In order to save money, the builders of our house did not put hardwood flooring under our kitchen cabinets. The result is that they sit 3/4″ lower than normal, a big problem for proper fit of our dishwasher and trash compactor. Making matters worse, the floor in the kitchen is not level. Its height changes by 7/8″ over the counter’s 21-foot run. To correct both of these problems, I had to remove all the base cabinets, install a proper height base and reinstall them.
