Humidity, Pests, Allergies & Rot are the most common problems in Crawl Spaces.

One of the biggest issues in the majority of crawlspaces is moisture.

Typically moisture comes up through the ground of the crawl space, especially if that ground is bare. If there are uninsulated pipes or air ducts running through the crawl space, condensation can form on them. If the air outside is very humid, then the vents can actually increase moisture in the space rather than decreasing it.

Too much moisture in your crawl space can lead to all kinds of problems over time. Allergies can develop, the air quality decreases significantly… There really is no better space than a damp, dark crawl space for mold to grow. Dampness can also cause the wood beams of your home to rot and the moisture attracts unwanted guests (like insects and termites).


  • Humid conditions -> moldy conditions. When mold starts growing in your crawlspace, it can be hard to get rid of. High relative humidity (RH) combined with stagnant air can very quickly lead to mold growth on floor joists.

  • Breathing musty crawlspace air. If there is a leak in your duct, your HVAC system might be pulling mold-laden, musty air from your crawlspace into your home, which can happen as well if you have gaps and cracks in your flooring. 


  • Insects like warm, moist environments. There’s a great chance that if you head down to your crawlspace this spring, you will encounter spiders, roaches, or camel crickets, not to mention termites (they love moist wood in crawlspaces).

We always suggest full encapsulation w/ a dehumidification system installed. We offer additional add-ons as well such as sump pumps & reservoirs. The benefits of encapsulating far outweigh the cost!

Bobbi Mattocks

I highly recommend this HVAC company. They are professional and efficient. The technicians who came to repair my unit were Isai Dias and John Carter. Both of them were very personable and knowledgeable about their work. They took the time to fully explain what services they performed and why. I would give them 10 stars!

Teri Lee

Extremely professional, easy to work with, knowledgeable and listened to our concerns. They got our system up and running and advised us on our concerns without "over selling". Once we receive our quote we will have them back to do more updating on our system. Feeling totally comfortable and secure with Butler's. Thank you!!

Stephanie Purdy

Thank you!!
