We’re familiar with the full spread of Orange housing: the 1910s-1940s Craftsman homes clustered around Old Towne Plaza, the 1950s-1970s post-war ranches across the 92863 and 92864 ZIPs, and the newer hillside builds pushing toward Santiago Canyon. Each era brings its own duct challenges. The pre-war homes are where our experience shows most - retrofitted duct systems snaked through original redwood framing with thin-gauge metal or early flex duct, often installed with minimal clearance and no access panels. Our Duct Repair & Sealing team handles these jobs with the patience they require.

Why Bellows Air Duct & Vent Co. Is Orange’s Preferred Duct Repair & Sealing Company

We’ve built our reputation in Orange on showing up when we say and standing 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 with no paperwork to argue over. That’s been our policy since 1984.

Orange customers call us because we answer the phone. A live person, 24 hours a day - not a voicemail tree, not an app. When you’re tracking a duct leak that’s blowing conditioned air into your attic on a 95-degree Santa Ana day, you want a human who can dispatch a crew.

Our technicians are background-checked and uniformed, and they arrive with professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies. Every job gets a camera inspection before and after, so you see the condition we found and the condition we left. No claims without proof.

We also know Orange’s specific conditions. The Santa Ana winds that funnel through Santa Ana Canyon and Santiago Canyon just east of the city carry fine-grain desert particulates that coastal Orange County never sees. That grit works into duct seams, hardens mastic seals applied during cooler months, and accelerates contamination in ways that standard repair guides don’t address.

Our Duct Repair & Sealing Services in Orange

Duct Sealing

Most Orange homes lose 20-30% of conditioned air through leaks before it reaches the vents. In Old Towne’s historic district, the problem is worse - retrofitted ducts run through plaster cavities without proper access, so leaks go undetected for years. We seal with mastic compound, not tape, because mastic flexes with temperature swings and fills irregular gaps that tape can’t touch. A typical duct sealing job in Orange runs $280-$480 for a single system, with larger homes or multi-zone setups toward the higher end.

Metal Duct Repair

The thin-gauge galvanized metal ducts installed in Orange’s pre-war homes weren’t built for decades of vibration and thermal cycling. We see rust-through at seams, separated joints where original fasteners have corroded, and sections crushed by later renovation work. Our crew repairs or replaces damaged sections using metal that matches the original gauge, then seals with mastic rated for the temperature range these attic runs see. Metal duct repair in Orange typically ranges from $180-$420 per section, depending on accessibility.

Flex Duct Repair

Flex duct was the quick solution for many Orange retrofits in the 1970s and 1980s. The problem: it’s easily torn at joist penetrations, and the insulation sleeve traps moisture once the inner liner fails. On East Almond Avenue in Old Towne, we found a 1930s Craftsman where a flex duct snaked through a plaster cavity had torn at a floor joist, pulling in attic insulation and dust for years. We closed off the damaged run, installed a new access panel behind a lath-and-plaster wall, and used mastic to re-seal the boot-to-plenum connection, restoring airflow without disturbing the original redwood framing. Flex duct repair or replacement in Orange runs $220-$380 per run.

Duct Insulation

Uninsulated or degraded duct insulation is common in Orange’s older homes, especially where original installers skipped wrapping or where rodents have compromised the vapor barrier. We install foil-faced fiberglass insulation or closed-cell foam wrap depending on the application, with particular attention to attic runs that see extreme temperature swings between Santa Ana heat events and winter nights. Duct insulation in Orange typically costs $320-$650 for a complete system.

Air Leak Repair

Air leaks in Orange homes fall into two categories: visible gaps at registers and plenums, and hidden leaks in wall cavities or crawl spaces. We pressurize the system and use smoke testing to locate leaks that aren’t obvious, then repair with appropriate materials. In Old Towne homes, this often means cutting careful access openings in plaster, repairing the leak, and finishing with removable panels for future service. Air leak repair in Orange ranges from $150-$350 for accessible repairs, with concealed leaks in historic construction toward $400-$650.

Mastic Sealant Application

We apply mastic sealant as a standalone service for Orange homeowners who’ve had tape repairs fail repeatedly. Mastic is a fiber-reinforced compound that remains flexible across temperature extremes - critical in Orange, where attic temperatures can swing from 45°F winter mornings to 140°F summer afternoons. Mastic application for a typical Orange system runs $260-$450.

Trusted Brands We Service in Orange

We stock parts and specify equipment from Rotobrush, Nikro, and Abatement Technologies - the same brands serious HVAC contractors use. For Orange customers, this means faster turnaround because we’re not ordering specialty items. When we encounter a Honeywell or Aprilaire component in your system, we service it with factory-authorized methods. We don’t substitute generic parts where specification matters, especially in the older systems common around Orange’s historic district.

Common Duct Repair & Sealing Problems We See in Orange Homes

• Hidden leaks in plaster-wall cavities. In Old Towne’s plaster-and-lath walls, duct sealing that doesn’t include access panels leaves hidden leaks that continue pulling in dust and moisture from previous renovations. We cut proper access and seal completely.
• Mastic seal failure after Santa Ana wind events. Santa Ana winds push fine-grained desert particulates into ductwork, hardening mastic seals that were applied in cooler months, causing them to crack and leak during the first heat wave. We use high-temperature mastic rated for these conditions.
• Tape adhesion failure on vintage metal ducts. Using modern metal duct tape instead of mastic on vintage thin-gauge metal ducts in pre-war homes leads to rapid adhesion failure as the tape expands and contracts with the area’s wide temperature swings. We remove failed tape and apply mastic properly.
• Contamination from wildfire smoke and desert dust. Orange’s inland position puts it directly in the path of Santa Ana wind events funneling desert particulates through Santa Ana Canyon and Santiago Canyon, driving faster and heavier duct contamination than neighboring coastal cities see. This grit accelerates seal wear and requires more frequent inspection.
