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.

AfterFast, Reliable Air Duct Cleaning Across Vashon
Air duct cleaning in Vashon typically runs $350-$650 for a whole-home system, and most jobs are scheduled within a few days of your call. We’re one of the few mainland crews that regularly makes the Washington State Ferry run to Vashon Island, so island homeowners aren’t stuck with the handful of local options or contractors who simply won’t cross the water.
We’ve been dispatching from our Seattle office to Vashon homes since 2005, and we know the island’s rhythms: the ferry schedule, the older farmhouses along Cemetery Road, the mid-century ranches tucked into the trees above Ellisport. Our technicians arrive with shoe covers, drop cloths, and a written price before any work starts. Paul Adeyemi built Morton’s on the idea that families deserve to know exactly what will happen in their house and exactly what it will cost. Call us at (323) 918-4345 for a free estimate.
Why Morton’s Air Duct Cleaning Is Vashon’s Preferred Air Duct Cleaning Company
Vashon residents call us back because we treat the ferry ride as part of the job, not an excuse to charge extra or rush through. Our background-checked, uniformed technicians work to the Cedarwell C.A.R.E. values: shoe covers and drop cloths on every visit, quiet tools during nap hours, pet-safe product choices where available. We know many Vashon homes have dogs that greet strangers at the door and toddlers napping down the hall.
Every job carries the 365-Day Done Right Promise stamped on the invoice. If it’s not right, we make it right. No exceptions. We also leave a photo of the clean-up before the crew departs, so you see the home was left better than we found it.
A live person answers our phone 24/7. Not a voicemail, not a chatbot. When you’re trying to coordinate a ferry-dependent appointment around work and school schedules, that matters.
Air Duct Repair in Vashon
Air Duct Repair in Vashon almost always involves fixing what decades of deferred maintenance and Puget Sound moisture have damaged inside crawlspaces and behind air handlers. Original oil- or propane-era duct runs in older farmhouses and ranches develop cracked, disconnected joints that dump conditioned air into the crawlspace instead of the rooms. A typical repair runs $180-$450 per section, with full replacement of collapsed flex duct at the higher end.
Disconnected and Crushed Supply Branches
We find these constantly in Vashon homes. The original flex gets bumped during crawlspace work, or the wire helix fatigues after forty years. Our crew re-secures the branch, replaces damaged sections with new flex rated for the application, and seals every joint with mastic so air actually reaches the register.
Mold-Damaged Flex and Trunk Connections
When condensation has saturated the duct lining, cleaning alone won’t fix it. We cut out the affected flex, treat the surrounding framing if needed, and install new material. The repair is always photographed and explained before we start.
Ductwork Cleaning in Vashon
Ductwork Cleaning in Vashon means source removal from supply and return runs that may not have seen professional attention since the house was built. Our Air Duct Cleaning team uses Rotobrush and Nikro equipment for agitation and negative-pressure extraction, not a shop vacuum pushed into a register. A typical whole-home cleaning runs $350-$650, depending on system size and accessibility.
Source Removal for Decades of Accumulation
Surface-wiping the registers does nothing for the packed debris inside the trunk lines. Our process involves sealing the system, applying mechanical agitation to dislodge buildup, and extracting it under controlled negative pressure. We run a video inspection afterward so you see the difference.
Sealing the System After Cleaning
Cleaning reveals the real problems: disconnected joints, gaps at the plenum, crushed runs. We quote sealing work separately, with a written price before any repair begins. A sealed system moves more air, runs quieter, and stays cleaner longer.
Trusted Brands We Service in Vashon
We clean and service systems with components from Honeywell, Aprilaire, and Abatement Technologies, and we carry common parts for these brands on our service vans. That matters on Vashon. Missing a part doesn’t mean a quick run to the supply house; it means another ferry trip and another day. Our technicians arrive prepared for the brands we encounter most often in island homes, which speeds turnaround and keeps your appointment on schedule.
Common Air Duct Cleaning Problems We See in Vashon Homes
- Mold colonization in dormant ductwork. Part-time residences that sit unheated from October through March develop damp, dark conditions inside crawlspace flex runs. When the furnace fires up in April, the first air cycle distributes spores through every room.
- Disconnected joints from original oil- or propane-era installations. Decades of thermal cycling and occasional crawlspace traffic loosen connections at the plenum and branch takeoffs. Conditioned air leaks into the crawlspace, utility bills climb, and rooms stay cold.
- Crushed or kinked flex duct behind air handlers. Tight installations from the 1970s and 1980s left inadequate service clearance. Over time, the flex compresses or tears, creating a blockage that reduces airflow to entire zones of the house.
- Debris packed deep in supply and return trunks. Without regular cleaning, lint, insect fragments, and construction dust layer up in the main runs. A register vacuuming doesn’t touch this material; it requires sealed-system extraction.

FAQs About Air Duct Cleaning in Vashon
Yes. We schedule Vashon appointments regularly and factor the ferry into our routing without extra travel charges. Most mainland HVAC contractors decline the trip, which is why we’ve made it a standard part of our service area since 2005. Call (323) 918-4345 to check current ferry timing and book a slot.
Expect a musty odor and possibly visible dust on first startup. Months of damp, unheated ductwork let moisture accumulate inside flex runs, especially in crawlspaces. We recommend a pre-season inspection in March or early April before you occupy the house. If mold is present, we’ll show you camera footage and quote cleaning plus any needed repairs before work begins.
Usually cleaning plus targeted repair. Original flex that is intact but dirty responds well to source removal and sealing. We replace sections only where the material is crushed, disconnected, or mold-saturated beyond recovery. Our technician will show you camera footage of the actual condition and quote each option separately.
Vashon’s combination of ferry-only access, persistently high marine humidity, and a high proportion of part-time residences creates perfect conditions for mold growth inside dormant ductwork. Mainland contractors rarely serve the island, so maintenance gets deferred. When homes sit unheated through the wet season, condensation accumulates in crawlspace flex runs and mold colonizes the interior lining. The spring furnace startup then distributes spores through the entire house. It’s a seasonal pattern our techs see repeatedly that mainland suburbs rarely encounter.
No. We seal the system, use Rotobrush and Nikro agitation tools to dislodge debris from the interior walls of supply and return runs, and extract it under negative pressure. We inspect with a camera before and after. Register wiping is not duct cleaning. The process takes 3-5 hours for a typical Vashon home, and we protect floors and furniture with drop cloths throughout. Call (323) 918-4345 for a free estimate and written price.
A part-time owner near Ellisport Road called us in April after her first furnace run of the year pushed a musty, visible dust cloud out of the registers. Our tech ran camera inspection inside the return trunk and found the original 1970s flex runs in the crawlspace wet with condensation and dotted with mold, plus a crushed supply branch behind the air handler. We set up negative pressure, used agitation tools for source removal, replaced the failed flex, and sealed the disconnected joints so the system actually moved air again.
