G.A.S General Building Services Ltd

G.A.S General Building Services Ltd specialises in diagnosing and solving building performance problems such as heat loss, condensation, damp, mould and draughts in residential properties.

Using professional diagnostic tools including thermal imaging inspection, blower door air leakage testing and humidity assessment, we identify insulation defects, hidden air leakage paths and cold bridges within the building envelope.

Our work follows building performance and Passive House design principles to ensure effective and long-term solutions. Where improvement works are required, installations such as insulation upgrades or airtightness improvements can be verified with before-and-after testing.

With over 15 years’ experience working with high-performance insulation and building envelope systems, our goal is to improve comfort, reduce heat loss and resolve the root cause of building problems.
