Step-by-Step Guide

Inspecting the Chimney

Begin by inspecting the chimney to assess the severity of the blockage and identify any potential hazards, such as nests or structural damage.

Preparation and Safety Measures

Put on your protective gear and set up the ladder securely. Lay down a tarp or drop cloth to catch any debris that falls during the removal process.

Using Appropriate Tools Attach the chimney brush to the rods and carefully feed it down the chimney, rotating it to dislodge the breast. Use a flashlight to inspect the progress and ensure thorough cleaning.

Dislodging the Breast

Work the chimney brush up and down several times to loosen the breast. Be patient and persistent, but avoid using excessive force to prevent damage to the chimney lining.

Clean-Up and Post-Removal Precautions

Once the breast is dislodged, use a dustpan and brush to remove any debris from the fireplace. Dispose of the breast properly and inspect the chimney for any remaining blockages or damage.
