Working in Doncaster
We work right across Doncaster — DN1, DN2 and DN4 — and in neighbouring Bentley and Adwick le Street.
Doncaster is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. We check the duct route at Doncaster surveys, because a short, straight run to outside matters more than the fan's headline figure. If your Doncaster bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
Most of South Yorkshire 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
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- 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
- A check of the room, any existing fan or vent, and the shortest route to the outside
Decisions to make first
Intermittent or continuous
An intermittent fan runs during and after use. A continuous fan runs quietly all the time at a low rate and boosts when humidity rises.
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.
