9 Tips for Preventing Mildew in Basement Storage

Basement storage is a great way of using space efficiently, provided your basement is free of moisture problems. Storing seasonal items and rarely used articles or prized possessions in the basement can free up a lot of space upstairs, where the family spends most of their time. However, it is an unfortunate fact that the basement is an area that is most prone to water retention, moisture accumulation and excessive humidity, all of which contribute to mold and mildew growth. There is a lot you can do to prevent these problems and save your stored possessions from damage.

1 – Use Plastic or Metal Cabinets for Storage

Wooden shelves are not the best choice for basement storage, because of wood’s tendency to absorb and retain moisture. Similarly, cardboard containers are also not a great option for long term basement storage. Use metal storage shelves or plastic bins with lids to store your belongings, as these materials are largely impervious to moisture.

2 – Allow Stored Items Access to Air

Always ensure that your stored articles in the basement have some air circulation. This is important to prevent musty odors and mildew from forming. Always ensure that your clothes are clean before you put them away for storage.

3 – Check Stored Items Often

Never leave your stored items unattended for long periods of time. Make it a point to check your belongings once in a while. When the weather is favorable, leave the items outside in the sun for some time.

4 – Use a Mildew Inhibitor

Mildew inhibitors are chemicals that prevent the formation of mildew. Some materials such as leather are more prone to mildew growth, and must be stored with a mildew inhibitor. Never store damp clothing or articles. Ensure that all the items you store are thoroughly dry. Also avoid starching any garments that are going to basement storage.

5 – Repair Cracks in the Foundation

Basement leaks can be caused due to water retention and cracks in the floors or walls. Look for signs of wetness on the walls or on the floor, and take prompt action to fix these issues. Look for cracks or holes in the foundation and repair them as soon as possible. You can cover small cracks inside the basement with cement. Applying a waterproof paint on the basement walls will also provide better protection against moisture.

6 – Clear Clogged Gutters and Downspouts

Check your gutters and downspouts regularly for signs of clogging or blockage. Clear all leaves, debris and dirt to enable the water to flow freely, thereby preventing accumulation around the foundation.

7 – Insulate Water Pipes in the Basement

Insulating water pipes is a great way of preventing condensation problems, which can greatly increase the humidity level in the basement.

8 – Promote Ventilation

Whenever possible, open the windows in your basement to let in some fresh air and sunlight. This is a great way of airing out the basement, and also reducing the chances of mildew growth.

9 – Use a Dehumidifier

A dehumidifier is a requirement in every basement that shows any signs of moisture accumulation. Make sure that all doors and windows in the basement are closed when you operate the dehumidifier.
