If you remove the flue intending to repair or replace it, you should only use the fireplace, wood stove, or furnace once the flue is in working order. If you cannot replace the flue you have removed, call a chimney repair professional immediately.

Chimney caps are necessary both from a building safety standpoint in most municipalities and to keep your home protected from a variety of issues. Chimney caps are not only mandated by building code in most areas, but they also serve to keep squirrels, raccoons, and other pests out of your home, as well as snow and rain. Therefore, they help to avoid property damage, making them a worthwhile investment.

Grounding is a great first step to prevent electrical shock, but you can take it further with GFCI outlets and AFCIs (arc fault circuit interrupters). In particular, AFCIs help protect against the type of electrical arcs that cause fires, like if a mouse chews on a wire or your laptop starts overheating at the wall. These are required in some areas of your home.

Once your ashes have fully cooled, you can place them in a heavy-duty trash bag and put them into the bin with your normal trash. If you have wood ash, you can add the ash to your composting pile or sprinkle it over your grass or plants directly for added nutrients.
