Chimney Liner Installation

Yes, absolutely. Installing a chimney liner (typically flexible or rigid stainless steel) is a common and effective retrofit for older masonry chimneys. Many homes in Wisconsin have chimneys built decades ago with clay tile liners that crack, deteriorate, or were never present.

A professional can often drop the new liner down the existing flue to bypass damaged areas, improve safety, and restore proper venting—if the chimney’s sizing and condition allow it (e.g., the flue provides enough clearance for the liner plus required insulation without restricting draft or violating codes, and there are no major obstructions).

However, if sizing requirements don’t allow a proper fit (such as when the liner + insulation would be too tight, or if protruding mortar, offsets, or damaged tiles block the path), the original clay tile liner must be removed beforehand. This “breakout” process clears the flue for accurate sizing, better draft, easier insulation, and prevents future tile collapse that could damage the new liner.

A high-quality stainless steel chimney liner can last 30+ years when installed correctly. Factors such as burning dry, seasoned wood, preventing water intrusion (with a proper chimney cap), and avoiding chimney fires significantly extend its lifespan. In cold climates like Wisconsin, insulated liners perform better and last longer by minimizing condensation and corrosion. Cheaper or poorly maintained liners may fail much sooner, so we recommend using high-quality components from a reputable brand.

Not always mandatory for a well-maintained, code-conforming open masonry fireplace with intact clay tiles, but it’s often recommended (and sometimes required) for safety and performance. Unlined or damaged chimneys allow creosote buildup (leading to fires), carbon monoxide leaks, or poor draft/smoke spillage. Modern codes emphasize liners for wood fuel to contain combustion byproducts and protect against heat transfer to combustibles. Skip it only if your chimney passes a thorough inspection with no issues.

We always recommend opting for a 316Ti-grade stainless steel chimney liner (with insulation) as the best choice for wood-burning fireplaces. This grade of steel offers excellent corrosion resistance and durability, especially in cold, humid climates like Wisconsin where condensation and creosote can accelerate wear.

Stainless steel far outperforms traditional clay tile (which often cracks after 20–50 years) and cast-in-place. It’s highly durable, UL-listed for extreme temperatures, and significantly improves draft and efficiency (particularly when insulated).
