It was fantastic. They installed a French drain. They get an A+.
They put in a wall in the basement side. There was definitely water there. They came out to waterproof. I worked with a professional person. I would give them an A+, but they were not perfect.
They did a full perimeter French drain in my basement. I'd give them an A+. It was very clean. I've already recommended them to a couple of people. I liked their knowledge and the products they used for the French drain. When they presented them to me, it was far beyond what the other companies had given me an estimate for. The products they were using were far superior, which sold me on the going with Jamison.
They were great. They were awesome. They waterproofed the basement. They had to dig the outside wall out and put a line in. They were prompt. They were friendly. Everything about it was great. I wish all other contractors could be like that. I'd give them an A+.
I believe we had a sump pump put in. Everything's fine, and it was a nice guy who did it, so we're happy with the job. I'd give them an A+. I would highly recommend them.
Jamison did some waterproofing work. They were very methodical. They were very clean. They did the job beautifully. I have no complaints. I'd give them an A+.
