Question DetailsAsked on 7/18/2012

My chimney leaks in attic through mortar/brick when it rains. Is there a product to seal outside brick or another method to fix?

I have had flashing replaced but chimney still leaks. It drips out of mortar between bricks in several locations around chimney. My chimney is 20 years old and wondering if there are cracks or lost mortar on chimney letting water seep in. What can you do about this and who does this kind of work? I have heard about products to spray to seal brick. If so what is best to use and will last the longest?

You need to make an appointment with a mason to take a look at the chimney and possibly to perform a water test to determine the source of the leak. Most likely the chimney needs to be repointed to seal the cracks in mortar and then the masonry sealer could be applied to the entire chimeny to prevent future leaks.

Solving chimney leaks can be difficult as there are many potential spots that could cause the leak. Have a certified chimney sweep inspect the chimney and make recommendations. Leaks may come from the chimney crown, through the flue opening/cap, through the brick, and the flashing is always a potential leak. Sometimes a leak can occur without visible problems making the correct fix hard to identify. Find a certified chimney sweep in your area at the link below.

Please keep in mind if water is escaping these mortar joints,Then there is a good chance that this is also an escape for fumes,smoke, And even fire in the event of a chimney fire. Is There a chimney cap installed currently ? The structure needs to be sound before applying any waterproofing.

Good Luck,
