Homeowners typically pay for a chimney liner replacement or installation that reflects liner material, length, and labor. The main cost drivers are liner diameter, length, material (aluminum vs. stainless steel), number of connections, and whether a professional inspection or permits are required. This guide presents clear low–average–high price ranges to help plan a budget and compare quotes.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Chimney Liner (materials) | $900 | $1,800 | $4,200 | Aluminum liners are cheaper; stainless steel offers durability for moisture and heat. |
| Labor & Installation | $600 | $1,200 | $2,400 | Includes removal of old liner and fitting the new liner; varies by complexity. |
| Length & Diameter | $200 | $600 | $1,200 | Per linear foot pricing can apply when length is uncertain. |
| Permits & Inspections | $0 | $200 | $600 | Code requirements vary by jurisdiction. |
| Delivery/Removal of Old Liner | $0 | $100 | $350 | Includes disposal fees for old material. |
| Additional Components | $50 | $250 | $800 | Elbows, seals, adaptors, and insulation may add cost. |
Assumptions: region, specs, labor hours.
Overview Of Costs
Gas furnace chimney liner projects typically range from about $1,200 to $3,000, with per-foot costs commonly around $15 to $60 depending on material and complexity. The total depends on liner length, chosen material, and whether any structural work or code compliance steps are needed. A straightforward aluminum liner for a short run can land near the lower end, while a long stainless steel run with multiple elbows and a required inspection approaches the upper end. Assumptions: region, specs, labor hours.
The following breakdown provides both total project ranges and per-unit ranges to help compare bids. Materials and labor comprise the majority of the price, with permits and disposal adding modests amounts in many markets. When estimating, consider the furnace flue condition, whether a relining is replacing a failed liner or upgrading for efficiency, and if a professional cleaning is included.
Cost Breakdown
| Category | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $900 | $1,800 | $4,200 | Aluminum $25–$60/ft; stainless steel $40–$100/ft depending on wall thickness. |
| Labor | $600 | $1,200 | $2,400 | Includes labor for installation, sealing, and testing the system. |
| Permits | $0 | $200 | $600 | Code compliance often requires inspection. |
| Delivery/Disposal | $0 | $100 | $350 | Removal of old liner and materials. |
| Accessories | $50 | $250 | $800 | Seals, brackets, insulation, and adaptors. |
| Taxes & Overhead | $0 | $60 | $180 | Varies by contractor and locale. |

What Drives Price
Material choice and length are the primary price drivers. Stainless steel liners resist corrosion and heat better in humid chimneys but cost more upfront than aluminum. Longer runs require more material and labor, and additional elbows or complicated bends raise both material and labor costs. If the chimney has multiple flues or a wide diameter transition, expect higher installation complexity. The condition of the existing chimney—whether it’s structurally sound or in need of repairs—also influences the final bill.
Other factors to consider include local building codes, the need for permits or inspections, and whether a flue cleaning or liner testing is bundled into the job. Hidden costs may include cleaning and resealing around masonry joints or minor masonry repairs.
Regional Price Differences
Prices vary by region due to labor rates and material availability. In the Northeast, higher labor rates can push totals upward, while the Midwest may offer more economical installation but tighter permit processes. The West Coast often adds costs for environmental or disposal considerations. For three typical markets, a mid-range replacement can diverge by as much as ±15% to ±25% from the national average, depending on local rules and preferred materials. Region-specific estimates help avoid sticker shock.
Labor & Installation Time
Most installations take a single day for a straightforward liner and a second day if masonry work or a chimney clean is required. Typical crew costs reflect 6–10 hours of skilled labor, with higher rates for specialized work or complex flue configurations. If lead time includes a site visit, initial assessment, and post-install testing, total hours may extend accordingly. Labor efficiency and site access directly affect final price.
Additional & Hidden Costs
Potential add-ons include a comprehensive chimney inspection, liner testing for leaks, heat shield installation, and insulation around the liner. If the old liner cannot be safely removed, extra demolition or air-sealing steps may be necessary. Some contractors quote a flat project price that excludes optional services; others itemize each element. Clarify what is included to avoid surprise fees at completion.
Real-World Pricing Examples
Below are three scenario cards to illustrate typical quotes in U.S. markets. Prices assume standard residential gas furnaces with a single flue and moderate length.
Basic Scenario: Aluminum liner, 12 ft run, 1 elbow, no permits needed, no cleaning bundled. Specs: 12 ft, 4 in diameter. Labor 6 hours. Materials $600, Labor $800, Permits $0, Accessories $50. Total $1,450.
Mid-Range Scenario: Aluminum liner, 25 ft run, 2 elbows, minor masonry touch-up, permit and inspection. Specs: 4 in diameter. Labor 8 hours. Materials $1,100, Labor $1,000, Permits $250, Accessories $150. Total $2,500.
Premium Scenario: Stainless steel liner, 40 ft run, 3 elbows, full inspection, minor masonry repairs, insulation. Specs: 4–6 in diameter; upgrades as needed. Labor 12 hours. Materials $2,500, Labor $1,800, Permits $500, Accessories $350. Total $5,150.
Assumptions: region, specs, labor hours.
