Signs of Mould in Your Property

Before we discuss the causes of mould in a rental property, here are a few signs that you have it in your property.

Visible Growth and Discolouration

A clear sign of mould infestation is often its visible growth on surfaces, appearing as unsightly black, green or white patches. It can occur anywhere in the house, although certain areas like bathrooms, kitchens, basements and other areas exposed to moisture are particularly susceptible. It can also grow behind furniture, within walls or under floorboards, where it may go unnoticed. 

Unpleasant Odour

Mould doesn’t just leave a physical trace; it often brings an unpleasant, musty odour that disrupts the freshness of the indoor environment. This smell can persist even if the mould is not visible to the naked eye, such as when hidden behind walls or under floor coverings. 

If you are a tenant and there’s an odd, lingering smell in your space that doesn’t go away with regular cleaning, it’s worth a deeper investigation. This unusual smell can be an early warning sign of a mould problem that needs to be addressed.

The Cause: What Is Responsible for Mould in a Rental Property?

Knowing the underlying causes is essential for effective prevention and management. Below are the primary factors responsible for mould growth in rental properties. 

Moisture and Lack of Ventilation

Mould thrives in moisture-rich property with poor ventilation. Moisture is the lifeblood of mould, and its presence, whether from everyday household activities like showering, cooking or leaks in the plumbing system, provides a conducive environment for mould growth. 

External factors such as the property’s geographic location can play a part. Regions with high humidity levels, such as New South Wales, are particularly susceptible. Given this, it’s little surprise that the issue of mould in rental property  is a common and pressing concern. 

Inadequate Maintenance

While natural elements undoubtedly play a significant role in mould growth, human factors cannot be overlooked. Inadequate maintenance is a contributing element that can invite or aggravate mould issues in a rental property. 

That is why, landlords or property managers must respond promptly and adequately to tenants’ reports of leaks, dampness or other problems that might lead to excessive moisture. Neglect or delayed responses to these issues can result in moisture build-up, which creates an ideal breeding ground for mould. 

How to Handle Mould in a Rental Property

You need effective strategies and actionable steps to address mould-related concerns in your rental property. Check out the tips below that can help you prevent and handle mould issues.

Ensure Proper Ventilation

One of the most effective and simplest methods to prevent mould growth is ensuring that the property is well-ventilated. Establish habits that promote air circulation, such as opening windows regularly, particularly after activities that generate a lot of steam, like cooking, showering or even doing laundry indoors. These actions improve the air quality within the property and effectively drive out damp air, replacing it with drier air from outside. 

Maintain the Property

It’s important to remember that regular property checks and immediate repairs of any found faults can contribute significantly to preventing mould growth. Leaky faucets, damp walls or faulty gutters can be breeding grounds for mould if left unattended. Therefore, you need to address these issues promptly. 

Fixing leaks as soon as they are discovered and ensuring that gutters and drainage systems are in good working condition will help prevent water ingress. This reduces the likelihood of mould infestation. By implementing such preventative measures, you can avoid expensive mould removal costs and enhance the longevity and value of your properties.

Regular Inspection

Regular inspections are not just recommended but essential to effectively manage mould in a rental property. This is especially true for damp areas, such as bathrooms, basements and windows, where condensation often collects. 

Proactive inspection and the subsequent early identification of mould signs that might otherwise go unnoticed by untrained eyes can nip the problem in the bud. It allows for timely remediation before the mould problem spreads and becomes more extensive, complex and expensive.
