Working in Northwich
We work right across Northwich — CW9 — and in neighbouring Winsford and Warrington.
Homes in and around Northwich vary, so we look at the floor, the walls and the water system before we price anything. Fans fitted in Northwich bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. If your Northwich bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
Supplies across most of Cheshire are moderately hard. 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
- A backdraught shutter and external grille, so cold air does not blow back in
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Making good around the fan and checking that it extracts properly at the grille
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.
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.
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.
