Even a finished basement can contain high pollution levels and since these pollutants rise due to their buoyancy they can often invade the living space on the upper floors. Basements often have a bit of a musty smell to them and this is because certain types of wallboard and carpeting absorb moisture through the home’s foundation via a process known as capillary action.
This results in excess humidity and moisture which can be absorbed by the insulation. In some instances, excess moisture can lead to visible or invisible mold in the basement.
If a basement suffers water damage it can result in mold which releases pollutants into the air and can keep growing even after the room has dried. This, in turn, will result in a musty smell, especially if the basement has poor ventilation. Unfinished basements also become musty since they usually contain a certain amount of dirt, dust, and debris which can encourage the growth of mold and bacteria. To make matters worse, invisible particulate matter or debris in the air can damage your lungs and enter your bloodstream and are certainly unhealthy.
Other pollutant causes of a musty basement could include things such as fiberglass insulation, dank crawl spaces, Radon gas, and volatile organic compounds such as fertilizer bags and paint cans. If you notice a musty odour from the basement it’s recommended you have the air tested by a mold professional or specialist. Professionals can identify the cause of the moisture and smell and come up with a solution to eliminate it, resulting in a healthier and fresher smelling basement.
The aim is to eliminate the moisture from the basement and increase its airflow. If your basement is unfinished with a dirt floor the floor should be covered with a plastic sheet and wire mesh before covering it with a thin layer of concrete. If the basement has a concrete floor you may need a waterproofing solution if water or moisture is seeping into it. If the basement is filled with mold you may need to have it removed by a professional mold removal company.
If mold is left to grow it could eat through basement insulation, wood framing and other structures and materials. A good ventilation system is also needed as it removes the musty air and replaces it with fresh air. You may need to install an exhaust fan along with a dehumidifier/air purifier and open any windows to increase airflow. If you hire a professional to find and eliminate the source of your musty basement there are a few steps you can take to keep the area as fresh as possible once the job has been completed.
Make sure your downspouts and gutters aren’t clogged as water that pools around your home can start to smell unpleasant. You might also want to send the water further away from your home by installing extensions on the downspouts. This will help keep water from seeping into your basement from the ground near the house. You can also keep the basement air fresh by cleaning it out and throwing away all unneeded items which could absorb moisture, mold and mildew. If the basement is unfinished you can then clean the surfaces with soap and water as well as bleach, white vinegar, or hydrogen peroxide.
Some unpleasant odours can be absorbed by items such as baking soda, white vinegar, zeolite, charcoal bricks, and cat litter. If you place one or a combination of these items in the basement the air should stay fresher. Just be sure to replace them every two or three months. Another option is to place an ionizer downstairs. These devices are designed to remove bad odours by releasing ions in the air. If you plan on hiring a general contractor or a design build contractor to finish your basement, then you must ensure the damp issues are cleared up before installing your drywall and flooring.
But in the long run, it’s going to be difficult to rid your basement of a musty odour if you don’t find the source of it and have it rectified.
