Many people think that it is the natural effect of an aging chimney, but want to check to make sure that it is not a sign of a larger issue.
White staining on the bricks of a chimney is called “efflorescence.” Unfortunately, efflorescence is a symptom of a larger chimney issue. If you are seeing white staining on the bricks of your chimney, it is best to contact a professional for an inspection.

Now, we’ll discuss what causes efflorescence and what to do actions you can take if your chimney has white staining.
Efflorescence is a white powder-like substance on the bricks of a chimney, which causes discoloration. This substance is actually a collection of minerals that forms as water passes through the bricks of the chimney and deposits them on the surface. When the moisture being held within the brick evaporates, it leaves the minerals’ crystals on the surface of the chimney, which is the white staining that you see.
Why is Efflorescence an Issue?
Small amounts of efflorescence are not a big deal, but excess staining is a sign that your chimney has water issues. After all, water should not be able to permeate your chimney’s masonry. If the bricks of your chimney are letting in moisture, then it is a sign that your chimney has an underlying issue. There are a host of reasons why this can be happening. Some of them include:
- Cracks in your chimney
- A missing or damaged chimney cap (the chimney cap plays in essential role in protecting your chimney)
- A chimney that is not well sealed
- Improper construction
- And more
