When planning a home renovation, it will help to get a good, thorough inspection of your home. No doubt there are many things you are aware of that need repair or replacement, but there are also many things you can’t see so easily. In addition to the items that need to be repaired now, there could be parts of your house that are nearing the end of their expected life and will need repair soon. The following lists the average expected lifespan of materials and items in a typical home, in years. It may be a good time to replace them at the same time as your renovation. Of course, you will need to know when the item was first installed or how old it is.
