Prevent Moisture and Mold Issues with Hardie Siding
When moisture infiltrates siding—rot, mold, and deterioration can result. If left unnoticed or unattended to, it can eventually compromise your home’s structural integrity, causing costly issues.
Mold contributes to respiratory problems, can trigger allergic reactions, and increases the risk of airway infections. The good news is, you can maintain a healthy home that is structurally sound by avoiding moisture-related issues with fiber cement siding.
Popular James Hardie siding delivers the moisture resistance you need to keep your home free from moisture and mold issues. Here’s how:
Strong Makeup
Siding’s biggest enemy is water infiltration, making moisture resistance a high priority for your replacement siding. James Hardie combines cement, sand, and cellulose along with a proprietary blend to create their top-tier siding panels, which homeowners throughout the U.S. love. This robust combination of ingredients creates siding that endures the elements 24/7, including the rain and storms of spring, intense heat of summer, wind and precipitation of fall, and ice and snow of winter.
Reliable Moisture Resistance
Kansas City area homeowners understand the high demands they put on their home exteriors, particularly during severe storms which include strong winds, rain, and more. Protecting your most significant investment from the perils of water intrusion is of utmost importance—and Hardie siding and trim deliver! Expect water to flow down your exterior without seeping into it when you have the reliable fiber cement boards from James Hardie.
Research-Based Protection
James Hardie studied the effects of the weather on the long-term performance of siding. The result? The creation of the Hardie® Zone System, which provides the exact details you need in a siding product to endure your area’s specific climate! Their HZ5 siding product is ideal for Kansas City homeowners because it resists damage from ice, snow, wet and freezing conditions.
These siding and trim products are engineered to prevent damage from moisture in areas with extreme seasonal temperature variations and precipitation throughout the year. Durable Hardie siding and trim doesn’t just perform well in the Kansas City area with the precipitation we experience throughout the year—it was engineered for it!
Outstanding Longevity
Hardie siding and trim lasts up to 50 years when they are installed by a well-trained Hardie contractor (like us!). After all, siding materials are only half of the equation when it comes to longevity. A meticulous installation is a vital part of its endurance. You can expect the moisture resistance Hardie was designed to deliver to be intact throughout its lifespan, giving you peace of mind that your home won’t suffer the damaging impact of water intrusion.
Simple Upkeep
Hardie siding is so well made that it doesn’t require a lot of maintenance or repairs. It benefits from being washed once or twice a year. Just start at the top and go toward the bottom to ensure you don’t spray water up into the joints between siding boards. Be kind to your siding and keep it in good shape by using a garden hose rather than a power washer. If you notice the caulking is starting to wear out, simply remove and replace it with a fresh bead of caulk, and gently press it into siding joints. Pay close attention to the areas between siding panels and around windows and doors. Since Hardie siding is so strong, you won’t have to do much to keep it intact so it delivers the moisture resistance your exterior needs.
Lasting Protection
When siding isn’t resilient, moisture invades and causes rot. Prolonged exposure to water creates expensive damage to your exterior. The very part of your home that should be protecting you begins to become a gateway for water to seep in and wreak havoc on your house.
Hardie siding and trim’s resistance to moisture absorption greatly reduces the risk of rot developing in your home siding. Hardie’s ability to repel water keeps the deterioration and weakening of siding material from occurring. As a result, you can expect the structural integrity of your home to endure. The lasting protection from moisture that Hardie provides is a key to its longevity, making it a smart investment.
Avoid Costly Moisture Damage
Wood Requires Tedious Maintenance
Homes covered in wood siding need regular painting to keep them sealed against water penetration.
Hardie’s solution: The resilient makeup of Hardie siding lasts decades and requires almost no maintenance, while its moisture resistance keeps on working.
Wood Tends to Warp
If moisture seeps into wood siding, it will warp—leading to the entrance of even more moisture, which leads to rot and mold.
Hardie’s solution: The Hardie® Zone system ensures your siding repels water rather than absorbs it, so your panels won’t warp or open the door to moisture issues like mold and rot.

Reviews
We talked to multiple companies while deciding who to use for the exterior of our home. Safe Harbor was transparent, fast, and offered James Hardie siding compared to all the other companies only offering vinyl. Safe Harbor was much more affordable than many of the other companies, who just wanted as much money as possible. We are extremely happy with our siding, soffit, fascia, flashing, gutters, windows and the guarantee that comes with their work. If there was any more work to be performed, without a doubt, we would chose safe Harbor again.
Safe Harbor installed James Hardie siding, soffits, and gutters. The install was meticulous and our home was left cleaner than when the company showed up. The level of detail in the install was beyond expectation! We are so pleased with the quality of the work and the professionalism of the install team!
