Repointing & Tuckpointing | Mortar Joint Repair
Repointing involves removing and replacing deteriorated mortar joints to restore the strength and weather resistance of a masonry building. Tuckpointing is often used to describe the same work with added attention to the appearance of the joints, most commonly on historic or decorative façades. At BRC, our approach focuses on proper repointing practices that protect the structure and extend the life of the masonry.
Our craftsmen work with both historic and modern buildings, using carefully selected mortars that match the original materials as closely as possible. By evaluating each façade and its condition, we apply the right solution to preserve the building’s character while delivering reliable, long-lasting performance.
Mortar Removal
Mortar removal is the process of removing the deteriorated mortar using the most sensitive means possible based on the materiality of the façade. At BRC we allow the building to inform us on the best mortar removal method for each project. We employ pneumatic or electric saws, grinders, and chisels on our projects, as well as the “center cut method” and hand chiseling where applicable. Mortar removal depth is also carefully considered and is project specific based on the depth of deterioration or the specified requirements of a project.
Repointing & Mortar Selection
A successful repointing project must consider all the material compatibility requirements based on the original materiality of the masonry wall. Our management team and skilled masons understand the importance of mortar compatibility when selecting a mortar for any project.
It is imperative to consider the material properties of the masonry units as well. The mortar must be softer and more permeable than the masonry units, while also replicating the performance and aesthetic properties of the original mortar itself. We follow the guidelines of the National Park Service as presented in Preservation Brief #2 “Repointing Mortar Joints in Historic Buildings.”
FAQs
Do we need tuckpointing or repointing, and how can you tell which one our building needs?
Technically speaking there is a big difference between the words “tuckpointing” and “repointing.”
Tuckpointing is an old joint repair method that involves pointing in a lime mortar that matches the color of the surrounding brick, then coming back through and striking in a thin white lime mortar bead that mimics the appearance of narrow “butter joints” commonly seen in historic masonry buildings in Europe. Here in the US we don’t typically do tuckpointing in its traditional sense. Over the years the term “tuckpointing” has evolved into the common nomenclature for mortar joint replacement in the United States.
Repointing refers to the process of removing original failed mortar back to sound material and pointing in a replacement mortar that matches the original in material properties, aggregate profile, color, texture and profile.
Long story short, in the United States (for the most part) TUCKPOINTING = REPOINTING and the words are often used interchangeably. The short answer is it depends on the condition of the existing mortar. During an on-site evaluation, we look at depth of deterioration, cracking, and moisture issues. We walk you through what we see and explain the best long-term solution for your building.
How much does repointing (tuckpointing) cost per square foot for a multi-story brick building?
Costs can vary widely based on access, height, mortar condition, joint size, and the amount of preparation needed. Multi-story buildings often require scaffolding or swing stages, which affects pricing. After a site visit, we provide a clear, detailed proposal so you understand exactly what is included and why.
Can you match our existing mortar color and joint style so repairs blend in?
Yes, and this is something we take very seriously. We analyze the existing mortar material properties, color, texture, and joint profile, especially on older or historic buildings. Our goal is for repairs to blend naturally so they do not stand out or change the character of the façade. Equally important to a successful repointing project is that we repoint with a mortar that matches the material properties of the original mortar that we are repointing over top of.
