CLEARMASTERS
Interceptors at warehouses and depots
Distribution warehouses, depots and retail parks need interceptors emptied and gullies cleaned. We provide waste transfer notes for every load and can set up a planned schedule.
Learn moreEdmonton sits in the Lea valley in the south-east of Enfield, with large industrial estates, distribution warehouses and retail parks along the river and the North Circular. Behind them are streets of terraces and inter-war houses, and busy shopping centres at Edmonton Green and Angel Edmonton.
Industrial and distribution sites need interceptors and gullies cleaned regularly. Pymmes Brook and Salmons Brook cross the area, and low-lying streets near them have flooded in the past. In the terraces, old drains block and crack, and takeaways need grease traps emptied.
We’re SafeContractor, Achilles UVDB and RISQS approved, our crews work in north London most days, and we answer the phone 24 hours a day.

What we do for Edmonton customers
Blocked drains in homes and shops
We clear blocked drains in terraces, flats and shops with high-pressure jetting and survey them with CCTV when they keep coming back.

Flood water removal
When heavy rain floods a basement, yard, car park or chamber near the brooks, our tankers pump it out and take it away.

Grease traps and pumps
Takeaways and restaurants need grease traps emptied; some sites rely on pumps. We handle both, with 24/7 cover.
