Repairing flashings that have been tarred over, split, cracked, or are in disrepair is easy with FlashSeal. It’s like installing a custom-fit rubber boot at the base of the chimney! It remains permanently flexible and has a 7 year warranty when used with FlashSeal Reinforcement Fabric.
For complete chimney protection, we recommend waterproofing the chimney and sealing the chimney crown.
