Fast, Reliable Duct Repair & Sealing Across Pacific Palisades
Duct repair and sealing in Pacific Palisades typically costs between $280 and $950, with most homes completed in a single visit. If your HVAC system is blowing dust, struggling to maintain temperature, or running constantly, the problem is often leaks or collapsed sections in the ductwork behind your walls.
We’ve been driving out to Pacific Palisades since 1984, and we know the difference between a quick seal job and the kind of repair that actually lasts in these homes. Many of the houses here, from the ranch-style builds off Sunset Boulevard to the hillside estates above Chautauqua, were constructed with flex duct and duct board that has now been in place for fifty years or more. The marine layer rolls in off the Pacific, the Santa Ana winds tear through the canyons, and that original ductwork takes a beating that newer construction simply doesn’t face. When you call us at (855) 401-6006, a live person answers, day or night. We’ll give you an honest price before we start, and we’ll stand behind the work for 90 days in writing.
Why Bellows Air Duct & Vent Co. of California Is Pacific Palisades’s Preferred Duct Repair & Sealing Company
Pacific Palisades homeowners have called us back for decades because we treat their houses like the long-term investments they are. We’re not chasing a quick coupon deal and a faster exit. Our Duct Repair & Sealing team has worked on homes from the Alphabet Streets to the Highlands, and we understand how the local climate and the 2025 Palisades Fire have changed what these systems need.
Our reputation here is built on showing up when we say we will, wearing a uniform, and explaining what we found with a camera inspection you can see for yourself. We don’t tell you something is broken unless we can show you the picture. Calls are answered by a live person 24 hours a day, not a voicemail tree, and our technicians are background-checked and employed by us, not subcontracted out. Roger Castañeda, who leads this company, has insisted on that standard since 1984.
Most Pacific Palisades jobs are completed in one visit because we arrive with the right materials for mid-century flex duct, metal trunk lines, and the mastic sealant these older systems require. We don’t have to order parts and come back next week. That matters when your system is pumping wildfire ash or fiberglass fibers into the air your family breathes.
Our Duct Repair & Sealing Services in Pacific Palisades
Duct Sealing
Leaky ducts are the single biggest efficiency killer in Pacific Palisades homes, and they’re especially common in the mid-century builds that dominate this area. We seal joints, connections, and penetrations with professional-grade mastic sealant, not the cheap foil tape that dries out and fails within a couple of seasons. In homes that survived the January 2025 Palisades Fire, proper sealing also prevents re-circulation of any residual ash or particulate that settled in wall cavities. A typical duct sealing job in Pacific Palisades runs $280-$550 for a single system.

Flex Duct Repair
The flex duct installed in Pacific Palisades homes from the 1940s through the 1970s was never designed to last this long. We’ve found collapsed trunk lines in attics above Palisades homes where the original wire helix has rusted through, and torn sections near registers where decades of vibration have worn holes in the liner. The Santa Ana winds that funnel through Topanga and Las Flores Canyons create pressure differentials that stress these systems further. We replace compromised sections with new, insulated flex duct rated for California Title 24 standards, and we secure it properly so it doesn’t sag or kink. Flex duct repair in Pacific Palisades typically ranges from $320-$680 depending on accessibility and length.

Metal Duct Repair
Some Pacific Palisades homes, particularly the larger estates built in the 1950s and 1960s, used galvanized steel trunk lines with flex duct branches. Those metal ducts corrode at seams, separate at joints, and can develop whistling leaks that waste conditioned air in your crawl space or attic. We repair metal ductwork with proper mechanical fastening and sealant, and when sections are too far gone, we fabricate replacements that match the original dimensions. Metal duct repair in Pacific Palisades generally runs $450-$950.

Duct Insulation
Uninsulated or degraded duct insulation is a particular problem in Pacific Palisades because of the marine-layer moisture that condenses on cool duct surfaces during morning fog events. That condensation soaks into old insulation, compresses it, and eventually breeds mold inside the duct liner. We install new insulation with proper vapor barriers, especially critical for ducts running through unconditioned attic spaces that see those rapid humidity swings. Duct insulation work in Pacific Palisades typically costs $380-$720.

Mastic Sealant Application
We emphasize mastic sealant on every Pacific Palisades job because it outlasts tape, fills irregular gaps in aging duct board, and creates a continuous seal that pressure tests verify. Our technicians apply it by hand to every accessible joint, then run a duct blaster test where possible to confirm we’ve hit target leakage rates. This is the standard we apply whether we’re sealing five joints or fifty.

Air Leak Repair
Air leaks in Pacific Palisades homes often occur where ducts penetrate fire-rated walls, where original installers cut rough openings, or where settling has pulled connections apart. We repair these with proper collar installations, fire-stop sealant where required, and mechanical support to prevent future separation. Every repair is photographed before and after for your record.

Trusted Brands We Service in Pacific Palisades
We stock parts and materials from Honeywell, Aprilaire, and Nikro on our service vehicles, which means most Pacific Palisades repairs don’t wait on a supply run. Honeywell and Aprilaire provide the filtration and zoning components that integrate with older systems without forcing a full replacement. Nikro manufactures the HEPA containment and negative-air equipment we use when fire contamination or asbestos-containing materials are present. That matters in Pacific Palisades right now. After the Palisades Fire, we’ve encountered ash and debris that standard residential equipment can’t safely handle, and we don’t guess about containment. We bring the right tools, or we don’t take the job.
Common Duct Repair & Sealing Problems We See in Pacific Palisades Homes
- Legacy flex-duct collapse from decades of unsealed joints. The original flex duct in pre-1970s Pacific Palisades homes was often hung with inadequate support, and Santa Ana wind vibration plus natural settling has caused sagging, kinking, and complete collapse in attic runs. We find this weekly in the Alphabet Streets and the Village neighborhoods.
- Mold growth inside duct liner from marine-layer condensation. Pacific Palisades’s unique position where cool Pacific moisture meets warm interior air creates condensation cycles inside ductwork, especially in uninsulated flex duct. That moisture feeds mold hidden behind original wood paneling or in soffit chases, and homeowners often smell it before they see it.
- Asbestos-containing duct tape or mastic on pre-1978 systems. Many Pacific Palisades homes built before 1978 used asbestos-containing materials for duct sealing and insulation wrapping. Disturbing these during repair requires specialized abatement protocols. We identify suspect materials, stop work, and coordinate proper containment rather than exposing your home or our technicians.
- Wildfire ash and particulate contamination from the January 2025 Palisades Fire. Homes that survived the fire but ran HVAC systems during smoke events have ducts lined with fine ash containing burned building materials, including potentially asbestos-containing roofing from older structures. Standard cleaning doesn’t address this. We use HEPA-rated containment and negative-air protocols developed for environmental remediation, not residential maintenance.
Pricing for Duct Repair & Sealing in Pacific Palisades, CA
We’re upfront about numbers because we’ve seen what happens when contractors lowball by phone and triple the price at the door. Here’s what duct repair and sealing actually costs in Pacific Palisades:
| Service | Typical Range in Pacific Palisades |
|---|---|
| Duct sealing (mastic, single system) | $280 - $550 |
| Flex duct repair (section replacement) | $320 - $680 |
| Metal duct repair (seams, sections) | $450 - $950 |
| Duct insulation replacement | $380 - $720 |
| Fire-ash / HEPA containment repair | $650 - $1,400 |
What moves you within these ranges? Accessibility matters: a duct buried behind a 1960s plaster soffit takes longer than one in an open attic. The extent of contamination from fire ash or mold determines whether we can seal in place or must remove and replace. And the age of your system affects whether we can source compatible fittings or need to fabricate transitions. We inspect with a camera, show you what we found, and give you one price before any work begins. Estimates are free. Call (855) 401-6006.
Standing offers: $50 off any repair over $250. Free second opinion on any written estimate. Permanent 5% senior and veteran discount.

FAQs - Duct Repair & Sealing in Pacific Palisades
They can often be repaired if the damage is localized to the last few feet near the register boot. We cut out the torn section and splice in new insulated flex duct with a proper collar and mastic seal. If the tear extends back into the wall cavity, or if the surrounding duct shows multiple failure points, replacement of that branch line is the better investment. Call (855) 401-6006 and we’ll camera-inspect to give you a straight answer.
Most Pacific Palisades calls are scheduled within 24 to 48 hours, and same-day service is often available for systems that are completely down or circulating contaminated air. We keep a live person on the phone 24 hours a day to route urgent calls. Roger Castañeda built that system because he knows duct problems don’t wait for business hours.
Yes. We service the full Pacific Palisades area, from the Alphabet Streets and the Village up to the Highlands, the Huntington Palisades, and the hillside estates along Chautauqua and Temescal Canyon Road. Narrow streets and steep driveways don’t stop us; we bring the right vehicle and equipment for every access condition.
It can be, primarily because Pacific Palisades homes are older on average and more likely to have the mid-century flex duct and duct board that requires specialized repair techniques. Fire contamination from January 2025 has also added HEPA containment steps that don’t apply in neighboring cities. However, our pricing is consistent across our service area; we don’t charge a “Palisades premium.” The difference is in what your specific home needs, not your ZIP code.

Roger Castañeda has honored that promise for over 42 years, and it’s stamped on every invoice we write.
