Strata & apartment leaks

The hardest leaks to pin down — and to resolve

In apartments, a leak in one lot often shows up in another, and the source can sit in common property. That turns a simple leak into a dispute about who’s responsible.

We locate the source non-invasively across lots and give you clear, documented findings — the evidence an owners corporation, strata manager or insurer actually needs.

What’s behind it

Why strata leaks are tricky

It’s rarely just the leak — it’s the access, the ownership and the paperwork.

  • The source sits in a different lot or in common property.
  • Access is needed across more than one apartment.
  • Responsibility depends on where exactly the leak originates.
  • Owners corporations and insurers need documented evidence.
  • Multiple trades get blamed without a clear diagnosis.
How we find it

How we help strata resolve it

  • Pinpoint the origin — thermal imaging and testing establish exactly where it starts.
  • Document clearly — a report with location, cause and photo evidence for the committee.
  • Support the claim — clear findings an insurer or strata manager can act on.
