The Small Cracks and Why They're Important: Colder months are approaching, and it's time to repair damaged masonry BEFORE major freeze thaw cycles begin. Your home's exterior is not something to be overlooked. In the world of masonry, an ounce of prevention is worth a pound of cure. Freeze-thaw weathering occurs when moisture trapped within masonry freezes and subsequently contracts. During freezing, the water expands, exerting pressure that leads to the mortar cracking or fragmentation of the outer brick or stone, a process known as "spall." With each repetition of this cycle, masonry has the potential to experience more severe cracking and spalling, contributing to its overall weathering. Through proactive assessment and consistent maintenance, you can preserve the beauty of your brick and stone while also averting the need for more extensive repairs in the future. In Pennsylvania, masonry structures are bound to experience deterioration over time, given our temperate climate. However, having a grasp of the various stages of damage and recognizing the right time for routine maintenance can help you proactively prevent major repairs, ultimately saving you time and money in the long term.
