Review 1
Great team , 3 seperate crews but all very professional. Work was exceptional and clean up too !! Basement walls look great. Had a storm a few days after completion and no leaks ! Very very happy . Finally walk around with Anderson was very informative. Glad I chose Zavza Seal , their previous reviews helped make my decision. Admin was smooth too…. would use again and recommendations to all. Thanks , great company.

Review 2
I have had a water issue coming into the house, and called Zavza Seal. They came and looked explained where the water was probably coming from, then told me everything they wanted to do to mitigate the problem. We then decided to use Zavza Seal, we are glad we did.
They were very professional, did everything that was written into the contract exceeding my expectations. I would highly recommend this outfit.
Zavza just finished the job and we haven’t had significant rain to test the fix just yet, but I will follow up with a review again when we do. Zavza Seal keep up the good work. Charlie Zachman
