What is a Spalled Brick?

Have you noticed falling or missing bricks from your chimney? This can be an issue called spalling. Spalling happens often to masonry chimneys, retaining walls, and more. Small cracks lead to bigger cracks, leading to significant deterioration that requires professional masonry work.

What Causes Spalling

Moisture penetrates the brickwork. Depending on your climate and the weather conditions, the exterior condition of your brick can deteriorate considerably over time. The masonry work suffers more in harsher climates. Colder climates cause spalling due to the rapid freeze and expansion during the winter months. Leaks can cause serious spalling. Pressure washers and careless sandblasting further damage your brickwork.

In some cases, the spalling has been caused by reusing older bricks during construction. Older bricks are more porous. These leaves them much more susceptible to moisture and damage. Be sure to use a quality licensed professional when addressing your chimney needs.

Fixing the Problem

If you have allowed your chimney to deteriorate for a long period of time, you may need professional contractors to inspect and repair your chimney. This can include costly work like an entire chimney replacement. Catch the problem before it reaches a crucial tipping point and you can save considerably. Your contractor may have to replace the crown or simply replace and seal the bricks. A chimney cap can add extra protection against future damage.

Preventative Measures

If your chimney is not damaged, take a few preventative steps to avoid damage. Yearly inspections can result in early detection for chimney issues. Monitor trouble spots. Apply masonry sealant to prevent additional issues. Install a quality chimney cap. Contact a professional if you find that bricks are falling or that there has been leaking and moisture in the brickwork.
