Working in Thamesmead
We work right across Thamesmead — DA18, SE2 and SE28 — and in neighbouring Barking and Welling.
In Thamesmead, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. Landlords in Thamesmead can have a worn basin replaced with a vanity unit in half a day to a day. If your Thamesmead water is hard, a tap with a removable aerator and a smooth one-piece basin top are easier to keep clean.
Water across much of Greater London is very hard. Taps, plug wastes and toilet pans scale up quickly, so chrome copes better than matt black, and a removable aerator is worth having. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Fitting the unit level, with the basin sealed to the top and the top sealed to the wall
- Moving the waste and supply positions where the new unit needs them higher, lower or to one side
- Isolation valves on the hot and cold supplies, so the tap can be changed later without draining the system
- Testing for leaks and checking the trap holds its seal
Decisions to make first
Basin type
An inset or semi-recessed basin, a one-piece moulded top, or a countertop basin on a worktop. Countertop basins need a tall tap or a wall-mounted one.
One basin or two
Two basins help a busy household if the wall is long enough. In a smaller room, one basin with a longer top often works better.
Rules that apply in England
In England, the tap and supply pipework come under the Water Supply (Water Fittings) Regulations 1999. A new waste connection to the soil stack can be Part H work, and adding a light to the unit or above it is notifiable under Part P.
