One crucial step in chimney maintenance is sealing the chimney crown to prevent water damage and extend its lifespan.

Why Do You Need a Chimney Crown Sealer?

The chimney crown is the topmost part of your chimney that acts as a shield against weather elements such as rain, snow, and wind. It also prevents animals and debris from entering your chimney.
