"We had a crack in our poured concrete foundation. We had estimates from other companies that involved waterproofing the entire lower level (it was already waterproofed) at very high prices without even addressing the crack. Eco-Seal Home Solutions addressed the problem we needed fixed, gave us a fair price, and completed the work in just a few hours. We will call them again if we have any other foundation cracks. Great work."

"In November 2024 we hired Interstate Systems, Inc., located in West Salem, OH to repair and waterproof the water damage in our basement. The men working on the job were exceptional. We watched them work extremely hard for three days straight. When the work was complete, my husband and I could not have been happier. It was a pleasure to work with their President, Mr. David Nagel. Mr. Nagel took his time to explain everything clearly so we would understand exactly what the project entailed. We thank the entire crew for helping us solve a major problem. Jim and Kimberly M."

"I wish I had hired them first! I hired another company to fix my moving bowed and shearing basement walls. They were primarily a waterproofing company, but said they had the solutions to my issues. 3 months after they were complete, my walls cracked and shifted again. (Note, in the attached photos, the patchwork quilt on the walls was the OTHER company.) OBA fixed my issues the correct way. And they were great at every step. The work crew Caleb, Delontae, and Dylan were fast, efficient, and cleaned up when they were done. Caleb made sure to explain what was happening as they did the work and ask if I had questions. The work was thorough, and I feel good about it. And even better, they'll be out in 6 months to ensure everything is working as it should and make adjustments if needed."

"They did an awesome job! They did great work in a week. You cant even tell where they had taken the floor out to work underneath, it was put back together perfectly. They fixed the joists and beams under the floor. They went the extra mile to make everything look great at the end. I would highly recommend them."

"Guys were very likable. They respected our home and left the space ad they had found it. Will have to wait for the weather to see if the chimney flashing seal is finally sealed correctly. As it had been done by someone else prior to this."

Basement Waterproofing questions, answered by experts

No, you don’t want your crawl space to be wet because water and even moisture in the air under your home can attract insects and rodents, decrease your indoor air quality, increase your energy bills, promote mold growth, and even lead to structural damage. If you notice any signs of water or humidity in your crawl space, you should get the issues addressed immediately by contacting a professional. They can remove moisture and will know how to waterproof your basement to prevent ongoing problems.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.
