What is brick repointing — and why it matters
Brick repointing is the process of renewing the mortar joints between bricks. In NYC, mortar fails from temperature fluctuations, weather exposure, and water infiltration — causing it to crack, crumble, and fall out. This compromises both structural integrity and weather resistance.
Repointing is common maintenance for older brick buildings and can extend masonry life by decades when done properly. The critical factor most building owners overlook: "repointing" is only half the work. Cutting out and removing failed mortar before replacement is imperative. Without proper joint preparation, new mortar won't bond or perform.
Why repointing fails — and how we prevent it
Inadequate Joint Preparation
Many contractors apply new mortar over deteriorated material. We cut joints to proper depth, remove all failed mortar, and ensure a clean substrate for mechanical bond.
Wrong Mortar Composition
Using mortar that's too hard for the brick can cause brick face spalling. We analyze existing mortar and specify preblended mixes matched to your masonry.
Water Infiltration Sources
Deteriorated joints allow water behind the wall. Freeze-thaw cycles then accelerate damage exponentially. We address both the joints and the water management.
Improper Tooling & Finish
Joint profile affects water shedding and longevity. We tool joints to match the original profile and ensure proper compaction for density and durability.
We're not prideful — we're exact.
Preblended mortar is the industry standard for a reason. Although experienced masons pride themselves on mixing their own blends, we reduce margins of error through best practices, quality materials, and meticulous work ethic.
Every repointing project begins with mortar analysis. We identify the existing mortar composition, specify a compatible preblended mix, and prepare joints to proper depth before any new material is placed. This isn't dramatic — it's methodical. And methodical work lasts.
