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 Cottage Lake, WA
Air duct cleaning in Cottage Lake costs between $390 and $1,400 for a whole-home system, depending on the number of vents and the condition of the ductwork. We’re Morton’s Air Duct Cleaning, and we’ve been cleaning ducts in the Pacific Northwest since 2005. Homes here carry more mold spores, fir needles, and crawl-space moisture than almost anywhere else in King County, which means the work takes longer and matters more. Call (323) 918-4345 when you’re ready for a written price before anyone touches a vent.
Why Cottage Lake Homes Are Different
Cottage Lake sits on a freshwater lake ringed by Douglas fir and red alder, and that combination creates a microclimate you won’t find in Redmond or Kirkland. The humidity stays measurably higher year-round, even during dry summer stretches. We see the result inside ductwork constantly: mold colonization that moves faster than it does in drier suburbs, and a compressed mat of fir needles, catkins, and seed debris pulled deep into return-air systems.
Most Cottage Lake homes were built between the 1970s and 1990s on wooded lots with crawl-space foundations. Duct runs frequently pass through those dark, damp, uninsulated spaces, picking up ground moisture and whatever else finds its way under the house. Rodent activity in crawl spaces is common, and that debris ends up circulating through the living-space air supply. Homeowners who change their furnace filter monthly still find a fine layer of organic dust on the registers, because the source is upstream in the crawl space, not in the filter slot.
The tree canopy is part of it too. Heavy fir and alder cover deposits needles onto rooflines and around exterior equipment. On homes with roof-level or exterior-wall intakes, those organics get drawn directly into the return side of the system. Standard filter changes never address it. The work here is different than it is in a drier, treeless subdivision, and the process has to account for that.
Our Main Cottage Lake Services
These are the two jobs Cottage Lake homeowners call us about most. Each has its own detailed page with pricing, step-by-step process notes, and what to expect on the day of the visit.
Air Duct Cleaning in Cottage Lake
Whole-home air duct cleaning here means more than running a vacuum through the registers. We clean the supply and return sides, the trunk lines, and the crawl-space runs where moisture and organic debris accumulate. The fir needle load in Cottage Lake intake systems is consistently heavier than in surrounding areas, so we spend extra time on the return side. Our Rotobrush and Nikro equipment gets the debris out without blowing it into the house. See Air Duct Cleaning in Cottage Lake for full pricing and process details.
Dryer Vent Cleaning in Cottage Lake
Dryer vents in Cottage Lake clog faster than most homeowners expect, largely because the same humidity that grows mold in ducts also causes lint to clump and stick inside the vent instead of blowing through. Long vent runs through crawl spaces and exterior walls are common in these 1970s-to-1990s builds, and each elbow in the run creates a place for wet lint to collect. We clean the full run from dryer to exterior termination and show you what came out. Details and pricing are on the Dryer Vent Cleaning in Cottage Lake page.

What pushes a Cottage Lake quote toward the upper end is usually crawl-space access, heavier-than-typical organic debris in the return side, or a duct run that hasn’t been opened in a decade or more. Every quote is a written price agreed before work starts. No per-vent upsell, no surprise line item on the invoice.

- Shelby Dunham"New house, old dusty ducts. They were gentle in the house, laid down drop cloths, and double checked every register was sealed back up. Air smells fresh now."
- Scott Hemmings"Friendly, calm crew that clearly cared about the house. Covered their shoes, protected the floors, and double checked they'd closed up every vent cover properly. Would have them back."
