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.

Why Hollis Air Duct Cleaning Is Los Altos’s Preferred Dryer Vent Cleaning Company
We’ve been working in Los Altos long enough to know what a 1962 ranch-style home off El Monte Avenue hides behind its walls. Roy Castellanos and our team have built our reputation here on showing up inside the window, pricing in writing, and leaving the site clean. Our Dryer Vent Cleaning crews are background-checked and uniformed, and our phones are answered by a live person 24 hours a day.
Los Altos homeowners don’t call us for the lowest teaser price. They call because the last outfit gave a $99 quote over the phone and billed $600 at the door. We don’t do that. The price is written down before we touch your dryer, and it doesn’t move. If the work fails within a year, we come back and make it right at no charge, including a free second visit. That’s The Garrison Standard, and it’s how we operate in every Los Altos home we enter.
Dryer Vent Inspection in Los Altos
Dryer Vent Inspection in Los Altos is often the most important service we perform, because the actual vent pathway in these mid-century homes rarely matches what you’d expect from the laundry room wall. Our technicians use camera-equipped tools to trace the lint path through original 1950s-60s wall cavities and crawlspaces that later permitted additions walled over, so the lint pathway often runs through unconditioned space that no other city’s stock would create. That makes camera inspection mandatory rather than optional in a large share of Loyola Corners and Old Los Altos homes. A typical inspection runs $150 – $250; if we proceed with cleaning, that inspection fee is applied toward the full service.
When You Need an Inspection First
Call for an inspection before cleaning if your dryer has always worked poorly in this home, if you’ve recently completed an addition or remodel, or if the exterior damper barely opens when the dryer runs. These are signs the vent run itself is compromised, and blowing air through a crushed or misrouted line won’t fix the underlying problem.
What the Camera Reveals
Our camera shows crushed transitions behind the dryer, sagging flexible duct creating lint traps at low points, and terminations that dead-end into attic or crawlspace voids rather than outdoors. In Los Altos, we find these conditions in roughly half the homes built before 1980 that haven’t had prior professional service.
Commercial Dryer Vent Cleaning in Los Altos
Commercial Dryer Vent Cleaning in Los Altos covers multi-unit buildings, homeowner association laundry facilities, and small commercial operations along San Antonio Road and downtown corridors where accumulated lint creates genuine fire risk at scale. These systems run harder and longer than residential units, with longer duct runs and more complex termination points. Pricing for commercial jobs starts around $350 and scales with the number of units, duct length, and access difficulty. We always inspect first and provide a written quote before work begins.
Multi-Unit Scheduling
We coordinate with property managers to service multiple units in a single visit, minimizing disruption to residents. Our Rotobrush agitation tools and Nikro negative-air machines handle the heavier lint loads commercial systems accumulate, and we document before-and-after conditions for your records.
Code Compliance Documentation
Los Altos enforces California’s commercial dryer vent requirements strictly. We provide written documentation of duct condition, cleaning date, and any repairs recommended to maintain compliance with local fire safety inspections.
Trusted Brands We Service in Los Altos
We stock parts and service dryers from every major manufacturer, and our equipment roster includes Rotobrush rotary brush systems for agitation cleaning and Guardsman filtration products to protect your home’s air during the process. For Los Altos homes with integrated HVAC concerns, we carry Aprilaire and Abatement Technologies filtration upgrades. Most replacement caps, transitions, and rigid metal ducting are on our trucks, so we don’t leave to chase parts while your laundry room sits open. If your vent termination needs replacement or you’re upgrading to a bird-guard cap, we handle it in the same visit.
Common Dryer Vent Cleaning Problems We See in Los Altos Homes
- Legacy foil runs extended through crawlspaces during remodels. A 1970s flexible duct stretched 24 feet across a crawlspace with multiple 90-degree turns will sag at every low point, creating lint traps that standard cleaning can’t fully clear without camera guidance and agitation tools.
- Walled-over terminations and crushed transitions. When a permitted addition enclosed the original vent path, the termination may now open into a wall cavity rather than outside, or the transition behind the dryer gets crushed during installation. Lint accumulates in the cavity and never reaches the exterior damper.
- Vents terminated into attic or crawlspace voids. We’ve found dryer vents dumping warm, moist air directly into unconditioned spaces, where lint coats rafters and creates both fire risk and moisture damage. This is especially common in homes where a previous owner rerouted the vent during a DIY remodel without pulling permits.
- Undersized or shared vent runs in additions. A new bedroom wing tied into the original trunk line without resizing the duct often leaves the dryer struggling against excessive static pressure. The symptom is long dry times; the cause is a design flaw that cleaning alone won’t correct.
Pricing for Dryer Vent Cleaning in Los Altos, CA
A standard residential dryer vent cleaning in Los Altos runs $180 – $280 for a straightforward single-story run with accessible termination. Jobs requiring camera inspection, crawlspace access, or duct rerouting typically fall in the $250 – $340 range. Commercial and multi-unit pricing starts at $350 and is quoted per system after inspection.
What moves the price: length of the vent run, number of turns, accessibility (crawlspace vs. direct exterior wall), condition of existing materials, and whether we find code violations that need correction. We do not charge per vent or hit you with add-ons at the door. The price is written down before we start, and that’s what you pay. Call (361) 326-5060 for a free estimate, we’ll inspect your system and give you an exact number.

FAQs About Dryer Vent Cleaning in Los Altos
Lint accumulation reduces airflow over time, but in Los Altos the more common culprit is a vent run compromised by a past remodel. A crushed transition, added 90-degree turn, or partial blockage in a crawlspace extension will slowly strangle performance until the dryer can’t expel moisture efficiently. Call (361) 326-5060 and we’ll camera-inspect the full run to find the actual restriction.
California building code requires dryer vents to terminate independently to the exterior, not be extended indefinitely or tied into existing runs. If your addition relocated the laundry room or extended the original vent path beyond 25 feet or four turns, it likely needs rerouting to meet code and function properly. We assess this during inspection and quote rerouting separately if needed.
Because Los Altos homes frequently have vent paths routed through walled-over crawlspaces and original 1950s-60s cavities, our inspections here rely heavily on camera tracing to map the actual duct geometry before we commit to cleaning. In markets with newer, simpler vent runs, inspection is often optional. Here, it’s standard practice for pre-1980 homes.
Yes. We clean commercial and multi-unit systems along San Antonio Road and in downtown Los Altos properties, with scheduling designed to minimize tenant disruption. Commercial jobs require inspection first; call (361) 326-5060 to arrange a site visit and written quote.
No. Dryer vent cleaning and HVAC duct cleaning are separate systems with separate access points, though we perform both. If your 1960s home has the original galvanized trunk lines with flexible duct additions, we can inspect the HVAC system during the same visit and quote air duct cleaning separately. The two services use different equipment and are priced independently.
At a ranch-style home off University Avenue near Loyola Corners, our tech pulled the dryer and found the flex transition crushed behind the unit and a 1970s foil run that a past remodel had extended 24 feet across the crawlspace with three 90-degree turns. Camera inspection showed heavy lint packing at the second bend; we ran agitation tools on a Rotobrush through the lint pathway and rebuilt the run with rigid metal to restore proper static pressure and airflow. That’s the kind of hidden problem we find regularly in Los Altos, and it’s why we don’t quote over the phone without seeing the system.
