Air tightness testing is an important part of understanding how a building performs in use. Excessive uncontrolled air leakage can increase heat loss, affect comfort and create delays where a project still needs to meet compliance targets.
The emphasis is always on clarity. We set out the process clearly, carry out the test methodically and provide the documentation needed for the next stage of the project.
The aim is not only to measure air leakage, but to give the project team information that is genuinely useful in moving forward.

The cost of air tightness testing in Tring depends on the type of building being tested, the overall size of the property and how easy it is to access and prepare the building for the test. A compact residential property will usually require less time on site than a larger commercial unit or multi-plot development.
Testing provides value beyond a pass or fail outcome. It helps reveal whether uncontrolled air leakage is likely to affect energy efficiency, comfort and the overall quality of the completed envelope.
By arranging testing at the right stage, project teams can reduce the risk of late surprises and avoid more expensive remedial work after handover deadlines become tight.
A clear measured result can also make project communication easier, because everyone involved is working from the same tested information rather than assumptions.

Clear Communication
We keep the process simple so project teams know what to expect before, during and after the test.
Practical Reporting
The output is designed to be useful, not overcomplicated, so the next step is easier to manage.
Project-Focused Scheduling
Testing is arranged with real build programmes in mind wherever possible.
Useful Follow-On Insight
If the result highlights issues, the findings help focus attention on likely leakage areas.

An air tightness test (also known as a blower door test) measures how much air leaks out of a building through gaps and cracks in the structure. A fan is temporarily fitted into an external doorway to pressurise the building, allowing engineers to measure the rate of air leakage. This helps determine the building’s energy efficiency and compliance with Building Regulations.
Yes. Air tightness testing is required under Part L of the Building Regulations for most new dwellings and commercial buildings in the UK. The test ensures the building meets the required energy efficiency standards before it can be signed off by Building Control.
Air tightness testing should be carried out towards the end of construction, once the building envelope is complete but before final finishes are installed. This allows any air leakage issues to be identified and fixed if necessary.
If a building fails the test, the tester will usually identify the main areas where air leakage is occurring. These gaps can then be sealed before the building is retested to achieve compliance with the required air permeability target.
