Basements, by their very nature, are damp environments. Because they are built below ground level, they are surrounded by soil that naturally holds moisture. Even with proper construction techniques and drainage systems, it is not possible to completely prevent moisture from entering the air in your basement. From Outlook Home's standpoint, our obligation is to ensure that there is no pooling or standing water. However, humidity and moisture in the air are normal and unavoidable in any basement.
For the health of your home, it is essential to run a dehumidifier and keep humidity levels below 50%. Excess moisture left unchecked can lead to serious issues, including:
Mold Growth – Mold thrives in damp environments and can begin to grow on surfaces if humidity is too high. Boxes, fabrics, paper, cardboard, wood, etc. placed on basement floors is more susceptible to mold growth.
Damage to Building Materials – Framing lumber, drywall, hardwood, and other finishes can warp, swell, or deteriorate without proper dehumidification.
Air Quality Concerns – High humidity can lead to musty odors and negatively affect the air quality in your home.
For the health of your home it is very important to keep the humidity in your basement under 50%.
We recommend using a dehumidifier with a built-in pump that continuously drains into a proper location, such as a condensate trap tied into your basement’s waste line (equipment included in most of our homes). This setup allows the unit to run automatically and maintain consistent protection for your home without the need for manual emptying.
By keeping your basement’s humidity under control, you are protecting your investment and ensuring a healthy, long-lasting environment for your home.
