01
What a Damaged Liner Does to Your Home
Clay tile liners crack from thermal stress, chimney fires, and the expansion and contraction that comes with decades of use. When a crack develops, hot combustion gases contact the surrounding mortar and masonry directly. Over time, that heat degrades the mortar, eventually reaching the wood framing inside the wall. Creosote can also seep through liner cracks and accumulate in areas that are not cleanable, creating a fire hazard that no amount of sweeping can address. Carbon monoxide from gas appliances and furnaces follows the same path through cracked liner sections. A damaged liner is not a cosmetic issue. It is a structural and safety failure.
02
When Relining Is Required
Relining is required when a Level II or Level III inspection reveals cracked, broken, or missing liner sections. It is also required when you change the appliance connected to the chimney, including upgrading to a new furnace, switching from oil to gas, or adding a wood stove insert. Older chimneys built before liner requirements were codified often have no liner at all and must be lined before any solid-fuel or gas appliance can safely vent through them. Real estate transactions frequently trigger the need for relining when a home inspection or buyer-required chimney inspection reveals liner damage.
03
Stainless Steel Liners for Wood and Oil
For wood-burning fireplaces, wood stoves, and oil furnaces, we install 316Ti stainless steel flexible liner systems. The 316Ti alloy is specified for these applications because of its resistance to the acidic condensates that wood and oil combustion produce. Each liner is sized to the appliance output and the height of the chimney using NFPA 211 calculations, not approximations. Proper sizing determines draft performance. An undersized liner restricts airflow and causes smoke spillage. An oversized liner slows flue gases, drops temperatures, and accelerates creosote buildup. We size every installation by the numbers.
04
Aluminum and Stainless for Gas Appliances
Modern high-efficiency gas furnaces and water heaters produce lower-temperature exhaust gases than older equipment. In an oversized clay tile flue, those gases cool before they exit, condense on the liner walls, and produce a mildly acidic moisture that destroys clay tile within a few seasons. We install aluminum liner systems sized specifically for the BTU output of the connected appliance to prevent condensation and ensure the gases exit before cooling to dew point. When the application requires it, we use 304 stainless steel as an alternative to aluminum for gas appliance venting.
05
The Relining Process
We begin with a camera inspection of the existing liner to document the damage and measure the flue dimensions. From that data we select the liner diameter and length. Installation involves attaching a top plate at the chimney crown, running the flexible liner through the flue from the top, and connecting it to the appliance at the bottom with a connector and thimble. We insulate flexible liner installations when the chimney wall thickness is less than the NFPA minimum, which improves draft and prevents condensation. Every installation concludes with a draft test and a written service record.

Chimney Relining Cost in Boise ID
Stainless steel liner installation for a standard residential wood-burning fireplace typically runs $1,500 to $3,000 depending on flue height, liner diameter, and whether insulation is required. Gas appliance liner installations generally run $800 to $1,800. Full-length liners in older two-story or split-level homes with taller chimney runs fall toward the higher end of these ranges. These figures cover materials and installation. If the existing appliance needs to be modified to accept the new liner connection, we include that in the written quote before work begins.
