HORIZON PLUMBING LTD BBB Business Review

“The tech that came to check our lack of hot water was terrific and represented your company very well. He was very courteous and thorough!!”

“The guys did and excellent job with my tankless system. I bought all of the parts and pieces for the system and they did an awesome job of installing and it works great just like the tank system with a circulation pump. We can’t tell the difference but we have the piece of mind of no tanks above our master bedroom which can cause a lot of damage. Thank you very much for the great installation.”
