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.

AfterAir Duct Cleaning in Seattle, WA
Dryer vent cleaning in Seattle typically costs $129-$229 for a single-family home and takes 60-90 minutes from setup to photo record. What separates Seattle jobs from dryer vent work in drier cities is what our crews actually find inside the vent run: damp lint packed into elbows, rodent nesting material, and in hillside neighborhoods like Queen Anne and Beacon Hill, water that has wicked up through the crawl space into the lower section of the vent. Seattle’s marine humidity means lint never fully dries, so it clings to the duct walls and compacts into layers that a standard vacuum pass cannot remove. Call (806) 606-6902 and we’ll walk through the process and a flat written price before anyone touches a panel.
Why Seattle Homes Are Different
Seattle’s marine climate produces chronically high humidity year-round, not just seasonal spikes, and a large share of the city’s residential stock was built before forced air was standard. Ballard, Fremont, Wallingford, and Capitol Hill are full of pre-1950s craftsman bungalows and 1940s-60s homes originally built with radiant or baseboard heat and no ductwork at all. Forced-air systems were retrofitted later, often routed through tight crawl spaces and unconditioned areas. Those retrofit duct systems are frequently older, poorly sealed, and sized for the original footprint rather than modern HVAC loads.
The consequence is specific: Seattle ductwork lives close to perpetually damp soil. Relative humidity regularly exceeds 80% through the long overcast season, and the roughly 37-38 inches of annual rainfall keeps crawl spaces wet year-round. That means what we pull out of Seattle ducts is not just accumulated dust. It is biological growth, rodent debris, and fungal spores trapped in damp under-house ducts.
The June 2021 heat dome added another layer. A wave of rushed AC retrofits into homes never designed for cooling brought newly installed ductwork that often skipped proper sealing. Those ducts now draw humid crawl-space air into the living envelope, which is why a Seattle duct cleaning that ignores the crawl space often fails within a single rainy season.
Our Main Seattle Services
Seattle homeowners call us most about two services: full air duct cleaning and HVAC system cleaning. Both pull from the same conditions we see across the city, and both end with the same documented photo record.
Air Duct Cleaning in Seattle
Air duct cleaning in Seattle is a biological-growth and moisture-contamination problem more than a dust problem. A typical single-family home in Seattle ranges from $480 to $1,300 depending on square footage and how much bulk debris has accumulated in the runs. Our crews photograph every duct run before and after, so you can see what was actually inside the system, not just what the pressure gauge says. Air Duct Cleaning in Seattle covers the full service in detail.
HVAC Cleaning in Seattle
HVAC cleaning in Seattle usually means cleaning the blower, coils, drain pan, and plenum, not just the ducts. In a city where the heat dome pushed AC units into homes built for baseboard heat, the indoor coil often collects a wet, fibrous mat of Seattle dust that reduces airflow and keeps the blower working harder than it should. HVAC Cleaning in Seattle walks through what that job includes and what it costs.

BeforeAfterDryer Vent Cleaning in Seattle
Dryer vent cleaning in Seattle runs $129-$229 for most single-family homes, and the local problem is damp lint, not dry lint. In a city where 80% humidity is common through the long overcast season, lint never fully dries, so it packs into the vent run and hardens against the walls. On hillside streets in Queen Anne and Capitol Hill, older vent runs that exit through crawl spaces pull in moisture from below, which turns a routine cleaning into a repair call if the duct has started to degrade. Our crews follow the full scope described on our Dryer Vent Cleaning service page, and every job ends with a before-and-after photo record of the full run.
Dryer Vent Inspection
Signs you need it
Clothes take longer than 45 minutes to dry, the dryer exterior gets hot to the touch, or you can smell a musty, burnt-lint odor when the dryer runs.
What it costs in Seattle
A camera inspection in Seattle runs $79-$149 and gets you a written condition report with photos, not just a verbal summary.
How we do it
We run a camera through the full vent run from the dryer connection to the exterior termination, measure the run length and routing, and give you a photo-documented condition report plus a flat written price for any work the photos show.
Vent Cleaning
Signs you need it
The dryer runs a full cycle but towels come out damp, the lint trap fills unusually fast, or a visible cloud of lint blows from the exterior vent while the dryer is on.
What it costs in Seattle
A typical Seattle single-family vent cleaning falls between $129 and $229, depending on run length and the degree of compaction inside the duct.
How we do it
We run a rotating brush and negative-pressure extraction from the dryer connection through the exterior termination, pulling out compacted lint, then photograph the full run before and after.
Lint Removal
Signs you need it
Lint is visible at the exterior vent hood, the dryer shuts off on overheat, or a previous cleaning left visible debris behind the wall.
What it costs in Seattle
Bulk lint removal in Seattle typically costs $129-$229 when part of a standard vent cleaning, though severely packed runs that require disassembly run higher.
How we do it
We clear the full run with a rotating brush, flush the dislodged lint out through negative pressure, and photograph the interior so you can see the duct wall, not a layer of leftover lint.
Bird Guard Installation
Signs you need it
You have heard birds or scratching near the vent, or you can see nesting material protruding from the exterior termination.
What it costs in Seattle
A bird guard install in Seattle generally runs $59-$129 per vent, depending on access and the existing hood condition.
How we do it
We clear any existing nesting material, then install a screened guard over the exterior termination that blocks birds without restricting airflow.
What Dryer Vent Cleaning Costs in Seattle
| Item | Typical range in Seattle |
|---|---|
| Dryer vent inspection | $79-$149 |
| Standard vent cleaning | $129-$229 |
| Bird guard installation | $59-$129 |
How often should a dryer vent be cleaned in Seattle?
Every 12 to 18 months for most Seattle homes, and closer to 12 if the dryer runs daily. The humidity here means lint compacts faster than it does in drier climates. Call (806) 606-6902 for a written price.
Why does my Seattle dryer vent clog faster than my last house?
Seattle’s humidity keeps lint damp and sticky, so it adheres to the duct walls and compacts in layers. Older retrofitted vent runs with extra elbows trap more of it. Call (806) 606-6902 and we’ll photograph the inside.
Duct Repair & Sealing in Seattle
Duct repair and sealing in Seattle is where the city’s retrofit history shows up in hard numbers. Homes built for baseboard heat now run forced-air through duct runs squeezed into crawl spaces and unconditioned areas, and those runs leak. We regularly find 20-30% of conditioned air escaping through gaps, separated joints, and flex duct that has rotted where moisture wicked up through the soil beneath. On a Seattle hillside, a leaking duct pulls humid crawl-space air into the living envelope every time the blower runs. See Duct Repair & Sealing for the full scope of what we do.
Duct Sealing
Signs you need it
Rooms vary in temperature by more than a few degrees, the HVAC runs longer than it used to, or you can feel air moving around the registers when the system is off.
What it costs in Seattle
Aeroseal duct sealing for a typical Seattle home runs $1,500-$3,500, while mastic and tape sealing of accessible joints falls between $300 and $800.
How we do it
We pressure-test the system to find the leak rate, seal the accessible joints with mastic or the full system with Aeroseal, then re-test and photograph the before-and-after pressure readings.
Flex Duct Repair
Signs you need it
You see a collapsed section in the crawl space, a musty or earthy smell comes from the registers, or the system has lost airflow in one part of the house.
What it costs in Seattle
Flex duct repair in Seattle typically costs $200-$600 per section, depending on access and whether the run runs through a tight crawl space.
How we do it
We pull the damaged flex run, size a replacement to match the system’s airflow requirements, reconnect it with proper hangers and sealed joints, and photograph the completed run.
Mastic Sealant
Signs you need it
You can see gaps or cracks around register boots, access panels, or plenum connections in the crawl space or utility closet.
What it costs in Seattle
Mastic sealing of all accessible joints and boots in a Seattle home generally costs $300-$800, depending on how much of the ductwork is reachable.
How we do it
We clean each accessible joint, apply mastic sealant over gaps and boots, then photograph the sealed connections so you can see exactly where the work was done.
What Duct Repair & Sealing Costs in Seattle
| Item | Typical range in Seattle |
|---|---|
| Mastic and tape sealing | $300-$800 |
| Flex duct repair | $200-$600 per section |
| Aeroseal whole-system sealing | $1,500-$3,500 |
Does Seattle weather make duct leaks worse?
Yes. Humid crawl-space air drawn through leaks condenses on cold duct surfaces, which accelerates flex duct degradation and feeds mold growth. A sealed system blocks that exchange. Call (806) 606-6902 for a flat written price.
How do I know the sealing actually worked?
You get a pressure-test reading before and after the job, plus photographs of the sealed joints. The numbers and the photos are part of the standard job record. Call (806) 606-6902.
Air Quality & Sanitizing in Seattle
Air quality and sanitizing work in Seattle starts with what the marine climate leaves behind inside the duct system. We consistently pull duct panels in hillside neighborhoods like Queen Anne and Beacon Hill and find moldy flex duct and saturated sheet metal from below, because the crawl space acts as a year-round humidity chamber. Cleaning alone does not fix that. Sanitizing is a targeted response to what the camera shows: mold on the duct surfaces, bacteria in the condensate pan, or odor compounds embedded in the insulation. See Air Quality & Sanitizing for the full range of what this service covers.
Mold Treatment
Signs you need it
You can see visible mold on duct surfaces, smell a persistent musty odor from the registers, or a home inspection flagged fungal growth inside the system.
What it costs in Seattle
Duct mold treatment in Seattle typically runs $450-$1,200 depending on the square footage of the affected surfaces and how much of the system is reachable.
How we do it
We camera-inspect the full system to map the affected areas, apply an antimicrobial treatment to the interior surfaces, and photograph every treated section before and after.
Bacteria Sanitizing
Signs you need it
The condensate pan has standing water or slime, the system has gone through a flood event, or household members have recurring respiratory irritation the HVAC seems to trigger.
What it costs in Seattle
Bacteria sanitizing for a Seattle HVAC system runs $400-$900, which includes the evaporator coil, drain pan, and plenum.
How we do it
We clean the coil and drain pan, apply a sanitizing agent to the internal surfaces, and photograph the treated components so you can verify the work was actually completed.
UV Light Installation
Signs you need it
Mold or bacteria keep returning after cleaning, or the indoor coil sits in a chronically damp location that cannot be fully dried out.
What it costs in Seattle
UV light installation on a Seattle HVAC system typically costs $800-$2,000 per unit, depending on the coil size and access.
How we do it
We mount the UV lamp in the supply plenum or above the coil, wire it to operate continuously, and photograph the installation and lamp position before leaving.
What Air Quality & Sanitizing Costs in Seattle
| Item | Typical range in Seattle |
|---|---|
| Mold treatment | $450-$1,200 |
| Bacteria sanitizing | $400-$900 |
| UV light installation | $800-$2,000 |
Will sanitizing actually stop mold from returning in my Seattle crawl space?
Sanitizing treats the duct surfaces. If the crawl space still holds standing moisture, mold will come back within a rainy season. We tell you if the crawl space is the root cause. Call (806) 606-6902.
Is the antimicrobial treatment safe for my family and pets?
The products we use are EPA-registered for HVAC use and applied while the system is off, with time to dry before the blower runs. You get the product name in writing before we start. Call (806) 606-6902 for specifics.
