Ductwork installation in Wiltshire

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 Wiltshire, including Trowbridge, Chippenham, Melksham, Warminster and Calne. Prices use South West rates. The survey is free for new installations on the UK mainland, and the quote that follows is fixed and in writing.

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.
