Call (361) 326-5060

We know the homes here. The newer subdivisions off 176th Street East with their heat-pump systems and long flex-duct runs. The older places near the Clover Creek greenbelt where metal ductwork from the 1970s is held together with failing tape. The marine air here doesn’t quit, and neither does the pollen that follows every dry spring spell. That combination finds every gap in your ducts. Our Duct Sealing team treats Clover Creek as a core service area, not an afterthought.

If your utility bills are climbing, rooms stay cold in winter or hot in summer, or you smell musty air when the heat pump kicks on, your ducts are likely leaking conditioned air into your attic or crawl space. Call (361) 326-5060. We’ll give you a written price before any work starts, and every seal is covered by our 365-Day Done Right Promise.

Why Hollis Air Duct Cleaning Is Clover Creek’s Preferred Duct Sealing Company

We’ve been part of the Garrison Partners family since 2004, and our Seattle office has handled Duct Sealing in Clover Creek long enough to know the patterns. After the first dry week in May, calls spike from homeowners who suddenly smell that musty, sweet odor when their heat pump switches to cooling. That’s pollen and biofilm baked onto the indoor coil and duct liner, a problem rarely seen in drier cities east of the Cascades. We know what to look for because we’ve sealed and cleaned hundreds of systems in this specific climate.

Our technicians are background-checked, uniformed, and expected to operate by The Garrison Code: arrive inside the quoted window, price in writing, complete the job by the book, leave the site clean. No exceptions. The price we write down before any work starts is the price you pay. It does not move at the door.

Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday to schedule. And every repair, including duct sealing, carries our 365-Day Done Right Promise in writing. If the seal fails within a year, we return and make it right at no charge, including a free second visit.

Duct Repair in Clover Creek

Duct Repair in Clover Creek addresses the physical damage that sealing alone won’t fix: crushed flex-duct in attics, disconnected joints in crawl spaces, corroded metal runs in older homes near the greenbelt, and rodent damage that we see more often in rural-style properties on the area’s edges. A typical repair runs $280 – $620 depending on accessibility and material. We use professional-grade equipment from Rotobrush and Nikro to access and restore damaged sections, and we always inspect the full system before quoting so you’re not paying for a band-aid when the whole run needs replacement.

Crushed or Collapsed Flex-Duct

In Clover Creek’s newer subdivisions, installers often ran flexible duct through tight attic spaces to reach distant rooms. Over years, storage boxes, maintenance traffic, or simply gravity compress these runs. A crushed flex-duct can’t move air efficiently and creates back-pressure that strains your heat pump. We replace the damaged section with properly supported duct and seal all joints with mastic.

Corroded Metal and Disconnected Joints

Older metal ductwork in Clover Creek’s rural properties suffers from decades of condensation cycling. The marine climate’s wet winters create moisture inside uninsulated metal runs, and by spring you’re looking at rusted-through sections or joints that have worked loose from thermal expansion. We cut out damaged metal, fabricate replacement sections, and seal with mastic and metal-backed tape rated for your system’s temperature range.

Air Duct Sealing in Clover Creek

Air Duct Sealing in Clover Creek closes the gaps, cracks, and failed joints that leak conditioned air into spaces you don’t heat or cool. In a typical Clover Creek home, we measure 15 – 30% air loss through duct leaks before sealing. After proper sealing with mastic and metal-backed tape, that drops to under 5%. A whole-home seal runs $450 – $850, with partial sealing of problem zones starting around $280. We also offer Air Duct Cleaning in Clover Creek as a bundled service, since sealing dirty ducts just traps debris inside.

Mastic Application for Permanent Seals

We don’t use standard duct tape, which dries and fails within a few years in Clover Creek’s humidity swings. We brush on water-based duct mastic, a thick sealant that remains flexible, fills irregular gaps, and bonds to metal, flex-duct, and fiberglass board. It takes longer to apply than tape, which is why cheaper quotes skip it. It also lasts the life of the duct system.

Pressure Testing After the Seal

After sealing, we run a duct blaster test to measure leakage in CFM25, cubic feet per minute at 25 Pascals of pressure. We show you the before and after numbers in writing. If the system doesn’t hit our standard, we find the remaining leaks and re-seal at no extra charge. That’s part of The Garrison Standard.

Trusted Brands We Service in Clover Creek

We stock parts and sealing materials from Aprilaire, Abatement Technologies, and Guardsman, the same filtration and air-quality brands used in commercial buildings across the Puget Sound region. For Clover Creek homeowners, this means no waiting on special orders for standard components. If your system uses Aprilaire media filters or Guardsman UV accessories, we can integrate sealing work with filter upgrades or air-purifier installation in the same visit. Our equipment roster also includes Rotobrush rotary brush systems and Nikro negative-air machines for jobs where sealing follows cleaning. We explain what each tool does and why we’re using it before we start.

Common Duct Sealing Problems We See in Clover Creek Homes

• Failed tape at flex-duct connections. The original installer used foil tape at flex-duct joints, and Clover Creek’s humidity cycles have cooked it brittle. We find this in nearly every home over 10 years old, especially in attics that hit 120°F during July dry spells.
• Leaky return air pathways in crawl spaces. Homes near the Clover Creek greenbelt often draw return air through unsealed floor cavities instead of dedicated ductwork. This pulls in crawl-space moisture and rodent droppings. We seal the pathway and install proper return duct where needed.
• Heat-pump coil cabinet leaks. The sticky pollen film that builds here works into gasket seams around indoor coils. When the system switches from heating to cooling, pressure changes force air through these gaps. We seal cabinet seams as part of comprehensive duct sealing.
• Retrofit ductwork in older rural homes. Properties on Clover Creek’s edges sometimes have ducts added piecemeal over decades, with mismatched materials and no consistent sealing standard. We map the full system, identify the worst leaks, and prioritize repairs that deliver the biggest efficiency gain for your dollar.
