The Life Expectancy of Your Home

Every component of your home has a lifespan. Common questions asked by homeowners include when to replace the flooring or how long to expect their siding to last. This information can help when budgeting for improvements or deciding between repairing and replacing when the time comes. We’re all familiar with the cliché: They just don’t build things like they used to. And while this may be true when it comes to brick siding or slate roofing, lifespans of other household components have increased in recent years. Here are the life expectancies of the most common household items (courtesy of NAHB):


Appliances: Among major appliances, gas ranges have a longer life expectancy than things like dishwashers and microwaves.

Kitchen & Bath: When choosing your countertops, factor in the life expectancies of different materials.

Are extended warranties warranted? 

Extended warranties, also known as service contracts or service agreements, are sold for all types of household items from appliances to electronics. They cover service calls and repairs for a specified time beyond the manufacturer’s standard warranty. 

You will have to consider whether the cost is worth it to you. For some, it brings a much-needed peace of mind when making such a large purchase. Also consider if the cost outweighs the value of the item. In some cases it may be less expensive to replace a broken appliance than to pay for insurance or a warranty.
