Why Advanced Leak
Detection Matters

Hidden leaks can cause:

Traditional methods rely on guesswork. Advanced leak detection finds the exact source quickly, avoiding costly excavation.

We combine multiple methods to locate even the hardest-to-find leaks:

Common signs you may need professional leak detection include:

Thermal imaging cameras → reveal hidden moisture behind walls and floors
Acoustic listening devices → detect underground pipe leaks by sound
Electronic leak detection → pinpoint exact locations of water escape
Moisture meters → confirm damp spots non-invasively
Pressure testing → identify drops in water lines

Our Leak Detection Process

1. Inspect the
property & assess signs (meter checks, visible water damage).

2. Use advanced technology to locate the source without excavation.

3. Confirm findings with pressure or tracer testing.

4. Provide upfront, fixed-fee repair options.

 Trustindex verifies that the original source of the review is Google. Had issue with having cold shower, was thinking of replacing the water tank (5 years old). Called Expand Plumbing (based on good reviews they have) and they sent Ben to our place within hours. He then simply clean the valve and we got hot water again with very reasonable fee (no call out fee). Ben was fantastic and explained to us the problems clearly. Highly recommended!!

 Trustindex verifies that the original source of the review is Google. Thank you Alec and Sarah! I know diddly squat about water pipes, so when our front water meter was going off like a frog in a sock, and it was almost 5pm - needless to say, I got a bit panicked. Sarah sent me the easy-to-navigate booking form, and instantly, Alec was on his way. Alec figured it was a water corp issue and he very accommodatingly called them for me and explained the issue. The nicest, fastest and professional service I have had in a long time. Expand to the rescue!

 Trustindex verifies that the original source of the review is Google. I recently had a fantastic experience with Expand Group Plumbing! They sent out a couple of young guys who were not only well-mannered but also efficient and professional. They got the job done quickly and made sure to clean up thoroughly before leaving. I couldn't be happier with the service I received. Highly recommend Expand Group Plumbing for anyone in need of reliable and quality plumbing services!
