Chimney Flashing & Leak Repair in Connecticut

A leaking chimney almost always starts at the flashing. A Class Chimney repairs and replaces flashing, seals leaks, and waterproofs your chimney to keep water out for good.

Why It Matters

Stop the Leak Before It Spreads

Water intrusion is the number-one cause of chimney damage — from rusted dampers and stained ceilings to failed mortar and rotted framing. Most leaks begin where the chimney meets the roof: the flashing.

We find the true source of the leak, repair or replace the flashing, and apply breathable waterproofing to protect the masonry.

Signs Water Is Getting In

Look for ceiling or wall stains near the chimney, a damp firebox, musty odors, or visible rust on metal components. The earlier a leak is caught, the cheaper the fix.
