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.

Vashon isn’t a quick service call. The island’s ferry-locked geography means no running back to the shop for forgotten equipment, no same-day parts runs to a mainland distributor. Our technicians load Rotobrush rotary systems, Nikro negative-air HEPA units, and full agitation toolkits onto the boat before dawn. We’ve learned to work self-sufficiently because we have to. That discipline shapes how we price, how we schedule, and how we stand behind our work.
We’ve cleaned ducts in 1920s farmhouses near Burton, 1970s cabins off Cove Road, and custom builds overlooking Colvos Passage. The housing stock is varied and often aging, with original ductwork that’s undersized, retrofitted, or contaminated by the island’s unique combination of wood smoke, humidity, and rodent pressure. We don’t treat Vashon like a mainland suburb with a longer drive. It’s a different environment with different failure modes, and our approach reflects that.
Why Hollis Air Duct Cleaning Is Vashon’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our track record predates most competitors in the Puget Sound region. That longevity matters on Vashon, where word travels through island networks and a crew that shows up late or leaves a mess doesn’t get a second chance.
Our technicians are background-checked and uniformed. You know who’s arriving before they knock. They operate under The Garrison Standard, which means arriving inside the quoted window, pricing the job in writing before touching anything, completing the work by the book, and leaving the site clean. No exceptions.
Every job carries our 365-Day Done Right Promise. If the work fails within a year, we return and make it right at no charge, including a free second visit. That’s written on every invoice, not implied. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops, no callback queues.
We understand Vashon’s rhythms. We schedule around ferry wait times, plan for full-day commitments, and often bundle duct cleaning with chimney or HVAC services so islanders get more value from a single trip. Mainland companies rarely adopt this practice. We do because it makes operational sense for the customer.
Air Duct Inspection in Vashon
Air Duct Inspection in Vashon is where every job we do begins, and it’s especially critical here because island homes hide problems mainland inspectors rarely encounter. We use a Rotobrush camera system to feed high-resolution video through your supply and return lines, documenting creosote buildup from wood stoves, rodent droppings in retrofitted ductwork, and moisture staining from Vashon’s persistent humidity. A typical inspection runs $150 – $250 and includes a written report with photo documentation. Most Vashon homeowners need one before buying an older property, after smelling smoke or mustiness, or when airflow drops in rooms farthest from the air handler.
What We Document
Our inspection records duct material and condition, contamination type and severity, and any structural damage like separated seams or crushed flexible lines. On Vashon, we pay special attention to backdrafting signatures near wood stove connections and moisture intrusion points in crawl spaces or unconditioned attics. You’ll see exactly what we see. No guesswork, no pressure to buy services you don’t need.
When to Schedule
Book an inspection if you’ve noticed uneven heating, persistent odors, or increased dust after a winter of wood burning. For homes near unpaved roads or open land around Dockton or Maury Island, we also check for pollen and soil loading that accelerates duct contamination. The inspection takes 60 – 90 minutes and gives you a clear baseline.
Residential Air Duct Cleaning in Vashon
Residential Air Duct Cleaning in Vashon demands equipment and techniques matched to older, often modified systems that mainland crews misunderstand. We clean the full duct network, including supply trunks, return plenums, branch lines, and the air handler cabinet, using negative-air HEPA containment to prevent debris from re-entering your home. A complete residential cleaning in Vashon runs $350 – $650 depending on system size, contamination level, and accessibility. Homes heated primarily by wood stoves or with significant rodent history fall toward the higher end. We don’t quote per-vent teaser prices that balloon at the door. The price is written before we start.
Our Process
We seal registers and establish negative pressure with a Nikro HEPA filtration unit, then use mechanical agitation to dislodge debris from duct walls. For Vashon’s creosote and ash contamination, we may apply targeted cleaning agents compatible with your duct material, followed by thorough extraction. The system is re-inspected with video before we seal up. You’re invited to watch.
Wood Stove and Hybrid Systems
Many Vashon homes supplement or replace furnace heat with wood stoves, and ash backdrafts into ductwork through shared returns or poorly sealed joist bays. We address this by cleaning both the duct network and the points where combustion air intersects with conditioned air. Ignoring the source means rapid recontamination. We don’t ignore it.
Trusted Brands We Service in Vashon
We stock and install filtration products from Honeywell, Aprilaire, and Abatement Technologies, brands that hold up in Vashon’s demanding environment. Honeywell media filters handle high particulate loads from wood smoke and road dust without excessive pressure drop in older blower motors. Aprilaire whole-house systems integrate well with retrofitted ductwork common on the island. Abatement Technologies HEPA equipment is what we use for negative-air containment on every job. We carry common filter sizes and can source specialized media for systems that see heavier than average loading. Turnaround is same-visit for standard items because we load inventory knowing we can’t duck back to a mainland supplier mid-day.
Common Air Duct Cleaning Problems We See in Vashon Homes
- Creosote and ash infiltration from wood stoves. Backdrafting pushes combustion byproducts into return ducts, coating blower wheels and supply lines with sticky, acidic residue that standard dust removal won’t touch. We find this regularly in homes near Cove Road and along the island’s western ridge where wind patterns aggravate draft issues.
- Rodent contamination in crawl space and attic ducts. Vashon’s rural properties attract mice and rats seeking shelter, and original ductwork with gaps at seams or missing end caps becomes a highway. Droppings and nesting material carry pathogens and odors that circulate through living spaces until the ducts are properly cleaned and entry points sealed.
- Mold and mildew in high-humidity zones. The island’s maritime climate keeps relative humidity elevated, especially in unconditioned crawl spaces beneath 1940s – 1970s homes. Condensation on metal ducts supports microbial growth that releases spores into airflow. We document this with inspection cameras before recommending cleaning or remediation.
- Oversized or poorly matched filters in retrofitted systems. Homeowners upgrade to high-MERV pleated filters without checking whether the blower can handle the static pressure, or they jam the wrong size into a slot it doesn’t fit, bypassing filtration entirely. We measure airflow and recommend appropriate filtration for your actual system.

FAQs About Air Duct Cleaning in Vashon
Every 2 – 3 years for wood-stove-heated homes, versus 3 – 5 years for all-electric systems on the mainland. Wood ash and creosote accumulate faster than household dust, and Vashon’s humidity accelerates the problem by making particles cling to duct walls. If you smell smoke when the blower runs or see ash around registers, schedule an inspection regardless of interval. Call (361) 326-5060 for a free estimate.
Yes. Vashon has no bridge, so every job requires ferry transport from our Seattle office. We plan accordingly, loading all equipment for the day onto the boat and typically scheduling island work as full-day commitments. This logistical reality is why we often bundle duct cleaning with chimney or HVAC services, a practice mainland companies rarely adopt. Call (361) 326-5060 to discuss bundling options.
Wood heat prevalence and ferry-dependent logistics. Mainland crews deal with standard dust and pollen loading; Vashon crews face creosote, ash, and rodent contamination in aging systems, with no option to return to the shop for forgotten tools. The cleaning interval is shorter, the technician must be more self-sufficient, and bundling services saves customers money. Call (361) 326-5060 to schedule island service.
Yes. Well water and septic have no direct connection to ductwork, though we note that homes with these systems are often older properties with original or retrofitted ducts that need careful handling. We use contained, negative-pressure methods that don’t introduce moisture or chemicals into your living space, protecting both your air quality and your home’s systems. Call (361) 326-5060 for an inspection.
MERV 8 – 11 for most Vashon systems, with the specific choice depending on your blower’s capacity. Higher isn’t always better; MERV 13+ pleated filters restrict airflow in older blowers common on the island, causing ice-up or motor strain. We measure static pressure during inspection and recommend filtration that captures wood smoke particles and mold spores without overloading your equipment. Call (361) 326-5060 for a system assessment.
