1. Water leaks

Leaks are one of the main causes of mold growth in homes. Mold will begin to form when there is excess moisture and it is not properly dried out. Leaks can occur in a variety of places, from pipes and faucets to windows and roofs. If you notice dripping water or dampness anywhere in your home, make sure that it is promptly wiped up with a towel and readied for repair as soon as possible. For example, if you live in Montreal when snow melts or heavy rain occurs and leaks start to happen, you would need a professional to do the repairs so mold does not occur.


2. Poor ventilation

If you do not have proper ventilation in your home, this can also cause mold to accumulate. Mold thrives in dark and damp areas, so if your home does not have a lot of airflow and light, it can be more prone to mold growth. Make sure that you keep your air vents and windows open as often as possible, especially in areas where mold is known to grow frequently, such as basements or bathrooms. Additionally, try to avoid placing items too close to walls or ceilings, as they can block ventilation pathways and prevent proper air circulation.


3. Humidity

In addition to poor ventilation, high humidity levels can also cause mold growth. Having your air conditioning on during the summer months is a great way to keep humidity in check, but if you live in a humid climate or have high levels of moisture in your home year-round, you may need to make additional efforts. Consider investing in a dehumidifier or purchasing an air purifier that can help control the humidity levels in your home. Additionally, make sure that there are no leaks or water damage anywhere in your home as these will only increase the amount of moisture and contribute to more mold growth.


4. Clutter

Cleaning up any clutter in your home is another simple step you can take to prevent mold growth. Clutter not only makes it harder to spot mold but can also provide the perfect breeding ground for mold spores. Keep your home as clean and clutter-free as possible to make it less inviting for mold. Additionally, you should clean up any visible mold immediately, and make sure to wear protective gear such as a mask, gloves, and goggles when doing so. If you see any mold on your walls or ceilings, be sure to get help from a professional mold remediation company as soon as possible.


5. Foods

Certain food items can also attract mold, so it's important to be careful about what you're storing in your pantry or fridge. Foods that are high in sugar or starch content are especially prone to mold growth, so be sure to check expiration dates and keep an eye out for any signs of mold before eating anything. If you do find mold on food, it's best to throw it away immediately to prevent the spread of spores. It's also a good idea to clean your pantry and refrigerator regularly, especially after any big grocery trips where you might be bringing in new items.


6. Not Using an Air Filter

If you want to prevent mold spores from circulating in your home, it's important to use an air filter. Air filters can help remove mold spores from the air, making it less likely for them to settle anywhere in your home and start growing. Using an air filter can also prevent you or any family members from breathing in mold spores, which may cause respiratory issues such as asthma and allergies. You can easily find a high-quality air filter that fits your needs at most home improvement stores or online retailers. Just make sure to check the size of your vents before purchasing a new filter so that you get one that works well with your current system.
