THE SHORT ANSWER
How to Estimate Chimney Masonry Repair
100 sq ft with moderate damage, repointing and 16 masonry hours at $70 totals about $5,120.
Measure exposed masonry
Price by the exposed chimney area above the roofline. Measure height by the visible face widths.
- Masonry area
- Damage level
- Repointing
- Crown
Rate the damage
Crumbling mortar is minor; cracked or displaced bricks are moderate; a leaning chimney is major and needs an engineer.
Repointing vs replacement
Repointing rakes and refills joints at a moderate per-area cost. Replacing damaged bricks adds a per-brick line.
Crown and cap protect the top
A cracked crown lets water in. Quote crown repair or replacement to finish the job.
