Chimneys and brick masonry can withstand a lot of wear and tear, especially when it comes to rain, snow, and extreme cold. Water can cause significant damage to brick and masonry chimneys, which may come as a surprise. Water seeping into the brickwork and eroding the grout, or perhaps harming the brick itself, is what we're talking about. When water seeps into and between brick masonry work and then freezes, it poses the greatest danger. When water freezes, it expands somewhat, which can cause bricks to move away from one another. As a result, more water can get deeper and deeper into your chimney brickwork, causing additional damage – to your chimney, as well as your attic, insulation, and beyond. All of this can be avoided by waterproofing your chimney. While we don't advocate this service for every chimney, it does make sense in some cases. Waterproofing can save you money by preventing costly repairs to chimneys, brickwork, and masonry that have been damaged by water or freezing temperatures.
