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 Corte Madera, CA
Air duct cleaning in Corte Madera runs $450 – $850 for a typical single-system home, with most jobs completed in one visit. What drives the actual price is the condition of your ductwork, the age of your home, and whether we’re pulling decades of marine moisture and wildfire residue out of original galvanized steel. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we dispatch crews to Corte Madera from our San Francisco Bay Area office. Call (361) 326-5060 for a written estimate before any work starts.
Why Corte Madera Homes Are Different
Corte Madera sits in the Tamalpais Valley, where three forces hit duct systems harder than almost anywhere else in Marin. The marine layer rolls in thick off the bay, pushing humidity into crawl spaces and attics where galvanized steel ductwork corrodes slowly from the outside in. That same fog, combined with wet winters, creates conditions inside ducts where mold and mildew take hold without homeowners noticing until the smell reaches the vents.
Then there’s fire season. When wildfires burn in the surrounding Marin hills, Corte Madera homes with leaky duct connections pull smoke and ash directly into the system. After major fire events, we see a surge of calls from neighborhoods like Christmas Tree Hill and Chapman Park, where homeowners report smoky odors coming from vents even after the air outside has cleared. The older ranch homes in these areas, built in the 1950s and 1960s, often have original ductwork with gaps at the seams that act like intake valves for contaminated air.
The housing stock itself is a factor. Mid-century ranch construction means ducts run through unconditioned crawl spaces or attics, exposed to temperature swings and moisture. Galvanized steel was standard then, and after sixty-plus years it can flake internally, shedding rust particles into the airflow. We don’t see this combination of fog corrosion, fire infiltration, and aging metal in newer Marin communities with flex-duct systems.
Our Main Corte Madera Services
Most calls we get from Corte Madera fall into three categories. Each has its own page with detailed pricing, process, and local specifics.
Air Duct Cleaning in Corte Madera
We clean the full supply and return network using a Rotobrush rotary brush system for mechanical agitation, paired with Nikro negative-air machines that pull loosened debris out of the home entirely. In Corte Madera, this matters more than in drier climates because the brush action breaks up mold colonies that grow on the interior of humid duct walls, while negative-air containment keeps those spores from resettling in your living space. We also inspect for corrosion damage that could indicate it’s time to replace rather than clean. Air Duct Cleaning in Corte Madera covers full pricing and what to expect on the day.
Dryer Vent Cleaning in Corte Madera
Dryer vent blockages are a fire hazard, and in Corte Madera’s older homes the vent runs are often longer and more convoluted than code would allow today. We use rotary brushes and high-velocity air tools to clear lint buildup from the dryer connection through the exterior cap, checking for proper airflow with a calibrated meter. If your dryer takes two cycles to finish a load or the laundry room feels humid, the vent is likely restricted. Dryer Vent Cleaning in Corte Madera has full details on when to schedule and what it costs.
Duct Sealing in Corte Madera
Leaky ducts are the reason smoke and pollutants enter Corte Madera homes during wildfire season, and they’re also why heating and cooling bills run higher than they should. We seal accessible duct seams with mastic and reinforced mesh, then pressure-test the system to verify the seal. In neighborhoods like Christmas Tree Hill, where original ductwork has sixty years of thermal expansion and contraction at the joints, this can cut conditioned-air loss by 20 – 30 percent. Duct Sealing in Corte Madera explains the process and when sealing makes more sense than replacement.
