Rising Damp


So why is our expert ventilation company talking about rising damp on its website?

Over many years, and after working with over 5,000 homeowners, we know that people often THINK they have a rising damp issue but actually have a subfloor ventilation issue. (see our separate page on subfloor ventilation)

Rising damp is also commonly known as salt damp or salt attack. It carries soluble salts up into the masonry, known as efflorescence. The most common symptom of rising damp is peeling or flaking paint or render on the walls. In extreme cases (very rare) you may notice mould on the wall where the paint/render is damaged. This dampness can affect the indoor air quality, but if the mould is isolated and there is no obvious musty smell inside the home, or if there is no visible mould on clothing or furniture, then you likely have a simple, treatable issue.

A ventilation system will not solve a genuine rising damp issue – but a ventilation system will solve the issues that many homeowners THINK is a rising damp issue.

Many homeowners often spend thousands of dollars on unnecessary plumbing and drainage work to combat rising damp. What’s not often explained is that rising damp comes from subterranean moisture at foundation level – ie below ground level – so surface drainage solutions can yield little improvement.

Mouldbuster, a Sydney based company, aim to provide viable products and solutions to household mould invasion, including solutions to rising damp. Mouldbuster has the skills and experience to understand your issue and advise you of your remedial options.

We will never recommend a solution that will not materially solve your problem. If the issue is beyond our expertise, we will tell you.
