Let’s look more into the details of the importance of installation in relation to the longevity of Hardie siding. 

What factors influence how long James Hardie siding lasts?

Even though Hardie’s fiber cement materials are durable and weather-resistant, if they are not installed correctly, they will not last as long as they should. 

The most important thing to know about the longevity of James Hardie siding is that it must be installed properly with the right installation materials. The fiber cement material of Hardie siding also helps sustain its lifetime. 

1. James Hardie siding is made from fiber cement, which is incredible durable and long lasting

The first reason James Hardie siding lasts so long is because of its fiber cement material. This type of siding will not rot, warp, become misshapen, or crack easily as other siding types can. This is one of the factors that really helps increase the longevity of Hardie siding.

Hardie siding is also made with performance additives that make it ​​non-combustible, resistant to water damage and rot, and withstand any climate. 

Because of this, fiber cement siding is already more durable and longer-lasting than other siding types. But, the quality of the siding installation is just as crucial as the quality of the material.  

2. James Hardie siding must be installed properly for it to last

The installation of any product is crucial to the success of its performance. Hardie siding is no exception to this rule. 

James Hardie outlines their best practices for installing all of their products intended for all Hardie-certified installers. If these best practices are not followed when installing Hardie siding, the results will not be as well as they should be. Your siding will not look and perform as it should, and this, in turn, means it will not last as long as it should.

3. Installers must use the correct installation materials for James Hardie siding to last 

The second part of a proper Hardie siding installation is using the right materials. This includes the right nails, caulk, paint, and tools. 

For example, a quality exterior caulk will have a lifetime of at least 50 years. If a caulk with a 5-year life span is used with a Hardie siding installation, it will not last. This, in turn, affects the longevity and quality of the siding.  

If the wrong type of paint is used on Hardie siding, like watered-down paint, or it is not applied using the right tool, the paint can appear patchy in some areas and affect the appearance and performance of the siding. It will not be as protected as it should with the right paint type.
