A new chimney liner typically costs $1,000-$5,000 installed, with many standard stainless-steel relining jobs averaging about $2,500. The final price depends on flue height and diameter, liner material, chimney condition, access, and whether the old liner must be removed.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed stainless-steel liner | $1,000 | $2,500 | $5,000 | Common 20-30 ft residential flue |
| Stainless liner per linear foot | $50 | $100 | $175 | Installed; diameter and access affect rate |
| Cast-in-place liner | $2,500 | $4,500 | $7,500 | Often includes masonry preparation |
| Clay tile liner replacement | $2,000 | $4,000 | $8,000 | May require chimney rebuilding |
New chimney liner price for a typical 20-foot flue
For a straight, accessible 20-foot flue serving a standard fireplace or furnace, a stainless-steel liner commonly totals $1,500-$3,500 installed. Small, uncomplicated jobs may start near $1,000; larger or difficult installations can exceed $5,000. Estimates generally include the liner, top termination, connection pieces, and installation.
For a straightforward residential stainless-steel installation, budgeting around $2,000-$3,000 is a reasonable starting point. A chimney inspection or cleaning may be quoted separately, and local labor rates can shift the estimate. Assumptions: 20-foot flue, standard stainless steel, normal roof access, and no major masonry repairs.
What stainless steel, labor, and removal add to the quote
Quotes can bundle materials and labor or list them separately. The table shows common components; not every job needs liner removal, scaffolding, or repairs. Ask whether the estimate includes a cap, insulation, connector, cleanup, and applicable sales tax.
| Quote component | Typical price | Pricing basis | What changes it |
|---|---|---|---|
| Stainless liner and fittings | $400-$1,500 | $20-$60 per ft for liner materials | Diameter, steel grade, and length |
| Installation labor | $600-$2,000 | $75-$150 per hour | Crew size, access, and flue condition |
| Insulation and termination cap | $150-$700 | $100-$500 per system | Required insulation and cap type |
| Old liner removal or disposal | $200-$1,500 | Per project | Debris, tile condition, and access |
| Inspection and cleaning | $150-$500 | Per visit | Inspection level and buildup |
Labor and access often make as much difference as the liner material itself. A basic crew may finish in 4-8 hours, while removal or repairs can extend work to one or two days.
How flue diameter and chimney height change the estimate
Height directly affects liner length and installation time. A 15-foot run uses less material than a 30-foot run, while a roof that is steep, high, or difficult to reach can raise labor and setup charges. Many installed quotes work out to roughly $50-$175 per linear foot, but minimum service charges mean short liners do not always cost proportionally less.
Diameter must match the connected appliance and its venting requirements. A 5- or 6-inch liner for some heating appliances may cost less than an 8- or 10-inch fireplace liner; larger sizes use more material and can be harder to maneuver. Changes in diameter should be based on a qualified assessment, not price alone.
Both extra height and a larger flue can push a quote above the standard range. Offset flues, tight clearances, and damaged tile can add labor even when the chimney is not especially tall.
How long does a chimney relining job take?
A simple stainless-steel liner installation often takes one workday, with roughly 4-8 hours on site for a two-person crew. A job requiring old tile removal, insulation, roof staging, or repairs may take 1-2 days. The quoted labor price should identify whether inspection, setup, cleanup, and appliance reconnection are included.
Confirm the work duration and included tasks before comparing labor totals. A low bid may exclude cleaning, removal, or a required connection component that appears as an add-on later.
Which liner type costs less over time?
Flexible or rigid stainless-steel liners are common for relining an existing masonry chimney and typically cost $1,000-$5,000 installed. Cast-in-place systems, which form a liner inside the flue, often run $2,500-$7,500. Replacing damaged clay tiles can cost $2,000-$8,000 or more because the work may involve opening and rebuilding masonry.
The lowest initial price is not always the best match for the fuel and appliance. Liner material and size must be compatible with wood, gas, oil, or another appliance type. A professional should specify the suitable system and any warranty terms in writing.
What extra charges appear on older masonry chimneys?
Cracked tile, heavy creosote, a damaged crown, or a blocked flue may require work before lining. Cleaning commonly costs $150-$350; more involved inspection or diagnostics can bring the visit to $500. Masonry repairs may add $300-$2,000, while difficult removal of a deteriorated tile liner can add several hundred dollars or more.
Request an itemized allowance for concealed damage rather than assuming the base quote covers it. Local permit requirements vary, and permit or inspection charges may add about $50-$300 when required. Confirm who obtains permits and pays fees.
Where do chimney liner prices run higher?
Prices tend to be higher in major coastal metros and high-cost urban areas than in many rural or lower-cost markets. A rough planning adjustment is 10%-25% above a national-style estimate in expensive cities, while some rural markets may run 5%-15% below it. Travel distance, contractor availability, roof access, and local code requirements can outweigh regional averages.
Compare local, itemized bids for the same liner length, diameter, material, and included work. A regional percentage is only a budgeting aid, not a substitute for a site-specific inspection.
Can prep and quote comparisons lower relining price?
Ask for two or three written estimates that specify liner material and grade, diameter, measured length, insulation, cap, removal, cleanup, and warranty. Schedule routine work outside the busiest periods when possible, and provide clear access to the fireplace and work area. Combining inspection or cleaning with the installation may reduce repeat trip charges, but only if the tasks are priced transparently.
Keep the scope consistent before choosing the lowest total. Avoid paying for an upgrade unless the appliance, flue condition, or local requirements call for it; do not trim necessary sizing, safety, or code work to reduce the bid.
