Chimney Crown Repair & Waterproofing in Oak Harbor, WA

What crown repair & waterproofing involves in Oak Harbor

The crown is the concrete slab on top of the chimney that sheds rain away from the brick. When it cracks — which it eventually does in Oak Harbor's climate — water pours straight into the masonry, and freeze-thaw cycles turn small cracks into major damage.

We repair and replace crowns and apply breathable waterproofing that keeps rain out while letting trapped moisture escape. In Island County, crown repair and waterproofing are the single best way to prevent expensive masonry damage.
