I live in the area. I went into their place of business twice. I am a DUIer so I thought I might get help and purchase the materials from them. The first visit was good with the salesman and tech who was there being very helpful There were 10 different seals available. However, I did not have a piece of the seal needing replaced to show to them. So I went home and tried to get a piece of the seal but it was attached to the bottom piece so I took a picture. Not something tht could be slid out and a pice cut off. I saw that it part of the bottom extrusion piece, and not an example of what needed replaced. So I took pictures and returned another day. Unfortunately there was a woman at the front desk who had no smile and was unhelpful, unlike the previous salesman and tech. When I showed her the picture she insisted that I had to cut a piece off although there were already tracks in the bottom piece for a new seal and the old seal was part of the bottom piece. I asked if I could buy an example of what they sell - a small piece. I was told that I could arrange for a tech to visit or cut off an pice and come back. She was unhelpful and had no smile and would not work with me. If you go to the business and she a woman with glasses, turn around and go to Shank Door or some place else unless the saleman or the tech is there. read more
