I had called a different company that charged a big service fee and did nothing to fix the problem. However Mammoth came out fast and on time and readjusted the work I had done and got the water heater started in 10 min. Michael was great. I will used them before anyone else in the future. Awesome company!

Excellent service! We used Mammoth at our previous home as well, and just had a new water softener installed on our new home due to our extremely hard water. Jon is always direct and I explains the situation well. Punctual on service calls, and informative with his diagnosis. We also use Mammoth for all of our customer’s needs with gas lines in the home and for whole home Generac generators. Reliable, dependable, honest 👍🏽 If you’re looking for a dependable plumbing company that stands behinds their work, you’ve found them!

Jon and Jay arrived at my home to help move some unexpected pipes that were enduring a renovation project we are working on. They worked very hard and did a wonderful job, on pretty short notice. My people were able to complete the rest of the job by the end of the week, because of the response from the Mammoth family. Thanks a million. From the McIntosh family

5 stars!! Mammoth gave me a time frame of between 8 am and 10 am, which was amazing in itself since normally I get time frames of 5 or more hours, but they came in at 9 and got right to work. They fixed my leaking bathtub faucet in less than 30 minutes including getting a stripped screw off. They also waited with me to check that the leak had indeed stopped. Bonus: free estimate!!Wonderful job guys I will definitely use you again!!
Response from the owner:Thank you very for your business it was a pleasure to work for you.

Mammoth Plumbing has been my go-to plumber for the past few years. They have solved minor problems related to clogs, sinks, and the water heater, and they also installed the gas line for a stand-alone home generator. Their pricing is competitive and reasonable, and I trust them to be honest when assessing a problem. Jon and his team conduct their business with integrity and transparency, and I have recommended them to friends and clients over the years. They're fantastic and I cannot recommend them enough.
Response from the owner:Thank you ms. Fultz-smith for the review it's always a pleasure working for such great clients, thanks for the referral.

Fast, fair, courteous, and professional. Highly recommend them. There should be a 6th star. Update. We had some serious under-slab plumbing issues. They were able to accurately diagnose the issue where other companies had failed. They put everything back as it was, and even added some smart clean outs and tie-ins for future plans. The most impressive part was though was how much the hustled to get it all done. They even sent my wife flowers when they learned she had gone into labor. Absolutely amazing.
Response from the owner:thank you Mr. bower, we really appreciate your business!

I just wanted to send you a big shout out for great service. Jimmy came out to look into my washing machine waste line which also has my drain from the AC unit and it had been slightly overflowing. I first used a safe drain opener to possibly open the line, but in addition wanted to have it looked at to make sure everything was okay. He did an outstanding job scoping the line and found just a small amount of sediment on the walls. I just wanted to let you know that I will highly recommend your company to anyone needing quality professional plumbing work done! John
Response from the owner:Thank you so much for your business and your patience, it was a pleasure working for you, I will pass this letter on to jimmy.

I had an under-foundation issue with my plumbing (an absolute nightmare) and this company was awesome. Very professional, obviously knew what they were doing, and the owner had a great way of making me feel like he would solve the problems and calmed me down. It was a major project and they did a great job and the warranty is outstanding. I can't say enough good things about this company. I had 5 other quotes and this one was by far the most professional and expert in this area.
Response from the owner:thank you Mr. ball, it was a pleasure working for you.

Mammoth is the best when it comes to Rinnai tankless water heaters. Ron was on time, professional, and brutally honest about issue. He was able to troubleshoot and found the root cause of why my water heater was acting up. Definitely will use them again and please give Ron some recognition!
