Chimney Liner Installation Avonmore, PA
A Avonmore chimney sweep can reline your chimney with a liner sized to the appliance and insulated where the system calls for it. One call to (724) 817-2006 reaches a nearby sweep who installs liners.
Inside most chimneys is a liner, the tube that actually carries smoke and flue gases to the top. It keeps heat from reaching wood framing next to the chimney, protects the brick and mortar from corrosive gases and gives the appliance a flue of the right size to draft well. Some older chimneys were built unlined, and others have clay tiles that have cracked over the decades.
Most liner installations start with one of these situations. Clay tiles crack after chimney fires, shift as the house settles and lose mortar at the joints, while some chimneys never had tiles to begin with. Installing an insert, stove or high efficiency furnace often means the old flue is the wrong size.
Industry standards based on NFPA 211 call for a Level 2 inspection when an appliance is changed or after a chimney fire. The inspection tells you whether relining is truly needed and what kind of liner suits the chimney. Seeing the inside of the flue makes the decision much easier.
Chimney Liner Installation is often paired with chimney liner repair and chimney inspection, depending on the cause.

What happens during a liner installation
Here is how a sweep usually handles a liner installation.
Scan the chimney
A camera is run through the flue to check the existing tiles, offsets and obstructions. This confirms what kind of liner the chimney needs.
Match the appliance
Sizing follows the appliance it will serve, since too big or too small both cause problems. The length is measured from the appliance to the top of the chimney.
Clear the path
The flue is swept and any loose tile or obstruction is cleared so the liner can pass. Some chimneys need old tiles broken out to fit an insulated liner.
Install the liner
The liner goes in from the top, with insulation added where the system requires it. Insulating it helps draft and reduces creosote and condensation.
Connect the appliance
At the top, a plate and cap close off the flue, and at the bottom the liner connects to the appliance. The connections keep gases from leaking into the old flue.
Confirm venting
A draft test confirms the new liner is working. This is also a good time to test your CO alarms.
What is included
Types of chimney liners
Rigid stainless liners
Rigid stainless sections join together in straight chimneys which suits wood burning appliances well.
Flexible stainless liners
Flex liners snake through chimneys with bends and offsets which makes them the most common relining choice.
Liner insulation
An insulation wrap or poured insulation surrounds the liner where the system or chimney calls for it.
Furnace flue liners
A properly sized liner for a water heater left alone after a furnace upgrade to keep combustion gases moving out of the house.

Stainless Steel Chimney Liner Avonmore, PA
A stainless steel liner is the standard choice for most homes that need a new flue. Flexible liners make it possible to reline chimneys with offsets, while rigid pipe gives a smooth, heavy wall. Liners are sold as tested systems, with grades suited to wood, gas or oil.
Stainless liners are often paired with insulation, either a wrap or a poured mix, which keeps flue gases warm and can be required for clearance to combustibles. At the top, a sealing plate and cap keep rain and animals out. In Avonmore, a stainless liner is a common upgrade when installing an insert or wood stove.

Chimney Relining Avonmore, PA
Chimney relining is the process of lining a flue again when the original liner is cracked, missing or unsuitable. The most common triggers are chimney fires, settling cracks, missing mortar and appliance changes. Most chimneys can be relined from the roof without opening walls.
When you call (724) 817-2006, tell the sweep what vents into the chimney, such as a fireplace, stove, furnace or water heater. A furnace replaced with a high efficiency model that vents through the wall can leave the water heater alone in an oversized flue, which leads to poor draft and condensation. Relining with the right size solves the draft and moisture problems.

Chimneys in this climate
Cold winters keep fireplaces, wood stoves and oil burners working for half the year or more. Masonry takes the worst of it from the freeze and thaw cycle: rain and melting snow soak into the crown and joints, then freeze and push them apart, and each winter widens the cracks a little more. Nor'easters drive rain sideways into flashing and mortar that looked fine in summer. Most homeowners in Avonmore, PA schedule a sweep in early fall, and a repair check after a hard winter.

Chimney Liner Installation FAQ
Can an insert vent into an existing chimney without a liner?
An insert should vent into a properly sized liner, not just into the open smoke chamber. Skipping the liner tends to cause draft trouble and creosote. The insert manual will list the venting requirements.
Why does my water heater flue need relining after a furnace upgrade?
An orphaned water heater is one left venting alone into a chimney that used to serve both it and the furnace. That flue is now too big for the water heater, so gases cool, draft weakens and condensation can damage the masonry. A smaller liner sized for the water heater fixes it, and working CO alarms are essential in the meantime.
How long will a new chimney liner hold up?
A stainless steel liner is a long term fix when it suits the fuel and is kept clean. Chimney fires, heavy creosote and corrosive condensation are what shorten their life. Annual inspection helps catch problems early.
Should I replace clay flue tiles with stainless?
Clay tile liners are built into the chimney when it is constructed and last a long time if they stay intact, but they can crack from heat shock, settling or a chimney fire. Stainless steel liners are installed later, from the top, and are used to reline chimneys whose tiles are damaged or missing. A sweep can tell you whether repair or relining makes more sense.
Why would a chimney need a liner?
The liner is what contains the heat and gases from the fire or appliance. Without a sound liner, the chimney is less safe and wears out faster. A camera inspection answers the question for your chimney.
