Working in Northallerton
We work right across Northallerton — DL6 and DL7 — and in neighbouring Yarm and Darlington.
Northallerton gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Northallerton 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 Northallerton surveys, because a short, straight run to outside matters more than the fan's headline figure.
Water across much of North Yorkshire is 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 fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- A backdraught shutter and external grille, so cold air does not blow back in
- 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.
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.
