What This Means for Your Commack Chimney
Winters are hard on masonry
Cold winters with many freeze and thaw cycles work water into brick and mortar every year. Keep the chimney swept and inspected once a year, keep a cap on top, and fix small cracks before they spread. Read: How Often Should a Chimney Be Swept?

Half of the homes in Commack were built before 1964, and 1.1% 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 98 freezing nights a year in Suffolk 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.
