Third experience with Mammoth. Timely, personable, efficient, and job done properly first time. As a new homeowner with several plumbing issues that have come up, it’s been great to find a reliable option. Not to mention the OUTSTANDING price. Keep up the good work, glad I have a go to and can mark plumbing issues off my list of concerns.

I am 71 years young and finding a plumber is very scary. I found Mammoth Plumbing on Thumbtack and had them install a toilet for me on 10-16-2025. From the very onset, it was a very pleasant experience. mammoth devoted time to scheduling an appointment that fit my schedule, and their plumbers were outstanding. They were very professional, skilled, polite, courteous, and went above and beyond the call of duty to make sure I was completely satisfied before they left. They even took the time to shower my Husky, (Kita) in some attention and she loved it. If you are in need of a plumber, look no further than Mammoth Plumber. They are reasonably priced compared to other plumbers in the area and they do a great job, and by the way--thanks again Matt for a job well done. You have definitely won my business.

Absolutely outstanding service! This plumbing company has been incredible from start to finish—prompt, professional, and extremely detail-oriented. They explained everything clearly, and made sure the job was done right the first time. It’s rare to find a contractor this reliable and thorough. Highly recommended to anyone looking for trustworthy, top-notch plumbing service!

The team at Mammoth Plumbing was exceptional! They got our for our quote quickly. Every step of the way was very professional and even the owner reached out to make sure my husband and I understood the whole process. We had a main line backup. We needed 64 feet of clay pipe lined. This was a HUGE job! We had other quotes but we ended up going with Mammoth because their owner was so wonderful. This was already a very stressful event and the team at Mammoth Plumbing made it seem manageable. To top it off they sent us cookies as a thank you! I highly recommend!

(TLTR: They're awesome!) Over the holidays, we had several guests. While one set of guests were here on Sunday (with another set due to arrive Monday), we replaced the garbage disposal and what ensued was complete and total chaos. I am unsure how replacing a disposal backed up three sinks, but we managed to do it. How? I can only conclude that the house hates us and was taking its revenge. Thank goodness we were able to get in contact with Mammoth Plumbing, who really saved our heinies. The owner and the plumbers were all excellent in the service they provided. After messaging them Sunday night, Mammoth was able to come Monday knowing that we were under a time crunch and they were very busy with the holiday rush. They addressed anything that came up quickly and effectively as the situation evolved. As they assessed the situation, and even as things changed, they responded with patience, professionalism, attentiveness, and flexibility. They also charged a fair price. They sent three separate people to address three separate issues as they arose (nothing that was their fault, it's just what the situation called for), and with 30 minutes to spare before our last guests arrived on Monday evening, they finished and we were able to be ready. I am pleased with our experience with Mammoth and would not hesitate to call them again. Thanks for being one of Santa's elves, Mammoth!

We had a water line break between the street and our home. Mammoth Plumbing took care of all needed calls to make sure all other lines/cables were flagged. Once on-site, they worked quickly and efficiently to get a new line installed. The workers were knowledgeable and efficient. The clean up of the yard after was also appreciated. I would 100% recommend you "Trust the Tusk" with Mammoth 🦣 Plumbing.

This was our first experience with Mammoth Plumbing. Taylor and Matthew initially came out as a second opinion for basement drain backup issue. They gave a good explanation of the problem and did an excellent job making the appropriate repairs at a more reasonable price than the initial estimate Colin joined them with the repairs and they did a great job and cleaned up well after they were done. Matt, the owner, was very easy to communicate with and did a great job of returning calls when there were questions. We would definitely recommend Mammoth plumbing for any plumbing needs.

The plumbing company contacted me immediately after I submitted my request through Thumbtack, which I really appreciated. They provided a clear quote upfront for the service I needed, so there were no surprises. They arrived on time and completed the job efficiently and professionally. Taylor did an awesome job explaining the issue and what needed to be done to resolve it. She was knowledgeable, thorough, and made sure I understood everything. I highly recommend them to anyone needing reliable plumbing services.
