Identifying Rotten Wood: Signs and Causes

Before tackling rotten wood, it’s critical to identify signs early to prevent further damage.

Common Indicators of Wood Rot:

• Crumbling or soft areas in siding.

• Discoloration, often black or gray patches.

• Visible mold or mildew growth.

• Peeling paint, signaling moisture infiltration.

Primary Causes of Wood Rot:

• Excessive moisture exposure.

• Improper sealing or poor initial installation.

• Lack of regular maintenance and repainting.

Quick Inspection Tips:

• Regularly check siding, especially after heavy rains or storms.

• Press gently on suspected areas—soft wood typically indicates rot.

• Pay attention to shady or moisture-prone sides of your home.

Repair vs. Replace: Making the Right Choice

Deciding whether to repair or fully replace your siding is vital for long-term home health.

When to Repair:

• Minor, localized wood damage.

• Surface-level decay that hasn’t deeply compromised structure.

• Budget constraints where full replacement is temporarily impractical.

When Replacement is Essential:

• Widespread or deep structural damage.

• Severe moisture issues or mold infestation.

• Frequent repairs have become costly and ineffective.

Important Considerations:

• Cost-effectiveness: Frequent small repairs may become more expensive than replacement over time.

• Structural integrity: Full replacement often provides superior long-term security.

• Aesthetics: Uniform appearance after replacement enhances curb appeal.
