For over four decades, Ohio State Waterproofing has been the basement waterproofing company Ohio families trust most. What started as a small family business in Macedonia has grown into N.E. Ohio’s leading waterproofing and foundation repair company, with over 90,000 satisfied customers who chose local expertise over out-of-state chains.
When you choose Ohio State Waterproofing, you’re not just hiring a contractor — you’re partnering with neighbors who’ve been solving basement problems in your community since 1978.







In 1978, Nick DiCello started Ohio State Waterproofing with just $200 after his previous employer abruptly closed. Instead of walking away, he stepped up - recruiting key employees and making sure local vendors received what they were owed from the previous company. That commitment to integrity set the foundation for everything Ohio State Waterproofing would become.
Under Nick's leadership, Ohio State Waterproofing patented its Multi-Step waterproofing system in 1984 - still the only system on the market that attacks water issues from inside and outside. The company has since installed over 90,000 successful waterproofing and foundation repair systems, earning Nick the prestigious Ernst & Young Entrepreneur of the Year award in 2009.
What truly sets Nick apart is how he leads. Many of the original employees he hired in 1978 are still with the company today. Beyond business, he's known throughout the community as "St. Nick" - personally shopping, wrapping, and delivering holiday gifts to foster children at Beech Brook for over 25 years.
“You love what you do and you believe in what you do. It’s not a bad place to work.”

Well I wasn’t sure I was going to proceed with anything at my initial meeting since my basement had only some seepage over the years. But upon meeting Jordan my decision was made after his visit. He showed me things I never would have noticed on my own that are problematic. I thought I could do a simple fix. He thoroughly explained how water seepage occurs and how things can worsen in the future. I did not feel pressured at all and I felt he answered all my questions and definitely educated me on how water finds its way in. He was educated and courteous and I felt very sincere. We talked about different ways to fix the problem and in the end..he got me the best possible solution with the best possible financing. He took time to make sure I was comfortable with my decision and I definitely am! I am confident he will insure the job is done to my satisfaction. Thanks Jordan!Posted on Dec CookTrustindex verifies that the original source of the review is Google. Very thorough estimate.
