Used AI to do some analysis on how much a reasonable sewer repair would cost for a specific style of home, the type of repair, and the relative location of the property. His estimate came in within my estimated parameters. The other two estimates I received from other local plumbers were almost double from what I had anticipated.
Andrew is great to work with. Extremely knowledgeable and provides you with as much detail as you needed to understand the nature of the repair. I would not hesitate to hire him again for any other plumbing projects,

The work was done as planned, on budget, and passed inspection no problem. The work needed was clearly explained. Andrew is a great communicator, he always arrived right when he said he would and he was respectful with his team. His was the lower of two quotes I got for the extensive work needed, and he was always happy to pause and explain what was happening.

I can’t say enough about Andrew and Comet Plumbing. Tree roots had broken into the sewer line causing a backup. I spoke with four different plumbers and Andrew was the only one who didn’t try to add on to the job with extra services such as digging a trench the entire length of my yard and replacing the full sewer line. The PVC line just needed to be repaired and roots removed from one section. Andrew was very honest and did a beautiful job without uprooting my entire yard. His fee was totally reasonable and he was extremely careful with the plants surrounding the area that needed repair. At the same time he was punctual and got the job done quickly and, thankfully, with zero stress to me. He also left the job site clean and neat. The permit was signed off and the work immediately approved by the city with no problems. I highly recommend Andrew and Comet Plumbing.

Great service from Comet Plumbing. He was super busy but still managed to come over the same day I called and do a faucet install. I provided the faucet, but not the hoses - not to worry, Comet had all the parts that were not included. The shut off valve needed replacing, and they had that ready to go as well. Highly recommend.

Andrew from Comet Plumbing was wonderful! He helped install two clean-outs and fixed a root infested pipe for a reasonable price (plus nice discount). I’ll definitely be using them again!
