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 Kensington, CA
Air duct cleaning in Kensington, CA is a different job than it is in most Bay Area communities, because the homes here were largely built between the 1950s and 1970s, and many still carry original sheet-metal ductwork sealed with cloth duct tape that has dried, cracked, and opened at the joints over the decades. Those failing seals pull attic and crawl-space air into the living-space supply, which means fiberglass particles, rodent dander, and mold spores ride along with the air your family breathes. Kestrel Air Duct Cleaning handles Kensington jobs with written pricing before work begins and a 365-Day Done Right Promise in writing. Call (469) 972-3151 for a free estimate.
Why Kensington Homes Are Different
Kensington sits in the East Bay hills just north of Berkeley, where the marine layer rolls in most summer mornings and burns off by early afternoon. That daily moisture cycle, combined with cool, damp winters, means ducts in unconditioned crawl spaces and attics here see condensation far more often than homes in drier inland communities. What we regularly find in Kensington homes is this: original galvanized duct boots set directly against subfloor or foundation materials with no vapor barrier, which lets ground moisture wick into the lowest duct sections. The result is standing sediment and active mold at floor registers even when the main trunk looks relatively clean.
The housing stock compounds the issue. Kensington’s streets are lined with mid-century ranch, cape, and split-level homes built for Berkeley and San Francisco commuters. Those homes often still run bare sheet-metal duct runs, sometimes with fiberglass-lined flex sections added during later HVAC retrofits. Fiberglass liner degrades, sheds particles, and traps compacted debris in ways that newer flex duct doesn’t. When we open a register in the older neighborhoods around Colusa Circle or up toward the Kensington Community Center, we’re usually looking at decades of accumulated dust, pet hair, and construction debris that ordinary filter changes never touched.
None of this is a reason to panic. It just means duct cleaning in Kensington has to be done with negative-air extraction and brush agitation, not a shop vac and a hopeful look. Our technicians use Rotobrush rotary brush systems to dislodge debris at the duct wall and Nikro negative-pressure units to pull what’s loosened out of the house, while Abatement Technologies HEPA filtration keeps the particles from re-entering your living space during the work.
Our Main Kensington Services
Kensington homeowners call us most often about two things: dirty air ducts that are circulating decades of accumulated dust, and dryer vents that have packed with lint in the East Bay’s damp air. Here’s what each job involves in this community.
Air Duct Cleaning in Kensington
Air duct cleaning in Kensington means pulling the registers, agitating the duct walls with a Rotobrush rotary brush system, running Nikro negative-pressure extraction to pull loosened debris out, and sealing access points cleanly when the job is done. In Kensington specifically, we pay close attention to the floor registers in older ranch homes where duct boots sit directly on subfloor with no vapor barrier – that’s where we most often find hidden moisture damage. The full scope, including what pushes pricing up or down in this housing stock, is on the Air Duct Cleaning in Kensington page.
Dryer Vent Cleaning in Kensington
Dryer vents in Kensington homes run longer than average, often through crawl spaces or up through walls to roof exits, because the hillside lots and mid-century layouts put the laundry room far from an exterior wall. Those long runs give lint more surface to cling to, which means more frequent clogging than a short first-floor vent would see. We clean the full run from dryer to termination point, including the lint trap bypass that most homeowners never see. For details specific to Kensington homes, see Dryer Vent Cleaning in Kensington.

What pushes a Kensington job toward the higher end is the age of the home and the condition of the duct runs. Homes with original 1950s galvanized ducts, fiberglass-lined flex sections, or evidence of moisture at the floor registers take longer to clean properly than a newer system in good shape. Whatever the scope, our written price is in your hands before a single vent is touched, and it stays the same through the whole job.

What Kensington Customers Say
"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
- Preston Ngata"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
