Working in Brecon
In Brecon we cover LD3; we also cover Merthyr Tydfil, 13.7 miles away, and Ebbw Vale.
Being a smaller town does not change how we work in Brecon: free survey, written quote, one team. If your Brecon bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. In Brecon flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Water across much of Powys is soft. 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
- A check of the room, any existing fan or vent, and the shortest route to the outside
- A backdraught shutter and external grille, so cold air does not blow back in
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- 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.
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.
