The Top 6 Signs It’s Time to Repair Your Chimney

Chimneys, like all areas of our homes, need to be repaired at some point in time. But how do you know if that point in time has finally come? Below are some of the most common signs that your chimney should be repaired sooner rather than later:

Rusted Damper or Firebox

The Top 6 Signs It’s Time to Repair Your Chimney

When moisture seeps into your chimney, it can rust out your damper or your firebox. Rust can usually be spotted easily, but sometimes it’s not so obvious. If you have difficulty opening your damper or notice your flue tiles have cracked, these could be other signs of a rusted damper or firebox.

Broken Tiles or Ceramic Pieces in Your Fireplace

Have you noticed bits and pieces of tiles or ceramic in your fireplace? Then this could be a sign that your flue liner is shaling. Flue liner protects your home from catching fire. As such, if you continue to use your chimney in this state, you could cause a house fire.

Cracked Chimney Crown

The top part of your chimney is called the chimney crown. When this is cracked or damaged, rain, debris, and other natural elements can get inside and cause further harm to your chimney. Keeping your chimney crown in good condition is essential in preventing costly chimney repairs later on.

Spalling Bricks

Spalling is when water seeps into your bricks, causing your masonry to peel off or pop out. Not only does this ruin the look of your chimney, but it can also leave it vulnerable to the natural elements.


Excess moisture can cause a whole host of problems in your chimney, but the most obvious is staining. Stained ceilings or walls are a sign that your chimney is absorbing too much moisture for its own good. Additionally, white staining or efflorescence on your chimney’s exterior is also a sign of water damage.

Damaged Mortar Joints

Damaged mortar joints can be difficult to spot, mainly because you have to be up on your roof to see them. However, if you have hired a chimney company to perform routine maintenance on your chimney, they will spot the problem before it gets too serious.
