Musty Smell in Your Basement? Here's What To Do

5 min read

A persistent musty odor wafting up from your basement can be an unwelcome occurrence in your home.

If you’re wondering how to eliminate the musty smell in your basement, we can provide a few solutions. Here are some ways to address the smell and the possible underlying causes of unwanted odors in your basement.

What Could the Smell Be?

In most cases, a musty smell in the basement could be a sign of mold and mildew. If your basement is prone to leaks and has poor ventilation, it may become an environment that can promote mold growth. Additionally, mold growth is a sign of an underlying issue, such as poor drainage, leaks in the foundation, and plumbing issues.

However, the smell could also come from other potential issues. If the odor is particularly bad, it could suggest that your drains or sewage waste are clogged or leaking, and their moisture seeps into your foundation and basement.

Finding the Issue in Your Basement

The first step on how to get rid of the musty smell in your basement is to find the source of the odor. In most cases, the scent results from mold or mildew growth caused by factors in your basement.

Hunt for any signs of mold and mildew on walls, flooring, or stored items. Don’t forget to check those hidden corners and hard-to-reach areas, as they can quickly become breeding grounds for dampness and mustiness.

Another common issue could be a water leak, whether it’s from a pipe, a faulty appliance, or even seepage through the walls or floor. Look for suspicious water stains, wet spots, or compromised objects, and trace them back to their source.

Address the Musty Smell

You can mask the musty smell in the basement through solutions like baking soda and products that can absorb odors. However, addressing the source is a more permanent and effective solution. If the musty smell is likely coming from mold, mildew, or water damage, some of the things you can do:

• Repair Windows and Doors: The musty smell could be from water leaks seeping from outside into the basement, especially when it rains.
• Call a Professional Plumber: They can handle cracked or leaking pipes that could add moisture to your basement’s spaces.
• Waterproof Your Basement: The leaks may come from your property’s foundation. If you can’t provide waterproofing treatment, consider installing a sump pump or upgrading your drainage system.
• Mold Remediation: If mold has developed on your walls, we recommend calling a professional mold remediation specialist to remove the mold. This can release mold spores that can continue to grow around your basement.

Take Preventive Measures

After making the repairs, your basement should be less vulnerable to musty smells. However, now that you know how to get rid of the musty odor in your basement, you should ensure it doesn’t develop mold or mildew. Some ways to do this include:

• Humidity Control: If your basement has limited options for ventilation, use a humidifier to remove excess moisture from the air.
• Use Heat on the Basement: Consider opening your basement windows during sunny days to let the sunshine warm up your basement. At night, shut your basement window and curtains to prevent condensation.
• Install a Sump Pump: If your basement is prone to dampness from leaking groundwater, your property could benefit from installing a sump pump. This collects water and pumps it away from your home, especially during heavy rains.
• Drainage Maintenance: Ideally, you should schedule a professional maintenance inspection for your drainage system at least once a year.

Final Steps To Remove the Smell

Once you’ve found the source and addressed the issues with your basement, there are some final steps you need to take to remove the lingering smell effectively.

• Promote Airflow: Open the basement windows to promote better air circulation.
• Remove Lingering Smells: You can use baking soda, white vinegar, clean cat litter, and other deodorizing products. These are likely to be more effective now that you’ve addressed the source of the smell.
• Basement Deep Cleaning: Use suitable cleaning solutions to mop the floors and spray any surfaces in your basement. If necessary, contact a professional to deep clean any carpets or upholstered furniture in the basement.

It may take several days before the musty odor is gone. We recommend deep cleaning your basement twice a year to prevent mold from growing undisturbed.
