Working in Farnham
We work right across Farnham — GU9 and GU10 — and in neighbouring Aldershot and Fleet.
In Farnham, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. In Farnham flats, the lease and the flat below are considered before a renovation is planned, particularly for moving the WC or adding a vent. A renovation survey in Farnham looks behind the surfaces, at joists, pipework and wiring, before any figure is put on paper.
Water across much of Surrey 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
- A survey of the structure and services: joists, walls, ceilings, pipework, wastes, wiring and ventilation
- New hot and cold pipework and wastes, with isolation valves to each fitting
- Layout changes such as moved doors, new stud walls or boxing for concealed cisterns
- Re-plastering or boarding, with cement-based boards and tanking in the wet areas
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.
Plaster or boards
Plaster suits dry walls that will be painted. Cement-based tile backer boards are the better base behind showers and under heavy tiles.
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.
