Repointing and Tuckpointing: Is There a Difference?

To provide you with a better understanding, the Masonry Magazine, the official publication of the Mason Contractors Association of America (MCAA), states that looking at the differences between the 100-year old definitions of the masonry terms “pointing,” “jointing,” “repointing,” and “tuckpointing” will give you a better idea of what repointing means today:

  • Pointing – The definition of pointing is the placement and careful tooling of a mortar joint between bricks and stones, and contrary to jointing, this process scrapes back the mortar joint several days after the completion of the brickwork.
  • Jointing – Jointing is what bricklayers do today, the process of finishing the joint along with the brickwork being completed.
  • Repointing – Typically the type of restoration work done on older mortar, 100 years ago, repointing meant replacing a failed mortar joint, which happened about once a century.
  • Tuckpointing – The word “tuckpointing” referred to a specialized application of pointing where the bricks were first sanded to a smooth surface and the original mortar joint is masked with a thin strip that matched the brick in color. Then, the joint was meticulously shaved down to match exactly the other joints in the chimney, and a fine, usually white mortar was tucked over the lines and finely manicured to look like no repairs had ever been done.

Today, “repointing” refers to repairing damaged mortar joints by filling in the gaps and holes created by water penetration, and “tuckpointing” refers to replacing deteriorated mortar with new mortar. The experienced and trained professionals at SirVent Chimney and Venting Service are able to provide both types of masonry restoration to repair spalling and other damage due to water penetration of your masonry and mortar joints.
