Dry Rot: What It Is and How It Affects Your Health
Dry rot is a silent destroyer that can eat away at your home’s structure before you even know it’s there.

If ignored, dry rot can cause thousands in repairs and even compromise your home’s safety.
In this article, we’ll break down exactly what dry rot is, the hidden ways it starts, and how it can affect not just your home, but your health. You’ll also learn the early warning signs to watch for and why trying to handle it on your own could make things worse.
