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.

A hot fire alone will not remove significant creosote buildup and can be dangerous, as it risks causing a chimney fire. While the warmth from a fire can help loosen stuck tar, making treatments like creosote logs more effective, it is not a substitute for proper cleaning. For existing creosote, the safest and most effective method is to have your chimney professionally cleaned by a chimney sweep.

While your municipality may have its own regulations requiring pergolas or other structures to be a certain height above a fire pit, the standard recommendation is that the pergola should be at least 10 feet above the fire pit. A taller pergola allows the heat from the flames to dissipate before reaching the structure.

A spark arrestor is a simple metal mesh device that prevents flammable particles from escaping from a combustion source and causing a fire. You typically find these attached to gas or diesel engines on things like cars, generators, and garden tools (lawnmowers, chainsaws, etc.). Fireplace or wood-burning stove chimneys also have spark arrestors attached to or sitting under the chimney cap to capture burning embers.
