Working hours
Most Dunoon businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Noise
Fans and grilles are selected and attenuated to keep noise down.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
