Chimneys are neglected by many homeowners who assume they are safe from wear and tear. Chimney repairs are often necessary when problems arise with chimneys.

Following are a few reasons why your chimney may need repair.

Efflorescence or Discoloration of White

Efflorescence, or white discoloration or staining, is sometimes found on chimneys. Moisture build-up is the reason, and simple cleaning will not solve the problem. Excess moisture can lead to efflorescence, which causes the chimney to deteriorate over time, requiring repair. Do you need experts to visit your chimney condition?

Deterioration of mortar joints

It is also possible for mortar joints over time to become damaged, requiring quick repairs to prevent more extensive damage. The masonry of a chimney will deteriorate over time as mortar deteriorates, allowing higher levels of moisture to accumulate, causing the chimney to decay. This moisture can freeze within cracks in the masonry during the colder months. Upon thawing, that frozen moisture could cause even larger cracks and eventually result in a collapse of the chimney.


Neither your damper nor your firebox should ever be rusted, as excess moisture may cause rust to form. You may not see rust, but if you notice a damper that seals or doesn’t function properly, there is most likely rust present.

In addition to rust, cracks in flue tiles can also indicate serious problems.


If you notice pieces of masonry strewn around the base of the chimney, this could be a sign of spalling, which involves damaged exteriors of chimneys. In masonry, spalling occurs when moisture develops, causing the concrete, brick, or stone material to crack.


Over time, shaling can cause damage to your chimney’s flue lining. Seeing pieces of chimney tile in the fireplace, however, may indicate that shaling has taken place, but cracks in the flue lining are not always indicative of shaling. You should repair your roof if you see signs of shaling.
