Working in Welling
As well as Welling itself (DA6, DA15 and DA16), we survey in Bexley, Eltham and Thamesmead.
London homes in Welling often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. In Welling flats, the lease and the flat below are considered before a renovation is planned, particularly for moving the WC or adding a vent. If you have just bought a house in Welling, renovating the bathroom before moving in saves living through the dust.
Water across much of Greater London is very hard. We plan easy-clean glass, rimless toilets and finishes that do not show limescale. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- New wiring, lighting, extractor fan and RCD protection, installed and certified by a qualified electrician
- New hot and cold pipework and wastes, with isolation valves to each fitting
- A survey of the structure and services: joists, walls, ceilings, pipework, wastes, wiring and ventilation
- Layout changes such as moved doors, new stud walls or boxing for concealed cisterns
Decisions to make first
Pipe material
Copper suits exposed runs and the area near the boiler. Plastic pipe is quicker under floors and inside walls, and long runs need fewer joints.
Heating
Moving the radiator, adding a heated towel rail or laying underfloor heating is simpler while the room is stripped.
Rules that apply in England
In England, structural changes, new drainage or a new connection to the soil stack under Part H, and new circuits under Part P can all be building regulations work. A registered electrician can self-certify the electrics; structural and drainage work may need a building notice or a full plans application to building control.
