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!"

Full service handyman located in the Madison area. Willing to do the repairs your home needs. Free estimates and Professional Services. We treat your home as if it were our own !

"We have been using Madtown Homeworks LLC numerous times the past few months, and we nearly always had Jerry helping us. We were so impressed by the breadth of projects he could complete and his focus on good craftsmanship in his work. We also had Mike assigned to help us out once when Jerry was not available, and he was excellent as well. Most of our home improvement projects are now finished, but if another set of projects arise, we would call them again in heartbeat."
