Working in Lisburn
We cover every part of Lisburn, including BT17, BT26, BT27 and 1 more postcode districts, and nearby Belfast (6.7 miles) and Castlereagh (7 miles).
In a city the size of Lisburn, parking and access for a skip are worth sorting before the start date — we will ask at the survey. In Lisburn flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey. Fans fitted in Lisburn bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Most of County Antrim 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
- Making good around the fan and checking that it extracts properly at the grille
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
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.
