I utilized him, Paul, about 3 years ago for a termite problem.  I picked him based on Yelp reviews.  He did the treatment and then had to come back to retreat about 4 months after the original application.  I called him on the phone and he said he would come back but he was not going to make anything since it was under warranty.  When he came to the house again he made it very clear that this was costing him money because it was all under warranty.  I have never experienced having a business owner try to make me feel bad for asking them to honor their warranty, a warranty that I paid extra for.  I will never utilize his services again.
