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.

We’ve been dispatching crews to Duvall from our Seattle office long enough to know the valley’s quirks. The Snoqualmie Valley’s damp climate, the mix of 1990s subdivisions and older farmhouses along NE Big Rock Road, the way field mice move in after harvest – it all shows up in your vent line. Our technicians arrive uniformed, background-checked, and on time, with a written price before any work starts. No estimates that balloon once we’re inside.
Why Hollis Air Duct Cleaning Is Duvall’s Preferred Dryer Vent Cleaning Company
Hollis Air Duct Cleaning, founded in 2004 as part of the Garrison Partners family, has built its reputation on The Garrison Standard: written prices, written guarantees, and a 365-Day Done Right Promise that competitors rarely match in writing. In Duvall, that means something. Homeowners here aren’t looking for the cheapest bid; they’re looking for the bid they can trust.
Our crews know Duvall’s housing stock. We’ve cleaned vents in the two-story builds off Cherry Valley Road, the 1970s ranchers near Duvall Riverside Park, and the older farmhouses along the valley floor. We know which neighborhoods have flexible duct runs that sag between joists, and which ones have original metal vents that terminate under a deck instead of through the wall. That local knowledge saves time and prevents callbacks.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. When you schedule in Duvall, we arrive inside the quoted window, price the job in writing, and leave the site clean. If the work fails within a year, we return and make it right at no charge. That’s the 365-Day Done Right Promise, backed in writing on every job.
Dryer Vent Cleaning Company in Duvall
Dryer Vent Cleaning Company work in Duvall means more than vacuuming lint from a trap. We clean the full vent pathway from the back of your dryer to the exterior termination, using rotary brush systems and negative-air machines to dislodge packed lint, nests, and debris. Most Duvall homes need this every 12 – 18 months, though homes with long vent runs, multiple bends, or rodent activity may need it sooner.
A standard Dryer Vent Cleaning in Duvall runs $180 – $240 for a single-story home with a straightforward run. Two-story homes with longer duct paths, or jobs requiring vent rerouting or cap replacement, typically fall in the $260 – $340 range. We price by the system, not by the foot, and the number is written down before we start.
What the Cleaning Process Involves
We start with a visual inspection of the exterior hood and accessible ductwork. Then we use Rotobrush rotary agitation tools to scrub the interior walls of the vent line while a Nikro negative-air machine pulls the dislodged material out of your home. We finish by testing airflow and verifying the exterior damper opens fully under dryer operation.
When Duvall Homeowners Should Schedule
Call when drying time increases, the exterior hood barely opens, or you smell burning lint. In Duvall’s wet climate, damp lint packs harder and dries slower, so a vent that’s marginal in summer often fails in winter. Don’t wait for a second cycle every load.
Dryer Vent Inspection in Duvall
Dryer Vent Inspection in Duvall is where we often find the real problem. A camera run through the duct line reveals crushed sections, disconnected joints, improper terminations, and rodent damage that a surface cleaning would miss. In Duvall’s older valley-floor farmhouses and 1970s – 80s ranchers, we routinely find vents that terminate under a deck or into a crawlspace rather than through an exterior wall. That configuration keeps the lint pathway damp and rodent-accessible year-round.
A standalone Dryer Vent Inspection in Duvall costs $120 – $160. If you proceed with cleaning or repair, we credit the inspection fee toward the work. The inspection includes a written report with photos and a flat-price quote for any recommended repairs.
Camera Inspection Finds Hidden Damage
Our camera system shows every joint, sag, and obstruction in real time. In a 1990s two-story build, we might find a flexible duct sagging between joists, collecting lint at the low point. In a 1978 rancher off NE Big Rock Road, we might find a crushed metal run where it passes through the foundation. The camera doesn’t guess; it shows us exactly what we’re dealing with.
Inspection Before Real Estate Transactions
Duvall home buyers increasingly request dryer vent inspections before closing, especially on older valley-floor properties. A clean bill of health from Hollis, with photos and a written summary, gives buyers confidence and sellers documentation. The inspection pays for itself if it prevents a renegotiation or repair demand.
Trusted Brands We Service in Duvall
We stock and install dryer vent components from Guardsman, Aprilaire, and Abatement Technologies, plus pest-resistant vent hoods and rigid metal ducting that meets current code. For Duvall homeowners, that means fast turnaround without waiting for parts to ship. If your vent cap is damaged or your flexible duct needs replacement, we typically complete the repair same visit. We don’t use hardware-store foil or plastic flex – only rigid or semi-rigid metal that can handle the airflow and resist rodent damage. Our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines, the same tools commercial crews use, maintained and inspected by our technicians.
Common Dryer Vent Cleaning Problems We See in Duvall Homes
- Flexible duct runs sagging between joists in 1990s – 2000s two-story builds. These low points collect lint and moisture from Duvall’s damp air, creating a blockage that surface cleaning won’t fix without source removal. We replace the sagging section with properly supported rigid duct.
- Valley-floor crawlspace vents disconnected or crushed by rodent activity. After the first heavy fall rains, field mice move in from surrounding farmland and pack acorns against the vent hood. Lint escapes into the crawlspace instead of reaching the exterior – a hidden fire and mold risk we catch with camera inspection.
- Original metal vents in 1970s – 80s ranchers with separated seams. Decades of seasonal expansion and contraction open gaps in the duct wall, leaking lint into wall cavities and overworking the blower motor. We spot this with airflow testing and camera verification.
- Vent terminations under decks or below grade, trapping moisture. Duvall’s older farmhouses often have vents that never should have been routed this way. The damp pathway stays clogged year-round. We reroute above grade with a pest-resistant hood.

FAQs About Dryer Vent Cleaning in Duvall
Duvall’s Snoqualmie Valley location brings roughly 38 – 40 inches of annual rainfall and near-constant humidity, so lint packs damp and dense instead of staying loose and dry. Older Duvall homes also tend to have longer vent runs, more bends, and terminations that trap moisture under decks or in crawlspaces. Call (361) 326-5060 and we’ll inspect the full pathway to find the real restriction.
The signs are longer drying times, a hot dryer exterior, little or no airflow at the exterior hood, or lint collecting behind the dryer. But the only way to confirm a crushed or disconnected section inside a wall or crawlspace is with a camera inspection. Our Dryer Vent Inspection in Duvall includes a full camera run and written report. Call (361) 326-5060 to schedule.
Yes. We’ve cleaned and repaired vents in farmhouses along NE Big Rock Road and throughout the valley floor. These homes often have original metal ductwork, terminations under decks or into crawlspaces, and rodent activity that suburban builds don’t face. Our Dryer Vent Cleaning team brings the equipment and experience to handle these conditions properly.
We install Guardsman vent hoods, Aprilaire filtration accessories where applicable, and Abatement Technologies rigid metal ducting. For pest protection, we stock bird guards and rodent-resistant caps sized for Duvall’s common 4-inch vent lines. All components meet or exceed local code requirements.
Most Duvall homes need dryer vent cleaning every 12 – 18 months. Homes with long runs, multiple bends, or frequent laundry loads should schedule annually. Valley-floor properties with crawlspace vents or known rodent activity may need inspection every fall before the rainy season. Call (361) 326-5060 and we’ll recommend a schedule based on your specific home.
