I had issues with one of my toilets. I sent 4 messages out on yelp. Discount drain responded first, and one of the most professionally. They called me, as requested but then I got distracted with life. Three weeks later, the day before thanksgiving my kitchen sink starts to back up. I send a text asking about availability for both issues. They knew who I was, and even had my information at the ready. They came right away, no emergency charge or anything.
They were polite, friendly, and professional. For my toilet they explained how I could do it myself before telling me what they would charge if I wanted their help For the kitchen sink they had to use some fancy tools, and charged me comparable to what some other yelp responses had quoted for a clog.
I am very happy with these guys, and will be using them for all of my future plumbing needs!
