Ventilation for new builds, extensions and lofts in County Tyrone

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.

If you are anywhere in County Tyrone, send the postcode and a few photos and we will tell you what we would recommend. Towns we cover include Strabane, Dungannon, Cookstown and Omagh.
