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.

AfterAir Duct Cleaning Company in Sausalito, CA
Air duct cleaning in Sausalito runs $350 – $650 for a typical whole-home system, with most jobs scheduled within a week and completed in a single visit. Sausalito’s hillside homes present conditions we don’t see inland: retrofit ductwork squeezed into 19th-century framing, salt-laden marine air corroding metal runs, and crawl spaces so tight that every job starts with a structural assessment before we touch a vent cover. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we dispatch crews from our San Francisco Bay Area office to work in Sausalito specifically. Call (361) 326-5060 for a written estimate before any work begins.
Why Sausalito Homes Are Different
Sausalito’s building stock is unlike anything five miles inland. The city sits on steep hillsides above Richardson Bay, with a dense concentration of wood-frame homes built between the 1880s and 1940s, many originally heated by coal or oil and later retrofitted for forced air. That retrofit history matters: ductwork was often installed in whatever space was available, running through unsealed floor joists above open crawl spaces, mixing rigid metal with flex duct and foil-wrapped runs that were never permitted or inspected to modern standards.
The coastal fog belt compounds the problem. Sausalito’s marine layer keeps relative humidity high year-round, pushing salt-laden moisture into crawl spaces and wall cavities where metal ducts corrode and fiberglass liners grow mildew. Because temperatures stay mild, HVAC systems here run more for air circulation and filtration than for heating or cooling, meaning ducts act as continuous conduits for moisture and allergens rather than seasonal equipment. We’ve found rodent nesting in floor framing above open crawl spaces, condensation pooling in low spots where ducts sag, and salt-air corrosion eating through metal runs that would last decades in drier climates. Every Sausalito job we take starts as much as a diagnostic survey as a cleaning.
Our Main Sausalito Services
Most Sausalito homeowners who call us need one of these three services. Each has its own page with full pricing, process details, and Sausalito-specific conditions.
Air Duct Cleaning in Sausalito
Our full-system cleaning uses a Rotobrush rotary brush system and Nikro negative-air machine to pull debris from every accessible run. In Sausalito, that means navigating tight crawl spaces, identifying unpermitted junctions, and treating mold-prone areas with extra attention. We photograph the interior of your ducts before and after so you see what came out. Air Duct Cleaning in Sausalito
Dryer Vent Cleaning in Sausalito
Dryer vents in Sausalito’s older homes often run through exterior walls with minimal clearance or terminate under decks where lint accumulates in damp conditions. We clear the full run from appliance to termination, test airflow with a manometer, and flag any fire-safety issues. Most Sausalito dryer vent cleanings take 60 – 90 minutes.

Duct Sealing in Sausalito
Unsealed ducts in Sausalito’s retrofit systems leak conditioned air into crawl spaces and pull musty, salt-laden air back into living areas. We apply duct sealing mastic and mechanical fasteners at every joint, then pressure-test the system to verify results. For homes with Aprilaire or Honeywell filtration, sealed ducts mean the equipment actually filters what you’re breathing. Duct Sealing in Sausalito
