Chimney repointing is the process of removing deteriorated mortar from masonry joints and replacing it with new mortar. It helps restore the condition of the joints, support the surrounding masonry, and reduce areas where moisture can enter.
Common signs include cracked, crumbling, recessed, or missing mortar between bricks. If the joints look worn or uneven, a professional chimney inspection can help determine whether repointing is needed.
Chimney flashing helps manage water around the area where the chimney meets the roof. Properly installed flashing directs rain and melting snow away from this transition and helps protect both the roofing system and chimney masonry.
Yes. When both the mortar joints and chimney-to-roof transition need attention, completing repointing and flashing work as part of the same project can provide a more complete exterior chimney repair.
Rain, snow, moisture, seasonal temperature changes, and repeated freeze-thaw cycles can gradually wear down chimney mortar and masonry. Routine inspections and timely repairs can help address deterioration before it becomes more extensive.
