The difference between was night and day. Koen plumbing returned calls, showed up on time, did quality work and then followed up. I would highly recommend"

"Great service"

"Plumber charged a lot to hack up my house to fix a leaking pipe behind the dishwasher. He didn't hook up the dishwasher drain line correctly and it leaked. Had to fix myself. They used a scrap pipe instead of the proper $2 part. They wanted to charge me a service fee to come out and fix their problem. I would give zero stars if I could. Over $2200 for bad work. Avoid these guys!"

"The guys arrived on time & worked solidly till the work was done. They layed down floor covers case it was wet & nasty outside..I appreciate that. Rafael was the lead installer & he seemed to really know his business. The helper was very quiet & informative when asked a question. All my questions were answered & work done in a timely manner. I had hot water in 1 hr after they had left. Rafael explained everything about the new water heater to me & was very patient. I have no complaints whatsoever with the installation. I do believe the cost of the heater was very high, but that inflation I guess. That’s my only complaint. Nothing to do with the installers. I do look forward to hopefully 15 yrs at least from this heater. "

"I used their coupon for a better price. The plumber fixed the clog quickly. He gave me his assessment upfront and updated me as he troubleshooted. He was patient to answer any questions that I had along the way. If I ever need another plumber for an issue, this company will be my top choice."

"They did a great job. "
