Drains, basement pumps and grease traps looked after for flats, houses and restaurants in Notting Hill and Ladbroke Grove.
Notting Hill’s tall stucco terraces and Victorian villas were built as single houses, but many are now split into four or five flats, with a basement or lower-ground flat at the bottom. That means shared drains, shared responsibility and, very often, a pump in the basement that everyone above relies on without knowing it.
Around Portobello Road, Westbourne Grove and Ladbroke Grove, restaurants, cafés and bars need grease traps emptied, and market traders and shops have drains that take a lot of punishment. Communal garden squares add tree roots to the mix.
Our crews work in London most days and we answer the phone 24 hours a day, 365 days a year.
When a drain blocks in a converted house, the lower-ground flat usually finds out first. We clear it with high-pressure jetting, find out which flat or section caused it, and give you the information to sort it out with neighbours or the freeholder.

A CCTV survey shows the condition of the drains you share responsibility for, with a written report you can pass to the freeholder, agent or a buyer.

Lower-ground flats below the sewer depend on a pump. We service them, test the floats and alarms, and come out 24/7 if one fails.

Restaurants, cafés and bars need grease traps emptied regularly. We set up a schedule and leave a waste transfer note every time.

Big old houses split into flats.
In converted houses, the drain is often shared between flats. Your lease should say how repairs are split.
If your flat is below street level, it may rely on a pump. Find out where it is and when it was last serviced.
Mature trees in communal gardens send roots a long way. Repeat blockages are often roots.

Questions answered
What flat owners, freeholders and businesses in Notting Hill ask us most.
It depends on your lease. Usually the freeholder arranges repairs to shared drains within the building and costs are shared. Drains shared with neighbouring buildings are usually the water company’s.
It’s the lowest point, so when a drain blocks, waste backs up there first. If it relies on a pump and the pump fails, it floods too.
If your toilet or drains are below the level of the sewer in the street, almost certainly. We can find it and check it over.
Yes. Roots travel a long way to find water and get in through cracks and joints. A CCTV survey will show if that’s happening.
Yes. We empty grease traps for restaurants, cafés and bars across Notting Hill.
