Working in Coleraine
As well as Coleraine itself (BT51, BT52 and BT55), we survey in Limavady, Magherafelt and Derry.
Homes in and around Coleraine vary, so we look at the floor, the walls and the water system before we price anything. If your Coleraine bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. We check the duct route at Coleraine surveys, because a short, straight run to outside matters more than the fan's headline figure.
Water across much of County Londonderry 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 fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- Making good around the fan and checking that it extracts properly at the grille
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
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.
Intermittent or continuous
An intermittent fan runs during and after use. A continuous fan runs quietly all the time at a low rate and boosts when humidity rises.
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.
