Seattle’s older chimneys often hide decades of creosote, soot, and debris that block airflow and pose fire risks. Our high-powered vacuums and rotary brushes clear every flue passage, including the hard-to-reach sections behind your fireplace. We don’t just scrape the surface—we inspect for cracks, gaps, or deteriorated liners that Seattle’s damp air worsens over time. For homes with original brickwork, we use soft-bristle tools to avoid damaging historic masonry while ensuring no residue remains. After service, you’ll notice better draft, fewer cold drafts from the fireplace, and a chimney that’s safe for the next heating season. Includes a free post-service inspection report.

We diagnose liner issues with a 4K camera, measuring gaps, cracks, or offset joints that let heat escape into your walls. Our stainless steel liners are sized to your flue’s exact dimensions, eliminating draft problems and reducing the risk of carbon monoxide leaks. For historic brick chimneys, we offer heat-resistant mortar repairs to match original construction. All liners come with a 20-year warranty against defects, and we provide before/after thermal imaging to prove the upgrade.
Request this service →Seattle’s older chimneys often suffer from eroded mortar joints, cracked bricks, or missing caps—all of which let water seep in and accelerate decay. We repoint mortar with a mix matched to your home’s age, using lime-based formulas for pre-1900s brick and modern Portland cement for post-1950s builds. Cracked bricks are replaced with salvaged or custom-cut stock to maintain authenticity. Our chimney caps are custom-fitted to block rain, pests, and debris while allowing proper airflow. Every repair includes a 5-year workmanship warranty, and we document the process with photos for your records.
Request this service →Water is the #1 enemy of Seattle’s older chimneys, causing bricks to spall, mortar to crumble, and liners to fail. We apply a breathable, vapor-permeable waterproofing sealant that repels rain while allowing trapped moisture to escape—critical for homes in Ballard or Queen Anne where humidity lingers. Our chimney caps are designed to withstand Seattle’s wind-driven rain, with mesh screens to block birds and debris. We also install spark arrestors to prevent embers from landing on your roof. All caps are custom-fabricated to match your chimney’s profile, ensuring a seamless fit.
Request this service →A fireplace that smokes, a chimney that leaks, or a flue that feels drafty often signals deeper problems—like a collapsed liner, blocked flue, or deteriorating damper. We use thermal imaging to detect heat loss, moisture meters to find hidden leaks, and smoke tests to identify draft issues specific to Seattle’s microclimates. For homes with multiple fireplaces, we map each flue’s performance to ensure none are compromised. Our diagnostic reports include photos, measurements, and prioritized repair recommendations, so you can address issues before they worsen. Free estimates for all diagnostics.
Request this service →Seattle’s winter storms can crack chimney crowns, dislodge bricks, or collapse liners—leaving your home vulnerable to water damage or fire hazards. We respond within 24 hours for emergency calls, with crews stocked for same-day repairs. Whether it’s a collapsed flue tile, a shattered crown, or a chimney leaning from ground movement, we stabilize the structure and implement temporary fixes to prevent further damage. All emergency work includes a follow-up inspection to ensure long-term safety. Licensed, insured, and Seattle-bonded for your peace of mind.
