Home component life expectancy chart

Appliances

Appliance life expectancy depends to a great extent on the use it receives. Consumers often replace appliances long before they become worn out due to changes in styling, technology, and consumer preferences.

HVAC (heating & cooling)

Thermostats may last 35 years but they are usually replaced before they fail due to technological improvements.

Roofing

The life of a roof depends on local weather conditions, building and design, material quality, and adequate maintenance. Roofs in areas that experience severe weather, such as hail and tornadoes, may experience a shorter-than-normal lifespan overall or may incur isolated damage that requires repair in order to ensure the service life of the surrounding roofing materials.

Plumbing, fixtures & faucets

The quality of plumbing fixtures varies dramatically. The mineral content of water can shorten the life expectancy of water heaters and clog showerheads. Some finishes may require special maintenance with approved cleaning agents per the manufacturers in order to last their expected service lives.

Electrical

Copper-plated wiring, copper-clad aluminum, and bare copper wiring are expected to last a lifetime, whereas electrical accessories and lighting controls, such as dimmer switches, may need to be replaced after 10 years. GFCIs could last 30 years, but much less if tripped regularly. Remember that faulty, damaged or overloaded electrical circuits or equipment are the leading cause of house fires, so they should be inspected regularly and repaired or updated as needed.

Windows

Aluminum windows are expected to last between 15 and 20 years, while wooden windows should last nearly 30 years.

Doors

Exterior fiberglass, steel and wood doors will last as long as the house, while vinyl and screen doors have a shorter life expectancy. The gaskets/weatherstripping of exterior doors may have to be replaced every 5 to 8 years.

Flooring

Flooring life is dependent on maintenance and the amount of foot traffic the floor endures.

Foundations

Concrete and poured-block footings and foundations will last a lifetime, assuming they were properly built. Waterproofing with bituminous coating lasts 10 years, but if it cracks, it is immediately damaged.

Sidings, flashings, gutters & accessories

Outside siding materials typically last a lifetime. Some exterior components may require protection through appropriate paints or sealants, as well as regular maintenance. While well-maintained and undamaged flashing can last a long time, it is their connections that tend to fail, so seasonal inspection and maintenance are strongly recommended.

Adhesives, caulk & paint

Surface preparation and paint quality are the most important determinants of a paint's life expectancy. Ultraviolet (UV) rays via sunshine can shorten life expectancy. Additionally, conditions of high humidity indoors or outdoors can affect the lifespan of these components, which is why they should be inspected and maintained seasonally.

Cabinetry & storage

Ceilings & walls

Walls and ceilings last the full lifespan of the home.

Countertops

Natural stone countertops are becoming more popular, and one can expect them to last a lifetime. Cultured marble countertops have a shorter life expectancy, however.

Decks

Decks are exposed to a wide range of conditions in different climates, from wind and hail in some areas, to relatively consistent, dry weather in others.

Engineered lumber

Floor and roof trusses and laminated strand lumber are durable household components, and engineered trim may last 30 years.

Fasteners, connectors & steel

Fastener manufacturers do not give lifespans for their products because they vary too much based on where the fasteners are installed in a home, the materials in which they're installed, and the local climate and environment. However, inspectors can use these guidelines to make educated judgments about the materials they inspect.

Framing

Framing and structural systems have extended longevities; poured-concrete systems, timber frame houses and structural insulated panels will all last a lifetime.

Garages

The quality and frequency of use will affect the longevity of garage doors and openers.

Home technology

Home technology systems have diverse life expectancies and may have to be upgraded due to evolution in technology. Batteries in carbon monoxide and smoke/heat detectors should be changed at least annually.

Insulation & infiltration barriers

As long as they are not punctured, cut or burned and are kept dry and away from UV rays, cellulose, fiberglass and foam insulation materials will last a lifetime. This is true regardless of whether they were installed as loose-fill, housewrap or batts/rolls.

Masonry & concrete

Masonry is one of the most enduring household components. Fireplaces, chimneys and brick veneers can last the lifetime of the home.

Molding, millwork & trim

Custom millwork and stair parts will last a lifetime and are typically only upgraded for aesthetic reasons.

Panels

The lifetime of any wood product depends heavily on moisture intrusion.

Radon systems

Radon systems have but one moving part: the radon fan.

Site & landscaping

Site and landscaping elements have life expectancies that vary dramatically.

Swimming pools

Swimming pools are composed of many systems and components, all with varying life expectancies.
