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 Alameda, CA
Air duct cleaning in Alameda typically costs $350 – $650 for a whole-home system and is scheduled by appointment with a written price confirmed before work begins. The marine layer and salt-laden bay air here create a unique maintenance challenge that mainland East Bay homes don’t face: corrosive salt deposits mixed with moisture-driven mildew inside ductwork. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we’ve built our process around Alameda’s coastal conditions. Call (361) 326-5060 for a free estimate.
Why Alameda Homes Are Different
Alameda’s geography as an island city in San Francisco Bay means every home breathes air saturated with salt and persistent humidity from the marine layer. Most of the housing stock predates 1960: bungalows and Victorians in the Gold Coast and Bronze Coast neighborhoods still run on original galvanized steel ducts that rust and pit from decades of salt exposure. We’ve opened systems in the East End where the interior metal looked like it had been sandblasted.
Newer waterfront condos along the Estuary and South Shore use sealed flex duct, which traps salt particles against the interior walls and requires different equipment. The persistent bay breezes keep relative humidity high enough that mold colonies establish quickly in poorly ventilated runs. On the Gold Coast specifically, we regularly see salt crystal buildup that appears as white powder coating the duct interior. After cleaning these systems, we apply a corrosion-inhibiting treatment to slow re-rusting. This isn’t standard practice inland; it’s specific to Alameda’s coastal chemistry.
Our Main Alameda Services
Most calls from Alameda homeowners fall into three categories: full system cleaning, dryer vent maintenance, and duct sealing for efficiency and air quality.
Air Duct Cleaning in Alameda
We clean the complete supply and return network using a Rotobrush rotary brush system for flex duct and negative-air methods for rigid galvanized lines. In Alameda’s pre-1960 homes, we pay particular attention to rust-weakened seams that can open under agitation. Every job gets a written price before we start, and we photograph the interior before and after so you see what came out. Air Duct Cleaning in Alameda covers our full process for island homes.
Dryer Vent Cleaning in Alameda
Dryer vents in Alameda’s older homes often run through walls with galvanized elbows that corrode internally, creating lint traps where fires start. We use Nikro equipment to extract packed lint and inspect the full run with a camera when access is limited. Salt corrosion can perforate vent walls in exterior runs facing the bay, and we flag these for replacement rather than cleaning. Dryer Vent Cleaning in Alameda has the details.
Duct Sealing in Alameda
Leaky ducts in Alameda’s humid salt air pull attic and crawl space moisture directly into the living space, accelerating mold growth and wasting conditioned air. We seal with mastic and mechanical fasteners, then pressure-test to verify the seal holds. In Victorians with balloon framing, we often find return leaks that have been drawing unfiltered bay air for decades. Duct Sealing in Alameda explains how we fix it.
