Leak Detection Perth – Wilmac Plumbing

We at Wilmac Plumbing own and operate our own leak detection equipment. Our trained staff also have been locating leaks for other plumbing companies without their own equipment for many years.

We carry out leak detection service not only to our nearby suburbs like Wangara, Wanneroo or Joondalup, but it extends to all suburbs of Perth.

We also carry out leak detection for insurance companies and real estate agents. It can be very difficult to locate leaks that develop below ground, in walls or below concrete slabs without proper equipment.
