Working in Windsor

We work right across Windsor — SL4 — and in neighbouring Slough and Egham.

Homes in and around Windsor vary, so we look at the floor, the walls and the water system before we price anything. For listed and period properties in Windsor, we check early whether listed building consent applies to the work you have in mind. If you have just bought a house in Windsor, renovating the bathroom before moving in saves living through the dust.

Water across much of Berkshire is 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
Re-plastering or boarding, with cement-based boards and tanking in the wet areas
A survey of the structure and services: joists, walls, ceilings, pipework, wastes, wiring and ventilation
Repairs to rotten floorboards, joists or other timber found once the room is open

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.

Combining rooms

Taking out the wall between a bathroom and a separate WC gives one larger room, but it is structural work and may need building control.

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.
