Working in Feltham
We work right across Feltham — TW4, TW13 and TW14 — and in neighbouring Ashford and Hounslow.
In Feltham, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If you have bought a vanity unit for your Feltham bathroom, fit-only installation covers connecting the tap and waste and testing for leaks. We quote vanity unit work in Feltham after seeing the wall and pipework, so any re-tiling is on the quote from the start.
Supplies across most of Greater London are 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
- Isolation valves on the hot and cold supplies, so the tap can be changed later without draining the system
- A new tap, trap and the correct slotted or unslotted waste for the basin
- Patching or re-tiling the wall where the old basin left gaps
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.
Waste and overflow
A basin with an overflow takes a slotted waste; one without needs an unslotted waste, often a push-button 'click-clack' type.
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.
