Non-Invasive Technology

Find the leak. Fix the problem. Protect your property.

Traditional leak finding often means guesswork and damage. We use advanced electronic and thermal equipment to locate leaks accurately—behind walls, under tiles, and in slabs—before they cause major structural issues.

  • Acoustic leak detection for pressurised lines
  • Thermal imaging to trace hot water and underfloor leaks
  • Moisture mapping to identify hidden damp
  • Minimal cutting, faster repairs, lower reinstatement costs

Common signs you need leak detection:

  • Unexplained high water bills

  • Damp walls, ceilings, or bubbling paint

  • Warm spots on floors

  • Sound of running water with closed taps

  • Mould, mildew, or persistent damp smells

Insurance-friendly reporting: We provide clear documentation and photos that support insurance claims for water damage.

FAQs

Answers to common leak detection questions.

If you don’t see your question here, include it in your quote request and we’ll gladly help.

How do I know if I need professional leak detection?

If your water bill has spiked for no clear reason, you see damp spots, hear water running with closed taps, or notice mould and musty smells, specialised leak detection is recommended. Our team can advise whether a call-out is necessary based on your description and photos.

Will you need to break tiles or walls?

Our goal is always minimal damage. We use acoustic, thermal, and moisture detection equipment to pinpoint leak locations as accurately as possible. In many cases only a small, targeted access point is needed instead of large areas being removed.

Do you also repair the leak and damage afterwards?

Yes. 3bl Entity CC is a full plumbing and construction firm. We can perform the plumbing repairs, as well as any associated construction, tiling, and finishing work—so you deal with one accountable contractor from start to finish.

Do you work with insurance companies?

We regularly assist clients with insurance claims and can provide detailed reports, photos, and quotations that many insurers require. Final claim decisions always remain with your insurer, but our documentation is prepared with that process in mind.
