Chimney Repair Cost Calculator

It depends heavily on the work: flashing reseal $150–$500, crown repair $300–$2,000, tuckpointing $500–$2,500, liner replacement $600–$5,000, partial rebuild above the roofline $1,000–$4,000, and a full rebuild $4,000–$12,000 or more. Tall or steep-roof chimneys add roughly 35% for scaffolding and safety setup.

Tuckpointing (repointing) is grinding out eroded mortar joints and packing in fresh mortar. You need it when joints are recessed, crumbling, or letting water in - but if the brick faces themselves are spalling or flaking, those bricks must be replaced because new mortar alone will not hold.

The crown is the concrete or mortar slab at the top that sheds water away from the flue and masonry. A cracked crown or missing cap is the single most common cause of expensive chimney decay, since water intrusion drives spalling, liner damage, and eventual rebuilds.

A Level 1 inspection every year, costing about $100–$250, is recommended for any chimney in regular use. Annual inspections catch crown cracks, liner cracks, and mortar erosion early, turning what would become a costly rebuild into a minor repair.
