At Southwest Exteriors, we offer high-quality fiber cement siding from James Hardie. We believe this to be the best siding offered and have become expert James Hardie siding installers for over 30 years. 

James Hardie is the leading manufacturer of fiber cementious products and has gained the title of the best siding replacement solution in North America. 

This article will detail the benefits of James Hardie siding, like its material, maintenance, and installation engineering. After reading, you will understand why Hardie has become the leading siding manufacturer and installer.

It is important to acknowledge that Hardie siding may not be the best solution for every homeowner. 

It is on the higher end of the cost spectrum to replace your siding. However, many contractors offer different payment options to make it affordable. 

If you are a long-term homeowner looking to invest in new, long-lasting siding, Hardie is the best option for you. If you are looking to freshen up your home’s siding before putting it on the market, a less expensive siding type may be better for you. 

If you are contemplating Hardie for your siding replacement, this article will better help you understand the benefits of investing in high-quality siding. 


1. James Hardie siding is fiber cementious 

The material that Hardie siding is made of is the greatest benefit. It is made of Portland cement, sand, water, and cellulose fibers. 

It is also made with performance additives that make it non-combustible, resistant to water damage and rot, and able to withstand any type of climate. 

For San Antonio homes, having a siding that can stand against the brutal summers and frequent cold snaps is essential. 

Most other siding materials come with a number of issues. 

Vinyl expands and contracts in the heat and cold, causing it to crack, bend, and bow. Wood and masonite siding is susceptible to rot. Stucco can also crack and chip over time. 

Hardie fiber cement siding does not have any of these problems. It does not dry out or deteriorate in the sun, and it is incredibly durable. 

This is why Hardie siding is a long-term solution for a siding replacement, meant to last for 40-50 years. 


2. Hardie siding is practically maintenance-free

Because of the durability of fiber cement siding, it requires very little maintenance. You will not have to worry about repairing rot or replacing boards that have cracked. 

Hardie has designed their siding to be impervious to woodpeckers, termites, and other pests. The fiber cement does not create an ideal home, causing them to turn away. 

The best maintenance task you can take to your Hardie siding is to power wash it once a year or every couple of years. This will get rid of any dirt and grime buildup on the siding, which will keep it looking fresh and help maintain the paint.

Paint on Hardie siding lasts longer than other types of siding. However, when excess dirt is left on the siding for years, it will start to infuse into the paint layer. This makes it more difficult to repaint later, which can cost you more money in the long run. 


3. Hardie’s installation processes secure its lifespan

James Hardie has created numerous best practices guides for certified Hardie installers to follow for siding replacements. 

These best practices set a high standard for contractors that install Hardie products to ensure you receive the highest-quality siding replacement. Some contractors will have a certified Hardie inspector look at your siding replacement to ensure it was done under the best practices.

The installation of any siding is one of the most important aspects of a siding project. Even though Hardie is the best fiber cement siding manufacturer, it will not last as long or protect your home as it should.

This is why it is important to choose the right contractor that will install your siding under Hardie’s best practices in order to get the most out of your project.
