"The plumber spent a lot of time just trying to figure out the source of the hidden leak. He had a lot of patience. The quality of work was good as was the price. I would definitely hire them again."

"Brian & Eric showed up right on time as they said they would. They quickly identified the problem, quoted me & fixed it. Brian was fair in his quote compared to the run-around I was getting from someone else who sent a junior tech that made me feel a bit overwhelmed and did not resolve the issue. Brian & Eric got right to it and found the problem almost immediately. They pointed out the problem and we discussed the solution in advance. They also made great referrals to other for additional non-plumbing work that needed to be done. Thanks Bran & Eric!"

"I have been using R T Olson Plumbing for all my properties for almost 10 years now. I wouldnâ t think of calling anyone else. They are reasonable, on time, and professional. On more than one occasion they have gone beyond what one would expect for superior customer service. â ï¸ â ï¸ â ï¸ â ï¸ â ï¸ â ï¸"

"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 Turned an outdated bathroom, into a tranquil, and relaxing place to bathe.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!"
