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.

Air duct cleaning in Lucas Valley-Marinwood typically runs $350 – $750 for a full residential system, with most jobs scheduled within a few days and completed in three to five hours. Our crews know the valley’s fog-damp winters and dry summers, and we’ve worked on enough mid-century homes here to spot the difference between a straightforward cleaning and a system that needs more attention.

Dispatch and scheduling for Lucas Valley-Marinwood are coordinated from our San Francisco Bay Area office, but the technicians who arrive at your door live and work in this region. They know the winding roads off Lucas Valley Road, the difference between the original Marinwood tract homes and the later builds up toward Big Rock, and why a house on the valley floor can have different duct issues than one perched on the hillside. That local familiarity saves time on every job.
Why Hollis Air Duct Cleaning Is Lucas Valley-Marinwood’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and our reputation in Marin County has been built one scheduled window, one written price, one clean site at a time. Lucas Valley-Marinwood homeowners tend to research thoroughly before inviting a crew into their homes, and they remember who showed up uniformed, explained the work, and left no mess behind.
Our response time to Lucas Valley-Marinwood is typically two to four days for standard scheduling, with live phone answering around the clock so you’re never stuck in a callback queue. Technicians arrive inside the quoted window, background-checked and in Hollis uniforms, with The Garrison Standard governing every interaction on your property.
What sets us apart here is our experience with the area’s unusual housing stock. Most Lucas Valley-Marinwood homes were built in the 1960s and 1970s with radiant floor heating and minimal or no original ductwork. When we get a call for Air Duct Cleaning, we often find ourselves evaluating whether the existing ducts can be cleaned effectively or whether the homeowner needs Duct Sealing in Lucas Valley-Marinwood or even partial retrofitting. That honesty, backed by our 365-Day Done Right Promise, is why Lucas Valley-Marinwood residents call us back and refer their neighbors.
Ductwork Cleaning in Lucas Valley-Marinwood
Ductwork Cleaning in Lucas Valley-Marinwood starts with understanding what kind of system, if any, is actually in your home. Many houses here, especially in the Marinwood tract off Lucas Valley Road, were built with radiant heat and either no ducts or small add-on systems installed decades later. Our first step is always a visual assessment to determine whether your ductwork is accessible, intact, and worth cleaning, or whether you’re facing a replacement situation.
A typical residential ductwork cleaning in Lucas Valley-Marinwood runs $350 – $550 for a standard system with 8 – 12 vents. Homes with add-on ductwork routed through uninsulated attics or crawlspaces, common in this area, may need additional attention and can run $500 – $750. We use Rotobrush rotary brush systems and Nikro negative-air machines to dislodge and extract debris without pushing it into your living space.
When Cleaning Makes Sense
If your ducts are intact, sealed, and simply loaded with dust from Lucas Valley-Marinwood’s dry summers, cleaning restores airflow and reduces the particulates cycling through your home. We see this most often in homes where a previous owner added forced-air cooling or heating to the original radiant system.
When We Recommend Replacement Instead
Original 1960s duct runs in uninsulated attics often degrade past the point where cleaning helps. If our inspection reveals collapsed sections, rodent damage, or disintegrating fiberglass liner, we’ll show you the video and explain why replacement or sealing is the smarter investment.
Air Duct Inspection in Lucas Valley-Marinwood
Air Duct Inspection in Lucas Valley-Marinwood is often the most valuable service we provide, because so many homes here have hidden or unconventional duct configurations that owners don’t fully understand. Our inspection uses a video borescope to show you exactly what’s inside your ducts, where they run, and what condition they’re in. An inspection alone costs $150 – $250, but we apply that fee toward your cleaning if you proceed with the work.
We recommend an inspection if you’ve just purchased a mid-century home in Lucas Valley-Marinwood and aren’t sure whether the ductwork is original, added later, or even present. The inspection also makes sense if you’re experiencing uneven heating or cooling, musty odors, or unexplained dust accumulation, all common complaints in this valley’s climate.
What the Camera Reveals
Our video inspection shows debris buildup, moisture staining, disconnected joints, and structural damage in real time. In Lucas Valley-Marinwood, we frequently find condensation-related mold in poorly ventilated crawlspace ducts during winter months, when fog rolls in and temperatures stay cool for weeks.
Written Documentation for Your Records
After every inspection, you receive a written summary with still images from the video. This becomes useful documentation for insurance claims, home sales, or simply tracking your system’s condition over time. No surprises, no verbal-only assessments.
Trusted Brands We Service in Lucas Valley-Marinwood
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for controlled debris extraction, and filtration upgrades from Aprilaire and Guardsman. We stock common replacement parts and media locally, so Lucas Valley-Marinwood homeowners aren’t waiting on shipping for standard maintenance items. When your system needs a filter upgrade or a sealing job with mastic and reinforced tape, we have the materials on the truck and the training to install them correctly the first time.
Common Air Duct Cleaning Problems We See in Lucas Valley-Marinwood Homes
- Nonexistent or add-on ductwork. Many Lucas Valley-Marinwood homes were built with radiant floor heating and only later received forced-air additions. These retrofit ducts are often undersized, poorly routed, and accumulate debris faster than systems designed from the ground up.
- Fog-season moisture and mold. The valley’s cool, damp winters create condensation in uninsulated attic and crawlspace ducts. We find mold and mildew in these runs every winter, especially in homes near the valley floor where fog lingers longest.
- Dust loading from dry summers. When the marine layer retreats and warm, dry weather sets in, Lucas Valley-Marinwood’s hillsides and exposed soils contribute to fine dust that gets pulled into any available intake. By September, we’ve seen ducts packed with a summer’s accumulation.
- Degraded original materials. Homes in the original Marinwood tract often contain ductwork from the 1960s with fiberglass liners that have begun to break down. Cleaning these systems without damaging them further requires lower-pressure methods and careful technique.
