How to Remove and Prevent Mould in the Garage


Mould, including potentially harmful black moulds, flourishes in damp environments with poor ventilation and limited sunlight. Consequently, it doesn’t take much time for mould to develop on organic materials like cardboard or drywall under such conditions. Garages often provide ideal conditions for mould growth unless homeowners take appropriate measures to reduce moisture. However, there’s no need to worry. You can prevent mould from spreading in your garage by following some simple steps. This article will guide you on how to eliminate mould in the garage and how to stop it from coming back.

Steps to Remove Mould in the Garage

  • Safety Measures: Before beginning the mould removal process, make sure to wear protective gear such as gloves, goggles, and a mask to avoid exposure to mould spores and cleaning chemicals.
  • Evaluate Mould Damage: Thoroughly inspect your garage to identify areas affected by mould growth, including any signs of black mould on walls, ceilings, floors, stored items, and other surfaces.
  • Ventilation: Open windows and doors to ventilate the garage and enhance air circulation, which aids in reducing moisture levels and dispersing mould spores during cleanup.
  • Clear Clutter: Declutter your garage to create more space for cleaning and maneuvering. Remove any items or objects that may harbor mould or obstruct access to mould-infested areas.
  • Dry Damp Surfaces: Address any sources of moisture in the garage, such as leaks or condensation. Use fans, dehumidifiers, or towels to thoroughly dry wet surfaces and prevent further mould growth.
  • Scrub Mouldy Surfaces: Prepare a mixture of water and mild detergent or dish soap in a bucket. Use a scrub brush or sponge to vigorously scrub mouldy surfaces, focusing on areas with visible mould growth. Rinse with clean, warm water and allow to dry completely. Avoid using bleach.
  • Use Mould Removal Products: For stubborn mould growth, consider using commercial mould removal products designed for use on garage surfaces. Follow the manufacturer’s instructions carefully when applying these products.
  • Employ Natural Remedies: You can also utilize natural solutions like white vinegar, hydrogen peroxide, or baking soda to eliminate mould in your garage. These natural agents effectively kill mould and are environmentally safer.
  • Dispose of Contaminated Materials: Discard any porous materials or heavily mould-contaminated items in the garage that cannot be adequately cleaned, such as cardboard boxes or old furniture. Seal them in plastic bags before disposal to prevent the spread of mould spores.
  • Preventive Measures: Take preventive actions to stop mould from returning to your garage by addressing underlying moisture issues, enhancing ventilation, and maintaining cleanliness. Consider installing a dehumidifier or ventilation fan to regulate humidity levels.
  • Regular Maintenance: Conduct regular inspections and cleaning routines in your garage to promptly identify and address any signs of mould growth. Keep the garage well-organized and free of clutter to minimize potential hiding spots for mould.
  • Seek Professional Assistance: If the mould infestation in your garage is extensive or if you’re unsure about the removal process, consider hiring professional mould remediation services. Experienced professionals can assess the situation and provide effective solutions for mould removal, such as PuroClean.

    Suggestions for Preventing Mould Growth in the Garage

    • Check for Leaks: Regularly inspect your garage for leaks, examining areas like the roof, floor, gutters, and pipes. Promptly repair any cracks or damages to prevent moisture from seeping in.
    • Seal and Insulate Garage Door: Properly seal and insulate your garage door to protect it from weather conditions. Replace worn-out weather stripping and ensure the bottom seal maintains elasticity. Consider installing a pre-insulated garage door panel for improved insulation.
    • Control Humidity: Garages are prone to high humidity levels, making them susceptible to mould growth. Enhance ventilation using vents and fans, and allow sunlight to enter for a few hours daily. Employ a dehumidifier to reduce moisture levels.
    • Utilize Waterproof Materials: Opt for mould-resistant drywall and waterproof paint for garage walls and concrete surfaces. Alternatively, consider using pre-coated aluminum or vinyl siding to enhance protection against water and mould.
    • Eliminate Standing Water: Remove any pooled water from your garage, whether it’s from precipitation, snow on tires, or car washing. Use a squeegee or mop to dry the area promptly to prevent mould formation.
    • Ensure Proper Drainage: Install a garage floor drainage system and ensure the floor has a suitable slope to divert water away from the garage. Proper drainage prevents water damage and potential flooding.
    • Extend Gutter Downspouts: Maintain clean and well-functioning gutters and downspouts to direct water away from your garage foundation. Extend downspouts at least 10 feet from the garage to prevent moisture buildup.
    • Use Waterproof Containers: Opt for sturdy plastic containers instead of cardboard boxes for storage in the garage. Plastic provides better protection against moisture and prevents mould growth on contents.
    • Manage Plant Growth: Keep vegetation away from your garage walls and windows to reduce moisture accumulation. Shrubs and plants near the garage can collect moisture and potentially cause leaks.
