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 Normandy Park
Air duct cleaning in Normandy Park typically runs $380-$620 for a complete residential system, with most jobs scheduled within a week and completed in a single visit. Our crews serve Normandy Park from our Seattle dispatch office, so we’re familiar with the local housing stock, the SeaTac flight-path conditions, and the specific contamination patterns that show up in homes here. Call (469) 972-3151 for a free written estimate before any work begins.
We’ve been cleaning ducts in Normandy Park long enough to know what separates a routine service call from one that reveals real problems. The custom homes built between the late 1950s and mid-1970s, when Normandy Park incorporated as its own city distinct from Burien, carry original sheet-metal duct systems that are now fifty-plus years old. That age matters. Cloth-and-mastic tape joints fail. Flex-duct retrofits crush behind air handlers. And the unique location here, directly beneath SeaTac International Airport’s approach corridors, means ultrafine jet-exhaust particulates enter HVAC intakes at rates that drop off sharply just a few miles east or north. Our Air Duct Cleaning team treats Normandy Park as a distinct service area with distinct problems, not a generic suburb.
Why Kestrel Air Duct Cleaning Is Normandy Park’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Normandy Park on showing up in the window we promised and putting the price in writing before touching a single vent. The Kingswell Guarantee, which governs every job we do, was established in 2004 and hasn’t changed: written price first, defined arrival window, clean job site, and a written guarantee with a free return visit if the work fails within the guarantee period. Dale Whitmore leads our operation, and that standard applies to every Normandy Park home we enter.
Our technicians are background-checked and uniformed, and they arrive with professional-grade equipment, not box-store shop vacs. We use Rotobrush rotary brush systems to dislodge debris at the duct wall, Nikro negative-pressure units to pull contaminants out, and Abatement Technologies HEPA filtration to keep loosened particles out of your living space during cleaning. Calls are answered by a live person, 24/7, not a voicemail queue. And our 365-Day Done Right Promise is documented in writing on every job, not a vague satisfaction pledge. If the work falls short within that year, we return and make it right at no charge.
Normandy Park homeowners have told us the same story repeatedly: they hired a cheap coupon service, the crew showed up with a shop vac and a brush on a drill, and six weeks later the dust was back. We don’t do that. We show you before-and-after photos of your own ducts, not stock images. And the price we write down is the price you pay.
Air Duct Repair in Normandy Park
Air Duct Repair in Normandy Park addresses the mechanical failures we find inside fifty-year-old forced-air systems that standard cleaning alone cannot fix. Most calls start with a homeowner noticing weak airflow, uneven heating, or a blower motor that runs longer than it should. We inspect with a video camera, locate the damage, and repair it before running our cleaning equipment. Typical Air Duct Repair in Normandy Park runs $180-$450 for minor joint sealing and small section replacement, or $600-$1,200 when we need to replace multiple crushed or disconnected runs behind the air handler.
Crushed Flex-Duct Replacement
On bluff-side streets like those along Marine View Drive, we regularly find flex-duct additions from past retrofits that have been crushed by storage items in crawl spaces or compressed by decades of settling. The blower motor strains against the blockage, airflow drops, and debris recirculates. We cut out the damaged section, install proper gauge replacement duct, and support it so the problem doesn’t return.
Joint Sealing with Modern Materials
Original cloth-and-mastic tape on sheet-metal joints dries and fails over time. We remove the old material, clean the mating surfaces, and seal with foil tape and mastic rated for duct systems. This stops the leakage that pulls jet-exhaust particulates and marine moisture into living spaces, and it improves system efficiency immediately.
Ductwork Cleaning in Normandy Park
Ductwork Cleaning in Normandy Park means source removal of accumulated debris from the entire forced-air system, including supply ducts, return ducts, and the air handler cabinet. We don’t just vacuum the vents you can see. Our process uses brush agitation, negative-air extraction, and HEPA filtration to remove what has built up over decades. A typical Ductwork Cleaning in Normandy Park runs $380-$620 for a complete residential system, with larger homes or systems with heavy contamination toward the upper end.
Negative-Air Extraction Process
We connect a Nikro negative-pressure unit to your duct system, creating suction that pulls loosened debris toward our collection equipment. This isn’t a shop vac. The unit maintains continuous negative pressure throughout the cleaning, so particles that our Rotobrush dislodges don’t escape into your home. Abatement Technologies HEPA filtration on the exhaust ensures what we capture stays captured.
Supply and Return Duct Cleaning
Supply ducts push conditioned air to your rooms. Return ducts pull air back to the air handler. Both sides need attention, but the return side usually carries more debris because it’s the intake path. We clean both, plus the air handler cabinet, so the system doesn’t immediately recontaminate itself on the first heating cycle.
Trusted Brands We Service in Normandy Park
We stock parts and filtration products from Honeywell, Aprilaire, and Guardsman for Normandy Park homeowners who want to maintain clean air between service visits. Aprilaire media air cleaners upgrade standard filter slots to capture finer particles, including the ultrafine jet-exhaust particulates that are a persistent background load here. Guardsman UV systems install in the air handler to inhibit biological growth on the coil, which matters in Normandy Park’s marine-moisture environment. We carry common sizes on our trucks, so most replacements happen during the same visit, not a return trip next week.
Common Air Duct Cleaning Problems We See in Normandy Park Homes
- Dual contamination from SeaTac flight paths and Puget Sound moisture. Homes beneath the airport corridors accumulate ultrafine jet-exhaust particulates at rates not seen a few miles inland. Bluff-side properties add salt-laden marine moisture and biological staining near return-air intakes. The combination produces a contamination signature unique to this location.
- Fifty-year-old sheet-metal systems with failing original seals. Cloth-and-mastic tape joints from the 1960s and 1970s have dried and cracked, allowing conditioned air to leak into attics and crawl spaces while pulling unfiltered air, pollen, and particulates into the return stream.
- Crushed or disconnected flex-duct retrofits hidden from view. Previous owners often added flex duct without proper support. Over decades, these runs compress behind air handlers or sag in crawl spaces, restricting airflow and creating debris traps that standard vent cleaning misses entirely.
- Deteriorating inner duct liner shedding fibrous debris. Older flex-duct sections with degraded inner liners release particles into the airstream. The material traps alder pollen and ultrafine particles instead of letting filters capture them, and it continues shedding until the section is replaced.

FAQs About Air Duct Cleaning in Normandy Park
Your home sits directly beneath SeaTac International Airport’s approach and departure corridors, exposing HVAC intakes to a chronic background load of ultrafine jet-exhaust particulates that infiltrate at rates dropping off sharply just a few miles east or north. Combined with Puget Sound bluff moisture that promotes biological growth in older ductwork, this dual contamination signature means Normandy Park ducts accumulate debris faster than inland suburbs. Call (469) 972-3151 for a video inspection and written estimate.
That residue is actual salt and mineral deposits from marine air drawn off Puget Sound, a pattern we consistently find on bluff-side properties in Normandy Park and rarely see even half a mile inland toward the SeaTac corridor. It indicates moisture infiltration through failing duct seals or gaps in the return path, and it promotes biological staining on duct walls. We address it by sealing the return ductwork and removing the accumulated deposits with source-removal cleaning.
They need inspection first. Original sheet-metal ducts from the late 1950s through mid-1970s often have failing cloth-and-mastic tape joints that leak air and pull in contaminants. We use video inspection to check for crushed flex-duct retrofits, deteriorating inner liner, and joint failures before recommending cleaning alone or cleaning plus repair. The written estimate includes our findings and a clear recommendation.
Yes. The heavy native canopy of red alder, big-leaf maple, and Douglas fir around Normandy Park produces an intense alder pollen surge from February through March that overwhelms standard filters and drives fine particulate deep into duct systems. Homeowners who notice increased allergy symptoms during this period often benefit from more frequent filter changes and thorough duct cleaning to remove accumulated pollen from previous seasons.
We use contained negative-air extraction with Abatement Technologies HEPA filtration, so loosened debris travels directly to our collection unit rather than escaping into your living space. Technicians lay protective coverings, wear shoe covers, and leave the job site cleaner than they found it, per The Kingswell Way. We also show you before-and-after photos of your own ducts so you can verify the work without crawling into the attic yourself.
