Since 1984, Bellows Air Duct & Vent Co. has repaired and sealed ductwork in the homes that climb Pacific Palisades’s canyon ridges and line its coastal bluffs. We know the mid-century ranches off Sunset Boulevard, the estate properties above Temescal Canyon Road, and the older bungalows tucked into Rustic Canyon’s oak-shaded draws. That local knowledge matters because Pacific Palisades duct systems are not like those in newer developments - they were retrofitted for central air decades after construction, often with irregular runs and connections that fail in specific, predictable ways. After the January 2025 Palisades Fire, that local expertise became even more critical.

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

We’ve served Pacific Palisades homeowners for over 42 years, and our reputation here was built one job at a time - starting with the original custom homes in the Huntington Palisades and working outward through the Alphabet Streets and the Via Bluffs. Ray Castillo, our owner, still reviews every post-fire restoration estimate personally to make sure we’re not missing soot infiltration points that standard inspections overlook.

Our technicians are background-checked, uniformed, and trained on Pacific Palisades’s specific housing stock - the galvanized metal trunks of 1950s ranches, the flex-duct retrofits of 1970s additions, the ad-hoc configurations of pre-war Rustic Canyon cottages. They carry the right materials on their trucks: mastic compound rated for coastal humidity, fiberglass mesh tape for thermal expansion, and replacement flex duct in common diameters so most jobs finish in a single visit.

Calls are answered by a live person, 24 hours a day. Not a voicemail tree. Not an app. A real person who can dispatch a crew to Pacific Palisades tonight if your ducts are pulling contaminated air from a fire-damaged crawlspace.

Our 90-Day Done Right Promise applies to every Pacific Palisades job. If the seal fails, if the odor returns, if the airflow doesn’t balance - we come back at no charge. No paperwork to file. No argument. That’s been our policy since 1984.

Our Duct Repair & Sealing Services in Pacific Palisades

Duct Sealing

Unsealed ductwork in Pacific Palisades homes loses 20-30% of conditioned air to attics and crawlspaces - and after the Palisades Fire, unsealed returns are pulling in ash-laden air from contaminated voids. We seal supply and return plenums with mastic sealant and fiberglass mesh, pressure-testing to verify leakage drops below industry standards. In the Alphabet Streets, we’ve found that original 1960s mastic has turned brittle and powdery, failing under Santa Ana wind pressure that flexes duct trunks. We remove the old material entirely and reseal with modern compounds formulated for coastal temperature swings.

Flex Duct Repair

Flex duct is the weak link in most Pacific Palisades retrofits - crushed where it crosses rafters, sagging between supports, or pulled loose at collar connections. Post-fire, we’ve seen something worse: smoke-ash deposits that have glued flex duct seams and liner surfaces into a solid, brittle mass. Standard brush cleaning can’t remove it. On Via de la Paz, we serviced a 1950s ranch-style home where the original metal duct trunk had pulled away from a joist, creating a 3-inch gap that sucked ash-laden air from the crawlspace into the living zones. Our crew sealed the breach with mastic and fiberglass mesh tape, then installed a new flex branch to restore balanced airflow, abating the smoke odor that had plagued the owner since the fire. Flex duct replacement in Pacific Palisades runs $180-$340 per branch, including labor and materials.

Metal Duct Repair

Original 1940s-1960s galvanized metal ducts in Pacific Palisades homes develop rust at seams, separations at drive cleats, and cracks where seismic movement or Santa Ana wind loading has stressed the trunk lines. We repair with sheet metal patches, drive cleat replacement, and structural reinforcement - preserving original ductwork where it’s sound, replacing sections where corrosion has compromised integrity. Metal duct repair in Pacific Palisades typically ranges from $220 for a localized patch to $580 for trunk section replacement with transitions.

Duct Insulation

Uninsulated or degraded duct insulation in Pacific Palisades attics wastes energy and creates condensation that breeds microbial growth. We install foil-faced fiberglass insulation or closed-cell foam wrap, depending on clearance and access. In Temescal Canyon homes with tight attic spaces, we often use pre-formed insulation sleeves that install without tearing out finished ceilings. Duct insulation in Pacific Palisades runs $3.50-$5.20 per linear foot, with most single-system homes needing 80-150 feet.

Mastic Sealant Application

Mastic is our preferred sealant for Pacific Palisades’s coastal climate - it remains flexible where tapes dry and crack, and it bonds to metal, flex duct, and fiberglass board. We apply with brushes at seams and connections, then embed fiberglass mesh tape at high-stress joints for reinforcement. The daily marine layer here adds residual coastal humidity that extends cure time; we schedule pressure testing for 48 hours after application to ensure full set. Mastic sealing of a complete system in Pacific Palisades typically costs $340-$520.

Air Leak Repair

Air leaks in Pacific Palisades ductwork often trace to specific local failure modes: unsealed return plenums pulling particulate from fire-contaminated attics, brittle mastic cracking under wind pressure, or flex duct pulled loose at collars by seismic movement. We locate leaks with blower-door-assisted pressure testing and infrared scanning, then repair with methods matched to the leak type - not just slapping tape over symptoms. Air leak repair in Pacific Palisades ranges from $150 for a single accessible breach to $480 for multi-point sealing with pressure verification.

Trusted Brands We Service in Pacific Palisades

We stock parts and materials from Nikro, Honeywell, and Aprilaire on every Pacific Palisades service truck - the same brands serious HVAC contractors specify for commercial installations. That means no waiting for a parts run to the Valley when your flex duct collar fails or your motorized damper seizes. For post-fire restoration work, we deploy Nikro HEPA-rated negative air machines and Honeywell media filters rated for fine particulate, because standard residential equipment can’t handle the soot-film signature we’re seeing in Pacific Palisades ducts right now. Most repairs finish in one visit because we arrive prepared for what your specific home is likely to need.

Common Duct Repair & Sealing Problems We See in Pacific Palisades Homes

• Smoke-ash deposits gluing flex duct seams shut. In Pacific Palisades homes that ran HVAC during the January 2025 Palisades Fire, we’ve found flex duct liner bonded into a solid, brittle mass by condensed ash and soot. Standard brush cleaning can’t remove it. The duct section must be cut out and replaced.
• Unsealed return plenums pulling contaminated attic air. Many Pacific Palisades ranches have return plenums sealed with failing tape or no sealant at all. After the fire, these gaps became intake points for ash-laden attic air, recontaminating ducts we’d already cleaned. We now seal plenums with mastic and mesh as standard protocol on every post-fire job.
• Brittle mastic on mid-century metal ducts cracking under Santa Ana wind pressure. The canyon topography of Temescal and Rustic canyons accelerates wind across rooflines, flexing duct trunks and cracking aged mastic. We remove all old sealant and reapply modern flexible compounds rated for thermal and mechanical stress.
• Dead-leg duct sections from retrofitted central air. Pacific Palisades homes often have duct runs added in the 1970s-1980s that terminate in unused wall cavities or bypassed by later renovations. These dead legs collect moisture, debris, and post-fire particulate. We cap or remove them to restore system efficiency and prevent recontamination.
