What affects the cost?
- Liner material chosen (aluminum and stainless steel run cheapest per linear foot; cast-in-place and ceramic/thermocrete cost the most)
- Single-wall vs. double-wall construction, and rigid vs. flexible liner (double-wall and flexible cost more per foot, Fixr)
- Chimney height and number of flues that need lining
- Roof pitch and accessibility, which drive labor time
- Whether the old liner or clay tiles need to be removed first ($250-$800 for steel, $500-$2,500 for clay, HomeGuide)
- Adding insulation around the new liner ($8-$15 per linear foot, HomeGuide; $300-$800 total, Fixr)
- Chimney inspection and cleaning before installation ($125-$450, Bob Vila, Angi, HomeGuide)
- Local permit fees ($50-$200, Bob Vila; $100-$150+, HomeGuide)
- Local labor rates, generally $400-$1,500 for the installation portion (Fixr, Bob Vila, Angi)
Why does a chimney liner cost so much?
The price mainly comes down to liner material and chimney size. A full installation typically runs $625 to $7,000, averaging around $2,500 nationally (Fixr, Bob Vila, Angi). Material choice explains most of the spread: aluminum liners install for about $625 to $2,250, stainless steel (the most common relining option) runs $900 to $3,800, clay/terracotta tile lands at $2,000 to $3,500, and cast-in-place or ceramic/thermocrete liners can reach $2,000 to $7,000 (HomeGuide). Per linear foot, material alone ranges from about $5 to $90 for aluminum and stainless steel (Fixr, HomeGuide) up to $25 to $250 for cast-in-place and ceramic (Fixr). Labor for the installation itself typically adds $400 to $1,500 (Fixr, Bob Vila, Angi). Taller chimneys and multi-flue setups need more liner length, which is why the total project cost can stretch several thousand dollars beyond the national average.
What affects the cost?
A few factors explain most of the spread between a $625 job and a $7,000 one:
- Liner material. Aluminum and stainless steel cost the least per foot; cast-in-place and ceramic/thermocrete cost the most (Fixr, HomeGuide).
- Single-wall vs. double-wall, rigid vs. flexible. Double-wall and flexible stainless steel liners run more per foot than single-wall or rigid options (Fixr).
- Chimney height and number of flues. More linear feet of liner and more flues to service both add directly to material and labor cost.
- Roof pitch and accessibility. Steeper roofs and harder-to-reach chimneys slow installers down and add labor cost.
- Old liner or tile removal. Pulling out an old steel liner adds $250 to $800; removing old clay tiles adds $500 to $2,500 (HomeGuide).
- Insulation. Wrapping the new liner in insulation typically adds $8 to $15 per linear foot, or $300 to $800 for a standard job (HomeGuide, Fixr).
- Inspection, cleaning, and permits. Pre-installation inspection and sweeping usually runs $125 to $450, and permits add $50 to $200+ (Bob Vila, Angi, HomeGuide).
- Region. Local labor rates vary, which is part of why national estimates differ from source to source.
How to lower your chimney liner cost
- Choose stainless steel over cast-in-place or ceramic if your chimney’s condition allows it. Stainless steel liners install for a few thousand dollars less than cast-in-place on a typical job (HomeGuide).
- Skip insulation only if your climate and code allow it, since insulation is usually optional and adds $300 to $800 to the total (Fixr).
- Get an inspection first rather than assuming you need a full replacement. Sometimes cleaning or a partial repair, closer to the $125-$450 inspection/cleaning range, is enough (Bob Vila, Angi, HomeGuide).
- Ask what removal work is included. Old-liner or old-tile removal is often quoted separately and can add hundreds to thousands of dollars if not scoped up front (HomeGuide).
- Bundle the liner with other chimney work, like a cap or crown repair, if you’re already having a mason on-site, since a single visit usually costs less than two separate service calls.
Prices vary by region, chimney height, and liner material, so treat the figures above as a planning budget. Get two or three local quotes, and confirm what removal and insulation work each bid includes, before committing to a final number.

Frequently asked questions
How much does a chimney liner cost on average?+
The national average is about $2,500, with most homeowners paying somewhere between $625 and $7,000 depending on chimney size and liner material (Fixr, Bob Vila, Angi).
What's the cheapest type of chimney liner?+
Aluminum liners are generally the least expensive, installing for about $625 to $2,250 total, or roughly $5 to $30 per linear foot for material (HomeGuide, Fixr).
How much does a stainless steel chimney liner cost?+
Stainless steel, the most commonly installed relining material, typically runs $900 to $3,800 installed, or about $20 to $90 per linear foot depending on single-wall vs. double-wall construction (HomeGuide, Fixr).
Why is cast-in-place lining so much more expensive?+
Cast-in-place liners can cost $2,000 to $7,000 installed, or $40 to $120 per linear foot, because the process pours a cementitious material in place to form the flue rather than inserting a pre-made pipe, which takes more labor and material (HomeGuide).
Does the liner cost include removing the old liner?+
Usually not. Removing an old steel liner typically adds $250 to $800, and removing old clay tiles can add $500 to $2,500 on top of the new liner cost (HomeGuide).
Are inspection and permits included in the price?+
No, these are typically separate line items. Chimney inspection and cleaning usually runs $125 to $450, and permits add roughly $50 to $200 (Bob Vila, Angi, HomeGuide).

National average ($2,500) and the wide $625-$7,000 range are corroborated by three independently published sources: Fixr, Bob Vila, and Angi, which all cite the same national average and low/high figures. HomeGuide reports a similar but slightly tighter overall range of $1,000-$7,000, with relining/replacement specifically averaging $1,200-$4,600. The by_type breakdown uses HomeGuide's installed (material + labor) totals per material, since Fixr and Angi report material-only per-square-foot or per-linear-foot pricing instead, which isn't directly comparable to a whole-project figure. Per-linear-foot material pricing (not used in by_type to avoid mixing units) ranges roughly $5-$90 for aluminum and stainless steel (Fixr, HomeGuide) up to $25-$250 for cast-in-place and ceramic (Fixr). The installation labor figure ($400-$1,500) combines Fixr's $500-$1,500 with Bob Vila's and Angi's $400-$1,250; HomeGuide's own labor figure ($500-$3,000 for steel, $800-$3,000 for cast-in-place) is notably higher and is not folded into that combined figure. The $125-$450 inspection/cleaning figure is likewise a synthesized range combining Bob Vila's $125-$250, Angi's roughly $255-$450 sweep/inspection figures, and HomeGuide's $150-$250, rather than a single source's stated range. Figures generally cover the liner and standard installation labor; inspection, cleaning, permits, insulation, old-liner removal, and any masonry repair (crown, chimney rebuild) are commonly quoted as separate add-ons.
