Understanding Woodpeckers and Your Home
Woodpeckers are fascinating and beneficial birds in nature—but they can sometimes cause unintended damage to buildings, especially when homes have inviting exterior surfaces.
How Does Woodpecker Damage Affect Your Home?
Woodpecker holes may lead to:
- Moisture intrusion and structural deterioration
- Reduced property aesthetics and value
- Repeated and costly repairs
Fortunately, these issues can be avoided with the right solutions.
Why Woodpeckers Choose Certain Homes:
- Surfaces with lower resistance to sharp impact, like cedar siding or Exterior Insulated Finish Systems (EIFS)
- Homes near wooded areas provide ideal nesting and feeding conditions.

Problem: damage caused by woodpeckers and other birds that are naturally attracted to EIFS claddings

Solution: Sto® IMPACT, a fortification layer that can be applied to any StoTherm ci® cladding system

The Sto® IMPACT Advantage
The Sto® IMPACT system withstood 54,900 woodpecker pecks without penetration of the primary lamina which is equivalent of 2 continuous days of pecking vs. the other tested systems that all failed at a much lower number of pecks.
