Basement Dehumidification, Because Mold Stinks

Is your basement furnished, comfortable, and the best place to hang out with family and friends? Or is it a dinghy nightmare infested with mold, moisture, and other gross things? Hopefully the former, but if it is the latter then you need to look into effective basement dehumidification technology and techniques. Because you're paying for your home, so you might as well get the most out of it.


Routine basement flooding is an all too commonly occurring problem for many homeowners. Basements that feature an outside entrance, sometimes required by law, are the worst offenders. Heavy rainfall and a clogged drain you don't know about can quickly become a muddy, messy problem.

The solution is maintenance and diligence. A qualified professional can remove clogs and ensure water is flowing smoothly. Your next job is to keep that outside stairwell as clean as possible. It takes fewer leaves than you think during heavy rain to back everything up.


Mold is gross and can be dangerous. Unfortunately, fungus infestations require only moisture and a dark place to grow. And when we talk about basement moisture we aren't necessarily talking about standing water (though that is bad). High humidity is often enough to provide the perfect environment for all kinds of nasty things.

The best way to keep mold from growing out of control is early prevention. If you know you have a moisture problem in your basement, keep an eye out for mold growth. When you see it, clean it up early. Make sure to keep an eye of places you don't see very often like inside closets or crawlspaces. Mold loves those places.

Basement Dehumidification Tools

Dehumidifiers offer the best way to keep humidity low and recover from (non-catastrophic) flooding. Simply put, these systems remove excess moisture from the air. You can set a portable unit up wherever you need it, turn it on, and it works. If you want a permanent and integrated solution, whole-house dehumidifiers built into your HVAC system can do that too. These technologies are not terribly expensive, and they can help you get some actual use out of your basement instead of leaving it as a playground for mold spores and water bugs.

    My basement area is about 1100 square feet. It stays cool during the summer. Would a 9000 BYU unit be enough for the dehumidification?

    It might be, but it would be better to measure dehumidification effectiveness in how many pints per day it will remove. For moderately damp conditions in 1100 sq ft, you're probably looking at something around 15-18 p/day. Get a portable dehumidifier for around $150 or so and you should be fine.
