Working in Dronfield
We cover every part of Dronfield, including S18, and nearby Chesterfield (4.3 miles) and Sheffield (5.6 miles).
Being a smaller town does not change how we work in Dronfield: free survey, written quote, one team. For windowless bathrooms in Dronfield homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. If your Dronfield 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.
Most of Derbyshire 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
- 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
Decisions to make first
Wall or ceiling
A wall fan on an outside wall is the simplest. A ceiling fan over the shower takes steam away at source but needs ducting through the loft.
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.
