Read on to learn more about how to stop mould growing in your garage. 

What causes mould in garages?

Mould is a type of fungus that requires moisture, organic material, moderate temperatures, and oxygen to grow. In the confined space of a garage, it finds an ideal breeding ground due to specific conditions that allow it to flourish.

The primary culprit for mould infestations in garages is dampness. Whether from leaking pipes or seepage through walls, moisture accumulates and creates an environment where mould spores can settle and multiply. Combine this with inadequate ventilation—a common issue in many garages—and the humid air can get trapped in the space and make surfaces damp.

Garages also often contain plenty of organic materials like cardboard boxes and woodwork benches. Mould thrives in cars, too. It can quickly spread across a garage and the possessions stored there. 

Another issue is the amount of damp possessions stored there, whether that is vehicles, shoes, or outdoor equipment.

A less obvious factor but equally important is temperature fluctuations within the space. When warm air cools down quickly it condenses on surfaces, making them damp. Garages often lack insulation compared to other parts of the home and therefore experience more extreme temperature changes.

Is mould dangerous?

Mould in your garage is not just an eyesore; it's a health hazard. Inhaling, ingesting, and touching spores can cause health issues like allergic reactions, asthma attacks, and respiratory problems. Exposure is especially hazardous for those with respiratory or skin conditions, elderly people, and young children.

Some types of mould also produce mycotoxins, toxic substances that can lead to more serious conditions, like fatal asthma attacks and sick building syndrome. A key sign of mould growth in your garage is showing symptoms of an allergic reaction when you enter it, such as sneezing or coughing.

Beyond the health concerns, it can cause property damage, too. Mould feeds on organic materials, causing them to degrade, weakening structures over time and leading to costly repairs.

How to remove mould from your garage

You may assume you can get rid of the mould with a DIY mould cleaning solution, like scrubbing the mould with some bleach, but this is not always reliable or safe. Mould removal is not just about cleaning visible growth - you must address the tiny invisible spores that help it spread.

Mould cleaning is dangerous without the right protective gear, as well, and you could put your health at risk during removal.

To effectively combat this issue, professional expertise is key. Specialists mould cleaners are equipped with the necessary tools and know-how to safely remove mould without spreading spores throughout your property or causing harm to themselves or others. They use high-grade equipment and methods tailored for the thorough eradication of all types of mould.

They will even be able to assess the extent of infestation and what has caused it. Having eliminated the mould, they will even provide advice on keeping your space mould-free moving forward. Professionals will also be able to safely remove mould in hard-to-reach areas, like mould on you garage ceiling. 

How to prevent mould in the garage

Preventing the growth of mould in your garage is an absolute must, not only for keeping the structure intact but also to protect your wellbeing.

Improve ventilation

A well-ventilated space can discourage mould growth by reducing moisture levels. Start by ensuring that any existing vents are clear from obstructions. You might want to install additional air bricks or a mechanical extraction unit if natural ventilation is not cutting it.

Opening doors and windows regularly will also help circulate air and reduce humidity. Fresh air can even dry out damp areas.

Maintain low humidity levels

To keep humidity down, consider using a dehumidifier, especially during the winter months when condensation is more likely to occur on cold surfaces. 

You should also waterproof garage walls with the appropriate sealants which can prevent external moisture seeping into your garage space.

Tackle leaks promptly

If you discover leaks, act fast. Water ingress provides perfect breeding grounds for mould colonies so fix any roof or pipe leaks as soon as you spot them.

You should inspect your garage regularly looking out for these issues so you can have small ones sorted out before they become big problems.
