I have looked for a competent plumber with charges I understand and I found him in Adam with AG Plumbing! He diagnosed my problem within 2 minutes and had me up and running with hot water within 30 minutes. He was very knowledgeable and competent. I highly recommend his work to anyone!

On 12/20/2025 Jim had this to say:
Adam arrived on time. He had the part and had my toilet fixed in about 10 minutes I could not have asked for better service from anyone.

On 11/21/2025 Kevin Willis had this to say:
Great communication! Fixed two sinks and a bath tub very quickly. Also had them come back a few days later to fix something in our shop. Highly recommended.

On 11/8/2025 Christopher Darryn had this to say:
After experiences with a few other plumbing companies, I found A.G. Plumbing to be the most honest, reliable, efficient and with all the experience necessary to complete the work in a very timely manner. That's why they are the only plumbing company whose number I keep on my phone when issues arise.

On 11/5/2025 Mason Lowe had this to say:
A.G. Plumbing is fantastic. The owner Adam is incredibly talented and helpful, and very responsive and timely with his work. My hot water heater went out, and Adam came to check it out the very same day. And by the same time the next day, he had already delivered and installed a brand new one. They are very affordable and competitive with their pricing as well. All around one of the best plumbing service providers in the Treasure Valley!
