Chimney costs
How much does a chimney liner cost?
$2,500–$6,000 for a full stainless reline. It is the most expensive routine job in this trade, and not because of markup.
$2,500 to $6,000 stainless, more for cast-in-place. It is a full-height component, not a patch.
Chimney liner cost is the biggest routine number on this site, and the reason is physical rather than commercial: you are buying a component that runs the entire height of the chimney, plus one to two days of skilled work to get it there. Stainless is the usual answer at $2,500 to $6,000 depending on height and diameter. Cast-in-place costs more and takes longer, and it earns that on an irregular flue or a stack whose masonry needs the structural help. Anyone quoting either without having put a camera down first is quoting a length they have not measured.
What you are buying
The full height, not a patch
The liner runs from the firebox to the cap. That is why relining is priced by the foot and why the flue height is the first question.

Chimney liner cost by type
Every figure here is a band, because a single number for work nobody has looked at yet would be a guess dressed up as a quote.
| The job | Typical range | What moves it |
|---|---|---|
| Stainless liner, insulated, full height | $2,500–$6,000 | Flue height and diameter |
| Stainless for a stove or insert | $1,800–$4,000 | Smaller diameter, shorter run |
| Cast-in-place lining | $5,000–$12,000 | Adds structural strength to the stack |
| Partial clay tile repair | $1,000–$3,000 | Rarely available — usually the rest is going too |
| Insulating an existing liner | $800–$2,000 | Exterior-wall chimneys need it most |
| Breaking out old clay tile first | +$1,000–$3,000 | Whether there is room without it |
US-wide bands for planning, not a quote. Regional labour rates move all of these, and the only number that means anything is a written estimate for your chimney.
What actually decides the number
Flue height
You are buying a component the full height of the chimney. A single-storey flue and a three-storey one are the same job with very different material lengths.
The diameter the appliance needs
Set by the stove or insert manual, not by the old flue. Getting this wrong makes a liner that draws badly and builds creosote fast, which is worse than the flue you replaced.
Whether the chimney offsets
A straight run drops in. A flue that jogs around a floor above takes far longer and sometimes needs a rigid liner assembled in sections.
Whether old clay tile has to come out
Sometimes there is room for the new liner alongside; often the old tile has to be broken out first, which is dusty, slow work and a meaningful part of the bill.
Stainless or cast-in-place
Different jobs at different prices. Cast-in-place bonds to the surrounding masonry and adds strength, which is why it wins on a deteriorating stack despite costing more.
Should be included
- A camera scan before any figure is quoted
- The liner sized to the appliance, not to the old flue
- Insulation wrap or pour where the flue needs it
- A new top plate, storm collar and cap
- The manufacturer's warranty paperwork, handed over on the day
Priced separately
- Breaking out old clay tile, where there is no room alongside
- Masonry repairs the scan finds on the way
- A crown recast, if the top has to be opened up
- Sweeping, if the flue needs it before the scan
- Making good interior finishes, on a cast-in-place job
Quotes to walk away from
- A reline quoted from a photograph or a phone description. Nobody can price a length they have not measured.
- A liner sized to the old flue rather than to the appliance manual.
- No insulation mentioned on an exterior-wall chimney. That is where cold flues and fast creosote come from.
- No warranty paperwork offered. A stainless liner should carry a manufacturer's warranty and conditions.
- Pressure to decide today on a job of this size. Nothing about a reline is more urgent tomorrow than it is next week.
The VIO Standard
- A written estimate first
- License and insurance checked

Common questions
Why does a chimney liner cost so much?
Because it is a full-height component rather than a repair to part of one. A three-storey flue needs thirty-odd feet of insulated stainless, a top plate, a collar, a cap, and a day or two of skilled work to get it down a shaft that may jog around a floor on the way. That is not markup, it is what the job contains. The place to be sceptical is the quote given without a scan, not the size of an honest number.
Is a stainless or cast-in-place chimney liner better value?
Stainless for most jobs — faster, cheaper, warranted, and sized precisely to the appliance. Cast-in-place earns its premium in two situations: a flue too irregular for a tube, and a stack whose masonry is deteriorating, because the poured liner bonds to the surrounding brick and adds strength a steel tube cannot. On a failing chimney it is sometimes the only option that makes sense.
Can I reline just part of a chimney?
Occasionally, and less often than people hope. If a single tile is cracked in an otherwise sound flue, sealing or replacing that section is possible. In practice one cracked tile is usually a statement about the condition of the rest — they are the same age, they have taken the same heat cycles, and a partial repair on a flue that is generally failing means paying for access twice. The scan is what settles it.
Does a chimney liner come with a warranty?
A stainless one should, and it is worth reading which. Manufacturers typically offer a lifetime warranty to the original homeowner, conditional on correct installation and on the flue being maintained — usually meaning annual sweeping with records kept. Cast-in-place systems carry their own on similar terms. Ask for the documentation on the day rather than a year later when you need it.
Is relining cheaper during a rebuild?
Considerably, and it is the strongest argument for doing both together. During a rebuild the stack is already open and the access is already paid for, so adding a liner costs a fraction of what the same liner costs as a standalone job later. If a rebuild is on the table and the liner is marginal, do them in one go.

The only number that counts is the one for your chimney.
Ranges are a starting point. A written estimate after someone has looked at it is the real answer, it costs nothing to ask for, and you are not committed to accepting it.
