Picture this… sewage water coming up through shower drains and toilet(s) overflowing on Sunday morning of Memorial Day Weekend while you have friends and family over for high school graduation.
Called Comet Plumbing in a panic and explained my situation to which they replied, “Oh no, that is not good… where are you? Got it, on my way NOW hold tight!”
On site within 30 minutes, assessed the situation, provided a reasonable quote, and fixed the issue right away!
I and my extended family and friends were grateful, and graduation weekend was saved!

Andy at Comet Plumbing is the best plumber I've had work on my house. We had an unusual case of needing to clear a blockage where the only access was from a roof vent. Andy was unsure if he would be able to clear it depending on where the problem originated from. He was clear about expectations upfront, and then went out of his way to check the situation with a camera through the various lines. In the end, he believed he could help and went to work. He cleared the blockage and gave recommendations on how to solve the problem long term. He was extremely professional and methodical, and he's a great guy to boot. I'll definitely be calling him back for any future work. Thank… read full review
