My first floor master bedroom french doors had been leaking for months whenever we got a heavy rain and would saturate the lower level guest room walls and flooring. We called A Plus Waterproofing and they quickly discovered the problem which helped our contractor make repairs. I found Michael to be knowledgeable, professional, and would absolutely call him in the future. I highly recommend

Michael and his team responded to our call quickly. The basement walls were cracked and water was leaking in. A Plus Waterproofing used an amazing waterproofing material to make the repairs. They left the basement clean and the workmanship was the best!

After dealing with an outdoor water issue for years that created foundation problems I contacted A Plus Waterproofing. They resolved the water flow issue with a pop up drain and diverted the water, These guys went above and beyond what I expected. Neat and organized!

About Us

Michael De La Blanc

Apprenticing for my Dad at the age of thirteen is one of my fondest memories, but even before that I can remember watching him work all the time. My grandfather established our company in Lexington, Kentucky back when we specialized in waterlines and construction. Always wanting to learn more and add to the family legacy, I picked up new trades that expanded our business into waterproofing after moving to Louisville. Waterproofing has become my specialty and nothing pleases me more than resolving waterproofing issues within someones home or business. Honesty, integrity and customer satisfaction are the cornerstones of A Plus Waterproofing. Our team is knowledgeable and ready to work diligently on each project with pride.
