We’ve worked in Newberg since long before it became a Portland bedroom community.

Why Bellows Air Duct & Vent Co. Is Newberg’s Preferred Duct Repair & Sealing Company
Newberg homeowners have called us back for 42 years because we show the price before we start and we stand behind the work. Our 90-Day Done Right Promise means if a seal fails or a repair doesn’t hold, we return at no charge. No paperwork, no arguing. That’s stamped on every job.
We answer our own phones, day or night. A live person, not a voicemail tree. When you’re pulling attic dust into your bedroom through a compromised return-air boot, you want someone who picks up.
Our camera inspection shows you the condition of your ducts before we touch a tool, and again when we’re done. Visual proof, not a claim. That’s especially important in Newberg, where fog-driven moisture damage can hide in junctions you can’t see from the crawl space entrance.
Ray Castillo has led this company since its founding in 1984, and our technicians still answer to him. The same values code, the same square deal.
Our Duct Repair & Sealing Services in Newberg
Duct Sealing
Leaky ducts in Newberg homes waste 20-30% of heated air before it reaches your rooms. We seal supply and return runs with mastic sealant and professional-grade reinforcement, pressure-testing afterward to verify the fix. In the Chehalem Valley’s damp climate, a proper seal also blocks the moisture infiltration that drives mold growth in mid-century ranch crawl spaces.
Flex Duct Repair
Flex duct, common in Newberg’s 1990s-2000s suburban builds and many retrofitted older homes, collapses, tears, or disconnects at junctions. We replace damaged sections with insulated flex rated for Pacific Northwest moisture exposure, secure them with mechanical fasteners plus mastic, and verify airflow balance room by room. In tight Newberg townhome crawl spaces, our compact flex-shaft equipment reaches mid-run damage that standard tools miss.
Metal Duct Repair
Original sheet-metal ductwork in Newberg’s early-1900s craftsman homes and post-WWII ranches corrodes at seams and develops whistling leaks where supports have sagged. We patch or replace sections, re-seal with mastic, and add access panels where none existed. No bait pricing: the estimate we give over the phone holds when we arrive.
Duct Insulation
Uninsulated or degraded duct insulation in Newberg’s unconditioned crawl spaces and attics creates condensation when warm heated air meets fog-cooled metal. We wrap supply runs with vapor-barrier insulation rated for high-humidity environments, sealing the envelope so your system doesn’t pay to reheat water droplets.
Mastic Sealant
Mastic is our standard for every Newberg seal job, not foil tape. The Chehalem Valley’s persistent winter fog keeps humidity near saturation for months, and tape adhesive fails where mastic remains flexible. We apply it with proper cure time accounted for, even when fog slows drying.
Air Leak Repair
Return-air leaks pull unfiltered crawl space air into your system, loading it with mold spores and organic debris. In Newberg’s damp conditions, this accelerates contamination dramatically. We locate and seal these leaks with smoke testing and camera verification, then show you the before-and-after.

Trusted Brands We Service in Newberg
We specify professional-grade equipment from Nikro, Honeywell, and Aprilaire, the same brands serious HVAC contractors use. Our Newberg service trucks stock Honeywell thermostatic wrap and mastic compounds formulated for high-humidity curing, so we’re not waiting on parts while your heat runs through a leaky system. Most repairs finish in one visit because we arrive prepared for the housing stock this city actually has.
Common Duct Repair & Sealing Problems We See in Newberg Homes
- Mastic that cures too fast in foggy winter air. Newberg’s Chehalem Valley fog keeps outdoor humidity near saturation from November through February. Mastic applied without accounting for this slow cure can skin over brittle and crack on the first heating cycle. We time application and verify flexibility before we leave.
- Alley-access homes with limited truck maneuverability. Historic downtown Newberg and dense townhome clusters often have alley loading or narrow side setbacks. Some contractors rush jobs in these tight quarters, missing mid-run leaks behind walls. Our compact Rotobrush flex-shaft systems let us work thoroughly where standard equipment won’t fit.
- Wine-harvest spores loaded into ducts before heating season. From mid-September through October, vineyard dust and crushed-grape organic matter spike in Newberg’s air. Homeowners who open windows during warm harvest days load this material into return-air systems right before the damp heating season begins. Sealing over contaminated ducts traps mold food inside. We clean before we seal.
- Original sheet-metal with no access panels. Newberg’s mid-century ranch homes frequently have duct runs through unconditioned spaces with no provision for inspection or repair. We cut proper access, do the work, and seal the opening to code, leaving your system maintainable.

FAQs - Duct Repair & Sealing in Newberg
Mastic sealant remains flexible and airtight where foil tape fails in Newberg’s prolonged high-humidity fog season. The Chehalem Valley’s winter humidity near saturation degrades tape adhesive within one to two heating seasons, while properly applied mastic lasts the life of the duct system. We use mastic on every Newberg job, backed by our 90-Day Done Right Promise. Call (844) 685-6342 for a free inspection.
We use Rotobrush flex-shaft systems and compact inspection cameras designed for confined spaces. In a historic downtown Newberg craftsman off Blossom Drive, we sealed a leaking flex-duct junction using Honeywell thermostatic wrap and mastic sealant, eliminating the whistling from a compromised return-air boot that was pulling attic dust into a bedroom. Standard equipment couldn’t reach it. If your Newberg home has tight access, we’ll tell you upfront whether our gear fits, no charge for the assessment. Call (844) 685-6342.
Duct sealing stops the musty smell if it’s caused by return-air leaks pulling damp crawl space air into your system, which is common in Newberg’s mid-century ranches with original sheet-metal ductwork. If the smell comes from mold already growing inside the ducts, sealing alone traps the problem. We camera-inspect first to identify the source, then clean if needed before we seal. The inspection is included in our estimate. Call (844) 685-6342.
Yes. October is the single most important pre-season window for duct work in Newberg. Sealing before November fog arrives prevents moisture-laden outside air from infiltrating your system all winter, reducing condensation, mold risk, and energy waste when your heat runs hardest. We prioritize Newberg appointments in September and October for this reason. Call (844) 685-6342 to book before the fog sets in.
Yes. We cut code-compliant access openings, complete the repair, and seal them with insulated access panels that meet current standards. Newberg’s early-1900s craftsman homes and post-WWII ranches frequently have original ductwork that was never designed for maintenance access. We leave the system inspectable for the next technician. Upfront pricing includes access creation, no surprise add-ons. Call (844) 685-6342 for a free estimate.
