Stains, mould and damp readings in bathrooms and laundries.

Sunbury 3429 · 6 August 2026

In short: A bathroom that looks fine can hide years of slow leaking. A moisture meter and a careful look usually show it.

Where leaks show

Stained ceilings, swollen skirtings, mould and damp floors around showers and baths.

Using a moisture meter

Readings around wet areas show where moisture is sitting behind the surface.

Evidence of past leaking

Subfloor staining and old repairs suggest a leak, even if it is dry on the day.

What the report says

It records where moisture was found and recommends a plumber or waterproofer where needed.

FAQ

Questions Sunbury owners ask about this

Can you see inside walls?

No. We use a meter and thermal camera, but nothing is opened up.

Is mould always a leak?

Not always. Poor ventilation also causes it. The report notes the likely source.

Can a Sunbury rental report name the mould species?

No. Laboratory testing is a separate specialist service.

Are leaks expensive?

They can be if left. That is why they are listed clearly.
