Why Bellows Air Duct & Vent Co. Is Riverside’s Preferred Duct Repair & Sealing Company
We’ve worked Riverside long enough to know the difference between a Casa Blanca ranch built in 1962 and an Orangecrest tract home from 1998. That matters because the ductwork fails differently, and fixing it right means recognizing which problem you’re looking at before you open the toolbox.
Our technicians are background-checked, uniformed, and equipped to handle most repairs in one trip. We camera-inspect every system before and after work begins, so you see what we see, not just take our word for it. Our 90-Day Done Right Promise is stamped on every job in writing: if it’s not right, we return at no charge, no paperwork, no arguing.
Calls are answered by a live person, 24 hours a day. Not a voicemail tree, not an app. When your AC is pushing 90°F attic air through a torn flex duct in July, you want a human being who can get a crew moving.
We don’t bait-and-switch. The price we quote on the phone is the price on the invoice, disclosed before a single tool is lifted. That’s been our practice since 1984.
Our Duct Repair & Sealing Services in Riverside
Flex Duct Repair
Riverside’s older tracts near UCR and downtown in the 92501 and 92507 ZIP codes are where we see the most flex duct damage in the entire Inland Valley. Roof rats nest inside attic-routed flex runs, shredding the inner liner and collapsing the sleeve until the duct is essentially a loose bag pulling unfiltered attic air straight into your bedrooms. Our crew recently re-sealed a 1960s ranch off Arlington Avenue near the Casa Blanca border, where mastic on the original metal supply trunk had cracked and roof rats had chewed through a flex branch feeding the back bedrooms. We patched the flex, re-wrapped it with foil tape and mastic, and sealed every joint on the trunk with a fresh mastic layer, done in one trip so the homeowner didn’t lose another day of cooling. A typical flex duct section repair in Riverside runs $180-$320.
Mastic Sealant Application
The tar-based mastic used on 1950s through 1970s metal ducts in Arlington, Arlanza, and Casa Blanca neighborhoods oxidizes and cracks after decades of Riverside’s extreme attic heat, which routinely exceeds 140°F in summer. DIY repairs with new mastic often fail because the old sealant residue prevents proper bonding to oxidized metal. We strip back failed material, prep the metal surface, and apply fresh mastic rated for sustained high temperatures, then verify the seal with pressure testing. Mastic resealing of a supply trunk in Riverside typically runs $280-$450.
Duct Sealing
Seasonal Santa Ana wind events create pressure differentials across Riverside building envelopes that force exterior PM2.5, desert dust, and wildfire ash through every gap in the duct system. In homes with original ductwork, supply boots often separate from drywall, return plenums leak at the filter rack, and crossover ducts in crawl spaces disconnect entirely. We seal with a combination of foil tape, mastic, and mechanical fasteners depending on the location and accessibility. Whole-system duct sealing for a typical Riverside single-story runs $380-$650.
Metal Duct Repair
Original fiberglass-lined sheet metal in Riverside’s postwar tracts corrodes at seams and separates at drive cleats after sixty-plus years of thermal cycling. We patch localized corrosion, replace damaged sections with matching gauge galvanized steel, and reconnect with proper S-locks and drives rather than the duct tape patches that fail within a season. Metal duct section replacement in Riverside typically runs $240-$480 depending on accessibility and length.

Trusted Brands We Service in Riverside
We carry professional-grade equipment and materials from Nikro, Honeywell, and Aprilaire, the same brands serious HVAC contractors specify for the Inland Valley market. Our trucks stock flex duct in common diameters, foil-backed insulation, high-temperature mastic, and mechanical fasteners so we’re not making a supply run while your house sits open. That inventory discipline is how we finish most Riverside jobs in a single visit.
Common Duct Repair & Sealing Problems We See in Riverside Homes
- Roof rat damage inside attic flex ducts goes unnoticed until the AC runs. Chewed liners pull unfiltered attic air, but homeowners only call after dust blooms from vents. We inspect with cameras before cutting anything.
- DIY mastic repairs on 1950s-70s metal ducts fail because the old tar-based sealant never bonded to oxidized metal, leaving gaps that Santa Ana winds force open. Proper prep is the fix, not more mastic on top of failure.
- Skipping the pre-repair inspection in pre-1978 homes risks asbestos duct wrap crumbling during work, contaminating the home and halting the job. We check for asbestos-containing materials before disturbing anything.
- Extreme attic temperatures in Orangecrest and newer tracts degrade flex duct foil and inner liners faster than manufacturer ratings predict, creating tears that pull 140°F attic air into the supply stream every time the compressor kicks on.

FAQs - Duct Repair & Sealing in Riverside
We can usually repair a damaged section without replacing the entire run. Our technician cameras the full line to confirm the damage is localized, then patches with new flex duct, proper collars, and mastic, pressure-testing afterward to verify no additional leaks. Most section repairs in Riverside run $180-$320. Call (844) 685-6342 for an exact quote, estimates are free.
We inspect for asbestos-containing materials before disturbing any ductwork. If we find asbestos wrap, we coordinate with certified abatement specialists and do not proceed until proper containment and removal protocols are in place. Never let a contractor cut or scrape pre-1978 duct insulation without this check. Call (844) 685-6342 and we’ll schedule a camera inspection to assess what you’re working with.
Standard cloth duct tape adhesive degradates above 120°F, and Riverside attics exceed that for months. The tape dries, cracks, and peels, reopening the gap. We use foil tape rated for sustained high temperatures and mechanical reinforcement, then seal with mastic for a permanent fix. A proper repair costs more than a tape patch upfront. It costs far less than doing the job three times. Call (844) 685-6342 for an estimate.
We clean and prep the metal surface, remove failed old mastic, apply fresh high-temperature sealant to every joint and seam, and reinforce with foil tape at stress points. If the trunk has localized corrosion, we patch with matching gauge steel rather than replacing a sound system. Most trunk resealing jobs in Riverside run $280-$450 and are done in one visit. Call (844) 685-6342 to schedule.
We repair ductwork in detached structures as well as main residences, provided the system is accessible and we can verify safe working conditions. Workshop ductwork in Riverside often uses the same flex or metal materials as the main house, and we bring the same equipment and pricing. Call (844) 685-6342 to describe the setup and we’ll give you a straight answer on what’s involved.
