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.

AfterFast, Reliable Chimney Cleaning & Sweep Across SeaTac
A Level 2 chimney sweep in SeaTac typically runs $220-$340 and includes a camera-scan inspection of the full flue, a written price before any work starts, and a documented photo record when we’re done. We dispatch crews to SeaTac from our Seattle office, and most appointments book within a week during sweep season. Call (425) 642-3485 for a written estimate with no obligation.
We’ve worked the neighborhoods west of International Blvd and along South 176th Street long enough to know SeaTac chimneys fail differently than chimneys in Burien or Des Moines. The 1950s-1970s ranch and split-level homes built for Sea-Tac Airport and Boeing workers now have fireplaces pushing 60 years old, and the low-frequency vibration from heavy cargo and commercial aircraft on final approach cracks mortar joints and shifts chimney caps in patterns you won’t find outside the primary flight corridor. Our Chimney Cleaning & Sweep team treats that as standard local knowledge, not a surprise to discover on your roof.
Why Level Two Chimney Kirkland Is SeaTac’s Preferred Chimney Cleaning & Sweep Company
We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and a significant share of those have been in SeaTac’s airport-corridor neighborhoods. Homeowners in the McMicken Heights and Angle Lake areas know our techs by the uniform and the camera rig, not by a sales pitch.
Our reviews from SeaTac customers consistently cite the same thing: the tech showed them the footage, named the price in writing, and did exactly what was scoped. No variance. That reputation is built on Clause 1 of the Haven Standard, which requires a written price, written scope, and written warranty before any work begins, and Clause 4, which requires a documented photo record on every job.
Response time to SeaTac is typically same-week during standard sweep season, with scheduling coordinated from our Seattle office. You’ll get a text when your tech is en route, along with their name and license number.
We know the local housing stock: original single-wythe brick masonry, clay tile flue liners at or past service life, and chimneys that have never been professionally inspected through multiple ownership changes since SeaTac’s incorporation in 1990. That local fluency means we spot the problems that matter and skip the ones that don’t.
Our Chimney Cleaning & Sweep Services in SeaTac
Level 1 Inspection
A Level 1 inspection in SeaTac covers readily accessible portions of the chimney, fireplace, and flue-what we can see without tools or demolition. For newer SeaTac homes or systems that haven’t changed since last inspection, this may suffice. We price Level 1s in SeaTac at $180-$240. If we find anything that warrants a closer look, we’ll show you why on camera and quote a Level 2 before proceeding.
Level 2 Inspection
Level 2 is our standard for every SeaTac home built before 1980, every real estate transaction, and every system that has experienced an operational change or chimney fire. We run a camera the full length of the flue liner, inspect the smoke chamber and damper, and walk the roof to examine the crown, cap, and flashing. In SeaTac, this almost always reveals mortar joint cracking and cap displacement from runway vibration, plus creosote condensation from low-intensity Pacific Northwest fires. A Level 2 in SeaTac runs $220-$340. The camera footage is yours, documented under Haven Standard Clause 4.
Creosote Removal
SeaTac’s mild winters mean homeowners tend to build smaller, cooler fires than in colder climates. That produces more creosote condensation, especially Class II and III glazed creosote, which is combustible and stubborn. We remove creosote with rotary poly or steel brushes matched to your flue liner type, and we verify completeness with the camera before we sign off. Heavy Class III removal in SeaTac can run $280-$420 depending on flue length and buildup severity. We quote it in writing after the Level 2 camera inspection, never before.
Soot Removal
Soot is the lighter, powdery byproduct of efficient combustion, but in SeaTac it often mixes with moisture from failed crowns or missing caps to form acidic sludge that accelerates liner deterioration. Our sweep process removes soot from the firebox, smoke chamber, damper, and flue, with debris contained by HEPA vacuum. Standard soot removal is included in our sweep pricing; if we find moisture damage or liner compromise, we document it and quote repair separately.
Annual Sweep
For SeaTac homeowners who burn regularly, an annual sweep is the NFPA 211 recommendation. Our annual service in SeaTac includes the Level 2 camera inspection, full creosote and soot removal, exterior condition check, and a written condition report with photos. We schedule recurring SeaTac customers ahead of burn season and text a reminder in September. Annual sweep contracts run $200-$280 for standard masonry flues.
Fireplace Cleaning
Fireplace cleaning addresses the firebox, grate, ash dump, and visible hearth area. In SeaTac’s older homes, we often find degraded firebrick and missing mortar that should be repaired before heavy use. Fireplace cleaning is typically bundled with our sweep service; standalone firebox cleaning runs $150-$220.

AfterTrusted Brands We Service in SeaTac
We source materials through Haven’s buying network to keep SeaTac customer prices honest. For liner repairs and relining, we use HeatShield cerfractory foam for resurfacing clay tile flues and DuraFlex stainless steel liners where full replacement is warranted. Chimney caps and exterior components come from Gelco and Olympia Chimney, with Famco hardware for custom flashing and termination fittings. These aren’t upsells; they’re the materials we stock so a SeaTac crew doesn’t wait on parts while your chimney sits open to the 38 inches of annual rain Sea-Tac Airport records.
Common Chimney Cleaning & Sweep Problems We See in SeaTac Homes
- Runway-vibration cap displacement. Technicians working west of International Blvd routinely find chimney caps shifted or cracked on otherwise well-maintained homes. The cumulative micro-stress from decades of 747 and heavy cargo traffic overhead makes cap inspection and re-setting a near-standard line item on SeaTac service calls.
- Clay tile flue liner spalling in 1960s ranches. SeaTac’s original airport-worker housing stock features clay tile liners now 50-70 years old. The tiles spall, flake, and gap, creating fire hazards and draft problems. We catch this with the Level 2 camera, show you the footage, and quote HeatShield resurfacing or DuraFlex relining only when the evidence supports it.
- Crown cracking from moisture plus vibration. SeaTac’s persistent marine overcast and heavy rainfall erode mortar crowns, while runway vibration accelerates the cracking. A compromised crown lets water into the smoke chamber, where it mixes with creosote to form acidic compounds that eat liners. We rebuild crowns with proper slope and overhang, documented before and after.
- Firebox-only sweeps that skip the smoke chamber. Some competitors clean what the homeowner can see and call it done. SeaTac’s low-intensity fires deposit heavy creosote condensation in the smoke chamber and damper, areas invisible from the hearth. Our sweeps reach the full system, verified by camera.

FAQs - Chimney Cleaning & Sweep in SeaTac
Your chimney sits under the north-south runway approach for Sea-Tac Airport, where decades of low-frequency vibration from heavy commercial and cargo aircraft crack mortar joints and displace caps at rates not seen in Burien or Des Moines outside the primary flight path. We inspect for this pattern on every SeaTac call and reset or replace caps with proper fasteners and sealant. Call (425) 642-3485 if your cap has shifted more than once.
You need a Level 2. Original clay tile liners in SeaTac’s 1950s-1970s housing stock are now 50-70 years old, well past typical service life, and spalling damage is invisible from the firebox. The Level 2 camera scan shows liner condition, gap spacing, and any mortar deterioration that a Level 1 cannot reach. We quote repair or relining only after you see the footage. Book a Level 2 at (425) 642-3485.
Demand camera evidence. Class III glazed creosote has a distinct shiny, tar-like appearance that shows clearly on our monitor. If a tech recommends chemical treatment or heavy removal without footage you can see, that’s a red flag. We classify creosote type during the Level 2 inspection, show you the camera stills, and quote removal in writing before touching a brush. Free Second Opinion on any competitor’s written estimate.
Sea-Tac Airport’s weather station records roughly 38 inches of rain annually with persistent marine humidity, conditions that erode mortar crowns, promote efflorescence and moss on masonry exteriors, and accelerate flashing corrosion. A cracked crown lets water into the smoke chamber, where it mixes with creosote to form acids that deteriorate liners. We inspect crowns and flashing on every SeaTac sweep and document condition with photos under Haven Standard Clause 4. Call (425) 642-3485 for a free estimate.
In SeaTac’s market, where many homes have traded multiple times since the city’s 1990 incorporation, missing inspection history is common. We treat every new-to-you home as a blank slate: Level 2 camera inspection, full documentation, and a written baseline report you can reference for future maintenance. If the chimney has never been swept, we’ll show you the creosote buildup and liner condition on camera, then quote only what’s evidenced. Start with a Level 2 at (425) 642-3485.
