Working in Witham
In Witham we cover CM8; we also cover Maldon, 5 miles away, and Braintree.
Homes in and around Witham vary, so we look at the floor, the walls and the water system before we price anything. If your Witham home is listed or in a period terrace, a fan ducted through the loft to a roof vent can avoid a new hole in the front wall, though consent may still apply. We check the duct route at Witham surveys, because a short, straight run to outside matters more than the fan's headline figure.
Most of Essex has very hard water. Steam carries that scale onto mirrors and glass, so a fan that clears the room quickly helps on both counts. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A backdraught shutter and external grille, so cold air does not blow back in
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- A check of the room, any existing fan or vent, and the shortest route to the outside
Decisions to make first
Noise
Compare the stated noise level in decibels. Inline fans and low-speed continuous fans are much quieter in the room than budget axial fans.
Timer or humidistat
A timer keeps the fan running after the light goes off. A humidistat starts it whenever moisture rises, which suits rooms where people forget.
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.
