"My mothers kitchen drain was completely clogged and we couldn't get it open. We called Jon's and they had someone here the next day. Drew was great and was able to get it unclogged, after a bit of work. Nice guy, professional, and cleaned up after he finished. Mom was happy..... and that's hard to do. :)"... more
