My experience with them was very good. They were very professional. They were very knowledgeable about what was happening in my house and about the issue that we were having. They didn't try to get us to spend needless amount on items that were not going to do anything different. We had someone come earlier and they were charging arm and leg for the job. But the gentleman from Basement Systems came and checked everything out.He had a computer with him and he pulled out everything and explained all the stuff for about two and half hours. He seemed to be pretty relaxed. I thought that it was expensive but it was fine for what we got.
