Spring time in the Northeast can bring us steady and heavy rains at times. Water leaks and water damage in and around the chimney can be a mystery to solve. Brick and mortar are very porous overall. Over time water absorption through rain or snow is usually the common cause for water leaks in and around the chimney, or as seen in the fireplace. The more obvious signs of water damage can be seen in the attic area, if the chimney passes through the home centrally. More often a white powdery substance called efflorescence can be found on the exterior of a chimney. in and around the fireplace hearth area and again on the outside of the brick as seen in an attic.
Resolving Water Leaks and damage may involve inspecting the lead/sub flashing, observing wood near the chimney for water stains, and maybe even mold damage due to consistent or steady water penetration.
Being successful when dealing with water could require a combination of repairs. the following are some or the ways that may be necessary to correct water penetration:
A. A chimney cap; installing a chimney cap with the proper lid can cover the surface area of the top of the chimney which can greatly prevent water absorption.
B. Grinding and re-pointing the chimney with new mortar can help immensely.
C. Spray on application of a water repellent containing the chemical Siloxane (the main ingredient in the top water sealing products today)
D. Repairing or replacing lead/step flashing in and around the chimney.
