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 Mountlake Terrace, WA
Air duct cleaning in Mountlake Terrace runs $350 – $650 for a typical whole-home system, with most jobs completed in a single visit. What drives the price here isn’t just square footage; it’s the condition of mid-century galvanized ductwork that has spent seventy years in damp Pacific Northwest air. We dispatch crews from our Seattle office to serve Mountlake Terrace directly, and we carry the rotary brush systems and negative-air machines needed for both original steel ducts and newer flexible runs. Call (361) 326-5060 for a written estimate before any work starts.
Why Mountlake Terrace Homes Are Different
Mountlake Terrace’s post-WWII housing boom left a legacy of 1950s-60s ramblers and split-levels with original galvanized ductwork that, in the Pacific Northwest’s damp climate, becomes a haven for mold and mildew. That makes air duct cleaning here less about dust removal and more about mold remediation. The city’s proximity to Puget Sound adds salt-laden humidity that corrodes ducts from the inside out, a problem we rarely see when we work inland.
Most homes in Mountlake Terrace were built between 1945 and 1970. The original galvanized steel ducts are prone to rust and mold growth, while newer infill townhomes have flexible plastic ducts that collect dust differently and need gentler handling. In the Melody Hill neighborhood, original floor registers pull in pollen from surrounding Douglas firs, creating a distinct spring rush when pollen counts spike. Crawlspaces and attics here stay damp year-round, so we often find biofilm inside supply lines that a simple vacuum won’t touch.
Our Main Mountlake Terrace Services
Mountlake Terrace homeowners call us for three jobs, each handled with its own equipment and approach:
Air Duct Cleaning in Mountlake Terrace
We clean the full supply and return network using a Rotobrush rotary brush system for flexible ductwork and Nikro negative-air machines for rigid galvanized lines. In Mountlake Terrace, we expect to find rust scaling and mold inside original steel ducts, so we inspect with a camera before we quote. The job includes all registers, the main trunk, and the plenum. Air Duct Cleaning in Mountlake Terrace is priced per system, not per vent, with the full cost written down before we start.
Dryer Vent Cleaning in Mountlake Terrace
Dryer vent cleaning in Mountlake Terrace addresses a fire hazard that builds faster in humid climates where lint clumps with moisture. We run a rotary brush through the full vent line to the exterior cap and measure airflow before and after. Homes with long vertical runs through original construction, common in split-levels here, need this service more often than single-story layouts. Dryer Vent Cleaning in Mountlake Terrace takes 45 – 90 minutes and comes with a written airflow reading.
Duct Sealing in Mountlake Terrace
Duct sealing closes the gaps and seams that leak heated air into crawlspaces and attics. In Mountlake Terrace, we apply mastic sealant to original galvanized joints that have worked loose over decades, or use aerosol-based sealant for flexible duct systems in newer townhomes. Sealing can drop a home’s heating load by 20 – 30% when leakage is severe. Duct Sealing in Mountlake Terrace starts with a pressure test so you see the leakage in real numbers before deciding.
