Chimney liner installation in Maine typically costs $2,000 to $4,500, and most jobs are finished in one to two days. The right liner depends on what you burn, the size of your appliance, and the condition of your chimney. This guide covers liner types, how liners are sized, what drives the price, and what to expect on installation day, from a family-owned chimney company that has been relining chimneys in Sanford, Portland, and across southern Maine for more than 40 years.

Why Every Maine Home Needs a Chimney Liner

A chimney liner is the protective barrier inside your chimney. It keeps heat, combustion gases, and creosote away from the brick, mortar, and nearby framing, and it gives smoke a properly sized path out of the house. Older clay tile liners crack and crumble over time, and some older Maine chimneys were built with no liner at all. Either situation is a fire and carbon monoxide risk.

Installing or replacing a chimney liner improves:

Fire safety
Draft and heating efficiency
Protection against moisture and structural damage
Compliance with local building codes

Which Chimney Liner is Right for You? A Maine Buyer’s Guide

Maine winters put chimneys through hard freeze-thaw cycles, so the liner you choose needs to hold up. The most common options are:

Stainless Steel Liners – Durable, corrosion-resistant, and suitable for wood, oil, gas, and pellet appliances. The most common choice for relining in Maine.
Aluminum Liners – A lower-cost option approved for certain gas appliances only. Not suitable for wood or oil.
Clay Tile Liners – Common in older homes. Inexpensive when a chimney is built, but difficult and costly to repair or replace once the chimney is standing.
Cast-in-Place Liners – A cement-based mix poured around a form inside the chimney. It seals cracks and can strengthen older masonry chimneys.

A certified technician should inspect your chimney before recommending a liner, because the fuel type, flue shape, and chimney condition all narrow the choices.

How Chimney Liners Are Sized

Liner size matters as much as liner type. A liner that is too large lets smoke cool and slow down, which causes poor draft and faster creosote buildup. A liner that is too small restricts the flue and can push smoke and gases back into the house.

Wood and pellet stoves – The liner is matched to the stove’s flue collar. A stove with a 6-inch outlet gets a 6-inch liner. It should never be smaller than the outlet.
Open fireplaces – The liner is sized to the fireplace opening, generally about one-tenth to one-eighth of the opening’s area, depending on flue shape and chimney height.
Oil and gas appliances – The liner is sized from the appliance’s BTU input and the manufacturer’s venting tables. When an oil or gas furnace is replaced with a more efficient model, the existing flue is often too large and needs to be relined. See our oil and gas boiler and furnace relining service for details.

Chimney height, the number of bends, and whether the flue serves one appliance or two also affect sizing. That is why we measure on site before quoting.

Breaking Down the Cost of Lining a Chimney in Maine

Several factors affect what you will pay for chimney liner installation:

Type of liner material
Chimney height and flue size
Insulation wrap, which many installations require for safe clearances
Removal of an old or broken tile liner
Roof access and labor
Additional repairs, such as a new chimney cap, crown, or top plate

On average, chimney liner installation in Maine ranges from $2,000 to $4,500. Stainless steel liners, the most common and durable option, typically cost between $2,500 and $3,500.

Top Tips for Finding Chimney Liner Installers Near You in Maine

Whether you are in Portland, Sanford, or anywhere in York or Cumberland County, look for these qualities when choosing a chimney liner installer:

What Happens During a Chimney Liner Installation? Step-by-Step

Here is what to expect from first visit to final check:

Initial Inspection – Your chimney is evaluated for damage, draft, and liner compatibility. A chimney sweeping and inspection is usually the first step.
Recommendation & Estimate – The technician recommends the right liner type and size and gives you a written cost breakdown.
Scheduling & Permits – Some towns, especially Portland and other larger communities, may require a permit.
Installation Day – Any old liner is removed, and the new liner is lowered into the flue, connected, insulated where required, and sealed at the top.
Final Testing – The system is checked for proper draft, tight connections, and safety compliance.

Most installations are completed in one to two days, depending on the complexity.

Do You Need a New Chimney Liner? Look for These Signs

Call for an inspection if you notice any of the following:

Crumbling or missing clay tile pieces in the firebox
Rust stains or moisture in the firebox
Smoky odors or poor draft
A fireplace or wood stove that does not heat as well as it used to
A new oil or gas furnace or boiler connected to an old flue
Damage found during a chimney inspection

Chimney Liner Installation FAQs

How much does chimney liner installation cost in Maine?

Most chimney liner installations in Maine cost between $2,000 and $4,500. Stainless steel liners typically run $2,500 to $3,500. Chimney height, insulation, and any repairs needed at the top of the chimney move the price up or down.

How long does it take to install a chimney liner?

Most installations are completed in one to two days. Jobs that need an old tile liner removed or masonry repairs can take longer.

Does my chimney liner need to be insulated?

Often, yes. Insulation keeps flue gases hot for better draft, reduces creosote, and helps the liner meet required clearances to nearby wood framing. Your technician will tell you whether your chimney needs it.

Can I install a chimney liner myself?

Liner kits are sold online, but sizing, insulation, and connections must meet code and manufacturer requirements, and many insurers expect professional installation. A certified installer also confirms the chimney is safe to use when the job is done.
