A standard Level 1 chimney cleaning in SeaTac typically runs $189-$289 and takes about 90 minutes; most appointments are available within 48 hours.

We’ve been driving to SeaTac since 1984. Russell Haines started Hearthstone Chimney Co. that year, and our technicians know the difference between a ranch home off Military Road South and a split-level near Angle Lake. SeaTac isn’t Seattle, and it isn’t Burien. The airport noise mitigation program changed how these houses breathe, and that changes how we clean your chimney.
Why Hearthstone Chimney Co. Is SeaTac’s Preferred Chimney Cleaning & Sweep Company
SeaTac homeowners call us back because we document what we find. Every Chimney Cleaning & Sweep visit ends with photos you can see and a plain-English verdict. No jargon, no scare tactics. We’ve earned a strong local reputation across King County over 42 years, and our SeaTac customers specifically mention the same things: we show up when we say, we explain before we charge, and we leave the hearth cleaner than we found it.
Response time to SeaTac averages under two hours for scheduling, with most routine sweeps booked within 48 hours. Our technicians are background-checked, uniformed, and carry the equipment to complete most jobs in a single visit. That matters in SeaTac, where many homeowners are retired airport or Boeing workers who’ve already dealt with enough contractors who didn’t return calls.
The 90-Day Done Right Promise applies to every SeaTac job. In writing, no arguing. If it’s not right, we come back. That’s the Keystone Standard, and it’s governed by our K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it.
Our Chimney Cleaning & Sweep Services in SeaTac
Level 1 Inspection
A Level 1 inspection is the annual check every SeaTac homeowner with a wood-burning fireplace should schedule. We examine the readily accessible portions of your chimney structure, flue, and appliance connection. In SeaTac’s 1950s ranch homes near the 98158 ZIP code, we often find original clay flue tiles with cracked mortar joints caused by decades of marine moisture cycling. The inspection takes 30-45 minutes and is typically bundled with a standard sweep.

Level 2 Inspection
Level 2 camera inspections are required when you’re buying a home, after a chimney fire, or when you’ve changed your heating appliance. We run a high-resolution camera up the full length of your flue and document every crack, gap, and creosote deposit. In SeaTac’s soundproofed homes, this inspection routinely reveals reversed draft conditions caused by the tight building envelope. You get the photos, you get the plain-English verdict, and you get an upfront price before any repair work begins. Our Chimney Repair in SeaTac team handles anything we find.

Creosote Removal
Creosote builds in three stages, and SeaTac’s cool, damp climate accelerates the worst kind. Glazed creosote, Stage 3, forms when low-intensity smoldering fires meet persistent marine moisture. It’s hard as glass, highly combustible, and cannot be removed with a standard brush. We use professional-grade mechanical whips and, when necessary, chemical modifiers from Copperfield to break the glaze safely. This is not a DIY job. A typical glazed creosote removal in SeaTac runs $340-$520 depending on severity and flue length.

Soot Removal & Fireplace Cleaning
Soot accumulation in the firebox and smoke chamber reduces draft efficiency and stains surrounding masonry. We remove soot from the firebox, smoke shelf, and accessible damper assembly using HEPA-contained vacuums and hand tools. Many SeaTac split-levels have fireplaces that haven’t been professionally cleaned since the Carter administration. The soot we remove is often mixed with decades of ash compaction and animal debris. We also offer Fireplace Services in SeaTac for deeper restoration needs.

Trusted Brands We Service in SeaTac
We stock professional-grade materials from Famco, DuraFlex, and HeatShield on every SeaTac service vehicle. That means no waiting for parts when we find a damaged flue liner or deteriorated chimney crown. Famco caps and dampers resist the moss and moisture that attack SeaTac chimneys year-round. DuraFlex liners handle the thermal stress of corrected draft systems in tight-envelope homes. HeatShield cerfractory flue sealant restores eroded mortar joints without a full rebuild. We don’t use builder-grade substitutes, and we don’t charge you twice because we came unprepared.
Common Chimney Cleaning & Sweep Problems We See in SeaTac Homes
- Reversed draft in soundproofed homes. The Port of Seattle’s noise mitigation program sealed thousands of SeaTac homes tighter than their original design intended. When we open the damper on a service call near the airport corridors, we often see cold smoke or outside air pull visibly backward into the living space. We diagnose combustion-air deficiency before we clean, because sweeping a chimney that cannot draft properly wastes your money.
- Glazed creosote from damp-weather burning. SeaTac’s NOAA station records 38 inches of annual rainfall under persistent marine overcast. Homeowners burning small, cool fires to take the edge off damp evenings create the exact conditions for Stage 3 creosote. It looks like black glass and it will ignite at 451 degrees.
- Moss and moisture erosion on chimney crowns. The same marine layer that keeps SeaTac green keeps chimney crowns saturated. We find heavy moss colonization and spalling concrete on original crowns throughout the eastern residential corridors. Left unchecked, water penetrates the crown and freezes in the masonry below.
- Original masonry fireplaces with no maintenance history. SeaTac’s housing stock of 1950s-1970s ranch and split-level homes was built for airport and industrial workers who often treated fireplaces as decorative. Decades of use without professional sweeping have packed smoke shelves and compromised flue liners. These systems need careful camera inspection before any cleaning begins.
