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.

If your chimney is smoking back into the room, shedding brick faces, or leaking around the flashing, call us at (253) 323-5667. We’ll book a Level 2 inspection with camera, put a written price in your hand before anyone picks up a trowel, and back the work with our 365-Day Done Right Promise.
Why Emberly Chimney Cleaners Puyallup Is SeaTac’s Preferred Chimney Repair Company
We’ve inspected thousands of chimneys in King County since 2009, and SeaTac’s housing stock keeps us busy in ways no neighboring city replicates. The Port of Seattle’s Sound Insulation Program retrofitted hundreds of homes here with tight air sealing that never accounted for combustion air, so our Chimney Repair team sees backdrafting and glazed creosote concentrated along the flight corridors in a pattern we simply don’t find in Puyallup or Sumner.
Our reviews from SeaTac customers consistently mention the same thing: the technician showed them the camera footage, explained what was actually broken, and handed them a written scope and price before asking for a decision. No surprise charges. No pressure to commit while someone’s standing in their living room.
When you call (253) 323-5667, a live person answers. We assign a named, background-checked technician, text you when they’re en route, and arrive uniformed with license information visible. Dispatch and scheduling are coordinated from our Seattle office, but the crew that shows up knows SeaTac’s 50- to 70-year-old masonry stacks and the specific failure modes this climate and housing age produce.
Our Chimney Repair Services in SeaTac
Mortar Repointing
SeaTac’s original masonry chimneys were built with lime-based mortar that has absorbed decades of Pacific Northwest rain. We grind out deteriorated joints to proper depth and repoint with mortar matched to the original composition and the local freeze-thaw cycle. A typical mortar repointing job on a SeaTac chimney runs $450-$1,200. We document the joint depth and bond with photos before and after, under Haven Standard Clause 4.
Spalling Brick Repair
Spalling - when brick faces flake or pop off due to moisture trapped inside the masonry - is everywhere in SeaTac’s older neighborhoods. The marine climate keeps bricks perpetually damp, and infrequent cold snaps trigger freeze-thaw damage that accelerates through winter. We remove spalled units, source matching brick through our Haven buying network, and rebuild the affected courses. Spalling brick repair in SeaTac typically costs $650-$1,800 depending on how many courses are involved. Every repair is photographed and included in your documented record.
Chimney Waterproofing
Waterproofing a SeaTac chimney isn’t optional maintenance; it’s structural protection. Moss colonization on crowns and water working into mortar joints will destroy a stack faster than creosote ever could. We apply vapor-permeable sealers formulated for marine climates, never trapping moisture inside the masonry. Chimney waterproofing in SeaTac runs $300-$750 for a standard application. We specify the product by name - often from Olympia Chimney or Famco - and show you the coverage area on camera before we start.
Flashing Repair
Failed chimney flashing is the single most common leak source we find in SeaTac’s 1960s and 1970s housing stock. Original step flashing has corroded, or the counterflashing has separated from the brick, or the sealant has hardened and cracked after twenty Pacific Northwest winters. We remove the old flashing, inspect the deck and surround for rot, and install new copper or galvanized flashing with proper overlap and seal. Flashing repair in SeaTac typically runs $400-$950. We photo-document the underlying condition so you see why replacement was necessary, not just told.

AfterTrusted Brands We Service in SeaTac
We source repair materials through Haven’s buying network specifically to keep customer prices honest. For SeaTac jobs, we regularly stock Gelco chimney caps, Olympia Chimney liner components, and Famco flashing and sealant products. This means most repairs don’t wait on special orders. When we installed that HeatShield flue liner on the 1962 ranch off South 176th Street, the liner kit was already on our truck. We don’t markup materials mysteriously; the written price lists every component by name and source.
Common Chimney Repair Problems We See in SeaTac Homes
- Backdrafting after SIP weatherization. The Port of Seattle’s Sound Insulation Program sealed hundreds of SeaTac homes without adding combustion air. Fireplaces now smolder, smoke rolls into the room, and flues that look lightly used harbor dangerous glazed creosote. We test draft and inspect the flue with camera before recommending any solution.
- Spalling brick and failed mortar from decades of rain. SeaTac’s 50- to 70-year-old chimneys have absorbed moisture through porous crowns and deteriorated mortar joints. The damage shows up during routine cleaning calls as brick faces that crumble to the touch and mortar that powders out between courses.
- Glazed creosote in “barely used” flues. Damp alder and fir, common in western Washington, plus the SIP-induced draft starvation, produce third-degree creosote that hardens to a tar-like glaze. It looks like light use from the hearth side; the camera reveals a flue lined with fuel for a chimney fire.
- Moss-cracked crowns and freeze-thaw mortar damage. SeaTac’s year-round moisture lets moss colonize chimney crowns, and infrequent cold snaps crack the mortar underneath. Water then enters through hairline fractures that widen each winter. Brushing won’t fix this; the crown needs repair or rebuild.
Pricing for Chimney Repair in SeaTac, WA
We put real numbers on the page because Haven Standard Clause 1 requires a written price before any work starts. Here’s what chimney repair costs in SeaTac’s market:
| Service | Typical Range in SeaTac |
|---|---|
| Mortar repointing (partial chimney) | $450 - $1,200 |
| Spalling brick repair (per course/section) | $650 - $1,800 |
| Chimney waterproofing | $300 - $750 |
| Flashing repair | $400 - $950 |
| Chimney crown repair or rebuild | $800 - $2,200 |
| Partial chimney rebuild (above roofline) | $1,500 - $2,800 |
Three factors move SeaTac jobs within these ranges: accessibility (steep roof pitch or tight clearance), the extent of hidden damage found during camera inspection, and whether the chimney has been modified by prior SIP work that now complicates venting. We don’t “discover” extra costs after starting. The camera shows everything before we price anything. Call (253) 323-5667 for a free estimate - we’ll inspect, document, and quote in writing with no obligation.

FAQs - Chimney Repair in SeaTac
The SIP weatherization sealed your home’s envelope without adding combustion air, so your fireplace now competes with exhaust fans, dryers, and HVAC systems for the same limited air supply. The fire smolders, draft reverses under negative pressure, and smoke spills into the room. We test draft pressure and inspect the flue with camera to determine whether the fix is a dedicated combustion-air duct, a properly sized liner, or both. Call (253) 323-5667 and we’ll diagnose it with documentation you can see.
Draft-starved fires burn cooler and slower, which produces third-degree creosote even with light use. The glazed, tar-like deposit doesn’t look like normal soot; it hardens to the flue wall and can fuel a chimney fire at temperatures above 1,000°F. We see this pattern concentrated in SIP-retrofitted SeaTac homes along the airport noise corridors, where the tight envelope turns every fire into a creosote factory. The camera shows the difference between light use and dangerous glazing - we’ll walk you through the footage before recommending cleaning or repair.
Most SeaTac chimneys date from the 1950s through 1970s, built during the airport’s rapid expansion. At 50 to 70 years old, these stacks have original lime mortar that’s deteriorated, clay-tile flues that may be unlined or cracked, and crowns that were never designed to shed Pacific Northwest rainfall. Age alone doesn’t condemn a chimney, but it means we frequently find multiple failure modes - spalling brick, failed flashing, and deteriorated crowns - on the same inspection. The camera shows which repairs are urgent, which can be scheduled, and which conditions are stable enough to monitor.
NFPA 211 recommends annual inspection of all chimneys, vents, and solid-fuel-burning appliances, regardless of use. In SeaTac, this matters even for “decorative” fireplaces because moisture intrusion, seismic settling, and animal intrusion can damage an unused flue. We’ve found blocked flues, deteriorated liners, and water-damaged structures in chimneys the homeowner hadn’t lit in years. The inspection is visual and camera-based; if the system is sound, the documentation proves it for insurance or resale purposes.
Haven Standard Clause 4 requires a documented photo record on every job, and Clause 1 requires a written price before work starts. We don’t recommend liners - or any repair - without camera evidence you can see for yourself. On that 1962 ranch off South 176th Street, we showed the homeowner the same camera footage we saw: glazed creosote, failed mortar, and an unlined clay flue starved of draft. The HeatShield liner was sized and priced in writing before installation.
