Corspect Advanced Home Inspection

When preparing to purchase a home or owning a home it is a good idea to understand the life expectancy of the appliances and structural parts that make up your home. Below is a summary of these items based upon a review of the National Association of Home Builders “Study of Life Expectancy of Home Components” which gives a good guesstimate of life-cycle data based on data from product manufacturer and testing labs.

The life expectancy of appliances depends on several factors, the most important is the extent of use it receives. Typically speaking, many appliances are often replaced before they are worn out because of a desire to update the style, technology and preference of the appliance itself. Typically speaking appliance life expectancy is:
• Gas Ranges – 15 years
• Dryers and Refrigerators – 13 years
• Trash compactors – 6 years
• Dishwashers – 9 years
• Microwave ovens – 9 years

Cabinetry and Storage
• Kitchen cabinets – 50 years
• Medicine cabinets – 20+ years
• Garage/laundry cabinets -100+ years
• Closet shelves are expected to last for a lifetime.
