Emergency plumber in Lewisham

Brockley's big Victorian houses were often divided into three or four flats, with bathrooms added on landings and over other rooms. They share supply pipes and soil stacks, and the cellar or lower ground flat is first to suffer when a stack or drain blocks. Leaks from upper bathrooms come through tall ceilings below. Stop taps can be in cellars, under hall floors or under the kitchen sink of the ground floor flat.

If you are a leaseholder, tell the freeholder or managing agent about any leak from a shared pipe or another flat. The Leasehold Advisory Service says the freeholder is usually responsible for communal pipes and tanks, and each leaseholder for pipes and appliances serving their own flat.

In whole houses, the common emergencies are frozen and burst pipes in lofts and under suspended floors after cold nights, leaking supply pipes under the front garden, and blocked drains in back gardens. Forest Hill has hilly streets, and Thames Water notes that customers at the top of a hill can take longer to get full pressure back after a supply interruption. If you have no water after a burst main and your neighbours do, it may be an airlock, and Thames Water asks you to call it.

In the cold snap of January 2026, Thames Water said pipes in unheated lofts, garages, utility rooms and along cold outside walls were the most at risk. Many Lewisham houses have pipes in exactly those places, plus outside taps on back walls. Lag what you can, turn off and drain outside taps before winter, and know where your stop tap is so you can shut it the moment a pipe splits.

If you are a tenant, your landlord must keep the water installations in repair under section 11 of the Landlord and Tenant Act 1985, so report frost damage straight away in writing.

In New Cross, Deptford and across Lewisham's estates, communal pipes and pumps are the housing provider's or freeholder's. Report leaks and loss of water to the repairs line. Isolate your own supply at your stop tap and switch off electrics near any water while you wait.
