Ductwork installation in Dorset
Spiral and rectangular galvanised ductwork, hung, insulated and sealed, across Dorset.
- From £45 + VAT per metre
- Free survey
Ductwork carries air between the fan or unit and the rooms it serves, and how it is sized, hung and sealed decides how well the whole system performs. We supply and install spiral and rectangular galvanised ductwork, fittings, dampers, insulation and access panels.
Every job in Dorset gets a written quote before it starts and a commissioning record when it finishes. We cover Bournemouth, Poole, Weymouth, Christchurch and Ferndown and the villages around them.

What ductwork installation involves
Undersized or leaky ductwork forces fans to work harder and makes systems noisy. We work to recognised sheet-metal ductwork specifications, seal joints, fit access panels for cleaning and insulate ducts that run through cold spaces or carry cold air. We install for our own ventilation systems and for other contractors, from short runs in a shop to full warehouse and office distribution.
Spiral ductwork
Round galvanised ductwork for supply and extract runs.
Rectangular ductwork
For larger volumes or limited ceiling depth.
Insulation and fire dampers
Thermal insulation and dampers where ducts pass through compartments, as designed.
