Our Fireplace Services team knows Seattle’s housing stock inside and out. We’ve worked on the tight alley-access Craftsman bungalows in Fremont, the stacked townhomes on Capitol Hill with flat roofs and minimal clearance, and the mid-century ranches in Rainier Valley with their 1970s wood stove inserts. James Wilson, our owner and lead technician, has been inside thousands of Seattle chimneys since 2008. We don’t split our attention across roofing or HVAC — chimneys are what we do, and Seattle’s persistent wetness is what we prepare for.

Our Fireplace Services in Seattle
Wood Burning Fireplace Service
Seattle’s wood-burning fireplaces face a unique stress cycle: the Puget Sound Clean Air Agency can impose mandatory burn bans for days or weeks, leaving flues cold and damp, then homeowners light up the moment bans lift without checking what accumulated during dormancy. We inspect for moisture-damaged flue tiles, bird nesting from the idle period, and wet creosote that’s stickier than what dry-climate sweeps encounter. In Ballard and Wallingford, where pre-WWII brick chimneys dominate, we regularly find moss colonies holding moisture against mortar joints — that’s not a cleaning issue you can ignore. A typical wood-burning fireplace sweep and inspection in Seattle runs $220–$280.
Gas Fireplace Service
Gas fireplaces in Seattle see heavy use during burn-ban periods when wood burning is restricted. We service pilot assemblies, thermocouples, and venting systems, and we check for moisture intrusion in gas flues that share chimneys with abandoned wood-burning systems. Many Capitol Hill and Fremont conversions involve fitting modern gas inserts into 1920s flues with tight clearances — work that demands precise measurement and proper liner sizing. Gas fireplace service in Seattle typically costs $180–$260 for standard maintenance, with conversion projects running $2,800–$4,500 depending on liner and insert requirements.
Fireplace Insert Installation & Service
Seattle’s 1970s energy-crisis wood stove inserts — common in Rainier Valley and West Seattle ranches — created a secondary inventory of metal liners that need independent cleaning and inspection. We remove inserts to check for creosote buildup in the bypass chamber, inspect for rust at the collar connection, and verify that the liner terminates properly above the roofline. For new insert installations, we size Olympia Chimney stainless liners to your specific appliance and flue dimensions, not generic kits. Insert service runs $240–$320; full installation with liner typically falls between $3,200–$5,800.
Damper Repair & Replacement
Seattle’s damp climate destroys dampers. We’ve replaced hundreds of rusted throat dampers in Ballard and Fremont homes where decades of moisture exposure have seized the mechanism or eaten through the plate. A stuck damper isn’t just inefficient — it’s dangerous, trapping smoke and carbon monoxide in your living space when you need draft control most. We install replacement dampers that seal properly against Seattle’s wet-season downdrafts, and we can retrofit top-sealing dampers where throat access is compromised by insert installations. Damper repair in Seattle typically costs $280–$420; full replacement with a top-sealing model runs $520–$780.
Fireplace Conversion
Converting a wood-burning fireplace to gas in Seattle requires navigating both the physical constraints of vintage flues and the regulatory reality of burn bans. We’ve converted dozens of Ballard and Wallingford brick chimneys — 1920s construction with lime mortar, original clay flue tiles, and often minimal clearance to combustibles. James Wilson measures every flue by hand, specifies the correct DuraFlex or Copperfield liner system, and coordinates gas line connection with your licensed plumber. The result is a conversion that drafts safely through Seattle’s wet winters and complies with Puget Sound Clean Air Agency requirements. Full conversions in Seattle typically range $3,500–$6,200.
Firebox Repair
Seattle’s freeze-thaw cycles are mild compared to the Midwest, but chronic moisture saturation in firebox brick causes a different failure mode: gradual mortar erosion behind the facing, leading to loose bricks and heat escape into wall cavities. We repoint fireboxes with refractory mortar rated for the thermal cycling of Pacific Northwest dampness, and we replace cracked refractory panels in prefabricated units. Firebox repair in Seattle generally runs $340–$680 for repointing; panel replacement in prefab units costs $420–$890.
Trusted Brands We Service in Seattle
We stock and install parts from Olympia Chimney, Famco, and Copperfield — brands that hold up to Seattle’s moisture load, not off-brand alternatives that rust out in three seasons. When we install a Gelco rain cap on your Capitol Hill townhouse or a DuraFlex liner in your Ballard Craftsman, we’re specifying materials we’ve watched perform through 150+ days of annual rainfall. That parts availability means most Seattle repairs finish same-visit. We don’t order-and-wait while your wet flue sits exposed another week.
Common Fireplace Services Problems We See in Seattle Homes
- Moisture-damaged flue tiles from unsealed crowns. Seattle’s constant drizzle penetrates cracked chimney crowns, saturates the flue structure, and spalls clay tiles from the inside out. We catch this during inspection — before you light a fire and send hot gases through compromised tile channels.
- Wet creosote accumulation after burn-ban dormancy. When Puget Sound Clean Air Agency bans lift and homeowners ignite without inspection, damp creosote that accumulated during weeks of disuse can ignite incompletely or flare dangerously. We remove it with rotary brushing designed for sticky Pacific Northwest deposits, not dry-climate methods that leave residue behind.
- Moss and lichen colonies widening mortar joints. In neighborhoods like Fremont and Wallingford, we’ve seen moss root systems penetrate lime-based mortar to depths that accelerate water infiltration. This isn’t cosmetic — it’s structural damage that demands repointing and moisture-sealing intervention.
- Failed dampers from rust and corrosion. Seattle’s maritime wetness corrodes steel damper mechanisms faster than inland climates. A seized damper discovered on the first cold night of the season leaves you choosing between smoke-filled rooms and no fire at all.

FAQs — Fireplace Services in Seattle
Seattle’s summer drizzle and marine layer keep relative humidity high enough for moss and lichen to colonize mortar joints year-round. We install weep screws and moisture-sealing caps during peak season so your flue is protected before the heavy rains return — waiting until October means your chimney has already absorbed months of passive moisture.
Yes — schedule your cleaning before burn-ban season begins, typically late September. When bans lift and Seattle homeowners rush to light fires, our calendar fills with emergency calls from people who discover blocked flues or damp creosote only after ignition. Call (866) 541-8697 in early fall to beat the post-ban rush.
Most will, with proper liner sizing and clearance verification. We’ve converted dozens of Ballard Craftsmans — the key is measuring the actual flue interior, not assuming original specs, and specifying a listed liner system like DuraFlex that maintains safe clearances to combustible framing. James Wilson handles these measurements personally. Call for a free feasibility check.
Inspect your damper annually — Seattle’s moisture typically causes functional problems every 5–8 years for steel throat dampers, sooner if the chimney crown leaks. Top-sealing dampers last longer because they’re protected from direct flue moisture exposure, which is why we often recommend them as replacement options. Call (866) 541-8697 if your damper sticks, rattles, or won’t fully close.
A Gelco multi-flue cap with extended screen height and a steep-pitched lid for runoff. Capitol Hill townhomes often have minimal clearance between cap and roof membrane, so we specify spark-arrestor mesh tight enough for ember protection but open enough to prevent lint and debris clogging in Seattle’s leaf-heavy fall. Flat roofs also pool water — we verify cap overhang doesn’t channel runoff toward the crown. Call for a custom measurement.
