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.
Air Duct Cleaning Company in Castro Valley, CA
Air duct cleaning in Castro Valley typically costs between $310 and $710 for a whole-home system, depending on home size and how long it’s been since the last cleaning. Most Castro Valley homes are 1950s-1970s ranch builds with crawl-space duct runs, and the valley’s bowl-shaped geography traps marine-layer moisture and oak pollen in ways that make ductwork here accumulate debris faster than in San Leandro or Hayward. We plan every Castro Valley job around those conditions before we ever walk through your door. Call (323) 918-4345 and we’ll explain what we’d do at your house, step by step, with a written price before anything starts.
Why Castro Valley Homes Are Different
Castro Valley sits in a literal bowl. The marine layer pushes in from the Bay each morning, settles into the valley, and holds relative humidity higher and longer than in the flatland East Bay communities just west of the hills. For the ranch homes that make up most of Castro Valley’s residential core, that means ductwork routed through unconditioned crawl spaces spends months of the year carrying damp, still air. Condensation forms inside those ducts, and conditions like that are exactly what mold and mildew need to get established.
On top of the moisture, the Diablo Range foothills that ring the community are covered in oak woodland and annual grasslands. In spring, those hillsides shed pollen straight down into the valley, especially along Cull Canyon and the Five Canyons corridors. Technicians working those neighborhoods consistently find the heaviest duct contamination closest to the hill margins, where evening down-slope winds push oak debris and grass particulates toward the shaded sides of ranch homes. Many of these homes are now 50 to 70 years old, with flex-duct liner that has degraded, joints that have worked loose, and debris packed into runs nobody has opened in years. That combination – aging ductwork, crawl-space exposure, trapped humidity, and heavy pollen loads – means a Castro Valley duct cleaning job often involves more disassembly and more careful inspection than the same job in Hayward or San Leandro.
Our Main Castro Valley Services
These are the two services Castro Valley homeowners call us about most often. Each has its own Castro Valley page with full pricing and job details.
Air Duct Cleaning in Castro Valley
Castro Valley’s crawl-space duct systems are the main reason this job takes patience and the right equipment. We access supply and return plenums, clean each trunk line and branch run, and remove the kind of packed organic debris that accumulates faster here than in more open nearby cities. Homes along the valley’s hill margins tend to show heaviest buildup in return-air ducts on shaded exterior walls. We use Rotobrush and Nikro equipment sized for residential systems, and we document the work with before-and-after photos of your actual ducts. See full details on our Air Duct Cleaning in Castro Valley page.

Dryer Vent Cleaning in Castro Valley
Lint fires in dryer vents are a real risk everywhere, but Castro Valley’s ranch homes often have longer vent runs that exit through crawl spaces or along exterior walls with multiple elbows. Each bend is a place where lint collects. We run a rotating brush the full length of the vent, confirm airflow at the termination point, and leave the laundry area clean. We use Guardsman vent brushes for tight runs and take a photo of the vent interior before we finish. Pricing and the full walkthrough are on our Dryer Vent Cleaning in Castro Valley page.

No. Air duct and dryer vent cleaning don’t require building permits in Castro Valley. If your home is in an HOA like those in Palomares Hills or Five Canyons, the work is entirely inside your home or existing vent runs, so no HOA approval is needed either. We handle the whole job without involving any third party.
In many cases, yes. The trapped marine-layer humidity and heavier pollen loads from the surrounding hills mean Castro Valley ducts can accumulate organic debris faster than homes in flatter, drier parts of the East Bay. Many Castro Valley homeowners find an every-3-to-5-year cleaning schedule works well, compared to the 5-to-7-year interval that’s common elsewhere. But every home is different, and we’ll tell you honestly after looking at yours – call (323) 918-4345 to schedule.

What Castro Valley Customers Say
"New house, old dusty ducts. They were gentle in the house, laid down drop cloths, and double checked every register was sealed back up. Air smells fresh now."
- Scott Hemmings"Friendly, calm crew that clearly cared about the house. Covered their shoes, protected the floors, and double checked they'd closed up every vent cover properly. Would have them back."
- Omar Zaid"Ducts and dryer vent both. They put runners down the whole hall and wore booties. Spotless after, and they showed me photos of what came out. Worth every penny."
