What We Repair
Seattle Chimney Repair Services
Seattle's pre-war masonry chimneys — from Craftsman bungalows in Ballard to Capitol Hill apartments — have 65 to 120 years of Pacific Northwest weather behind them. We repair, repoint, and restore the original masonry. Written assessment every visit.
Crown Repair & Rebuild
Seattle's freeze-thaw cycling — 14 to 23 events annually in most neighborhoods — works continuously on chimney crowns. Flush crowns on pre-war construction are especially vulnerable. We repair cracked crowns and rebuild those that have failed beyond patching.
Mortar Repointing
Original lime-based mortar on Seattle's older chimneys carbonates over decades, losing binding strength. Repointing restores the weathertight seal. Critical: the replacement mortar must match the original lime formulation — Portland cement is harder than the brick and causes spalling.
Flashing Repair & Reseal
Atmospheric river storms drive water horizontally into Seattle rooflines. Flashing failure at the chimney-roof interface is one of the most common sources of interior water damage. We repair and reseal step flashing, counter flashing, and saddle flashing.
Liner Repair & Relining
Original clay tile liners in Seattle's pre-war chimneys develop cracks and joint failures over decades. HeatShield liner repair and stainless steel relining are both options — which is appropriate depends on the extent and location of the damage.
Post-Earthquake Assessment
The Nisqually earthquake (2001) and multiple minor seismic events since have left latent damage in older Seattle masonry chimneys — mortar joint cracking, liner offsets, and hairline fractures in brick courses that may not be visually obvious without professional assessment.
Historic Brick Matching
Seattle's pre-war chimneys used local brick from Renton and Pacific Coast Brick — a specific size, texture, and color that modern brick doesn't replicate exactly. Where repairs require new brick, we source material that matches the original character of the chimney.
How It Works
Our Seattle Chimney Repair Process
Written Assessment
We assess the full chimney system — firebox, liner, smoke chamber, crown, flashing, and exterior masonry — and document findings in writing before any repair work is recommended.
Repair Plan
We explain what needs repair, why, and in what order of priority. Structural and safety issues first. Cosmetic issues noted. No pressure to address everything at once.
Repair Work
Work performed by our own crew — not subcontracted. Original material character respected throughout. Lime-compatible mortar used on lime mortar chimneys.
Post-Repair Report
Written documentation of what was repaired, how, and with what materials. A record you can reference at the next inspection or provide to a buyer.

Chimney Repair in Seattle — FAQ
Common questions from Seattle homeowners. Don't see yours? Call us.
Seattle's residential building stock is overwhelmingly pre-war or early postwar. The Craftsman bungalow neighborhoods — Ballard, Fremont, Wallingford, Phinney Ridge, Green Lake — were built between 1905 and 1930. Capitol Hill's apartment blocks and rowhouses date to the same era. Queen Anne, First Hill, and Madison Park have significant Victorian-era construction. These masonry chimneys are 65 to 120 years old, and they were built before seismic considerations were part of any residential building code.
The Nisqually earthquake of 2001 caused widespread latent damage to older Seattle masonry that homeowners still discover today — most commonly during a chimney inspection or sweep that surfaces a liner offset or mortar joint crack that's been there for two decades. Hairline fractures in brick courses aren't always visible without scaffolding, and damaged liner joints aren't visible without a camera or careful flashlight inspection from below. This is why the inspection component of any Seattle chimney service matters as much as the cleaning or repair work.
Seattle chimney repair also intersects with permit requirements in certain situations. The Seattle Department of Construction and Inspections (SDCI) requires permits for chimney rebuilds above the roofline, liner replacements on gas-connected appliances, and structural masonry modifications. We're familiar with the Seattle permit process and can advise on what your specific project requires.
"Seattle chimneys tend to need extra care to maintain their original character during rebuilds. These older masonry systems were built with real craft — matching that when we work on them takes more time, but it's the right way to do it." — Sean, Lead Technician
