About Air Testing

We are a BINDT registered company and use equipment that is calibrated by UKAS laboratories.

Our testing procedures are also recognised by UKAS. We cover the whole of the south east of England. Our personnel are fully qualified, friendly and helpful.

They issue certified results accepted by building control throughout the UK.

Possible Air Leakage Areas

The areas listed below are common causes of uncontrolled air leakage, we recommend you take care and attention in sealing these areas whilst in the process of construction;

Intermediate Floors — Use joist hangers where possible, if built into the walls seal with a flexible sealant.

Behind Skirting Boards—seal between floors and walls

Behind Coving—seal between wall and ceiling

Boxed in Pipes & Soil Stacks—seal when pipes/soil stacks go out through the ceiling into the roof space

Behind Bath Panels—seal all surfaces and pipe work that penetrate the envelope of the building

Kitchen Units—seal all surfaces and pipe work that penetrate the envelope of the building

All Other Surfaces—pipe work and services that enters the building ensure a good seal

Badly Installed Trickle Vents—the test only allows for trickle vents to be shut and not sealed

Windows and Doors—ensure a good seal behind plaster board as well as decorators finishing mastic

Recess Lights—ensure they are fire check fittings that are fitted correctly

Loft Hatch—poor quality loft hatches often leak

Any Remedial Work to Floorboards—make sure any holes in timber floorboards are refitted correctly and sealed

Please do not hesitate to contact us if you have questions relating to the process of sealing any areas in preparation for the air tightness test.

This is an example of the Minneapolis blower door system that we use.
