Crawlspace Dehumidification Nashville

In a high humidity climate, additional dehumidification steps are often necessary to manage humidity levels in your crawlspace and prevent mold growth. 

Crawlspace Humidity Control

We don’t need to tell you that high humidity in your crawlspace is a recipe for problems. High humidity in combination with a high dew point leads to condensation, and that condensation fosters mold growth. But managing humidity in your crawlspace is possible.

The most reliable way to control the relative humidity in a crawlspace is to seal the crawlspace with a high-quality vapor barrier, seal the foundation vents and any other openings to the outside, then install a properly sized dehumidifier with a dehumidistat that maintains a relative humidity of around 50% Rh. We can help you find the solution that works best for your property.

How Do You Reduce Humidity In a Crawlspace?

The first step towards reducing humidity in a crawlspace is to limit the amount of moisture entering the crawlspace. A high-quality vapor barrier is the first step, followed by sealing the crawlspace vents to create a conditioned space. A dehumidifier is installed in the crawlspace to maintain a constant relative humidity level in the space. Fans may also be necessary to help circulate the air to the dehumidifier.

An automatic condensate pump that pumps out the condensate so you don’t have to dump a bucket is a must. A remote sensor can allow you to monitor the temperature and relative humidity so you don’t have to crawl under your house to make sure everything is working properly. The upside is that it will work if it is properly sized. The downside is that it is a piece of equipment, much like your air conditioner, that will require a little maintenance. 

Do I need a crawlspace dehumidifier?

Should you open your foundation vents in the summer or winter? What would happen in the abandoned house in the example above if you opened the windows during the summer? Do you think that would improve the situation? Of course not! I guarantee you all the drywall in the ceilings upstairs would grow mold. 

So how is a crawlspace different? The truth is, it isn’t. What’s worse is that there are usually ducts in the humid crawlspace that sweat due to condensation. When that condensation evaporates it raises the humidity even more. The wood subfloor absorbs the water in the elevated humidity climate and the high dew point reaches the temperature of the wood and condenses directly on the wood. Both conditions create a wood moisture content level that supports mold growth.

What People Are Saying About Us

Derrick Miller

TOP notch folks. Called and got an immediate response. I called them in a hurry and they showed up the next morning to do a mold test. Very helpful and professional and I will use them again!!!

Rosaline Sweat

I had nothing but a wonderful experience with Tier. They were on time,very friendly and knew exactly what they were doing. I had a spot that I'd had for 4 year on my carpet and figured I would have to replace that carpet but they got it out after a couple of tries. I was truly amazed. Alex, the manager, I'd worked with before and I can't say enough good things about him. He's always there when you need him with a solution for whatever your problem is. He has a very positive attitude and is great to be around. All in all my experience was fantastic!

Josh Morris

I honestly believe you won't find a better company to work on your home than TIER. Alex has always given me more than fair estimates and exceeded all my expectations with the final product.

Most recently, TIER installed an interior french drain in my house. Alex came out to my house through all stages of the project. He even did a final walk through and decided that he was not satisfied yet and told me he would send his guys out to bring it to his standards. I can't stress how rare this is.

Until working with Alex and TIER, I had not found a company in Nashville that I trusted. They are the only company in Nashville I would feel comfortable recommending to a friend.

Greg Lewis Tier Restoration is committed to doing the best work. The company's slogan, “Experience The Next Level” really describes Greg's work ethic as a professional in his field. He is a great resource for folks who need help with their homes. Greg and his team are folks to be trusted!

Monte Mohr

I've been selling homes for over 30 years and have owned rental properties for over 10 years. Tier Restoration is by far the best company of its kind I have ever used. As a real estate Broker selling hundreds of homes a year it is empowering to have a company as competent and professional as Greg Lewis and his crews. As a landlord I have personally used them twice in the past 12 months on major situations. The kind of challenges that would cause many to lose sleep over. In both cases Alex took my fear and concerns I was facing and extinguished them all by his consistent timely communication and professional awareness throughout the process to completion.
From simple duct cleaning to major foundation and crawl space repair and remediation there is only 1 company that I call. They are simply the best!

The Evans Family

The Tier group were amazing!! From the moment they walked in my front door, I knew we were going to be in good hands. The work was professionally done, and the communication was outstanding. Don't waste your time looking at other restoration companies, choose Tier and have that peace of mind that we had!!

Tracy Snow

Alex and his team are amazing to work with. Everyone is courteous, on time, and thorough in their work. Alex stops by to personally check on his crew and talk with the homeowner. I highly recommend Tier Restoration and will certainly use them again and again.
