Joint repair
Open mortar joints between clay tiles are sealed so gases stay inside the flue.
Many liner problems in Sunbury homes, from open joints to small cracks, can be fixed in place while bigger damage may call for a new stainless liner instead. Dial (272) 238-4101 to talk with a local chimney pro about your flue.
Most liner damage is hidden inside the chimney, out of sight from the firebox and the roof. Clay tiles stacked inside the masonry are the most common liner, though many chimneys now have stainless. Both can fail, just in different ways.
Clay tiles crack from thermal shock, especially when a cold flue is suddenly heated by a hot fire or a chimney fire. Mortar joints between tiles also wear out, leaving gaps where heat and gases can escape into the masonry. Stainless liners can corrode from acidic condensation, wrong fuel grades or 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. Keep CO alarms on every level of the home, and if an alarm sounds, get everyone into fresh air and call 911.
If the problem goes deeper than it first looked, a Sunbury chimney sweep may also recommend chimney liner installation or chimney inspection.

Call nowRepairing a liner starts with seeing exactly what is wrong.
The flue is swept first, since soot and creosote hide cracks and gaps. That also removes fuel for a chimney fire.
The sweep scans the liner with a camera to locate cracks, gaps and corrosion. You can ask to see the video yourself.
The sweep explains whether the liner can be repaired or needs replacement. Cost and the age of the chimney play a role too.
Open joints and cracks are sealed with a heat resistant resurfacing compound, often drawn up the flue with a foam applicator. Stainless steel is typically replaced, not resurfaced.
A follow up camera scan confirms the repair covers the damaged areas. The draft is checked as well.

Badly damaged liners are relined instead of repaired to restore a safe flue.
Damaged tiles near the crown are replaced where freeze and thaw damage is worst.
A ceramic based coating is applied inside the flue to seal cracks and rough surfaces where damage is moderate.
Damaged stainless liners or sections are replaced and the connections resealed.
Clay flue tiles form the inner liner of many chimneys, and they are tough but brittle. They crack from heat shock, chimney fires and settling, and the mortar joints between them erode over time. Tiles near the top are the easiest to replace, since they can be reached from the crown.
Tiles further down cannot be swapped without opening the chimney, so resurfacing or relining is the usual route. If you are in Sunbury, call (272) 238-4101 and mention any recent chimney fire or tile pieces found in the fireplace. After a camera scan, the sweep can explain your options.
Chimneys in Sunbury see plenty of heat during the heating season, and that is when liner damage tends to happen. In Sunbury and neighboring towns like Northumberland, Winfield, Selinsgrove and Lewisburg, sweeps regularly find open joints and cracked tiles during inspections, which is why a yearly inspection matters for the parts of the chimney you cannot see.

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: 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. Wind driven rain from coastal storms finds any gap in flashing, too. That is why chimney cleaning in Sunbury is usually booked in the fall, before the first cold night.
A chimney problem fixed early rarely spreads to the masonry, the liner or the house.
Local sweeps see the same chimney types and weather wear across Sunbury and nearby towns.
