Diagnose your leak
Four questions about what you can actually see — where the water shows, when it worsens, what it looks like, and which floor. The tool ranks the most likely causes from 40 documented failure patterns and gives you a confidence band, so you know whether the answer is solid or genuinely ambiguous. Free, instant, and it asks for nothing.
Start with what you can see
Two minutes of looking beats four questions
- Photograph it while it is actively wet. A dried stain tells a surveyor far less than a running one, and the photograph is the single most useful thing you can send us.
- Note whether it worsens with rain or with usage. Run a shower for ten minutes and watch. This one observation narrows the cause more than anything else.
- Check the area directly above and beside the damage, not only below it. Water travels along the underside of a slab before it drops, so the entry point is often metres from the stain.
- Do not chip into saturated plaster to 'see where it comes from'. It risks bringing material down and destroys the evidence needed to trace the path.

About this tool
How accurate is this?
It narrows the field; it does not diagnose a building. Four questions cannot account for what is behind a wall, and the tool says so — it returns a confidence band, and where two or three causes fit equally well it tells you that rather than picking one. Treat it as where a surveyor would start looking, not as a verdict.
Why does it ask when the leak gets worse?
Because that single question discriminates better than any other. A leak that tracks with rainfall points at the building envelope — terrace, facade, parapet, shaft. A leak that tracks with usage points at plumbing or a wet area. Getting that distinction right eliminates most of the wrong answers immediately, and it also settles most arguments about who is responsible.
Do I have to give my phone number?
No. The tool is entirely free and asks for nothing. It runs in your browser and no answers are sent anywhere. If you want us to look at it, there is a WhatsApp button at the end that pre-fills the result — but that is your choice.
Can I share the result?
Yes. Your answers are stored in the page address, so copying the URL and sending it to a committee member or your architect reproduces exactly the same result on their screen.
Send us the result and a photograph
A photograph taken while the leak is running, plus whether it tracks with rain or usage, is usually enough for a first opinion. The site inspection that follows is free.
