Ductwork installation in Norfolk

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.

We carry out ductwork installation across Norfolk, including King's Lynn, Thetford, Bowthorpe, East Dereham and North Walsham. Prices use East of England rates. Surveys for new installations are free on the UK mainland, with a written quote afterwards.

What the work 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.

Insulation and fire dampers

Thermal insulation and dampers where ducts pass through compartments, as designed.

Access panels

Fitted for future cleaning and inspection.

Spiral ductwork

Round galvanised ductwork for supply and extract runs.
