Chimney Rebuild in Seattle
Some chimney damage can be repaired. Severe structural damage requires rebuilding. We inspect to determine which one your chimney actually needs — partial rebuild above the roofline, full structural reconstruction, or targeted repair that avoids rebuilding altogether.

Our Work — Chimney Rebuilds & Restoration
Signs Your Chimney May Need Rebuilding
These conditions usually mean targeted repair isn't enough — but inspection confirms it
Leaning chimney
Pulling away from the house, even slightly. Get it looked at.
Spalling brick across multiple courses
Faces flaking off across most of the chimney, not one or two bricks.
Major mortar joint failure
Receded half an inch or more across most joints, or gone in places.
Cracked structure
Vertical cracks through the brick faces, on more than one side.
Major water damage throughout
White staining everywhere and masonry that never dries out.
Chimney separation from house
A visible gap between the chimney and the siding.
Repeated repairs that keep failing
Same chimney fixed three times. At some point repair stops being the answer.
Biggest Decision
Partial Rebuild vs. Full Rebuild
Not every chimney rebuild is the same scope. The right choice depends on where the damage is concentrated and whether the lower structure is still sound. We assess condition section-by-section and recommend the smallest scope that fully restores the chimney.
Partial Rebuild
Above-Roofline Reconstruction
The portion of the chimney above the roof faces the most weather — and that's where most damage concentrates. A partial rebuild dismantles the upper courses (above the flashing) and rebuilds them with matched materials. The lower structure inside the house is preserved.
When it works:
- •Damage concentrated at and above the roofline
- •Lower structure (firebox up through attic) is sound
- •Crown, upper mortar joints, or cap area has failed
- •Foundation and lower brick are stable
Preserves more of the original chimney. Reduced project timeline.
Full Rebuild
Firebox to Cap Reconstruction
When damage extends through the entire chimney — or when the structure is leaning, settling, or has compromised lower courses — a full rebuild is the safer answer. The chimney is dismantled from the firebox course upward and reconstructed with new matched materials throughout.
When it's necessary:
- •Leaning chimney or shifted foundation
- •Major damage extending below roofline
- •Widespread mortar joint failure throughout
- •Post-fire structural compromise
Largest scope. Code-compliant from ground up.
Our approach: Camera inspection and physical assessment first. Partial rebuild whenever the lower structure is sound. Full rebuild only when the damage genuinely requires it. We rebuild only when repair can't restore the chimney.
Matched Materials, Clean Results
Partial or Full — We Match Your Masonry
We source brick and mortar to match your existing chimney as closely as possible. When we rebuild, the repair should blend in, not announce itself — and be built to last another generation.

Not Every Damaged Chimney Needs Rebuilding
A rebuild is a big project. Before we recommend one, we confirm targeted repair can't restore the chimney. Many chimneys that look bad from the curb are actually repairable through tuckpointing, brick replacement, crown repair, and flashing work.
Our approach: Repair first, rebuild only when necessary. We assess the structural condition during inspection and choose the smallest scope that genuinely restores safe function. If we tell you it needs a rebuild, it's because targeted repair won't fix the problem long-term — not because rebuilding is the most profitable option.
Repair is usually enough when:
- ✓Damage is localized to specific bricks or joints
- ✓Crown is cracked but underlying masonry is sound
- ✓Flashing has failed but chimney structure is intact
- ✓Mortar deterioration is partial (less than ~30% of joints)
- ✓Chimney is plumb and not leaning
Rebuild becomes necessary when:
- ✓Structural cracking through multiple courses
- ✓Chimney is leaning or pulling away from house
- ✓Mortar has failed across most of the chimney
- ✓Widespread spalling across multiple sides
- ✓Post-fire structural damage confirmed by inspection
The Process
What Happens During a Chimney Rebuild
A chimney rebuild is a significant project. We walk you through every step so you know what to expect, what we're doing, and why.
01
Structural inspection
Camera scan of the flue, exterior masonry evaluation, foundation check, and documentation of what's failing. We share findings and recommend scope before any work starts.
02
Written scope & estimate
Detailed project scope: partial vs. full rebuild, materials, timeline, and total cost. You decide whether to move forward in your own time.
03
Site prep & protection
Drop cloths, roof protection, and containment for masonry debris. We protect surrounding surfaces inside and out before anything comes apart.
04
Demolition of damaged sections
Damaged courses are removed brick by brick from the top down. Salvageable materials are saved for matching. Existing flashing and roofing are documented for reintegration.
05
Masonry reconstruction
New courses laid with matched brick and properly mixed mortar. Plumb, level, and aligned to original profile. Liner integrated correctly for the appliance being vented.
06
Crown / flashing / liner integration
New crown poured with proper slope. Flashing reintegrated for a watertight roofline seal. Liner sized and installed correctly. Cap installed with spark arrestor.
Final safety check: Every rebuild ends with a complete safety check — gas leak test (if applicable), draft verification, and a final camera scan of the new liner. You receive written documentation of the work and confirmation the system meets current code.
Common Causes of Chimney Failure
Most chimney rebuilds trace back to one or more of these underlying causes
Long-term water intrusion
Years of small leaks through cap, crown or flashing.
Freeze-thaw cycle damage
Saturated brick freezes and pushes itself apart, winter after winter.
Neglected masonry
Decades without tuckpointing. Targeted repair can't catch up.
Structural shifting
Settling, framing movement, or seismic shift.
Age deterioration
Pre-1960 brick and lime mortar were softer to begin with.
Failed crown allowing top-down damage
A cracked crown is where most of this starts.
Seattle Weather & Masonry Damage
Pacific Northwest climate is uniquely hard on chimney masonry — and it's why Seattle sees more chimney rebuilds than drier regions.
Sustained moisture exposure
Masonry stays saturated fall through winter.
Heavy rainfall driving water through cracks
Small cracks become full leaks in sustained rain.
Repeated freeze-thaw cycles
Sometimes daily during a cold snap.
Moss & biological growth on chimneys
Roots work into the joints and hold water against the brick.
Older Seattle homes everywhere
Ballard, Queen Anne, Capitol Hill, Wallingford, Beacon Hill, Madison Park.
Marine air exposure
West Seattle, Magnolia, Madrona — salt accelerates metal corrosion.
