How To Prevent Mold From Growing In The Garage

Mold thrives in moist environments with little sunlight and ventilation. Mold can quickly grow on cardboard and drywall, provided the right conditions are present. If homeowners don’t take the necessary steps to reduce moisture, garages can become breeding grounds for mold. But fret not. It is possible to keep mold from infesting your garage with simple steps.

Tips to Prevent Mold in Your Garage

  • Check your garage to make sure there are no leaks. Inspect all areas of your garage (roof, floor, gutters and pipes) to ensure they are in good shape. Repair any cracks or damage that you discover immediately.
  • Insulate and seal your garage door. You should replace any weather stripping that is ripped, ragged, or falling apart immediately. Also, inspect the bottom seal for wear, shrinkage and elasticity. Pre-insulated garage doors have a higher R-value, which is the measure of object resistance to conductive heat flow.
  • Reduce humidity. Garages can be susceptible to moisture from being more exposed to the elements. It may have high humidity (over 50%) which allows mold growth. Ventilation is key to controlling humidity. Fans and vents are recommended. Let sunlight in for at least two hours each day. To lower moisture levels, you can also use a humidifier.
  • Install waterproof walls. Whether you are building a garage from scratch or renovating an existing one, make sure to use mold-resistant drywall. Pre-coated aluminum siding or vinyl siding can be used for greater protection from water and mold.
  • Drain standing water. You can get garage water from many sources such as snow-covered tires, outside precipitation, washing your car, and even washing your car. To prevent mold growth, remove any remaining water using a mop or squeegee.
  • Proper drainage is essential. To avoid flooding and water damage in your garage, a garage floor drainage system will be essential. You should ensure that your garage has proper drainage and a sloped floor that diverts water away.
  • Extend gutter downspouts. Your home’s first line defense against rain is gutters and downspouts. Your downspouts should be at least 10 feet from your garage foundation to prevent moisture buildup. Ensure that your gutters are clean and maintained throughout the year.
  • Use waterproof containers. Mold is attracted to cardboard and paper. Use sturdy plastic storage containers instead of cardboard boxes to prevent mold growth in your garage. Plastic protects contents better and is not a source for mold food.
  • Limit the growth of plants around your garage. They can collect moisture and cause damage to your garage. Keep them away from garage windows and walls.
