Air Leakage Testing

We are a Norfolk based company, providing air leakage testing to all of East Anglia & more. This includes Norfolk, Suffolk, Essex, Cambridgeshire, Hertfordshire, Bedfordshire, Buckinghamshire, Lincolnshire and London.

We offer a fast, professional & reliable service, doing our best to make the process as easy & stress free as possible. All of our clients will receive a booking confirmation email, detailing an accurate time slot for our arrival, along with multiple attachments focusing on how to ultimately pass your air leakage test. Once the test is complete & passed, we will issue your official ATTMA certificate, by email, within 24 hours. This certificate can then passed on to your SAP assessor & Building inspector in aid of your building completion certificate.

Coming from a construction background, we view every job from a builders point of view. Meaning we understand the stress involved in achieving a completion certificate, so we do our best to make the air testing aspect of this as stress free as possible.

The Testing Process

  • The overall Air Leakage Testing process is normally completed within an hour and a half of our arrival. On more unique domestic properties or commercial buildings, this may be slightly longer.

  • Before we set up our equipment, we complete a quick visual inspection of the property, looking out for any obvious problematic areas, which will likely need to be rectified to achieve a pass.

  • We then set our equipment up, usually in your front door. Once the equipment is running, we proceed to reduce / drop the pressure in the dwelling 50pa lower than that of the outside world. 50pa is equal to less than 0.01PSI.

  • Once the equipment has reduced the pressure within the dwelling, the handset will provide us with an estimated Air Leakage figure, provided in m3/hr/m2@50pa. From this, we are given a good indication of whether the dwelling is going to pass the test first time, or if additional remedials are going to be required.

  • If no additional remedials are required, we can then proceed with the final testing process & start taking our final figures. If the estimated leakage rate is looking higher than likely required, we then proceed with the leakage identification process.

  • Once the air testing process has been completed, your official ATTMA certified Air leakage Testing certificate will be issued upon our return to the office. This is normally completed & ready for issue on the same day (maximum of 24hrs after testing was completed).
