“What a great experience working with Kegonsa Plumbing! We were looking to install new kitchen countertops and were having a horrible time finding a company that offered reasonable pricing for good quality quartz. Luke and his team not only helped us find great quartz for our kitchen (within our budget), but they were always very quick to respond to any questions we had along the way. The customer service was great, the install was quick, and I’m in LOVE with how my new kitchen turned out. I would recommend Kegonsa Plumbing to all my family and friends looking to make house improvements.”
