What This Means for Your Hopatcong Chimney
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?
Postwar homes and their chimneys
Homes built in the postwar decades often have a brick chimney with a mortar crown that was never meant to last. After decades of winters, crowns crack, caps go missing and flashing lets water in. These are quick, affordable fixes when caught early. Read: What Should You Do About a Cracked Chimney Crown?

Half of the homes in Hopatcong were built before 1962, and 7.2% 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 127 freezing nights a year in Sussex 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.
