Recommended Customer Reviews
Had a plumbing emergency where our sewer/cleanout was backed up and causing glugging in the household toilets when flushing as well as the showers to back up.
Called and got an immediate, calm (appreciated in a shitty situation like this) response from Andrew who said he'd be here within an hour.
Andrew came and fixed the problem immediately and fed a camera through the pipe to see what caused the blockage. He also gave me a thorough understanding of my sewer situation which was much appreciated - infinitely better service than previous plumbers I've worked with to solve this in the past. All at a reasonable price, I'm grateful for the impromptu save on a Sunday.
Ben H.We had just moved to our new place and the sewer lines kept backing up. We called Andrew at Comet who came with recommendations from multiple neighbors. He and his team were caring, meticulous, trustworthy and very professional.
They ended up fixing the pipes on the property and putting in a new clean-out with all the permits. Then we found out that there was collapsed pipes beyond our property line into the middle of the street. He got in touch with the city immediately and got them involved to fix their end of the issue which was very helpful, because some cities put the burden on the homeowner to fix that. All in all, a great experience. I would highly recommend them and would certainly use their services again.
Andrew (Comet Plumbing) did all of the re-piping for half of my family's house. He also replaced faucets, put in new valves, etc. Great job. Very professional.
Comet Plumbing (Andrew) was responsive and on time, price quoted was on point. The job was completed and am very satisfied with the overall service and will be using Comet Plumbing for all future needs.
I would highly recommend Andrew and his company to anyone in need of a plumbing problem.
We have had Comet Plumbing work on several jobs over the years. Andrew and his crew are always professional, informative, punctual, and reasonable. Quality and timely work, and our go-to for any future issues.
I've never had any responsiveness or communication concerns. Text or call the 408, or call the 800 number.
While they seem to have good reviews and came recommended by neighbors, they were totally unresponsive to my phone message and request for quote through their website. I don't mind that service companies may be too busy for my job (or that it may not be big enough for them), but I appreciate and expect the courtesy of a response. I wasted a week waiting to hear back, before moving onto another highly recommended company that were incredibly responsive.
Vanessa B.I called Andrew at 7:30am this Sunday morning and by 11am he was out here with our sewer blockage problem. Reasonably priced and he worked really hard to resolve our draining issue. We were all worried for a moment but so glad Andrew kept working at it and tried different outlets until our tub started draining again. Thank you so so much!!
I called Andy from Comet plumbing for changing a part of the sewage line which was getting clogged by Tree roots. They gave the best quote for the job. They were fast, efficient, took care of the city permits, and did a good quality job. My problem is fixed permanently now.
Ronda G.We are very pleased with the service we received from Comet Plumbing to replace our sewer line. Comet had been recommended by a number of people on NextDoor, so I contacted them for an estimate. Andrew responded quickly, and of the three estimates I received, his was the best price. I also felt comfortable that he understood the job he was quoting, where I didn't have that confidence in one of the other vendors. He was able to do the work quickly and actively followed up through final inspection.
I was impressed with Andrew's work ethic, diligence and honesty throughout this whole process. I will be calling him again for future work, and I highly recommend his service.
I contacted Comet and Andrew responded very promptly. I needed my sewer line checked out with a camera to see if it needed replacement. I also wanted the drain in the garage sink checked out as well. Andrew gave me a quote over the phone and we fixed a time and he showed up promptly. He ran the camera and gave me very practical advice on next steps and followed it up with a quote the next day! He also jetted out my sewer line to clean out what he could. He also checked out the garage drain and informed me that he thought it was running fine and did not need to be rooted. Very satisfied with his service and would highly recommend him for your plumbing needs.
