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.

Costs range from $500 to $5,000, depending on fire alarms, sprinklers, and safety equipment.

There are a few things you can look out for to ensure your chimney is safe to use. Check for the following issues:

• Cracks or missing pieces in the masonry of the chimney

• Creosote buildup in the chimney, which is a black, tar-like substance

• Cracks, stains, or scorch marks in the firebox

• Water stains in or around the fireplace

• A broken or stuck damper
