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

Would highly recommend Mammoth Plumbing! John quickly identified where our leak was and then was very hard-working and persistent in resolving our issue. Also, great customer service when scheduling our appointment.

We had an emergency repair and John Jr showed up within a few hours to take care of it. The work was completed quickly and was a quality repair.

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!!

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.

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.

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
