Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Air Duct Repair Across Topanga
Air duct repair in Topanga usually means one of three things: a disconnected or crushed run, a rodent-chewed branch, or failing original insulation from the 1960s and 70s. Most jobs run between $350 and $1,400 depending on what we find when the camera goes in. If you’re calling from Topanga, we coordinate scheduling from our Los Angeles office and send a technician who knows canyon homes, not just tract houses. Call (980) 447-2498 and a live person answers, day or night.
Why Linden Air Duct Cleaning Is Topanga’s Preferred Air Duct Repair Company
Topanga homes are not like the rest of Los Angeles. Our techs have worked in post-and-beam cabins off Old Topanga Canyon Road, converted weekend retreats along Topanga Canyon Boulevard, and hillside homes near Fernwood and the Post Office area. We know what happens when decades of Santa Ana winds push chaparral ash into crawlspace duct runs. We know what rodent damage looks like in a house that sat unoccupied for years before someone made it a full-time residence.
Marcus Veale leads our repair team, and every technician who arrives at your door is background-checked, identity-verified, and photo-badged under the Threshold Standard. You get the tech’s name and photo before the visit. You see a photo ID at the door. No exceptions, no matter how remote the property.
Every repair we perform in Topanga carries a written 365-day guarantee. If the repair doesn’t hold, we return at no charge. The price is in writing before any work starts. That’s not a promotion. It’s how we’ve operated since 2004.
Air Duct Replacement in Topanga
Air Duct Replacement in Topanga is rarely about swapping like for like. The original flex duct in a 1960s cabin was never sized for a full-time household running HVAC year-round. When we replace runs here, we rebuild them with sealed rigid duct where the crawlspace allows, and we re-balance airflow at the air handler so every register actually delivers.
A single-room replacement, where one branch has failed, typically runs $350 to $700. Replacing most or all of the accessible ductwork in a Topanga home is $1,200 to $2,800 depending on crawlspace access, run length, and whether asbestos-wrapped insulation on old supply lines must be abated before we touch anything.
When Replacement Beats Repair
If the existing flex duct is kinked, collapsed, or has been chewed through in multiple places, patching becomes a losing game. We tell you straight: sometimes rebuilding a run is cheaper over three years than chasing leaks.
Material Identification First
In pre-1980 Topanga structures, some supply lines have asbestos-wrapped insulation. We inspect and identify materials before any cleaning or repair work begins. If abatement is required, we coordinate it properly rather than agitating something dangerous.
Ductwork Repair in Topanga
Ductwork Repair in Topanga usually comes down to three problems: disconnected collars where an owner spliced in a run decades ago, rodent-chewed branches behind registers, and sagging flex that starves half the house of airflow. The fix involves reconnecting and sealing, replacing damaged sections, and sometimes adding support strapping so a run doesn’t sag again.
Reconnecting and sealing a single disconnected branch costs $180 to $325. Rebuilding a damaged section with new rigid or flex duct runs $400 to $900. If we’re repairing multiple branches and re-balancing returns, expect $750 to $1,400.
Sealing Is Part of the Repair
We don’t just reconnect a run and leave the gaps. Every joint gets sealed with mastic or foil tape rated for HVAC use. A repair that leaks is not a repair.
Tight Attics, Tight Crawlspaces
Topanga attics and crawlspaces are notoriously tight. Non-standard framing in converted cabins means we work carefully, often by hand, rather than forcing equipment where it doesn’t belong. That’s slower. It’s also the only honest way to do it.
Trusted Brands We Service in Topanga
We work on all major HVAC and duct brands, and we stock common replacement parts for the systems Topanga homeowners actually have. That includes Rotobrush and Nikro equipment for cleaning and inspection, plus air-quality products from Abatement Technologies and Guardsman where a repair warrants an upgrade. Stocking parts locally means fewer return trips and faster turnaround when a Topanga job requires a specific collar, damper, or support bracket. If your system needs something unusual, we’ll tell you before ordering, not after.
Common Air Duct Repair Problems We See in Topanga Homes
- DIY-modified flex runs that sag and kink. Converted weekend cabins often have runs an owner spliced in themselves forty years ago. The duct sags between joists, kinks at the bend, and airflow drops to nothing at the far register.
- Rodent-chewed and ash-packed branches. When a Topanga home runs on wood stoves and passive cooling for most of the year, the ducts sit unused. Rodents nest in them. Ash from multiple fire seasons settles in layers.
- Disconnected collars at the air handler or register boot. Old tape dries out and fails. The run separates. Conditioned air dumps into the crawlspace while the bedroom stays cold.
- Crushed flex under stored belongings. In homes where attic or crawlspace storage is common, heavy boxes crush flexible duct. The repair involves removing damaged sections and installing rigid duct where practical.

FAQs About Air Duct Repair in Topanga
It depends on what the camera inspection shows. If the original ducts are metal supply lines with intact connections, we can often repair, clean, and seal them. If the flex duct is original, collapsed, or rodent-damaged in multiple places, replacement is usually the honest answer. We’ll show you the camera footage and explain the recommendation before quoting. Call (980) 447-2498 for an inspection.
Yes. Topanga’s canyon orientation channels Santa Ana winds through the community, pulling chaparral ash and fine smoke particulates into HVAC intakes even when fires are miles away. Homes that run their HVAC during Red Flag Warning days can saturate ductwork with combustion particles in a single event. The Woolsey Fire left many Topanga homes with ductwork that still holds toxic combustion residue. A repair after fire exposure often includes smoke and soot remediation, not just new connections. Call (980) 447-2498 and we’ll assess what your ducts actually absorbed.
We inspect with a camera to map the runs and identify materials. Then we work by hand where equipment won’t fit, which is most Topanga attics. We remove damaged sections, rebuild with sealed rigid or flex duct, reconnect at the collar and register boot, seal every joint, and test airflow at each register. The work is slower than a tract-home job, and that’s the point. Call (980) 447-2498 for a written quote.
If some rooms get strong airflow and others get almost none, you need a repair. If every register delivers weak but balanced airflow, you probably need a cleaning. If you see dust blowing from one vent but not others, or hear rattling inside a wall cavity, that’s a disconnected or damaged run. Schedule an inspection and we’ll diagnose it properly at (980) 447-2498.
We seal every joint with mastic or HVAC-rated foil tape. A repair that isn’t sealed leaks conditioned air into the crawlspace or attic on day one. Sealing is part of the job, not an add-on. The 365-day guarantee covers the repair and the seal. If anything fails within a year, we come back at no charge. Call (980) 447-2498 to schedule.
We coordinate scheduling from our Los Angeles office and serve Topanga regularly. Most repair visits can be scheduled within a few days, depending on your availability and the scope of work. Every job begins with a written estimate, so you’ll know the plan before equipment comes off the truck. Call (980) 447-2498 and a live person will confirm the next available slot.
