Airtightness UK offers specialist building performance testing, including air pressure, ventilation, and sound testing, for new-build, retrofit, residential, and commercial projects across East Anglia and the UK. With engineers based in Suffolk, Essex, and Norfolk, the company provides fast, reliable, and fully certified testing with clear compliance reporting and practical on-site support. The team's background in carpentry, bricklaying, site management, and general building provides a unique understanding of construction details and their impact on building performance.
This hands-on experience allows Airtightness UK to effectively investigate problems, explain findings clearly, and offer practical advice to homeowners, site teams, and contractors. Services include air pressure testing for compliance with Part L, extraction system testing for Part F, and diagnostic testing using smoke, pressure, and thermal imaging to investigate air leakage and performance issues. They also offer sound insulation testing, heat pump sizing, and room integrity testing for gas fire suppression systems, isolation rooms, and smoke shafts.
Airtightness UK is committed to building lasting relationships by providing clear reporting, confidence in testing, and straightforward communication. They support projects from single self-build homes to large developments, coordinating testing with project programmes and delivery plans.
This property is undergoing multiple airtightness tests throughout the build to verify performance at each stage and confirm that the envelope remains consistently sealed. Based on the results so far, it is performing exceptionally well and may prove to be one of our tightest properties to date.
