Chimney Crown Repair in Greater Seattle, WA
What We Do
Crown Repair & Replacement
The crown is the concrete cap at the top of your chimney stack. Once it cracks, water gets in — and with Western Washington's freeze-thaw cycles, small cracks become big problems fast. We inspect, diagnose, and fix it before you're looking at major masonry damage.

Crown Rebuild With New Caps
A chimney where the original mortar-wash crown had failed entirely. We rebuilt the crown with a fresh slope, installed three new stainless caps over the flue openings, and sealed everything against PNW moisture. Drag the handle to see before and after.

Our Process
How a Crown Repair Project Runs
1. Roof-level assessment
We inspect the crown from above — it's the only reliable way to assess its condition. From the ground, even a failing crown can look fine.
2. Repair vs rebuild call
Based on what we see, we recommend either crown sealing (for moderate damage) or full crown rebuild (for structural failure). Written estimate, no upsell.
3. Execution
Sealing is typically a same-day job; rebuild takes longer with proper concrete cure time. Tarps and roof protection so the work stays clean.
4. Walk-through & warranty
We show you what was done, explain the warranty terms, and tell you what to keep an eye on going forward.
Signs to Watch For
Your Crown May Need Attention If...
Visible cracks from the ground
Even hairline cracks let water in. If you can see them, get them looked at.
Water in the firebox after rain
Not always the flashing. If the crown is compromised, water runs straight in.
White staining on the chimney exterior
Efflorescence — mineral deposits left behind as water migrates through masonry.
Spalling or loose bricks near the top
Classic sign that freeze-thaw damage has already started working its way down.
Frequently Asked Questions
Questions about chimney crown repair? We're happy to help — call or text anytime.
Why the Crown Matters
The chimney crown is the concrete slab that seals the top of your chimney stack. It's designed to shed water away from the flue opening and protect the masonry below. When it cracks — and in the Pacific Northwest, it will — water seeps into those gaps, freezes, expands, and widens them. Left alone, that turns into spalling bricks, damaged mortar, and repairs that cost a lot more than a crown fix would have.
We see a lot of neglected crowns on Eastside homes. The damage isn't always visible from the ground, which is why annual inspection is worth it.
