What Is Masonite Siding?

Also called hardboard siding, masonite is made from wood fibers that are held together with resin or glue. The result is a low-cost siding material that looks like real wood without the expense and maintenance of real wood siding. 

It initially grew in popularity because it’s a low-cost siding option that is easy to install and customizable through painting or staining. 

Common Problems With Masonite Siding

Unfortunately, many homeowners realized that there are several significant downsides to this material, which is why we feel strongly that you should replace masonite siding with James Hardieplank. Let’s explore some of the most common issues you can expect when you have masonite siding: 

• Blistering: After exposure to heat and moisture, the paint on masonite siding may start to blister and bubble off. This is not only an eyesore, but it can also lead to moisture problems underneath the paint. 
• Discoloration: The resin in masonite siding makes the material prone to staining. In fact, these stains can even seep into new coats of paint, leading to unsightly discoloration. 
• Insect damage: Pests like termites and carpenter ants can bore into masonite siding, which compromises the structural integrity of your exterior. 
• Mold and mildew growth: When masonite siding gets wet, the moisture tends to stay in the boards, which leads to mold and mildew growth. 
• Rotting: Because masonite siding retains moisture, it’s also common for the material to swell, rot, and buckle over time. When the siding absorbs too much moisture, it will start to soften and decay. Unfortunately, this can’t be repaired, so the siding must be replaced instead. 

A Better Alternative to Masonite: James Hardie Siding

When you need new siding, a better option to consider is James Hardie fiber cement siding. Much like masonite, you can choose a James Hardie siding option that mimics the look of wood, but you won’t have to worry about durability concerns. 

Here are a few of the reasons we prefer James Hardie siding to masonite. 

It’s Fire-Resistant

Since James Hardie siding isn’t a combustible material, it won’t contribute fuel in the event of a fire. This can help give you extra peace of mind about your family’s safety. 

It’s a High-Value Investment

When you install new siding, it’s important to make sure you’re choosing a material that adds to your home value rather than detracts from it. Here in North Carolina, you can expect to recoup around 96.1% of your cost when you install a fiber cement siding material like James Hardie, making it one of the highest-value projects you can do. 

It’s a Low-Maintenance Option

With some siding materials, you’ll have to repaint or re-stain it every few years to keep it looking great. James Hardie siding, however, requires very little maintenance. As a good rule of thumb, you should clean it with a soft-bristle brush and your garden hose twice a year. Otherwise, there’s nothing else you need to do!

It’s Resistant to Damage From Pests

While termites, woodpeckers, and carpenter ants can take a toll on masonite siding, you won’t have to worry about pest damage if you have James Hardie siding. The material is designed to resist pest damage so your home is less vulnerable to infestations. 

It Withstands Even the Harshest Weather Extremes
