In 2025, I hired Jim Kitchen of Mamason Koi to transform my pond into a fishing pond. I want to begin by saying that I believe Jim is a genuinely good person, and this review is intended to honestly reflect my experience.
When I first spoke with Jim, I explained that my vision was to create a pond that could eventually be stocked for fishing. Another company I had consulted didn't understand what I was trying to accomplish, but Jim assured me he did and was excited to help bring that vision to life.
During the project, I purchased approximately $2,500 worth of koi from Jim and hired him to build a $45,000 waterfall, install electrical service, and add an aeration system to support a healthy fish population.
The finished waterfall is beautiful, and I'm very happy with both the waterfall and the quality of the koi.
Unfortunately, the overall project experience was disappointing.
The original timeline was approximately six weeks, but the project ultimately stretched to nearly four months. While delays can happen, communication throughout the process became increasingly difficult.
We also experienced ongoing water loss because the pond did not have a liner and water was leaking from somewhere in the pond. Jim recommended applying bentonite clay to help seal the pond naturally.
Another major issue occurred when approximately 4,000 pounds of bentonite clay were delivered to my property. After dropping off the material, Jim became unreachable for several days despite approaching rain and no work being completed. When I finally reached him, he explained that he was dealing with personal issues and offered to refund the remaining balance rather than finish the project. Because the clay had already been delivered, I spent over an hour on the phone convincing him to complete the work.
While the work was eventually finished, the bentonite clay has left the pond so cloudy that visibility is less than half an inch. Jim insured us the clay would eventually settle so that we could see through our water again. Fast forward 8+ months and we still can't see anything in the pond, despite doing several 50% water changes. We can no longer enjoy seeing our koi or much of anything beneath the surface, which was a significant disappointment after investing in both the fish and the pond.
The last major issue involved the continuation of the project. After discussing everything with Jim, I was willing to move forward and hire him for additional work, including pond pump covers and stocking the pond with game fish, the original purpose of the entire project. Jim seemed enthusiastic about continuing. However, despite multiple text messages over approximately six weeks, I never received the requested quote or any meaningful follow-up. Eventually, I expressed my frustration, explaining that I had repeatedly asked to move forward without success.
In the end, we mutually agreed that it was best not to continue working together.
Based on my experience, I believe Jim has strengths in koi selection, pond maintenance, and building attractive water features. However, I also experienced significant project delays, inconsistent communication, and personal circumstances that repeatedly affected the completion of the work.
Given the overall investment of roughly $60,000, I expected a much higher level of project management and follow through. Throughout the process, I believe I was patient and flexible, giving Jim considerable freedom to complete the work as he saw fit.
My hope in writing this review is not to discourage anyone from hiring Jim, but to provide an honest account of my experience so prospective customers can make an informed decision and have realistic expectations regarding timelines, communication, and project completion. read more
