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 Strawberry, CA
Air duct cleaning in Strawberry, CA typically costs $350 – $650 for a whole-home system and is scheduled by appointment with a written price locked in before work begins. We’re Hollis Air Duct Cleaning, and the homes here on the Tiburon Peninsula present a specific set of problems you won’t find in inland Marin County. Most of Strawberry’s housing stock dates to the 1950s – 1970s, with ducts routed through uninsulated crawlspaces and exterior wall chases that pull in salt aerosol, redwood pollen, and crawlspace dust every time the system cycles. Call us at (361) 326-5060 for a free estimate with upfront pricing.
Why Strawberry Homes Are Different
Strawberry sits on the Tiburon Peninsula where the marine layer lingers longer than it does across the Richmond-San Rafael Bridge. That humidity, combined with salt-laden onshore air from San Francisco Bay, settles into crawlspaces and finds its way into ductwork through joints that were never designed for modern filtration.
The predominant housing here is mid-century ranch and split-level construction with low-pitch roofs and underfloor crawlspaces. Original ducts are sheet-metal or early flex duct with minimal sealing, and many homes still run unlined wall-cavity returns that openly connect to the attic and crawlspace. On the east side along the Tiburon Boulevard corridor, we regularly find 1960s foil-tape joints dried brittle from decades of marine-layer exposure. When we run a Rotobrush rotary system or Nikro negative-air machine through those old runs, the tape can unseal and cause a sudden pressure drop you’ll hear from the living room.
Most of our Strawberry calls come in late September, when homeowners fire up the furnace for the first time and smell musty, salty attic air pushed through duct runs that have been breathing crawlspace all summer.
Our Main Strawberry Services
Strawberry homeowners call us most often for these three jobs, each with its own page and local details.
Air Duct Cleaning in Strawberry
We clean the full supply and return network with a Rotobrush rotary brush system or Nikro negative-air machine, depending on duct age and condition. In Strawberry, we pay particular attention to wall-cavity returns that pull crawlspace air directly into the living space. The job includes vent covers, trunk lines, and accessible plenums. We photograph the before condition and show you the after. Air Duct Cleaning in Strawberry
Dryer Vent Cleaning in Strawberry
Dryer vents in Strawberry’s older homes often run through uninsulated exterior walls or long horizontal routes under the house, where marine humidity can accelerate lint compaction. We pull the full lint column with a high-velocity skipper and inspect the termination for proper backdraft damper function. A blocked dryer vent is a genuine fire hazard, and we treat it as such.

Duct Sealing in Strawberry
Strawberry’s original sheet-metal and flex duct systems lose conditioned air through joints that were never sealed to modern standards. We apply duct sealing mastic and mechanical fasteners to accessible joints, then pressure-test the improvement. For homes with chronic crawlspace odor or uneven heating between rooms, this often matters more than cleaning alone. Duct Sealing in Strawberry
