Zwierzynski Waterproofing

After 5 bad basement leaks over 10 years we were lucky to get John. He was incredible in his diagnostics and thorough and patient and fixed several major issues in our basement He worked on the inside and outside Thank you John I will certainly recommend him to all my friends and feel fortunate to have competent and honest professionals like him work on my premises

John is very kind and professional. He added supports to my Michigan basement and went above and beyond. He made more repairs than what was in the estimate, but kept the cost the same. I definitely will be calling Zwierzynski Waterproofing again as needed!

I have an old Michigan basement with a stone foundation that was needing some repair work done to make it more solid. They came, took care of it, did more than I thought I was going to get and left the area very clean. All for less money than I had been told by other companies it would cost.

We called Zwierzynski Waterproofing to do some crawlspace waterproofing on our home. John finished the project quickly and the quality of work shows! We will always call Zwierzynski Waterproofing for our waterproofing needs!

We have recommended him many times over the years, and he always provides prompt, reliable, and efficient service. Our clients have been very pleased!
