With more waterfront than any other community on the Chain O’Lakes, Johnsburg is a beautiful place to own a home — and a place where chimneys work a little harder against the elements. If you’re seeing a stain, a smell, or a drip near the fireplace, water is the likely culprit.
Why Lakeside Chimneys Leak
Waterfront and near-water homes face constant moisture: humidity off the lake, wind-driven rain, and the freeze-thaw cycles that come with Illinois winters. All of it works on the most exposed parts of the chimney — the crown, the flashing, and the cap. A sound cap and crown aren’t optional near the water; they’re your first line of defense.
The Usual Suspects
When we trace a Johnsburg leak, it almost always comes back to one of four things: a cracked crown, lifted or corroded flashing where the chimney meets the roof, a missing or rusted cap, or porous brick drinking in moisture. We find which one (sometimes more than one) and fix the cause, not just the stain.
Catch It Early
A small leak is an affordable repair. Left alone, water deteriorates mortar, rusts metal components, and can damage the liner and surrounding framing — turning a minor fix into a major one. An annual inspection is the cheapest insurance there is.

Frequently Asked Questions
Why does my lakeside chimney leak more than my neighbor’s inland?
More moisture exposure — humidity, wind-driven rain, and freeze-thaw all accelerate crown, flashing, and cap wear near the water.
What should I check first?
The cap and crown. A missing cap or cracked crown is behind a large share of chimney leaks.
