This picture is an example of a neglected chimney which over the years has been allowed to absorb water and the results are the damaged joints and the destruction of the whole chimney.This chimney will require a professional to set up staging, cut out loose and bad mortar joints and then apply new mortar to the joints. There are many clear sealers on the market, they all proclaim to be the best, use my product, but when you read the fine print they all work best when applied to a sound surface. Clear sealers cannot take the place of mortar and sound solid bricks. Clear sealers, the active solids left behind in the pores of the masonry can only work properly when the mortar joints are tuck pointed tightly and the bricks don’t have spalling faces and the roof cap cannot have mortar missing. The roof flashing must be in good shape or sealing your chimney will only stop some of the water. For more information on Chargars clear masonry sealers go to www.chargar.com or call 1-800-922-4623.
