In this video, we reveal the truth about fiber cement upkeep, why it outperforms wood and vinyl, and how Southwest Exteriors ensures long-term peace of mind for Texas homeowners.

Where the “High Maintenance” Myth Comes From

1. People Confuse It with Wood Siding

Hardie siding looks like beautiful, classic wood—but it doesn’t act like it.

✅ It doesn’t rot
✅ It doesn’t warp
✅ It doesn’t attract termites

What you get is all the charm of wood, without the constant upkeep.

2. People Think It Needs Constant Painting

This is one of the most common misconceptions—and it’s understandable. Hardie looks like painted wood, so people assume it needs frequent repainting.

Here’s the truth:

James Hardie holds paint 3x longer than wood. That means fewer repaints over time—and less maintenance, period.

You might’ve heard about James Hardie’s ColorPlus® Technology—a factory-applied paint finish that’s baked on for durability. In many regions, it performs well.

But here in South Texas? That intense sun can take its toll. We’ve found ColorPlus doesn’t hold up quite as long in our climate.

That’s why at Southwest Exteriors, we install primed siding and finish it on-site using Sherwin-Williams premium exterior paint. It gives you:

✅ Better color retention in the Texas heat
✅ More flexibility with custom color options
✅ Easier touch-ups down the road

So yes, it will eventually need repainting—but typically not for 10–15 years. And when it does, it’s simple.

3. Some Early Fiber Cement Siding Gave the Industry a Bad Name

Let’s be honest—some older, off-brand fiber cement products didn’t age well. But James Hardie changed that with:

• Climate-specific engineering (HZ5® and HZ10®)

• Rigorous durability testing

• An industry-leading reputation for longevity

Today, Hardie is the gold standard for fiber cement siding—and it shows.

So… What Maintenance Does James Hardie Actually Require?

Here’s your full upkeep checklist:

🧽 Rinse once a year with a garden hose and mild soap
🔍 Check caulking around windows and joints annually
🎨 Repaint every 10–15 years, depending on sun exposure

That’s it. No sealing, no staining, no scraping. And no headaches.
 

Why It’s Perfect for Texas Heat

The Texas sun is no joke—but Hardie can handle it.

South Texas falls into the HZ10® climate zone, meaning the siding is engineered for:

🌞 UV protection to keep colors from fading
🌡 Minimal expansion in heat = fewer gaps and failures
🌧 Moisture resistance for humid summers and storms

If you’ve owned wood or vinyl before, the difference is night and day.

FAQs About James Hardie Siding Maintenance

Q: How often will I need to repaint it?
Most homeowners go 10–15 years before repainting. We use Sherwin-Williams paint for a longer-lasting, Texas-proof finish.

Q: Does it need to be sealed or stained?
Nope. It comes pre-sealed and ready for long-term use.

Q: Can it rot or mold?
No. Fiber cement is non-porous, so moisture doesn’t get in.

Q: Is fiber cement more maintenance than vinyl?
Actually, it’s less. Vinyl warps and fades over time. Hardie holds strong for decades.
