If you notice any of the following, your chimney may need repair. These are the 5 signs that you should be aware of when looking at your chimney.
 
Efflorescence or White Staining
White discoloration on a chimney is called efflorescence.  Efflorescence is an indication of excess moisture in the masonry.  If it isn’t addresses with promptly, it will definitely expedite deterioration of the chimney.
 
 
Deteriorating Mortar Joints
We live in beautiful New England, but unfortunately for brick and mortar, that means exposure to all 4 seasons and accelerated masonry break down. The arch nemesis for brick work is the freeze/thaw cycle during later winter through early spring.  This leads to rapid break down and water leaks.
 
Chimney Crown Damage
The top of the chimney where your rain cap sits is called a crown or wash.  Sometimes you can not see the top of the chimney so this may require getting on the roof to check the condition.  The crown of the chimney is an important part of the structure, because it is generally the highest point of your home, and that means it’s the first to get all the weather elements (snow, wind, rain, hale).  A cracked crown is one of the most common reasons for a leaky chimney.
 
 
Spalling
Spalling occurs to the outside of the chimney and can be identified if you see bits of masonry around the bottom of the chimney.  When moisture enters masonry, it can force the surface of the brick to pop out, crumble, or flake. Damaged masonry should be attended to right away to prevent continued crumbling.
 
 
 
Damaged Wallpaper/Water Stains
Bubbling wallpaper on the walls or water stains on the ceiling near the chimney provides a clear sign that there could potentially be an issue with your chimney.  There could be a number of water entry points when it gets to this point, but often, a combination or masonry and/or flashing repairs, raincap installation, and waterproofing will remedy the leakage.
