    Basement Wall & Window Area

    I had a basement window blocked up and wanted to seal the outside, before back filling with dirt. I found your product and it looks like just the right stuff. (Before Ordering)

    1. I very much liked the product it was easy to work with and sealed the area I was having issue with. We put it to the real test when Hurricane Florence and Michael came through our area. NO LEAKS!

    2. Ease of application is what I liked most aboutt the product.

    3. I rate you all a 5 out of 5 Excellent product and Excellent customer service.

    Thank you,
