"The gentlemen were very professional, not pushy, they explained what they were going to do and the options we have. Not only did they originally come only to replace a broken tubing from the dishwasher, they rearranged the pipes under the sink, then we hired them to replace the 4 toilets we had. They came on time, and very professionally completed the job. Our in law also had taken a business card from them for a future reference as they are having a home built."

"I explained to the Kay Plumbing guys what I needed done and they gave me a detailed estimate of what they would do and how much it would cost. The prices were fair and they did a great job taking care of a small gas leak and descaling the tankless water heater. Most important of all they were honest enough to say that I did not need to replace some pipes that were rusted which saved me a lot of money. It is a pleasure to work with people who treat you with respect and are so professional."
