    Have you ever noticed a white buildup on your chimney? If so, your home may by experiencing a common problem called efflorescence. While this powdery substance is unsightly, it can also be an indicator of large moisture problems inside the flue. Below we breakdown everything you need to know about this common chimney annoyance.

    What is efflorescence?
    Efflorescence is a crystalline deposit often found on masonry surfaces such as chimneys, fireplaces, and home exteriors. These deposits form when water penetrates the porous surface of the brick. When the water evaporates, the salt from the water is left behind leaving the white film. Efflorescence can occur anywhere where brickwork is exposed to moisture.

    How do you get rid of efflorescence?
    There are steps you can take to remove efflorescence from your brickwork. If the buildup is fairly fresh, it may simply take some elbow grease and a dry brush to sweep the surface clean. You can also try letting Mother Nature work her magic and allow the natural weathering process to take effect. For smaller areas, hand-cleaning the area with mild detergent and a small bristle brush can work wonders. Some may suggest sandblasting the area. Although this method will work to remove the efflorescence, it will unfortunately also remove the surface of the brick as well leaving it more prone to the same problems in the future. Keep in mind that although you can often easily remove the buildup, if you don’t address the underlying issue, water entering the brickwork, efflorescence will return again.

    How do I prevent efflorescence?
    While it is difficult to eliminate all occurrences of efflorescence, you can lessen the likelihood of them appearing. The main way to do this is by eliminating the ability for water to enter through the chimney. One of the best ways to prevent efflorescence is to seal the brickwork especially if it is older and shows signs of deterioration. It is also important to repair any major chimney crown issues such as insufficient flashing.
