Home Systems Life Expectancies

How long can you expect it to last?

You may be planning major improvements to your home or simply be curious about how long you can expect various things to last. It´s useful information, especially if you want to make sure you get your money´s worth.

Many house parts are fully functional for years; others give it up after just a few. A cast iron tub can work as well today as it did when it was first installed in 1888, though it may require refinishing. If maintained, brick and stonework can last centuries.

The following tables show average life expectancies for mechanical systems as well as interior and exterior materials. These have been taken from a wide range of sources including various professional building speciality websites and consumer resources, and are intended only as an estimate. Care and maintenance as well as quality and proper installation also play big roles in performance and longevity.
