What This Means for Your Blairstown Chimney
Older homes, older flues
Where homes date from before the 1940s, chimneys often have clay tile flues, soft lime mortar or no liner at all, and decades of freeze and thaw open the joints. A yearly inspection catches cracked tiles and failing mortar while the fix is still small. Read: What Is a Clay Flue Liner?
Oil heat and the chimney
Where a home heats with oil, the boiler sends soot and acidic exhaust up the masonry chimney all winter, so the flue needs regular cleaning, and an unlined or oversized flue often needs a stainless steel liner sized to the boiler. Read: How Often Should an Oil Boiler Chimney Be Cleaned?
Gas boilers and water heaters
Gas appliances burn cleaner than oil, but their exhaust is wet. In an old masonry flue that water condenses, breaks down mortar and flue tiles, and shows up as white staining or crumbling brick. A liner made for gas protects the chimney. Read: Does a Gas Water Heater Need a Chimney Liner?

Half of the homes in Blairstown were built before 1975, and 17% date from before 1940, so a good share of chimneys here were built to older standards, with clay tile liners and crowns that are now decades old. With about 135 freezing nights a year in Warren County, water that gets into a crack freezes and widens it again and again, which is why we check the crown and flashing on every visit.
