Working in Finchley
In Finchley we cover N2, N3 and N12; we also cover Muswell Hill, 2.4 miles away, and Cricklewood.
In Finchley, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. A renovation survey in Finchley looks behind the surfaces, at joists, pipework and wiring, before any figure is put on paper. If your Finchley 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.
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
- Re-plastering or boarding, with cement-based boards and tanking in the wet areas
- Layout changes such as moved doors, new stud walls or boxing for concealed cisterns
- New hot and cold pipework and wastes, with isolation valves to each fitting
- Repairs to rotten floorboards, joists or other timber found once the room is open
Decisions to make first
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.
Shower floor
With the floor already up, a renovation is the easiest time to form a level shower floor or a full wet room.
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.
