Working in Sunbury-on-Thames
We work right across Sunbury-on-Thames — KT12, TW16 and TW17 — and in neighbouring Walton-on-Thames and West Molesey.
In Sunbury-on-Thames, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Sunbury-on-Thames home is older and the bathroom still has original pipework or plaster behind the tiles, the survey shows whether a renovation or a refit makes more sense. If you have just bought a house in Sunbury-on-Thames, renovating the bathroom before moving in saves living through the dust.
Supplies across most of Surrey are 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
- Strip-out back to brick or studwork, with waste taken away by a licensed waste carrier
- Tiling, fitting of the suite and furniture, making good and decorating, then handover
- Repairs to rotten floorboards, joists or other timber found once the room is open
- Re-plastering or boarding, with cement-based boards and tanking in the wet areas
Decisions to make first
How far back to strip
Back to brick gives a clean start. Keeping sound plaster on some walls saves time and money, and the survey shows which walls can stay.
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.
