Working in Chelmsford
We work right across Chelmsford — CM1 — and in neighbouring Billericay and Witham.
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 has a concrete ground floor, a downstairs wet room may need the screed cut out to set the drain. We quote wet rooms in Chelmsford only after looking at the floor construction, because that is where most of the cost difference lies.
Supplies across most of Essex are very hard. If your supply in Chelmsford is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Strip-out, waste removal, a final flow test to the drain and handover
- A survey of the floor construction, the joist size and direction or the concrete slab, and the route to the soil stack
- A thermostatic shower valve, exposed or concealed, with heads to suit your water system
- A pre-formed floor former with a linear or centre drain, or a screed laid to fall
Decisions to make first
Floor tile
Matt or textured porcelain with good slip resistance. Mosaic gives extra grip on a centre-drain floor because of its many grout lines.
Open or screened
A fully open shower with no glass only works in a larger room, with the basin, WC and towels well away from the spray.
Rules that apply in England
In England, a new drain connection or changes at the soil stack can be building-regulations work under Part H, and new circuits or changes to the wiring in the room are notifiable under Part P. If the wet room is a newly formed bathroom, Approved Document F requires extract of 15 litres per second intermittent or 8 litres per second continuous.
