Cabinets should be replaced after a few indices of age and wear. If your cabinetry is constructed from particle board or an MDF material, you will likely see the deterioration of that material, either in the side walls or the floor of the cabinet. Another indicator would be a thermofoil-wrapped door material. It is common to see peeling of this finish around stove and microwave as the combination of heat and moisture contribute to the deterioration of the adhesives binding the finish to the substrate. On cabinetry built prior to around 1970, many cabinet doors were constructed in a partial inset styling. As the cabinets age and the home settles, you will notice rubbing between the door and frame of the cabinet, sometimes causing the door to stick shut or to not close properly. Another reason to consider replacing cabinets is that you want to take advantage of new storage features that were not available when the space was last remodeled. Some examples of this include waste and spice pull-outs, specialty cookware and lid organizers, and a designated home for the dreaded Tupperware stack. Finally, you may find your existing kitchen layout is not addressing your current needs as a homeowner. Changing from a galley-style kitchen to an open concept would be an example of this change, which will require new cabinets.
