How To Prevent And Get Rid Of Mould In The Garage

The tell-tale signs of mould with its concentrated black or green speckles are something that requires urgent attention. 

While mould can occur anywhere in your home, it can also be found in your garage either within the structure itself or on the surface of any of your garage contents. 

At Kay Garage Doors, we know the importance of keeping your garage in good working order, including ensuring it is free from mould.

Here are our top tips to prevent mould, plus how to effectively remove it from your garage.

Is Mould In The Garage Dangerous?

Yes. The simple answer is that mould, regardless of where it lives in your home or garage, is harmful to human health. The NHS warns that mould can cause respiratory problems, allergic reactions and skin irritations. It adds that those with pre-existing conditions along with children or the elderly should “stay away” from mould. 

Furthermore, mould can also cause structural damage to your garage, which may pose additional risks of injury if the building materials weaken. 

Signs Of Mould In The Garage

In Stirling’s climate, the early signs of mould include musty odours, visible stains on walls or the floor along with white, green or black discolouration. 

Look for condensation on windows, rusty spots on tools or equipment or peeling paint, as these can indicate elevated moisture levels. 

Pay close attention to the corners, behind storage units and near plumbing where moisture can accumulate, as this can create ideal conditions for mould to thrive. 

How To Prevent Mould In The Garage

To prevent mould in Stirling’s often damp environment, ensure proper ventilation with exhaust fans or vents to reduce humidity. Use a dehumidifier, particularly during wet seasons, to keep moisture levels low. 

Sealing any cracks in walls or floors can prevent water from seeping in, while promptly fixing leaks in plumbing or the roof can stop unwanted water entry. 

Regularly cleaning and decluttering also improves airflow and reduces the mould-friendly accumulation of dust and organic debris.

How To Get Rid Of Mould In The Garage

If you haven’t been actively preventing mould and now find it in your garage, prompt removal is crucial. 

The removal process depends on the type and extent of the mould. For light surface mould, a mixture of water and white vinegar can be effective, while stronger infestations may require specialised cleaners or bleach solutions. 

Porous materials like drywall or wood may need to be replaced if severely infested. Professional remediation might be necessary if black mould (Stachybotrys) is present due to its potential toxicity.

Types Of Mould That Can Appear In The Garage

White Mould On Concrete Garage Floor

White mould often appears on concrete garage floors in Stirling due to moisture seeping up through the porous surface. This fuzzy growth usually indicates high humidity or a water leak and should be cleaned using a stiff brush and mould-killing solution. Sealing the concrete can help prevent future occurrences.

Black Mould On Garage Ceiling

Black mould (often Stachybotrys chartarum) thrives on high-cellulose materials like wood or drywall. It appears on ceilings where leaks or condensation have created damp patches. This toxic mould requires immediate professional removal to ensure proper handling and disposal due to its potentially severe health risks.

Green Mould In The Garage

Green mould can develop on various surfaces like wood, drywall or insulation due to consistent moisture. It is frequently seen in corners or behind objects that trap moisture. Removing green mould involves undertaking a thorough cleaning with an antifungal solution and ensuring that the affected areas are allowed to completely dry afterwards.

How to Remove Mould From Garage Walls

Mould removal from garage walls requires careful handling to prevent spores from spreading. First, wear protective gear like gloves and a mask. Scrub the walls with a mixture of warm water and detergent or use a commercial mould remover. 

For severe cases, replace the contaminated drywall. Apply mould-resistant primer or paint after cleaning to minimise future growth.

Is Your Garage Door Mouldy?

Garage doors can also develop mould, especially in damp Stirling. Signs of mould include discolouration around the edges and a musty smell. 

Clean the affected areas using mould-killing solutions and ensure the door has a proper seal to prevent moisture infiltration. Regularly wiping down the door and ensuring proper airflow around it can further help avoid recurring problems.

Dealing With A Mouldy Garage? A Garage Door Replacement Can Help 

We hope the above tips help you understand how to prevent mould from occurring, plus how to effectively remove mould if you notice it growing in your garage.

However, if the mould problem is extensive or recurs despite cleaning efforts, consider replacing the garage door with a new, mould-resistant model. In particular, newer garage doors often have improved seals and ventilation options that can effectively prevent moisture buildup.
