Kegonsa Plumbing was founded in March 2018 by Luke Elsing. After 13 years of plumbing experience, he was exposed to several different owners and management styles. Luke decided to be a different kind of business and prioritize doing what’s best for his customers over his own profit margins. By sourcing only the highest quality products with solid warranties and doing craftsman-quality work on every job, Kegonsa Plumbing earned an A rating on Angie’s List in our very first year of business.

"We used Kegonsa Remodeling for a major kitchen renovation in a nearly 100-year-old house. Before the remodel everything in the kitchen looked cheap and worn down (think 1970s brown, everywhere!), and the overall arrangement of the space was really inefficient. They came in and proposed a design that was the best balance of affordability and ideal features out of half a dozen contractors we interviewed. Once we began working with them, they provided consistent updates and met with us on a regular basis, enough so that even with unavoidable pandemic slowdowns, it still felt like the project was always moving forward. Once the remodel began, they had nearly daily updates for us on what was coming next, and the project actually finished ahead of schedule! Now we have a kitchen that has at least 3x the workspace, a significantly improved flow, and easily twice as much storage as our previous one did. We get compliments all the time, and recommend Kegonsa's work any chance we get!"

We take pride in the quality of work and customer satisfaction that we give each and every customer. We are known to pay exquisite attention to detail while making customer satisfaction our top priority. 7 days a week. Call us today to learn more about how we can help you.

"Kurt was fantastic. Our entire building was suffering with no hot water on a cold winters day. I found Kurt recommended by the maker of our water heaters. I called a bit frantic, recieved a return call within minutes, got great advice, honest folks helped us get things back up and running when most would have let us wait and possibly charged us for something we could do ourselves. We are so glad to find a trustworthy service group, and wouldn't go anywhere else unless they refer us. You simply don't find this type of honest often, I'm proud of them and quite grateful."
