That’s how we’ve operated for over 14 years. Call (844) 685-6342 to schedule your free estimate.
Why Bellows Air Duct & Vent Co. Is Opportunity’s Preferred Duct Repair & Sealing Company
Opportunity homeowners call us back because we show up when we say we will. We’ve repaired ductwork on the same streets our technicians have driven for decades, from the older ranches near Greenacres to the mid-century builds off Dishman Mica Road. Our customers here tend to stay put, and they remember which contractors earned their trust.
Our reviews from Opportunity customers consistently mention the camera inspection. They like seeing the before-and-after footage, especially after smoke season when that gray-brown film is coating everything. No one has to take our word for it.
Response time to Opportunity averages under 60 minutes during business hours. We’re already in the Spokane Valley for calls in Veradale and Spokane Valley proper, so 99206 is never a haul for us.
We also understand the local building patterns. The mixed systems in Opportunity, where a 1950s metal trunk feeds into flex-duct branches from a 2005 kitchen remodel, require a different approach than new construction. We’ve sealed enough of these transitions to know where they fail.
Our Duct Repair & Sealing Services in Opportunity
Mastic Sealant Application
Mastic is the only sealant we trust for Opportunity’s conditions. The dry heat here, regularly hitting the upper 90s in July and August, turns ordinary duct tape brittle within a single season. We find hanging, yellowed patches on nearly every home where a homeowner tried a DIY fix. Our mastic application, paired with mechanical fasteners, cures to a flexible, permanent bond that holds through smoke season and deep freeze alike. For homes that ran their systems during the 2020 or 2021 smoke events, we often need two or three passes to clear the bonded particulate before mastic will adhere properly. That’s not upselling. That’s what the work actually requires in this valley.
Metal Duct Repair
The original trunk-and-branch systems in Opportunity’s 1940s through 1970s housing stock are built from galvanized sheet steel that can last a century if maintained. The problem is the seams. Decades of thermal expansion in our hard winters, combined with smoke-film buildup that traps moisture against the metal, corrode joints and create pinhole leaks. We patch with matching 26-gauge galvanized steel and seal with mastic, not aerosol. Aerosol sealants won’t bond to smoke-filmed metal. We’ve tested it. Mechanical repair is the only repair that holds here.
Flex Duct Repair
On a 1950s ranch home in the Greenacres neighborhood, we found a flex-duct branch from a 2015 remodel had torn at the joint, pulling unfiltered smoke-season air into the system. We sealed the tear with Rotobrush mastic and patched the damaged metal trunk with 26-gauge galvanized steel and mastic, restoring leak-free operation. This is typical of what we see in Opportunity: flex-duct transitions in remodels collapse if not properly supported, creating accumulations that trap moisture and ash. The fix is straightforward if you catch it early. We check support straps, joint integrity, and insulation condition on every flex-duct call.
Duct Insulation
Uninsulated or degraded duct insulation in Opportunity costs you money from October through March. Our sustained heating season means every degree of lost thermal energy hits your Avista bill directly. We replace insulation with materials rated for our temperature swings, paying special attention to crawl space and attic runs where Spokane Valley wind infiltration accelerates heat loss. Proper insulation also reduces condensation that can compound smoke-film accumulation problems.

Trusted Brands We Service in Opportunity
We carry Rotobrush and Nikro equipment on every truck, and we stock mastic and fasteners from Abatement Technologies for Opportunity jobs. That matters when you’re dealing with smoke-season damage that can’t wait for a parts order. Our technicians don’t make two trips because they didn’t have the right gauge steel or the right sealant cure rate for our dry climate. Most repairs are completed in a single visit. The brands we use are the same ones specified by serious HVAC contractors in Spokane County, not the budget-grade products that fail in our temperature extremes.
Common Duct Repair & Sealing Problems We See in Opportunity Homes
- DIY duct tape fails within one season in the dry heat. We find brittle, hanging patches during annual inspections. The adhesive dehydrates, the backing cracks, and you’re left with the same leak plus a mess to clean off before proper sealing can begin.
- Smoke film on metal ducts prevents aerosol sealants from bonding. Only mechanical fasteners and mastic hold. We’ve been called back to homes where other contractors sprayed sealant that beaded up and flaked away within months.
- Flex-duct transitions in remodels collapse if not supported, creating accumulations that trap moisture and ash. The 99206 ZIP has dozens of these mixed-era systems, and the failure point is almost always where old metal meets new flex.
- Thermal expansion cracks at trunk seams worsen during our hard freezes. A seam that weeps air in October can gape by January. We check for early-stage separation with our camera systems before it becomes a major repair.

FAQs - Duct Repair & Sealing in Opportunity
Yes. The fine ash from that season bonded to duct interiors in a way that ordinary cleaning cannot fully address, and compromised sealant adhesion at joints you cannot see from the outside. We recommend a camera inspection to check for micro-leaks and film buildup before committing to sealing. Call (844) 685-6342 to schedule - estimates are free.
Water-based mastic applied with a brush or spray rig, cured with mechanical fasteners at stress points. Aerosol sealants and tape products fail on smoke-filmed metal in our dry climate. We’ve verified this in the field across dozens of 99206 homes.
Smoke particulates create a bonded film that must be mechanically removed before sealant will adhere. This adds prep time and often requires multiple cleaning passes. We account for this in our Opportunity pricing, and we show you the camera evidence so you understand why.
Yes. Flex-duct requires support straps every four feet to prevent sagging, and the fabric-to-metal transitions need reinforced mastic, not standard tape. We inspect these hybrid systems carefully because they’re the most common failure point in Opportunity’s mixed-era housing stock.
Yes. We’ve camera-inspected many 1960s systems that showed no pressure-test leakage but had significant smoke-film accumulation at interior corners and joint shoulders. This film degrades metal over time and can harbor odors. A camera inspection reveals what pressure tests cannot. Call (844) 685-6342 for a free look.
