Chimney Repair Cost Estimator
Price a chimney repair before you call a mason: pick the repair type, set the chimney height, and get a realistic range. Everything runs in your browser. Nothing is sent anywhere.
Chimney repairs cost $160 to $750 for basic work in 2026 (about $455 on average), but the range by repair type is wide: tuckpointing $500 to $2,500, chimney liner replacement $1,500 to $7,000, crown repair $200 to $700 (replacement $1,000 to $3,000), flashing repair $300 to $1,800, cap replacement $200 to $850, partial rebuilds $1,000 to $5,000, and full rebuilds $4,000 to $15,000. Taller chimneys and difficult access push costs up for scaffolding.

How the math worked
This is an estimate for planning only, not a quote. Chimney costs vary by region, chimney height, access, and the extent of hidden damage. A Level 2 camera inspection ($200 to $1,000) is the right diagnostic before liner or rebuild work. Never use a fireplace with a known liner or structural problem.

Water is the enemy; the repair type is just the symptom
Nearly every expensive chimney repair traces back to water. Rain enters through a cracked crown or missing cap, saturates the masonry, and freeze-thaw cycles pry it apart from the inside. Failed flashing lets roof runoff pour down the chimney's exterior. The $200 crown repair ignored for three winters becomes the $2,500 tuckpointing job, which becomes the $8,000 rebuild. Chimney economics reward early intervention more than almost any other home system.
The inspection hierarchy matters. A Level 1 inspection is a visual check, often bundled with the annual $130 to $380 cleaning, and it is enough for a chimney used normally with no changes. A Level 2 inspection adds a camera scan of the flue interior and is the standard after a chimney fire, during a real estate transaction, or when switching fuel types. Never authorize a liner replacement or rebuild on a Level 1 visual alone; the camera shows what the eye cannot, and it is the difference between a $3,000 liner and a $9,000 rebuild you did not need.
Match the repair to the failure. Tuckpointing fixes failed mortar joints, not spalling brick; if the brick faces are popping off, individual brick replacement ($20 to $30 per square foot) or partial rebuild is the honest fix. A new liner fixes a failed flue, not a leaning stack; structural movement needs masonry work first. Contractors who recommend the expensive fix for every symptom are selling, not diagnosing.
Document before you repair. Photograph everything before work begins. If the damage was sudden (storm, lightning, chimney fire), those photos are your insurance claim. If it was gradual, they are your baseline for the next inspection. Either way, a written quote with photos is what reputable chimney companies provide as standard practice.
