Tuckpointing Cost Per Square Foot
Tuckpointing (repointing) costs $5 to $20 per square foot in 2026 for walls up to 8 feet high, and $8 to $30 per square foot above that or where scaffolding is needed. A typical chimney runs $500 to $2,500 total. It fixes failed mortar joints only; spalling or crumbling brick needs brick replacement ($20 to $30 per square foot) or partial rebuild instead.
Tuckpointing is the most quoted chimney repair and the most misunderstood: it fixes mortar, not brick. This guide prices it per square foot, explains when it is the right fix, and covers the mortar-matching details that separate good work from patch jobs.
Cost per square foot in 2026
Masons price tuckpointing by the square foot of wall area, not by the linear foot of joint. $5 to $20 per square foot for walls up to 8 feet high with easy access. $8 to $30 per square foot above 8 feet, on steep roofs, or where scaffolding is required. Small projects may be priced hourly at $50 to $125 per hour with a minimum charge. A typical two-story chimney's above-roof portion runs $1,200 to $2,800 for full tuckpointing; spot tuckpointing of the worst joints runs $500 to $900 but only makes sense when under 20 percent of joints have failed.
What tuckpointing actually is
The mason grinds or rakes out deteriorated mortar to a uniform depth (usually 3/4 inch), cleans the joints, packs in fresh mortar, and tools it to match the original joint profile. It is labor-intensive, skilled work: the grinding is slow, the mortar mixing must match, and the finishing determines whether the repair disappears or announces itself. Good tuckpointing is nearly invisible; bad tuckpointing looks like gray caulk smeared on brick.
When tuckpointing is the right fix
Tuckpoint when the mortar is receding, crumbling, or sandy, but the brick units are sound. The key test: drag a key across a mortar joint; if it leaves a groove, the mortar has failed. Tuckpointing is effective only when damage is limited to the joints. It is the right call for the common case: a 30-year-old chimney with weathered mortar and solid brick.
When it is the wrong fix
Spalling brick (faces popping off, exposing soft interior clay) means the brick itself is failing; tuckpointing over it is cosmetic. Individual brick replacement runs $20 to $30 per square foot. Structural movement (leaning, stair-step cracks widening) needs a mason's structural assessment, not new mortar. Water entry through the crown or flashing will destroy new mortar as fast as old; fix the water source first or the tuckpointing fails within a few seasons. A contractor who recommends tuckpointing without checking the brick and the water path is selling the easy job.
Mortar matching matters
Old chimneys often used lime-based mortar; modern Portland cement mortar is harder than old brick and can cause the brick faces to spall as the assembly moves. A good mason matches mortar type to the building's age: softer lime mortars for pre-1930s masonry, modern mixes for newer work. Ask what mortar they will use and why; "whatever is on the truck" is the wrong answer for a historic chimney. Color matching matters too for curb appeal on the street-facing elevation.
After the work: curing and maintenance
Fresh mortar needs time to cure: keep it damp in hot weather for several days (a light misting, not a soaking) and protect it from freezing for at least 72 hours, which is why masons avoid tuckpointing in deep winter. Do not paint fresh mortar for at least 30 days. Going forward, the maintenance that protects the investment is the same water management that should have preceded it: a sound crown with an overhang, a fitted cap, intact flashing, and gutters that do not dump onto the masonry. Tuckpointing without water management is a recurring expense; tuckpointing with it is a 30-year fix.
The bottom line
Budget $5 to $20 per square foot ($500 to $2,500 for a typical chimney) for tuckpointing sound brick with failed mortar. Confirm the brick is sound, fix water entry first, and hire a mason who talks about mortar type unprompted; that conversation is the quality signal.
