As such, it’s to your benefit to repair or replace the crown as soon as there’s a problem.

Cracked Chimney Repair Cost

While fixing small cracks may cost less than $500, deeper cracks or those that affect a large area could reach up to $1,500.

Chimney Flashing Repair Costs

Repairing chimney flashing typically costs between $200 and $500, depending on the size of the chimney and the extend of damage. For larger chimneys made of stone or brick that require flank flashing and its more extensive installation process, you could pay up to $2,000 for a repair job.

If found early enough, simple brick mortar repair can resolve the issue. If left untreated, they can lead to structural damage, increased risk of fire, and can cost upwards of around $3,000 to repair.

Average Cost to Tuckpoint a Chimney

While repointing removes and repairs the mortar, tuckpointing is the process of filling in mortar and making it aesthetically appealing. This involves blending in the mortar to match with the bricks. While repointing and tuckpointing are technically different, they’re often lumped into the same service. Talk to a fireplace contractor near you for an estimate on repointing or tuckpointing your chimney.

Cost to Re-Mortar Chimney

Grout and mortar cost about $2 to $3 per square foot, plus at least $40 to $50 per hour in labor. The exact price depends on the size of your chimney. Even if the mortar of your chimney is crumbling, you might not need to buy new bricks. Re-mortaring could save you money by reusing bricks.
