Working in Ammanford
We cover every part of Ammanford, including SA18, and nearby Clydach (8.5 miles) and Gorseinon (8.8 miles).
Ammanford gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We check the duct route at Ammanford surveys, because a short, straight run to outside matters more than the fan's headline figure. In Ammanford flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Most of Dyfed is supplied with soft water. Even so, condensation is the bigger problem in any bathroom, and a properly sized extractor is what deals with it. 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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- 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
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.
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.
Rules that apply in Wales
Wales has its own Part F with similar extract rates, and its own Part P, under which new fan wiring in a bathroom is notifiable.
