Did you know some chimneys are built with "dummy tiles"? These are empty tiles filled with bricks or concrete, typically used when a chimney is wide enough for two fireplaces but only one is in use. The problem is that dummy tiles often crack and fail, leading to water damage in your roof or home. At Chimney Doctors, we don’t install dummy tiles, and we always remove them during chimney rebuilds to ensure your chimney is safe and waterproof for years to come! 💪🏠
