Major repair · 1–2 day job

Chimney relining is a vital chimney repair service that restores safety, improves performance, and brings damaged or outdated flue systems back into proper working condition. The chimney liner is the internal pathway that safely vents smoke, gases, and heat out of the home. When it becomes cracked, deteriorated, or is no longer present, the chimney can become unsafe to use.

A properly functioning chimney liner protects surrounding wood framing from excessive heat, helps prevent carbon monoxide from entering living spaces, and ensures proper draft for your fireplace or appliance. Many older chimneys were built with clay tile liners, which can break down over time due to chimney fires, moisture intrusion, freeze–thaw cycles, or long-term wear.

When a chimney liner is compromised, homeowners may notice symptoms such as poor drafting, smoke entering the home, strong odors, or visible damage found during inspection. In more severe cases, gaps or cracks in the liner can allow dangerous heat transfer to nearby combustible materials, increasing the risk of a chimney or house fire.

Chimney relining involves installing a new stainless steel liner inside the existing chimney structure to create a smooth, durable, and code-compliant flue system. Stainless steel liners are highly corrosion-resistant and suitable for wood, gas, and oil-burning appliances, offering long-term safety and performance.

A properly installed liner restores safe venting, improves efficiency, and ensures the chimney meets current building and safety standards. In many cases, relining is more cost-effective than rebuilding the chimney structure while providing lasting protection for your home.

Because liner damage often occurs out of sight, professional inspection is essential. A video scan of the flue helps identify hidden cracks, separation, or deterioration so issues can be addressed before they lead to costly damage, fire hazards, or carbon monoxide risks.

Frequently Asked Questions

How do I know if my chimney liner is damaged?
A Level 2 video inspection is the only definitive way to assess liner condition. Warning signs that should prompt an urgent inspection include a chimney fire (any past event, even a minor one), visible cracks in the exterior masonry, carbon monoxide detector activations, smoke or fumes entering the living space, or an older home with no knowledge of the liner's history. Many liner failures are not visible from the firebox.
Is relining required by code?
NFPA 211 and the International Residential Code both require a continuous liner for solid-fuel, gas, and oil appliances. Many homes built before the 1940s have unlined masonry chimneys that are technically out of code. Additionally, any time an appliance is replaced or upgraded — particularly when switching from a wood-burning fireplace to a gas insert — the liner must be inspected and often replaced to match the new appliance's exhaust requirements.
What is the difference between a stainless-steel liner and cast-in-place?
A flexible stainless-steel liner is a pre-fabricated continuous tube lowered into the existing flue and insulated with a poured vermiculite backfill. It is faster to install and the most common solution. Cast-in-place involves pouring a castable refractory material directly inside the existing flue to create a new seamless liner — ideal when the existing tile structure is sound but the inner surface is damaged. Both meet UL 1777 and are CSIA-approved methods.
How long does a chimney relining job take?
Most residential relining jobs complete in one to two days. The appointment begins with a Level 2 video inspection and a written quote. Stainless-steel liner installations are typically one-day jobs. Cast-in-place systems require additional cure time and may take two days.
