Stucco and Exterior Insulation and Finish Systems (EIFS) were popular in the 1990s for their sleek look, but they’ve proven disastrous in moist climates like Portland and Vancouver, WA. These materials trap moisture inside walls, leading to hidden damage like mold, dry rot, and even pest infestations. At Elevate Exteriors, we’ve replaced countless EIFS and stucco homes, uncovering severe structural issues. The best solution? Upgrading to James Hardie fiber cement siding—a durable, moisture-resistant option that protects your home while enhancing its curb appeal.
The Problem with Stucco and EIFS in Moist Climates
Lack of Breathability
EIFS and stucco siding create a solid, monolithic surface that traps moisture inside walls. While these materials may seem like they provide good protection, the problem is that homes in the Northwest—and other humid areas—naturally accumulate moisture over time.
Your home needs to “breathe.” Moisture that gets trapped inside your walls must be able to escape, or else it will cause mold growth, rot, and structural damage. Unlike porous siding materials that allow air circulation, stucco and EIFS fail to provide an effective drying mechanism.
Hidden Damage Beneath the Surface
From our years of experience removing EIFS and stucco, we can confidently say that 100% of these homes have hidden damage. The most common issues we uncover include:
- Moisture Intrusion: Water enters through cracks, unsealed seams, or openings around windows and doors.
- Mold and Mildew Growth: The trapped moisture creates a damp environment inside walls, leading to serious mold problems.
- Structural Rot: When wood framing stays damp, it begins to rot, weakening the structure of your home.
- Pest Infestation: Rotting wood attracts termites, carpenter ants, and other destructive insects.
If you have EIFS or stucco siding, it’s crucial to inspect your home for signs of moisture damage—especially around windows and doors, where staining or discoloration might indicate trapped water.
Why James Hardie Siding is the Best Replacement
Instead of dealing with the endless issues that come with stucco and EIFS, we recommend replacing them with James Hardie fiber cement siding. It offers homeowners long-term durability, moisture protection, and aesthetic appeal.
Superior Moisture Resistance
James Hardie siding is designed to allow for proper moisture management. Unlike EIFS and stucco, it doesn’t trap moisture inside your walls. Instead, it provides a protective barrier while still allowing airflow, reducing the risk of mold and rot.
Increased Home Value and Sellability
Home inspectors are now trained to spot issues with EIFS and stucco. When you try to sell your home, an inspector will likely flag your siding as a red flag, making it harder to sell. Many buyers will either request a discount or require the seller to replace the siding before the sale can go through.
With James Hardie siding, you eliminate these concerns, making your home more attractive to potential buyers.
Aesthetic Flexibility
One concern many homeowners have is losing the Mediterranean-style look they originally wanted. The good news is that James Hardie offers many styles that can match or even enhance the original architectural style of your home. You get the same beautiful appearance but without the problems.
The Long-Term Benefits of Replacing EIFS or Stucco
Choosing James Hardie siding isn’t just about avoiding the problems of EIFS and stucco—it’s about investing in your home’s future. Here’s what you gain:
1. Protection Against Moisture Damage
Replacing stucco with James Hardie prevents water-related issues, reducing the risk of mold, rot, and insect infestations.
2. Lower Maintenance Costs
EIFS and stucco require frequent repairs, sealing, and repainting. James Hardie siding is much easier to maintain, saving you thousands of dollars in upkeep over time.

5. Increased Curb Appeal
Whether you plan to stay in your home long-term or sell in the future, upgraded siding transforms your home’s appearance, making it look brand new.
In Summary
Stucco and EIFS siding were once popular, but they aren’t built for humid or rainy climates. If your home has this outdated siding, you’re likely dealing with hidden moisture problems, mold, rot, and even pests.
Switching to James Hardie siding is the best way to ensure your home stays protected, attractive, and valuable for years to come. At Elevate Exteriors, we specialize in high-quality siding replacements, ensuring that your new exterior is installed with precision and expertise.
