Pump stations in riverside blocks, drains in Victorian terraces and grease traps for restaurants across Battersea and Nine Elms.
Battersea has changed enormously. Along the river, the regeneration around the old power station and Nine Elms has added thousands of flats in tall new buildings, many with basement plant rooms and pump stations that managing agents have to keep running. Inland, the streets around Northcote Road and Clapham Junction are long rows of Victorian terraces.
So our work here splits in two. In the new blocks, it’s planned maintenance of pump stations, grease traps for ground-floor restaurants, and drains that serve hundreds of homes. In the terraces, it’s blocked and broken drains, shared runs and CCTV surveys for buyers.
Our crews work in south London most days and we answer the phone 24 hours a day, 365 days a year.
New riverside buildings often have basement pump stations and sumps serving many flats. We service them on a planned schedule, test pumps, floats and alarms, clean the chambers and report to the managing agent.

Restaurants and cafés under new residential blocks need grease traps emptied regularly to keep the building’s drains clear. We set up a schedule and leave a waste transfer note every time.

We clear blocked drains in the terraces around Northcote Road, Lavender Hill and Clapham Junction with high-pressure jetting and tell you what caused them.

New towers by the river, old terraces inland.
Large blocks depend on pumps and sumps. Planned maintenance avoids breakdowns that affect every resident.
Fat from ground-floor kitchens can block a building’s drains. Grease traps protect everyone upstairs.
Old clay drains in the terraces crack and let roots in. Repeated blockages are worth a survey.

★★★★★Very professional operation. Super clean tanker. Responded quickly to quote and booking requests. Arrived on time. Kept us notified throughout. Very pleasant and helpful guy operating the equipment. Gave sound advice with ongoing maintenance tips. Will definitely be saving Clearmasters' contact details to use them again.
★★★★★Clearmasters have emptied our Septic Tank for many years. It is not an easy placed tank to get to but the chaps manage perfectly. I find them very efficient, friendly and polite. Thank you Valerie Wise

Questions answered
What managing agents, restaurants and homeowners in Battersea ask us most.
Yes. We service pump stations and sumps in residential and mixed-use buildings on a planned schedule and report to the managing agent after every visit.
The restaurant should have a working grease trap that’s emptied regularly. We can survey the drain to show where the fat is coming from.
It’s worth it. Old clay drains often hide cracks or roots, and a survey costs far less than a repair.
Shared drains are usually the water company’s. The section serving only your house is usually yours.
