Chimney repairs span from the firebox up to the chimney stack's summit.
The firebox, subjected to intense heat, gradually experiences wear. Despite the firebricks' heat-resistant composition, they can deteriorate, potentially leading to flaking so repair or replacement becomes necessary. Yet, it's typically the mortar that succumbs to degradation first. Rectifying this issue involves a technique known as repointing.
Repointing entails a specialized masonry craft. The procedure involves removing deteriorated mortar from the joints of a brick wall and substituting it with fresh mortar to enhance robustness and endurance. This technique is applicable both internally within the fireplace and externally on the chimney stack.
