Working in Dumfries
In Dumfries we cover DG1 and DG2; we also cover Locharbriggs, 2.6 miles away, and Annan.
Homes in and around Dumfries vary, so we look at the floor, the walls and the water system before we price anything. If your Dumfries bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. Fans fitted in Dumfries bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Supplies across most of Dumfries and Galloway are 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
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- 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
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.
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 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.
