"Landon and Brad came out and inspected my crawl space. I was concerned about my vapor barrier and rightfully so. They took pictures for me (far more detailed than my home inspector), and provided me with a solution and quote. I'll be honest, I don't know much about a lot of this, but they showed me videos of how everything worked and encouraged me to do my research. We even worked on a plan to get everything situated. I like that they understood I wanted something long term, and not just a band-aid fix. I also appreciate them being patient with me while I crunched numbers on my laptop. Overall, the two of them very kind, professional, and informative. Thank you!"

"We were in the middle of moving, we were selling the house that we were in and closing on a new home and there was some moisture found in the basement. This owner was great! We had called other different companies and because of our limited time frame (closing on a house), he was the only one that could come out right away. He treated the walls and waterproofed the lower level wall in the house. By far he was the most affordable company we quoted and he was a very hard work. Honest guy. He gave us a sense that he would not pull one over on you like most companies."

"My crawlspace was wet, moldy, and just nasty. The insulation was soaking wet and it smelled awful. I called five different companies to come out and give me quotes on what they thought needed to be done. I had quotes all over the board ranging from $7,000 all the way up to $48,000. Southern dry was not the cheapest but no where near the most expensive. I decided to use them because Kevin the sales associate I used fully explained the process and broke down each step to where I could understand what was going to be accomplished and what materials would be used. They were even willing to accommodate my special request of adding an extra door to have access under my porch. The installation team, Cha-Chi, Michael, and Ventura were absolutely outstanding. They communicated well and made me fully aware when each step of the process would be taking place. They also always arrived on time and made sure to clean up any trash after each day of work. All in all, SouthernDry is a top notch company with top notch employees to match, would recommend them to anyone."

"This company is owned and run by "old school" professional people who do what they say they will do. Everyone from the office staff to the crew that did the work to the owner Greg McBride were wonderful to work with. I wish I had know about them 4 years ago and I would have used them for everything in and around my home. I trust them and will use them in the future."

"Mason was super easy to work with and was about half the price of the next closest bid from a larger company. As this property was a rental over an hour away, he kept me up to date with pictures at every turn. He went above an beyond to get the job done right. Don't waste your money going with anyone else."

Basement Waterproofing FAQs, answered by experts

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

You don’t always need to install a dehumidifier in your encapsulated crawl space, but it might be a good idea in certain instances. If you notice obvious signs of condensation, mold, or musty smells permeating from your crawl space, a dehumidifier can help. It’s ideal for homes in humid areas.

In a worst case scenario, structural damage like rust on metal beams, rotting wood, and swelling on doors and windows can signal moisture problems that would benefit from a dehumidifier.
