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.

SeaTac’s mid-century housing stock and the Port of Seattle’s Sound Insulation Program create chimney problems you won’t find in newer suburbs. The 1950s-1970s tract homes near the airport corridor still carry original masonry chimneys with mortar joints that have soaked up four decades of Pacific Northwest rain. When the Port retrofitted those homes with airtight windows and doors for FAA noise mitigation, they sealed the envelope without adding combustion air - so fireplaces that once drafted fine now starve for makeup air and backdraft smoke into living rooms. That’s why our SeaTac sweeps include damper evaluation and combustion-air assessment as standard, not extras.
Why SeaTac Homes Are Different
SeaTac hosts the official regional weather station, and the data tells the story: 38 inches of annual rainfall, persistent marine overcast, and cool, damp winters that keep masonry wet nine months of the year. That moisture accelerates mortar spalling and crown deterioration in exposed chimneys year-round, not just in freeze-thaw cycles.
The housing stock compounds the problem. The residential core was built in three waves - 1950s airport-worker tracts, 1960s expansion near Angle Lake, and 1970s infill - and a high percentage function as long-term rentals with deferred maintenance. We regularly pull multiple seasons of Class II and III creosote from flues that haven’t seen a sweep in five or ten years. The low, smoldering fires SeaTac residents burn to take the damp chill off compound the buildup.
Then there’s the Sound Insulation Program. We’ve lost count of the clean-looking flues that still reek of smoke intrusion - the signature of a retrofit home with negative pressure and no makeup air. The fix isn’t more cleaning; it’s assessing the whole system. That’s the difference between a sweep and a proper SeaTac chimney evaluation.

AfterChimney Cap & Crown in SeaTac
SeaTac’s exposed masonry chimneys take a beating from 38 inches of annual rain and persistent marine overcast. The original concrete crowns on 1950s-1970s homes have cracked, slumped, or spalled entirely, and the galvanized caps installed decades ago have rusted through. We install Chimney Cap & Crown systems with materials from Gelco and Olympia Chimney, sized to the flue count and roof pitch of each SeaTac home.
Crown Repair
Signs you need it
Visible cracks in the concrete crown top, pieces of mortar collecting at the chimney base, or water staining on the ceiling near the fireplace in SeaTac homes.
What it costs in SeaTac
Crown repair in SeaTac typically runs $450-$850 depending on crack extent and whether the wash needs full rebuilding.
How we do it
We grind out cracked concrete, apply a bonding agent, and pour new crown mix with proper slope and drip edge, then document with before-and-after photos under Haven Standard Clause 4.
Cap Replacement
Signs you need it
Rust streaks down the chimney face, missing mesh sides, or a cap that rattles loose in SeaTac’s winter windstorms.
What it costs in SeaTac
Single-flue cap replacement in SeaTac ranges $180-$340 installed; multi-flue caps run $320-$580.
How we do it
We measure the flue and chimney top, fabricate or order the correct cap from Olympia Chimney or Gelco, and secure it with stainless steel fasteners rated for marine exposure.
What Chimney Cap & Crown Costs in SeaTac
| Item | Typical range in SeaTac |
|---|---|
| Crown repair | $450 - $850 |
| Single-flue cap replacement | $180 - $340 |
| Multi-flue cap installation | $320 - $580 |
Can a cracked crown wait until next year?
Not safely in SeaTac. Once water penetrates crown cracks, freeze-thaw and marine moisture accelerate spalling and can destroy the chimney top within two winters. Call (253) 447-5982 for a free camera evaluation - estimates are free.
Why does my cap keep blowing off?
SeaTac’s winter windstorms expose poorly secured caps. We use marine-grade stainless fasteners and proper fit to flue dimensions, not universal clamp styles. Call (253) 447-5982 - we’ll measure and quote in writing.
Chimney Liner & Rebuild in SeaTac
SeaTac’s original clay flue liners from the 1950s-1970s have survived decades of Pacific Northwest moisture and heavy creosote loads, but they’re failing now in clusters. We see cracked terracotta, shifted tiles, and liners that never met modern sizing requirements for today’s heating appliances. Our Chimney Liner & Rebuild work starts with a camera scan to document damage before recommending any solution.
Stainless Steel Liner
Signs you need it
Cracked clay tiles visible on camera scan, pieces of terracotta in the firebox, or a water heater or furnace venting into an unlined chimney in older SeaTac homes.
What it costs in SeaTac
Stainless steel liner installation in SeaTac ranges $2,800-$4,500 for a typical single-flue application.
How we do it
We measure the flue with video verification, order 316Ti stainless from DuraFlex or HeatShield, and install with proper top and bottom connections and insulation per manufacturer spec.
Partial Rebuild
Signs you need it
Spalling brick above the roofline, a leaning chimney stack, or mortar joints that crumble to the touch - common in SeaTac’s rain-soaked mid-century masonry.
What it costs in SeaTac
Partial chimney rebuild in SeaTac typically runs $3,200-$6,800 depending on height and accessibility.
How we do it
We dismantle to sound masonry, salvage reusable brick where possible, rebuild with matching mortar, and install a new crown and cap before documenting everything under Haven Standard Clause 4.
What Chimney Liner & Rebuild Costs in SeaTac
| Item | Typical range in SeaTac |
|---|---|
| Stainless steel liner | $2,800 - $4,500 |
| Partial rebuild | $3,200 - $6,800 |
| Full chimney rebuild | $8,500 - $15,000 |
Do I really need a new liner, or can you patch the old one?
Clay tile liners cannot be patched to code compliance. If the camera shows cracks, gaps, or missing tiles, NFPA 211 requires liner replacement for safe operation. Call (253) 447-5982 - we’ll show you the footage and quote in writing.
How long does a stainless liner last?
Properly installed 316Ti stainless steel liners carry a lifetime warranty and typically outlast the appliance they’re venting. Our installs use DuraFlex and HeatShield materials with proper insulation. Call (253) 447-5982 for specifics on your flue.

FAQs About Chimney Cleaning in SeaTac
Most chimney cleaning and cap replacement does not require a permit in SeaTac. Crown rebuilds, liner installations, and structural rebuilds typically do, and we handle permit submission as part of the written scope. We’ll tell you before work starts whether your job triggers permitting.
Standard sweeps in SeaTac usually book within 5-7 days during fall and winter peak season, sometimes sooner in spring and summer. Emergency calls for blocked flues or suspected chimney fires get priority same-day response when possible. Call (253) 447-5982 to check current availability.
Yes. The airtight retrofit often creates negative pressure that causes backdrafting, smoke odor, and poor draft even with a clean flue. We assess combustion air and damper function as standard in these homes, not as an upsell. The camera inspection will show whether the problem is the chimney or the building envelope.

What SeaTac Customers Say
"We were buying the house and needed a real inspection. The report had photographs, the standard it was done to, and a clear repair figure. The seller paid for the repair."
- Lorna D."They told me the flue was fine and I did not need a liner. Charged me for the inspection and nothing else. That is why I have called them twice since."
- Hal M."They ran a camera down the flue and showed me the cracked tiles on a screen. The previous company had swept it twice and never mentioned it."
