Although we had some problems, I was quickly contacted by them when I posted a negative review. And, thanks especially to Dave in the office, all of my concerns have been satisfactorily addressed. It is my understanding that the salesman who created some of our most severe problems is no longer with the firm. Most importantly, up until our treatment by them in November, 2010 we had continual problems in the basement with moisture, and --during torrential rainfalls---water coming in. Since November, 2010 our basement has been totally dry! And that is the bottom line!
