We’re Landmark Air Duct Cleaning, and we’ve spent 11 years clearing, rerouting, and protecting dryer vents across Seattle’s distinct neighborhoods — from the salt-weathered craftsman bungalows of Ballard to the mid-century ramblers on Mercer Island. Seattle’s marine climate isn’t gentle on metal. The salt-laden air blowing off Puget Sound accelerates corrosion on dryer vent hardware years faster than what you’d see in Spokane or Yakima. Our Dryer Vent Cleaning team knows the local failure patterns because we’ve handled them personally — owner-led on every job, with Richard Anderson running the equipment himself.
Whether you’re in Wallingford, Queen Anne, or Capitol Hill, we carry the parts to fix salt-damaged systems on the spot. No waiting for hardware orders. No sending a salesperson who can’t touch a tool.
Why Landmark Air Duct Cleaning Service Washington Is Seattle’s Preferred Dryer Vent Cleaning Company
732 customers and counting have left verified reviews averaging 4.9 stars — that volume paired with that rating tells you something about repeatability. In Seattle’s home service market, where crews rotate and accountability gets diffused through dispatch centers, Richard Anderson’s model is deliberately different: he’s Owner and Lead Technician, meaning the person who quotes your job runs the Rotobrush and signs off on the final airflow test.
We’ve responded to dryer vent emergencies from White Center to Boulevard Park within hours, not days. Seattle’s housing stock demands this responsiveness — a corroded exterior vent cap during a rainy October weekend can back lint into a system fast, and the humidity keeps that lint paste-like and stubborn. Our Nikro vacuum systems and Rotobrush agitation tools are the same units restoration contractors use after water damage, not rental-grade equipment that leaves residue behind.
Property managers in Capitol Hill and Ballard call us because we document before-and-after airflow readings. Homeowners call us because Richard explains what he found in plain terms — no upsell theater, just what failed, why it failed, and what prevents it from failing again.
Our Dryer Vent Cleaning Services in Seattle
Dryer Vent Inspection
Every Seattle job starts with a full vent run inspection using a borescope camera. In neighborhoods like Ballard and Wallingford, we’re checking for three local-specific issues: salt-air corrosion on metal duct sections, sagging flex-duct low points from humid crawl spaces, and — in homes with 1920s–1940s retrofits — whether an old gravity-furnace plenum is creating dead-air zones that trap lint. We measure airflow velocity at the exterior cap and check backpressure at the dryer connection. You’ll see what we see. The inspection itself runs $85–$125, waived if you proceed with cleaning.
Vent Cleaning & Lint Removal
Our standard cleaning for Seattle homes runs $150–$225 and includes full lint removal from the dryer connection through the exterior cap. We use Rotobrush mechanical agitation plus Nikro HEPA vacuum extraction — critical in Seattle’s humidity, where lint clumps with moisture and won’t move with air alone. For longer vent runs common in Queen Anne hillside homes or multi-story Capitol Hill townhouses, expect $225–$325. We clean until the borescope shows bare duct wall and airflow readings hit manufacturer spec.
Vent Rerouting
Seattle’s older homes often have dryer vents routed through crawl spaces that flood seasonally or through exterior walls with compromised flashing. Rerouting is our most-requested specialty service here — $350–$650 depending on run length and access. We reroute through interior walls when possible, using smooth-wall rigid ducting with sealed joints, avoiding the flex-duct sag points that plague humid crawl spaces. In Wallingford, we’ve rerouted vents out of chronically damp pier-and-beam crawl spaces into conditioned attic space, eliminating the moisture-lint blockage cycle entirely.
Bird Guard Installation & Vent Cap Replacement
Seattle’s coastal salt air destroys standard vent caps. The flapper springs corrode. The hinges seize. Lint backs up. We replace failed caps with stainless steel or UV-resistant polymer units — $125–$225 installed — and add Guardsman bird guards where starlings or sparrows have nested. In Ballard, we serviced a 1920s craftsman where the original gravity-furnace plenum had been left intact during a forced-air retrofit, creating a dead-air chamber that trapped decades of lint. Our Rotobrush cleaned the blocked dryer vent, and we replaced the corroded exterior vent cap with a Guardsman bird guard and stainless steel cap to resist salt air. Bird guard installation alone runs $85–$150.

Trusted Brands We Service in Seattle
We run professional-grade Rotobrush and Nikro cleaning systems — the same equipment categories used by commercial restoration contractors, not rental-store alternatives. For replacement components in Seattle’s corrosive environment, we stock Guardsman bird guards and stainless vent caps rated for marine exposure, plus Abatement Technologies HEPA filtration for post-cleaning air scrubbing when needed. We carry these parts on our Seattle service vehicles, so most cap replacements and guard installations happen same-day without ordering delays.
Common Dryer Vent Cleaning Problems We See in Seattle Homes
- Salt air rusts metal vent ducts from the outside in. In Seattle’s coastal neighborhoods — Ballard, Magnolia, Alki — we’ve pulled vent sections with pinhole corrosion that trapped lint against the duct wall, restricting airflow months faster than you’d see in Spokane’s dry climate. The rust isn’t always visible from the interior until we camera it.
- Exterior vent caps seize from corrosion. The flapper mechanism on standard galvanized caps fails predictably in Seattle’s salt air. When the flapper can’t open, exhaust pressure forces lint backward into the vent run. We find this on roughly one in three Seattle homes over 15 years old.
- Flexible aluminum ducts degrade in humid crawl spaces. Seattle’s persistent crawl space humidity — October through May, often year-round — causes flex-duct to sag between supports. Low points collect lint and moisture into dense blockages that rigid ducting wouldn’t create. We see this constantly in pre-war craftsman homes with pier-and-beam foundations.
- Wildfire smoke season drives secondary blockages. Seattle’s August–September smoke events (Eastern Washington and Oregon fires since 2017) force homeowners to keep windows sealed and dryers running longer. Fine particulate matter infiltrates homes and compounds lint accumulation, creating a predictable annual spike in vent restriction calls each September.

What moves you within these ranges? Run length, access difficulty, and whether we’re dealing with corrosion-damaged hardware that needs replacement versus simple cleaning. Homes in Ballard and Wallingford with original 1920s construction often require more time — tight crawl spaces, abandoned plenum boxes, retrofit ductwork that doesn’t meet modern codes. We quote upfront after inspection, not after we’ve started. Call (877) 335-1974 for an exact figure — estimates are free, and Richard Anderson handles the assessment personally.

FAQs — Dryer Vent Cleaning in Seattle
Seattle’s salt-laden coastal air accelerates corrosion on metal dryer vent ducts and exterior caps by several years compared to Spokane’s dry inland climate. We regularly find pinhole rust in Seattle vent walls that trap lint into restricted airflow patterns rarely seen east of the Cascades — the salt attacks from the outside in, where you can’t see it without a camera. Our fix: stainless steel or marine-rated polymer replacements, not standard galvanized hardware. Call (877) 335-1974 for an inspection — we’ll show you exactly what your vent material is and what condition it’s in.
It can. In Ballard and Wallingford, we regularly find that the original gravity-furnace plenum box was never removed when forced-air ductwork was retrofitted — leaving a sealed dead-air chamber that the new system’s airflow never touches. If your dryer vent was routed near or through this zone, lint and moisture can migrate into the plenum cavity, creating a reservoir that contaminates surrounding air pathways. We camera-inspect for this condition specifically in pre-1940s Seattle homes. Call (877) 335-1974 — Richard Anderson will check your specific layout.
Schedule your cleaning in July or early August, before Seattle’s recurring wildfire smoke season peaks. Since 2017, smoke from Eastern Washington and Oregon fires has created a predictable late-summer demand spike — homeowners seal windows, run dryers more, and discover their vents were already partially blocked. Cleaning before smoke arrives ensures your exhaust system isn’t adding backpressure to an already stressed indoor environment. Call (877) 335-1974 to book ahead of the August rush.
Yes — if your vent run uses flexible aluminum or thin galvanized metal, we typically recommend upgrading to smooth-wall rigid ducting with sealed joints, especially for portions exposed to crawl space humidity or exterior salt air. For the terminal cap, stainless steel or high-grade polymer outlasts galvanized by years in Seattle’s marine environment. We don’t recommend plastic flex-duct at all — it sags and collects lint in humid conditions. Richard Anderson evaluates each home’s specific exposure during inspection. Call (877) 335-1974 for material recommendations tailored to your vent run.
The combination of salt air, persistent moisture, and temperature cycling causes standard vent cap flappers and springs to corrode and seize faster here than in drier climates. A seized flapper can’t open under dryer exhaust pressure, forcing lint backward into the vent run and creating a fire hazard. We replace failed caps with marine-grade stainless or UV-resistant polymer units rated for coastal exposure — the upgrade typically pays for itself in avoided service calls. Call (877) 335-1974 if your cap hasn’t been checked in two years; we’ll test the flapper operation and airflow under load.
