When brick faces flake, crack, or crumble off your chimney, that's spalling — and in the Puget Sound it's usually water damage rather than age alone. Individual damaged bricks can be cut out and replaced with matching units before the problem spreads. The trick is timing: a handful of spalled bricks is a quick swap, but once whole courses are failing you're replacing a large section. Here's what brick replacement actually costs around Seattle and how to catch it early.
What chimney brick replacement costs in Seattle
The number comes down to how many bricks are compromised. Spot brick replacement — cutting out a few spalled or cracked bricks and setting matching replacements — runs about $299–$900. Extensive brick replacement, where entire courses or a full face have deteriorated, runs $900–$2,500. Matching older Seattle and Tacoma brick sometimes takes sourcing salvage units, and chimney height plus roof access affect labor. You get a firm written quote before we cut a single brick.
Spotting spalling and failing brick
- Flaking, pitting, or missing faces on the brick — pieces on the roof or ground below.
- Bricks that look hollowed, crumbling at the corners, or noticeably darker where they stay wet.
- Cracks running through bricks rather than just the mortar joints.
- Efflorescence and persistent damp patches on the stack.
- A chimney that looks like it's lost its clean, square edges near the top.
Why brick spalls in our wet climate
Brick is porous, and in Seattle it spends much of the year soaking up rain. When a saturated brick hits a freeze-thaw cycle, the water inside expands and blows the face right off. Shaded, north-facing chimneys and those under mossy roofs stay wettest and spall fastest. Failed mortar joints make it worse by letting even more water in. That's why we often pair brick replacement with repointing — fixing the brick without sealing the joints just invites the damage back.
Replace bricks before you replace the chimney
Spalling doesn't stop on its own. Each wet-cold season claims more faces, and once the structural bricks go soft the only fix is rebuilding a section of stack. Swapping damaged bricks early — and correcting the water source — keeps a small repair from turning into major masonry work.
