If you just want the number: most chimney repointing jobs in the Lehigh Valley run $500 to $2,500. Small, easy-to-reach repairs on a single-story chimney land at the low end. Full repointing on a tall, steep-roof chimney, or one where the damage has spread past the first few rows of mortar, can run $2,500 to $5,000 or more.
That range is wide because repointing isn't priced off a single formula — it depends on how much of the joint is actually gone, how hard the chimney is to reach, and whether the brick or stone needs a mortar mix matched to a house that's a lot older than the contractor quoting it.
What "repointing" means (and how it differs from tuckpointing)
Repointing is grinding out the failed mortar between bricks or stones to a consistent depth, then packing in fresh mortar so the joint is watertight and structural again. Tuckpointing is a cosmetic variant — a thin decorative line is added on top of the new mortar to make the joints look perfectly even. Most Lehigh Valley homes just need repointing; tuckpointing is mainly for historic or show-front brickwork where the look matters as much as the seal. See our full tuckpointing vs. repointing comparison for the details.
What actually drives the price
Height and accessibility
A single-story chimney a mason can reach from a ladder costs less to repoint than a two-story chimney on a steep roof, where staging or a lift adds labor before any mortar work starts.
How much of the joint has failed
Spot repointing on the top few rows — usually the first to go, since they take the most weather — is the cheapest version of this job. If deterioration has worked its way down the stack, or previous patch jobs were done with the wrong mortar, the repair area (and the price) grows fast.
Brick vs. stone
Stone chimneys generally cost more to repoint than brick, since the joints are less uniform and take more time to pack correctly.
Matching mortar on older Lehigh Valley homes
A lot of housing stock in Allentown, Bethlehem and Easton predates modern construction and was built with softer, lime-based mortar. Repointing it with a hard, modern Portland-cement mix is a common mistake that traps moisture and cracks the surrounding brick instead of the joint. Matching the original mortar's hardness costs a little more up front and is the difference between a repair that lasts and one that creates new problems in a year or two.
Why Pennsylvania winters make this urgent, not optional
The Lehigh Valley runs through several months of freeze-thaw cycles every year — water gets into a cracked joint, freezes, expands, and widens the crack. Repeat that daily from late fall through early spring and a small gap becomes a bigger repair by the time warm weather rolls around.
Signs you're already past the point of waiting: mortar you can scrape out with a fingernail, small chunks of mortar collecting on the roof or in the gutter, a white chalky residue (efflorescence) on the brick face, or daylight visible through a joint from inside an unfinished attic. See our full signs your chimney needs repointing guide for the complete list.
Repointing vs. other chimney repairs
Repointing is often bundled with, or sometimes mistaken for, other chimney work. Roughly what each runs:
- Crown repair or replacement — sealing hairline cracks in the concrete cap runs a few hundred dollars; a full crown replacement is more, since it's the main barrier keeping water out of the chimney entirely.
- Cap replacement — the metal cover that keeps rain and animals out of the flue is a comparatively small line item, usually bundled in with a repointing job if it's due.
- Full rebuild — if deterioration has gone past the mortar and into the brick or block itself, repointing won't hold and rebuilding a section (or the full stack) is the honest answer, even though it costs more than repointing would.
Does homeowners insurance cover it?
Usually not, and it's worth knowing that before you call your carrier. Insurance typically covers sudden, specific damage — a lightning strike, a storm that knocks bricks loose. Mortar wearing down from years of freeze-thaw cycles is treated as ordinary maintenance, which policies generally exclude. Budgeting for repointing as routine upkeep, rather than expecting a claim to cover it, is the more realistic plan.
What a proper repointing job should include
A repair that's priced fairly and built to last should include:
- An actual inspection before a number gets quoted — not a price given from a photo or a drive-by.
- Mortar ground out to a real depth (roughly 3/4"), not just skimmed over the surface.
- A mortar mix chosen to match your chimney's age and material, not a one-size-fits-all bag from the truck.
- A fixed price in writing before work starts, not a vague "per row" estimate that can move once the crew is on the roof.
Choosing a contractor in the Lehigh Valley
Before hiring, it's worth asking directly: Are you licensed and insured in Pennsylvania? Will the price be fixed and in writing? Who is actually doing the work on my roof? Have you repointed homes from this era before, and what mortar mix will you use? A contractor who answers those without hesitation is usually the one who won't leave you with a bigger problem next winter.
Key takeaways
- Most Lehigh Valley repointing jobs run $500–$2,500; larger or harder-to-reach chimneys run higher.
- Matching mortar hardness to an older home's original mix matters more than the brand on the bag.
- Freeze-thaw cycles turn small cracks into bigger repairs — waiting rarely saves money.
- Insurance usually won't cover it; treat repointing as scheduled maintenance.
- Get a fixed price in writing after an actual inspection, not a phone estimate.
FAQ
How long does chimney repointing take?
Most single-chimney jobs take one to two days, depending on how much of the joint needs to be redone and how the mortar needs to cure between passes.
Can I repoint just part of the chimney?
Yes — spot repointing the worst rows (usually the top of the stack) is common and often all that's needed if the rest of the mortar is still sound.
Will repointing fix a leaking chimney?
It fixes leaks caused by failed mortar joints. If water is coming in around the crown, flashing, or cap instead, those need to be addressed separately — a real inspection will tell you which it is.
How often does a chimney need repointing?
There's no fixed schedule — it depends on the original mortar, chimney exposure, and how many freeze-thaw seasons it's been through. Many Lehigh Valley chimneys go 20+ years before needing it; older or south-facing ones can need attention sooner.
