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.

San Anselmo sits low in the Ross Valley, where Corte Madera Creek and Sleepy Hollow Creek shape everything about how moisture moves through older homes. We’ve worked the bungalows off San Anselmo Avenue near Memorial Park, the hillside places in Sleepy Hollow, and the ranch-style houses along Sir Francis Drake Boulevard. Each neighborhood presents a different vent problem. The flats flood. The hills clog with canopy debris. The 1920s – 1940s stock has flex runs that sag and condense. We don’t treat every job the same because every job here isn’t the same.
Why Hollis Air Duct Cleaning Is San Anselmo’s Preferred Dryer Vent Cleaning Company

If the work fails within a year, we come back at no charge. No negotiation.
Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues. Scheduling is coordinated from our Bay Area office, and crews serve San Anselmo locally with the same Rotobrush and Nikro equipment we run on commercial jobs.
The Garrison Code governs how our techs behave on site: arrive inside the quoted window, price in writing, complete the job by the book, leave the site clean. San Anselmo homeowners have enough to worry about after a creek flood without chasing down a contractor who won’t document what they found.
Dryer Vent Cleaning Service in San Anselmo
Dryer Vent Cleaning Service in San Anselmo starts with knowing whether you’re dealing with routine lint accumulation or the silt-and-mold aftermath of valley flooding. A standard cleaning for a typical San Anselmo single-family home runs $180 – $340. That covers full lint removal from the transition duct, the vent run, and the exterior hood, plus airflow testing before and after. If your crawlspace took water and the vent run is compromised, we shift to documented moisture/mold protocol – camera inspection, photo logging, source removal – with replacement costs at $450 – $890 for rigid ducting installed to current code.
Camera Inspection and Documentation
We run a camera from the exterior hood to the dryer transition on every flood-affected job. The homeowner sees the footage. We save it. If an insurer needs documentation that the run was contaminated, not just lint-clogged, the photos and video are already compiled. This step is what separates a reimbursable mold claim from a denied one.
Source Removal vs. Surface Cleaning
Cleaning only the accessible segment of a sagging flex run leaves the mold source intact. We remove the compromised material, inspect the full pathway, and replace with rigid ducting where the original flex failed. No partial fixes.
Dryer Vent Installation in San Anselmo
Dryer Vent Installation in San Anselmo means building for conditions that standard suburban installs don’t face. The damp valley climate, unconditioned crawlspaces, and frequent fog drip here destroy foil flex runs in ways that dry inland climates don’t. A proper replacement runs $450 – $890 depending on length, access, and whether we’re routing through a finished basement or open crawlspace.
Rigid Ducting for Damp Crawlspaces
We spec rigid galvanized steel or aluminum ducting for San Anselmo’s lower flats, sealed at every joint with high-temperature mastic. Rigid pipe doesn’t sag, doesn’t hold condensation the way flex does, and won’t crush if a crawlspace takes water again. The slight cost increase over flex pays back in airflow efficiency and not repeating the same repair after the next winter storm.
Proper Hood and Termination
Exterior hoods in San Anselmo need to shed pollen and leaf debris from the heavy Marin canopy while keeping out driving rain. We install hoods with backdraft dampers and appropriate mesh screens, positioned to avoid the drip lines of overhanging oaks and redwoods that dominate lots in Sleepy Hollow and the hillside neighborhoods above downtown.
Trusted Brands We Service in San Anselmo
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation of stubborn lint and debris, Nikro negative-air machines for controlled extraction during mold-sensitive jobs, and filtration products from Honeywell, Aprilaire, and Guardsman. We stock common vent caps, transition fittings, and rigid duct sections for San Anselmo’s predominant housing stock – the 4-inch and 6-inch sizes found in pre-1960s homes throughout the Ross Valley. Most replacement parts are on the van, so we’re not making a second trip while your dryer sits disconnected.
Common Dryer Vent Cleaning Problems We See in San Anselmo Homes
- Flood-contaminated flex runs in the lower flats. After Corte Madera Creek tops its banks, homeowners near Memorial Park and San Anselmo Avenue often call for “lint cleaning” when the real problem is creek silt packed into a waterlogged flex run. The dryer keeps cycling moist air back into an already damp crawlspace, and mold spreads behind the walls.
- Canopy debris clogging hillside intakes. Sleepy Hollow homes under heavy oak and redwood cover see outdoor hoods packed with pollen and leaf litter every spring. The dryer runs longer, the blower motor overheats, and the homeowner blames the appliance when the vent pathway is choked.
- Condensation in unconditioned crawlspaces. Original 1920s – 1940s homes with flex runs routed through damp crawlspaces collect moisture along the entire duct length all winter. The lint turns to paste. The duct sags. The airflow drops to a trickle.
- Undersized runs on retrofitted systems. Many San Anselmo bungalows were never built for modern dryers. A 4-inch flex run stretched across a long crawlspace can’t move the CFM a current dryer needs. The appliance overheats. The clothes don’t dry. The energy bill climbs.
Pricing for Dryer Vent Cleaning in San Anselmo, CA
Standard dryer vent cleaning in San Anselmo runs $180 – $340 for a typical single-family home with accessible crawlspace or basement access. Full replacement with rigid ducting after flood damage or for failed flex runs ranges $450 – $890. Factors that move the price: run length over 25 feet, multiple turns or elbows, finished-wall access requiring patchwork, and post-storm documentation packages for insurance submission.
We give a written price before any work starts. The number on the paper is the number at checkout. No per-vent pricing, no add-ons once the van is in your driveway. If we open the crawlspace and find conditions that change the scope, we stop, show you what we found, and write a new price before proceeding. Call (361) 326-5060 for a free estimate.

FAQs About Dryer Vent Cleaning in San Anselmo
It depends on what the camera shows. If the flex run held water and shows mold growth or silt infiltration, we replace it – cleaning alone won’t pass an insurer’s documentation review or solve the moisture cycling problem. We run the inspection, show you the footage, and write a scope based on what we found, not a guess. Call (361) 326-5060 to schedule.
The heavy oak and redwood canopy in Sleepy Hollow sheds pollen and leaf debris that packs into outdoor hoods and intake grilles every spring. Downtown flats have less tree cover and more exposure to wind, so their vents stay clearer. We install hoods with better debris exclusion for hillside homes. Call (361) 326-5060 and we’ll spec the right termination for your lot.
Our package includes dated camera video of the full run, photos of contamination points, moisture meter readings where accessible, a written scope of work with unit pricing, and our technician’s signed report noting pre-existing conditions versus storm damage. Insurers want evidence that the loss was sudden and direct, not deferred maintenance. We build the file so they don’t have to ask twice.
We check three things: structural integrity of the duct material, presence of mold or organic growth beyond surface lint, and airflow recovery after mechanical cleaning. If the flex is crushed, separated, or mold-penetrated, replacement is the only fix that lasts. We document the decision criteria and show you before we cut anything. Call (361) 326-5060 for an inspection.
Yes. We spec rigid galvanized ducting with sealed joints, proper slope for drainage, and exterior hoods rated for driving rain and debris. For homes that have flooded before, we also evaluate whether the run can be rerouted through conditioned space or a less vulnerable path. The new install won’t be the same as the 1940s flex that failed. Call (361) 326-5060 for a written quote.
