Why You Might Need a Chimney Liner
A properly functioning chimney liner (also called a flue liner) is essential for the safe and efficient operation of your stove. Over time, old or unlined chimneys can develop cracks, leaks, or blockages that allow dangerous gases to escape into your home or reduce the efficiency of your stove. If your liner is damaged or missing, it’s time to take action.
Common Signs You Need a New Chimney Liner:
✓ Your stove isn’t drawing properly – Smoke spilling into the room or difficulty getting a fire started.
✓ Aged or unlined chimney – Older homes often have chimneys with no liner at all, increasing fire and carbon monoxide risks.
✓ Cracked or damaged flue liner – Deterioration over time can cause leaks, reducing efficiency and safety.
✓ Excessive soot or condensation – Tar build-up and moisture can indicate poor venting.
✓ Upgrading your stove – Many modern wood burners and multi-fuel stoves require a correctly sized liner for maximum efficiency and compliance with regulations.
Whether your chimney needs a brand-new stainless steel liner, a replacement for a failing flue, or a twin wall system for a home without a chimney, I’ll help you find the best solution for your setup.

FAQs
-
If you have an older chimney, it may not have a liner, which can cause smoke leaks, poor draw, and fire hazards. A chimney liner improves efficiency, prevents dangerous gases from escaping, and ensures your stove meets building regulations. If you’re unsure, I can inspect your chimney and advise on the best solution.
-
Common signs that your flue liner needs replacing include:
Smoke spilling into the room instead of venting properly.
Cracked or damaged liner, which can allow carbon monoxide leaks.
Tar and creosote buildup, causing blockages and chimney fires.
Condensation or damp patches on your chimney.
Difficulty getting a fire started due to poor airflow.
If you notice any of these, it’s time to get your liner checked.
-
Most chimney liner installations take one day, depending on the setup. If your chimney needs additional repairs or a twin wall system (for homes without a chimney), it might take a little longer. I’ll give you a clear timeline before starting.
-
Chimney liner installation must meet strict building regulations and safety standards. A poorly fitted liner can lead to smoke leaks, carbon monoxide risks, and poor stove performance. As a HETAS-certified installer, I ensure your liner is properly installed, tested, and fully compliant.
-
This depends on your stove type and chimney condition. I install high-quality stainless steel flexible liners (316 or 904 grade) for most wood-burning and multi-fuel stoves. If your home doesn’t have a chimney, I can fit a twin wall flue system that safely vents through a wall or roof.
-
The cost depends on the type of liner, the height of your chimney, and any extra work needed. I provide free, same-day quotes with transparent pricing, so you know exactly what to expect—no hidden fees.
-
Flexible stainless steel liners are used for chimneys that already exist but need relining due to damage or inefficiency.
Twin wall flue systems are for homes without a chimney, allowing a stove to be installed with an insulated pipe venting through a wall or roof.
I’ll recommend the right system based on your setup.
