**What does a mold detection dog actually do?**
A question we get a lot:
**“So…what exactly is Ernie looking for?”**
Ernie is trained to help identify the **source area** of hidden mold concerns inside homes and buildings.
That can be especially helpful when:
• there’s a **musty odor** but no visible mold
• a home has had **past leaks or water intrusion**
• moisture may be trapped **behind walls, under flooring, or inside building materials**
• you’re trying to determine **where to focus next**
He’s not replacing building science or proper investigation — he’s helping us **narrow the search** and point us toward where a hidden issue may actually be.
In many homes, that can save a lot of guessing.
Serving **Savannah, Tybee Island, and the surrounding Lowcountry**.
