Benjamin Basement Waterproofing has a 3.7-star Google rating from 3 ratings. A 2024 customer said the company came out to inspect a water issue in their basement, covered by a lifetime guarantee that came with the purchase of the home, and that he said there was nothing he could do. That customer said they had to hire someone else, and wrote that the lifetime guarantee "isn't worth the paper it's written on." A 2022 reviewer who said they had worked for Mr Benjamin years before wrote that they called him when they needed basement work done and recommended him to their own customers.
Their lifetime guarantee isn't worth the paper it's written on...look elsewhere. They came out to inspect a water issue I was having in my basement (I had a lifetime guarantee that came with the purchase of the home) and he said there was nothing he could do. I had to hire someone else.
I myself have worked for Mr Benjamin years ago then and now his work is top, anytime now when I need basement work done I call Mr Benjamin and I recommend to all of my customers
