- Describe the symptoms. Call or email with what you see, hear or smell, and when it appears.
- On-site investigation. Non-invasive methods narrow the search: acoustic, thermal, moisture, tracer gas or line tracing as needed.
- Confirm the source. Every clue is confirmed by a second method before it is reported.
- Written report. Findings, evidence, limitations and next steps, formatted for owners, managers and insurers.

Common questions
Do you do the waterproofing or repairs?
No. We investigate, test and document; repairs are performed by envelope, waterproofing or plumbing contractors.
Can you test without opening walls?
Often yes, using spray and dye testing with interior observation. Some concealed details need a small access point.
What if the leak does not show during testing?
The report will say so and describe the conditions to watch for. Weather-dependent defects sometimes need monitored retesting.
Do you work with strata and property managers?
Yes. Reports are formatted for councils, managers, insurers and warranty providers.
