Chimney Lining

What is chimney lining?

Chimney lining is when we install a protective sealed lining inside the chimney to contain the gases produced by the combustion process inside your fireplace or stove.

The liner creates a smooth pathway for the smoke and gases to exit the building whilst protecting the structural integrity of the chimney itself and the surrounding rooms/building materials that it passes through.

Why does my chimney need to be lined?

Safety: The liner prevents hazardouse gases like carbon monoxide, from leaking into the home and reduces the risk of chimney fires by containing creosote buildup and high temperatures within a containable enviroment.

Chimney Protection: The liner itself shields the brick chimney from extreme heat, acidic combustion byproducts and moisture which can cause cracks, deterioration and spalling.

Cost Effective Efficiency: A properly sized liner ensures optimal draft which will greatly improve the performance of your heating appliance which in turn reduces energy waste and the need for excessive spending on fuel.

Building Regulation Compliance: Many new buildings require a liner for new chimney installations or when you are replacing an existing damaged liner to meet current safety standards.

Preventing damage to life and the home:
Without a liner, heat and gases can seep through the cracks and missing mortar joints within an old brick chimney and escape into living spaces where it can be a danger to life as well as potentially damaging internal walls, ceilings and structural components.

When is chimney lining required?

New chimneys: To meet safety and building regulations outlined in Document J of the building regulations guide

Fuel type/Appliance changes: Switching to a new appliance (e.g switching from a gas fire to a wood burning stove) will require a liner of differing size and type due to the effects of an increase/decrease in working temperature

Old, Damaged or Chimneys in Disrepair: If the existing liner is damaged, flaking, unfurled or has holes within or if your brick and mortar chimney has missing mortar joints or ingresses into the internal space within.

Chimney Issues: Worrying signs like excessive creosote buildup, smoke leaks or visible damage tot he masonry of the chimney itself


We are able to perform chimney liner inspections using state of the art cctv rod systems which allow us to feed a HD camera up inside the liner to inspect for damage and then advise how to proceed based on our findings, not every liner will be damaged or has to be replaced before use and we will always strive to work on an as and when required basis.
