"We were stuck in the middle of a plumbing project and couldnâ t complete it. We had been trying for hours to drill a hole into a stainless sink to no avail. We needed an expert! I googled plumbers in the area and found Felix right away. It was our lucky day because he was available and he came over immediately. What had taken us hours (without success) took Felix maybe 15 minutes tops. He came with the right tools as well as his personal experience and we were able to continue on with the installation of our reverse osmosis filter installation. Felix was fast, professional, reliable, and very friendly. Thank you Felix! You saved the day!!"

"It went great! I would highly recommend KN Remodeling. We had a master bathroom remodeling done. Turned an outdated bathroom, into a tranquil, and relaxing place to bathe. Nathanel was very professional and handled this project with an open mind to meet our expectations. The project was also managed in a timely manner, it was truly wonderful to see my vision come to life!"

"Alex with 805 Plumbing was quick to respond to our request for help with our septic system. He offered options for us to deal with the problem, and allowed me to watch as he diagnosed our situation with the use of a camera. I never felt pressure to take a path that would be more expensive, and every step of the way I was kept informed of what he had discovered. I am confident that our problems were efficiently taken care of, and although I would not wish septic problems on anyone I would recommend Alex and 805 Plumbing to anyone who is in need of plumbing services. Alex is a reliable, fairly priced, professional, and experienced plumber, and I will use him again in the future."
