Wall-to-wall carpeting can be a blessing and a curse, even to the most careful homeowner. Some homeowners decide to replace their flooring with tile or hardwood and then add an area rug to have the best of both worlds. Proper maintenance can definitely extend the life of any carpet. All carpets that have high traffic areas will need to replaced sooner or later. Some of the signs are obvious, such as, wear spots, stains, color or difference. But some signs are more subtle so you will need to know what they are.
