“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+.”

“Jamison actually did a couple of jobs. They patched my chimney a couple of months ago, and then last fall, I think it was, they waterproofed the basement. It was more like a water mitigation. They changed the windows out. They put Drylok on the unfinished walls and cleaned up a crawlspace area. They were very prompt, timely, and they were not messy. I would say it was an A+. I already have recommended them.”
“They finished the job that a contractor had started and had done poorly, so they came in, and they parched and painted the walls, sealed up some things, installed some lights, and I think that's it. They were efficient, professional, did what they said they were going to do, and were really pleasant. I'd give them an A+. They were great.”
“It was a good experience. They had done some concrete work on a previous home leak we had. They were very friendly, open, and honest about all the work they were going to do. And they discovered some other stuff that they went ahead and fixed without going through and charging us again. I'd give them an A+.”
“They waterproofed two crawlspaces in the house. It was a good crew. They came in, got the job done in one day, and then they were gone. I'd give them an A+.”
“They waterproofed and insulated the basement. They left the jobsite clean, they did what they said they were going to do, and it was done quickly. So far, so good. I have no complaints. I don't really have anything to compare it to, so I'll give them an A+. I don't know if they could have done anything else.”
“They were doing a French drain. They did what they said they were going to do and, knock on wood, but it seems to have worked. I'd give them an A+.”

“They did a sump pump installation. It was just a console originally, and then we landed on a new sump pump in the basement and some exterior work to push the excess drainage away from the house. I'd say they're an A+.”
“They were great. We just had water periodically in the basement, so we had it done. It was definitely an A+. Their customer service was great. I can't say anything bad about them. We have recommended them to other people. We had one problem, and I called, and they were here the next day.”

It was very timely, it took care of my problem, and if anything arose, they came out and addressed it immediately, so they have done a really great job with it.”
“They were great. I'd give them five stars out of five. It was waterproofing work. I'd give them an A+. They were responsive to my needs, which were immediate. They came, they determined what was needed, gave me a quote, and they did the work very professionally. The two men that came were very professional, and it was completed within two days of the quote. I was very happy with their whole operation, and they checked back with me to make sure everything was alright.”
“It was a very positive experience. They did full basement waterproofing. What I thought was going to be a very long, drawn out, and dirty process went very smoothly and cleanly, and the guys are really knowledgeable that did it. They definitely were an A+. I thought they were great all across the board. I really have no complaints whatsoever on it. Either the company or the people that came in to do the work. I would absolutely recommend them.”
“They were very professional and very efficient. They were installing a battery back-up pump. They were just really good. They were there when they were supposed to be. The work was done, and they cleaned up when they were finished, so it was all good. It was all good. I'd definitely give them an A+.”

When there was a little hiccup in the process, I left him alone, and he corrected it right away. The fellows that were here were polite and nice. At the end of the job, it was better than we could have imagined. It was a really nice job. Overall, I'd give them an A+. I would definitely recommend them to other folks.”
“They put a perimeter drain around the inside, and then they put two sump pumps in. They were very professional. They broke up the concrete and had to haul it up the basement stairs. They were professional. They were courteous and did a good job; and so far everything's worked well. I'd give them an A+.”
“They were here waterproofing our basement. They installed a French drain. They were very kind, thorough, and very friendly. That's about it. I would definitely give them an A+.”
