Working in Staines
In Staines we cover TW15, TW16, TW17 and 1 more postcode districts; we also cover Egham, 2 miles away, and Ashford.
Homes in and around Staines vary, so we look at the floor, the walls and the water system before we price anything. Where your Staines home already has a WC on gravity drainage, a macerator opens up more places a new cloakroom can go. If you are refreshing a dated cloakroom in Staines, a wall-hung WC and slim vanity can change the room in a few days.
Supplies across most of Surrey are hard. Taps, plug wastes and toilet pans scale up quickly, so chrome copes better than matt black, and a removable aerator is worth having. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Strip-out of the old fittings, waste removal and making good on the hall side
- A new waste connection to the soil stack or drain, or a macerator where the rules allow it
- Lighting wired by a qualified electrician, tested and certified
- An extractor fan ducted to outside, wired with an overrun timer or linked to the light
Decisions to make first
Macerator or gravity
Gravity drainage is silent and needs no maintenance. A macerator lets a WC go where a pipe could not otherwise fall, provided another WC in the house is on gravity drainage.
Finishes
A small room can carry a bolder tile or wallpaper. A feature wall behind the WC costs far less here than in a full bathroom because there is so little of it.
Rules that apply in England
In England, a new WC connected to the soil stack or drain is drainage work under Part H, and a newly formed cloakroom without an opening window should have mechanical extract; Approved Document F gives 6 litres per second as the design rate for a WC, against 15 for a bathroom. Because a cloakroom has no bath or shower, adding a light to an existing circuit is not notifiable under Part P, but a new circuit is.
