If one section of brick is starting to crumble, is it likely to spread across the wall & if so how fast is it likely to spread?
Answer
It can. Once water starts getting into one area, it often works its way into nearby bricks too. How fast it spreads depends on how much water is getting in and how bad the damage already is. Sometimes it gets noticeably worse after just one winter, while other times it takes a few years. The sooner it’s fixed, the better chance you have of keeping the repair smaller and less expensive. It’s much easier to replace a small damaged section than wait until a larger area starts breaking apart. Many homeowners are surprised by how much hidden damage is found behind a section that initially looked minor.
