How long does a concrete house wall last?

You can expect a poured concrete (monolithic) house wall to last for the life of the home, 100 years or more. It is difficult to tell a monolithic concrete house from a concrete block house once it is completed without careful examination at top of walls and/or around electrical boxes. The home shown above in The Villages, Florida, is an example. And here’s a pic of one under construction.

    One factor that can shorten the life of a concrete wall is moisture reaching the reinforcing steel inside. It can cause deep cracks in the wall, and eventually even chunks of the wall to fall out, as corrosion of the steel progresses. To learn more, see What is concrete spalling?. Maintaining a weatherproof surface of the wall and caulking any minor cracks as they arise will stop this potential problem.

NOTE: These life expectancies are based on data provided by InterNACHI, NAHB, FannieMae, and our own professional experience.
