Working in Harrow
As well as Harrow itself (HA1, HA2, HA3 and 2 more postcode districts), we survey in Brent, Wembley and Northolt.
London homes in Harrow often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. Whether your Harrow bathroom needs a refresh or a full strip back to brick, the written quote shows both where both are realistic. A renovation survey in Harrow looks behind the surfaces, at joists, pipework and wiring, before any figure is put on paper.
Supplies across most of Greater London are 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
- New wiring, lighting, extractor fan and RCD protection, installed and certified by a qualified electrician
- 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
- Tiling, fitting of the suite and furniture, making good and decorating, then handover
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.
