We Test your ducts for leakage

Whether during construction of your ducting or extraction system, don’t wait until the ducts are under commissioning or operation to test your system for air leakage.

Smashing! provide complete duct leakage testing using smoke to locate and document leakage points in order for the client to repair the duct.

The procedure of smoke testing involves temporarily sealing the registers and diffusers and introducing theatrical fog into the duct system under slight pressure.


When using this qualitative testing method, previously invisible leaks can be easily identified as the smoke finds its way through any breaches in the duct system. Performing this test during construction can help to save considerable time and money by not having to seal the system at a later date.

Conducting a Duct Leakage Test program offers many benefits. In the short term, a building will be constructed and handed over more efficiently. In the long term the operator will have lower energy costs. In any building, finding 25% leakage is not unusual. With this figure in mind, making sure the duct system is as tight as possible will save you client money.
