We had a new refridgarator installed about 7 years ago when we first moved into our house. We didn't realize until a couple weeks later that the installers didn't tighten up the hose going into the ice maker. Every since we have had an uneven floor in one spot. We want to replace the laminate tile that is in there now with Pergo. What do you suggest we do about the uneven floor? How do you get it even again....sanding...replace...?? There is only about 3-4 square feet that is "bubbled"
