Sealing the structure helps prevent moisture damage, which can lead to issues like cracks, spalling, efflorescence, and damaged mortar joints.

For the best results, consult a chimney professional to select the right type of chimney or flue cap for your home. It's also wise to continue with annual chimney inspections to maintain the structure's integrity.
