Indoor Humidity Control

Humidity Reduction

Radon mitigation systems can be a solution for indoor humidity control. Because sub-slab depressurization systems remove soil gasses from under the floor, they also remove large amounts of water vapor that could otherwise enter the basement or crawlspace. A radon mitigation system can dramatically help effect the dampness, the smell, and the mold susceptibility of those areas.

DuPage Radon Contractors have experience installing systems for the primary purpose of indoor humidity control in a lower level.

Benefits of Humidity Control in Your Home

Moisture control is important because it protects the building and its occupants. Prolonged damp conditions can cause wooden materials such as furniture, walls, and decor to swell, warp, or rot. It also damages varnish, paints, and brick (during freeze-thaw cycles). Too much humidity can lead to mold growth, efflorescence (a white corrosive action on masonry) and corrosion of other building materialssuch as wiring and air conditioning coils. While portable or central dehumidifiers are a possible approach to controlling moisture, they are much more expensive in electricity and louder  than a “radon” system.  These sub-slab depressurization systems suction the moist soil gas out from under the floor before it even gets into the home.  They then send the moist air outside up high away from the home. 

Get an efficient dehumidification system to save money and increase comfort levels. Household members susceptible to allergies and other respiratory illnesses can also benefit from it. 

Controlled humidity levels can also:

  • Safeguard electronic devices 
  • Protects  home furnishings
  • Alleviates allergy symptoms

Advantages over dehumidifiers:

  • Much quieter 
  • Much less expensive to operate
  • Highly durable

Many radon mitigation customers have, over the years, indicated that they no longer need to use their basement dehumidifiers, or that the musty smell in the basement or crawlspace is gone. The radon system was acting as an indoor humidity control system.

EPA Sees Same Effect

A preliminary study by the EPA saw a dramatic dehumidification effect from the installation of a radon system. In their study, an average of 13-19 gallons a day of water was removed in their test. While your results may vary significantly, their results were significantly more humidity than is removed by an average portable dehumidifier.

Radon mitigation systems may cost more up front than dehumidifiers. However, they use much less electricity over the long term. They also are a quieter method of indoor humidity control, and are usually less conspicuous.

Subsoil situations vary and no specific humidity levels are guaranteed.
