Working in Annan
In Annan we cover DG12; we also cover Dumfries, 15.1 miles away, and Locharbriggs.
Annan gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We check the duct route at Annan surveys, because a short, straight run to outside matters more than the fan's headline figure. If your Annan bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
Water across much of Dumfries and Galloway 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 backdraught shutter and external grille, so cold air does not blow back in
- 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
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
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.
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 Scotland
In Scotland, the Technical Handbook also uses 15 l/s extract for a bathroom. A replacement fan rarely needs a building warrant, but forming a new bathroom may.
