When Do You Need to Clean Your Fireplace Chimney?

Chimneys should be cleaned at least once a year, more frequently if you use your fireplace often. To check if your chimney needs cleaning:

Inspect the Flue: Use a flashlight to look inside the chimney. Scrape off a bit of the creosote to see if it’s 1/8-inch thick or thicker. This indicates the need for cleaning. Check for Critters: Since animals like birds, squirrels, and raccoons often nest in chimneys, check for them before cleaning. Remove them if found. Measure Your Chimney: Determine the flue’s size and shape (square or round), and estimate the chimney's height.

Materials Needed for Chimney Cleaning

For a thorough cleaning, you’ll need to gather the following supplies:

Chimney Brush: Choose between wire or plastic, depending on your chimney’s size. Chimney Brush Extension Pipes: Attach to the brush to clean the chimney’s full length. Smaller Stiff Wire Brush: For cleaning the flue’s bottom. Plastic Tarp or Drop Cloth: Protect your living room and furniture from soot. Ladder: To reach the roof if cleaning from the top down. Broom and Dustpan: For cleaning up debris. Dust Mask and Goggles: Protection against soot.

Preparation Steps

Before you begin cleaning, make sure your chimney is clear of debris:

Wear Appropriate Clothing: Old clothes, a bandanna, work gloves, dust mask, and goggles. Prepare Your House: Protect your furniture and rugs with tarps or sheets. Remove the Damper: Clean the damper handle and set it aside to avoid blocking the chimney brush.

Cleaning Methods

Choose the method that best suits your needs:

Clean the Chimney from the Top Down

Set Up the Ladder: Ensure your roof is safe to stand on. Place the ladder next to the house, and climb to the roof with your supplies. Attach the Brush to the Extension Pipes: Clean the chimney from the top down, adding sections of pipe as needed. Disassemble and Clean the Flue: Remove the brush, clean the bottom of the flue, and reattach the damper handle.

Alternative Method: Clean the Chimney from the Bottom Up

Attach the Brush to the Extension Pipes: Insert the brush from the fireplace into the chimney. Use a Pulley System (Optional): For a cooperative approach, use a pulley system with two ropes.

Finishing Touches

Clean up after the job with these final steps:

Shovel Debris: Clear the flues entrance of any collected creosote and soot. Clean the Fireplace: Use the brush and dustpan to sweep up debris from the fireplace and tarp. Dispose of Soot and Creosote: Follow local laws for disposal, as creosote is flammable.
