Chimney Liner Installation DuBois, PA
A DuBois chimney sweep can reline your chimney to protect the masonry and keep heat away from the framing around it. One call to (814) 913-0171 reaches a nearby sweep who installs liners.
A chimney liner is the channel inside the chimney that carries smoke and combustion gases up and out. 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.
There are a few reasons a chimney gets a new liner. The original clay tiles may be cracked from age, settling or a chimney fire, or the chimney may never have been lined. 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. That reveals whether the existing tiles can be repaired or need to be replaced, and it shows the route a new liner will take. You can ask the sweep to walk you through the video.
If the problem goes deeper than it first looked, a DuBois chimney sweep may also recommend chimney liner repair or chimney inspection.

Call nowThe process
What happens during a liner installation
Relining a chimney is a careful job that starts well before the liner goes in.
Scan the chimney
The sweep inspects the flue from top to bottom, usually with a video camera. It decides between repair and relining.
Size the liner
The right diameter depends on the stove, insert, furnace or fireplace being vented. The full height of the flue is measured too.
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
A flexible liner is fed down the flue, while rigid sections are joined as they go. Many liner systems are tested with insulation for clearance to combustibles.
Finish the top
A tee or connector joins the liner to the appliance, and a top plate seals the crown. Every joint is secured so gases stay inside the liner.
Test the draft
The sweep checks the draft and looks for any leaks. This is also a good time to test your CO alarms.
What is included
Types of chimney liners
Liner insulation
Insulation is wrapped around the liner or poured into the space around it which improves draft and limits creosote.
Cast in place liners
A cement based mix is poured around a form inside the chimney to create a smooth new flue in a single solid lining.
Flex liners
A flexible liner works in chimneys that are not perfectly straight and come in grades matched to the fuel.
Furnace flue liners
A properly sized liner for a water heater left alone after a furnace upgrade stop condensation from damaging the chimney.

Stainless Steel Chimney Liner DuBois, PA
A stainless steel liner is the standard choice for most homes that need a new flue. Flexible stainless goes around offsets in a chimney, and rigid stainless suits straight runs. The sweep picks a grade of stainless that suits the fuel the appliance burns.
Insulation around the liner helps flue gases rise and keeps the outside of the chimney cooler. At the top, a sealing plate and cap keep rain and animals out. Many DuBois chimneys get a stainless liner when an old fireplace is converted to an insert.

Chimney Relining DuBois, PA
A chimney is relined when the existing flue cannot safely vent the appliance. The most common triggers are chimney fires, settling cracks, missing mortar and appliance changes. In most cases the work is done from the top without tearing into the house.
When you call (814) 913-0171, tell the sweep what vents into the chimney, such as a fireplace, stove, furnace or water heater. An orphaned water heater, left behind when a new furnace vents elsewhere, is a common reason to reline. A smaller liner brings the draft back where it should be.

How the weather here affects chimneys around DuBois
Cold winters keep fireplaces, wood stoves and oil burners working for half the year or more. The hardest thing on brick here is not the cold itself but the constant swing above and below freezing: water soaks into brick, mortar joints and the crown on a mild day, freezes overnight and expands, which is how cracks, loose bricks and leaks start. Nor'easters drive rain sideways into flashing and mortar that looked fine in summer. That is why chimney cleaning in DuBois is usually booked in the fall, before the first cold night.

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 sweep sizes the liner from the insert specifications.
What is an orphaned water heater?
When a home switches to a high efficiency furnace that vents out the side of the house, the water heater may be left as the only appliance using the chimney. A big flue with little heat going up it leads to backdrafting and moisture damage. Relining with the right size solves the problem, and CO alarms are a must.
How long does a stainless steel liner last?
A stainless steel liner is a long term fix when it suits the fuel and is kept clean. Keeping it swept and using dry wood helps it last. The liner manufacturer usually gives guidance on care.
What is the difference between a clay liner and a stainless liner?
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. Replacing clay tiles with new clay means rebuilding, so stainless is the common choice for relining. A sweep can tell you whether repair or relining makes more sense.
Do I need a chimney liner?
The liner is what contains the heat and gases from the fire or appliance. Unlined chimneys or broken liners can let heat or carbon monoxide escape. An inspection shows whether your current liner is in good shape.
