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 Company in Seattle, WA
Air duct cleaning in Seattle costs between $450 and $1,200 for a typical single system home, and the job usually takes 3 to 5 hours. What makes Seattle different is damp air and older housing stock: homes here are far more likely to have mold and biological growth inside ductwork than simple dust buildup, especially when those ducts run through vented crawl spaces. If you’re noticing musty smells in a Wallingford bungalow or a Rainier Valley mid-century, the ducts are often the source. Call (980) 447-2498 for a straight answer and a written price before anything starts.
Why Seattle Homes Are Different
Seattle’s marine climate keeps humidity high enough, year-round, that ductwork passing through unencapsulated crawl spaces condenses moisture on the inside of the metal. That condensation feeds mold, mildew, and bacterial growth that simple dust cleaning never touches. In drier cities, duct cleaning is mostly about removing accumulated debris. Here, we’re frequently dealing with biological contamination that requires negative-pressure extraction with HEPA filtration, not just a vacuum pass.
The housing stock compounds the problem. Neighborhoods like Wallingford, Columbia City, and Capitol Hill hold thousands of Craftsman bungalows built before central forced air existed. Those homes had ductwork retrofitted decades later, often with improvised connections that were never sealed properly. The result is a forced-air system pulling crawl space air directly into the living area. In Fremont and Beacon Hill, we regularly open up systems that are 1970s retrofits bolted onto homes originally designed for radiant heat, with gaping duct joints that have been drawing damp, moldy air into the house ever since. And when wildfire smoke settles over the city in late summer, those same leaks pull fine particulate into the ducts, where it stays through the winter heating season.
Our Main Seattle Services
Three jobs account for nearly every call we get in Seattle. Each has its own page with full pricing and detail, but here’s what matters up front.
Air Duct Cleaning in Seattle
This is a full-system cleaning using negative-pressure extraction: a powerful vacuum creates suction at the main trunk while air whips and agitation tools loosen debris from every branch run. In Seattle, we’re typically dealing with mold contamination from crawl space moisture, not just dust. That means the job often includes antimicrobial treatment of the duct interior after cleaning, and it means we spend more time inspecting connections and sealing leaks than a basic clean would require. Homes in West Seattle and the Rainier Valley with original sheet metal ducting through vented crawl spaces often have significant biological growth. See the full breakdown on our Air Duct Cleaning in Seattle page.
Dryer Vent Cleaning in Seattle
Dryer vents clog with lint faster in Seattle than drier climates because humid air makes lint stickier and more likely to mat inside the run. Add the long vertical or offset vent runs common in older Craftsman and mid-century homes, and you have a higher-than-average fire risk with slower drying times. The job involves cleaning the full run from dryer to exterior termination point, checking for kinks and disconnected sections, and clearing the exterior vent hood. For the full procedure and Seattle pricing, see our Dryer Vent Cleaning in Seattle page.
Air Duct Repair in Seattle
Seattle’s retrofitted systems fail at predictable points: unsealed connections, crushed flex runs in crawl spaces, and disconnected boots where floors have settled. Repair means finding every leak and sealing it with mastic or foil tape, replacing damaged sections, and sometimes adding access panels where none existed. It’s common for us to find runs in homes near Green Lake or Beacon Hill that have never been properly connected since the day they were installed. Every repair we do carries a written guarantee. Full scope and repair pricing are on our Air Duct Repair in Seattle page.

In Seattle, the main price drivers are crawl space access difficulty and how much biological contamination is present. A simple dust cleaning in a newer Magnolia home lands on the low end; a mold-heavy system in a 1920s Ballard bungalow with tight crawl space access lands on the high end. Whatever the situation, you get one written price per system before any work begins, and that price does not change at the end of the job.
