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 Duct Sealing Across Ridgefield
We’re the crew Hollis Air Duct Cleaning sends to Ridgefield when conditioned air is bleeding into attics and crawlspaces instead of reaching the rooms where you actually live.

Dispatch and scheduling run through our Seattle office, but the van that pulls into your driveway is stocked for Ridgefield’s specific housing stock and the problems it produces. If your upstairs bedrooms won’t hold temperature or your energy bill keeps climbing with no explanation, call us at (361) 326-5060. We’ll give you a written price before we touch anything, and every seal we make carries our 365-Day Done Right Promise.
Why Hollis Air Duct Cleaning Is Ridgefield’s Preferred Duct Sealing Company
Hollis has been part of the Garrison Partners family since 2004. That’s a track record that predates most of the houses in Ridgefield’s biggest subdivisions. We’ve sealed ducts in Discovery Ridge during builder walk-throughs and in farmhouses near downtown where the original metal trunk lines have been leaking since the 1970s. Our technicians are background-checked, uniformed, and expected to behave by The Garrison Code: arrive inside the quoted window, price in writing, complete the job by the book, and leave the site clean.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues. When you schedule Duct Sealing with us, you get a written price before any work starts, and that number does not move at the door. If a seal fails within a year, we return and make it right at no charge, including a free second visit. That’s the 365-Day Done Right Promise, backed in writing on every job, not a vague “satisfaction guaranteed” line.
Air Duct Sealing in Ridgefield
Air Duct Sealing in Ridgefield is most often a repair job on builder-grade systems that have never been properly sealed from day one. The housing boom around Pioneer Canyon and Discovery Ridge produced thousands of homes with flexible duct runs stretched too far through attics, connected with tape or nothing at all at the collars, and register boots that leak at every transition. We find the gaps with camera inspection and pressure testing, then seal with mastic and mechanical fasteners where appropriate. Mastic is a thick, brush-on sealant that stays flexible and won’t dry out like tape; it fills gaps at trunk-to-branch joints, air handler connections, and around register boots where conditioned air escapes into wall cavities.
When Sealing Becomes a Structural Fix
Sometimes the duct itself is the problem, not just the seal. A flex run kinked over a truss or crushed by storage boxes in an attic won’t move air no matter how much mastic you apply. In those cases we replace the damaged section, then seal the new connections properly. We always inspect first so you’re not paying for sealing when the real fix is a re-run.
The One-Year Walk-Through Window
Many Ridgefield homeowners call us just before or just after the builder’s one-year warranty walk-through. That’s smart timing. Drywall dust and construction debris have had a year to settle into joints and seams, and any flex runs that were going to pull apart at the collar usually have by now. We document what we find with photos, which helps if you’re still negotiating with the builder.
Duct Sealing Services in Ridgefield
Duct Sealing Services in Ridgefield address the specific failure modes this market produces: fresh leaks in new construction, moisture damage in low-lying crawlspaces, and the occasional original metal system in older homes near downtown that needs seam sealing after decades of service. Our process starts with a visual and camera inspection of accessible ductwork, followed by a pressure test if indicated. We mark every leak, show you the photos, then apply mastic sealant and mechanical fasteners to restore the system’s designed airflow. For homes with Honeywell or Aprilaire filtration systems, we also verify that sealed ducts aren’t creating back-pressure that starves the filter.
Crawlspace Moisture Sealing
Properties near the Ridgefield National Wildlife Refuge and other low-lying areas sit on former floodplain where winter moisture collects in crawlspaces. Metal duct seams rust, mastic degrades before it cures fully, and tape simply falls off. We use moisture-resistant sealing compounds and recommend proper vapor barrier installation where the crawlspace environment demands it.
Attic Flex-Duct Repair and Seal
The long flex-duct runs common in Pioneer Canyon and Discovery Ridge attics sag between trusses, kink at turns, and separate at takeoff collars. We re-support the run, replace crushed sections, and seal all joints with mastic. The goal is designed airflow to every register, not just stopping the worst leak.

Trusted Brands We Service in Ridgefield
We stock parts and filtration products from Honeywell, Aprilaire, and Abatement Technologies, the same brands commercial crews specify. For Ridgefield homeowners, that means no waiting on special orders for common components. If your system uses a Honeywell media filter or an Aprilaire whole-house purifier, we verify compatibility after sealing so the restored airflow doesn’t overload the filter or bypass it entirely. Our Nikro negative-air equipment lets us test seal integrity under operating pressure before we leave. Fast turnaround matters here because many of these calls are warranty-related and time-sensitive.
Common Duct Sealing Problems We See in Ridgefield Homes
- Disconnected flex-run collars in Discovery Ridge and Pioneer Canyon attics. Builder crews often connect flex duct to takeoffs with tape alone. After a few seasons of thermal expansion and attic traffic, the collar slips. We find entire bedrooms dumping conditioned air into insulation.
- Drywall dust and construction debris clogging fresh joints. In Ridgefield’s 2000s-2020s housing stock, the ducts were used as construction trash chutes. Sealing over that debris traps it against the mastic and guarantees a future failure. We clean first, seal second.
- Rusted metal seams in crawlspaces near the Wildlife Refuge. Winter moisture from the Columbia River floodplain corrodes galvanized trunk lines. Tape won’t stick to rust; we grind, prime, and seal with compounds rated for damp environments.
- Undersized flex runs stretched to maximum length. When a duct is too small for the square footage and too long for the path, the increased static pressure pulls every joint apart. Sealing alone won’t fix it; we resize and re-run, then seal.
Pricing for Duct Sealing in Ridgefield, WA
A typical duct sealing job in Ridgefield runs $450 to $1,200 for a standard single-system home. Small repairs, a single disconnected collar or a few leaky register boots, fall at the lower end. Whole-system sealing on a large two-story with extensive flex-duct replacement reaches the higher end. What moves the number: accessibility (crawlspace vs. attic vs. finished basement), how much of the duct is flexible vs. metal, whether we’re cleaning construction debris before we seal, and if any sections need replacement rather than sealing.

FAQs About Duct Sealing in Ridgefield
Yes, frequently. Builder-grade flex-duct systems in these subdivisions are often sealed with tape or left unsealed at collars, and construction dust accelerates joint failure within the first two to five years. We recommend a camera inspection before the one-year builder warranty expires so any deficiencies can be documented. Call (361) 326-5060 to schedule; estimates are free.
Original metal trunk-and-branch systems near the historic downtown core, often with deteriorated seam tape, rust at low points, and register boots that have never been sealed to the floor or wall cavity. These systems can perform well for decades if properly sealed, but they rarely have been. The fix is methodical: replace failed tape with mastic, seal boots, and test.
Yes. Low-lying properties near the Ridgefield National Wildlife Refuge see crawlspace moisture that rusts metal seams and prevents mastic or tape from curing properly. Even a 2022 build can have failed seals if the crawlspace environment was never addressed. We use moisture-rated compounds in these conditions and advise on vapor barrier needs.
Camera inspection tells the story. If the duct is intact but leaking at joints, sealing is the fix. If it’s packed with drywall dust or construction debris, or if microbial growth is present from moisture, cleaning comes first and sealing follows. Sometimes both are needed. We show you the photos and explain what we’re seeing before quoting either service.
Most Ridgefield homeowners see measurable improvement in room-to-room temperature balance immediately, and energy savings typically follow within one to two billing cycles. The exact return depends on how badly the system was leaking and your heating and cooling usage patterns. The more immediate benefit is comfort: bedrooms that actually reach thermostat temperature and stop drawing dust from attic or crawlspace leaks.
