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.
Air Duct Cleaning Company in Washougal, WA
Air duct cleaning in Washougal runs $350 – $650 for most single-system homes, with dryer vent cleaning at $120 – $220 and duct sealing at $400 – $800 depending on accessibility. We’re Hollis Air Duct Cleaning, and our crews work Washougal jobs differently than Vancouver or Portland calls because the Columbia River Gorge throws a dust load at this city that doesn’t exist two miles west. Our phone is (361) 326-5060 if you want a written quote before anyone steps into your home.
Why Washougal Homes Are Different
Washougal sits in the Columbia River Gorge, where near-constant east winds funnel fine silt and volcanic ash from the eastern Columbia Basin into homes. That gorge-blown particulate isn’t normal household dust, and it doesn’t let up. Our technicians regularly pull gray-brown volcanic grit out of cold-air returns on the west-facing walls of hilltop homes, a signature of wind intrusion that Vancouver crews rarely see.
The same gorge wind drives extreme temperature swings. Hot, dry east winds in summer and ice-storm cold in winter force HVAC systems to cycle hard, pulling that grit deep into ductwork. Wildfire smoke events push through from the east while the rest of the metro stays clearer, and the wet maritime season drives moisture and pollen through systems. Demand here swings with gorge wind and smoke, not just spring allergies.
Housing stock splits two ways: older mill-era homes near downtown and the river, many with retrofitted or undersized duct systems, and large newer subdivisions up the hill along the SR-14 corridor with builder-grade flex duct that collects dust quickly and kinks or tears at fittings. Each type presents different access challenges and different contamination patterns.
Our Main Washougal Services
Most Washougal homeowners call us for one of three jobs. Each has its own page with full detail on what we do, what it costs, and how we handle the local conditions.
Air Duct Cleaning in Washougal
We clean supply and return ductwork with Rotobrush rotary brush systems and Nikro negative-air machines, pulling out the volcanic silt and ash that gorge winds deposit in Washougal homes. The job includes vent covers, main trunk lines, and the plenum. In older mill homes near downtown, we often find retrofitted ducts with tight access; in hilltop subdivisions, we address flex-duct kinks that trap debris. Air Duct Cleaning in Washougal

Dryer Vent Cleaning in Washougal
Dryer vent cleaning removes lint buildup from the appliance through the exterior termination. In Washougal, the same east winds that push dust through air ducts can force debris against exterior vent hoods, accelerating blockage. We clean the full run with rotary brushes and inspect for proper airflow at termination. Long vent runs in newer homes along SR-14 are especially prone to lint accumulation.

Duct Sealing in Washougal
Duct sealing closes leaks in supply and return ductwork using mastic sealant and metal-backed tape, applied at joints, seams, and connections. In Washougal, the thermal expansion from gorge-driven temperature swings loosens fittings over time, particularly in hilltop homes with flex duct. Sealing stops conditioned air from escaping into attics or crawl spaces and reduces the dust infiltration that comes with pressure imbalance. Duct Sealing in Washougal
