste transfer note every time.
Learn moreKingston is a busy riverside town with one of outer London’s biggest shopping centres, a university, a riverside full of restaurants and bars, and streets of Victorian and inter-war homes stretching out to Surbiton, Norbiton and New Malden. It’s on mains drainage, so our work here is grease traps, drains and pumps.
The Thames and the Hogsmill both run through the borough. Riverside flats and low-lying homes can be affected by high river levels, and some rely on pumps to reach the sewer. Restaurants along the riverside and in the town centre need grease traps emptied, and the student population means plenty of blocked drains in shared houses.
Our crews work in south-west London most days and we answer the phone 24 hours a day, 365 days a year.
