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 Poulsbo
Air duct cleaning in Poulsbo typically runs $350 – $650 for a complete residential system, and most jobs are scheduled within a few days of your call. We dispatch crews from our Seattle office to serve Poulsbo directly, and we’ve worked enough homes near Front Street, along Liberty Bay, and out toward Noll Road to know what your system is likely hiding.
Poulsbo’s mix of 1940s bungalows, waterfront cottages, and newer construction on the outskirts means no two duct systems are the same. The damp marine air coming off Puget Sound, the heavy tree canopy that keeps things shaded and moist, and the original duct materials in older homes all create conditions you won’t find inland. That’s why our Air Duct Cleaning team treats Poulsbo as its own category, not a generic suburb. Call (361) 326-5060 and we’ll give you a written price before any work starts.
Why Hollis Air Duct Cleaning Is Poulsbo’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our Poulsbo customers keep calling back because we show up when we said we would, price the job in writing before touching anything, and leave the site clean. The Garrison Standard isn’t a slogan, it’s an operational checklist: arrive inside the quoted window, write the price down, complete the job by the book.
Our technicians are background-checked and uniformed. You’ll know who’s walking into your home before they arrive. Every job carries our 365-Day Done Right Promise in writing. If the work fails within a year, we come back and make it right at no charge, including a free second visit. No negotiation, no runaround.
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 for a scheduling question.
We know the local conditions that shape your ductwork: the marine layer that keeps crawlspaces damp, the original galvanized ductwork in pre-1960 homes, the retrofitted systems in split-levels near Highway 3. That local knowledge means we bring the right equipment and the right approach the first time.
Vent Cleaning in Poulsbo
Vent cleaning in Poulsbo removes the accumulated dust, pollen, and organic debris that collects at your supply and return registers, especially in homes under the heavy Douglas fir and cedar canopy that surrounds the city. We use rotary brush systems from Rotobrush combined with negative-air machines from Nikro to agitate and extract debris without pushing it deeper into the system. A typical vent cleaning as part of a full system service in Poulsbo runs $150 – $280 for supply and return registers combined.
When Registers Tell the Real Story
Black streaking around your ceiling or floor vents usually means the system is pulling air from somewhere it shouldn’t, often a damp crawlspace or a disconnected boot behind the wall. In Poulsbo’s older homes, we see this pattern constantly. Cleaning the vent face alone won’t fix it. We trace the source, show you what the camera found, and quote the repair in writing before touching anything.
Supply vs. Return: Different Loads, Different Tools
Supply vents push conditioned air into your rooms and tend to collect fine dust and pet dander. Return vents pull air back to the handler and act as the system’s intake filter, so they load up faster with larger debris and, in Poulsbo, with mold spores from damp crawlspaces. We match the agitation tool to the duct material: softer brushes for original fiberboard in downtown homes, stiffer rotary heads for metal ductwork in newer construction.
Air Duct Repair in Poulsbo
Air Duct Repair in Poulsbo often starts with a cleaning call and ends with resealing, reconnecting, or replacing failed duct runs that we find during inspection. The damp crawlspaces in historic downtown and waterfront homes destroy connections over time. Metal rusts, tape fails, and fiberglass liner delaminates. A typical repair runs $200 – $500 for reconnection and resealing, or $800 – $1,400 if we need to replace a crushed or deteriorated run with new ductwork.
Crawlspace Failures We Find Weekly
Disconnected boots, crushed flexible duct, and rusted metal seams are standard findings in Poulsbo crawlspaces. The marine air keeps humidity above 60% year-round, and without proper vapor barriers, that moisture condenses on cold duct surfaces. We document everything with video inspection, quote the repair separately from the cleaning, and get your written approval before starting.
Duct Sealing With Mastic, Not Tape
We seal repaired joints with mastic, a brush-applied compound that remains flexible and airtight for decades. Duct tape fails in damp conditions, which means it fails in Poulsbo. Our sealing work is part of The Garrison Code: if we open it, we close it right, and we guarantee it for 365 days.
Trusted Brands We Service in Poulsbo
We carry professional-grade equipment and filtration products from Rotobrush, Aprilaire, Abatement Technologies, and Guardsman. That means when your Poulsbo home needs a new filter housing, a UV light installation, or upgraded MERV filtration after a mold remediation, we stock the parts locally and can often complete the upgrade same visit. No waiting for Seattle supply houses to deliver. Our Nikro negative-air machines and Rotobrush rotary systems are the same tools commercial crews use on hospitals and schools, scaled down for residential work and operated by technicians trained on The Garrison Standard.
Common Air Duct Cleaning Problems We See in Poulsbo Homes
- Mold and mildew in original duct liner. The fiberglass liner inside pre-1980 ductwork acts like a sponge in Poulsbo’s damp crawlspaces. Once mold colonizes it, no amount of surface cleaning reaches the roots. We remove the contaminated liner or replace the run entirely, then seal the new duct with mastic.
- Crushed flexible duct in crawlspaces. Original flexible duct installed in the 1970s and 1980s collapses under its own weight when the wire helix rusts through. The system still runs, but airflow drops by half and the furnace works harder. We replace with properly supported metal or modern flex duct rated for damp locations.
- Disconnected return pathways pulling crawlspace air. In historic downtown Poulsbo homes near Front Street, we’ve found return ducts completely separated from the air handler, sucking musty crawlspace air straight into the living space. The homeowner smells it every time the heat kicks on. Reconnection and sealing fixes it permanently.
- Retrofit ductwork mismatched to original systems. Newer additions on older Poulsbo homes often use different duct sizes or materials than the original system. The mismatch creates turbulence and debris accumulation at the transition points. We smooth those transitions or replace the mismatched sections so airflow stays consistent throughout the house.

FAQs About Air Duct Cleaning in Poulsbo
The odor usually comes from a disconnected or unsealed duct run in a damp crawlspace, not from the ducts themselves. In Poulsbo’s historic downtown and waterfront homes, marine air keeps crawlspaces humid year-round, and any gap in the return pathway pulls that musty air straight into your living space. Cleaning the ducts without sealing the crawlspace-side failures means the smell returns within weeks. We inspect with a camera first, quote the repair in writing, and seal with mastic so the system stops drawing from the wrong places. Call (361) 326-5060 for an exact quote – estimates are free.
Yes, every job starts with a video inspection of the trunk lines and key branch runs. In Poulsbo’s older housing stock, we focus especially on crawlspace transitions where disconnection and mold damage are most common. We show you the footage, explain what we found, and give you a written price for cleaning plus any needed repairs before touching anything. No surprises at the door.
We connect a Nikro negative-air machine to your trunk line, seal the registers, and use Rotobrush rotary tools to agitate debris loose while the vacuum pulls it into a HEPA-filtered containment system. Each vent gets individual attention. We photograph before and after. If we find disconnected or mold-damaged runs during the process, we stop, show you, and quote repair work separately. The whole process takes 3 – 5 hours for a typical Poulsbo home. Call (361) 326-5060 to schedule – estimates are free.
They’re quoted separately so you control the scope. Basic resealing of accessible joints is often included in the cleaning price. But if we find crushed, disconnected, or mold-damaged runs that need replacement, we quote that repair in writing before starting. Many Poulsbo homes need some repair to make cleaning worthwhile long-term. We won’t sell you a cleaning that we know will re-contaminate in a season.
Poulsbo’s marine climate, with 35+ inches of annual rainfall and humidity that rarely drops below 60%, accelerates mold growth in ductwork and crawlspaces. Homes with original duct materials or poor crawlspace ventilation typically need inspection every 3 – 5 years, and cleaning plus sealing when mold or disconnection appears. Newer construction with proper vapor barriers and sealed crawlspaces can go longer. The key is catching crawlspace-side failures before they spread through the whole system. Call (361) 326-5060 and we’ll assess your specific situation – estimates are free.
