Firebox Rebuilding and Repointing
Over time the mortar joints in your firebox can wear and crack, leaving the combustible building materials in your walls much less protected against heat and embers. A leaky chimney letting water into the firebox can also speed up the wear and tear of your firebox. With minor damage to mortar joints, repointing can often solve the problem. However, if there is significant damage present, the safest and most effective solution is a rebuild or partial rebuild.
