What brick pointing actually is
"Pointing," "repointing," and "tuckpointing" all refer to the same essential job: removing failed mortar from the joints between bricks and replacing it with new mortar. The bricks themselves usually stay put. The mortar is the part that wears out.
Mortar joints are the building's primary defense against water. They are also designed to be sacrificial — meaning they are intentionally softer than the bricks around them, so that as the wall expands and contracts seasonally, the soft mortar gives way before the hard brick does. When the mortar fails, water enters the wall, and the damage cascades from there.
Repointing is the most cost-effective single intervention available to a NYC building owner. A properly repointed wall stays watertight for 40–60 years.
Why the mortar mix matters
This is the part most contractors get wrong. They use whatever bag of mortar mix is on the truck, which is usually a Portland-cement-heavy blend designed for new construction.
Here is the problem: Portland cement is harder than the soft historic brick used in most NYC buildings built before 1930. When you point soft brick with hard mortar, the seasonal expansion-contraction cycle pushes against the brick instead of the joint. The brick face — not the joint — is what fails. You get spalling brick faces, popped corners, and accelerating deterioration. The "repair" actively damages the building.
The historically and structurally correct approach for pre-1930 NYC brick is a lime-based or lime/Portland-blend mortar, mixed to be softer than the brick and the same color as the original joint. This is what we use. We do not use bagged mortar mix on a historic facade. Period.
The 5-second test
Look at a building where someone has done a "modern" repair on old brick. The new mortar is bright gray and the brick faces are blown out around the joints. That is hard mortar destroying soft brick. It is everywhere in NYC. We replace this work for clients regularly.
Our brick pointing process
Six steps, every time.
1. Joint assessment
We check the depth and condition of mortar joints throughout the wall. Sound joints are left alone. Failed or compromised joints — the ones that crumble under a screwdriver — are flagged for replacement.
2. Selective joint cutting
Failed mortar is removed to a depth of typically 3/4" to 1" using hand chisels or carefully controlled grinders. We do not over-grind, which damages the brick face. We do not under-cut, which leaves the new mortar nothing to bond to.
3. Mix and color match
Mortar is mixed in small batches on-site. The mix is appropriate to the building's age and substrate (typically Type N or Type O for historic, with lime). The color is matched to the existing joint by adjusting sand, pigment, and lime ratios.
4. Pack and tool
New mortar is packed into the cleared joints in two passes (initial fill, then top coat). Once the mortar is "thumbprint hard" — meaning it holds an impression but is not wet — we tool the joint to match the original profile (concave, V-joint, raked, etc.).
5. Cure and protect
New mortar is misted with water as it cures (especially in summer) to prevent flash-drying, and protected from direct rain and sun for the first 48–72 hours. Cure time is 7–28 days depending on conditions.
6. Cleanup and inspection
Excess mortar is cleaned off the brick faces using soft brushes — never acid washes that can damage the brick. We walk the wall with you to confirm the work and color match.
What pointing costs
Pointing is priced primarily by square footage of wall and the percentage of joints that need replacement. Typical NYC ranges:
Spot pointing
$3K – $12K
Selective repair of failed areas only — typical for buildings in good general condition.
50% repointing
$15K – $40K
Half the joints replaced on a typical four-story brownstone. Common.
100% facade repointing
$30K – $80K
Complete repointing of one facade. Lasts 40+ years.
Full building (all sides)
$60K – $150K+
Multi-facade or 6+ story buildings. Often paired with FISP repair work.
Frequently asked questions
How do I know if my building needs repointing?
Look at the mortar joints. If you can scrape them out with a screwdriver, dig at them with a fingernail, or see crumbling powder when you brush them — they are failed. If the joints are visibly recessed, cracked, or missing in places, they are failed. Most buildings need repointing every 40–60 years; many older NYC buildings are overdue.
What's the difference between "pointing" and "tuckpointing"?
Technically, "tuckpointing" originally referred to a specific decorative technique of installing two contrasting mortar colors to mimic finer joints. In NYC contractor usage today, "pointing," "repointing," and "tuckpointing" are largely used interchangeably to mean joint replacement. We will quote you for whatever is actually needed, regardless of the label.
Can I just have part of the wall done?
Yes — selective or "spot" pointing is a legitimate scope when most of the wall is sound. We frequently do partial pointing as part of FISP repair work or after specific water-entry events.
Will the new mortar match the old?
If the contractor knows what they are doing, yes — closely. We mix and color-match on site, and we test on a small area first. After 6–12 months of weathering, properly matched repointing is essentially invisible from the sidewalk. Mismatched pointing, on the other hand, screams from across the street.
