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 Alcott Chimney Sweep Is SeaTac’s Preferred Chimney Inspection Company
We’ve inspected more SeaTac chimneys than we can count, and the ones we remember aren’t the easy ones. They’re the 1958 ranchers off South 154th Street with clay-tile flues that look fine from the roof but tell a different story on camera. They’re the duplexes off Des Moines Memorial Drive that have cycled through three owners and twenty years of deferred maintenance. We know those houses because we work on them every week, and because we’ve built our reputation in SeaTac on showing homeowners exactly what we see before we ask them to spend a dollar.
Ruben Castellano set the standard when he started Alcott in 2002: background-checked, identity-verified technicians announced by name and photo before they arrive. In SeaTac, where a significant share of homes are rentals and many residents are home alone during the day, that matters. You’ll know who’s coming to your door before the truck turns onto your street. Every inspection includes a written price before we start, and every repair carries a written guarantee. If a repair fails within the coverage period, the second visit is free.
Our Chimney Inspection team doesn’t upsell. We run the camera, show you the footage, and tell you plainly when something can wait. That’s a promise we’ve kept in every SeaTac neighborhood we serve, and it’s why homeowners here keep our number.
Level 2 Chimney Inspection in SeaTac
Level 2 Chimney Inspection is the camera-based evaluation SeaTac homeowners need most, especially in the post-WWII brick ranches and duplexes that dominate neighborhoods from Bow Lake to the Airport road corridor. A Level 2 inspection runs a video camera through the flue, examines the crown and cap, checks the damper, and documents the interior condition of the clay tile liner. Hairline cracks, mortar erosion, and separation that are invisible from a rooftop glance show up clearly on camera. That’s why we make the footage part of the conversation, not an afterthought.
Why Level 2 First
After a chimney fire, a lightning strike, or a long stretch with no maintenance, a visual Level 1 look isn’t enough. In SeaTac specifically, the chronic low-frequency vibration from aircraft approaches and departures has produced a pattern we see constantly: clay-tile flue separation in chimneys that appear structurally sound from the outside.
A Level 2 inspection in SeaTac typically runs $299 – $399 depending on access and roof pitch. If you’re buying a home here, most lenders and insurers will require one. If you’ve owned your home for five-plus years and never had the flue scoped, now is the time.
Chimney Leak in SeaTac
A Chimney Leak in SeaTac is rarely just a stain on the ceiling. SeaTac records roughly 38 inches of rain a year, most of it falling between October and April, and a capless or cracked chimney in this environment absorbs that water into the masonry. Rusted dampers, saturated firebox brick, and mortar that spalls during the occasional hard freeze are the downstream effects. We find the entry point with a camera, not a guess.
Where SeaTac Leaks Start
In the 1950s and 60s houses that make up much of SeaTac’s residential core, the leak usually starts at the crown or the absence of a cap. Water pools, saturates the brick, and then the freeze-thaw cycle pushes the face off. The longer it runs, the more repair work follows.
Trusted Brands We Service in SeaTac
When a SeaTac inspection does turn up a liner that needs to be replaced or reinforced, we don’t improvise with box-store substitutes. We install and service professional trade materials including HeatShield resurfacing, Copperfield caps and dampers, and Famco components. These are the brands chimney professionals specify, and we keep common sizes on hand so SeaTac customers aren’t waiting weeks on a parts order. If your chimney needs a product we recommend, we’ll show you exactly what we’re installing and why.
Common Chimney Inspection Problems We See in SeaTac Homes
- Clay-tile flue separation from runway vibration. Homes within a half-mile of the airport corridor show hairline tile cracks and mortar erosion disproportionate to their age. This is a vibration-driven pattern we don’t see at the same rate in Burien or Des Moines, and it means flue separation has to be ruled out with a camera on every SeaTac inspection.
- Capless chimneys that have been taking rain for decades. A damper rusted open and firebox masonry saturated with standing water are common in SeaTac’s un-capped 1950s stock. The damage isn’t visible without a camera run, and it often gets discovered during a leak investigation.
- Deferred maintenance across rental transitions. Many SeaTac homes have cycled through multiple owners and tenants, meaning chimney upkeep has been skipped for years at a time. We often find original clay tile liners with no caps and no record of ever being swept or inspected.
- Upsold relining jobs based on a rooftop glance. We see the repair quotes SeaTac homeowners have been handed by other companies, and too often the recommendation is for a full reline that no one ever proved with footage. Our policy is simple: nothing gets recommended without camera evidence you can see for yourself.
Pricing for Chimney Inspection in SeaTac, WA
A Level 1 visual inspection in SeaTac runs $149 – $199 and is appropriate for a chimney that’s been recently maintained and shows no exterior issues. A Level 2 camera inspection covers the flue interior, crown, cap, damper, and smoke chamber, and runs $299 – $399 for most SeaTac homes. If you need a Level 3 inspection because a chimney fire or structural failure is suspected, we’ll quote that scope after explaining why it’s necessary. What affects cost most is roof pitch and access: some SeaTac ranches have walkable low-slope roofs, while steeper homes on hill lots take more setup. The price we quote is the price you pay, and every repair comes with a written guarantee. Call (336) 863-3889 for a free estimate on your SeaTac chimney.

FAQs About Chimney Inspection in SeaTac
You can expect a Level 2 camera inspection as the right starting point. That means we run a camera up the full length of the flue, check the crown, cap, damper, and smoke chamber, and then walk you through what we found, frame by frame. For a 1960s SeaTac home with no inspection history, the camera is non-negotiable. Clay-tile liners from that era crack and separate, especially under decades of runway vibration, and the damage simply won’t be visible from the roof. Give us a call at (336) 863-3889 and we’ll talk you through exactly what the inspection will include before you book.
Yes, it does, and we see the evidence in SeaTac more than anywhere else in the metro. The constant low-frequency vibration from aircraft approaches and departures accelerates mortar joint cracking and hairline flue tile separation, especially in the 1950s and 60s masonry chimneys that dominate the residential core near SR 518 and International Boulevard. It’s the same reason homeowners here notice more hairline cracks in interior plaster and foundation brick than homeowners in Burien or Des Moines see. For SeaTac, we treat vibration-induced flue separation as a baseline assumption on every inspection, not an occasional finding. If you’re near the corridor, a camera run is the only way to know what’s actually happening inside your flue.
It’s probably worse than it looks from the outside. Thirty seasons of SeaTac rain draining into an uncapped flue means the damper is likely rusted open or seized, the firebox masonry is saturated, and the next hard freeze is what spalls the brick face. The standing water also works on the clay tile liner, accelerating spalling and creating a path for carbon monoxide into the home. The fix starts with a proper inspection, because we won’t recommend a repair scope until we’ve seen the interior on camera. Once we know what we’re looking at, we’ll give you a written price before any work starts. Call (336) 863-3889 for a free estimate.
Ask for the footage. If a company recommends a full reline, they should be able to show you the interior video that proves it. In SeaTac, where the housing stock is older and mortar-joint erosion in the smoke chamber is common, the upsell pattern we see repeatedly is a company quoting a full reline off a rooftop glance with zero camera evidence. Our policy is different: nothing gets recommended that you haven’t seen with your own eyes. If the flue is sound enough to wait, we’ll say that plainly and tell you when to recheck it. That’s the whole reason we put the camera in our service and the footage in your hands.
Yes, you do, and the reason has nothing to do with firewood. SeaTac homes often use the chimney as the vent path for the furnace or water heater, and a hairline crack in a clay tile liner that opens under vibration can leak carbon monoxide into the house. If the chimney is entirely unused, it’s still taking on decades of water damage if the crown is cracked or there’s no cap, and that water is working on the brick and the structure around it. A camera inspection tells you whether the flue is safe to vent through, whether it’s leaking, and what, if anything, actually needs attention. Call (336) 863-3889 and we’ll get you scheduled.
If you own a SeaTac home, the responsible move is to know what’s inside your flue before it becomes a problem.
