Ventilation for new builds, extensions and lofts in Ayrshire

New homes, extensions and loft conversions need ventilation that meets the building regulations and is tested before sign-off. We design the system, install it at the right stage of the build, measure the airflows and provide the commissioning information building control asks for.

Every job in Ayrshire gets a written quote before it starts and a commissioning record when it finishes. We cover Irvine, Kilwinning, Troon, Prestwick and Saltcoats and the villages around them.

Commissioning only

Testing and paperwork for systems installed by others.
