Working in Chertsey
As well as Chertsey itself (KT15, KT16 and TW17), we survey in Weybridge, Staines and Egham.
Being a smaller town does not change how we work in Chertsey: free survey, written quote, one team. If your Chertsey bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. If your Chertsey 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 Surrey has hard water. Steam carries that scale onto mirrors and glass, so a fan that clears the room quickly helps on both counts. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- 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
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.
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.
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.
