Install a Spark Arrestor for Chimneys and Stovepipes


Make Resilient Upgrades | Strengthen Your Home • Wildfires

Why does it matter?

Windblown embers from a wildfire can travel up to two miles. They can enter through your fireplace chimney flue, land on ignitable surfaces, and start a structure fire inside your home. If you have a fireplace, you could cause a wildfire in your neighborhood if embers fly from your chimney and collect on vegetation or ignitable surfaces like wood decks or roofs. The good news is that you can help prevent embers from entering or escaping your chimney by installing a simple, affordable fix.

What do I need to know?

Installing a welded wire, or woven wire mesh spark arrestor with openings less than 1/4 inch wide will prevent embers from entering or leaving your chimney.

Where do I start?

Verify that you have working spark arrestors in all chimneys and stovepipes in your home. Have a professional inspection and cleaning at least once per year and twice per year if you reside in a high wildfire risk area.
