Whenever you have any masonry repair done on your chimney it is important to seal the brick and mortar upon completion. We waterproof masonry chimneys with Chim-Saver water repellent. It is the best waterproofing product available for chimneys and is a 10-year sealant. A properly built, properly maintained chimney will last a lifetime. Chim-Saver water repellent is applied to “older” chimneys as well.
If you can’t remember when your chimney was last waterproofed, now is the time. It is the best thing you can do to help extend the life of your chimney.
