🧱 What Is Chimney Flue Lining?

Chimney flue lining refers to the layer inside your chimney that directs smoke and gases safely out of your home. It shields your masonry from heat and flammable byproducts—and keeps your entire system working efficiently.

At Chimney Crickets, we install, repair, and upgrade flue liners for homes throughout Minnesota and Wisconsin. From old clay tiles to modern stainless steel liners, we make sure your chimney performs safely all year long.

⚠️ Signs You Need Chimney Relining

A failing flue liner can go unnoticed—until it becomes dangerous. Watch for:

• 🕳️ Crumbling masonry inside the flue

• 🔥 Smoke leakage or poor drafting

• 🧯 Accelerated creosote buildup

• 💨 Cool or smoky rooms when the fire is lit

• 🧱 Chimney walls showing signs of heat damage

If you’re upgrading your fireplace or switching fuel types, relining may also be required by code.

⚠️ Signs You May Need an Immediate Inspection

If you notice any of the following, don’t wait for your yearly checkup:

• 🔥 Smoke entering your home when using the fireplace

• 🌧️ Water or rust stains inside the firebox

• 🐿️ Sounds of animals in the chimney

• 🌫️ Strong smoky or musty odor from the fireplace

These are signs of potential structural or ventilation problems.
