CLEARMASTERS
Blocked drains and root removal
Inter-war clay drains and mature gardens mean roots are a common cause of blockages. We jet them clear, cut out roots and tell you whether the pipe needs repairing.
Learn moreBexleyheath is classic outer-London suburbia, with long streets of inter-war semis and bungalows, big back gardens and plenty of mature trees, around a busy shopping Broadway. Almost every home is on mains drainage, and much of our work here is clearing and surveying drains that have been in the ground since the 1930s.
Roots, cracked clay pipes and shifting joints in the London Clay are the usual suspects. Many homes have been extended at the back or into the loft, with new drains joined onto old ones. On the green-belt edge of the borough, towards Joydens Wood and the Cray valley, a few homes and farms still rely on septic tanks or cesspits.
Our crews work in south-east London most days and we answer the phone 24 hours a day, 365 days a year.

1930s drains

Questions answered
Bexleyheath drainage FAQs
What homeowners and businesses in Bexleyheath ask us most.
My 1930s semi’s drain keeps blocking. Why?
Original clay drains crack and shift over time, letting roots in. A CCTV survey will show whether a repair or lining is needed.
Should I survey the drains before an extension?
Yes. It shows where the drains run and their condition, which your builder and building control will need.
Can a drain be repaired without digging?
Often. Many cracked or root-damaged drains can be relined from inside. A survey shows whether that’s possible.
Do you empty grease traps on Bexleyheath Broadway?
Yes, for restaurants, cafés and takeaways.
Are there still septic tanks in Bexley?
A few, on the green-belt edges of the borough. We empty and service them.
