Air Tightness testing (also known as Airflow, Air leakage, Blower door test or Air Permeability testing) is an essential requirement for new homes in order to comply with 'Part L' of the Building Regulations. This measures if or where the air is escaping or entering the property in uncontrolled ways, whilst ventilation is taking into account. 

Another important reason to have an Airflow test is the impact air leakage would have on the building's EPC (Energy Performance Certificate). An EPC is where the energy efficiency of the building is measured. Measuring the Airflow will indicate whether the property's insulation and the building have been sealed correctly.

We offer competitive pricing, a full report, including any potential issues. Please see under the 'what we do' tab for more information.

Air permeability testing and consultancy to help you comply with regulations

The Airflow test enables you to learn if there is air escaping or entering your property in uncontrolled ways, such as cracks in doors and windows. This test will provide you with a detailed report of where these leaks are happening, photographs and how these issues can be resolved.
