At the same time, it allows the smoke and gases to escape, preventing them from lingering inside your home.

3. Preventing Backdraft:

It’s when smoke or gases enter your living space instead of going up and out of the chimney.

That can be a real downer, right?

That’s why it’s important to have your chimney inspected and cleaned by a professional chimney sweep on a regular basis.
