What Is a Chimney Liner and Why Does It Matter?
A chimney liner is a conduit inside your chimney that safely contains and vents combustion gases and heat from your fireplace or heating appliance to the outside. It protects your home's structure from heat transfer and prevents combustion gases — including carbon monoxide — from leaking into living spaces.
California and Sacramento building codes require a properly sized, intact flue liner for all wood-burning fireplaces and gas appliances. Most Sacramento homes built before 1950 have clay tile liners that deteriorate with age, especially after chimney fires or years of seasonal use.
Types of Chimney Liners We Install
Stainless Steel Flexible Liners: The most popular choice for Sacramento homes. Can be installed in chimneys with bends and offsets. Available in rigid or flexible forms. Suitable for all fuel types. Comes with 20-year manufacturer warranty.
Cast-in-Place Liners: Ideal for older Sacramento masonry chimneys with irregular shapes. A poured insulating compound creates a new smooth liner inside the existing flue. Excellent for structural stabilization.
Aluminum Liners: Used for Category I gas appliances only. Lightweight and cost-effective for simple gas vent conversions.
