Chimney Liner Replacement

Chimney Liner Replacement — Restore Safety and Performance

A damaged chimney liner is one of the most serious chimney deficiencies. The liner contains combustion products, prevents heat transfer to nearby combustibles, and blocks toxic gases from leaking into your home. When your liner fails, replacement is urgent. At Chimney Repair Group, we provide expert liner replacement using the highest quality materials available.

When Liner Replacement Is Necessary

Liner replacement is needed when: inspection reveals cracked, separated, or deteriorated clay tiles; an existing metal liner has corroded through; the chimney is unlined (common in pre-1940 homes); you're changing fuel types (oil to gas, or adding a wood stove); or after a chimney fire that damaged the liner.

Our Replacement Process

We begin with a thorough inspection to document existing liner condition and chimney geometry. Based on findings, we determine whether the old liner needs removal or can be left in place with the new liner installed inside. We use premium 316Ti stainless steel — the highest grade available, resistant to all fuel types. Each liner is sized precisely for your appliance and chimney height to ensure optimal performance.

Insulation for Maximum Performance

We insulate replacement liners with high-temperature vermiculite blankets for wood-burning applications and recommend insulation for all fuel types. Insulation maintains higher flue gas temperatures for better draft, reduces condensation, and provides an additional safety barrier. It's a critical addition that dramatically improves liner performance.
