Customer Reviews

Jim Lee

Hard Knox Plumbing did a great job helping me with a plumbing issue at one of my rental properties in Knoxville. They were responsive, professional, and clear with their pricing and scope of work. They diagnosed the issue, installed a pressure regulating valve, replaced the failed shower cartridge, checked for leaks, and provided a clear invoice with warranty information. I appreciated their communication, fair pricing, and willingness to work with me to keep the repair scope practical and reasonable. I would recommend Hard Knox Plumbing to other property owners and homeowners looking for dependable plumbing service in the Knoxville area.

Hard Knox was great. We had a water softening and filtration system put in. They were on time, very professional and friendly and did a great job. Would not hesitate to highly recommend them.

Scott Snyder

I can't begin to thank Hard Knox Plumbing. They were great in helping when my water heater decided that it was time to cross over to water heater nirvana. Very professional, prompt, courteous and did a great job. I would highly recommend to anyone! This is a great local company for Knoxville.

Highly professional and frendly crew. Did a great job. Cannot give them a higher recommendation. Replaced all of the old galvanized pipe and drain pipes in the house. These guys do a great job and stand behind their work. Super easy to work with.

My neighbor recommended Hard Knox Plumping to me so I called and spoke with Danny Ferris to set an appointment. Danny was on time, very professional and took the time to inform me on what the best options were to replace an aging 70 gallon water heater. Danny and his assistant, Anthony, did a great job installing a tankless water heater and house carbon filter system. During the installation, they both showed a high level of attention to detail and pride in workmanship. They did a superb job. 5 stars.
