Crawl Space Problem Signs

Crawl space problems can show up in many ways and might look like foundation issues. Keep an eye out for signs like a musty smell, mold, high humidity, standing water, sagging floors, damaged insulation, pests, and wood rot. These signs mean your crawl space needs help, and ignoring them can lead to bigger, more expensive problems for your home.


If you notice any of these issues, it’s important to call the experts at Ohio Basement Authority right away. We specialize in fixing crawl spaces to make sure your home stays safe, dry, and healthy. Dealing with problems early can save you a lot of trouble and money in the long run, keeping your home’s foundation strong.

Causes of Crawl Space Damage


There are several underlying factors that contribute to crawl space issues in homes. Much like basements, crawl spaces are susceptible to a range of problems stemming from both internal and external sources. Internal factors may include plumbing leaks from pipes that run through the crawl space, malfunctioning HVAC systems, or improper ventilation that leads to excess humidity. Externally, the design of your home’s foundation and the landscape’s drainage system play significant roles in maintaining a dry crawl space. However, the most pervasive issues often arise from the interaction between local soil conditions and weather patterns.

Crawl Space Encapsulation Solutions

Professional crawl space encapsulation is the premier strategy to ensure that your home is safeguarded against moisture, mold, and foundation damage. We offer a range of solutions tailored to address the specific needs of your crawl space. These solutions include high-quality vapor barriers, drainage systems, sump pumps, dehumidifiers, and vent covers. While each component serves a crucial role in maintaining a dry and healthy crawl space, they are designed to operate synergistically as a comprehensive crawl space encapsulation system, effectively eliminating dampness and improving air quality throughout your home.

Implementing this system not only protects the structural integrity of your house but also enhances indoor air quality, contributing to a healthier living environment for you and your family. Moreover, all the solutions we provide come with long-term, nationally recognized, transferable warranties, giving you peace of mind that your investment is protected for years to come.

Julio and his team went above and beyond making sure the basement of a historic church was taken care of better than a newborn to first time parents. The cleanliness, communication and pride of work is totally worth the investment. From Chelsa (sales rep) to the install team, it was a fantastic experience! Thank you!! 🙏

I was really impressed with the quoting experience with Mark! He was friendly, thorough and offered me a few different solutions without feeling "salesy". Unfortunately, the potential foundation repairs were for a home that I was under contract to buy, but had to backout because the seller refused to lower the purchase price to compensate. However, based on the genuine experience with Mark, I'd recommend this company!

Ohio Basement Authority (OBA) installed my inside French drain and I couldn’t be more pleased. The install went quick and smooth. OBA does yearly checks of the system. A pleasant young man named Kyle was the tech today and besides being thorough he was very informative and efficient. All my interactions with employees of OBA was been pleasant and would recommend their services.

Our Inspector, Chelsa, came to our Dayton home the other day to check on some suspected foundation settling. I was extremely impressed with her knowledge, confidence and the way she went about the inspection. She walked the entire house with me, asking questions, making sure she had the layout and all adjacencies correct. After the walk-through, she set up her equipment and showed me specifically where the major problem was located and explained how it would be corrected. When she delivered her full report, it was done very professionally. When I asked her about her company and how she felt about working for them, she replied that she was proud to work for OBA and that she had a great crew working in Dayton. Chelsa also mentioned their parent company Groundworks, and the fact that they are employee owned. (Full disclosure: I'm a big Mike Rowe fan, and heard the Groundworks CEO on his podcast recently). All in all, a very, very good experience.

I had my concrete lifted recently by Ohio Basement Authority. I was very much impressed by the initial inspection and recommendations by Charles. And I was very impressed by the work of the two gentlemen who did the actual lifting. They managed to lift it significantly without cracking the concrete. James and Pedro were outstanding!

Travis came out to the house on time and was super friendly and helpful. Turns out my walls were already fixed and didn’t need to be repaired by then. He was very helpful and letting me know how I could fix it on my own and didn’t need their service. I am very thankful for honest businesses who don’t try and sell you something you don’t need! Thank you Travis!
