Working in Isleworth

In Isleworth we cover TW3, TW5 and TW7; we also cover Hounslow, 0.9 miles away, and Heston.

In Isleworth, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. For listed and period properties in Isleworth, we check early whether listed building consent applies to the work you have in mind. A renovation survey in Isleworth looks behind the surfaces, at joists, pipework and wiring, before any figure is put on paper.

Most of Greater London has very hard water. 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
A survey of the structure and services: joists, walls, ceilings, pipework, wastes, wiring and ventilation
New wiring, lighting, extractor fan and RCD protection, installed and certified by a qualified electrician
Strip-out back to brick or studwork, with waste taken away by a licensed waste carrier

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.

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.

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.

What problems are found when a bathroom is stripped out?

The usual ones are rotten floorboards or joists around the WC and bath, old lead or corroded pipework, joists notched too deeply for pipes, plaster that has come away from the wall and circuits without RCD protection. In homes built before 2000, asbestos can turn up in textured ceiling coatings, old floor tiles, cistern lids or boxing panels.
