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.
Fast, Reliable Air Duct Cleaning Across Burien
Air duct cleaning in Burien typically runs $350 – $650 for a whole-home system, with most residential jobs completed in a single visit. Our crews dispatch from the Seattle office and cover Burien neighborhoods from Three Tree Point to Seahurst to the commercial corridors along Ambaum Boulevard. We’ve worked on enough Burien homes to know the difference between a quick register wipe and the real work this climate demands. Call (361) 326-5060 for a free written estimate.
Burien’s marine West Coast climate, with mild, wet winters and persistent dampness, creates a year-round mold and mildew risk inside ductwork that is largely absent in drier inland cities. The combination of older housing stock with original metal ductwork and high indoor humidity means Air Duct Cleaning here is as much about moisture control and mold remediation as it is about dust removal. That’s why our Burien crews carry moisture meters and camera gear alongside rotary brushes and HEPA vacuums.
Why Hollis Air Duct Cleaning Is Burien’s Preferred Air Duct Cleaning Company
We’ve been sending crews to Burien since 2004 as part of the Garrison Partners family, and we’ve built our reputation on showing up inside the window, pricing in writing, and leaving the site clean. The Garrison Standard applies to every job: written price before work starts, background-checked uniformed technicians, and the 365-Day Done Right Promise backed in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit.
Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday. When you schedule Air Duct Cleaning in Burien, you know who is walking into your home before they arrive. We don’t compete on the lowest teaser price. We compete on discipline: show up when we said, price it before we touch it, do it by the book.
Roy Castellanos leads our operation, and The Garrison Code governs how every technician behaves on a job. That means boot covers, drop cloths, and explaining what the equipment does before switching it on. Burien homeowners have been burned by no-shows and prices that jumped at the door. We fix that with operational specifics, not adjectives.
Air Duct Repair in Burien
Air Duct Repair and Duct Sealing - Burien usually means fixing the damage that decades of damp marine air have done to original galvanized steel systems, plus the disconnected or crushed branch runs hiding behind finished basements and crawlspaces. Much of Burien’s housing consists of mid-century (1940s – 1960s) single-family ramblers and split-levels, many with original galvanized steel duct systems that are prone to internal condensation and surface rust in the damp climate. These older ducts often have loose, deteriorating interior insulation that can trap moisture and harbor mold. Repair costs in Burien typically range from $180 for a simple reconnection to $850 for replacing a rusted trunk section with sealed, insulated duct.
Disconnected and Crushed Runs
We find these behind finished basement ceilings and in crawlspaces throughout Burien’s older neighborhoods. A disconnected branch run means your blower is heating or cooling an unfinished space instead of your bedroom. We locate the break with a camera, reconnect with mechanical fasteners and mastic sealant, and test static pressure before we leave.
Rusted Galvanized Duct Replacement
Original 1940s – 1960s galvanized ducts condense in Burien’s damp air, causing surface rust that eventually pinholes and leaks. We cut out the damaged section and replace with insulated flex or sheet metal, sealed to modern standards. The goal is stopping the moisture cycle, not just patching the symptom.
Ductwork Cleaning in Burien
Ductwork Cleaning in Burien addresses the dust, debris, and biological growth that accumulate in systems running through a wet climate with high indoor humidity. Burien’s wet, marine climate (avg. 38+ inches of rain per year, frequent winter drizzle) means relative humidity indoors often stays above 60%, especially in crawlspaces and basements. This dampness encourages mold growth inside ductwork and makes regular duct cleaning and moisture inspection essential. A typical whole-home ductwork cleaning in Burien runs $350 – $650, with larger split-levels or homes with multiple zones toward the higher end.
Rotary Brush Agitation with HEPA Filtration
We use Rotobrush rotary brush systems to dislodge debris from duct walls, coupled with Nikro negative-air machines that maintain suction and capture particles down to 0.3 microns. The brushes spin at controlled speed so they clean without damaging the thin metal of older galvanized systems. Every pass is visible on our monitor.
Moisture Assessment and Source Identification
Cleaning alone doesn’t stop mold from returning. We check crawlspace vapor barriers, duct boot seals, and trunk line insulation for condensation points. If we find a sweating line or leaky boot, we flag it in writing so you can address the moisture source before the next cleaning cycle.
Trusted Brands We Service in Burien
Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. These are professional-grade tools, not hardware-store gear. We stock common replacement parts locally for Burien customers, so when a repair follows a cleaning, we’re not ordering components and making you wait. The same brands appear in commercial buildings across King County. We bring that standard to your rambler in Burien.
Common Air Duct Cleaning Problems We See in Burien Homes
- Standing condensation in floor registers. After a wet Puget Sound winter, technicians in Burien’s Three Tree Point and Seahurst neighborhoods routinely find mildew and standing condensation inside floor registers of 1950s ramblers. A failure mode rarely seen in drier, colder cities east of the Cascades.
- Deteriorating interior insulation trapping moisture. Original fiberglass liner inside galvanized branch runs breaks down over decades, creating pockets where humidity collects and mold establishes. We remove the degraded material and treat the metal surface before sealing.
- Crushed or disconnected branch runs hidden from view. These sit behind finished basement ceilings and in tight crawlspaces, so dust and moisture can’t be pulled to the air handler. Cleaning only the visible registers leaves the real problem untouched.
- Recolonizing mold from uncorrected moisture sources. High indoor humidity lets mold return within months if the underlying source, crawlspace vapor, leaky boots, or a sweating trunk line, isn’t corrected alongside the clean. We flag these in our written report.

FAQs About Air Duct Cleaning in Burien
Burien’s marine climate keeps indoor relative humidity above 60% for much of the year, so mid-century galvanized steel ducts here rust, sweat, and grow mildew in ways drier inland cities east of the Cascades never see. The constant dampness creates condensation on cool metal surfaces that inland climates simply don’t produce. Moisture control is as central to duct cleaning here as dust removal. Call (361) 326-5060 and we’ll inspect for the specific source.
In a 1954 rambler off SW 152nd in Seahurst, we pulled a floor register and found standing condensation and black mildew speckling the original galvanized branch run. After camera inspection we ran agitation tools and HEPA filtration under negative pressure to remove the source, then sealed a crushed, disconnected run under the hall and treated the air handler’s interior insulation. The blower motor amp draw dropped and the family’s musty “old house” smell went with it. That’s typical of what we find in Burien’s mid-century stock.
Cleaning alone rarely fixes a musty smell if the moisture source remains. We identify and report crawlspace vapor issues, leaky duct boots, or sweating trunk lines that let mold recolonize supply and return ducts within months. The written report includes what we found and what needs correction beyond the clean. Call (361) 326-5060 for an inspection that addresses the cause, not just the symptom.
We run a video camera through the full system before and after cleaning, and we show you the footage. The 365-Day Done Right Promise covers our work for a full year. If the musty smell returns or you suspect we missed a section, we come back at no charge. Written guarantee, not a verbal assurance.
Late spring, after the heaviest rains subside but before summer humidity rises, is ideal for Burien homes. This timing lets us assess winter moisture damage and address it before warm-weather humidity compounds the problem. Homes with visible mold, persistent musty odors, or recent water intrusion should schedule immediately regardless of season. Call (361) 326-5060 to book a free estimate.
