We were given a window of 1-5 p.m. For our installation, but it did not arrive until 6:30 p.m. This really messed up our evening dinner plans (it was our anniversary). Outside of the late arrival, the installation went great! Lyle and Jon were quick and thoughtful about getting in and getting the installation done efficiently without making a mess. They took the time to show us how to use the new dishwasher and answer any questions we had. We highly recommend them.
