Home Component Life Expectancy Chart

Typical Life Expectancy for Components of Your Home

Typical life expectancies for most components found in homes are listed below. These life expectancies have been determined through research and testing based on regular recommended maintenance and normal wear and tear conditions, not extreme weather (or other) conditions, neglect, over-use, or abuse. Therefore, they should be used as guidelines only and not relied upon as guarantees or warranties.

Adhesives, Caulks, and Paints

Surface preparation and paint quality are the most critical 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 these components’ lifespan, which is why they should be inspected and maintained seasonally.

Component Years
Caulking (interior & exterior) 5 to 10
Construction Glue 20+
Paint (exterior) 7 to 10
Paint (interior) 10 to 15
Roofing Adhesives/Cements 15+
Sealants 8
Stains 3 to 8

Appliances

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