Crawl Space and Basement Dehumidifiers in Tennessee

In Tennessee just because you have had a basement waterproofing system or crawl space waterproofing system installed, doesn't mean your basement or crawl space is dry. High relative humidity levels and condensation in the home can still be present, which can lead to mold growth, musty smells, and other problems.

3 things can cause a below-grade environment that doesn't visibly leak water to become damp:

1. Moisture can be brought in by capillary action or wicking. A block wall may not visibly leak water, but it can feel damp because water that may be present in the core of the blocks is wicking to the interior basement wall surface like a sponge.

2. Basement Systems has three basement wall systems to address water vapor permeating through your basement floor and to eliminate any wicking concerns and considerably slows down water vapor transmission into the basement.

3. Exterior air leaking into the basement can contain moisture. The warmer summer air is a concern as it can move lots of moisture into the basement.

A basement (whether it's finished or not) or crawlspace is apt to have a condensation problem whenever the outside air is warmer than the inside air - especially when it's a humid day outside. We know that a house has a "chimney" effect which means air is drawn upwards from the basement or crawl space into the living environment, bringing the moist air into the upstairs area. This air moving from the downstairs to the upstairs can also carry musty, nasty smells, and allergens such as mold spores or dust mite fecal matter (the number one source of home allergens).

When it's a hot and humid day in the summer, rain or not, our crawlspace or basement may be the wettest it has been all year! Even without condensation, high relative humidity levels are present in our homes, allowing mold to grow and dust mites to thrive.


In order to lower indoor relative humidity, water needs to be removed from the air--but removing water in an energy efficient manner is more difficult unless you have the right equipment! Basement Systems and the entire home improvement industry has been dealing with this issue intensely for nearly 20 years. The only machine that will get you the results you need is one called a SaniDry Basement Air System. And it's awesome.

We service in cities like Chattanooga, Knoxville, Nashville, Cleveland, East Ridge, Cookeville of Tennessee.
