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 Bremerton
Duct sealing in Bremerton typically runs $400 – $900 for a whole-house system, and most jobs are completed in a single visit after we inspect with a camera. If you’re losing heated air into a damp crawlspace or pulling dust through gaps in your supply runs, sealing stops both the energy waste and the contamination at the source. Call (361) 326-5060 for a free written estimate before any work starts.
We serve Bremerton from our Seattle office, with crews that know the local housing stock and the specific problems this marine climate creates. Whether you own a 1920s bungalow in Manette, a mid-century ranch in East Bremerton, or a place out toward the Seabeck Highway with a wood stove and a gravel drive, we’ve worked on duct systems like yours. Bremerton’s combination of older galvanized ductwork, high winter humidity, and rural-edge dust loading means sealing here isn’t a copy-paste job from a drier climate. We inspect first, price in writing, then seal with mastic and mechanical fasteners that hold up to this environment.
Why Hollis Air Duct Cleaning Is Bremerton’s Preferred Duct Sealing Company
Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004. In Bremerton, that track record matters because so many homes here have duct systems that haven’t been touched in decades. Our technicians are background-checked, uniformed, and expected to follow The Garrison Code on every job: arrive inside the quoted window, price in writing before touching anything, complete the work by the book, and leave the site clean.
Our 365-Day Done Right Promise covers every duct sealing job in writing. If the seal fails within a year, we return and make it right at no charge, including a free second visit. No negotiation, no runaround. Phones are answered by a live person 24 hours a day, 7 days a week, so you’re not waiting through a voicemail loop when you’ve got a question about your job.
We know Bremerton’s neighborhoods. We’ve sealed ducts in the tight crawlspaces under downtown bungalows, in the original ranch homes off Wheaton Way, and in newer construction out McCormick Woods way. That local familiarity means we show up with the right materials for your specific duct type, not a generic kit.
Duct Insulation in Bremerton
Duct Insulation in Bremerton addresses a problem forced-air homeowners here feel every winter: heat bleeding out of supply runs before it ever reaches the registers, especially when those runs pass through unconditioned crawlspaces or attics in the damp cold. In Bremerton’s marine climate, where heating season stretches 7 – 8 months and outdoor humidity regularly hits 80 – 90% in winter, uninsulated or poorly insulated ducts don’t just waste money. They create condensation on the metal that drips into surrounding structure and promotes mold. A typical duct insulation job in Bremerton runs $600 – $1,400 depending on linear footage, accessibility, and whether we’re reinsulating after cleaning out degraded old wrap.
When Insulation Beats Sealing Alone
Some Bremerton homeowners call us for sealing when the real problem is temperature drop across a long crawlspace run. If your supply air leaves the furnace at 110°F and arrives at the bedroom register at 82°F, the gap is likely uninsulated or waterlogged insulation, not just leaks. We check with a temperature gun before recommending work.
Marine-Climate Insulation Choices
In Bremerton’s high-humidity environment, we use closed-cell foam or foil-faced fiberglass with sealed seams, not the standard wrap that soaks up crawlspace moisture and collapses in three years. The right material here has to repel water vapor, not just slow heat transfer.
HVAC Duct Sealing in Bremerton
HVAC Duct Sealing in Bremerton closes the gaps, disconnected joints, and deteriorated seams that let heated air escape into crawlspaces, attics, and wall cavities while pulling dusty, damp unconditioned air back into your breathing space. In a typical Bremerton home with original or lightly updated galvanized ductwork, we commonly find 15 – 30% air loss through leaks before we start. Sealing that system with mastic compound and mechanical reinforcement usually runs $400 – $900 for a whole-house job, with larger or multi-zone systems occasionally reaching $1,200 if we need to access extensive crawlspace runs.
Camera Inspection Before Seal
We run a camera first. In Bremerton’s older housing stock, especially the mill-era bungalows in Manette and downtown, we’ve found standing water in low duct runs and ash-silica paste in rural properties that would trap contamination behind a fresh seal. Sealing over that is malpractice. We show you what the camera sees, then price the full job.
Post-Seal Verification
After sealing, we pressure-test or use smoke pencil verification to confirm the leaks are actually closed. A sealed duct system in Bremerton should hold its pressure and stop pulling crawlspace air. We don’t guess, and we don’t call it done until we’ve measured.
Trusted Brands We Service in Bremerton
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation inside duct walls, Nikro negative-air machines for controlled debris extraction, and filtration and sealing products from Honeywell, Aprilaire, and Abatement Technologies. For Bremerton homeowners, this means we stock parts and materials suited to the forced-air systems common in local housing, from older furnaces in downtown bungalows to newer heat pumps in McCormick Woods. We don’t order parts from across the water and make you wait. Our crews carry the mastics, tapes, and insulation wraps that hold up in this humidity, so most sealing jobs finish same-day once inspection is complete.
Common Duct Sealing Problems We See in Bremerton Homes
- Moisture-saturated duct in unsealed crawlspaces. In Manette and downtown Bremerton bungalows, we regularly find original under-floor duct runs holding standing water after fall and winter rains. Sealing these without drying and cleaning first just traps mold-friendly conditions behind the mastic.
- Ash-and-silica buildup in wood-heated rural properties. Out toward the Seabeck Highway and Chico corridors, wood stoves and unpaved drives load ducts with fine ash and road dust that marine humidity cements to duct walls. Tape or mastic applied over that layer fails within a season.
- Disconnected flex duct at furnace transitions. In 1960s – 80s East Bremerton ranches, original flex duct has often sagged, torn, or pulled loose at the plenum. The gap looks like a seal job but usually needs replacement of the degraded flex before new connections hold.
- Leaky shop and outbuilding supply runs. Rural Bremerton properties often have ducts serving detached shops or garages that pull dust straight off gravel pads. Standard residential sealing doesn’t address the exterior-grade exposure these runs face.
Pricing for Duct Sealing in Bremerton, WA
Whole-house duct sealing in Bremerton typically costs $400 – $900. Duct insulation runs $600 – $1,400. Larger homes with extensive crawlspace access, multiple zones, or detached outbuilding systems can reach $1,200 – $1,800. What moves the price: linear footage of duct, accessibility (tight crawlspaces take longer), condition of existing ductwork, and whether we need to clean before sealing.
We give one flat price per system, agreed in writing before any work starts. No per-vent pricing. No add-ons at the door. You’ll see the camera footage, hear our recommendation, and get a written number. If the scope doesn’t change, the price doesn’t move. Free estimates. Call (361) 326-5060.

FAQs About Duct Sealing in Bremerton
Every 2 – 3 years for properties on gravel or unpaved roads with wood heat, compared to the 4 – 5 year interval typical for filtered, paved-road homes. The silica dust, pollen, and ash loading in rural Bremerton accelerates buildup and degrades seals faster. Call (361) 326-5060 and we’ll set an inspection schedule based on your specific road surface and heating type.
Yes, but only after we address the moisture source and dry the existing duct. Sealing over wet galvanized duct traps water and guarantees mold. We typically recommend a cleaning and drying pass, possibly with a dehumidification period, before mastic application. The written price includes whatever preparation your specific crawlspace needs.
It depends on the duct’s construction and exposure. Residential-grade flex or sheet metal in a detached shop often needs exterior-rated sealing and insulation, not standard interior mastic. We price these separately after inspection, and we’ll tell you honestly if the system is too degraded for sealing to make sense.
It stops heated air from leaking into crawlspaces and attics, reduces the dust and humidity pulled back into living space through gaps, and lets your furnace reach set temperature without overworking. In Bremerton’s long heating season, that efficiency gain pays back faster than in milder climates. Most homeowners notice more even temperatures room-to-room within days.
Because a blocked or leaking dryer vent creates backpressure that can compromise nearby duct seals and introduces lint and moisture into the same crawlspace where your supply runs live. In Bremerton’s humid environment, that moisture load matters. We check it as part of a complete assessment, and we’ll note any issue without pushing unnecessary work.
