Working in Sandbach
In Sandbach we cover CW11; we also cover Crewe, 4.6 miles away, and Congleton.
Being a smaller town does not change how we work in Sandbach: free survey, written quote, one team. If your Sandbach 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. In Sandbach flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Most of Cheshire has moderately hard water. Scale is a minor issue next to condensation, which is what a properly sized extractor fan is for. 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
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- A backdraught shutter and external grille, so cold air does not blow back in
Decisions to make first
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.
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.
