Before you book in Winchester
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
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.
Noise
Fans and grilles are selected and attenuated to keep noise down.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
