Fast, Reliable Duct Repair & Sealing Across Arcadia
Most Arcadia homeowners with duct problems call us because their utility bill jumped, a room won’t heat evenly, or they smelled smoke long after the fires were out. We’re Bellows Air Duct & Vent Co., and we’ve been driving out to Arcadia from our Miami base since 2012. Our Duct Repair & Sealing team can usually reach the 91006, 91007, 91066, and 91077 ZIP codes within the hour during business hours, and we keep live dispatchers on the phone around the clock. Call (844) 685-6342 for a free estimate.
Why Bellows Air Duct & Vent Co. Is Arcadia’s Preferred Duct Repair & Sealing Company
Arcadia’s split personality of aging ranch homes and massive new construction means duct problems here look different than in neighboring cities. We’ve learned that over 14 years. Our technicians know which Highland Oaks attics have original 1960s flex duct that crumbles at the touch, and which Santa Anita Golf Course-area builds need post-construction sealing before the owners even unpack.
Our reviews from Arcadia customers consistently mention two things: we show up when we say we will, and the price on the phone matches the price on the invoice. No bait coupons. No upsells at the door. Our 90-Day Done Right Promise is stamped on every job - if it’s not right, we make it right, no paperwork, no arguing.
Calls are answered by a live person, 24 hours a day. Not voicemail. Not an app. A real person who can dispatch a background-checked, uniformed technician to your Arcadia home.
Our Duct Repair & Sealing Services in Arcadia
Duct Sealing & Air Leak Repair
Air leaks in Arcadia ductwork waste 20-30% of conditioned air on average. In foothill homes near the Angeles National Forest boundary, we’ve measured worse. Santa Ana winds pressurize systems already compromised by ash infiltration, forcing leaks at joints and seams that were tight a decade ago. Our crew pressure-tests the system, maps every leak with a camera, and seals with mastic or mechanical fasteners depending on the duct material. We verify the fix with a second pressure test. Camera inspection before and after, every time.
Metal Duct Repair
Arcadia’s older ranch homes on Foothill Boulevard and throughout Upper Rancho often have original galvanized sheet-metal ductwork that has never been opened since installation. Metal seams split. Sections crush under shifted insulation. Rust forms where roof leaks dripped decades ago. We cut out damaged sections, fabricate replacements on-site, and seal with mastic rated for high-temperature cycling. For homes in the 91006 ZIP code particularly, metal duct repair is often the right choice over full replacement - the original steel is thicker gauge than what’s sold today.
Flex Duct Repair & Replacement
Flex duct in Arcadia’s 1950s-1970s housing stock has reached end of life. The plastic liner becomes brittle. The fiberglass insulation compacts. After the 2020 Bobcat Fire, we replaced flex duct in dozens of homes where post-fire cleaning attempts tore the original material apart. We install new flex with proper support straps and sealed collars, rated for the temperature swings these attics see. If your flex duct is original, replacement is usually smarter than repair.
Duct Insulation & Mastic Sealant
Arcadia’s foothill position means wider temperature swings than lower San Gabriel Valley cities. Uninsulated or poorly insulated ductwork in attics loses efficiency fast. We wrap with formaldehyde-free insulation and seal every penetration with mastic - not tape, which degrades. For homes in the wildfire exposure zone, we also evaluate whether your duct insulation itself has absorbed smoke residue and needs replacement.

Trusted Brands We Service in Arcadia
We carry Rotobrush duct cleaning equipment and stock Aprilaire and Honeywell air filtration components for Arcadia jobs. When a Highland Oaks homeowner needs a Honeywell electronic air cleaner installed after fire season - like the Upper Rancho job on Foothill Boulevard where we found split seams from ash-laden Santa Ana winds - we don’t order parts and make you wait. Our trucks carry the common sizes. Abatement Technologies HEPA filtration accessories are on hand for post-fire remediation work. The right part, the same day, most of the time.
Common Duct Repair & Sealing Problems We See in Arcadia Homes
- Wildfire ash destroys mastic seals. In Highland Oaks and Upper Rancho, we routinely find a visible layer of fine gray ash and smoke residue coating supply and return plenums after mountain wildfires. The intensity of this contamination is unmatched in lower-elevation SGV cities just a few miles south. Ash is abrasive and alkaline; it eats mastic and forces joints apart under Santa Ana wind pressure.
- Original flex duct crumbles during any disturbance. Arcadia’s 1960s ranch homes have flex duct that has baked in attics for sixty years. It tears when we touch it. It tears when insulation shifts. We replace rather than patch - the material is past reliable service life.
- New luxury homes leak from construction debris gaps. The 4,000-6,000 square foot builds near the Santa Anita Golf Course often have duct systems installed before final cleanup. Drywall dust, insulation fibers, and unsealed crawlspace penetrations leak conditioned air and draw in ash from below. Post-construction sealing is essential, not optional.
- Metal duct seams split from overpressurization. During Santa Ana events, wind-driven pressure differentials force systems beyond their design limits. Original sheet-metal seams in 91006 and 91007 ZIP codes pop open. We find this less often in lower-elevation Arcadia neighborhoods, but still worth inspecting after any major wind event.

Pricing for Duct Repair & Sealing in Arcadia, CA
A typical mastic sealant job for a 1,500-2,500 square foot Arcadia ranch home runs $280-$450. Metal duct repair, including fabrication and installation of replacement sections, typically costs $180-$340 per section with mastic sealing. Full flex duct replacement in an older Arcadia home averages $12-$18 per linear foot, with most jobs falling between $800 and $1,800 depending on attic accessibility. Duct insulation wrapping runs $4-$7 per linear foot.
New luxury homes in Arcadia with complex multi-zone systems require more labor - the sheer duct footage is significantly greater than a typical SGV residence. These jobs often start around $1,200 for comprehensive sealing and can reach $3,500+ for full-system remediation with construction-debris cleanup.

FAQs - Duct Repair & Sealing in Arcadia
They do both, and the damage is real. Santa Ana winds channel off the San Gabriel Mountains and create pressure differentials that force ash and fine particulates into duct seams, then split those seams when gusts exceed 40 mph. In a 1960s ranch home on Foothill Boulevard in Upper Rancho, we found metal duct seams split from ash-laden Santa Ana winds overpressurizing the system. Our crew sealed the joints with mastic and installed a Honeywell electronic air cleaner to trap residual particulates. Call (844) 685-6342 for a free inspection if you’ve noticed uneven airflow after a wind event.
Yes, and possibly more urgently than an older home. Arcadia has one of the highest teardown-and-rebuild rates in the SGV, and new 4,000-6,000 square foot homes often have duct systems installed before final construction cleanup. Drywall dust, insulation fibers, and unsealed crawlspace gaps leak conditioned air and allow ash infiltration. We recommend post-construction duct sealing and camera verification before move-in. Call (844) 685-6342 to schedule - estimates are free.
Water-based mastic, applied thick, is the right choice for Arcadia’s wildfire-exposure zone. Tape degrades in heat and ash is alkaline enough to attack adhesive backings. Mastic remains flexible, fills irregular gaps, and withstands the temperature cycling these attics see. We use professional-grade mastic rated for 250°F+ and verify coverage with camera inspection. For an exact specification for your home, call (844) 685-6342.
Signs of failure include renewed smoke odor when the system runs, dust accumulation at supply vents, uneven heating or cooling, and utility bills that creep back up. We recommend annual camera inspection for homes in the foothill exposure zone, especially in 91006 and 91007 ZIP codes. Our 90-Day Done Right Promise covers any seal failure at no charge, but proactive inspection catches problems before they spread. Call (844) 685-6342 to book a camera inspection.
Yes, in most cases. We cut out the crushed section, fabricate a replacement from matching gauge steel, and seal with mastic. Full replacement is only necessary if the damage extends multiple sections or if rust has compromised adjacent areas. For Arcadia’s original 1950s-1970s metal ductwork, repair is usually the better value - the original material is heavier gauge than modern equivalents. Call (844) 685-6342 for a free assessment and exact quote.
