Working in Bangor
As well as Bangor itself (BT19 and BT20), we survey in Newtownards, Carrickfergus and Newtownabbey.
Bangor is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. In Bangor flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey. We check the duct route at Bangor surveys, because a short, straight run to outside matters more than the fan's headline figure.
Supplies across most of County Down 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 fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Making good around the fan and checking that it extracts properly at the grille
- A backdraught shutter and external grille, so cold air does not blow back in
Decisions to make first
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.
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.
Rules that apply in Northern Ireland
In Northern Ireland, ventilation is covered by Technical Booklet K, and building control is involved where a new bathroom is formed. There is no Part P, but the fan should be wired, tested and certified to BS 7671.
