Chimney Liner Installation Sharon, PA
A chimney sweep in Sharon can install a new liner in a flue that is unlined, cracked or the wrong size to protect the masonry and keep heat away from the framing around it. Dial (724) 509-7140 to talk with a local chimney pro about relining.
The liner is what smoke travels through on its way out of the house. Without one, heat and acidic condensation attack the masonry, and gaps can let heat or carbon monoxide escape into the home. Many older homes, especially those built before the middle of the last century, have no liner at all.
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. Changing appliances is another big one, because a flue sized for an old fireplace is usually too large for a modern insert or furnace.
Before relining, the chimney should get a thorough inspection, usually a Level 2 inspection with a camera run up the flue. It helps decide between repair and relining, and between flexible and rigid stainless. Seeing the inside of the flue makes the decision much easier.
Depending on what the sweep finds, chimney liner installation in Sharon, PA can go hand in hand with chimney liner repair and chimney inspection.

Call nowThe process
The chimney relining process
Relining a chimney is a careful job that starts well before the liner goes in.
Scan the chimney
The inside of the chimney is checked so the route and condition are known. The findings shape the rest of the job.
Measure the flue
The right diameter depends on the stove, insert, furnace or fireplace being vented. The length is measured from the appliance to the top of the chimney.
Prepare the chimney
Creosote and debris are cleaned out first, and broken tiles may be removed to make room. Tight flues sometimes need old tiles removed.
Lower it in
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.
Make the connections
A tee or connector joins the liner to the appliance, and a top plate seals the crown. The connections keep gases from leaking into the old flue.
Final check
A draft test confirms the new liner is working. Make sure working CO alarms are in place near sleeping areas.
What is included
Chimney liner options
Insulated liners
An insulation wrap or poured insulation surrounds the liner to keep flue gases warm and meet clearance requirements.
Flexible stainless liners
A flexible liner works in chimneys that are not perfectly straight and are common for inserts, stoves and gas appliances.
Rigid stainless liners
Straight flues can take rigid stainless pipe which suits wood burning appliances well.
Cast in place liners
Cast in place liners are formed inside the old chimney with a heat resistant mix in a single solid lining.

Stainless Steel Chimney Liner Sharon, PA
Stainless steel is the most common material for relining today, because it is strong, resists corrosion and works with wood, gas and oil. It comes in flexible coils for chimneys with bends and rigid sections for straight flues. The grade of stainless and the wall thickness are matched to the fuel, and systems are tested and listed as complete kits with their parts.
Insulating a stainless liner improves draft, cuts creosote buildup in wood flues and is part of many systems. At the top, a sealing plate and cap keep rain and animals out. Homeowners in Sharon often choose stainless when adding an insert, stove or new furnace.

Chimney Relining Sharon, PA
Chimney relining is the process of lining a flue again when the original liner is cracked, missing or unsuitable. It is often recommended after a chimney fire, when clay tiles crack, or when a new appliance needs a different flue size. Relining is usually far less disruptive than rebuilding the chimney.
Before relining, it helps to know which appliances share the chimney. If the furnace was upgraded recently, the water heater may now be venting into a flue that is too large. A properly sized liner fixes that.

What the local climate does to a chimney
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, and each winter widens the cracks a little more. Nor'easters drive rain sideways into flashing and mortar that looked fine in summer. That is why chimney cleaning in Sharon is usually booked in the fall, before the first cold night.

Chimney Liner Installation questions
How long does a stainless steel liner last?
Stainless liners are built to last many years when they are sized right and swept regularly. Chimney fires, heavy creosote and corrosive condensation are what shorten their life. The liner manufacturer usually gives guidance on care.
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. Venting an insert into an oversized clay flue leads to poor draft and heavy creosote. The sweep sizes the liner from the insert specifications.
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. A big flue with little heat going up it leads to backdrafting and moisture damage. A smaller liner sized for the water heater fixes it, and working CO alarms are essential in the meantime.
What is the difference between a clay liner and a stainless liner?
Clay tiles were the standard in many older chimneys, and they hold up well until they crack. Stainless is the usual replacement because it goes in from the roof without tearing down the chimney. Minor tile damage can sometimes be repaired instead.
Why would a chimney need a liner?
Chimney liners keep heat and gases inside the flue, away from wood framing and the brick itself. Unlined chimneys or broken liners can let heat or carbon monoxide escape. A sweep can check the flue and tell you where you stand.
