How to Make a Spark Arrestor

Stove spark arrestors are devices that fit over the chimney of a woodstove or fireplace, and keep embers or sparks from entering the air; causing fires elsewhere. The embers are caught by the wire mesh of the spark arrestor and either burn off or fall back into the fire. Building a simple and inexpensive spark arrestor can save you alot of headache in the long run.

Use the tape measure to measure the perimeter around the end of the stove pipe.

Cut a length of wire mesh that equals the perimeter and is 8 inches tall.

Roll the mesh into a cone shape and use the wire to "stitch" the edges together.

Slide the cone onto the end of the stove pipe prior to starting a fire in the stove.


  • Always use spark arrestors during the Fall and Summer months to avoid starting forest fires.
