Diamond Kitchen was very reasonable and they stand behind their work.
I worked with Kenny--he was helpful, friendly, and cheerful--and worked with us to design to our specific needs.
I called Kenny to ask how to adjust the lazy susan cabinet, and he directed me to the service department.
Even though the cabinets were purchased was 4 1/2 years ago, they are coming out to fix my lazy susan cabinet with no charge for the labor. They are doing this even though my now-ex-wife used a low-cost contractor to save a few hundred on the installation (mistake--they did not align the upper cabinets the way they should have).
