"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."

"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."

"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."

Basement Waterproofing questions, answered by experts

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

If not properly maintained, an underground downspout may damage your home's foundation. A clogged downspout can back up, causing water to pool around the base of your home and seep into the foundation. Regular inspections and maintenance keep your downspout in good working order, preventing damage and protecting your home.

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.
