As Swarthmore’s summer heats up, Midnight Blue Chimney Inc is reminding older-home owners that cracked brick, loose liners, and hidden creosote buildup can turn a cozy fireplace into a fire hazard. A quick inspection now prevents costly repairs later.
Why Swarthmore’s older brick chimneys need summer attention
Older brick chimneys in Swarthmore’s historic neighborhoods—like those near the Crum Woods or College Avenue—often hide hidden damage from decades of use. Summer humidity and sudden thunderstorms can worsen cracks in mortar joints or erode clay liners, letting water seep in and weaken the structure. My chimney’s bricks look fine from the outside—why should I worry about the liner? A masonry repair specialist can spot liner gaps that let heat escape into walls or allow water to pool behind the bricks, especially in homes built before 1950. Even a hairline crack in the liner can let flames lick the wood framing, turning a small repair into a full rebuild.
Three quick checks every Swarthmore homeowner can do now
Before firing up the fireplace this July, grab a flashlight and check these three spots on your Swarthmore chimney. First, look for white, flaky deposits on the smoke shelf—creosote buildup that’s a silent fire starter. Second, press gently on the bricks above the firebox; if they wiggle, the mortar’s failing. Third, shine the light up the flue from the basement: if you see daylight, the liner’s cracked. Found something?
