What is the White Stain on my Chimney?

Over time if you notice white staining on your chimney, you may think nothing of it and just assume that it's the signs of the chimney aging. However, if you do see a white residue on your chimney, you should be concerned as this is a sign of water damage. If left untreated, this will lead to excess damage and deterioration of the chimney. Water is the number one enemy of chimneys so it's important to combat any issues that may arise from water. Therefore, you shouldn't wait to get a Chimney Cleaning in York PA this fall.

Known as efflorescence, the white powder is created by soluble solutions moving through the chimney leaving behind salt residue. The residue then dries and becomes a powder substance that is found on the outside of stone, brick or cement block. Excess water will try to enter the structure by any means possible so the smallest crack will cause water to enter the chimney and cause damage. If a cap is missing or damaged, flashing is insufficient or there are cracks in the motor, water will enter and will create efflorescence. The deposits themselves are mostly cosmetic but are a big red flag indicating that there is a larger issue at hand.
