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.

Why Flint Chimney Sweep Is Burien’s Preferred Chimney Sweep Company
We’ve been operating as Flint Chimney Sweep under the Garrison Partners family since 2002, and our Burien customers keep us busy for one reason: the price we give on the phone is the price on the invoice. Every job gets a written price before a single tool comes off the truck. The Garrison Code runs the same at every location – background-checked, uniformed technicians, professional-grade materials, and a written guarantee on every repair.
Burien homeowners have seen the other kind of chimney company. The one that quotes $99 and leaves at $900. The one that no-shows a 10am window. We hear those stories constantly from new customers in the mid-century rambler neighborhoods around Ambaum Boulevard and 1st Avenue South. Our answer is the 365-Day Done Right Promise: if a covered repair fails within one full year, we return at no charge. Written. Dated. Signed.
Response time to Burien is typically 2 – 4 business days for a standard sweep and Level 1 inspection. If you’re burning wood and notice smoke backing into the room, call and we’ll work you into the schedule as fast as the route allows. We do not promise same-day dispatch, because a sweep done right takes time and a rush job helps nobody. But we do answer the phone at 2am. Try us.
Chimney Sweep Certified in Burien
A Certified Chimney Sweep in Burien means the technician knows what a masonry flue in a 1960s rambler looks like after 30 years of intermittent use, and what to do about it. The job is straightforward: we run a wire brush through the flue to knock creosote and soot off the walls, vacuum it out, and inspect what’s left behind. Standard cost for a Burien single-family home is $169 – $239, depending on flue height and condition.
When Burien homeowners actually need it
Most Burien chimneys fall into one of two situations. Wood burners using the fireplace more than twice a month should sweep annually. Gas insert owners who converted a wood firebox in the 1990s still need an annual inspection, because the venting runs through an original flue that was oversized for wood and is now handling a gas appliance with much cooler exhaust.
That’s the configuration we see constantly in Burien: a gas insert set into an original masonry firebox, venting through a flue lined for a wood fire that’s no longer there. The draft is weak, condensation builds, and creosote that never fully burned off over the years becomes the problem. A sweep addresses the creosote. The inspection tells you whether the liner is right for the appliance.
The tools and the report
After the sweep, we run a camera through the flue and hand you a photo report. You see what we see. If we recommend a repair, the photos are the evidence – not a scare speech. That’s the Garrison Standard: nothing gets recommended without camera proof in your hand.
Gas Fireplace Cleaning in Burien
Gas fireplace cleaning in Burien starts at $149 – $199 for a standard insert service, which includes removing the glass, cleaning the logs and burner, vacuuming the firebox, and checking the venting. Gas fireplaces don’t produce creosote like a wood fire, but they do collect dust, pet hair, and soot film on the logs and glass, and the burners get clogged with debris over time.
What we find in Burien gas inserts
The most common issue is not dust – it’s blocked venting. In Burien’s wet climate, moss and fir needles collect on the chimney cap and around the termination, and a gas insert venting into an oversized original wood flue has weak draft to begin with. The combination means exhaust that should be rising is instead lingering, which is exactly what a carbon monoxide monitor picks up. We see this on gas inserts across the Three Tree Point and Gregory Heights areas every season.
How often a gas insert needs service
Annual is the honest answer. The log set might look fine through the glass, but the burner ports clog, the thermocouple wears, and the venting needs a visual check from the roof. $149 – $199 once a year is cheap compared to a $600 – $1,200 repair when a neglected burner assembly fails mid-winter.
Trusted Brands We Service in Burien
We stock parts for the major chimney brands Burien homes actually have – including Olympia Chimney caps and dampers, Famco termination caps, and Copperfield chimney components. For gas insert burner assemblies and liners, we spec by job, not by margin. That means DuraFlex for relining when a flue is correctly sized for the appliance, HeatShield when a liner needs resurfacing rather than full replacement. Burien customers get the part that works, and we carry what we need locally so we’re not making a second trip across town for a damper plate.
Common Chimney Sweep Problems We See in Burien Homes
- Gas inserts venting into oversized wood flues. The original masonry chimney was built for a raging wood fire with plenty of heat to push draft upward. A gas insert produces far cooler, lazier exhaust, so the flue never warms properly and condensation becomes a chronic problem. Our camera inspection catches this by measuring the liner against the appliance spec.
- Moisture intrusion from moss and debris on the crown. Burien’s wet winters mean moss grows on chimney crowns and flashing, and once water seeps into the mortar joints, the freeze-thaw cycle starts spalling brick. This is not something a brush sweep reveals – it takes an inspection from the roof.
- Animal nests in the smoke chamber. Raccoons and squirrels find Burien’s mature tree canopy and masonry chimneys a perfect combination. A nest on the smoke chamber shelf blocks draft and pushes exhaust into the living space. We remove the nest, sweep the flue, and often recommend a proper cap.
- First-degree creosote that never got addressed. Because so many Burien homeowners burn occasionally – a few weekend fires in fall and winter – creosote builds slowly and often never reaches third-degree glaze. But even first-degree flake blocks draft when compounded with a nest or a partially rusted damper, and that’s where carbon monoxide risk lives.
One recent example: at a split-level rambler near Seahurst Park, our tech pulled a HeatShield-fitted flue liner and found the damper rusted open with a raccoon nest sitting on the smoke chamber shelf. The homeowner burned sporadically, so creosote was only first-degree flake. But the blocked draft was pushing carbon monoxide into the room every time the gas log set ran. We swept the flue, cleared the nest, replaced the damper, and handed the homeowner a photo report showing the clean flue liner and intact chimney cap. Total cost was under $500. The alternative – ignoring it for another season – would have been a venting system that silently failed while the family slept.

FAQs About Chimney Sweep in Burien
Once a year, even with weekend-only burning, is the correct interval for most Burien wood burners. The issue here isn’t just creosote volume – it’s that intermittent burning produces first-degree flake that builds up slowly, and in the meantime, damp Pacific Northwest air and animal activity are doing their own damage. An annual sweep and Level 1 inspection catches the nest on the smoke chamber shelf before it becomes a carbon monoxide problem. If you burn less than twice a month and have the flue inspected annually, we’ll tell you plainly if a sweep can wait another season. Call (830) 251-4560 and we’ll give you a straight answer for your specific fireplace.
Yes, this is the single most common issue we find in Burien’s mid-century housing stock. A gas appliance produces exhaust that’s much cooler and lower-volume than a wood fire, so an original masonry flue sized for wood never warms properly. The result is condensation running down the flue walls, accelerating mortar deterioration, and weak draft that can push exhaust back into the house. The fix varies by flue size and liner condition – sometimes a correctly-sized liner, sometimes a full relining with a product like DuraFlex or HeatShield. The first step is a Level 2 camera inspection so you can see exactly what’s happening. We’ll show you the photos.
First-degree creosote is flaky soot with low combustion risk, second-degree is a tar-like glaze that’s harder to remove, and third-degree is a hard, shiny glaze that often requires chemical treatment or rotary cleaning rather than a standard wire brush. Most Burien homes we sweep have first-degree creosote, because people here burn less than Eastern Washington homes do. But the risk isn’t about degree alone – it’s about what’s blocking the flue alongside it. A modest creosote buildup plus a raccoon nest or rusted-open damper is the real danger combination. Our sweep includes removing creosote at whatever stage it’s in, and the camera report shows you the result. Call (830) 251-4560 for a quote specific to your fireplace.
A standard sweep includes running a properly-sized wire brush through the full flue length, vacuuming the firebox and smoke chamber, and a Level 1 visual inspection of the accessible areas. For Burien homes, we always add a roof-level check of the crown, cap, and flashing, because wet-climate moss and debris are the primary drivers of water intrusion here. You get a written report with photos of anything we find. The price was agreed to before booking, and there is no surprise add-on at the door. That’s the Garrison Standard, and it’s not negotiable.
No, and we say that upfront. A proper sweep takes time, and a rushed job means a dirty flue and a missed crack. Our standard scheduling to Burien is 2 – 4 business days, and we’ll give you a specific arrival window when you book. If you have an active chimney fire, call 911 first, then call us after the fire department clears the scene and we’ll schedule a Level 2 inspection to assess the damage. For everything else, call (830) 251-4560 and we’ll get you on the route.
