We’ve been answering calls from Malibu homeowners since 2004, and we know what decades of salt air, remodels, and wildfire smoke do to a duct system. Our Air Duct Repair team will give you a written price before any work starts. No bait pricing, no surprise invoice after the fact.

Why Linden Air Duct Cleaning Is Malibu’s Preferred Air Duct Repair Company

Malibu homes are not like tract housing in the Valley. They’re built into canyon slopes, perched above the Pacific, or sitting on beach sand where salt and moisture work on metal year-round. That’s why our approach starts with a camera inspection instead of a guess. We find what’s actually failing before we touch anything, and we document it so you can see it yourself.

Every technician who walks up your driveway in Malibu is background-checked, identity-verified, and arrives in a clean, marked uniform. Before the visit, you get that technician’s name and photo on your phone. At the door, they show a photo ID badge. That’s the Threshold Standard, and it’s been the operating rule since 2004, not a pandemic-era afterthought. Marcus Veale set that standard and it hasn’t budged.

We carry a 365-Day Done Right Promise in writing on every repair. If a covered repair fails, we come back at no charge. Not a pro-rated trip fee. Not a “we’ll take a look.” We come back and make it right. Malibu homeowners deal with enough uncertainty from fires and mudslides. Your duct repair shouldn’t add to it.

Duct Replacement in Malibu

Duct Replacement in Malibu usually becomes necessary because the existing runs have physically failed, not because they’re dirty. We see original 1950s and 60s metal trunk lines crushed flat where a remodeler stepped framing over them, flexible ducts disconnected at the plenum, and runs that have simply corroded through from salt-laden marine-layer air. When that happens, the back bedrooms get almost no supply air while the blower motor works overtime, and the fix is replacement, not cleaning.

A full duct replacement in Malibu typically runs $1,800 to $2,800 for a standard single-zone home, though hillside estates with multi-zone systems can run higher. You’ll get a written price for the entire system before we cut into anything. That price covers materials, labor, sealing, and cleanup. No per-vent games.

What Replacement Involves

We remove the failed sections, size the new runs to the actual heating and cooling load, and seal every joint with mastic, not tape. Then we test the static pressure to confirm the blower isn’t fighting the ductwork. A properly sealed system moves air the way it was designed to, and you’ll feel the difference in rooms that have been dead for years.

When Replacement Beats Patching

If your ducts have multiple disconnected joints or extensive corrosion, patching one section just shifts the leak elsewhere. Replacing the run with the right gauge and insulation is often cheaper than chasing leaks for a decade. We’ll show you the camera footage and let you decide. Most Malibu homeowners see what we see and go with replacement.

Ductwork Installation in Malibu

Ductwork Installation in Malibu usually comes up in two situations: a post-Woolsey rebuild that got new ductwork installed quickly and isn’t performing, or an addition or ADU that needs new supply and return runs tied into the existing system. Either way, the work is more involved than what you’d see in a flat suburban tract. Canyon and hillside homes have complex, multi-zone layouts routed around steep split-level framing, and that makes access harder.

New ductwork installation in Malibu typically runs $1,600 to $3,200 depending on the number of zones, access difficulty, and whether we’re working around finished spaces. That’s a whole-system range, quoted in writing before work begins. We don’t surprise you with a larger invoice once the van is parked.

Post-Rebuild Systems That Weren’t Done Right

We’ve run camera inspections in Malibu homes rebuilt after 2018 and found brand-new flex duct crimped at tight turns, disconnected from boots, or never sealed at the plenum. The construction pace after Woolsey was fast, and some HVAC subs took shortcuts. If a rebuilt home has uneven temperatures or a whistling noise, a ductwork inspection almost always finds the answer.

Tying In New ADUs and Additions

Malibu has seen a wave of ADU construction in Point Dume, Malibu Park, and the flats near Zuma. Tying that new space into the existing system means calculating the added load, running properly sized supply lines, and installing a return that actually pulls air back. A missing or undersized return is the most common mistake we fix.

Trusted Brands We Service in Malibu

We work on every major ductwork brand you’ll find in Malibu homes, from original mid-century sheet metal to modern flexible duct from Rotobrush and Nikro equipment we use for source removal. When air quality is the issue, we work with products from Aprilaire and Abatement Technologies for filtration and surface treatment. And we carry common replacement parts in our vehicles, so a simple fix doesn’t turn into two trips down PCH. Stocking local parts for Malibu means we finish more jobs same-day.

Common Air Duct Repair Problems We See in Malibu Homes

• Crushed or disconnected original ductwork: Decades of remodels and re-steps in 1950s-70s beach cottages off Broad Beach Road and Las Flores Canyon have flattened metal trunk lines and pulled flex duct loose. The back rooms stop getting air and the blower motor runs harder, which shortens its life.
• Woolsey-era soot still inside duct walls: Homes a mile or more from the 2018 fire perimeter often show heavy black combustion soot bonded to the interior walls of supply and return runs, and on the filter housing. The air handlers ran for days on hazardous-AQI outside air, and many systems were never remediated. That residue circulates every time the fan runs.
• Salt-air corrosion in marine-layer homes: Homes along PCH, especially in eastern Malibu and near the Lagoon, get Pacific air moving through duct openings. Salt accelerates corrosion on metal components, and the persistent May-through-July marine layer keeps humidity high enough for mold to colonize the interior of ducts.
• Leaking joints in crawlspaces: We regularly find duct seams in beach homes that have been leaking into the crawlspace for decades. The joints separate, the conditioned air goes under the house, and the homeowner pays to cool the sand. Sealing with mastic is often the single highest-return repair we do.
