Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Dryer Vent Cleaning Across SeaTac
Dryer vent cleaning in SeaTac typically runs $150-$275 for a standard single-family home, and most jobs are scheduled within a few business days. Morton’s Air Duct Cleaning dispatches crews to SeaTac from our Seattle office, so we’re familiar with the airport noise contours, the Port of Seattle retrofit zones, and the mid-century homes that make up most of the local housing stock. If your dryer is taking longer to dry, your laundry room feels humid, or you’ve noticed a musty smell near the vent line, call us at (323) 918-4345 for a free written estimate before any work starts.
We’ve been serving families in the SeaTac area since 2005, and we know the local conditions that affect dryer vents here. The persistent marine humidity, the jet-exhaust particulates that settle on homes near Sea-Tac International Airport, and the patchwork duct systems created by decades of sound-insulation retrofits all create problems you won’t find in drier inland climates. Our Dryer Vent Cleaning team uses Rotobrush and Nikro equipment with HEPA containment, and every visit includes shoe covers, drop cloths, and a photo of the clean-up before we leave.
Why Morton’s Air Duct Cleaning Is SeaTac’s Preferred Dryer Vent Cleaning Company
SeaTac homeowners choose Morton’s because we treat their homes the way we’d want our own treated. Our technicians are background-checked, uniformed, and trained to the Cedarwell C.A.R.E. values, which means quiet tools during nap hours, pet-safe product choices where available, and a written price agreed before anyone touches your vent line.
We’ve built our reputation in SeaTac one visit at a time. Families in the McMicken Heights area, along International Boulevard, and in the neighborhoods near Angle Lake Park have told us the same thing: they want to know what the work costs, what it involves, and that their floors and furniture will be protected. That’s exactly what we deliver. The 365-Day Done Right Promise backs every job, and a live person answers our phone 24/7, not a voicemail tree.
Our crews know SeaTac’s housing patterns. Many homes here were built in the 1950s through 1970s for airport and Boeing workers, then modified under the Port of Seattle’s Residential Sound Insulation Program with new windows and supplemental HVAC components. Those retrofits often left mismatched duct assemblies where aging galvanized metal meets newer flex duct at unsupported junctions. We spot those problems because we see them regularly, and we explain what we find before we quote any additional work.
Dryer Vent Repair in SeaTac
Dryer Vent Repair in SeaTac often involves fixing the damage that marine humidity and decades of lint compaction have caused to mid-century vent lines, especially in homes with Port-retrofit splice points that were never properly supported. When a dryer vent develops gaps, corrosion, or disconnected joints, the moist air meant to exhaust outside leaks into walls, crawlspaces, or the laundry room itself. In SeaTac’s climate, that trapped moisture feeds mildew and can degrade surrounding framing. A typical Dryer Vent Repair in SeaTac runs $200-$450 depending on accessibility and whether we need to replace damaged rigid duct, reroute flex line, or seal junctions at a Port-retrofit splice.
Corroded Vent Lines and Leaking Joints
SeaTac’s salt-laden marine air accelerates corrosion in galvanized steel ductwork, particularly in homes built before 1980. We inspect the full lint pathway with a camera, identify where metal has thinned or separated, and replace damaged sections with proper rigid duct and sealed joints that meet current code.
Port-Retrofit Splice Failures
The sound-insulation program added new supply drops and ERV intakes that were often never sealed to original plenums. We find these unsealed bypasses regularly, and we seal them properly so your dryer vent draws only from the dryer, not from a damp crawlspace gap.
Dryer Vent Cleaning Company in SeaTac
Dryer Vent Cleaning Company work in SeaTac means more than brushing lint from a trap and calling it done. At Morton’s, we perform full-source removal using Rotobrush agitation tools and Nikro negative-pressure HEPA containment, pulling lint and debris out of the vent line rather than pushing it deeper or letting it escape into your home. A standard Dryer Vent Cleaning Company service in SeaTac runs $150-$275 for a single-family home with accessible exterior termination; multi-story runs, bird-guard removal, or significant rerouting may add $75-$150. We provide a written price before we start, every time, with no per-vent add-ons or surprise charges.
Camera Inspection and Full Pathway Cleaning
We run a camera the full length of your vent line to document lint buildup, blockages, and structural problems. In SeaTac homes with Port-retrofit hybrid duct systems, this often reveals compacted lint at unsupported flex-to-metal junctions that other cleaners miss entirely.
What We Do Not Sell
We do not offer fogging “sanitiser” treatments as a standalone fix. Fogging does not remove lint, does not seal duct leaks, and does nothing to stop damp crawlspace air from entering through unsealed ERV gaps. If your vent line has a moisture problem, we fix the source.
Trusted Brands We Service in SeaTac
Morton’s technicians arrive with professional-grade equipment from Rotobrush, Nikro, and Guardsman, not rental-shop vacuums and hand brushes. For SeaTac homes, we stock common vent cap replacements, bird guard assemblies, and rigid duct fittings locally so repairs don’t stretch across multiple visits. The Rotobrush system we use for agitation cleaning combines mechanical brushing with simultaneous negative-pressure extraction, which matters in SeaTac’s older homes where loose lint and microbial debris need containment rather than redistribution. Nikro’s HEPA-filtered collection systems capture particles down to 0.3 microns, including the ultrafine jet-exhaust particulates that accumulate in vents near Sea-Tac International Airport. When we need to seal ductwork or address moisture intrusion, Guardsman products provide the durability we want in this climate.
Common Dryer Vent Cleaning Problems We See in SeaTac Homes
- Compacted lint at Port-retrofit splice points. The flex-to-metal junctions created by sound-insulation retrofits often lack proper support, creating low spots where lint accumulates and moisture pools. We find these blockages with camera inspection, not guesswork.
- Moisture-saturated vent lines from marine humidity. SeaTac’s year-round high relative humidity means lint clumps denser and sticks to duct walls more stubbornly than in drier climates. Our agitation tools break this compaction loose for full removal.
- Unsealed ERV intake gaps pulling damp crawlspace air. The bypass created by poorly sealed retrofit intakes introduces continuous moisture into the vent system. Fogging treats symptoms; we seal the gap and dry the line.
- Corroded exterior vent caps and bird guard failures. Salt air near the airport degrades metal caps faster than inland locations. We replace these with corrosion-resistant assemblies sized for your vent line’s airflow requirements.
Pricing for Dryer Vent Cleaning in SeaTac, WA
Most SeaTac homeowners pay between $150 and $275 for a complete dryer vent cleaning on a standard single-family home with ground-level or single-story exterior access. Dryer Vent Repair in SeaTac typically ranges from $200 to $450, depending on how much damaged duct needs replacement and whether we’re working with accessible crawlspace or wall cavity runs. Bird guard installation runs $85-$150, vent cap replacement $75-$125, and vent rerouting for code compliance or improved airflow $250-$500.
What affects your price: the length and accessibility of your vent run, whether we find damage requiring repair, and whether your home has the Port-retrofit splice points that need additional sealing work. We do not quote per-vent or per-foot pricing that balloons on arrival. You get one flat price per system, agreed in writing, before any work begins. Estimates are free, and we encourage you to compare our written quote to the $79 coupon specials that rarely include camera inspection, HEPA containment, or actual source removal.

FAQs About Dryer Vent Cleaning in SeaTac
SeaTac’s combination of persistent marine humidity and ultrafine jet-exhaust particulates from Sea-Tac International Airport creates denser, stickier lint accumulation than drier inland locations like Tukwila experience. The moisture in the air causes lint to clump and adhere to duct walls, while the additional particulate load gives that lint more material to bind with. If your home also has an unsealed Port-retrofit ERV intake gap, you’re pulling damp crawlspace air directly into the vent pathway, which accelerates compaction further. Call (323) 918-4345 and we’ll camera-inspect to find out exactly what’s happening in your line.
The musty smell usually indicates microbial growth fed by moisture, but fogging does not fix the underlying moisture source and does not remove existing lint or biological material. In SeaTac, the most common moisture source is an unsealed duct junction or ERV intake gap pulling damp crawlspace air into the vent line, a problem left behind by Port of Seattle sound-insulation retrofits in many airport-contour homes. We remove the growth with mechanical agitation and negative-pressure extraction, seal the moisture entry point, and dry the line properly. Fogging without source removal is paying to perfume a problem. Call (323) 918-4345 for an inspection that finds the actual cause.
A genuine cleaning includes camera inspection of the full vent pathway, mechanical agitation with professional tools like Rotobrush systems, simultaneous negative-pressure HEPA containment so debris isn’t redistributed into your home, and a written report of what we found. The $79 specials typically brush visible lint from the trap and first few feet of duct, skip the camera, lack containment, and then upsell fogging or “deep cleaning” once they’re in your home. In SeaTac’s Port-retrofit homes, the coupon special almost always misses the compacted lint at unsealed splice points. We give you one flat price upfront that covers the actual work. Call (323) 918-4345 for a written quote you can compare.
Yes. SeaTac’s high year-round humidity means lint accumulates in denser, more combustible clumps, and the moisture that saturates these clumps can corrode metal ductwork from the inside while supporting microbial growth. A blocked vent also forces your dryer to run hotter and longer, increasing fire risk and energy use. In homes with unsealed Port-retrofit gaps, the additional moisture load makes these problems develop faster than in drier climates. We treat every SeaTac vent cleaning as both a performance and safety inspection. Call (323) 918-4345 to schedule.
Look for flexible duct or additional supply drops that don’t match your home’s original system, especially near the furnace plenum or in crawlspace areas. The retrofit program added ERV intakes and new supply runs that were frequently never sealed to the original galvanized plenum, creating gaps that pull in unfiltered, humid crawlspace air. Our camera inspection identifies these unsealed bypasses in minutes, and we explain what we find with photos before quoting any sealing work. Many SeaTac homeowners don’t realize their dryer vent problem is actually a duct-sealing failure until we show them. Call (323) 918-4345 for a free inspection.
