How Long Do Things Last? What’s The Life Expectancy Of Home Components?

When building a new home, you are investing a lot of hard work, time, and money.

But have you given any thought to just how long those things that you’re installing are going to last? I have.

 

Recently the National Association of Home Builders (NAHB) shed some light on the life expectancy of common components inside a home — everything from appliances, cabinetry, and flooring… to roofing, plumbing, and HVAC.

Have a look…

Case In Point: My Washer & Dryer

My mother-in-law and I recently had this same conversation.

I asked her how long she thought a washer & dryer should last. She thought maybe 10 years.

I told her my Kenmore washer & dryer were purchased in 1992, making them 15 years old — and still going strong!

Shock and awe were expressed by all.

Turns out, according to this NAHB study, washers and dryers typically last 10 to 13 years.

…So I guess I’ve gotten my money’s worth!

 

Results From The NAHB Study: Summarized

What follows are the life expectancies of home components, based on how long items typically last, on average.

That means that some last longer, and others don’t last as long… based on frequency and type of use, as well as routine maintenance and upkeep.

Some Surprising Findings, In My Opinion

Of all the items listed here, only a few took me by surprise.

Specifically:

• Smoke Detectors only last 5-10 years

 

• Ditto for Home Security Systems

 

• Copper Gutters last 50 years vs Aluminum Gutters 20 years

 

• Copper Downspouts 100 years vs Aluminum Downspouts 30 years

I guess that’s why you’re starting to see so many more copper roofing materials used these days!

 

And I couldn’t help but wonder… what’s the life expectancy of steel metal or aluminum roofs? You see more and more people choosing this form of roofing for their new home, especially log home owners. Did I just miss it in the report?

All in all, I am so thankful to the National Association of Home Builders for doing this study, as the information is worth its weight in gold for homebuilders and remodelers!

The Chances Of A Breakdown…

Now, what are the chances of various household items breaking down? Do you know which products are most likely to need repaired or replaced?

The following numbers are based on 3- to 4-year old items, beginning with those most likely to need repairs:

• Refrigerators (side-by-side with icemaker and water dispenser): 37%

• Washing Machines (front-loading): 29%

• Washing Machines (top-loading): 22%

• Dishwashers: 21%

• Refrigerators (top- or bottom-freezer with icemaker): 20%

• Ranges (gas): 20%

• Wall Ovens (electric): 19%

• Cooktops (gas): 17%

• Microwave Ovens (over-the-range): 17%

• Dryers: 15%

• Refrigerators (top- or bottom-freezer with NO icemaker): 12%

• Ranges (electric): 11%

• Cooktops (electric): 11%
