Important: All air tightness testing should be carried out by a qualified & registered technician under the methods prescribed by ATTMA (Air Tightness Testing Measurement Association) technical guidelines.

Preparation: Before undertaking an on-site survey it is important to assess any technical drawings available relating to the premises in order that we can identify and calculate the space within the finished building.

The Air Tightness Test: This is carried out by typically positioning a fan (or fans) to an outside aperture such as a suitable doorway, we will then pressurise the whole building with specialised equipment using a scope of pressure changes.

Results: Preliminary results are typically available verbally on-site and a certificate will normally be issued within 24 hours. In the unfortunate event that a test was to fail, the client will be given 30 minutes immediately after test in order to rectify the problem by resealing where possible. There will be no further charge for the initial retest.
