After reading, you will know how to take care of your siding to keep it looking brand new. This will also help you identify any problems before they become too large to handle, so you won’t have to spend money to repair or replace your siding. 


How can I maintain my James Hardie fiber cement siding? 3 ways

As we already alluded to in the introduction of this article, fiber cement siding is one of the most low-maintenance siding types available. 

James Hardie siding products are made with Portland cement, sand, water, and cellulose fibers for strength. 

Their siding is also made with performance additives that make it: 

  • Non-combustible when exposed to fire
  • Resistant to moisture and rot
  • Unable for critters to infest
  • Termite-resistant
  • Able to withstand any climate

So, the material of Hardie siding largely contributes to how little maintenance is required. 

However, you can still do a few things to care for your siding and help make it last. Let’s look more into how you can care for your Hardie siding. 

1. Washing James Hardie siding 

The first way to care for your Hardie siding is to wash it every so often, like once every year or two. Washing the siding will eliminate any dirt and grime that has accumulated. 

The easiest way to do this is with a pressure washing machine. While hosing it down will help to loosen the dirt, the force of the water from a pressure washer will take the dirt off. 

You can also wash the siding with a softer scrubbing tool and some soap for stubborn areas that a pressure washer won't fix. The more often you wash your siding, the easier it will be. 

Think about it - how often do you wash your car? Maybe you have a car wash membership you frequent weekly, or maybe you have a reminder to wash it every month or so. 

Imagine how often we wash our cars and how dirty your fiber cement siding can get as time passes without washing it.

2. Trimming trees and shrubs that may touch the Hardie siding

The second best way you can care for your Hardie siding is to monitor and trim any trees, shrubs, or plants that may be brushing against the siding. 

The reason this is a way to maintain your siding is that if heavy or sharp branches are constantly blowing in the wind, scraping against the siding, it can scratch the paint and the siding board. 

While, yes, you can get your siding repainted in the future if need be, it will cost you. Why not take precautions against potential foreseen costs while you can? 

Heavy branches and trees can also potentially damage the siding boards and cause them to crack, chip, or break off. This will then cause you to have your siding repaired. 

3. Ensuring there are no water leakages around the siding

The third way you can maintain your siding is by ensuring there is no water leaking around or on the siding. This could come from any spigots, hoses, or even a leaky sprinkler constantly hitting the siding. 

While Hardie siding is moisture and rot resistant, hard water can cause discoloration in the paint and boards if constantly leaking onto the siding. Hard water stains come from excess magnesium and calcium in the water. 

This buildup, when left unattended, will get harder and harder to remove the longer it’s there. So, protect your Hardie siding by ensuring there are no leaking water faucets around your home. 


How often should I inspect my James Hardie siding? 

You should inspect your home’s siding routinely once a year. Simply walk around the exterior of your home to make sure there are no damaged areas of your siding. 

You also want to look around the soffit, fascia, trim, and roofline, as these areas are most threatened by rotting and critter infestation. (While, yes, Hardie siding is made to not be appealing to animals and critters, if it isn’t installed properly, they can make their way into your siding.)

Walking around your home routinely will allow you to spot any problem areas and know whether you need to provide some care or not. Maybe you’ll notice some heavy branches scraping the siding or a faucet in your backyard continuously dripping down the siding. 

The more often and regularly you inspect and care for your Hardie siding, the fewer issues, if any, you will run into in the future. If anything has become damaged or needs maintenance, the longer it goes unfixed, the more effort it will take to fix it. 


Is James Hardie fiber cement siding worth it?

It also has a long lifespan and requires relatively low maintenance compared to other types of siding. Additionally, it is available in a variety of styles and colors to suit different home designs.
