Crown Rebuild & Waterproofing: What You Can't See Can Hurt You
The chimney crown is your chimney's first line of defense against the weather. It's the concrete slab at the very top that prevents water from entering the chimney structure. A cracked or deteriorating crown acts like a sponge, funneling water directly into the masonry, where it freezes, expands, and systematically destroys your chimney from the inside out.
Severe Water Damage: Water entering through crown cracks can rot adjacent woodwork, damage ceilings and walls, and lead to mold growth.
Freeze-Thaw Demolition: Trapped water freezes and expands, progressively breaking apart bricks and mortar, which can lead to structural collapse.
Flue System Failure: Water can bypass the crown and damage the flue liner, creating a fire and carbon monoxide risk.
Expensive Structural Repairs: Left unchecked, crown damage leads to the need for a complete, costly chimney rebuild.
We don't just patch the problem; we solve it. We remove the old, failed crown and cast a new, steel-reinforced concrete crown with proper drip edges to direct water away. We then apply a flexible, 100% waterproof sealant that protects against future cracking.
