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.

Our crews serve Corte Madera from our San Francisco Bay Area dispatch office, and we know the difference between a hillside home catching wind off the Tamalpais ridge and a 1960s ranch sitting on the flats where Corte Madera Marsh still breathes moisture up through the soil. That local knowledge changes how we approach the job. We’ve cleaned ducts on streets from the Cove Road area up to Christmas Tree Hill, and we’ve learned that Corte Madera’s bay-marsh geography creates problems you won’t find in inland Marin County towns. When your registers smell musty or your forced-air system seems to circulate more than just temperature-controlled air, we know where to look first.

Air Duct Cleaning Services in Corte Madera
Air Duct Cleaning Services in Corte Madera address a specific regional challenge: the combination of 1950s-1970s ranch construction on bay-fill soil and persistent marine-layer humidity that pushes mold growth inside ductwork faster than simple dust accumulation. Our process starts with a video inspection of your full system, including crawl-space runs that many homeowners never see. We then seal the system under negative-air extraction using Nikro negative-pressure units, run Rotobrush rotary agitation tools through each supply and return line to dislodge debris at the duct wall, and capture everything with Abatement Technologies HEPA filtration so loosened particles stay out of your living space. A typical residential full-system cleaning in Corte Madera runs $450 to $850.
Residential Duct Cleaning
Our residential work focuses on the complete forced-air network: supply ducts, return ducts, air handler, and blower motor compartment. In Corte Madera’s flatlands neighborhoods, we routinely find mold colonization at the supply-register boots where crawl-space humidity seeps through seams in the duct board. We clean it. We document it. We show you the before-and-after photos of your own ducts, not stock images.
Commercial Duct Cleaning
Commercial systems in Corte Madera’s retail and office spaces near Town Center require scheduled maintenance that doesn’t disrupt business hours. We coordinate access, contain our work area, and provide written certification of cleaning for property management records. Pricing scales with system complexity; most commercial quotes fall between $1,200 and $3,500.

HVAC Duct Cleaning in Corte Madera
HVAC Duct Cleaning in Corte Madera means treating the entire mechanical ecosystem, not just the visible vents. Your blower motor, evaporator coil, and return plenum can all harbor the same mold and debris that clog supply lines, especially in homes on the flats where bay air gets drawn into the return side continuously. Our technicians remove and clean the blower assembly when accessible, inspect the coil for biological growth, and verify that the return air path isn’t pulling musty crawl-space air past a filter that only catches particles, not gases or spores. Most HVAC duct cleaning jobs in Corte Madera range from $550 to $950 when the air handler requires attention.
Video Inspection
We feed a camera through your ductwork before quoting and after cleaning. You’ll see the mold bloom on the flex-duct liner. You’ll see the clean metal afterward. This isn’t a sales gimmick; it’s how we prove the work happened and how we spot vapor-barrier failures in your crawl space that would cause re-contamination within months.
Full System Cleaning
Full system means every component that moves air: supplies, returns, trunk lines, boots, plenum, blower, and filter rack. In marsh-adjacent Corte Madera homes, skipping the return side or the blower compartment leaves the largest reservoir of mold intact. We don’t do half jobs.
Trusted Brands We Service in Corte Madera
We clean ductwork connected to every major HVAC manufacturer, and we stock Honeywell and Aprilaire filtration products for Corte Madera homeowners who want to maintain cleaner air between service visits. Our Nikro negative-pressure units and Abatement Technologies HEPA systems are professional-grade tools, not box-store shop vacs with extra hoses. If your system needs upgraded filtration after cleaning, we can source and install the right Honeywell or Aprilaire media filter or electronic air cleaner for your specific unit. Most filter upgrades run $180 to $420 installed, and we size them to your actual airflow specs, not guesswork.
Common Air Duct Cleaning Problems We See in Corte Madera Homes
- Musty odors from registers with no visible water damage. In the flats near Corte Madera Marsh, crawl-space humidity penetrates duct seams and saturates fiberglass liners. The homeowner sees dry walls and assumes the ducts are fine. We pull the camera footage and show them the mold blooming inside.
- Flex-duct collapse in moisture-weakened sections. Decades of bay-fog exposure degrade the wire helix and insulation wrap in original 1960s flex runs. We document structural failure and recommend replacement when agitation would tear the duct open.
- Mold recurrence after “sanitizing” fogging treatments. Other companies have sprayed chemicals that wet the liner and feed new growth. The marsh humidity never stopped. We remove the source material mechanically instead of masking it.
- Supply-only cleaning leaving return-side reservoirs intact. Mold establishes at the blower motor and return plenum where unfiltered bay air first enters. A supply-only job leaves the colony alive and spreading back into cleaned lines.

FAQs About Air Duct Cleaning in Corte Madera
The water table stays high year-round on the former tidal marshland, and marine-layer fog pushes salt-laden humidity through crawl-space vents and foundation gaps. Ductwork in that saturated environment wicks moisture through seams and porous insulation even when interior walls read dry. We pulled three sections of fiberglass-lined flex duct from a 1960s ranch on the flats near the Corte Madera Creek channel and found visible mold growth blooming on the interior liner, despite the homeowner reporting no leaks or water damage anywhere in the house. After camera inspection mapped the contamination, we set the system under negative pressure and ran agitation tools through every supply and return run, then HEPA-filtered the exhaust so spores never re-entered the living space. The homeowner’s musty odor complaint at two registers disappeared, and we flagged the crawl-space vapor issue that a fogging ‘sanitizer’ would have masked for a season at best. Call (469) 972-3151 if your registers smell musty.
No. Fogging wets the duct liner without removing source material, and in Corte Madera’s humid crawl spaces that residual moisture can feed new microbial growth within weeks. The EPA does not recommend biocide fogging as a routine duct treatment. We remove mold mechanically with brush agitation and negative-air extraction, then address the crawl-space moisture source that caused it. Call (469) 972-3151 for an inspection that shows you what’s actually inside your ducts.
Flats homes sit on bay-fill soil with chronically damp crawl spaces; hillside homes face wind exposure and different drainage patterns but generally drier subfloor conditions. We inspect for mold more aggressively on the flats and spend more time evaluating crawl-space vapor barriers. Hillside systems more often need attention to dust and debris from wind-borne particulate. The cleaning process is similar; the diagnostic emphasis changes. Call (469) 972-3151 and we’ll tailor the inspection to your neighborhood.
We clean the full mechanical system including blower motor, evaporator coil, return plenum, and filter rack when accessible. In Corte Madera, mold often establishes at the blower compartment where return air first enters the system. Cleaning only supplies and registers leaves that reservoir intact and allows rapid re-contamination. Our full-system approach is why we can offer the 365-Day Done Right Promise. Call (469) 972-3151 to schedule.
The EPA estimates indoor air can carry two to five times the concentration of certain pollutants as outdoor air, largely because modern homes recirculate the same volume through HVAC systems without adequate filtration or ventilation. For Corte Madera ranch homes on the flats, this means marsh-driven mold spores, dust mite debris, and volatile compounds from damp crawl spaces get trapped in the closed loop of forced-air heating and cooling. Your system becomes the delivery mechanism for contaminants you’ve never seen. We break that cycle with mechanical source removal, HEPA-contained extraction, and filtration upgrades sized to your actual airflow. Call (469) 972-3151 for a free estimate.
