Smoke Test
Smoke testing is one of the most effective ways to locate hidden leaks, cracks, and unwanted odours in drain and vent systems. By introducing harmless, non-toxic smoke into your lines, we can quickly identify exactly where air or water is escaping — even in areas that are underground, hidden behind walls, or difficult to access.
