Working in Bangor
We work right across Bangor — LL57 and LL59 — and in neighbouring Caernarfon and Llandudno.
Bangor gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Bangor 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. If your Bangor bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
Most of Gwynedd 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
- Making good around the fan and checking that it extracts properly at the grille
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- 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.
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.
