Had a potential leak from the heating system under a concrete floor somewhere.
Frank arrived on time and got straight to work to find the source of the leak. He found the leak in the dining room under a concrete floor somewhere. Frank dug up the floor and repaired the leak. Very professional, explained everything and tied up afterwards. Would highly recommend this company.

Stress free experience
Our water company advised we had a leak though no visible signs anywhere on the property. Found ADI Proleak via Google. Came out to us the following week. Leak found under the driveway and repaired same day. First class job, very professional and caring to my elderly mother. Put everything back as if there'd never been a problem. Brilliant! Would totally recommend this company.

Good company - would recommend
Scott from ADI was great, thorough and reassuring. And, most importantly, found the leak! Even though I was out at work he kept in touch and when I eventually came home I found everything repaired and the heating working again. The ADI customer support has also been good.

Mitcham Chlorine Leak Detection for Swimming Pools?
Noticing that your pool’s chlorine levels are dropping faster than usual? It’s not just natural evaporation, it could be a hidden leak silently draining both water and chlorine.

What Causes Chlorine Loss in Mitcham Pools?

If you're constantly adjusting chemical levels with no improvement, you may need expert chlorine leak detection in Mitcham.
Why Mitcham Chlorine Leaks Are a Problem for Pool Owners
Losing chlorine not only affects your pool’s balance, but it can also lead to:
- Algae and bacteria growth
- Eye or skin irritation for swimmers
- Cloudy, green, or unpleasant-smelling water
- Long-term damage to your pool structure
All of this usually points to a leak that’s worsening, and chemical leaks can cost more than you think if left unresolved.
