We had a very positive experience with Patterson and especially Mike McGee! We have an old, 1918 home with cast sewer piping that was continuously plugging and eventually backed up. It was an emergency, site unseen project and Mike called us (remote owners) and started explaining the worst case scenario down to the most likely. His estimate was bang on to the most likely. He clearer the old piping, flushed it with hot water, replaced the toilet wax seal and spent 3+ hours making sure everything was right for our 78 year old Mom. Thanks Mike M.! The White’s.
