Working in Kirkby
We cover every part of Kirkby, including L32 and L33, and nearby Maghull (3.1 miles) and Litherland (4.4 miles).
In Kirkby, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. For windowless bathrooms in Kirkby homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. In Kirkby flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Most of Merseyside is supplied with soft water. Even so, condensation is the bigger problem in any bathroom, and a properly sized extractor is what deals with it. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
Decisions to make first
Replacement air
A fan needs air to replace what it removes, so leave a gap of around 10 mm under the door or fit a door grille. A sealed room starves the fan.
Axial, centrifugal or inline
Axial fans suit short, straight runs; centrifugal fans cope better with longer ducts; inline fans sit in the loft and are the quietest in the room.
Rules that apply in England
In England, Approved Document F sets bathroom extract at 15 l/s for an intermittent fan or 8 l/s for continuous extract. Wiring a new fan alters a circuit in a room with a bath or shower, so it is notifiable under Part P.
