The steps for a project in Seaham
Assess

Points to plan for in Seaham
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.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Leased premises
If your Seaham premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
