Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterChimney Cleaning in SeaTac, WA
A Level 2 chimney inspection and cleaning in SeaTac typically runs $280-$380 for a standard masonry fireplace with camera documentation included. Most SeaTac appointments are scheduled within a week during burning season, with dispatch coordinated from our Seattle office. Call (425) 696-0387 for a written estimate before any work begins.
SeaTac’s mid-century housing stock - built largely between 1950 and 1975 for airport workers - presents chimney conditions we don’t see in newer suburbs. Original clay tile liners are now past their 50-year design life, and Puget Sound’s maritime moisture has been wicking into mortar joints for decades. When we sweep a SeaTac chimney, we’re often documenting deterioration that started before the homeowner was born. That’s why every visit includes NFPA 211 Level 2 camera inspection and a photo record under Haven Standard Clause 4.
Why SeaTac Homes Are Different
SeaTac incorporated in 1990, which means much of its residential construction predates modern chimney codes. We regularly find field-fabricated caps, non-standard liner repairs, and gas conversions that were never formally inspected. Homeowners in the McMicken Heights and Angle Lake areas often assume their chimney was “taken care of” by a previous owner, only to discover undocumented modifications during our camera scan.
The local climate compounds the problem. SeaTac hosts the official NOAA station for the Seattle metro, recording 37-38 inches of annual rainfall in long, low-intensity Pacific fronts. This isn’t dramatic weather - it’s relentless moisture that degrades crowns, flashing, and mortar joints faster than drier inland climates. Intermittent winter cold snaps below freezing cause freeze-thaw spalling in water-saturated brick. In SeaTac, water damage is the dominant finding on cleaning inspections, not creosote buildup alone.
The tight clustering of this era’s housing around the airport corridor means chimney sweeps here routinely discover conditions that turn a standard cleaning visit into a repair conversation. We’ve found collapsed clay tile liners in homes on both sides of International Boulevard, and improperly capped flues in the Riverton-Boulevard Park zone that had been admitting rainwater for years.

Written scope and price are delivered before any work begins. Chimney Repair in SeaTac
Fireplace Services in SeaTac
Many SeaTac homes have had fireplaces retrofitted with gas inserts, sometimes leaving original clay liners unlined and uncapped properly. We inspect these conversions for proper venting, check for abandoned flue openings that admit moisture, and verify that inserts are connected to code-compliant liners. Camera documentation shows exactly what was found. Fireplace Services in SeaTac

AfterChimney Cap & Crown in SeaTac
SeaTac’s original masonry chimneys were built with simple wash crowns and often no cap at all - standard practice in the 1960s, but inadequate for decades of Puget Sound rainfall. A proper cap and sound crown are the primary defense against the moisture damage we document on nearly every SeaTac inspection. Chimney Cap & Crown work here is usually preventive maintenance that has been deferred too long.
Cap Installation
Signs you need it
No cap is present, or the existing cap is rusted through, improperly sized, or missing mesh screening that keeps animals and debris out of the flue.
What it costs in SeaTac
Standard single-flue stainless steel cap installation in SeaTac typically runs $180-$340, with multi-flue custom caps ranging $340-$580 depending on flue count and chase dimensions.
How we do it
We measure your flue or chase top precisely, fabricate or source a cap from our Famco and Copperfield inventory with proper mesh and overhang, and secure it with stainless steel fasteners that won’t corrode in SeaTac’s wet climate.
Crown Repair
Signs you need it
The concrete wash crown has hairline cracks, spalling, or pooling water, or you notice brick deterioration and interior water staining below the roofline.
What it costs in SeaTac
Crown repair with specialized masonry coating in SeaTac generally falls between $280-$480 for minor cracking, while full crown rebuilds range $580-$1,200 depending on chimney width and accessibility.
How we do it
We grind out cracked concrete to sound substrate, apply a bonding layer, and finish with a sloped, overhanging crown formulation designed for freeze-thaw resistance in Pacific Northwest conditions.
What Chimney Cap & Crown Costs in SeaTac
| Item | Typical range in SeaTac |
|---|---|
| Single-flue cap installation | $180-$340 |
| Multi-flue custom cap | $340-$580 |
| Crown repair / coating | $280-$480 |
| Full crown rebuild | $580-$1,200 |
Do I need a cap if my chimney already has a crown?
Yes. A crown sheds water from the chimney top, but a cap covers the flue opening itself to block rain, animals, and debris from entering the flue directly. In SeaTac’s 37-inch annual rainfall environment, both components are necessary.
How long does a crown repair last?
A properly applied crown coating lasts 10-15 years in SeaTac’s climate; our full rebuilds with modern formulations are designed for 20+ years of freeze-thaw cycling. Both are covered by our 365-Day Done Right Promise.
Chimney Liner & Rebuild in SeaTac
SeaTac’s 1950s-1970s clay tile liners are now well past their typical 50-year service life, and we’ve found collapsed tiles, cracked sections, and gaps at mortar joints in homes throughout the McMicken Heights and Riverton areas. Original liners in these airport-worker homes were never designed for modern gas insert conversions, creating venting hazards we document with camera evidence. Chimney Liner & Rebuild work in SeaTac often starts with a cleaning inspection that reveals liner failure the homeowner didn’t know existed.
Stainless Steel Liner
Signs you need it
Clay tile pieces appear in the firebox, the flue shows gaps or misalignment on camera inspection, or a gas insert was installed without a proper liner connection.
What it costs in SeaTac
Stainless steel liner installation in SeaTac typically ranges $2,400-$4,200 for a standard fireplace flue, with variations for height, diameter, and whether the liner needs insulation for UL 1777 listing.
How we do it
We measure the flue precisely, source DuraFlex or HeatShield-compatible stainless steel in the correct diameter, lower the liner with proper top and bottom terminations, and document the completed installation with photos under Haven Standard Clause 4.
Partial Rebuild
Signs you need it
The upper chimney shows significant spalling, leaning, or mortar loss, but the lower structure and foundation remain sound and the liner is still serviceable or newly replaced.
What it costs in SeaTac
Partial rebuild of a SeaTac chimney above the roofline generally runs $3,800-$7,500 depending on height, brick matching requirements, and whether scaffold access is needed for multi-story homes.
How we do it
We dismantle to sound masonry, salvage matching brick where possible, rebuild with proper bonding and weep details, and install a new crown and cap assembly sized for SeaTac’s rainfall load.
What Chimney Liner & Rebuild Costs in SeaTac
| Item | Typical range in SeaTac |
|---|---|
| Stainless steel liner installation | $2,400-$4,200 |
| Flexible liner (offset flues) | $2,800-$4,800 |
| Partial rebuild (above roofline) | $3,800-$7,500 |
| Full chimney rebuild | $8,500-$18,000 |
Can I just keep using my clay tile liner?
Clay tile liners in SeaTac’s 50-70 year old homes are past design life; even intact tiles show thermal fatigue and mortar joint gaps on camera. We document actual condition and recommend replacement only when camera evidence shows failure.
Does a gas insert need its own liner?
Most gas inserts in SeaTac were installed into original clay flues without proper liner connection, creating venting hazards. We verify with camera inspection and install a listed liner system sized to the insert’s BTU output when needed.

FAQs About Chimney Cleaning in SeaTac
Permits are required for structural rebuilds and new liner installations in SeaTac; standard cleaning and cap replacement typically do not trigger permit requirements. We handle permit documentation on rebuild jobs and note any code compliance issues found during inspection.
We typically book SeaTac inspections within 3-7 days during burning season, with faster availability September through October before demand peaks. Our Seattle office coordinates dispatch and sends a text when your technician is en route.
