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 Pacific
Duct sealing in Pacific typically runs $450 – $850 for a whole-home system, and most jobs are completed in a single visit. We dispatch from our Seattle office and keep Pacific inside our regular service window, which means we’re not asking you to wait for a crew driving up from Tacoma or down from Everett. Call (361) 326-5060 for a written estimate before any work starts.
We’ve sealed ducts in the river-flat mobile parks off Stewart Road where flexible under-floor runs sag and separate every winter, and we’ve worked the 1960s ranch ramblers near Pacific Avenue where original fiberglass ductboard has turned brittle and porous after sixty years of White River valley temperature swings. That local familiarity matters because Pacific’s housing stock isn’t uniform, and the fix that works in a Milton hillside split-level won’t hold in a Pacific manufactured home with six inches of crawl space. Our Duct Sealing team carries the tools for both.
Why Hollis Air Duct Cleaning Is Pacific’s Preferred Duct Sealing Company
Pacific homeowners know the difference between a crew that shows up uniformed and accounted for and one that rolls in unmarked and unprepared. We’ve been part of the Garrison Partners family since 2004, and our technicians operate under The Garrison Code: arrive inside the quoted window, price in writing before touching equipment, finish by the book, leave the site clean. No exceptions.
Our phones are answered by a live person 24 hours a day, 7 days a week. That matters when you’re trying to schedule around a shift at one of the distribution centers near the Port of Tacoma corridor and can’t afford to miss a callback window. We background-check and uniform every technician, and you’ll know who’s arriving before they knock.
Every duct sealing job carries our 365-Day Done Right Promise in writing. If the seal fails within a year, we come back and make it right at no charge, including a free second visit. That’s not a verbal assurance; it’s printed on your invoice.
Duct Sealing Services in Pacific
Duct Sealing Services in Pacific address the leaks, gaps, and separated joints that let heated and cooled air escape before it reaches your rooms. In this market, we see two distinct problem profiles: older ranches with original metal ductwork that has shaken loose at the seams from decades of valley wind exposure, and mobile homes with flexible duct runs that detach from plenums when rodents or moisture compromise the connections. A typical whole-home duct sealing in Pacific runs $450 – $850 depending on system size and accessibility.
Leak Detection and Pressure Testing
We start with a duct blaster test or calibrated pressure measurement to quantify exactly how much air you’re losing. In Pacific’s older homes, we regularly find 25 – 35 percent leakage, which means a quarter of what your furnace or heat pump generates never makes it to the registers. The test gives us a baseline and lets us prove improvement when we’re done.
Mastic and Mechanical Sealing
We seal accessible joints with UL-181 rated mastic, a water-based compound that remains flexible and won’t crack like tape. For buried or concealed runs, we use aerosol-based duct sealing where appropriate. Every connection gets mechanical reinforcement where code allows, not just a smear of goop that dries and fails by next season.

Duct Insulation in Pacific
Duct Insulation in Pacific protects against the temperature loss that happens when your conditioned air travels through unconditioned spaces, particularly the crawl spaces and attics common in this city’s older housing stock. Pacific’s cold, damp winters and warm, dry summers create a wider seasonal spread than many Puget Sound cities, which means uninsulated ductwork works harder year-round. A typical duct insulation job in Pacific runs $600 – $1,200 for a full system wrap, depending on linear footage and R-value needed.
Crawl Space and Under-Floor Wrap
Pacific’s river-flat homes, especially the manufactured housing along the White River, often have duct runs suspended in crawl spaces that flood seasonally or hold persistent moisture. We use foil-faced fiberglass or closed-cell wrap rated for damp locations, sealed at every seam to prevent condensation buildup that leads to mold and degraded indoor air quality.
Attic Runs and Riser Insulation
Ranch ramblers in the Stewart Road and Pacific Avenue areas frequently have trunk lines in attics that hit 120 degrees in July and drop below freezing in January. Proper insulation with vapor barrier slows that heat transfer and reduces the temperature swing your equipment must overcome. We size the R-value to what your system actually needs, not what a one-size-fits-all kit provides.
Trusted Brands We Service in Pacific
We carry professional-grade equipment and materials from Nikro, Honeywell, and Aprilaire, the same brands commercial crews specify for distribution facilities along the I-5 corridor. For Pacific homeowners, that means we don’t need to special-order basic fittings or wait on a parts run from Seattle. Our vans stock mastic, mechanical fasteners, and insulation wrap sized for residential ductwork, and our technicians are trained on the installation standards each manufacturer requires to honor its specifications. When we seal or insulate your system, we’re using the materials your ductwork was designed to work with, not hardware-store substitutes that degrade in Pacific’s damp crawl spaces.
Common Duct Sealing Problems We See in Pacific Homes
- Valley wind vibration damage. The dry, gusty White River valley winds that sweep through Pacific’s open farmland rattle exposed ductwork and loosen metal seam connections over time. We find separated longitudinal seams in attics and garages where decades of vibration have undone the original factory seal.
- Flooded crawl space separation. Mobile homes in Pacific’s river-flat parks experience seasonal moisture and occasional flooding that corrodes metal straps and causes flexible duct to sag and pull free from boots. The resulting gaps pull musty, rodent-affected air directly into the living space.
- Original ductboard deterioration. The 1960s and 1970s ranch homes near Pacific Avenue and surrounding neighborhoods were built with fiberglass ductboard that becomes brittle and porous after fifty-plus years. The resin binder breaks down, and the board itself acts like a filter, leaking conditioned air through its walls.
- Post-remodel disconnection. Pacific’s working-class housing stock has seen generations of homeowner modifications, additions, and DIY furnace replacements. We regularly find abandoned duct stubs left open, new registers connected with flex duct crimped to half its diameter, and return plenums cobbled together with duct tape that failed years ago.
Pricing for Duct Sealing in Pacific, WA
Whole-home duct sealing in Pacific typically costs $450 – $850. Duct insulation runs $600 – $1,200 for a full system. What moves you inside those ranges is straightforward: total linear footage of ductwork, how much is accessible versus buried in walls or under structure, and whether we need to bring in aerosol sealing equipment for ducts that can’t be reached by hand.
We do not quote per-vent or use teaser prices that balloon once we’re inside. You get one flat price per system, agreed in writing before any work begins. That price includes the pressure test to establish your leakage rate, all materials and labor, and the post-seal verification to prove we hit the target. Estimates are free, and there’s no charge for us to look at your system and give you a number you can count on. Call (361) 326-5060 to schedule.

FAQs About Duct Sealing in Pacific
We typically schedule Pacific homeowners within 3 – 5 business days, and our dispatch from the Seattle office keeps travel time predictable. Call (361) 326-5060 to check current availability.
Yes, we seal ducts throughout Pacific’s river-flat mobile home communities, the ranch neighborhoods near Pacific Avenue, and newer construction near the industrial corridor. The flexible duct and low-clearance crawl spaces common in Pacific’s manufactured housing are a regular part of our work.
We do not offer after-hours emergency dispatch for duct sealing, as it is a scheduled maintenance and repair service rather than an urgent safety issue. If you have a complete HVAC failure, we recommend contacting your heating and cooling contractor first; we can seal the ductwork once the mechanical system is stabilized.
Pacific pricing is comparable to Auburn and Federal Way, though mobile homes with under-floor flexible duct can run toward the higher end of our $450 – $850 range due to limited access. Homes in Puyallup’s hill neighborhoods with full basements sometimes seal for less because the ductwork is exposed and reachable.
Every duct sealing job is covered by our 365-Day Done Right Promise in writing. If any sealed joint fails, any mastic cracks, or any connection separates within one year of service, Hollis returns and makes it right at no charge, including a free second visit. The warranty is tied to the work, not the homeowner, so it transfers if you sell.
