Types Of Chimney Damage That Require Chimney Repair

Chimneys direct smoke and combustion gasses from the fireplace, ensuring a warm and comfortable indoor environment when cold. However, chimneys may get damaged over time due to exposure to weather or old age. Hence, chimney repair may be necessary. Here are the common types of chimney damage that require repair. 

Creosote Accumulation

Creosote is a type of soot. The creosote may build up in your chimney if the creosote-containing wood undergoes incomplete combustion. The smoke may not rise fast enough to escape the chimney, and the creosote may settle inside. When layers of soot accumulate in the chimney, this may prevent combustion gasses like carbon monoxide from leaving through the chimney. This may increase the risk of respiratory diseases. 

Moreover, soot is highly combustible and may increase fire risks in your home. Fire outbreaks may result in property loss or burn injuries. Soot removal may be necessary to avoid these problems. Chimney sweep services may use tools like brushes to remove the creosote.


If your chimney bricks absorb water and are exposed to fluctuating temperatures in winter, the brick surface may crack. Eventually, the bricks may break and fall; this is referred to as spalling. Spalling may negatively affect your chimney's appearance. Also, the broken bricks may reduce its structural integrity, increasing crumbling risks. In such cases, chimney repair may entail replacing the broken bricks and applying water-repellent or waterproofing products on your chimney.

Mortar Deterioration

Mortar joins the bricks in your chimney. However, water seepage by the mortar may result in its disintegration. This may result in the loosening and eventual misplacement of bricks. Hence, some bricks may experience great pressure and crack. Chimney repair services may replace the damaged mortar and place the bricks back in the right position. The professionals also ensure that the newly repaired area blends in with the old parts maintaining the chimney's aesthetics.

Liner Damage

Chimney liners protect the masonry and the chimney's surrounding elements against heat damage. Additionally, the liner may prevent the corrosion of components like the firebox or damper by acidic gasses combined with moisture exposure. Nonetheless, your chimney liner may tear, reducing its efficiency. Chimney repair professionals can inspect your damaged chimney, identify liner problems, and provide quick, long-lasting fixes.

The common types of chimney damage that require repair include mortar damage, creosote build-up, and water and liner damage. Contact a local chimney repair service to learn more.
