Chimney Liners & Relining in Connecticut
Properly sized venting systems for fireplaces, stoves and compatible heating appliances.
A chimney liner forms the venting pathway inside the chimney. When an existing flue is missing, damaged, deteriorated or incorrectly sized, a properly selected liner system can restore a suitable route for combustion gases while helping protect the surrounding chimney structure.

Common relining reasons
4 Reasons a Chimney May Need to Be Relined
The older CT Chimney Repair page identified four useful reasons for relining. Those remain good starting points, but the final decision should be based on the chimney condition, appliance and installation requirements.
1
The Chimney Is Unlined
Older masonry chimneys may have no flue liner or may no longer have a complete, serviceable lining system.
2
The Existing Liner Is Damaged
Cracked clay tiles, missing sections, open joints or other deterioration can compromise the existing flue.
3
The Flue Is the Wrong Size
An oversized or undersized flue can affect draft and venting performance, especially after an appliance change
4
A New Appliance Requires It
A replacement boiler, furnace, stove or insert may require a venting system sized and approved for the new appliance.
Chimney liner applications
Chimney Liner & Relining Services
One liner does not fit every chimney. Fuel type, appliance output, flue height, chimney construction, connector configuration and manufacturer requirements all influence the correct system.
Stainless-steel systems
Stainless-Steel Chimney Relining
Stainless-steel liners are commonly used to reline existing masonry chimneys. The liner diameter, alloy, insulation and connection components are selected for the appliance and fuel being vented.
- Flexible or appropriate listed stainless-steel liner
- Top plate, termination and cap components
- Appliance connector, tee or stove adapter as required
- Insulation when required by the listed system or installation
Fireplace applications
Fireplace Chimney Liners
Fireplace flues can require relining when clay tiles are cracked, missing, deteriorated or otherwise unsuitable. Fireplace applications must be sized to the fireplace and venting configuration rather than simply matching the old flue dimensions.
Solid-fuel appliances
Wood Stove & Pellet Appliance Liners
Wood and pellet appliances commonly vent through listed liner systems sized for the appliance. Proper connection, liner diameter, insulation and termination are important to system performance and installation compliance.
Heating appliance venting
Oil, Gas & Propane Appliance Relining
Heating appliances can require relining when the masonry chimney is oversized, deteriorated or incompatible with the appliance. The liner must be selected for the fuel, appliance input and venting requirements.
Existing flue problems
Damaged Clay Flue Tile Solutions
Cracked or deteriorated clay tiles do not automatically tell you which repair method is best. The chimney height, appliance, flue condition and access determine whether a stainless-steel relining system is an appropriate solution.
Complete liner termination
Top Plates, Caps & Liner Components
A complete relining project includes the correct top termination and appliance connection components. The cap, top plate, storm collar or other components depend on the liner system and chimney configuration.
Sizing and insulation
A Chimney Liner Must Match the Appliance
Relining is not simply a matter of dropping a metal tube down the chimney. The liner needs to be sized for the fireplace or appliance, selected for the fuel being burned and installed as part of a listed venting system.
Insulation can also be an important part of a relining project. Whether it is required depends on the listed liner system, chimney construction, clearances and application.
Diameter
Correct sizing supports proper draft and appliance venting.
Alloy
The stainless-steel material must be compatible with the fuel and venting conditions.
Insulation
Wrap or pour-in insulation may be required depending on the system and installation.
Connections
Adapters, tees, connectors and terminations must match the appliance and listed liner components.
Decision support
Repair the Existing Flue or Install a New Liner?
The right answer depends on the type and extent of the existing flue damage and what the chimney serves.
Existing Flue Repair May Be Considered When…
The defect is limited, accessible and the original flue remains appropriate for the appliance.
- Localized clay-tile or joint concerns
- The flue remains properly sized
- No widespread deterioration is present
- The chosen repair method is appropriate for the chimney and application
Relining May Make More Sense When…
The existing flue is missing, substantially damaged, poorly sized or no longer suitable for the appliance.
- The chimney is unlined
- Multiple flue tiles are cracked or deteriorated
- A new appliance needs a different flue size
- The old flue cannot be reasonably restored for the intended use

Helpful Chimney Service Answers
Common Chimney Service Questions
What chimney services does CT Chimney Repair provide?
The service hub covers chimney repair and rebuilding, cleaning, chimney liners, caps and chase covers, dampers, waterproofing and water protection, inspections, plus related fireplace repair and restoration services.
Why is my chimney leaking even if the flashing looks okay?
Water can enter through more than the roof flashing. The crown, cap, masonry, mortar joints and other areas can all contribute, so leak diagnosis should consider the complete chimney system.
When does a chimney need to be relined?
Relining may be considered when an existing flue liner is damaged, missing, deteriorated, improperly sized, or when a fireplace or heating appliance requires a different venting configuration. The correct liner system depends on the appliance, fuel type, chimney construction and installation requirements.
Should a chimney be waterproofed after masonry repairs?
In many situations a breathable masonry water repellent can be considered after appropriate repairs and curing. It should not be used as a substitute for fixing cracked crowns, failed mortar or other physical defects.
How do I know whether my chimney needs repair or rebuilding?
Localized deterioration may be repairable, while widespread spalling, movement or extensive mortar and brick failure may make partial or complete rebuilding the better long-term option. The condition needs to be evaluated before deciding.
When does a chimney need a new liner?
Relining may be considered when an existing flue is damaged, missing, incorrectly sized or when a new appliance requires a different venting configuration.
Do all chimneys need a cap?
Many masonry chimneys benefit from an appropriately sized cap to help limit rain, debris and animal entry. Wood-framed chimney chases often use a fabricated metal chase cover instead of a masonry crown.
