In May 2026 a customer called in the morning about a leaky toilet and left a message; Chris called back right away and fixed it that afternoon. A September 2026 reviewer said Chris fit them in quickly, fixed everything on their list and favored repairing over replacing. In October 2026 a Moultonborough customer wrote that Chris gave advice before arriving and also does house checks in the winter. A September 2026 lake-house customer said the business came right out to look at the job, gave a fair estimate, arrived on time on job day and finished early, moving their laundry from one floor to another with clean piping and drain work; they wrote that his team kept the work areas clean. In a January 2026 review, a customer said Chris lays out different options with approximate costs and never pushes the costliest option. In August 2024 a customer who texted Chris Krotz at 12:45 pm about a new garbage disposal got a reply four minutes later and an opening that same day. In June 2024 a customer with a travel trailer said Chris fixed a leaking shower, a leak under the vanity and the kitchen sink faucet once the needed part came in. A March 2025 customer said the business quickly scheduled and fixed a leak in their hydronic heating system, and an August 2025 reviewer credited Chris with their bathroom remodel.
I had a wonderful experience with Chris. He is very generous with his time and attention. He took the time to give me advice on my problem before even arriving at the house. He was willing to squeeze me in pretty quickly. Not only does he do plumbing, but he also does house checks in the winter. I live in Moultonborough. I highly recommend him.
What can I say - Good people are really hard to find. Took me a long time to find Chris, and I can tell you he is thorough, he is an expert, he is a perfectionist, and his work holds up. Also, the prices were very good.
Came right out to look at the job at our lake house and gave us a fair estimate that was explained well. On job day came right on time, finished early and price was very fair. We moved laundry from one floor to another and all of the piping and drain work was very clean and professionally done. His team kept their work areas clean and they were very respectful of our home and space. Exceeded expectations and highly recommend.
Chris was very responsive and fit me into his schedule quickly. He fixed everything on my list, explained what he was doing, and was great about repairing over replacing. Such a nice guy too - highly recommend!
I called CMK in the morning for a leaky toilet and left a message. Chris called back immediately and came to fix it in the afternoon. His knowledge of the situation was very impressive and his prices very reasonable. I highly recommend CMK plumbing.
