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 Dryer Vent Cleaning Across Larkspur
Dryer vent cleaning in Larkspur typically costs $180-$340 for a standard single-family home, and our crews complete most jobs in under two hours with the dryer ready to use that same afternoon. If your dryer is taking longer to finish loads or the laundry room carries a persistent damp smell, a clogged vent run is the likely cause, especially in Larkspur’s canyon neighborhoods where fog and tree canopy keep exterior lint wet and packed tight.
We’ve been serving Larkspur from our San Francisco Bay Area dispatch office since 2005, and our technicians know the difference between a dry, fluffy lint clog and the sodden, matted blockages that form where Baltimore Canyon and Madrone Canyon meet the redwood shade. We arrive in uniform with shoe covers and drop cloths, run a written price past you before touching anything, and leave a photo of the clean-up so you see exactly what came out. Call (323) 918-4345 when you’re ready to book, or read on to understand why Larkspur’s unique climate makes professional vent cleaning more important here than in sunnier inland Marin.
Why Morton’s Air Duct Cleaning Is Larkspur’s Preferred Dryer Vent Cleaning Company
Families in Larkspur call us back because we treat the house like it’s our own. That means shoe covers at the door, drop cloths under the work area, and quiet tools if there’s a toddler down for a nap or a dog nervous about strangers. Every technician is background-checked and uniformed, and every job carries our 365-Day Done Right Promise: if something isn’t right, we make it right, full stop.
Our written price comes before any work starts, every single time. No per-vent add-ons, no surprise charges once the van is in your driveway. We use professional equipment from Rotobrush and Nikro, not rental-grade gear, and we document the clean with a photo of the work area before we leave. A live person answers our phone 24/7, not a voicemail tree, because we know dryer problems don’t wait for business hours.
We understand Larkspur’s housing stock: the Craftsman bungalows downtown with their retrofitted duct runs, the 1980s condos at Larkspur Landing with original flex duct hitting end-of-life, and the canyon homes where bay laurel drip and perpetual shade degrade exterior vent caps from the outside in. That local knowledge means we spot failure modes other crews miss.
Dryer Vent Installation in Larkspur
Dryer Vent Installation in Larkspur runs $450-$850 for a standard through-wall or through-roof termination, with complex reroutes through finished crawl spaces or multi-story condo stacks at the higher end. Most Larkspur homeowners need new vent installation when they’re replacing an old dryer with a longer run requirement, converting from electric to gas, or correcting a dangerous foil or plastic transition that no longer meets California building code.
Our crews see two distinct installation challenges in this market. Downtown Larkspur’s vintage wood-frame cottages often have laundry areas shoehorned into spaces never designed for vented appliances, requiring careful routing through wall cavities that also carry knob-and-tube remnants or old plumbing. Larkspur Landing condos frequently need complete replacement of sagging flex duct runs that have collected condensation behind the drywall for decades.
When New Installation Makes Sense
We recommend full replacement when the existing run uses outdated materials, exceeds 25 feet in equivalent length, or has more than two 90-degree elbows that choke airflow. In Larkspur’s damp climate, every bend is a lint trap; we design straighter, smoother runs using rigid metal duct where code and structure allow.
Code Compliance and Safety
California code now prohibits plastic or thin foil transition hoses behind the dryer. Our installations use solid metal pipe with proper support straps and a listed termination cap with backdraft damper. For canyon homes where wildlife intrusion is common, we can install a bird guard that doesn’t restrict airflow.
Dryer Vent Repair in Larkspur
Dryer Vent Repair in Larkspur typically costs $150-$400 depending on whether we’re replacing a crushed transition hose, re-securing a detached exterior cap, or patching a section of damaged rigid duct in a crawl space. Many Larkspur repairs address the same root cause: moisture from fog and canopy drip has degraded the vent materials or created a lint blockage that overheated and damaged the run.
We don’t quote repair prices over the phone without seeing the job, because a “simple” cap replacement can reveal a foot of rotted duct behind the wall in Baltimore Canyon’s chronic damp. What we do promise is a written, itemized price before any work begins, and honest guidance on whether repair or full replacement is the smarter long-term spend.
Common Repair Scenarios
Crushed or kinked transition hoses behind the dryer are the easiest fix and the most dangerous to ignore. We replace them with UL-listed rigid or semi-rigid metal connectors that won’t collapse when the dryer is pushed back. Disconnected joints in crawl spaces require re-sealing with proper foil tape or mastic, never screws that catch lint.
Exterior Cap and Termination Issues
Larkspur’s redwood litter and bay laurel debris bury exterior caps under decks and eaves, especially in Madrone Canyon where dense planting meets the house. We clear the termination, verify the backdraft damper moves freely, and confirm airflow with a meter before calling the job complete.
Trusted Brands We Service in Larkspur
Our vans carry professional-grade equipment from Rotobrush, Nikro, and Guardsman, with replacement parts sized for the vent configurations common in Marin County homes. We stock rigid metal pipe in standard diameters, listed transition hoses, and bird guard assemblies that fit the 4-inch terminations used in most Larkspur residences. That local inventory means most repairs finish same-visit without a parts run to San Rafael. For condo stacks at Larkspur Landing or custom installations in renovated downtown cottages, we source from Abatement Technologies and Honeywell distributors with next-day availability when needed.
Common Dryer Vent Cleaning Problems We See in Larkspur Homes
- Wet, matted lint at the exterior termination. Because the Corte Madera Creek corridor funnels marine fog into Baltimore Canyon and Madrone Canyon and the redwood/bay laurel canopy blocks drying sun, Larkspur dryer vents terminate into chronically damp exterior air. The lint plug at the wall cap stays wet and compressed instead of drying to a fluffy, obvious clump, and many canyon homeowners don’t notice the restriction until the dryer’s thermal fuse trips.
- Degraded flex duct from the outside in. Technicians working Baltimore Canyon jobs routinely find flex duct insulation that is visibly darkened and musty on the exterior long before interior surfaces show mold. The perpetual shade and drip from overhead canopy keeps the outer jacket damp, degrading the duct material from the outside in, a failure mode that surprises homeowners who assume their 1990s HVAC is fine.
- Redwood litter and organic debris blocking terminations. Unlike inland Marin cities where dry dust is the main culprit, Larkspur’s dense tree canopy drops needles, leaves, and bark fragments that accumulate under deck-mounted caps and in soffit terminations. This debris combines with damp lint to form a nearly solid plug.
- Condensation in long horizontal runs. Larkspur Landing condos and downtown retrofits often have dryer vents routed through unconditioned crawl spaces where the persistent humidity never burns off. Water pools in low spots, accelerating rust in metal duct and collapse in older flex installations.
Pricing for Dryer Vent Cleaning in Larkspur, CA
A standard dryer vent cleaning in Larkspur runs $180-$240 for a single-family home with a straightforward through-wall termination and accessible crawl space. Condos at Larkspur Landing with longer vertical stacks or downtown Craftsman homes with convoluted retrofitted runs fall in the $280-$340 range.

What moves you toward the higher end: multiple elbows, buried terminations requiring deck access, bird guard installation, or replacement of damaged duct sections we discover during cleaning. What doesn’t affect price: the number of vents (dryers have one), square footage of the home, or a “sanitiser” fogging upsell we don’t offer because it doesn’t fix mechanical airflow problems.

FAQs About Dryer Vent Cleaning in Larkspur
The fog funnel from Corte Madera Creek and the dense redwood canopy keep exterior air damp year-round, so lint at your wall cap stays wet and matted instead of drying and blowing clear. San Rafael’s sunnier exposure lets lint dry fluffy and more obvious, prompting earlier cleaning. Call (323) 918-4345 if your dryer’s running longer than it used to.
No. A chemical mist doesn’t remove lint blockages, dry out damp duct, or improve airflow. The musty smell in Larkspur canyon homes comes from wet lint and organic debris trapped at a restricted termination, not bacteria that fogging would reach. Source removal with proper agitation and extraction is the only fix that lasts. We don’t sell fogging upsells for dryer vents.
Because the exterior flex duct and cap degrade from the outside in here. Baltimore Canyon’s perpetual bay laurel drip and trapped fog keep the outer jacket damp even when interior surfaces look clean. We’ve pulled 1990s-era duct with dark, crumbly exterior insulation and intact-looking interiors. The dryer vent is a separate system from your HVAC, and its exterior run faces harsher exposure.
Every 12-18 months for typical use, and annually if you run frequent loads or share a stack with neighbors whose lint contributes to the same duct. The 1980s-era flex duct in many Landing units is at or past its rated service life, so we also inspect for material degradation during cleaning. Call (323) 918-4345 to set up a recurring schedule.
We do not connect dryer vents to HVAC return ducts, and we flag this dangerous configuration when we find it. Dryer exhaust carries moisture, lint, and combustion byproducts that don’t belong in your air distribution system. If your Larkspur home has this setup from a past owner, we’ll quote proper separation to code.
