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 Alum Rock, CA
Air duct cleaning in Alum Rock runs $450 – $850 for a typical single-story home, with most jobs falling in the $550 – $700 range depending on system size and contamination level. We dispatch crews from our San Francisco Bay Area office to serve Alum Rock directly, and we schedule most work within 3 – 5 business days. The defining factor here is the housing stock: post-WWII ranch homes with original galvanized steel ductwork that has never been sealed or properly cleaned, sitting in attic spaces that hit 140°F through summer. Call us at (361) 326-5060 for a free written estimate.
Why Alum Rock Homes Are Different
Alum Rock sits at the foot of the Diablo Range, where summer temperatures regularly exceed 95°F and the dry, dusty hillsides send fine particulate matter into attic ducts through leaks. The housing stock is dominated by single-story ranch-style homes built in the 1950s and 1960s, most with original rigid metal ductwork that was never insulated or sealed to modern standards. After the first major heat wave in June, we see a predictable spike in calls from homes near Alum Rock Park, where ducts have pulled in dust from the exposed hillsides all spring.
Unlike neighboring Santa Clara or Milpitas, where newer construction uses flexible ducting and tighter building envelopes, Alum Rock’s older homes often have undersized returns and leaky joints that loosen further under thermal expansion. The combination of old rigid ducts and extreme attic temperatures frequently cracks flexible connectors at the air handler, meaning a cleaning job often reveals repair needs. Winter rains introduce another variable: moisture finds its way into neglected systems, and we’ve found mold growth in ducts that haven’t been opened in thirty years. Seismic activity over decades hasn’t helped, either. Joint separation is common in galvanized steel runs that were installed before modern duct-sealing standards existed.
Our Main Alum Rock Services
Most Alum Rock homeowners call us for one of three jobs. Each has its own dedicated page with full pricing, process details, and local considerations.
Air Duct Cleaning in Alum Rock
We clean the full supply and return network using a Rotobrush rotary brush system for the main trunk lines and branch ducts, followed by negative-air extraction with Nikro equipment to pull loosened debris out of the system. In Alum Rock, we often find construction debris from the 1950s original build still sitting in galvanized steel trunks, plus decades of accumulated hillside dust that entered through unsealed joints. We photograph the interior before and after so you see what came out. Air Duct Cleaning in Alum Rock covers full pricing and what to expect on appointment day.
Dryer Vent Cleaning in Alum Rock
Dryer vent cleaning in Alum Rock addresses a specific fire hazard that older homes compound: original vent runs were often routed through long horizontal paths to exterior walls, with multiple elbows that trap lint. The dry summer heat bakes accumulated lint into a hardened layer, and the 1950s-era wall caps many homes still have lack proper backdraft dampers. We clean the full run from dryer to termination, inspect the cap, and measure airflow before and after. Dryer Vent Cleaning in Alum Rock has full details and pricing.
Duct Sealing in Alum Rock
Duct sealing targets the root problem in most Alum Rock homes: leaky joints and disconnected runs that waste conditioned air and pull in attic dust. We apply mastic sealant to all accessible joints and use metal-backed tape at the air handler connection, then pressure-test the system to verify results. Many Alum Rock homes lose 20 – 30% of their conditioned air through duct leaks before it ever reaches the rooms. Duct Sealing in Alum Rock explains when sealing makes sense versus when full replacement is the better call.
