Basement Dehumidifier

“If Colorado is in a drought, why would I need a dehumidifier in my basement?” While dry weather is a beast for your home to endure, there are still forces at work in your basement that entraps moisture.

The below-ground nature of your basement, condensation on pipes and windows, and expansive soil can raise concern, and put your basement at risk of mold, efflorescence, or pest infestations. All these things can create excessive basement humidity, which not only creates a nasty environment but makes for poor air quality. Learn more about how dehumidifiers work, what sets Peak’s apart from the bunch, and how it can help you and your home.

How the Peak Dehumidifier Works

Dehumidifiers, put simply, draw pints of moisture out of the air in an enclosed space. They’re recommended for use during warmer months of the year to regulate relative humidity levels in your basement. Here’s how dehumidification works:

  1. Dehumidifier draws in moist air through entry point in appliance
  2. Air is cooled within the appliance by a refrigerated coil
  3. Temperature change from warm to cool causes the humidity to liquify
  4. Water drains from the coil into the water tank
  5. Drier air is fanned out on the other side of the appliance to promote desired humidity level in room
  6. Water collected in dehumidifier can be removed by a homeowner manually or will be drained away using a drainage tube to a preferred outlet.

Why Does a Basement Need a Dehumidifier?

Relative humidity is the measure of water vapor in the air, usually given in percentage. In a basement, the recommended relative humidity range should be between 30 and 50 percent. 

Due to drought in most of the state of Colorado, the rest of your home may even be below, or drier, than this range. However, the basement is a little different. Due to it being subsurface, it’s a lot closer to the moisture-absorbent soil and water table than the upper levels of your home. It’s also exposed to piping and ductwork hidden from your main living area.

Signs Your Home Needs This Solution


You might notice piping or ductwork developing condensation, which is a normal occurrence in many homes. But if you see condensation appearing on your ceiling or egress window, there may be a larger issue at hand. Warm air is capable of holding a lot of water vapor. Cold air, not so much. When warm air infiltrates into your basement, the cooler temperature will draw out the water vapor and liquify it again. That’s how you get little droplets of water appearing everywhere in your basement. 

A dehumidifier actively works against this condensation by drawing excess amounts of moisture out of your basement before it can condensate.


Dark, humid environments create the perfect breeding ground for mold and mildew. That’s why mold is commonly spotted in bathrooms and kitchens. Mold can also sprout in your basement if humidity is left to thrive. 

You can spot mold by its fuzzy, splotchy appearance on your walls, ceiling, floor, or even on certain objects around your basement. In some cases, it also gives off a pungent scent that not only smells but can flare up allergies or asthma. A dehumidifier helps to discourage a humid environment ripe for mold growth and promotes better air quality for everyone in the home.


Pests are known to take shelter in homes where they can find dark, wet corners to nest. Your cool basement is no exception, especially during periods of drought. In search of water as a life source, pests like roaches, camel crickets, rats, mice, and other creepy critters can find a home in your basement. 

Just like with mold, a dehumidifier works to create a less inhabitable space for pests to flock to. While it won’t work as pest control, it’s a crucial tool in pest prevention after the exterminators have done their job.


Basement dehumidifiers are worth the cost—just like you’d justify having a humidifier in your home, too. The cost of cleaning out mold or condensation, on top of the potential health risks it could present, is much higher than an investment in a dehumidifier.

A typical rule of thumb for dehumidifiers is to have one that can hold 10 pints of water for every 500 square feet of space. However, consulting with a professional is the one sure way you can get the right size dehumidifier. 

Our trained professionals can inspect your basement to find exactly what’s going on, and let you know what size dehumidifier will work best.

Dehumidifiers won’t dry a basement completely, but in fact, bring it to the appropriate level of relative humidity. The ideal relative humidity level in a home should be between 30 to 50 percent; if your basement is currently above this, a dehumidifier will regulate the humidity levels, and turn on for moisture removal, and auto shut-off when needed. You should keep your dehumidifier off if levels go below 30%.
