Chimney & Crown Repair in Issaquah
Issaquah's mountain rain and runoff soak chimneys all winter, and freeze-thaw on cold nights cracks crowns and crumbles mortar — especially the soft, century-old mortar in Olde Town. Left alone, water tracks into the firebox and the home, and on a historic chimney that damage compounds fast.
We rebuild and seal crowns, repoint with mortar matched to the era of the masonry, replace spalled brick, redo failed flashing, and waterproof. The goal is a weather-tight chimney that keeps the mountain rain out and, on older homes, keeps the character intact.

Chimney & Crown Repair — your questions
Why does my Issaquah chimney leak?
Usually a cracked crown, failed flashing, soft old mortar, or porous brick soaking up the heavy mountain rain and runoff. We find the actual entry point and seal it rather than patching the ceiling stain.
Can you repair an old Olde Town brick chimney?
Yes, and it's a specialty. We repoint with appropriate mortar, rebuild failing crowns, and reline where needed — restoring safety while preserving the historic look.
Is waterproofing worth it in Issaquah?
Definitely. With this much rain and freeze-thaw, a breathable masonry sealer significantly slows water intrusion and brick spalling — far cheaper than rebuilding later.
