Building Pressure Assessments
​Air pressure testing plays a crucial role in understanding how efficiently a building retains heated or cooled air. When carried out by Air Tightness Assessors Ltd, it provides clear insight into the level of uncontrolled airflow caused by gaps or cracks within the building fabric. Using advanced tools, we measure leakage in cubic metres per hour per square metre of the envelope, offering reliable data to guide improvements. Our experienced, family-run team ensures every assessment is handled with precision and professionalism, helping both homeowners and businesses achieve better comfort, reduced energy waste and full compliance with relevant standards.
