How do I fix a gap between my house and chimney?

Our outside brick chimney has been stabilized but now has a 1/4-inch crack on both sides against the house. How do I neatly close the cracks? I’ve been told I must use a product that will withstand rain without being painted.

If the gap is only a ¼-inch wide, you can use a masonry caulk found at most home center stores. It will adhere well to both the brick and the siding of your home, and it will withstand the differential movement of the different building materials.

Make sure that you clean out the crack and the area around it before you fill it. You can use masking tape if you want to keep your lines straight.
