A dMEV (decentralised mechanical extract ventilation) fan is a low-energy extract fan that runs continuously at a quiet trickle speed and boosts automatically when it senses humidity or a light switch. Because it never fully switches off, moisture is removed steadily instead of building up between showers.
Across Dunbartonshire the job is priced the same way wherever you are: what is fitted, how long it takes and how far we travel. Towns we cover include Kirkintilloch, Milngavie, Bearsden, Clydebank and Vale of Leven.
