Signs You Might Need a New Chimney Liner

Your chimney liner and chimney work together to protect your Central Virginia home and family safe while you’re enjoying the warmth of a fireplace. The chimney liner is a critical safety component protecting the masonry from the high heat and flames from the fireplace.

Damage to the Chimney Liner

When the chimney liner is damaged due to its age, moisture, wear and tear or other issues, there is increased risk of the intense heat spreading to nearby combustible building materials, such as the attic or a wood-framed chimney chase, that can cause a house fire. A damaged liner can increase the risk of exposure to dangerous carbon monoxide fumes.

It’s often difficult for homeowners to assess the condition of a chimney liner without a professional chimney inspection.

There are a few signs that indicate your chimney liner needs to be replaced. If you see any of these call us today to schedule a chimney inspection.

Moisture and Condensation: How does it Happen?

Clay tiles found in many chimney liners are porous materials that weaken when exposed to moisture or condensation. For example, a chimney leak due to worn flashing or cracks in the masonry or chimney crown can expose the chimney liner to water damage when it rains. This moisture in turn weakens the chimney liner which can cause further cracking.

Also, when the warm interior air mixes with the cold exterior air, the clay tiles in the chimney liner chimney liner can sweat, resulting in condensation if there are any cracks in the masonry and liner. Both are signs that indicate that a chimney liner replacement may be necessary.

Why is there Clay Material in the Firebox?

Having Clay material in the firebox is an issue you find with older homes. Many older homes still have the original clay tile chimney liner that has exceeded their expected 20-to-30-year lifespan. Adding to this, creosote buildup, moisture, and a chimney fire can damage the liner causing the clay tiles to flake, crack and burst, accelerating its deterioration.

This issue can shorten the lifespan of a chimney considerably. You may notice flakes or chunks of clay material in the firebox when this occurs. As the chimney liner continues to deteriorate, the risk of fire and exposure to carbon monoxide also increases, making it unsafe to operate your fireplace or heating stove.

New Chimney Liner, Fireplace or Insert Installation

Chimney liners must meet the manufacturer’s specifications for the heating appliance to operate safely and meet building code regulations. Anytime you are converting from one fuel type to another or installing a new fireplace or insert, the chimney liner will need to be replaced following the specifications for your new heating appliance. Installing a new fireplace with an existing chimney liner that doesn’t meet the manufacturer’s specs can result in performance and safety issues.

Your chimney liner is an essential safety component for protecting your home and family from a devastating fire and exposure to harmful fumes. A chimney inspection is the only way to determine whether it’s time to replace your chimney liner. That’s why we at Black Goose Chimney Service encourage all homeowners to have annual chimney inspections. A chimney inspection is a top-to-bottom interior/exterior visual examination of the entire chimney system, including the chimney liner, vents, and attached heating appliances.

When a chimney liner replacement is necessary, we typically recommend UL-listed stainless-steel liners for improved energy efficiency, fewer chimney repairs, and long-lasting durability.
