I've used them before with ok results but this past one sucks. They had been out twice in 2 wks. the original problem still wasn't fixed. When I got home last night I spent an hour cleaning up leftover backup residue. I also spent an hour cleaning up the at least one quart of water still standing under the sink (probably causing mold). Then I went to use the kitchen sink & ran disposal & low & behold the water again came up in the bathroom sink ( 1 sink in each bath - not both sinks). I called again & the man who answered said I would pay double time if they came out last night. I said I not only wasn't paying double, I wasn't paying anything. He said he would talk to the manager in the morning. I said I would just call the BBB. 20 min later I got a call from the plumber & he said he would be back.
He came back & it appeared he finally cleared the problem between the kitchen & the baths. BUT when I went to use my bathroom toilet I stepped in standing water. I used 2 toilet paper rolls to soak up water. And now I hear water under my Pergo flooring. Not Good.
