Re-Pointing Chimney Walls and Stone Walls
Even rock masonry can become damaged, due to excess moisture caused by deteriorating mortar joints. Ultimately, moisture in the chimney causes a large variety of problems, inside and outside of the home, which can be expensive to repair and which can render a chimney unsafe to use until those repairs are made. Many times “re-pointing” can put a stop to the destructive process.
If a chimney is subjected to extreme amounts of water on the roof, it’s best to install accessories which divert the water away from it. Whatever the conditions, mortar on a masonry chimney/wall eventually needs to be replaced, which is achieved by re-point.
Re-point is a repair process which replaces damaged mortar joints between masonry materials.
