What to Know About Vented vs. Unvented Crawl Spaces in the Nashville, TN, Climate

Crawl spaces are often overlooked but play a crucial role in the health and energy efficiency of your home or business. Your crawl space can become damp and musty over time, or even be a source of mold and mildew growth, impacting indoor air quality.

It’s why knowing the difference between vented vs. unvented crawl spaces is key and where Complete Insulation comes in. We specialize in tailor-made crawl space systems for homeowners and business owners across the Nashville, Tennessee, area, keeping properties dry, healthy, and more energy-efficient.

Understanding Vented vs. Unvented Crawl Spaces

Vented crawl spaces allow outside air to circulate beneath the house. In some climates, this can help control moisture and improve air quality.

However, in humid areas like Nashville and Middle Tennessee, vented crawl spaces lead to moisture buildup. This often causes mold growth, leads to poor indoor air quality, and can even result in structural damage.

An unvented crawl space, on the other hand, is sealed from outside air. This not only improves energy efficiency but also enhances indoor air quality while protecting your property’s structure.

Our Crawl Space Encapsulation Process

If you have a vented crawl space and want to convert it into an unvented one, Complete Insulation can help with our crawl space encapsulation services. We’ll insulate the perimeter walls and install a TRU-Encap vapor barrier to protect against moisture intrusion. This process not only enhances energy efficiency but also improves and maintains excellent air quality and safeguards your property’s structural integrity.

“I had a fire in my attic and needed all of the contaminated insulation removed. I am *AMAZED* at how thorough the hard working folks at Complete were. You could almost eat off the floor of the attic. The entire crew was courteous, quick and more than fair with the price. Highly recommend.”

“The team who came from Murfreesboro, TN to our house in Chattanooga were amazing. We have a very large home. They removed all the old insulation from our three attics, sprayed with a decontaminate and then sprayed all the new insulation. All in one very long day. They were great to work with, came went they said they would, answered all our questions. Had to put the tubes all the way from the attic down to the first floor and out to the truck. They covered all the floors, stairs etc and left the place spotless. We are very pleased and would highly recommend this company.”

“I was building my own custom home and "interviewed" several spray foam insulators. It was clear Moody Ozier had a deeper knowledge of air sealing, R-value, and building codes than anyone else, so I went with Complete Insulation. He really took an interest in my hyper efficient build and came up with additional engineering ideas to further improve the efficiency of my home. I cannot say enough good things about Moody and Id tell anyone he's trustworthy, efficient, and knows the insulation and air sealing business to great depth. Jose, Fredy, and their crews showed up on time, in uniforms, with clean trucks and did a wonderful job on instal AND cleanup. They were incredibly professional at every step and it was clear they had years of experience. I recommend Complete Insulation to anyone with encapsulation and/or insulation needs whether you are new construction, retro fit, investor, or otherwise.”
