Installing a spark arrestor on your home’s chimney is an essential task. It reduces fire risk and ensures your chimney is compliant for insurance and building code purposes. Not having a spark arrestor could invalidate your home insurance or cause snags when it comes to a house sale.

If your oven is new, then it’s likely that the oven smoking is due to it being a new unit. In this case, you don’t need to worry about the oven smoking. However, if your oven is old, you can’t identify any burnt food or grease that could be behind the smoking, or you have concerns about the heating element, then you should hire an oven technician to inspect your unit.

In addition to flashing, a roof cricket can help divert water around your chimney so that it drains properly off your roof. It’s shaped like a double triangle and is installed behind the chimney so that falling water spills evenly down each side. This helps prevent water from accumulating behind your chimney, which can increase water damage and the risk of leaks. 

The International Building Code (IBC) requires cricket installation if a chimney built after 2012 measures over 30 inches in width. Chimneys constructed before that date are typically grandfathered in and aren’t required to have crickets installed.

In some cases, you can use a fireplace once the insert has been removed. However, before burning a fire, you must have a professional inspect it and the chimney to make sure they're functioning properly and no damage has occurred from removing the insert. That’s because using a fireplace without an insert could create fire hazards due to issues with airflow and heat dispersion, depending on the fireplace design and material. A professional can advise on whether you should make certain repairs or modifications before using your fireplace as an open hearth.
