Three days ago, I noticed some small amount of back up water coming from our main drain in the basement. Every day it seemed to be getting a little worse every time we used water anywhere in the house (shower, sink, dishwasher, toilets, etc.) Fearing a major clog was building that could flood our entire finished basement, I called Mr. Rooter after researching them on line to see the public's reaction to the quality of work and service satisfaction they have delivered in the past. We were happy with what we saw and we felt we had the right place. We were able to get a quick appointment in less than 40 hours (24 hours of that was a holiday anyway) so this was great as we thought we would have to wait a while. "John", the Mr. Rooter service rep arrived right on time at about 9:00am today Apr 4/15 and after a very professional set up and work effort, he was able to clear the line which seemed to be blocked just at the end of where our drain empties into the city line. He used just over 75 feet of rooting cable to finally clear the blockage which puts the block in our view, by that city line area. He was very professional, courteous and helpful to answer our questions about good drainage practices for the future. Recommended that we use their Mr. Rooter (environmentally friendly drain cleaner called BioChoiceES) monthly in our drains to keep pipes flowing well. We purchased a bottle from him to keep things in good order going forward. We were very satisfied with his service and left our house clean from the work that he did for us. We are very pleased and want to thank Mr. Rooter (and of course John) for offering such a professional service to their customers. You turned a possible disaster in to a pleasant outcome......Thanks!We will have no hesitation in using Mr. Rooter again (or recommending them) if we run into any more plumbing problems. Let's hope that not the case! Best regards and thanks again.
