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 Hazel Dell
Air duct cleaning in Hazel Dell typically runs $350 – $650 for a full residential system, and most jobs are scheduled within two to three business days. We’re the Air Duct Cleaning crew that serves Hazel Dell from our Seattle dispatch office, with technicians who know the difference between a 1950s ranch off Hazel Dell Avenue and a 1970s split-level near NE 99th Street. That local knowledge matters because the ductwork in this part of the Vancouver lowlands faces problems you won’t find in drier inland markets. Call (361) 326-5060 for a free estimate, and we’ll give you a written price before any work starts.
Why Hollis Air Duct Cleaning Is Hazel Dell’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our reputation in Hazel Dell is built on showing up when we said we would, pricing in writing, and leaving the site clean. Our technicians are background-checked and uniformed, and phones are answered by a live person 24 hours a day, 7 days a week. Roy Castellanos leads this operation, and The Garrison Standard he follows means no estimate balloons once the van is in your driveway.
Dispatch and scheduling are coordinated from our Seattle office, but crews serve Hazel Dell locally and understand the area’s specific challenges: the high water table, the marine climate that keeps indoor humidity above 60% through winter, and the post-WWII housing stock with ductwork now pushing 60 years old. When a Hazel Dell homeowner calls after a crawlspace flood, we know what to look for and how to document it so an insurer can follow the logic.
Air Duct Repair in Hazel Dell
Air Duct Repair in Hazel Dell often means addressing corrosion, collapsed flex runs, or rodent damage in the original duct systems that still serve most of the area’s homes. Because Hazel Dell’s lowland water table sits close to the surface, crawlspace duct runs in the 1970s-era subdivisions off NE 99th Street corrode from the outside in – meaning rust-through that isn’t visible from inside the duct is the deciding factor between cleaning and replacement. A typical repair in Hazel Dell runs $200 – $500 for localized fixes, while full section replacement on older galvanized or flex duct can reach $800 – $1,500 depending on accessibility and material.
When Repair Beats Replacement
Surface mold on galvanized steel trunk lines, loose joints at plenum connections, and minor corrosion spots that haven’t penetrated the duct wall can all be cleaned, sealed, and returned to service. We use Nikro negative-air machines to contain debris during the process, then seal with mastic rated for HVAC applications. The key is verifying the duct’s structural integrity before committing to cleaning.
When Replacement Is the Only Safe Option
Waterlogged flex duct cannot be dried at its core. Saturated insulation traps moisture against the inner liner, and mold returns within weeks even after aggressive cleaning. Rust-through on galvanized steel, visible from the exterior of the pipe, means the metal has lost its integrity and will continue to degrade. We document both conditions with date-stamped photos and moisture readings at each joint.
Ductwork Cleaning in Hazel Dell
Ductwork Cleaning in Hazel Dell addresses the debris buildup, mold spores, and dust-mite colonies that thrive in this area’s persistently humid climate. With annual rainfall near 40 inches and indoor humidity frequently above 60% in winter, Hazel Dell’s marine climate creates ideal conditions for biological growth inside ductwork. A typical full-system cleaning in Hazel Dell runs $350 – $650, with antimicrobial fogging adding $75 – $150 when moisture remediation is indicated. Commercial systems start around $800 and scale with square footage and access complexity.
Residential System Cleaning
Our rotary brush systems from Rotobrush agitate debris from duct walls while Nikro negative-air machines pull it out of your home entirely, not just redistribute it. We clean supply ducts, return ducts, and the main trunk line, then inspect with a video camera so you see what we saw. In Hazel Dell’s older ranches, we often find that original galvanized runs have internal corrosion that traps debris brush systems alone can’t reach.
Post-Flood and Moisture Remediation
After water intrusion, cleaning must be paired with moisture remediation to prevent immediate recontamination. We bring in commercial dehumidification, apply antimicrobial fogging with products from Abatement Technologies, and take moisture readings at multiple points to verify the system is truly dry before we sign off. Without this step, you’re cleaning mold that will be back in thirty days.
Trusted Brands We Service in Hazel Dell
We carry equipment and filtration products from Honeywell, Aprilaire, and Abatement Technologies – the same brands commercial crews specify – and we stock common replacement parts so Hazel Dell customers aren’t waiting on a warehouse shipment. Our rotary brush systems are from Rotobrush, negative-air machines from Nikro, and antimicrobial treatments from Abatement Technologies. When your system needs a new filter housing or an upgraded media filter, we can source Honeywell and Aprilaire components with turnaround that keeps your job moving. We don’t upsell brands; we match the right equipment to what your ductwork actually needs.
Common Air Duct Cleaning Problems We See in Hazel Dell Homes
- Collapsed flex duct in 1970s subdivisions. The original flex runs feeding bedrooms in homes off NE 99th Street and Hazel Dell Avenue have often been crushed by decades of foot traffic in attics or compressed by insulation shifts. Airflow drops, rooms stay cold, and homeowners blame the furnace when the real problem is a duct that has pancaked flat.
- Hidden rust-through on crawlspace galvanized steel. Because corrosion starts on the exterior of the pipe where the high water table keeps moisture constant, the interior can look passable on camera while the metal is paper-thin. We check the exterior condition on every crawlspace job in Hazel Dell.
- Mold and mildew from persistent humidity. Indoor humidity above 60% through winter months means duct interiors never fully dry. We regularly find active mold growth on the downstream side of evaporator coils and inside return plenums in Hazel Dell homes that haven’t had ducts cleaned in five-plus years.
- Rodent intrusion in unsealed crawlspace systems. The same loose joints that leak conditioned air also admit mice and rats. We find nesting debris, droppings, and chewed flex in crawlspace runs more often in Hazel Dell’s older housing stock than in newer, tighter construction in surrounding areas.

FAQs About Air Duct Cleaning in Hazel Dell
It depends on what the water touched and for how long. Galvanized steel trunk lines can often be cleaned, dried, and fogged if the water was clean and the metal hasn’t rusted through. Flex duct that has been saturated must be replaced – the inner liner and insulation cannot be dried at the core, and mold will return within weeks. We run a camera inspection and take moisture readings at each joint to make the call, then document both conditions separately for your insurer. Call (361) 326-5060 and we’ll schedule an assessment.
We provide date-stamped photos, moisture readings at each joint, and a written report distinguishing cleanable conditions from those requiring replacement. One or two photos with no readings gives an adjuster nothing to approve; we give them a complete file. Our techs follow The Garrison Code on every job: arrive inside the window, price in writing, complete the job by the book, and leave the site clean. That discipline extends to documentation that holds up under review.
Hazel Dell sits in the Vancouver lowlands near the Columbia River with a high water table that keeps crawlspace soil moist year-round. Ducts in Camas and Battle Ground, at higher elevation with better drainage, don’t sit in perpetually damp conditions. In Hazel Dell, galvanized steel corrodes from the exterior where the camera can’t see it, which is why we always check the outside of the pipe on crawlspace jobs here.
We schedule most Hazel Dell assessments within two to three business days, and we prioritize homes with active water intrusion or no heat due to duct damage. Cleaning cannot begin until the space is dry – running brushes through wet ductwork spreads contamination and damages equipment. We bring commercial dehumidification when needed to speed that timeline. Call (361) 326-5060 to get on the schedule.
Yes. Our cleaning protocols follow NADCA ACR, the standard for HVAC system restoration, and our documentation format aligns with what insurance adjusters expect to see from certified restoration work. The 365-Day Done Right Promise backs every job: if the work fails within a year, we return and make it right at no charge, including a free second visit. We put that in writing on every Hazel Dell job.
