Ventilation for new builds, extensions and lofts in Renfrewshire and Inverclyde

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.

Our team is based in Great Barr, Birmingham, and we work throughout Renfrewshire and Inverclyde, from Port Glasgow, Paisley, Greenock, Newton Mearns and Renfrew. The survey is free for new installations on the UK mainland, and the quote that follows is fixed and in writing.
