Estimated Life Expectancy of Household Components

Home Inspector with Global Property Inspections

Do you ever wonder how long a certain component in your home might last? The life expectancy of a typical component depends on the use it receives. The National Association of Home Builders' (NAHB) "Study of Life Expectancy of Home Components" created a timeline for you, based on the results of the study, to use before planning your next big home improvement.

Appliances differ in their life expectancies. Gas ranges have the highest life expectancy of 19 years, washers and dryers are expected to last about 14 years, and dishwashers and microwaves are expected to last ten years.

Flooring. All natural wood floorings have a life expectancy of 100 years or more; marble, slate and granite are expected to last for about 100 years; vinyl floors last up to 50 years; carpet last between eight and 10 years.

Kitchen cabinets are expected to last up to 50 years.

Masonry (chimneys, brick veneers, fireplaces) are expected to last up to 100 years.
Countertops have a life expectancy of about 20 years, depending on the type.

Exterior doors (fibreglass, steel, wood) can last as long as the house exists, while vinyl and screen doors have a life expectancy of 20 to 40 years.  

Garage door openers have a life expectancy of 10 to 15 years.

The life expectancy of most components is often overlooked. Most components are replaced before they are worn out because of changes in technology, life styles and consumer preferences. Proper maintenance of these components is important in order to achieve the maximum life expectancy.
