Working in Maidenhead
We work right across Maidenhead — SL6 — and in neighbouring Marlow and Slough.
Homes in and around Maidenhead vary, so we look at the floor, the walls and the water system before we price anything. If your Maidenhead bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. We check the duct route at Maidenhead surveys, because a short, straight run to outside matters more than the fan's headline figure.
Most of Berkshire has 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
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Making good around the fan and checking that it extracts properly at the grille
- 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
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.
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.
