"We have been happy with the waterproofing that was performed by Everdry of Toledo. We did have a few issues once the job was completed, but after calling in and discussing the issues, they were able to send technicians back to our house and the problems have been resolved. We have now been dry since 2014. Thanks from JRN Bryan, Oh."

"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."

"I’m a custom home builder, and we also do high end remodeling. I have Blake Micheal Construction do my foundation and waterproofing work, as well all my concrete needs on my new homes. Eric and his crew are very efficient and hard working. Eric is knowledgeable and honest. I would definitely recommend him."

"Here to remove large tree branches that damaged my roof. They arrived the morning after the storm to tarp my roof and remove the branches. The repair was completed the next week. Garage looks great, very satisfied with project. They communicated with my insurance to help me get coverage for the damage. My yard was cleaned up after they finished. I would recommend this company 100%, great job"

Basement Waterproofing FAQs, answered by experts

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn’t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn’t have any more issues than a slab or basement home.

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.

Yes. Water can penetrate through a concrete foundation wall. This can happen whether or not you have cracks, as concrete is a porous material. You’ll want to take steps to waterproof your basement or crawl space.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.
