Working in Blackwood
We work right across Blackwood — NP12 — and in neighbouring Gelligaer and Risca.
Blackwood gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We check the duct route at Blackwood surveys, because a short, straight run to outside matters more than the fan's headline figure. In Blackwood flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Water hardness varies across Gwent: some supplies are soft, others moderately hard or hard. Scale is a minor issue next to condensation, which is what a properly sized extractor fan is for. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Making good around the fan and checking that it extracts properly at the grille
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
Decisions to make first
Replacement air
A fan needs air to replace what it removes, so leave a gap of around 10 mm under the door or fit a door grille. A sealed room starves the fan.
Axial, centrifugal or inline
Axial fans suit short, straight runs; centrifugal fans cope better with longer ducts; inline fans sit in the loft and are the quietest in the room.
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.
