I have been using Johnsons Carpet Cleaning for about twenty years and have never had a bad experience. I call them to clean the carpets in my home about once every six months. I also use their snow removal services in the winter. And now, in the summer, they provide lawn and landscape services for me. In my experience, all of their service people have been very friendly and very knowledgeable. I've found them to be a very reliable company.
