Fast, Reliable Air Duct Cleaning Across Poulsbo
Air duct cleaning in Poulsbo typically costs $350–$850 for a full residential system, with most jobs completed in a single visit. We’re usually on-site within 24–48 hours of your call, and we bring equipment built for the specific moisture problems this ZIP code throws at ductwork.
We’ve been crossing the Hood Canal Bridge to reach Poulsbo homes since 2013, and we’ve learned that duct cleaning here isn’t the same job it is in drier parts of Kitsap County. Our Air Duct Cleaning team knows the hillside neighborhoods above Liberty Bay, the crawl spaces off Viking Avenue, and the 1970s split-levels near Poulsbo Village where original flex duct has been sitting in damp soil for forty-plus years. Richard Anderson, our owner and lead technician, personally runs every job. Call (877) 335-1974 for a free estimate.
Why Landmark Air Duct Cleaning Service Washington Is Poulsbo’s Preferred Air Duct Cleaning Company
Our reputation in Poulsbo was built one crawl space at a time. Homeowners here talk to each other—at the farmers market, at Liberty Bay Books, on Nextdoor—and word travels when a technician actually shows up prepared for what local ductwork looks like. We’re not a general HVAC company that added duct cleaning as an upsell; this is the only trade we’ve practiced for 11 years.
732 customers and counting have left reviews averaging 4.9 stars. That volume matters because it means we’ve seen the specific failure patterns that repeat in Poulsbo’s housing stock: the mold at flex duct joints, the condensation on rigid duct in unconditioned crawl spaces, the musty blast when furnaces kick on after sitting idle. Richard Anderson doesn’t delegate this work to rotating crews. He’s owner-led on every job, running the same Rotobrush and Nikro equipment that commercial restoration contractors use.
From our Seattle base, we schedule Poulsbo routes to minimize drive time and keep response windows tight. Most calls get a next-day or same-week slot. We know which hillside roads flood in heavy rain, which neighborhoods have the oldest crawl-space access, and why a standard vacuum-only cleaning would waste your money here.
Our Air Duct Cleaning Services in Poulsbo
Residential Duct Cleaning
Poulsbo’s homes demand more than debris removal. The craftsman cottages near Front Street and the split-levels off Finn Hill Road have duct systems that have been breathing humid marine air for decades. We clean the full supply and return network, then inspect for moisture intrusion points that will bring mold back within weeks if left unaddressed. A typical residential job in Poulsbo runs $350–$650 for standard systems, $650–$850 if crawl space remediation is needed alongside.
Commercial Duct Cleaning
Businesses along Highway 3 and in the Poulsbo Village retail corridor need minimal disruption. We schedule early mornings or weekends, use contained Rotobrush systems that don’t vent debris into occupied spaces, and document with video inspection for property managers who need records for insurance or lease compliance. Commercial pricing starts around $800 and scales with system complexity.
Supply Duct Cleaning
Supply lines in Poulsbo homes often run through the dampest parts of the structure—crawl spaces where 55 inches of annual rainfall keeps soil perpetually moist. We remove biological contamination from these lines, then seal joints where warm interior air hits cold duct exteriors and creates condensation. This is where most of the musty odor originates.
Return Duct Cleaning
Returns pull air from every room, and in Poulsbo’s humid climate they also pull moisture. We find return plenums in older homes near Liberty Bay coated with mold that standard filters never catch. Our Nikro HEPA-contained systems remove this contamination without redistributing spores through the house.
Full System Cleaning
This is what most Poulsbo homes actually need. We clean supply ducts, return ducts, the plenum, registers, and the air handler cabinet as one integrated system. Partial cleaning leaves living contamination in connected components. Full system jobs in Poulsbo range from $550–$950 depending on home size and crawl space condition.
Video Inspection
Before we quote and after we finish, we run camera-equipped scopes through your ductwork. In Poulsbo, this reveals what homeowners can’t see: condensation pooling at low points, mold colonies behind damp insulation, deteriorated flex duct that needs replacement rather than cleaning. The footage belongs to you, and it often explains symptoms—musty odors, allergy flare-ups, uneven heating—that homeowners had accepted as normal.

Trusted Brands We Service in Poulsbo
We clean with professional-grade Rotobrush and Nikro systems—the same equipment restoration contractors deploy after water damage, not rental-shop vacuums with brushes duct-taped to the hose. For homes that need air quality improvement beyond cleaning, we install and service Honeywell and Aprilaire whole-house filtration, plus Abatement Technologies antimicrobial treatments and Guardsman sealants for duct joints. We don’t have to order parts from Seattle; our trucks carry the common sizes and treatments Poulsbo homes need, so we’re not making you wait for a second visit.
Common Air Duct Cleaning Problems We See in Poulsbo Homes
- Mold returns within weeks if crawl space moisture isn’t addressed. We’ve cleaned ducts in hillside homes near Noll Road, only to get callback requests six months later because the crawl space itself was never dried or sealed. Duct cleaning without moisture control is temporary.
- Original flex duct from the 1970s–1990s has deteriorated beyond cleaning. The porous material traps mold in its fibers. Vacuuming the surface leaves living colonies inside. We identify this with video inspection and recommend replacement rather than waste your money on cleaning.
- DIY duct cleaning kits push spores deeper. Homeowners in Poulsbo’s competitive real estate market sometimes try to prep a house for sale with rented equipment. These units lack HEPA containment and adequate suction for humid-region contamination. We’ve been called after DIY attempts made the problem worse.
- Furnace restart after idle periods blasts stagnant, mold-laden air. Poulsbo homes rarely use air conditioning, so systems sit through mild stretches then force heated air through ducts that have been accumulating moisture for months. The first cold snap each fall brings our busiest call volume.

What moves you within these ranges?

FAQs — Air Duct Cleaning in Poulsbo
Because Poulsbo’s persistent marine humidity—relative humidity above 80% for much of the year—keeps crawl spaces moist enough to support mold growth on duct exteriors. Cleaning the interior of ducts without addressing the moisture source that contaminates them from outside is temporary. We regularly find active condensation at duct joints in hillside crawl spaces, and experienced local contractors factor this into quotes for 98370. Call (877) 335-1974 if you want us to inspect your crawl space alongside your ductwork.
Yes. The 1970s–1990s flex duct common in Poulsbo’s split-level and tract homes is porous and deteriorating after 30–50 years in damp crawl spaces. Mold embeds in the fiber material where vacuums can’t reach it. Video inspection lets us show you whether your flex duct is cleanable or needs replacement. In a 1970s split-level on Viking Avenue, our crew used Rotobrush equipment to clean flex ducts in a damp crawl space. We found active condensation and mold colonies at every joint, which we remediated with Abatement Technologies antimicrobial treatment. The homeowner reported immediate relief from musty odors.
Every 3–5 years for homes with good moisture control; every 2–3 years if your crawl space stays damp or you’ve had prior mold issues. The marine humidity here accelerates biological growth compared to drier inland markets. Homes with duct runs through unconditioned crawl spaces over moist Kitsap soil need more frequent inspection, not just cleaning. Call (877) 335-1974 to schedule a video inspection and we’ll tell you where your system falls.
It can, if the odor originates in the duct system itself. Musty smells that worsen when the furnace kicks on typically come from mold in supply ducts or the plenum. We remove that contamination and treat with antimicrobial products. If the odor persists, the source may be crawl space soil, deteriorated insulation, or standing water beneath the vapor barrier—issues we identify during our inspection and can address. Call (877) 335-1974 for a free evaluation.
We clean with Rotobrush and Nikro professional-grade systems, and for homes needing air quality improvement beyond cleaning, we work with Honeywell, Aprilaire, Abatement Technologies, and Guardsman products.

Our trucks stock the common sizes and treatments so Poulsbo jobs don’t wait on Seattle deliveries. Call (877) 335-1974 to discuss what your specific system needs.
