Tuckpointing or Repairing Mortar Joints
A good rule of thumb is every 20-30 years a masonry chimney’s mortar joints will need to be cut-out, cleaned and refilled with fresh mortar–a process known as tuckpointing or repointing.
Removing the old mortar during chimney repointing is a time-consuming, but necessary step in this process because it ensures a long-lasting repair. Unfortunately, we see numerous chimneys in our service area that have simply been “ribbon pointed.” Ribbon pointing refers to merely coating old deteriorating mortar with new mortar. A ribbon pointed chimney will require repointing in just 5-7 years whereas a properly repointed chimney will endure for decades.
If the mortar joints in your chimney have gaps, cracks or show visible deterioration, call Chadds Ford Chimney Sweeps for a solid repointing solution.
