"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."

- Gerald Baker

"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."

Frequently Asked Questions (FAQs)

What size tankless water heater should I get?

Typically we recommend estimating how much water you and your family are using, based on length of showers/baths, how many people are in your household, and how often other appliances are used, (such as the dishwasher and clothes washer). You can then contact your plumber and give them this information for sizing suggestions.

When it's cold outside, will my outdoor tankless water heater still work?

This is not a problem for tankless hot water heaters, even in the coldest temperatures. These outdoor units are made to function below -30°F!
