We have used Richardson and Starling on two occasions. The first to install an ATMOS positive ventilation system in our downstairs flat and then later a Cyclone 7 extractor fan in our kitchen. The instalations were very well done, the workers were very professional and we are very happy with the finished products. Both products have resulted in better circulation of air throughout the house and much better control of humidity and condensation in our old granite building. Steven McLeavy has been very patient and helpful. We highly recommend Richardson and Starling (and EnviroVent.) Jackie Hardy the Contracts Co-ordinator has also been very available and helpful. Thank you to everyone at Richardson and Starling and EnviroVent
