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 Kentfield, CA
Air duct cleaning in Kentfield costs between $390 and $790 for a full-system clean of a typical 2,000 to 2,500 square foot home, depending on how many returns, registers, and furnace units the house has. Kentfield jobs are shaped by the valley’s persistent damp: mid-century ranch and craftsman homes from the 1940s through 1960s, original sheet-metal ducts in perpetually humid crawl spaces, and bay laurel pollen coating return grilles every spring. Call (323) 918-4345 for an exact written quote before anything starts.
Why Kentfield Homes Are Different
Kentfield sits in a fog-collecting pocket below Mount Tamalpais and records some of the highest annual rainfall in the Bay Area – often 50 inches or more in a wet year. That moisture doesn’t just sit outside. It pushes into unconditioned crawl spaces and attics, keeping relative humidity higher here than in San Rafael or Corte Madera, even on clear July afternoons. When uninsulated sheet-metal ducts run through that damp, cool air, condensation forms inside the duct runs and stays there. Dust that would stay dry and powdery in a drier town becomes sticky, compacted, and far more likely to support mold and mildew growth. In Kentfield, duct cleaning is a moisture and biological-contamination problem first, and a dust problem second.
The housing stock compounds the issue. Most homes here were built in the 1940s through 1960s, with original ducts still in service. Those ducts run through crawl spaces shaded by dense bay laurel, oak, and redwood canopy, and we regularly find return-air grilles packed with redwood duff, decomposed leaf litter, and the fine, aromatic pollen that bay laurels release every spring. That pollen doesn’t just blow through – it coats the duct interior with a sticky film that binds other debris into layers that ordinary filters never touch. It’s also a meaningful allergen for a lot of Kentfield families. Homes in the wooded hillside neighborhoods above Sir Francis Drake Boulevard see this pattern most heavily.
Our Main Kentfield Services
These are the two services Kentfield homeowners call about most, each handled by background-checked, uniformed technicians working to the Cedarwell Care Promise.
Air Duct Cleaning in Kentfield
Kentfield’s older ductwork – much of it original sheet metal from the 1950s and 1960s – collects the same sticky bay laurel residue and moisture-bound dust year after year, and the valley’s humidity means what settles inside tends to stay damp long enough to become a biological concern, not just a nuisance. We clean the full run of supply and return ducts using Rotobrush and Nikro equipment, with shoe covers and drop cloths on every visit, a written price before any work starts, and a photo of the clean-up before the crew leaves. For the full breakdown of what’s included and what it costs here, see Air Duct Cleaning in Kentfield.
Dryer Vent Cleaning in Kentfield
Kentfield’s tight, wooded lots mean dryer vents often terminate into shaded alcoves or under overhanging tree canopy, where lint combines with decomposed leaf litter and redwood duff to pack exterior vent openings shut. A restricted dryer vent forces the dryer to run longer, and that’s a genuine fire risk – plus it leaves every load smelling musty in a town that’s already fighting damp air. We clean the full vent run from the dryer to the exterior cap, and because the ductwork in these older homes often has tighter clearances, we take extra care not to leave lint behind. Details are on our Dryer Vent Cleaning in Kentfield page.

Neighborhoods We Serve in Kentfield
We work throughout the Kentfield valley and the surrounding hillside streets, from the flatter lots near Sir Francis Drake Boulevard up into the wooded, bay-laurel-heavy neighborhoods where ductwork sees the most leaf litter and pollen. Homes closer to the creek and lower valley floor tend to have the most moisture-related buildup, while hillside homes usually need more attention to exterior vent debris. We schedule Kentfield jobs with enough time to do the work carefully, and we never rush a job to make it to the next one.

FAQs About Air Duct Cleaning Company in Kentfield
No. Air duct and dryer vent cleaning do not require a permit anywhere in Kentfield or unincorporated Marin County. The work is classified as routine home maintenance, not a structural or mechanical system change. If the job uncovers a duct that needs full replacement, that’s a different scope and we’ll walk you through exactly what applies before anything moves forward.
Most Kentfield jobs are scheduled within a few days, and we’re local to the area rather than driving in from another part of the Bay. Scheduling is coordinated from the brand’s San Francisco Bay Area office, with crews working Kentfield routes throughout the week. Call (323) 918-4345 and a live person will give you a straight answer on timing and a written price.
We do. Many Kentfield homes fall under HOA or neighborhood association rules, and while duct cleaning itself is interior work, we’re accustomed to scheduling around whatever access windows your association sets. For older homes with original ducts, we always check access points and clearances before quoting so the written price matches what the job actually involves.
