CLEARMASTERS
Pump stations in new blocks
New residential and mixed-use buildings around Wembley Park rely on pump stations and sumps. We service them on a planned schedule, test pumps and alarms, and report to the managing agent.
Learn moreWembley is famous for the stadium and arena, and the area around them has been transformed with thousands of new flats, shops, restaurants and a designer outlet at Wembley Park. Those buildings depend on pump stations, plant rooms and grease traps that managing agents need to keep on top of, especially when tens of thousands of visitors arrive on event days.
Beyond the regeneration, Wembley, Alperton and Sudbury are streets of inter-war semis and terraces with old clay drains, and industrial estates along the North Circular and the River Brent need gullies and interceptors cleaned.
Our crews work in north-west London most days and we answer the phone 24 hours a day, 365 days a year.
