"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 am amazed at The quality of their customer service. Before I became disabled, I was employed at the hospital for 28 years and I know how hard-working with the public can be. I really need to give a hats off and a pat on the back to (midstate Basement) systems they came in and did work on my basement and had to come back and adjust some things… Not one time did they roll their eyes or give me a hard way to go about it. Levi ,Judd, Ernest, Jonathan & Adrian were very friendly, courteous & Ernest, Levi and Judd always answered any question I give them and was quick to be of help and to get me scheduled in I would highly recommend Midstate Basements systems to anybody that needs any kind of basement or crawlspace work done. I had my basement done and I’m gonna have to have my crawlspace done in the future and they will definitely be the company I contact. You can’t go wrong by hiring them. Fast, friendly service, each and every time."

"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 are great to work with. Communication was superior. They stand by their work. A few years ago I had waterproofing done in my basement and this time they spray foamed the cavities of the basement too. Both times they did awesome work and cleaned up too! I highly recommend this company!"

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.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.
