Mark Zimmerman was a joy to work with. I bought a new handicapped height toilet and needed a plumber willing to pick it up from Home Depot, bring it here, remove the existing toilet and install the new toilet. Note: I called Habitat for Humanity ReStore to see if they could take the toilet just removed as a donation. They could so Mark moved it to the garage for me. If I hadn't arranged that he was willing to take it with him and dispose of it. I put in a request on HomeAdvisor at 1AM and got a call from Mark at 7AM this morning! He then offered to do the job after his 9AM appointment today! From contacting HomeAdvisor to Mark's completion of the installation was done in 13 hours! That said, Mark didn't rush at all. He's efficient, confident and a perfectionist and it shows in the quality of his work. He is also just a genuinely good guy, a pleasure to be around and really cares about making the customer happy. Before he left, Mark made sure that I inspected his work, got any questions answered and asked if there was anything else I needed. Those are exactly the things I look for. I've built a couple of homes and remodeled others so I've had plenty of experience with plumbers. Mark is top notch. His prices are fair and he didn't add any extra charges. Mark is my new go to guy and I'd highly recommend him to anyone.
