Air Leakage Testing

An air leakage assessment smoke test identifies where your home is losing heat to draughts.

You can use the findings to improve your energy efficiency with small but effective home improvements.  This will be your first step to resolving high energy bills, eliminating draughts and creating a more comfortable home.

Air-Leakage

An air leakage assessment (or air tightness test) uses specialist equipment to gently force air to flow through the fabric of your home. The surveyor can measure how much air is escaping and track down where it is escaping from. An air leakage assessment gives you guiding steps to greatly improve energy efficiency which is often affordable and DIY.

Why am I spending so much on heating bills yet always feel cold?

Warm air escapes from our homes through cracks, little gaps and hard-to-find holes in the building fabric (walls, floors, windows and doors). An air-tight home retains heat better. Rooms stay warm and it takes less energy to do it, enabling you to live in a more comfortable environment. Your home can be losing up to 30% of its heat

“You can have the best insulated home in your area but if there are gaps in floors or openings, the expensive energy you have just paid for is still being squandered”

A leaky home means cold and uncomfortable rooms. They are more prone to condensation and mould causing respiratory and other health problems for some people.

Airtightness - Energy Prothech

An air tightness assessment could be right for you if…

  • You want to know how warm air is escaping so you can tackle it
  • You want to improve your indoor air quality and comfort
  • Can highlight cheap and effective ways to reduce energy costs

What to expect from an air tightness assessment

An air tightness assessment is quick and non-intrusive. On the day, the assessor will install a large fan in your doorway. The fan creates a pressure difference relative to the outside air. With all the exterior windows and doors closed (the assessor will seal vents and flues too), it forces the air to find its way out. It’s like inflating a tyre so you can find the puncture. The whole process takes about an hour and the occupants can remain inside the home during the test.

The assessor will carry out a smoke test using a specialist smoke gun (non-harmful smoke) around all openings and potential leakage points to identify where heat loss is occurring and record the outcomes in a visual report.

The assessment report can recommend improvements you can make to reduce the air infiltration of the property.
