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.

01

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
02

Rate the damage

Crumbling mortar is minor; cracked or displaced bricks are moderate; a leaning chimney is major and needs an engineer.

03

Repointing vs replacement

Repointing rakes and refills joints at a moderate per-area cost. Replacing damaged bricks adds a per-brick line.

04

Crown and cap protect the top

A cracked crown lets water in. Quote crown repair or replacement to finish the job.
