Working in Welwyn Garden City
We cover every part of Welwyn Garden City, including AL7 and AL8, and nearby Hatfield (2.8 miles) and Hertford (5.5 miles).
In Welwyn Garden City, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If the only toilet in your Welwyn Garden City home is upstairs, a cloakroom under the stairs or in the utility can save a lot of trips. For a new cloakroom in Welwyn Garden City, the first thing we look at is where the nearest drain or soil stack runs.
Most of Hertfordshire has very hard water. 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
- Splashback or feature tiling and a new floor, often LVT or porcelain
- A concealed cistern frame or WC unit where the space allows
- A new waste connection to the soil stack or drain, or a macerator where the rules allow it
- Strip-out of the old fittings, waste removal and making good on the hall side
Decisions to make first
Door
An outward-opening door is usually needed so it does not hit the WC. A sliding door suits a narrow hallway where an outward door would block the way.
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.
