Chimney Repair Cost Calculator

Sweep or full rebuild? Price the right rung of the repair ladder.

Quick answer

Chimney repair averages $455 nationally in 2026, with basic repairs at $160–$750. By type: repointing costs $500–$2,500, crown repair $200–$700 (replacement up to $3,000), flashing $200–$1,800, flue liner $1,500–$7,000, partial rebuild $1,000–$5,000, and full rebuild $4,000–$15,000.

Calculator

How it works

Repair base rate × material multiplier × height multiplier

2026 bases: sweep $130–$380 through full rebuild $4,000–$15,000. Material: masonry 1.0x, metal 0.8x, prefab 0.7x. Height: 1-story 1.0x, 2-story 1.25x, 3-story 1.5x.

Match the rung to the symptom

Mortar-only damage → repointing. Spalling brick → partial rebuild. Leaks near fireplace → check flashing first (cheapest fix).

Worked example

2-story masonry, repointing:

$1,500 × 1.0 × 1.25 = $1,875

Range: $625 – $3,125.

"Chimney repair" isn't one job — it's a ladder from a $160 sweep to a $15,000 rebuild, and where you land depends on what's actually wrong. The most expensive mistake is paying for the wrong rung: repointing a chimney that needs rebuilding, or rebuilding one that needed repointing.

This calculator prices each repair type separately with material and height adjustments, so you can match the quote in your hand to the job it actually describes.

How to assess your chimney

  1. Look at the mortar: crumbling or missing joints = repointing candidate ($500–$2,500).
  2. Check the crown: cracks in the concrete cap = crown repair ($200–$700) before water gets in.
  3. Inspect flashing after rain: water near the fireplace = likely flashing ($200–$1,800), not masonry.
  4. Test the flue: a damaged liner is a fire and carbon-monoxide risk — liner work ($1,500–$7,000) is safety, not cosmetic.

Chimney repair by type (2026 US averages)

Repointing / tuckpointing$500–$2,500Failed mortar joints
Crown repair / replacement$200–$3,000Cracked concrete cap
Flashing repair$200–$1,800Roof-chimney leaks
Flue liner$1,500–$7,000Damaged flue, draft, safety
Partial rebuild$1,000–$5,000Spalling brick above roofline
Full rebuild$4,000–$15,000Structural failure

Worked example: 2-story masonry, repointing

Two-story brick chimney needing full repointing:

  1. Base: $1,500 (mid repointing).
  2. Material masonry: × 1.0.
  3. Height 2-story: × 1.25.
  4. Total: ~$1,875; range $625–$3,125.

~$1,875 for 2-story masonry repointing — scaffolding and access drive the height multiplier.

Pro tips for chimney repair

  • Get the chimney swept and inspected annually ($130–$380) — most repair needs are found this way.
  • Seal hairline crown cracks immediately ($30–$60 DIY) — water + freeze-thaw turns them into $3,000 crowns.
  • Waterproof masonry every 5–10 years ($150–$820) — breathable sealer prevents spalling.
  • If the quote says "rebuild," ask exactly how far down — roofline vs ground level is a $10,000 difference.
  • Never burn unseasoned wood — creosote from wet wood is the #1 chimney fire cause.

How to use the chimney repair cost calculator

Pick the repair type (from sweep to full rebuild), set the chimney material and stories. The calculator applies 2026 per-repair rates with material and height multipliers — masonry costs most, and two-story work adds ~25% for scaffolding and access.

How chimney repair cost is calculated

Total = repair base rate × material multiplier × height multiplier. 2026 bases: sweep $130–$380, repointing $500–$2,500, crown $200–$3,000, flashing $200–$1,800, liner $1,500–$7,000, partial rebuild $1,000–$5,000, full rebuild $4,000–$15,000. Material: masonry 1.0x, metal 0.8x, prefab 0.7x. Height: 1-story 1.0x, 2-story 1.25x, 3-story 1.5x.

Repointing vs rebuild: the decision that saves thousands

If only the mortar is failing, repointing ($500–$2,500) restores the chimney. If bricks are spalling, cracking through, or the stack leans, you need at least a partial rebuild ($1,000–$5,000). Paying for repointing on a chimney that needs rebuilding wastes the repointing money entirely.

Chimney repair cost example

Masonry chimney, 2 stories, repointing: $1,500 × 1.0 × 1.25 = ~$1,875, ranging $625–$3,125. Same chimney needing a new stainless liner: $3,500 × 1.0 × 1.25 = ~$4,375, ranging $2,500–$8,750.

The flashing blind spot

Half of all "chimney leaks" are actually flashing failures ($200–$1,800) — not chimney problems at all. If water appears near the fireplace after rain but the masonry looks sound, suspect flashing first. It\'s the cheapest fix on the whole ladder.

Frequently Asked Questions

How much does chimney repair cost in 2026?+
Chimney repair averages $455 nationally in 2026, with basic repairs ranging $160–$750. By type: repointing $500–$2,500, crown repair $200–$3,000, flashing $200–$1,800, flue liner $1,500–$7,000, partial rebuild $1,000–$5,000, and full rebuild $4,000–$15,000.
What is the most common chimney repair?+
Repointing (tuckpointing) — grinding out failed mortar and replacing it ($500–$2,500). Mortar fails long before brick does, so most "crumbling chimney" quotes are really mortar jobs. Second most common: flashing repair ($200–$1,800), the #1 source of chimney-adjacent roof leaks.
How do I know if my chimney needs repointing or rebuilding?+
Repointing suffices when damage is limited to mortar joints. You need partial rebuild when bricks themselves are spalling (flaking), cracking through, or the stack is leaning — typically $1,000–$5,000 above the roofline. A full rebuild ($4,000–$15,000) is for structural failure from the ground up.
How much does a chimney sweep cost?+
A professional chimney sweep costs $130–$380 in 2026, and an inspection runs $80–$200+. Annual sweeping is recommended for wood-burning fireplaces — creosote buildup is a fire hazard, and the sweep is when most repair needs are discovered.
Can I use my fireplace with a cracked chimney crown?+
Hairline crown cracks: seal them promptly ($30–$60 DIY sealer) and you're fine. But a badly cracked or missing crown lets water into the masonry, where freeze-thaw cycles destroy it from inside — a $200 crown repair ignored becomes a $3,000 crown replacement or worse.
Does a leaning chimney need to be rebuilt?+
A leaning chimney ($2,000–$4,000 to straighten, or $1,000–$5,000+ for partial rebuild) is a structural red flag — it can indicate foundation issues under the chimney or failed mortar throughout. Get a masonry pro and possibly a structural engineer before it becomes a collapse risk.
