Combating Moisture: Best Practices for Siding in Humid Climates

When it comes to caring for siding, we can all agree that humidity is a silent but destructive enemy. Whether its moisture damage, mold growth, or rot, some of the most common siding issues can be traced back to high levels of humidity and moisture. 

But moisture damage is not inevitable. That is, not with the right care and maintenance. This blog is your guide to home siding care in a humid climate (or season!). Whether you’re looking to replace siding or prevent future damage, this article has the tips for you! Let’s dive in. 

Understanding Humidity and Its Effects on Siding

Humidity affects different types of siding in different ways. For example: because wood siding absorbs moisture, it is particularly vulnerable to warping and rot. Vinyl siding, on the other hand, may not rot but it will develop mold and mildew which can degrade the surface. And then there are other types like fiber cement siding which are more durable but can still suffer from moisture infiltration if not correctly installed and maintained. 

Humidity Has Nothing on These Best Practices

Now that we’ve laid some groundwork, the question is: “What can you do to make sure your siding lasts?” Here are some tried and true tips.

1. Regular Inspections 

Routine inspections are essential to identify early signs of damage or moisture infiltration. Look for discoloration, warping, and any signs of mold or mildew. Catching these issues early can prevent more significant problems down the line.

2. Proper Installation 

Ensuring that siding is installed correctly is the first line of defense against moisture damage. Use moisture barriers, proper sealing, and ensure that the siding is installed according to manufacturer guidelines. Improper installation can lead to gaps and spaces where moisture will penetrate, causing damage.

3. Cleaning and Maintenance 

Regular cleaning is vital to remove dirt, debris, and mold spores. For wood siding, use a mixture of water and mild detergent. For vinyl and fiber cement, a solution of water and vinegar may be more effective. 

Note: Avoid using high-pressure washers that can force water into the siding. Rely on soaps and detergents with a soft washing method to get dirt and mold off. 

4. Ventilation and Drainage 

Adequate ventilation reduces humidity levels around the siding, helping to prevent mold and mildew growth. Ensure that attics and crawl spaces are well-ventilated and that you have a proper drainage system to divert water away from the siding (this includes gutters and downspouts). 

5. Repairs and Replacements 

Address any damaged or compromised siding as soon as you can. Small cracks and gaps can allow moisture to penetrate, leading to more extensive damage. Also, regularly inspect and repair caulking around windows and doors. If the siding is significantly damaged, consider replacement to prevent further issues.

6. Protective Coatings and Treatments 

Applying protective coatings can create a barrier against moisture. For wood siding, consider water-repellent preservatives and paints. For other types of siding, make sure they are treated with appropriate weather-resistant finishes. These treatments can enhance the durability and lifespan of the siding.

What’s the Takeaway? 

As you can see, maintaining siding in humid climates requires some diligence. But rest assured, with the right care you can add years to your siding, save money in the long run, and enjoy a gorgeous home!
