Do I Need a Liner for My Chimney? A Simple Homeowner’s Guide

A chimney liner might not be the most exciting part of a stove installation, but it’s one of the most important. Its job is simple. It keeps the flue gases safely contained, improves the draw of the chimney, and protects the brickwork from heat and smoke.

Older chimneys can have cracks, gaps, or rough surfaces that affect performance. A liner creates a smooth, sealed path for the smoke to escape, which means a cleaner burn and better efficiency. It also reduces the risk of fumes leaking into your home.

Not every home needs one. Some modern chimneys are already lined. During a survey, we check the condition of your flue, measure its size, and test the draw. If the chimney is damaged, oversized, or giving poor performance, a liner is usually required.

For multi-fuel and log burners, a stainless steel liner is the most common option. It’s durable, safe, and built to handle the high temperatures of solid fuel. A proper liner extends the life of both your stove and your chimney.

If you’re unsure whether your home needs a liner, a quick inspection during your free survey will give you the answer.
