We’ve been driving out to Cheney from our Spokane-area routes for over 42 years. We know the difference between a 1970s rental on Elm Street with a dirt-floored crawlspace and a newer build out toward Fish Lake Trail with a tight but finished basement. That local knowledge changes what we bring, how we access the ductwork, and what repair method lasts. Cheney’s forced-air systems work harder than most - six months of continuous heating through cold, dry winters - and when ducts leak, you’re paying to heat your crawlspace or attic.
Why Bellows Air Duct & Vent Co. Is Cheney’s Preferred Duct Repair & Sealing Company
Ray Castillo built this company on the idea that a homeowner should never have to argue about whether a job was done right. Our 90-Day Done Right Promise is stamped on every Cheney repair: if airflow doesn’t improve or the seal fails, we return at no charge, no paperwork, no runaround. That promise has kept us in business since 1984.
Our technicians are background-checked, uniformed, and trained on the specific duct failures we see in Cheney’s housing stock - loose flex duct joints in EWU-area rentals, rusted metal seams in mid-century homes, and insulation degraded by attic temperature swings. Every repair is camera-inspected before and after, so you see the leak and you see the fix.
We answer calls with a live person 24 hours a day. Not an app. Not a callback queue. When a landlord near campus has a heating emergency between tenants, or a homeowner on the outskirts notices their furnace running nonstop, we pick up and schedule.
Our Duct Repair & Sealing team carries mastic sealant, flex duct, metal repair sleeves, and insulation rated for the temperature swings of the Columbia Plateau. We don’t make two trips because we didn’t bring the right material.
Our Duct Repair & Sealing Services in Cheney
Duct Sealing
Most Cheney homes lose 20-30% of heated air through leaks before it reaches the rooms. In the EWU rental belt, we regularly find disconnected joints where decades of tenant turnover and skipped maintenance have left gaps wide enough to slide a hand through. We seal with mastic - a fibrous paste that hardens into a permanent, flexible bond - not tape that peels in dry attic heat. A typical duct sealing job in Cheney runs $280-$480 for a partial system and $550-$850 for full trunk-and-branch sealing. We disclose the exact scope and price before we lift a tool.
Flex Duct Repair
Flex duct is common in Cheney’s 1960s-1990s rentals, and it’s often the first thing to fail. The plastic liner tears, the wire helix kinks, or - most commonly - the joint slips off the collar in a crawlspace. On a 1970s rental near Elm Street, we found a long tear in the flex duct under the crawlspace, likely from a previous pest treatment. We used mastic sealant to repair the main trunk and replaced a section of Rotobrush-cleaned flex duct, restoring airflow to the upstairs bedrooms. Flex duct repair in Cheney typically costs $180-$340 for a section replacement, $220-$400 if we need to reroute around an obstruction.
Metal Duct Repair
Older homes near EWU and in downtown Cheney often have galvanized metal trunk lines that have carried heated air since the Johnson administration. After forty or fifty winters, condensation rusts through the seams. We cut out the damaged section, fabricate a replacement sleeve, and seal with mastic and mechanical fasteners. Metal duct repair in Cheney runs $320-$580 depending on accessibility and the extent of corrosion. If the trunk is too far gone, we’ll tell you straight - no patch job that fails in two seasons.
Duct Insulation
Cheney’s temperature swings are hard on attic insulation. A duct that loses heat through thin or degraded insulation forces your furnace to run longer, burning more fuel and wearing the blower. In small apartment buildings near campus, we often find insulation that’s compressed, water-stained, or missing entirely. We install foil-faced fiberglass insulation rated for the temperature extremes of the Columbia Plateau, sealed at every seam. Duct insulation work in Cheney costs $380-$650 for a typical residential system.
Mastic Sealant Application
Mastic is our standard for every metal seam and flex duct joint we touch. Unlike foil tape that dries and cracks in Cheney’s low humidity, mastic remains flexible, expanding and contracting with the duct through summer and winter. We brush it on thick - a proper mastic seal is messy to apply and permanent when cured. This is the method we used on that Elm Street rental, and it’s what we specify for every Cheney job where long-term performance matters more than a quick appearance of repair.
Air Leak Repair
Some leaks aren’t in the duct itself but in the plenum, return box, or filter rack - the connections between components that get overlooked. We pressurize the system and use smoke pencils to find every escape path, then seal each one. In Cheney’s windy climate, even a small return leak can pull unfiltered Palouse dust directly into your furnace and blower. We fix the leak and show you the before-and-after on camera.

Trusted Brands We Service in Cheney
We repair and seal ductwork connected to equipment from every major manufacturer, and we stock repair materials from Rotobrush, Nikro, and Abatement Technologies on our service vehicles. That means no waiting on parts for a standard Cheney repair. For air quality upgrades after sealing, we also work with Honeywell and Aprilaire filtration and humidification products - useful in Cheney’s dry winters when static electricity and dry sinuses are as common as leaky ducts. If your system uses a specific brand of flex duct or metal fitting, we’ll match it or tell you why a different specification works better for your application.
Common Duct Repair & Sealing Problems We See in Cheney Homes
- Flex duct disconnects in unsealed crawlspaces. Common in Cheney’s 1960s-70s off-campus rentals, where decades of tenant turnover mean nobody checked the joints. The duct slips off the collar, and heated air pours into the dirt below while bedrooms upstairs go cold. We reconnect with mechanical fasteners and mastic, then verify airflow at every register.
- Metal duct seams rusted through from winter condensation. In older homes near EWU, galvanized steel has carried moist heated air since before most current students were born. The seams corrode, creating pinholes and gaping leaks that bypass the filter entirely. We replace damaged sections and seal with mastic for a repair that outlasts the original installation.
- Duct insulation degraded in apartment building attics. Cheney’s small apartment buildings near campus often have insulation that’s been compressed by maintenance traffic, stained by roof leaks, or simply aged out. Without proper insulation, ducts sweat in summer and lose heat in winter, forcing the furnace to overwork. We remove and replace with properly rated material.
- Palouse dust infiltration through return leaks. Cheney’s west-southwest winds carry fine loess agricultural dust that finds every gap in a return duct system. We see multi-year compacted layers in rental units where property managers never scheduled duct cleaning during tenant turnover. Sealing the returns stops the infiltration at the source.

FAQs - Duct Repair & Sealing in Cheney
Every 3-5 years for active rentals, or whenever tenant turnover reveals airflow problems. In Cheney’s EWU rental belt, we find that property managers routinely replace carpet and paint between tenants but skip the ductwork, allowing leaks and contamination to compound across multiple lease cycles. A camera inspection between tenants catches disconnects before they waste another heating season. Call (844) 685-6342 to schedule - estimates are free, and we work around move-in dates.
Yes. Our technicians carry low-profile tools and flexible repair materials specifically for Cheney’s older rentals with 18-inch crawlspaces and dirt floors. We’ve worked under houses on Elm Street and near campus where the only access is a sidewalk hatch. If we can’t fit, we’ll tell you upfront - but we rarely can’t fit. Call (844) 685-6342 and describe your access; we’ll bring the right equipment.
Mastic is ideal for Cheney’s conditions. Unlike tape adhesives that degrade in low humidity and temperature extremes, mastic cures to a flexible, permanent bond that expands and contracts with the duct through our 80-degree summer-to-winter swings. We’ve inspected repairs after five Cheney winters and found mastic still fully adhered. It’s the only sealing method we warranty.
Yes. Downtown Cheney’s duplexes and small apartment buildings often share attic duct runs with multiple flex duct drops to individual units. We repair or replace individual branches without disrupting neighboring units, and we coordinate with landlords or property managers for access. Typical duplex flex duct repair in downtown Cheney runs $200-$380 per branch. Call (844) 685-6342 for an exact quote - we’ll inspect the shared attic space and specify what each unit needs.
Even newer homes on Cheney’s outskirts develop leaks from settling, vibration, and the thermal expansion and contraction of our extreme seasonal temperature swings. Builders often use tape at joints rather than mastic, and that tape fails within the first decade. We also find leaks where ducts pass through unconditioned attic spaces that freeze hard in January and bake in July. The fix is the same: camera inspection, mastic sealing, and verification of airflow at every register.
