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 Suquamish
Suquamish sits on the western shore of Agate Passage, where the Olympic Mountains catch the rain and the Douglas firs grow thick enough to block afternoon light. That combination, damp soil and dense shade, is hard on ductwork. We’re the Duct Sealing in Suquamish crew that local homeowners call when their utility bills spike in January or when a crawl space starts smelling musty every time the furnace kicks on. Our technicians drive from the Seattle office, typically arriving inside a two-hour window for scheduled appointments across the Port Madison Reservation and the neighborhoods along South Sandy Hook Road. If your ducts are leaking heated air into an uninsulated crawl space or pulling fiberglass particles back into your living room, we’ll find the gaps and seal them properly. Call (361) 326-5060 for a free written estimate.
Why Hollis Air Duct Cleaning Is Suquamish’s Preferred Duct Sealing Company
We’ve been working in Kitsap County long enough to know which Suquamish homes were built with original galvanized ducting from the 1960s and which subdivisions went up in the 1990s with flexible duct that squirrels have since chewed through. That matters because the repair approach changes. Our Duct Sealing team carries mastic rated for marine-climate humidity, not the thinner compounds that crack after two wet winters. Suquamish customers leave reviews mentioning specifically that we showed up in the window, priced the job before opening a toolbox, and left the crawl space cleaner than we found it. Our phones are answered by a live person 24 hours a day, 7 days a week, no callback queues, which matters when you’re trying to schedule around a ferry commute or tribal council hours. Roy Castellanos built this operation on The Garrison Standard: arrive inside the window, price in writing, complete the job by the book, leave the site clean.
Air Duct Sealing in Suquamish
Air Duct Sealing in Suquamish means closing the gaps, seams, and disconnected joints in your forced-air system so the heat you pay for actually reaches your rooms instead of dissipating into your crawl space, attic, or wall cavities. Most Suquamish homeowners don’t realize their ducts are leaking until they notice one bedroom stays cold, their electric bill jumps 30% in a wet November, or they spot condensation dripping from a ceiling register. A typical whole-system seal in Suquamish runs $450 – $850 for a single-family home up to 2,500 square feet, with larger homes or systems requiring extensive crawl-space work ranging up to $1,200.
How We Find the Leaks
We pressurize your duct system and use a calibrated smoke pencil to trace every escaping stream of air. In Suquamish’s older homes near Suquamish Way, we regularly find the worst leaks at the plenum connection and at the flexible duct elbows where decades of vibration have loosened the zip ties.
What the Sealant Actually Does
We apply water-based duct mastic with a reinforced mesh tape at joints, then seal register boots to drywall with latex caulk. The mastic remains slightly flexible, which matters in Suquamish because temperature swings between your 55-degree crawl space and 120-degree attic ductwork cause expansion and contraction that rigid tapes can’t survive.
Duct Sealing Services in Suquamish
Duct Sealing Services in Suquamish cover everything from spot repairs on a single disconnected run to full-system restoration for homes where the original ductwork has corroded through. Because Suquamish’s housing stock includes so many mid-century builds with galvanized steel ducts, we often find pinhole rust and separated seams that simple tape won’t fix. Those jobs require cutting out damaged sections and splicing in new duct with proper collars and mechanical fasteners, then sealing the joints. A spot repair on one or two runs typically costs $180 – $340; partial system replacement with sealing runs $600 – $950.
Crawl Space and Moisture Considerations
Suquamish’s year-round humidity means crawl spaces stay damp. We frequently find fiberglass duct liner that’s become a mold substrate. When we encounter that, we remove the contaminated liner, seal the bare metal, and recommend an antimicrobial treatment with Guardsman products before we close up.
Attic Ductwork in Fir-Shaded Homes
Homes tucked under the dense Douglas fir canopy, especially along the slopes above South Kingston Road, see attic ducts that never fully dry in winter. We seal those systems with extra attention to the vapor barrier, because a sealed but uninsulated duct in a cold attic will sweat and create new moisture problems.

Trusted Brands We Service in Suquamish
We carry mastic, tapes, and mechanical fasteners from Abatement Technologies and Aprilaire on every Suquamish job, plus replacement duct sections and register boots sized for the older construction common here. Our vans stock Rotobrush rotary brush systems for the cleaning pass that should precede any seal, because sealing dirty ducts just traps debris. If your system needs filtration upgrades after sealing, we install Aprilaire media air cleaners and Guardsman antimicrobial treatments. Keeping parts on the van means most Suquamish jobs finish in one visit. We don’t order materials and make you wait.
Common Duct Sealing Problems We See in Suquamish Homes
- Corroded galvanized plenums in mid-century ranches. The original sheet metal rusts from the inside out where condensation pools. We cut out the damaged section, fabricate a replacement, and seal it with mastic rated for continuous moisture exposure.
- Disconnected flexible duct in 1990s subdivisions. The plasticized inner liner separates from the collar when cable ties degrade. We reattach with permanent band clamps and seal the joint properly, not with duct tape that will fail in six months.
- Squirrel and raccoon damage in crawl spaces near the waterfront. Animals tear flexible duct to reach the warmth. We replace chewed sections with rodent-resistant rigid duct where accessible, then seal all penetrations.
- Mold-saturated fiberglass liner in fir-shaded homes. The dense tree canopy keeps crawl spaces cool and damp year-round. We remove contaminated liner, seal the metal core, and treat with antimicrobial before reinsulating.
Pricing for Duct Sealing in Suquamish, WA
Honest pricing means you know the range before we start. For a typical Suquamish single-family home, duct sealing runs $450 – $850. Smaller spot repairs start around $180. Extensive work on larger homes, or systems requiring partial duct replacement, can reach $1,200. What moves the number: how much of your system is accessible (crawl space vs. finished basement), whether we need to remove contaminated insulation, and if the original duct material is salvageable or needs replacement. We don’t price per vent or per linear foot, because that’s how bills balloon. We quote one flat price per system, agreed in writing before any work starts. Estimates are free. Call (361) 326-5060.

FAQs About Duct Sealing in Suquamish
Duct sealing in Suquamish typically costs $450 – $850 for a standard home, which sits right in line with Poulsbo and Silverdale pricing. The difference is usually crawl space accessibility, not geography. Suquamish’s older homes on tighter lots sometimes require more labor to access ducts, which can push complex jobs toward the higher end. Call (361) 326-5060 for an exact quote on your home.
