Throughout the lifetime of your home, there is a large possibility that you will need to perform some type of maintenance in order to keep its intricately designed and delicately balanced parts from leaking or becoming damaged. The chimney and fireplace area, including surrounding drywall indoors, are prone to damage from water.

Rusty Chimney Flashing

If you are experiencing water marks on your ceiling or on the walls near the chimney, it is worth your while to take a look at the integrity of your flashing.

To prevent water from seeping into the pores of the brick and allowing the water to enter into your home, applying water repellent to the entire area near where the water damage is occurring  is one way to go. Be sure that the water repellent that you select is breathable and will not trap existing vapors inside the brick. If you are looking to water proof a smaller area, using a hose and soaking the brick bit by bit from the bottom up, and waiting fifteen minutes every couple of feet, you may be able to pinpoint where the water is entering.
