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 Sweep Across SeaTac
A proper chimney sweep in SeaTac, WA typically runs $180 to $340, and the job should include a full camera inspection with photos you keep. We know that sounds like a claim most companies make. We put the price in writing before the first tool comes off the truck, and you get a photo report of your flue’s condition inside. Call (830) 251-4560 and you’ll get a live person, not a voicemail tree.
SeaTac is home to a split housing stock: mid-century ramblers along old residential streets near the airport, and newer townhome and condo rows built in the last fifteen years. That means our crews in SeaTac often sweep a full masonry flue on one street, then a factory-built zero-clearance metal chimney on the next. Different tools, different inspection levels, same standard of work. We know both systems cold.
Most of SeaTac sits under the flight path in a damp marine climate. Wind-driven rain and airborne grit from constant airport traffic land on chimney caps, crowns, and flashing in ways inland King County chimneys rarely see. A sweep here is not a quick brush. It is a real inspection of how your particular system has held up against SeaTac’s weather.
We serve the whole city: the residential streets off International Boulevard, the neighborhoods near Angle Lake, the townhome clusters south of South 200th Street, and the older homes around Bow Lake. If you need a Chimney Sweep, we’ll give you a straight answer on price and schedule before you hang up.

Why Flint Chimney Sweep Is SeaTac’s Preferred Chimney Sweep Company
We have been cleaning chimneys since 2002 as part of the Garrison Partners family of independently owned chimney service companies. SeaTac homeowners call us for a simple reason: we put the scope, the price, and the guarantee in writing before any work begins. No door-creeper pricing. No “while we’re here” surprises. The number on the invoice is the number you approved.
Every Chimney Repair - SeaTac we perform carries a written guarantee valid for a full year from the service date. If a covered repair fails inside that year, we come back at no charge. No argument, no re-quoting. That is the Garrison Standard, and it applies to every job our technicians run in SeaTac, whether it is a starter townhome off South 188th Street or a rambler near SeaTac Airport.
Our technicians arrive uniformed and background-checked. You know exactly who is walking through your door. Your phone calls are answered by a live person around the clock, not a voicemail that says we’ll get back to you Monday. And we use professional-grade materials from chimney trade brands like HeatShield, Gelco, and Famco, specified by the job, not by whatever is left in the truck.
Chimney Sweep Certified in SeaTac
A Chimney Sweep Certified job in SeaTac means we remove the creosote and soot buildup inside your flue, inspect the liner for cracks and separation, check the cap and crown, and hand you a photo report showing what we found. In SeaTac’s marine climate, creosote builds faster than most homeowners expect because wood burns cooler when the air is damp. That sticky second-degree glaze coats flue walls and becomes a fuel source for chimney fires.
A standard certified sweep in SeaTac runs $180 to $340, depending on flue type and buildup. The price is agreed before we book. No one guesses at the door.
How We Handle Creosote
Creosote has three grades. First degree is flaky soot, second is sticky tar-like glaze, and third is a hard tar coating that cannot be brushed out. In SeaTac we see a lot of second-degree buildup from homeowners burning cordwood that never fully dried. Our sweep removes first- and second-degree creosote with the right rods and brushes, and if we find third-degree, we’ll tell you plainly what that means and what the next step is. No scare tactics, no pressure.
We also handle soot removal for homes where the buildup is light but still worth clearing before burning season. Annual sweeping is the cheapest insurance against a chimney fire, and NFPA 211 still calls for a yearly check even if you “only burned a few times.”
Level 1 and Level 2 Inspections
A Level 1 inspection is the quick look a homeowner gets during a routine sweep. A Level 2 inspection is a camera run through the flue, and it is what we recommend for SeaTac homes that have not been inspected in years, or any time there is a change in use, a new appliance, or a chimney fire scare. The camera shows liner cracks, spalling, failed flashing, and animal blockage that a basic visual check misses. In SeaTac’s damp climate, a hairline liner crack can let moisture into the flue liner and masonry, and you won’t know until the damage is expensive.
Gas Fireplace Cleaning in SeaTac
Gas Fireplace Cleaning in SeaTac means removing dust and debris from the log set, checking the pilot and burner, verifying draft, and running a combustion check. A lot of SeaTac homeowners assume gas means no service needed. That is not true. A dirty gas log set with blocked ports burns inefficiently and can produce carbon monoxide. CO does not announce itself. It takes a camera and a meter to spot the problem.
Gas fireplace cleaning in SeaTac typically runs $120 to $200, agreed in writing before we book. It is a straightforward job, but it matters more in sealed newer townhomes where airflow is tighter and CO can accumulate faster.
Why Gas Fireplaces Still Need a Chimney Sweep
Even without wood smoke, gas fireplaces deposit dust, pet hair, and fine acidic residue on the log set and glass. Over time that dulls the flame, clogs the burner ports, and stresses the thermocouple. The draft check matters too: a blocked or poorly drawing vent sends combustion gases back into the room. In SeaTac’s newer townhome rows, we run these gas fireplace checks alongside the wood-burning work on the same street.
If your gas fireplace has not been looked at in years, the cleaning is cheap compared to replacing a log set that corroded because nobody cleaned it.
Trusted Brands We Service in SeaTac
We install and work with professional-grade chimney materials, not whatever is on sale at the hardware store. On SeaTac jobs we specify HeatShield for flue liner repairs, Gelco and Famco for chimney caps and cleanout doors, and Olympia Chimney for relining components where the liner needs more than a patch. We stock common replacement parts locally, so a follow-up repair in SeaTac does not mean waiting two weeks on a shipment. When we quote a liner repair or cap replacement, the brand name goes in the written estimate. You can verify the product yourself before you approve a dollar.
Common Chimney Sweep Problems We See in SeaTac Homes
- Accelerated creosote from the marine climate. Damp cordwood burns cooler and leaves more second-degree creosote in SeaTac flues than you would see in a drier city like Spokane. Homeowners who burn “seasoned” wood that sat all winter in the rain often have no idea how fast that glaze built.
- Wind-driven rain on crowns and caps. SeaTac’s position under the flight path means constant airborne grit and frequent driving rain. Chimney crowns and caps here take a beating, and we regularly find failed flashing on the windward side of SeaTac rooftops.
- Factory-built chimneys mistaken for masonry. SeaTac’s newer townhomes use zero-clearance metal chimneys. Sweeping those with masonry gear causes damage, and skipping the cap inspection means spalling and water entry go unnoticed. Our techs identify the system type before unwrapping a single rod.
- Neglected gas fireplaces. Homeowners who switched to gas and stopped scheduling. The log set cakes with dust, burner ports clog, and the draft check never happens until a CO detector goes off or the flame burns yellow.
Pricing for Chimney Sweep in SeaTac, WA
A standard chimney sweep in SeaTac runs $180 to $340. A gas fireplace cleaning runs $120 to $200. A Level 2 camera inspection added to a sweep typically runs $90 to $150, and if the flue has heavy third-degree creosote that needs more work, we quote that separately and in writing before any additional labor. Flue relining costs more, usually starting around $2,500 for a partial reline with HeatShield or Olympia Chimney components, but we never recommend relining without camera evidence you can see yourself.
What changes the price is flue type, access, and buildup. A clean one-story rambler with a straight masonry flue is the low end. A tall factory-built chimney with a steep SeaTac roof and third-degree glaze is the high end. Every quote is a written flat price agreed before booking. Call (830) 251-4560 for an exact number, and we’ll have it to you before the call is over.

FAQs About Chimney Sweep in SeaTac
Every year, even if you barely burn. NFPA 211 requires an annual inspection for wood-burning fireplaces and stoves, and SeaTac’s damp marine climate builds creosote faster than you would get in a drier area. Burning a few times still deposits first-degree creosote, and one wet season can turn that into second-degree glaze. Skipping a year does not usually cause a fire, but it lets a small liner crack or cap failure go unnoticed until the repair bill is five times the cost of a sweep. Call (830) 251-4560 and we’ll book your annual sweep at a written flat price.
Third-degree creosote is a hard, tar-like coating that cannot be removed with standard chimney brushes. It forms when second-degree glaze is left to bake over multiple burn seasons. You cannot brush it out. Removing it usually means chemical treatment or mechanical removal, and sometimes the flue needs relining if the creosote has degraded the liner. In SeaTac we see third-degree buildup most often in older ramblers where the previous owner burned wet wood for years. We’ll show you the camera photos before recommending anything.
We service both. Factory-built zero-clearance chimneys need different rods, brushes, and inspection methods than masonry, and our crews in SeaTac are equipped for both on the same day. We regularly run a masonry flue on a mid-century home near Angle Lake and then a factory-built unit on a newer townhome the same afternoon. The sweep is not the same process, but the written price and photo report are identical. Call us and tell us what you have; we’ll tell you what it costs.
You need a cleaning and inspection, yes. Not for creosote, but for dust, blocked burner ports, and draft. A gas fireplace that burns yellow or sooty is telling you the combustion is off, and a blocked vent can push carbon monoxide into the room. In SeaTac’s newer townhomes and condos, those are sealed tighter than older houses, so CO accumulates faster. A gas fireplace cleaning typically runs $120 to $200, and we check the draft and combustion with a meter, not just a visual. If your gas unit has not been looked at in years, book it.
No. We do not promise same-day service, and neither should anyone else. A proper sweep and Level 2 camera inspection is booked, not rushed. What we do promise is a live person on the phone when you call (830) 251-4560, a written flat price before any work starts, and a technician who arrives inside the window we gave you. In SeaTac, burning season runs roughly from October through March, so the smart move is booking your annual sweep in late summer or early fall, before the first fire of the season. We’ll tell you the first available slot when you call.
