Repointing, in the context of building restoration and maintenance, refers to the process of replenishing and restoring the outer layer of mortar joints on brick and stone structures. Over time, the elements and natural wear and tear can cause the mortar to deteriorate or become unsuitable, resulting in gaps or weaknesses within the joints. Repointing aims to rectify this by carefully removing the degraded mortar and replacing it with a new, more durable mixture. It’s a meticulous craft that requires expertise and an understanding of the historical context of the building, as many older structures have undergone multiple repointing efforts using different mortar mixes and styles. Proper repointing not only improves the structural integrity of the building but also enhances it’s aesthetic appeal, preserving the architectural heritage for future generations.
Why Is Repointing Necessary?
Repointing is necessary for several reasons. First and foremost, deteriorated or damaged mortar can weaken the overall structure of a building. Mortar acts as a binding agent between bricks or stones, providing strength and stability. Over time, exposure to weather elements, such as rain, sun, and frost, can cause mortar to deteriorate, resulting in weakened joints. By repointing, masons remove the compromised mortar and replace it with fresh mortar, reinforcing the integrity of the structure.
Another reason why repointing is necessary is for the maintenance and longevity of historic buildings. Many old structures are made with lime-based mortars, which are softer and more flexible than modern cement-based mortars. As these historical buildings age, lime mortar can gradually erode and deteriorate. Repointing with a compatible lime mortar helps to preserve the authenticity, historical significance, and longevity of these precious architectural treasures.
Lastly, repointing can be a cost-effective alternative to completely rebuilding a damaged masonry structure. If the damage is localized and the majority of the building remains in good condition, repointing specific areas can restore the structural integrity without the need for a full-scale reconstruction. This saves time, money, and resources while still ensuring the stability and durability of the building.

Repointing a stone house can come with a price tag depending on the size and scope of the project. The cost can range anywhere from $3 to $20 per square foot. For chimney repointing specifically, homeowners can expect to pay around $500 to $2,500. If you’re considering tuckpointing, which is a technique that involves using contrasting colors of mortar to create the illusion of finer joints, the cost can vary between $5,000 to $40,000 for a brick house. On a smaller scale, repointing an 8’x10′ wall can cost anywhere from $250 to $2,000.
How Much Does It Cost to Repoint a Stone House?
The cost of repointing a stone house can vary depending on several factors. One of the major factors is the size of the area that needs to be repointed. Repointing brick or stone can range from $3 to $20 per square foot. For a larger project, such as repointing the entire exterior of a brick house, the cost can range from $5,000 to $40,000. This is because it involves a substantial amount of work and materials.
Another factor that can impact the cost is the condition of the existing mortar. If the mortar is severely deteriorated or damaged, it may require additional work and materials to properly repoint the house. This can increase the overall cost of the project.
Chimney repointing is also a common task that many homeowners undertake. The cost of chimney repointing can range from $500 to $2,500, depending on the size and condition of the chimney. Chimneys are often exposed to harsh weather conditions and can deteriorate more quickly than other parts of the house, so regular maintenance is important.
If you need to repoint a smaller area, such as an 8×10 wall, the cost can range from $250 to $2,000. This is because the scope of the project is smaller, but the materials and labor required are still necessary.
It’s important to get multiple quotes from qualified contractors to ensure you’re getting a fair price. Additionally, regular maintenance and inspection of the mortar joints can help prevent more extensive and costly repairs in the future.
Conclusion
It involves replenishing the deteriorated or unsuitable mortar in the joints to enhance structural integrity and aesthetic appeal. The presence of various mortar mixes and styles used in different repointing instances on these buildings testifies to the long history of maintenance and care they’ve received. Repointing ensures the longevity of these architectural gems, safeguarding their beauty and character for generations to come.
