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.

AfterFast, Reliable Dryer Vent Cleaning Across Mill Valley
Dryer vent cleaning in Mill Valley typically runs $180 – $340 for a standard residential system, with most jobs completed in under two hours. Our crews dispatch from the San Francisco Bay Area office and carry the rotary brush systems, negative-air machines, and camera inspection gear needed for Mill Valley’s older hillside homes. Call (361) 326-5060 for a written estimate before any work starts.
We’ve worked through Tamalpais Valley, Almonte, and the Sycamore Park area enough to know the local patterns. Mill Valley’s canyon-floor geography means dryer vent runs on hillside homes often terminate below the deck line or into a shared chase, so lint and moisture can back up into the wall cavity rather than exhausting cleanly – a scenario that rarely occurs in the flatter, sunnier towns across the bay. That dampness, combined with original galvanized or early flex ductwork in homes built before 1960, creates fire and mold risks that demand more than a quick brush-and-go cleaning.
Why Hollis Air Duct Cleaning Is Mill Valley’s Preferred Dryer Vent Cleaning Company
Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004. Our Dryer Vent Cleaning in Mill Valley follows The Garrison Standard: arrive inside the quoted window, price in writing, complete the job by the book, and leave the site clean. Every technician is background-checked and uniformed, and our phones are answered by a live person 24 hours a day, 7 days a week – no voicemail loops.
Mill Valley homeowners call us back because we document what we find. In Tamalpais Valley, our tech responded to a homeowner who reported a burning smell during cycles. Using camera inspection and agitation tools, we found a severely clogged lint pathway in an older flex duct that ran through a cold, damp crawlspace – the perfect environment for mold growth. We performed source removal with negative pressure and HEPA filtration, then verified clear airflow with a blower motor amp draw test. The 365-Day Done Right Promise backed it in writing: if the work fails within a year, we return and make it right at no charge, including a free second visit.
Dryer Vent Inspection in Mill Valley
Dryer Vent Inspection in Mill Valley is where we start every job, because assumptions about vent condition here are often wrong. A typical inspection runs $120 – $180 and includes camera scoping of the full run, airflow measurement, and written documentation of what we find. In Mill Valley’s hillside homes, we regularly discover vents that appear clear from the outside but are packed with lint where the run dips through a damp crawlspace or makes a sharp turn behind a finished wall.
Camera Scoping and Airflow Testing
We feed a borescope through the entire vent path to locate blockages, separations, and moisture damage that a visual check from the exterior cap misses. Then we measure static pressure and blower motor amp draw to quantify how hard the dryer is working. Numbers don’t lie, and we write them down before quoting any repair or cleaning.
Written Condition Reports for Insurance
After water intrusion or wildfire smoke events, insurers want documentation. Our inspection reports include timestamped photos, airflow readings, and a clear statement of whether the vent can be cleaned or must be replaced. This matters in Mill Valley, where the 2020 Woodward Fire left layers of ash inside return ducts in the Sycamore Park and Cascade Canyon areas, and where winter condensation in canyon-floor crawlspaces can saturate flex duct beyond recovery.
Commercial Dryer Vent Cleaning in Mill Valley
Commercial Dryer Vent Cleaning in Mill Valley covers multi-unit buildings, laundromats, restaurants, and any business with high-velocity or continuous dryer use. Pricing typically starts at $280 for a straightforward two-story system and ranges to $600+ for multi-vent commercial setups with rooftop terminations or shared chases. We schedule around your operating hours and provide the same written price, same documentation, and same 365-Day Done Right Promise that our residential customers receive.
Multi-Unit and HOA Properties
Condo complexes in Mill Valley often share vent chases between units, meaning one clogged line can affect multiple dryers and create liability for the HOA. We map the full system, clean each branch with rotary agitation and negative-air containment, and test every termination point. The report goes to your property manager with photos and airflow verification.
Kitchen and Hospitality Exhaust
Restaurants near downtown Mill Valley or along Miller Avenue run dryers for linens and uniforms alongside grease-producing kitchen exhaust. We clean the dryer vent separately from the hood system, using different tools and protocols, and we document both for fire marshal inspection records.
Trusted Brands We Service in Mill Valley
Our Dryer Vent Cleaning crews carry professional-grade equipment from Rotobrush for rotary brush agitation, Nikro for negative-air containment and HEPA vacuuming, and filtration products from Abatement Technologies and Guardsman. We stock common vent caps, bird guards, and transition ducts for Mill Valley’s older housing stock, so most repairs don’t require a second trip. When we encounter a specialty part – like a rooftop termination for a hillside home in Cascade Canyon – we source it fast and communicate the timeline in writing.
Common Dryer Vent Cleaning Problems We See in Mill Valley Homes
- Condensation-saturated lint in canyon-floor crawlspaces. Mill Valley’s cool, damp winters create moisture inside vent runs that terminate below grade or through shared chases. Homeowners assume the vent is dry because the laundry room feels fine, but the crawlspace section is packed with moldy, compressed lint that a standard visual check misses entirely.
- Original flex duct crushed by decades of settling on hillside slopes. Many Mill Valley homes built before 1960 still have early aluminum flex duct that has sagged, kinked, or been compressed by rodent activity in the crawlspace. The dryer runs longer, gets hotter, and the homeowner blames the appliance instead of the vent path.
- Bird guards missing or improperly installed on rooftop terminations. Homes in Tamalpais Valley and Almonte with rooftop vent exits often have no protection against nesting birds or driven rain. We replace these with code-compliant guards that allow proper airflow while blocking entry.
- Ash and smoke particle infiltration after wildfire season. Fine particulate from Marin Headlands fires gets pulled into laundry areas through poorly sealed duct connections, then recirculates through the home when the HVAC runs. We check MERV ratings and filter condition during every dryer vent job to catch this crossover contamination.
Pricing for Dryer Vent Cleaning in Mill Valley, CA
A standard residential dryer vent cleaning in Mill Valley runs $180 – $280 for a single-story system with accessible termination. Homes with rooftop exits, multi-level hillside runs, or significant lint compaction typically fall in the $260 – $340 range. Commercial systems start at $280 and scale with vent count and access difficulty.
What moves the price: length of run, number of turns, whether camera inspection reveals damage requiring repair or replacement, and accessibility (crawlspace work costs more than ground-floor exterior access). We give you one flat price per system, agreed in writing, before any work starts. No per-vent pricing, no add-ons at the door. Estimates are free. Call (361) 326-5060 to schedule.

FAQs About Dryer Vent Cleaning in Mill Valley
Every 12 – 18 months for most Mill Valley homes, and every 6 – 12 months if your vent runs through a crawlspace or terminates below a deck where winter condensation accumulates. The damp microclimate in Tamalpais Valley and Almonte accelerates lint compaction and mold growth compared to drier inland areas. Call (361) 326-5060 to set up a schedule that matches your home’s vent path.
Yes, and these are common in Mill Valley. Rooftop terminations require ladder access and proper fall protection, which our crews carry. Tight chases between hillside units need camera inspection first to map the run and locate blockages. We document the full path and verify clear airflow before leaving. The price is set in writing before we start, regardless of access difficulty.
Clothes taking more than one cycle to dry, a burning smell during operation, visible mold on the exterior vent cap, or excessive humidity in the laundry room during winter months. In Mill Valley’s canyon-floor neighborhoods, also watch for musty odors from the crawlspace and lint debris collecting on exterior walls below the vent termination – both indicate moisture backup and poor exhaust flow.
Yes. We clean dryer vents for multi-unit residential buildings, laundromats, restaurants, and hospitality properties throughout Mill Valley. Commercial jobs receive the same written pricing, camera documentation, and 365-Day Done Right Promise as residential work. We schedule around your operating hours to minimize disruption.
Dryer vent cleaning targets the single exhaust path from your dryer to the outside, using rotary brushes and negative-air tools designed for lint removal and fire prevention. Standard air duct cleaning addresses the supply and return ductwork of your HVAC system, which requires different equipment and protocols. In Mill Valley, we often recommend Air Duct Cleaning - Mill Valley alongside dryer vent service because fine lint from a clogged dryer filter can bypass into HVAC returns and recirculate ash and smoke particles during fire season. We check your MERV rating and filter condition to assess whether combined service makes sense.
