Working in Rhondda
In Rhondda we cover CF40, CF41 and CF43; we also cover Tonypandy, 2.6 miles away, and Aberdare.
Homes in and around Rhondda vary, so we look at the floor, the walls and the water system before we price anything. For windowless bathrooms in Rhondda homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. In Rhondda flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Most of Mid Glamorgan 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
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- A backdraught shutter and external grille, so cold air does not blow back in
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.
Noise
Compare the stated noise level in decibels. Inline fans and low-speed continuous fans are much quieter in the room than budget axial fans.
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.
