CLEARMASTERS
Blocked drains and roots
We clear blocked drains with high-pressure jetting and cut out roots, then tell you whether the pipe needs a repair.
Learn moreTwickenham is mostly Victorian and Edwardian family homes, with riverside streets along the Thames, the River Crane winding through to the east, and a busy town centre of pubs and restaurants. It’s on mains drainage, so our work here is drains, surveys, pumps and grease traps.
Many homes have been extended at the back and into the loft, with new bathrooms joined onto old clay drains that crack and let roots in. Riverside properties and those near the Crane can be affected by high water, and some rely on pumps. Pubs and restaurants get very busy on match days and need their grease traps kept on top of.
Our crews work in south-west London most days and we answer the phone 24 hours a day, 365 days a year.

What we do for Twickenham customers
CCTV surveys for extensions and buyers
Before an extension or purchase, a CCTV survey shows where the drains run and their condition.

Grease traps for pubs and restaurants
Pubs and restaurants can be extremely busy on event days. We set a grease trap schedule that copes with the peaks and leave a waste transfer note every time.

Riverside and basement pumps
Homes by the river or with basements below the sewer rely on pumps. We service them and respond 24/7 if one fails.

Drainage in Twickenham: what to know
Edwardian homes between two rivers.
Extended homes
New bathrooms and extensions are often joined onto old clay drains. Survey before and after building work.
The Thames and the Crane
Low ground near both rivers can be affected by high water.
Busy days
Pubs and restaurants can see huge peaks in trade, so grease traps fill faster.

Questions answered
Twickenham drainage FAQs
What homeowners and businesses in Twickenham ask us most.
Should I survey my drains before a kitchen extension?
Yes. It shows where the drains run and whether they’re in good enough condition to build over or near.
My new bathroom drains slowly. Why?
It may have been connected to an old drain with a crack, sag or roots. A CCTV survey will show what’s happening.
Can roots be removed without digging?
Usually. We cut them out with specialist jetting heads, and many damaged pipes can be relined from inside.
Do pubs need their grease traps emptied more often on busy days?
They may. We can set a schedule that copes with peaks in trade.
Do you service riverside pumps?
Yes, with 24/7 cover if one fails.
