A stainless chimney liner kit is priced by the length and diameter your chimney needs, so the total depends on your flue rather than a single sticker price. Doing the reline yourself saves the most; hiring a professional costs more but preserves the full warranty. The fastest way to a real number is to have us price your exact kit.
| What drives the price | Why it changes the cost |
|---|---|
| Diameter (5, 6 or 8 inch) | A wider flue uses more stainless material |
| Length (your chimney height) | Liner is priced per foot, so a taller chimney costs more |
| Insulation | An insulation wrap adds material and effort, and is often needed on an exposed chimney |
| Connection parts | Top plate, rain cap, tee or appliance connector for your setup |
| DIY vs professional | DIY saves the labor cost; a professional reline preserves the warranty |
DIY Chimney Liner Kit Cost
A complete DIY chimney liner kit -- flexible stainless steel liner, top plate, rain cap, and bottom connector -- typically costs between $300 and $800 for standard diameters (5" or 6") and lengths up to 20 feet. Larger diameters (7" and 8") and longer runs push the price toward $800 to $1,200.
| Kit Configuration | Typical Cost | What's Included |
|---|---|---|
| 5" or 6" x 15-20 ft, basic | $300 - $650 | Liner, top plate, rain cap, appliance connector |
| 5" or 6" x 20-30 ft, basic | $500 - $800 | Liner, top plate, rain cap, appliance connector |
| With tee connector (side entry) | Add $50 - $120 | Tee + tee cap replaces the appliance connector |
| With insulation | Add $100 - $250 | Ceramic blanket wrap or vermiculite pour |
| With pulling cone | Add $20 - $40 | Makes feeding the liner down the chimney easier |
These prices are for stainless steel kits (316Ti or 316L), which are the standard for wood, gas, oil, pellet, and coal burning appliances. Aluminum kits exist for less ($100 to $300), but they only work with gas appliances and have a much shorter lifespan.
Professional Chimney Liner Installation Cost
Professional chimney relining costs $1,500 to $5,000 on average. Complex jobs -- tall chimneys, difficult access, cast-in-place liners, or chimneys that need repair before lining -- can reach $7,000 or more.
| Service | Cost Range |
|---|---|
| Stainless steel flexible liner (installed) | $1,500 - $3,800 |
| Clay tile liner (installed) | $2,000 - $3,500 |
| Cast-in-place liner (installed) | $2,000 - $7,000 |
| Chimney inspection (Level 2, with camera) | $150 - $500 |
| Old liner removal (if needed) | $500 - $1,500 |
Labor typically accounts for 40% to 60% of the professional price. The materials are the same ones available in DIY kits -- the difference is the labor, the inspection, and the warranty on the workmanship.
DIY Kit vs Professional: The Real Difference
For a typical 6" x 20-foot chimney with a straight run and no major damage, the cost comparison looks like this:
| DIY Kit | Professional | |
|---|---|---|
| Materials | $500 - $700 | $500 - $700 (same) |
| Labor | Your time (4-8 hours) | $800 - $2,000 |
| Inspection | Optional ($150 - $500) | Usually included |
| Product warranty | Lifetime (on materials) | Lifetime (materials + labor) |
| Total | $500 - $1,200 | $1,500 - $3,800 |
The savings from a DIY kit are typically $1,000 to $3,000. That makes chimney relining one of the higher-value DIY projects for homeowners who are comfortable working on a roof and following instructions carefully.
When Does DIY Make Sense?
A DIY chimney liner kit is a good fit when:
- Your chimney has a straight, unobstructed run from top to bottom
- The masonry is in sound condition (no crumbling mortar, no structural damage)
- You are relining a chimney that already has a flue opening at the top and a connection point at the bottom
- You are comfortable working on a roof safely
Hire a professional when:
- Your chimney has offsets, bends, or damage that needs repair first
- You need the old clay tile liner removed (this requires specialized equipment)
- Local building codes require a professional installation or a permit
- You are connecting to a fireplace insert (these often have tighter clearances)
If you are unsure, a chimney inspection ($150 to $500) before you buy anything will tell you whether your chimney is a candidate for a DIY kit or needs professional work.

What Drives the Cost of a Chimney Liner Kit?
Diameter
Liner diameter is determined by your stove or appliance. Most wood stoves use a 6-inch liner. Pellet stoves typically use 5-inch. Larger open fireplaces and some fireplace inserts may need 7-inch or 8-inch. The larger the diameter, the higher the material cost -- a 6-inch liner costs roughly 20% to 30% more than a 5-inch of the same length.
Length
Measure from the top of your chimney to the stove connection point. Most residential chimneys are 15 to 25 feet. Add a few extra feet for the top plate connection and any bends. Kits are typically available in standard lengths (15, 20, 25, 30 feet), with custom lengths available on request.
Material Grade
Stainless steel chimney liners come in several grades:
| Grade | Suitable For | Typical Cost Impact |
|---|---|---|
| 304 stainless steel | Gas, oil, wood (with insulation per UL 1777) | Base price |
| 316L stainless steel | All fuels including wood, coal, pellet | 10% - 15% more than 304 |
| 316Ti stainless steel | All fuels including wood, coal, pellet | 15% - 25% more than 304 |
| Aluminum | Gas only (not for wood or oil) | 50% - 70% less than stainless |
For wood burning applications, 316L and 316Ti are the recommended grades. Both carry lifetime warranties from reputable manufacturers. Aluminum is only suitable for gas appliances and has a shorter lifespan (5 to 15 years). Grade is only half the decision; our guide to the three types of chimney liner covers the shape of the liner itself.
Insulation
Insulation is not always required, but it improves performance and is sometimes mandatory by code. Wood-burning appliances in particular benefit from an insulated liner because it keeps flue gases hotter, which reduces creosote buildup and improves draft.
Insulation adds $100 to $250 to a kit. The two common types are ceramic blanket wrap (wrapped around the liner before installation) and vermiculite pour (poured into the gap between the liner and the chimney wall after installation). For more detail, see our guide on insulated vs non-insulated chimney liners.
Connection Type
Your kit needs a connection at the bottom where the liner meets the stove or appliance. There are two main types:
- Appliance connector (vertical): used when the stove pipe enters the chimney straight up from the top of the stove. Simpler and less expensive.
- Tee connector (horizontal): used when the stove pipe enters the chimney from the side, through a thimble in the wall. The tee adds $50 to $120 to the kit cost.

What Is Included in a Chimney Liner Kit?
A complete stainless steel chimney liner kit should include everything you need to reline from top to bottom:
| Component | Function |
|---|---|
| Flexible chimney liner | The main tube that runs the full length of the chimney |
| Top plate | Seals the top of the chimney around the liner |
| Rain cap | Keeps rain, animals, and debris out of the flue |
| Appliance connector or tee | Connects the liner to the stove pipe at the bottom |
Some kits also include a storm collar (seals the gap between the top plate and the liner against weather) and clamps. Insulation and pulling cones are usually optional add-ons.
Watch out for "kits" that are actually just the liner without components. If a price looks too low, check whether the top plate, cap, and connector are included or sold separately. Buying components individually almost always costs more than a pre-configured kit.
How to Save Money on Chimney Relining
- Use a configurator. A kit configurator lets you select exactly the diameter, length, connection type, and add-ons you need -- no over-ordering, no missing parts. Configure a chimney liner kit here.
- Get a free flue design check. Choosing the wrong diameter or length wastes money on returns and re-orders. A free flue design service confirms your measurements before you order.
- Skip insulation only if your situation allows it. Gas appliances in a sound masonry chimney often do not require insulation. Wood-burning appliances almost always benefit from it. Our guide on chimney liner insulation covers when it is required and when it is optional.
- Buy the kit, not the parts. A complete kit with top plate, cap, and connector is almost always cheaper than buying each component separately.
- Do not cheap out on material grade. Aluminum liners cost less upfront but only last 5 to 15 years and are limited to gas. A stainless steel liner with a lifetime warranty is the better long-term value.
Cost by Chimney Height
Most of the cost of a chimney liner kit is in the liner itself, which is priced per foot. Here is a rough guide to total kit cost by chimney height for a 6-inch stainless steel kit with appliance connector:
| Chimney Height | Estimated Kit Cost (6", no insulation) |
|---|---|
| 15 feet | $400 - $550 |
| 20 feet | $500 - $700 |
| 25 feet | $600 - $850 |
| 30 feet | $700 - $1,000 |
Add $100 to $250 for insulation, $50 to $120 if you need a tee connector instead of an appliance connector, and $20 to $40 for a pulling cone.

Frequently Asked Questions
How long does a chimney liner last?
A stainless steel chimney liner (316L or 316Ti) typically lasts 15 to 20 years or more with proper maintenance. Most come with a lifetime warranty. Aluminum liners last 5 to 15 years. Clay tile liners can last 50 years but are prone to cracking under high heat.
Do I need a chimney liner?
If you burn wood, pellets, coal, or oil, building codes in most US states require a chimney liner. Even for gas appliances, a liner improves safety and efficiency. If your existing liner is cracked, deteriorated, or missing, relining is a safety necessity, not an upgrade. See our detailed guide on why a chimney liner is required.
Can I install a chimney liner myself?
Yes, if your chimney has a straight run, is in sound structural condition, and you are comfortable working on a roof. A flexible stainless steel liner kit is designed for homeowner installation -- it does not require specialized tools beyond a screwdriver, a drill, and basic hand tools. For step-by-step guidance, see our chimney liner installation instructions.
How do I know what size liner I need?
Match the liner diameter to the flue collar on your stove or appliance. Most wood stoves use 6-inch, pellet stoves use 5-inch, and larger open fireplaces may need 7-inch or 8-inch. Never install a liner smaller than the appliance requires. For length, measure from the top of your chimney to the connection point and add a few feet. If you are unsure, our team offers a free flue design service to help you get the right size.
Do I need to insulate my chimney liner?
It depends on your fuel type and chimney construction. Wood-burning appliances benefit significantly from insulation because it keeps flue gases hotter, reduces creosote, and improves draft. Gas appliances in a sound masonry chimney may not require it. Check your local codes and see our comparison of insulated vs non-insulated liners.
