Before you book in Coleraine
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
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.
