Quick Cost Reference
Crown sealing: $300–$700. Full crown rebuild: $700–$1,500. Flashing repair: $300–$1,500. Repointing / tuckpointing: $1,500–$3,500. Chimney liner installation: $2,000–$5,000.

Your actual quote depends on the chimney.
What Drives the Price
Five things move the number up or down: how big and tall the chimney is, how steep the roof is, how badly the masonry has deteriorated, what materials you choose (stainless vs. clay liner, standard vs. historic-match brick), and the time of year. Spring through fall is easier and cheaper for most masonry work; winter requires special precautions.
Why Cheap Quotes Cost More Long-Term
If you get a quote that's dramatically lower than the others, ask why. Common reasons: surface mortar smears instead of real repointing, tar-only flashing repairs, undersized liners, or skipped crown overhangs. These shortcuts last 1–3 years before failing — at which point you pay again, plus the cost of any water damage that happened in between.
Getting an Honest Estimate
A real chimney repair quote should include a written scope of work, the specific materials being used, who's pulling the permit (if needed), and a clear price. If you're getting numbers thrown at you over the phone without an inspection, that's a red flag.
