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 Des Moines, WA
Air duct cleaning in Des Moines, WA typically runs $350 – $650 for a whole-home system and is best scheduled before the marine layer thickens in late fall. The combination of Puget Sound humidity, Sea-Tac jet exhaust particulate, and aging post-war ductwork makes this a distinct market from drier inland suburbs. At Hollis Air Duct Cleaning, we price every Des Moines job in writing before we start, backed by our 365-Day Done Right Promise. Call us at (361) 326-5060 for a free estimate.
Why Des Moines Homes Are Different
Des Moines sits on the eastern shore of Puget Sound, directly beneath the Sea-Tac flight path, and that geography changes what we find inside local ducts. The marine layer rolls in heavy for eight months of the year, keeping humidity high enough that condensation collects in crawlspace-mounted systems, especially in the 1950s-70s ranches that dominate the housing stock. We’ve opened registers in the Woodmont and Redondo Beach areas to find a fine, greasy black film that wipes off as soot, not ordinary household dust. That’s jet exhaust particulate, unique to this corridor.
Most Des Moines homes are single-story ranches or split-levels with short duct runs, which sounds simple until you factor in the original galvanized steel or early flex duct still in place. Crawlspace systems pull in damp air year-round, and winter wind-driven rain forces water through foundation vents. Summer wildfire smoke gets drawn into fresh-air intakes. These conditions mean a Des Moines duct cleaning isn’t just debris removal; it’s moisture and particulate mitigation specific to this shoreline position.
Our Main Des Moines Services
Des Moines homeowners call us most often for three jobs shaped by local conditions. Each service has its own page with full details.
Air Duct Cleaning in Des Moines
We clean the full supply and return system with Rotobrush rotary brush equipment and Nikro negative-air machines, pulling debris through the trunk lines rather than pushing it into the house. In Des Moines, we pay special attention to mold and mildew in crawlspace-mounted systems and the black particulate buildup that registers collect from overhead flight traffic. Every job gets a written price before we start and before-and-after photos of your own ducts. Air Duct Cleaning in Des Moines
Dryer Vent Cleaning in Des Moines
Dryer vent blockages are a fire hazard, and Des Moines’s humid climate means lint clumps denser and sticks to flex-duct walls longer. We run a rotary brush through the full vent line to the exterior cap, then verify airflow with a meter. Most Des Moines jobs take 45 – 90 minutes, and we check whether your vent terminates through the roof, wall, or crawlspace, common in local ranches. Dryer Vent Cleaning in Des Moines
Duct Sealing in Des Moines
Leaky ducts in Des Moines pull humid crawlspace air and jet exhaust particulate directly into your living space. We seal joints and seams with mastic and metal-backed tape, then pressure-test the system to verify the seal holds. This matters especially in homes with original galvanized trunk lines where seams have worked loose over sixty years. Duct Sealing in Des Moines
