We’ve been driving up to San Francisco from Los Angeles for scheduled multi-unit jobs for years, and we know the city’s housing stock like our own tools. From the steep hillside Victorians of Russian Hill to the converted warehouse lofts in SoMa, San Francisco presents dryer vent problems you won’t find in newer inland cities. The angled vent caps on brick facades, the shared shafts in Mission District apartment buildings, the original foil-flex ducts hidden behind built-in cabinetry in 1906-rebuild flats - we’ve cleared them all. Our Dryer Vent Cleaning team arrives when we say we will, and we don’t leave until the camera shows a clean run.
Why Bellows Air Duct & Vent Co. Is San Francisco’s Preferred Dryer Vent Cleaning Company
San Francisco homeowners have called us back for 42 years because we treat their houses with the care we’d want for our own. We’re not a coupon company that sends a different subcontractor every time. Our technicians are background-checked, uniformed, and trained on the specific failure modes of Bay Area housing: fog corrosion, salt condensation, and the access nightmares of retrofit ductwork in century-old flats.
Ray Castillo, who leads Bellows, insists on the same standard on every San Francisco job: camera inspection before and after, upfront pricing disclosed before a single tool is lifted, and our 90-Day Done Right Promise stamped on every invoice. If it’s not right, we make it right. No paperwork, no arguing. That’s been our way since 1984.
Calls are answered by a live person, 24 hours a day. Not a voicemail tree, not an app. When your dryer is backing up moisture into a fog-damp flat in the Outer Richmond, you want to talk to someone who can dispatch help, not leave a message and hope.
Our Dryer Vent Cleaning Services in San Francisco
Dryer Vent Inspection
Every San Francisco job starts with a camera. We run a high-resolution inspection camera through the full vent run to locate blockages, corrosion, and hidden damage before we quote a dollar. In Victorian and Edwardian flats throughout Nob Hill, the Tenderloin, and North Beach, we regularly find original galvanized caps that have rusted shut from decades of fog exposure, or flexible transition ducts kinked behind built-in cabinetry that hasn’t moved since the 1970s. The inspection takes 15-20 minutes and gives you a visual record, not a guess.
Vent Cleaning and Lint Removal
San Francisco’s cool marine climate creates a specific problem: fog-driven condensation inside uninsulated attic vent runs wets the lint, which then hardens into rock-like blockages. A standard brush cleaning won’t touch these. We use Rotobrush and Nikro professional-grade equipment with aggressive whipping heads and HEPA containment to break up hardened lint deposits, then extract them completely. In hillside homes from Russian Hill to Telegraph Hill, where vent runs can stretch 25-35 feet through multiple bends, this thoroughness matters. Wet lint is a fire hazard. Hardened wet lint is a fire hazard that’s harder to remove.
Vent Rerouting
Many San Francisco dryer vents were never routed correctly to begin with. Retrofit installations in Victorian flats often force the vent through multiple 90-degree bends, or run it through unheated crawl spaces where condensation pools. We reroute vents to the shortest practical path with minimal bends, using rigid aluminum duct where code allows. For SoMa loft conversions with industrial-grade rooftop units, we sometimes need to run new vent paths through open floor plates to reach exterior walls. Rerouting in San Francisco typically runs $225-$425, including materials and labor. We’ll show you the camera footage of the old path and explain exactly why the new one works better.
Vent Cap Replacement and Bird Guard Installation
San Francisco’s salt-laden fog destroys standard vent caps. We recently cleaned a dryer vent in a Nob Hill Edwardian flat off California Street where the original 1950s galvanized vent cap had rusted shut from decades of fog exposure, causing the dryer to fail safety shutoff. We replaced it with a stainless-steel Guardsman cap with a bird guard, then cleared a lint plug in the flexible transition duct that had formed where the vent narrowed behind the wall.
We stock corrosion-resistant caps rated for marine environments, with built-in bird guards that keep pigeons and gulls out without restricting airflow. Standard cap replacement runs $89-$165 installed; bird guard upgrades add $35-$55.

Trusted Brands We Service in San Francisco
We build our van stock around the brands that serious HVAC contractors specify: Rotobrush and Nikro for duct cleaning and agitation equipment, Abatement Technologies for HEPA containment and air scrubbing, and Guardsman for vent caps and termination hardware. For San Francisco’s fog-damaged systems, we carry stainless-steel and marine-grade aluminum caps that outlast the galvanized hardware sold at big-box stores. Most replacement parts are on the van, so we’re not making a second trip while your laundry piles up.
Common Dryer Vent Cleaning Problems We See in San Francisco Homes
- Fog-hardened lint blockages in hillside attic runs. In North Beach and Russian Hill, uninsulated vent runs through steep attic spaces collect condensation from the marine layer, wetting lint until it hardens into dense plugs. Standard brushing won’t remove these; we use aggressive mechanical agitation followed by vacuum extraction.
- Corroded vent caps sealed shut by salt fog. The angled nozzles on brick and stucco facades throughout Pacific Heights, the Marina, and the Richmond District trap salt-laden condensate. Original galvanized caps rust solid in 10-15 years. We replace them with stainless-steel Guardsman caps rated for coastal exposure.
- Grease-contaminated lint in shared Mission District shafts. In the dense mixed-use corridors of the Mission, residential dryer vents often share wall cavities or courtyard shafts with commercial kitchen exhaust. Technicians find sticky lint plugs bonded with cooking grease, requiring chemical degreasing before mechanical cleaning can work.
- Hidden kinks in original foil-flex behind built-in cabinetry. In 1906-rebuild flats throughout the Tenderloin and SoMa, original foil-flex ducts were run through spaces never engineered for access. Kinks behind permanent cabinetry trap lint for decades, creating fire hazards that only camera inspection reveals. Partial access work may be needed.

FAQs - Dryer Vent Cleaning in San Francisco
The summer fog cycle is actually worse for vent clogging than winter rain. From June through September, Karl the Fog rolls in heavy each morning, condensing on the cool metal interior of your vent run. That moisture wets lint particles, which then compress and harden as the day warms. By August, we’ve pulled rock-hard lint cylinders from vents in the Sunset and Richmond that started as normal soft lint in May. The pattern is so consistent in San Francisco that we recommend mid-spring cleaning as preventive maintenance. Call (844) 685-6342 to schedule before the hardening starts - estimates are free.
No, and we won’t do it. San Francisco Fire Code prohibits dryer venting through chimneys or any flue shared with combustion appliances, and the dense SRO buildings of the Tenderloin are specifically high-risk for fire spread. We’ve inspected too many improvised installations where lint accumulated in chimney flues that also served gas water heaters. The correct solution is a dedicated vent path to exterior air, which we can install with proper clearances and a stainless-steel cap. Call (844) 685-6342 for an assessment of your specific layout - estimates are free.
Exterior vent cap replacement on a single-family home typically does not require a permit in San Francisco. In condos and multi-unit buildings, the answer depends on your HOA rules and whether the cap is on a common wall or your exclusive-use exterior. We’ve worked with building managers throughout SoMa and the Mission to coordinate access and documentation. We can advise on your specific situation before we quote. Call (844) 685-6342 and we’ll walk through it - estimates are free.
Every 12-18 months for SoMa loft conversions, and more frequently if you run commercial-grade or stacked laundry equipment. These buildings present a unique combination: long vent runs across open floor plates, rooftop HVAC environments that expose ducts to temperature swings, and industrial-grade dryers that move more lint than standard residential units. The 2005-era conversions on Townsend and Brannan particularly show accelerated lint buildup where original vent paths weren’t redesigned for residential use. We recommend annual camera inspection with cleaning as needed. Call (844) 685-6342 to set a schedule - estimates are free.
A properly specified bird guard will not measurably restrict airflow. The Guardsman caps we install are engineered with louvered or mesh openings that exceed the free area of standard flapper caps. In San Francisco’s fog environment, the real airflow killer is corrosion and lint accumulation on the cap mechanism itself, which a bird guard actually reduces by preventing birds from nesting in the termination. We’ve measured airflow before and after installation on dozens of San Francisco jobs; the improvement comes from the clean, corrosion-free cap, not despite the guard. Call (844) 685-6342 if you’re concerned about your specific dryer model - estimates are free.
