Working in Alton
We work right across Alton — GU34 — and in neighbouring Bordon and Farnham.
Being a smaller town does not change how we work in Alton: free survey, written quote, one team. If your Alton bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. For windowless bathrooms in Alton homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
Supplies across most of Hampshire are hard. 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
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
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.
