“We have used Lyons for plumbing issues a couple of times now and had a good experience each time. Most recently they replaced our hot water heater and from talking with neighbors and coworkers - we paid a very reasonable price. The plumber from Lyon's not only cleaned up nicely from his work, but took the trash from the electrician!”
“We had Lyons Plumbing replace our water heater. There was good communication and then Dan came over and inspected the work to be done. He provided a competitive all-in price, removing the BS you hear with other contractors. On the day, they arrived on time and completed the work without a fuss.”

Recently my hot water heater went out and they ordered a new one and replaced it quickly. The owner Dan and Mark are greatest . This company is 5 STAR plus.”
“I have friends and family members that use this company and they always recommend their services. But man when I tell you that it goes beyond their work ethic. Mark Britt was our hero out the goodness in his heart at the moment he saw us in a place where we needed a hero.
