Fireplace Damper Repair & Replacement

The fireplace damper is the movable metal plate that regulates airflow between your firebox and flue. A properly functioning damper allows you to open the flue when burning and seal it tightly when the fireplace is not in use, preventing conditioned air from escaping up the chimney and blocking cold downdrafts, rain, and insects from entering the home. When a damper is stuck, rusted, warped from heat, or missing entirely, both energy efficiency and indoor air quality suffer significantly. Chimney Care Chimney Sweeps diagnoses damper problems and provides repair or full replacement using quality cast iron and stainless steel components.

Traditional throat dampers — located just above the firebox — are accessible for repair or replacement without roof work. We clean, lubricate, and adjust throat dampers that are stiff or partially stuck, and replace those that are cracked, broken, or corroded beyond service. We also install and replace top-mount dampers, which sit at the top of the flue and combine the functions of a damper and a chimney cap into a single weather-tight unit operated by a stainless steel cable from inside the firebox. Top-mount dampers provide a superior airtight seal compared to most throat dampers and include an integrated rain and animal barrier.

A leaky or inoperable damper can add hundreds of dollars annually to heating and cooling costs.
