Working in Chelmsford
As well as Chelmsford itself (CM1), we survey in Billericay, Witham and Maldon.
Chelmsford is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. If your Chelmsford 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. In Chelmsford flats, the lease and the flat below are considered before a renovation is planned, particularly for moving the WC or adding a vent.
Water across much of Essex 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
- New hot and cold pipework and wastes, with isolation valves to each fitting
- Strip-out back to brick or studwork, with waste taken away by a licensed waste carrier
- Re-plastering or boarding, with cement-based boards and tanking in the wet areas
- New wiring, lighting, extractor fan and RCD protection, installed and certified by a qualified electrician
Decisions to make first
Heating
Moving the radiator, adding a heated towel rail or laying underfloor heating is simpler while the room is stripped.
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.
