Life Expectancy on Home Components
Below is a list of home components and the life you should expect from them. It should be noted that this can vary
depending on the quality of these components as well as the quality of workmanship of installation.
Of the major appliances in a home, gas ranges have the longest life expectancy, at 15 years. Dryers and
refrigerators last about 13 years. Appliances with the shortest life spans are: compactors (six years), dishwashers
(nine years) and microwave ovens (nine years). Some appliances don't meet their life expectancy, however, because
changes in styling, technology and consumer preferences may make newer products more desirable. Also, how long
they last depends on how much they are used.
Cabinetry and Storage
Kitchen cabinets are expected to last up to 50 years, medicine cabinets for more than 20 years and garage/laundry
cabinets for 100 years or more. Closet shelves can last for a lifetime.
Concrete and Masonry
Masonry is one of the most durable components of the home. Chimneys, fireplaces and brick veneers can last a
lifetime, and brick walls have an average life expectancy of more than 100 years.
Natural stone, which is less expensive than a few years ago and gaining in popularity, can last a lifetime. Cultured
marble, by contrast, is relatively short-lived, with an age expectancy of 20 years.
The life span of these can vary significantly according to different climates, but they should be around for a good 20
years under ideal conditions.
Exterior fiberglass, steel and wood doors will last as long as the house stands, while vinyl and screen doors have life
expectancies of 20 and 40 years, respectively. Closet doors are expected to last a lifetime, French doors for 30 to 50
Electrical and Lighting
Floor and roof trusses and laminated stranded lumber are good for a lifetime, engineered trim for 30 years.
Faucets and Fixtures
Kitchen sinks made of modified acrylic will last 50 years, faucets will work properly for about 15. Bathroom shower
enclosures can stick around for 50 years, although the shower doors could be in a serious state of decline in about
20 years. Shower heads last a lifetime, as will toilets, although tank components require some maintenance. The
durability of whirlpool tubs ranges fairly widely - from 20 to 50 years - depending on use.
All natural wood flooring, and marble, slate and granite will last for 100 years if they are well taken care of. Vinyl
floors will endure for up to 50 years, linoleum about 25 years and carpet between eight and 10 years, depending on
traffic and care.
Footings and Foundations
Poured as well as concrete block footings and foundations last a lifetime, assuming they were properly built. Termite
proofing will protect foundations for about 12 years if the chemical barriers put in place during construction are left
intact. Waterproofing with bituminous coating can start to spring leaks in 10 years, unless it cracks, in which case
mortal damage is immediate. Concrete or cast iron waste pipes are made to last a century at least.
Framing and Other Structural Systems
Poured-concrete systems, timber frame houses and structural insulated panels will all last a lifetime, as will wall
panels and roof and floor trusses. Softwood, hardboard and plywood average 30 years, while OSB and particleboard
last twice as long.
Garage doors last 10 to 15 years, and light inserts for 20.
A built-in audio system will last 20 years, but security systems and heat and smoke detectors will only be around for
five to 10. Wireless home networks and home automation systems are expected to work properly for more than 50
Heating, Venting and Air Conditioning
HVAC systems need proper and regular maintenance in order to work, but even when they are pampered most of
their components last only 15 to 25 years. Furnaces live for 15 to 20 years, heat pumps for 16 and air conditioning
10 to 15. Thermostats usually are replaced before the end of their 35-year life span because of technological
Tankless water heaters last more than 20 years, while an electric or gas water heater has a life expectancy of about
Insulation and Infiltration Barriers
Cellulose, fiberglass and foam used in insulation materials will last a lifetime provided that they are not punctured, cut
or burned; are kept dry; and are not subjected to UV rays. This pertains whether the insulation was applied as loose
fill, house wrap or batts and rolls.
Job Site Equipment
Ladders last a lifetime, lifts eight to 10 years.
Molding and Millwork
Custom millwork and circular and spiral, pre-built and attic stairs are all expected to last a lifetime.
Paints, Caulks and Adhesives
Interior and exterior paints can last for 15 years or longer, although home owners tend to repaint more often.
Hardboard and softwood panels are expected to last 30 years, while oriented strand board and particleboard have a
life expectancy of 60 years. Wall panels are expected to last for a lifetime.
Slate, copper and clay/concrete roofs have a 50-year life expectancy; asphalt-shingle roofs, 20 years; fiber cement
shingles, 25 years; and wood shakes, 30 years. However, the life of a roof depends on local weather conditions,
proper building and design, material quality and adequate maintenance.
Siding and Accessories
Outside materials typically last a lifetime. Brick, engineered wood, both natural and manufactured stone and fiber
cement will last as long as the house. Exterior wood shutters are expected to last 20 years, depending on the
weather. Gutters made of copper can last 50 years, of aluminum, 20. Copper downspouts last 100 years or more;
aluminum, 30 years.
Site and Landscaping
Most landscaping elements have a life expectancy of 15 to 25 years. Sprinklers and valves last 20 years;
underground PVC piping, 25 years. Polyvinyl fences are designed to last a lifetime, and asphalt driveways should
last up to 15 to 20 years. Tennis courts can last a lifetime if they receive a new coat when they need one every 12 to
15 years. The concrete shell of a pool should do swimmingly for more than 25 years; the interior plaster and tile will
start showing their age in about 10 to 25 years.
Walls, Ceilings and Finishes
They should stick around for the entire life of the home.
Windows and Skylights
Aluminum windows last between 15 and 20 years, while wooden windows can last upwards of 30 years.
