Working in Johnstone
We work right across Johnstone — PA5 — and in neighbouring Paisley and Barrhead.
Being a smaller town does not change how we work in Johnstone: free survey, written quote, one team. In Johnstone flats, a new vent through an outside wall may need agreement from the other owners or the factor, so we raise it at the survey. If your Johnstone bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
Most of Renfrewshire and Inverclyde 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
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- A backdraught shutter and external grille, so cold air does not blow back in
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
Decisions to make first
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.
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.
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.
