A tight chimney seal and waterproofing chimney is the best prevention for water damage into your home. Over time, concrete grout and brick will open up and allow rain water to enter the chimney and fireplace. Waterproofing chimney costs are minimal compared to the damage avoided. A chimney seal is your best defense for water damage.
This water will do substantial damage to the framing and structure of your living areas if not checked and stopped. A chimney inspection by a qualified and honest chimney company will uncover areas that can create issues in the near future.
Degraded grout and brick allow water to enter the chimney cap area. Chimney seal is the key.
Elbow grease is required to dig out the old cracked and dried grout. Repointing the chimney with new grout and fixing any broken or chipped bricks solves the water problem. After all of the entrances of water are blocked, the entire structure is waterproofed with a coating designed to last upwards of 10 years. Waterproofing chimney structures is a wise investment for your home.
A well done chimney seal will last for a decade or more. During your annual chimney sweep inspection, any issues with water or cracks will be corrected. This includes the chimney flashing area also. Water finds its way into any small openings, even if they are not obvious.
