Get matched with top fire pit installation pros in New Buffalo, MI

You should never block both the top and bottom of your chimney. Proper airflow is essential because the temperature inside the chimney will still fluctuate as your house warms and cools. Moisture can build up without ventilation, leading to dampness in your walls over time. Blocking the top prevents debris and animals from entering, but the chimney still needs air circulation to avoid condensation issues. Allowing the chimney to breathe maintains the health of your home and prevents long-term damage.

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.

Home insurance prices depend on where you live and the individual insurance company's policies. Some insurers charge a flat fee for fireplaces or wood-burning stoves, which is often a few hundred dollars per year. Other insurers base this fee on a percentage of your annual premium. You may want to check your current or prospective policy before beginning this project.

Although no heating appliance can be entirely risk-free, a fireplace insert is considered a safer alternative to a traditional open fireplace, thanks to their enclosed design. With a sealed combustion chamber, a fireplace insert effectively reduces the risk of sparks and embers escaping into the room, minimizing the chance of an accidental fire.

Additionally, an insert comes equipped with various safety features, such as tempered glass doors that create a barrier between the flames and the surrounding space. This enhances both safety and energy efficiency by preventing heat loss. As an added bonus, many inserts are designed to meet strict safety standards that ensure proper ventilation and combustion.
