Garages in Aurora often serve multiple purposes—from parking and storage to workshops or home gyms. But because they are typically less insulated and more exposed to temperature and moisture fluctuations, garages can become prime breeding grounds for mold and mildew.
You can use warm water and detergent to remove some existing mildew yourself, but mold prevention is always better than cure. Fortunately, with a few proactive steps, you can stop mold from taking hold and maintain a clean, dry, healthy, and perfect environment for your garage. Whether your garage is attached or detached, these strategies from our technicians at a trusted garage door repair company are practical and easy to implement.
Why Mold and Mildew Thrive in Garages
Mold and mildew are types of fungi that grow in damp, dark environments with poor airflow. Garages often experience humidity from snow-covered cars, wet tools, or leaky walls. Add to that minimal ventilation and concrete floors that trap moisture, and you’ve got the perfect conditions for mold to flourish. Once exposure to mold spores occurs, they can spread quickly—especially on cardboard boxes, wood surfaces, or any organic material stored in the space.
Improve Ventilation and Air Circulation
One of the most effective ways to combat mold in garage is by improving airflow. Installing vents, exhaust fans, or simply keeping your garage door open periodically can make a big difference. If your garage has windows, opening them on dry days helps air circulate, brings in natural light, and removes trapped humidity. Ceiling or wall-mounted fans are also useful, especially if you use your garage frequently.
Control Moisture Levels with Dehumidifiers
Excess humidity is the number one contributor to mildew and mold growth. Using a dehumidifier in your garage can reduce moisture levels, particularly in the spring and summer when humidity peaks. Modern dehumidifiers come with built-in sensors that maintain ideal humidity levels between 30 to 50 percent. If your garage doesn’t have electrical outlets, moisture-absorbing products like silica gel or calcium chloride can be placed in corners or near stored items, which are a source for mold.
Seal Cracks and Fix Water Intrusion Points
Garages are prone to leaks from weathered seals, foundation cracks, or gaps around windows and doors. This makes them a prime environment for mold. Sealing these areas with caulk or weatherstripping prevents rainwater and ground moisture from seeping in. It’s also important to ensure your garage door has a tight bottom seal and that the concrete floor slopes slightly toward the door to direct water outward. Regular inspections after heavy rains or snowmelt can help identify problem spots for mildew early.
Avoid Storing Damp Items Inside
Wet items left in the garage are a leading cause of black mold. Towels, sports gear, snow-covered boots, and even garden tools can introduce enough excess moisture buildup to start a mold issue. Make it a habit to dry off items before bringing them inside, especially in colder months. Consider installing garage wall hooks or shelving to elevate these items off the floor and allow airflow around them.
Use Mold-Resistant Materials for Storage
Where possible, replace cardboard storage boxes with plastic bins, which don’t absorb moisture and are easier to clean. Choose metal or plastic shelving instead of wood, and avoid placing items directly on the floor. Using raised platforms or pallets can prevent moisture from collecting underneath stored goods and improve air movement across the space.
Maintain a Clean Garage Environment
Dust, dirt, and organic matter like leaves or paper can feed mold if they get damp for a couple of hours. Avoid eating in your garage as mold can grow on a food source. Regular sweeping, vacuuming, and removing clutter can help prevent mold spores from finding a home. Also, inspect stored items periodically, especially during seasonal changes, to ensure there are no signs of mildew buildup on surfaces.
Schedule Regular Garage Inspections
Every few weeks, checking your garage for leaks, signs of condensation, or musty smells can help you act before a minor moisture issue becomes a major problem. Pay attention to areas behind shelving, around windows, and under stored items where air circulation may be limited.
Protect Your Garage from Mold Year-Round
Left unchecked, garage mold not only creates unpleasant odors and stains, but it can also damage your belongings and negatively impact air quality in your home. Preventing mold and mildew in your garage takes a combination of airflow, moisture control, natural light, cleanliness, and maintenance. The climate in Aurora can vary dramatically throughout the year, so adjusting your strategy seasonally for the ideal environment is essential. Whether it’s using a dehumidifier in the summer or checking seals before winter, staying proactive ensures your garage remains a safe and usable space.
