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 Brentwood, CA
Air duct cleaning in Brentwood, CA typically costs $450 – $850 for a whole-home system and should include both supply and return trunk lines, branch ducts, and a post-cleaning camera inspection. Most Brentwood jobs take 3 – 5 hours because crews find more than dust: the clay soils here shift foundations and pull duct joints apart, so a proper cleaning usually reveals separations that need sealing before the system is closed back up. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we dispatch to Brentwood from our San Francisco Bay Area office. Call (361) 326-5060 for a free estimate with a written price before any work starts.
Why Brentwood Homes Are Different
Brentwood sits on expansive clay soils that shrink dramatically during the dry season when groundwater levels drop. That movement doesn’t just crack patio slabs; it shifts post-tension foundations enough to pull apart duct connections at plenums and boot joints. We’ve opened attic hatches in neighborhoods like Shadow Lakes and found supply boots completely detached from ceiling registers, blowing conditioned air into the insulation instead of the bedroom below.
The housing stock here is almost entirely 1990s-2020s tract construction: two-story stucco homes with flex-duct runs through attic spaces that hit 130°F+ in July and August. Those systems are now 15 – 25 years old, past the design life of flexible duct liner. The hot, dry Delta-influenced air pulls fine dust and agricultural soil particles straight into return grilles all summer, while the brief wet winters drive rodents into attic chases where they damage duct walls.
What this means practically: a crew that treats Brentwood like any other suburb will miss the structural problems. We inspect every joint with a borescope and carry mastic and mechanical fasteners to reconnect what’s come apart before we seal the system back up.
Our Main Brentwood Services
Most Brentwood homeowners call us for one of three jobs, each with its own local conditions and pricing. Click through for the specifics on your system.
Air Duct Cleaning in Brentwood
We clean the full system: supply and return trunk lines, branch ducts, registers, and grilles using a Rotobrush rotary brush system combined with negative-air containment from Nikro equipment. In Brentwood, we almost always find disconnected boots and plenum separations caused by foundation movement, so we quote sealing work alongside the cleaning when it’s needed. Every job gets a written price before we start and a post-cleaning camera walkthrough so you see what came out. Air Duct Cleaning in Brentwood
Dryer Vent Cleaning in Brentwood
Dryer vent blockages are a genuine fire hazard, and Brentwood’s long vent runs through two-story stucco walls compound the problem. We pull lint and debris with a rotary brush and high-velocity vacuum, then airflow-test the vent to confirm it’s moving at manufacturer spec. If the run is damaged or improperly routed, we note it in writing and quote repair separately. Dryer Vent Cleaning in Brentwood
Duct Sealing in Brentwood
Because of the soil-shift issue, duct sealing is often the most important part of a Brentwood service call. We reconnect separated joints with mechanical fasteners and seal with mastic rated for attic temperatures, then pressure-test the system to confirm leakage is below industry standard. This is where the 365-Day Done Right Promise matters: if a sealed joint fails within a year, we come back at no charge. Duct Sealing in Brentwood
