Relining when needed
If too much of the liner is damaged, relining is the better option to restore a safe flue.

Chimney Liner Repair Delmont, PA
Many liner problems in Delmont homes, from open joints to small cracks, can be fixed in place so the flue seals again and heat and gases stay where they belong. One call to (724) 412-9258 reaches a nearby sweep who handles liner repair.
Because the liner sits inside the masonry, problems usually show up only during an inspection. Older chimneys usually have clay tile liners set end to end with mortar joints, while newer or relined ones may have stainless steel. Both can fail, just in different ways.
Chimney fires are a leading cause of cracked tiles, since the heat can be intense enough to split clay. Open joints between tiles are just as important as cracks, because gases and heat pass through them. Stainless liners usually fail from corrosion or damage after a chimney fire.
A damaged liner is a safety problem, not just a maintenance issue. Heat escaping through a cracked liner can reach framing, and gases can find their way indoors. Working carbon monoxide alarms are essential, and if one goes off, leave the house and call 911 from outside.
Many chimney liner repair calls in Delmont also turn up a need for chimney liner installation or chimney inspection.

How chimney liner repair works
Here is how a sweep usually approaches a damaged liner.
Clean the liner
The flue is swept first, since soot and creosote hide cracks and gaps. Any loose tile pieces are removed.
Run a camera
The sweep scans the liner with a camera to locate cracks, gaps and corrosion. You can ask to see the video yourself.
Choose the repair
Depending on the damage, the options range from joint repair or resurfacing to replacing sections or relining. The goal is a liner that seals the full length of the flue.
Seal the flue
Damaged tiles near the top may be replaced, and gaps are filled with a ceramic based sealant. Stainless liners with damage usually need the damaged section or the whole liner replaced.
Check the result
A follow up camera scan confirms the repair covers the damaged areas. The appliance draft is tested too.
What is included
Common liner repairs
Liner resurfacing
Resurfacing compounds coat the inside of the liner to close small cracks where damage is moderate.
Stainless liner replacement
A corroded or crushed stainless liner is swapped for a new one and the connections resealed.
Mortar joint sealing
Gaps between tiles are filled with heat resistant material without taking the chimney apart.
Upper tile repair
Cracked tiles at the top of the flue are replaced and sealed to the crown.

Flue Tile Repair Delmont, PA
Flue tiles are the clay sections stacked inside a masonry chimney, and they are the most common liner in older homes. They crack from heat shock, chimney fires and settling, and the mortar joints between them erode over time. Damage at the top of the flue is the easiest to reach and fix.
Damage below the top is typically sealed from inside the flue or covered by a new liner. If you are in Delmont, call (724) 412-9258 and mention any recent chimney fire or tile pieces found in the fireplace. A video inspection settles which route to take.

Chimneys in this climate
Winters here are long and cold, and the heating season usually runs from October well into April. 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 Delmont, PA schedule a sweep in early fall, and a repair check after a hard winter.

Chimney Liner Repair questions
Should I repair or replace my chimney liner?
That depends on the type of liner, how much damage there is and what the chimney vents. Limited cracks are often repairable, but a liner with damage along much of its length is usually replaced. Ask to see the inspection video before deciding.
Should I stop using the fireplace if the liner is cracked?
A cracked liner can let heat reach framing and let carbon monoxide into the house, so it is wise to hold off on fires until it is assessed. Many repairs are done without major work. Keep working CO alarms in the home regardless.
What can be done about a cracked liner?
The answer depends on how much of the liner is damaged and what it is made of. If too many tiles are cracked or out of line, a new liner is the safer fix. A camera inspection shows which option fits.
Why do flue tiles crack?
A chimney fire can crack clay tiles in minutes because of the intense heat. Thermal shock from a hot fire in a cold flue, settling of the house and freeze and thaw at the top of the chimney also crack tiles. Regular sweeping and burning dry wood reduce the risk.
How do I know if my chimney liner is damaged?
Most liner damage is hidden, which is why inspections with a camera are so useful. Clues include tile pieces in the firebox, smoke leaking into other rooms, moisture stains near the chimney and poor draft. After any chimney fire, have the liner inspected before using it again.
