At Dane’s Drains, we investigate drainage and moisture-related issues across Sydney’s Upper North Shore to help identify whether poor drainage, water ingress, leaking pipes or subfloor moisture may be contributing to the problem.

Rather than simply treating the visible mould, our focus is on helping identify where the moisture is coming from.

Mould is often a symptom of a bigger moisture problem

Cleaning mould may improve its appearance, but if the underlying source of moisture remains, the problem can continue to return.

Excess moisture around or beneath a property can be associated with drainage problems such as leaking underground pipes, poor stormwater drainage, water ingress or inadequate subfloor drainage.

That’s why identifying the source is an important first step.

Signs you may have a moisture or drainage problem

The visible problem isn’t always where the water is entering, which is why a proper investigation can be important.

What can cause ongoing mould & humidity?

Where drainage is involved, common contributing factors can include:

Our investigation process

Every property is different, so we begin by investigating the likely source rather than assuming the cause. Depending on the property and symptoms, this may include:

Once the source has been identified, we can explain the findings and recommend the most appropriate drainage solution.

Fix the cause, not just the mould

If poor drainage is contributing to mould or humidity, treating the surface problem alone won’t address the underlying issue.

Depending on what we find, the solution may involve repairing damaged drainage, improving stormwater management, addressing water ingress or improving drainage beneath or around the property.

Our goal is to help stop excess moisture at its source wherever the drainage system is responsible.
