The damper, located just above the firebox, can open or close the chimney flue. The damper should remain closed unless there’s a fire burning in the fireplace. Closing the damper prevents energy loss through the chimney and cold air from seeping into the home during the winter. Opening the damper helps maintain airflow when there is a fire and prevents smoke and gases from venting into the house.

Some of the most common chimney problems include:

• Creosote buildup

• Chimney blockage

• Deteriorating brickwork or stonework

• Cracked chimney top

• Damaged flashing

• Flue liner damage or deterioration

• Damaged chimney cap

If you suspect you have a chimney problem, contact a masonry contractor for an inspection. 

Neglecting to clean your chimney can lead to serious safety hazards. A primary risk is the buildup of creosote, a highly flammable substance that can ignite and cause a dangerous chimney fire. This buildup can also create blockages in the flue, resulting in poor venting of smoke, soot, and toxic gases like carbon monoxide, which can then enter your home and create dangerously poor indoor air quality. Additionally, creosote is acidic and can damage the chimney's mortar and metal components over time, potentially allowing smoke to leak into your house. To prevent these issues, it is essential to schedule an annual chimney cleaning with a professional.

Wood-burning fireplaces typically make homeowners insurance more expensive, simply because they increase the risk for a fire in your home. Gas and electric inserts are less likely to bring up your insurance rates, but you should always speak with your agent to understand how installing any type of fireplace will affect your premiums.
