New Build Air Tightness Testing
Provisional Test: Test your house before plastering to find any leaks. This is the easiest & cheapest time to rectify any problems. – Prevention is better than cure!
Final Test: This Test will be carried out on completion of the building. It will give you the air changes per hour and the results will be the official result and will be used in the B.E.R Calculation
Existing Buildings
Smoke Test: We can find any source of air leakage in your house that is leading to draughts & heat loss. We will compile a report on the severity of all the problem areas found & recommendations on improvements
