My kitchen sink drain was blocked solid, sink was full of dirty water... and it was Saturday. I found Thumbtack - never used it before. Entered my problem and Jason was one of four responders and his quote seemed to be great value for a Saturday and I was somewhat sceptical (shouldn't have been!) He had 5 stars and plenty of reviews so I replied to his message and he immediately replied and was at my home within an hour. The blockage was really difficult to shift... in the middle of a very long horizontal drainpipe run. Jason went at it from the sink end, then from the inspection plug end, he used snakes, longer snakes, vacuum, blower... lots of tricks from his obvious experience. He just would not give up! And he is so professional and such a pleasant, respectful and kind person. This job took Jason over two and a half hours and I was fully expecting his price to go up a bit. At one point, about 2 hours in, Jason made it clear that if he didn't fix it, there would be no charge, no call out fee. But he did fix it and when done, Jason charged the originally quoted price and cleaned up with great diligence. I really can't say enough about Jason's character, personality, professionalism and natural understanding of how to provide excellent customer service. My best experience EVER with a service provider of any type at my house. Thank you Jason!!
