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 Cleaning Across Larkspur
Air duct cleaning in Larkspur typically runs $450-$850 for a complete residential system, with most jobs scheduled within a few days and completed in a single visit. We’re Morton’s Air Duct Cleaning, and our crews work the canyon neighborhoods, the Landing condos, and the downtown cottages regularly - not as outsiders guessing at Marin conditions, but as technicians who understand how Baltimore Canyon’s redwood canopy changes what “clean ducts” actually means here. Dispatch and scheduling are coordinated from our San Francisco Bay Area office, and we’ll give you a written price before any work starts, every time. Call (323) 918-4345 for a free estimate.
Why Morton’s Air Duct Cleaning Is Larkspur’s Preferred Air Duct Cleaning Company
We’ve been part of the Cedarwell family since 2005, and our reputation in Larkspur has been built job by job - mostly through neighbors telling neighbors after watching our crew lay drop cloths across a Madrone Avenue hardwood floor before touching a single register. Paul Adeyemi leads our operation, and the feedback we hear most from Larkspur customers is that we noticed what other crews didn’t: the damp flex jacket in the crawl space, the shared dryer vent stack at the Landing, the way Corte Madera Creek fog changes what grows inside ducts here.
Our response time to Larkspur is typically within the week for standard scheduling, and we carry the full range of Rotobrush and Nikro equipment needed for both the tight crawl spaces under 1920s Craftsman bungalows and the multi-unit systems at Larkspur Landing. Every technician is background-checked, arrives in uniform, and works to the Cedarwell C.A.R.E. values - shoe covers inside, quiet tools during nap hours, and pet-safe product choices where available. We don’t rush. We don’t surprise you on the invoice. And we don’t leave until we’ve sent you a photo of the clean-up.
Ductwork Cleaning in Larkspur
Ductwork Cleaning in Larkspur is not a one-size-fits-all service because the duct systems here vary dramatically by neighborhood. In Baltimore Canyon and Madrone Canyon, we’re often cleaning flex duct that was retrofitted into 1910s-1940s wood-frame cottages and bungalows, with runs shoehorned through wall cavities and crawl spaces never designed for forced air. At Larkspur Landing, we’re working with 1980s-era condominium systems whose original flex duct and duct board is now past its 30-to-40-year service life. A typical whole-system Ductwork Cleaning in Larkspur runs $450-$850 for residential properties, with commercial and multi-unit systems quoted individually after inspection.
Moisture-Driven Contamination Protocol
Our crews start with a moisture assessment, not just a vacuum pass. The perpetual shade from redwood and bay laurel canopy keeps crawl-space duct jackets damp year-round, so we inspect the exterior condition of flex runs before we ever look at interior surfaces. If we find outside-in degradation, we’ll show you the camera footage and explain whether cleaning, repair, or replacement makes sense for your system.
Multi-Unit Coordination
Larkspur Landing condos and similar shared buildings require scheduling that respects building management and neighboring units. We coordinate access to shared risers and stack dryer vents, and we provide written scope and pricing for both individual unit work and building-wide maintenance plans.
Air Duct Inspection in Larkspur
Air Duct Inspection in Larkspur should happen before any cleaning work is quoted, especially in the canyon neighborhoods where moisture damage often hides from view. Our inspection process uses camera-equipped tools from Nikro and Abatement Technologies to document the interior condition of supply and return runs, the air handler, and the plenum connections. We also assess the exterior condition of flex duct jackets in crawl spaces and attics, looking for the darkened, musty outer layers that redwood drip causes. A typical residential Air Duct Inspection in Larkspur costs $150-$250, and we apply that fee toward your cleaning if you proceed with the work.
What the Camera Reveals
Homeowners are often surprised by what we find. A 1990s HVAC retrofit in a seemingly “newer” canyon bungalow can still have flex duct with degraded outer jackets, or supply runs with organic debris from years of spore infiltration. The camera doesn’t lie, and we share the footage with you before recommending any next steps.
Written Report and Pricing
Every inspection concludes with a written condition report and a single flat price for any recommended work. No per-vent add-ons. No surprises once the crew is on site. You’ll know exactly what we’ll do and exactly what it costs before we start.
Trusted Brands We Service in Larkspur
We clean and maintain systems built around Honeywell, Aprilaire, and Abatement Technologies components, and we carry common parts and media for these brands on our Larkspur-area vans. That means faster turnaround when your system needs more than cleaning - a failed Aprilaire media cabinet, a Honeywell electronic air cleaner cell, or an Abatement Technologies HEPA filtration upgrade. Our primary cleaning equipment comes from Rotobrush and Nikro, industry-trusted names that produce the agitation tools, negative-pressure systems, and HEPA vacuums we use in your home. We don’t rent entry-level gear. We own professional equipment and maintain it to manufacturer spec, because the quality of the clean depends on the quality of the tools.
Common Air Duct Cleaning Problems We See in Larkspur Homes
- Outside-in flex duct degradation in canyon homes. Technicians working Baltimore Canyon jobs routinely find flex duct insulation visibly darkened and musty on the exterior from redwood and bay laurel drip, while the interior still appears clean. Homeowners with 1990s HVAC retrofits assume their system is “newer” and skip inspection.
- Rebound contamination from partial cleaning. A crew cleans the visible supply registers in a Madrone Avenue cottage but leaves the damp crawl-space return runs untouched. Within weeks, spores and mildew migrate back into the cleaned sections because the source was never addressed.
- Shared stack dryer vent blockages at Larkspur Landing. 1980s-era condominiums with original duct board and shared risers require coordinated building access. One-unit-at-a-time service misses the common blockage points and can actually push debris into neighboring units.
- Undersized return pathways in retrofitted Craftsman homes. Original wall cavities converted to duct chases in 1920s bungalows often lack proper sealing and insulation, pulling humid crawl-space air directly into the system and accelerating biological growth.
Pricing for Air Duct Cleaning in Larkspur, CA
Most residential air duct cleaning jobs in Larkspur fall between $450 and $850 for a complete whole-system clean, including supply ducts, return ducts, air handler, and registers. Commercial systems and multi-unit buildings are quoted individually after inspection, typically starting around $1,200. What moves you within that range: the number of air handling zones, accessibility (crawl space vs. basement vs. attic), whether we find degraded flex duct requiring repair or replacement, and whether you add dryer vent cleaning to the scope. We do not price per vent. We give one flat price per system, agreed in writing before any work starts. Every estimate is free, and every inspection fee is credited toward work if you proceed. Call (323) 918-4345 to schedule yours.

FAQs About Air Duct Cleaning in Larkspur
The redwood and bay laurel canopy in Baltimore Canyon and Madrone Canyon creates chronically damp conditions that accelerate mold and biological growth inside duct systems. Larkspur’s geographic pocket traps marine fog through the Corte Madera Creek corridor, and the surrounding hills prevent afternoon drying that inland Marin cities experience. That persistent moisture infiltrates ducts through leaky connections and keeps crawl-space flex duct jackets damp year-round, a failure mode sunnier San Rafael or Novato crews rarely encounter. If you live in the canyons, we recommend inspection every 2-3 years rather than the standard 3-5 year interval. Call (323) 918-4345 to schedule.
Yes, and we prefer to coordinate with building management rather than work around neighbors. Larkspur Landing’s 1980s-era buildings have stack dryer vents and shared risers that require scheduled access to common mechanical areas. We provide written scope and timing to your HOA or property manager, and we clean the full stack from the roof cap down to prevent pushing debris into adjacent units. One-unit-at-a-time service often misses the common blockage points and can create complaints. Call (323) 918-4345 and we’ll walk you through the coordination process.
You probably can’t tell from the supply registers alone. In our field experience, 1990s flex duct in canyon bungalows often shows visible darkening and mustiness on the exterior jacket from redwood and bay laurel drip while the interior still reads clean on a casual look. The only reliable method is camera inspection through the full duct run, plus a moisture assessment of the crawl space or attic cavity where the duct lives. We find this outside-in degradation pattern so consistently in Baltimore and Madrone canyons that we lead every canyon job with inspection, not assumptions. Call (323) 918-4345 for a camera inspection.
A proper job starts with protecting your floors and furniture with drop cloths, then running a camera to document pre-cleaning conditions. We connect a negative-pressure HEPA collection system to the air handler, agitate debris from each supply and return register with Rotobrush or Nikro tools, and clean the air handler cabinet, blower, and coil if accessible. In canyon homes, we also inspect the exterior condition of crawl-space flex duct for moisture damage. The job ends with a photo of the clean-up and a final camera pass so you can see the difference. Written price before we start, every time. Call (323) 918-4345 to book.
Yes, and they require technicians who understand what they’re looking at. Downtown Larkspur and the canyon neighborhoods contain many 1910s-1940s wood-frame homes where forced air was retrofitted decades after construction, with duct runs squeezed through wall cavities and crawl spaces never designed for them. Returns are often undersized, supply runs may be uninsulated in exterior walls, and access points can be hidden behind built-in cabinetry or under original floor coverings. Our crews have worked these homes enough to know where to look and how to adapt our equipment to tight spaces without damaging original fabric. Call (323) 918-4345 and we’ll assess your specific layout.
