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.

We’ve worked in enough Sausalito homes to know the difference between standard dust removal and what this town actually needs. The marine layer here doesn’t burn off the way it does in Mill Valley or Corte Madera. It lingers. That persistent humidity changes what’s growing inside your ducts, and it changes how a cleaning has to be done if you want the results to last.
Why Kestrel Air Duct Cleaning Is Sausalito’s Preferred Air Duct Cleaning Company
Our reputation in Sausalito was built on showing up in the window we promised and leaving the written price unchanged. The Kingswell Guarantee, which has governed every job since our founding in 2004, requires four things: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee with a free return visit if the work fails within the guarantee period. We don’t soften any of them.
Sausalito homeowners call us back because we answer the phone with a live person, 24/7. Not a queue. Not an automated system. A real conversation about what you’re seeing and smelling from your vents. Our technicians are background-checked, uniformed, and trained on the specific failure modes this coastline produces: salt-corroded flex-duct connectors, chronic condensation in undersized mid-century runs, and mold recolonization that surface cleaning alone won’t stop.
We know the local terrain. The steep crawl spaces below homes in the Banana Belt. The floating-home docks off Bridgeway where the bay is literally beneath the floor. The 1940s-1960s hillside stock with original ductwork routed through spaces a standard vacuum hose can’t navigate. This isn’t generic Marin County knowledge. It’s Sausalito-specific, and it affects what we bring on the truck and how we scope the job.
Residential Air Duct Cleaning in Sausalito
Residential Air Duct Cleaning in Sausalito addresses the full supply and return network in single-family homes, condominiums, and the internationally known floating-home community on Richardson Bay. A typical residential job in Sausalito runs $380-$680 for a complete system cleaning, with pricing shaped by home size, duct accessibility, and whether video inspection reveals corrosion or disconnection requiring repair. Most hillside homes in neighborhoods above Caledonia Street or along Prospect Way need attention to mid-century ductwork that was undersized even when it was new, now further compromised by decades of moisture exposure.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull it back. In Sausalito’s humid environment, both sides accumulate moisture-loving microbial growth that standard vacuuming won’t dislodge. We use Rotobrush rotary brush agitation to scrub debris from the duct walls, then Nikro negative-pressure extraction to pull it out of the system entirely. Abatement Technologies HEPA filtration keeps those loosened particles out of your living space during the process.
Full System Cleaning with Video Inspection
Our video inspection goes in before the brushes. In Sausalito’s older hillside homes, we’ve found crushed flex runs and disconnected joints that homeowners didn’t know existed. On the floating homes, we document connector corrosion and liner degradation from salt air. You see the footage. We explain what it means. Then we clean, repair, or seal based on what we actually found, not what we assumed.
Commercial Air Duct Cleaning in Sausalito
Commercial Air Duct Cleaning in Sausalito serves restaurants along Bridgeway, professional offices, retail spaces, and the smaller lodging properties that draw tourists to the waterfront. A typical commercial job in Sausalito runs $650-$1,400 depending on system complexity, square footage, and whether the property operates under Marin County health department ventilation requirements. We schedule around your business hours and provide the documentation needed for compliance records.
Restaurant and Food-Service Ventilation
Kitchen exhaust and makeup air systems in Sausalito’s dining spots face the same salt-air corrosion as residential ducts, with the added load of grease and particulate. We clean the full path from hood to fan, documenting the work for county inspection. Our technicians arrive in uniform, work within your prep and service windows, and leave the site cleaner than they found it.
Office and Retail System Maintenance
Commercial HVAC in Sausalito’s smaller buildings often shares the same mid-century infrastructure as the residential stock, with systems that were never designed for modern occupancy loads. We assess airflow, identify restriction points, and clean without disrupting your operations. The written price is in your hands before a single vent is touched.
Trusted Brands We Service in Sausalito
We clean ductwork connected to every major HVAC brand, and we stock filtration and indoor-air-quality products from Aprilaire, Abatement Technologies, and Guardsman for Sausalito customers who want to maintain cleaner air between service visits. Aprilaire media air cleaners upgrade standard filter slots to capture smaller particles. Abatement Technologies portable HEPA units supplement your HVAC filtration during renovation or allergy season. Guardsman products address specific IAQ concerns we see repeatedly in this coastal climate. If your system needs a component we don’t carry, we source it fast through our Bay Area supply relationships rather than leaving you waiting.
Common Air Duct Cleaning Problems We See in Sausalito Homes
- Mold recolonization in floating-home ducts within one to two years of cleaning. The salt-laden bay air penetrates every unsealed joint, and moisture from the water below keeps humidity levels inside ductwork high enough for continuous microbial growth. A standard cleaning without connector replacement and sealing just resets the clock.
- Crushed or disconnected runs in hillside mid-century crawl spaces. Ductwork from the 1940s-1960s was often routed through steep, cramped spaces with inadequate support. Over decades, sections collapse or separate entirely. Without video inspection, a cleaning crew vacuums the accessible parts and misses the real problem.
- Condensation pooling in undersized supply ducts. Sausalito’s persistent marine layer keeps relative humidity elevated even when thermostats read comfortable temperatures. Undersized ducts move air too slowly to clear moisture, creating chronic damp zones that feed mildew.
- Corroded flex-duct connectors at the plenum. Salt air attacks the metal and polymer connections between duct sections. We’ve replaced connectors on floating homes that were structurally degraded after just a few seasons of exposure, a failure mode essentially absent from hillside homes a few blocks inland.
Pricing for Air Duct Cleaning in Sausalito, CA
Most Sausalito homes fall between $380 and $680 for a complete residential air duct cleaning. Commercial properties typically run $650-$1,400. What moves you within those ranges: the number of supply and return vents, whether your ductwork is accessible or buried in a steep hillside crawl space, and whether video inspection reveals corrosion, disconnection, or mold that requires repair beyond standard cleaning.
We don’t quote per-vent. We don’t bait with a low coupon and revise upward once the truck is in your driveway. The written price for your complete system is in your hands before a single vent is touched. That price covers the full job: agitation, negative-air extraction, HEPA-contained removal, and before-and-after photos of your own ducts. If we find something unexpected during inspection, we show you the footage and quote the repair separately. You approve it or you don’t. No surprises.
Call (469) 972-3151 for a free estimate. We’ll ask about your home’s location in Sausalito, the age of your HVAC system, and what you’re experiencing. Then we’ll give you a real number you can plan around.

FAQs About Air Duct Cleaning in Sausalito
Floating homes sit with open water directly beneath the floor, so duct systems experience near-constant moisture intrusion and salt-laden air that penetrates every unsealed joint. Hillside homes a few blocks inland face humidity too, but without the direct bay exposure, mold cycles are typically slower and connector corrosion far less severe. Call (469) 972-3151 for an exact quote on your property - estimates are free.
No, not if the underlying moisture source hasn’t been fixed. On Sausalito’s waterfront and floating homes, fogging without sealing corroded connectors and addressing salt-air intrusion means mold returns within a year. Source removal with proper agitation, extraction, and physical repair of degraded components lasts longer than any chemical coating. Call (469) 972-3151 for an exact quote - estimates are free.
Sausalito’s marine layer rolls in off Richardson Bay and the Pacific for much of the year, rarely burning off fully inland the way it does in neighboring Mill Valley or Corte Madera. That sustained high relative humidity keeps condensation forming inside duct runs, which accelerates microbial growth and can shorten the effective cleaning interval for coastal properties compared to drier inland locations. Call (469) 972-3151 for an exact quote on your home’s needs - estimates are free.
Yes. Homes from the 1940s-1960s in Sausalito’s hillside neighborhoods often have original or partially updated ductwork routed through steep, cramped crawl spaces. The runs are frequently undersized by modern standards, and decades of moisture exposure have degraded supports and connections. Without video inspection, a standard cleaning misses crushed sections and disconnections that are invisible from the vents. Call (469) 972-3151 for an exact quote - estimates are free.
A legitimate cleaning follows NADCA ACR standards: source removal through mechanical agitation, negative-air extraction to contain debris, and HEPA filtration to protect indoor air quality during the process. In Sausalito’s humid climate, we add connector inspection and sealing specific to salt-air corrosion. The Kingswell Way requires our technicians to show you the before-and-after footage, put the guarantee in writing, and leave the site cleaner than they found it. Call (469) 972-3151 for an exact quote - estimates are free.
