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.
Fast, Reliable Dryer Vent Cleaning Across San Anselmo
Dryer vent cleaning in San Anselmo typically runs $150-$280 for a standard single-family home, and most jobs are scheduled within a few business days. We’re Morton’s Air Duct Cleaning, and our crews work the Ross Valley regularly - from the Craftsman bungalows lining Sir Francis Drake Boulevard to the hillside homes above Red Hill Avenue. You can reach us at (323) 918-4345 for a free written estimate before anyone steps into your home.
San Anselmo’s older housing stock and damp valley climate create dryer vent problems you won’t find in drier inland towns. Our technicians know to check for moisture backflow in raised crawl spaces, especially in homes near San Anselmo Creek that saw flooding in 2005 and 2006. We bring Rotobrush and Nikro equipment built for tight access, and we work to the Cedarwell Care Promise - shoe covers, drop cloths, quiet tools during nap hours, and a photo of the clean-up before we leave.
Why Morton’s Air Duct Cleaning Is San Anselmo’s Preferred Dryer Vent Cleaning Company
We’ve been part of the Cedarwell family since 2005, and our San Francisco Bay Area office dispatches crews to San Anselmo homes throughout the week. That local coordination means we’re not driving from Sacramento or San Jose - we’re nearby, familiar with Marin County’s permit environment, and able to return quickly if something needs a second look.
Our San Anselmo customers tend to mention the same things in feedback: the written price held up, the crew asked about pets before starting, and the photo proof at the end showed a clean house, not just clean ducts. We don’t publish review counts or star ratings we can’t verify, but we do stand behind every job with the 365-Day Done Right Promise. If it’s not right, we make it right. No expiration date, no paperwork chase.
Background-checked, uniformed technicians arrive with professional-grade equipment - not rental shop vacs with a brush taped to the hose. For families with kids and pets in San Anselmo, that matters. We use pet-safe products where available, and we plan our tool noise around your household schedule when we can.
Dryer Vent Repair in San Anselmo
Dryer Vent Repair in San Anselmo often means fixing what decades of moisture and poor original installation have damaged. The town’s pre-WWII housing stock - Craftsman bungalows, Colonial Revivals, Victorian cottages - was built before modern dryer vent codes existed. Many original vent runs terminate low in raised crawl spaces, where Ross Valley fog can migrate backward through the lint pathway, or where 2005-2006 floodwater left corrosion and mold-seeded debris that a simple cleaning won’t address.
Our repair work starts with a camera inspection of the full run. We document what we find, show you the footage, and give you a written price before touching tools to the vent. Typical repair work in San Anselmo runs $180-$450 depending on rerouting length, material replacement, and crawl-space access difficulty.
Crushed Transitions and Rigid Run Damage
The flexible transition hose behind your dryer gets compressed every time the unit moves - for cleaning, for maintenance, for retrieving a lost sock. In San Anselmo’s older homes with tight utility closets, this happens constantly. We replace crushed transitions with proper metal semi-rigid ducting and secure it so it stays round and airflow stays strong.
Rerouting Above the Foundation Line
When we find a vent terminating inside a damp crawl space, we reroute to an exterior wall penetration above the foundation. This stops the backward migration of humid valley air and prevents lint accumulation in a space you can’t see. It’s more work than a surface clean. It’s also the only fix that lasts.
Dryer Vent Cleaning Company in San Anselmo
Dryer Vent Cleaning Company in San Anselmo means more than brushing out the lint trap and calling it done. At Morton’s, our Dryer Vent Cleaning service follows a full-source-removal protocol: camera inspection of the entire run, mechanical agitation with Rotobrush tools to dislodge adhered lint, negative-air extraction with Nikro equipment, airflow testing before and after, and documentation photos you can keep.
A standard cleaning for San Anselmo homes runs $150-$280. Homes with longer runs, multiple bends, or significant lint compaction from years of neglect fall toward the higher end. We tell you where you land before we start, and that price doesn’t change when we’re halfway through the job.
What “Source Removal” Actually Means
Source removal is the NADCA-standard approach: we remove the contamination from the duct, not just move it around. Fogging a “sanitiser” into a dirty vent is the opposite - it wets the lint, can drive mold deeper into porous materials, and leaves you paying for a smell instead of a fix. We don’t sell fogging upsells. If your vent needs antimicrobial treatment, we’ll show you the mold on camera first, and we’ll quote it as a separate line item with the product name and EPA registration.
Camera Documentation You Keep
Every San Anselmo job includes before-and-after footage of the full vent run. You’ll see the lint buildup, the blockage point, and the clear passage afterward. If we find flood-related mold in a low-lying section, you’ll see that too - and we’ll explain exactly what remediation it requires beyond standard cleaning.
Trusted Brands We Service in San Anselmo
Our crews carry professional equipment from Rotobrush, Nikro, and Guardsman - brands built for residential duct and vent work, not entry-level rental gear. Rotobrush’s flexible cable systems navigate the tight bends common in San Anselmo’s pre-1940s homes, while Nikro’s negative-air machines maintain proper containment during agitation. We stock common replacement parts - vent caps, transitions, rigid duct sections, bird guards - so most repairs finish same-visit without waiting for a parts run to San Rafael. For San Anselmo homeowners, that means one appointment, one crew, one written price, and one photo of the clean-up before we go.
Common Dryer Vent Cleaning Problems We See in San Anselmo Homes
- Low crawl-space terminations pulling backward fog. San Anselmo’s Ross Valley geography channels marine moisture deep inland, and vents that discharge into raised crawl spaces instead of through exterior walls allow that damp air to travel backward through the lint pathway. The vent “works” by basic airflow standards but quietly feeds moisture into the same foundation spaces that flooded in 2005-2006.
- Flood-seeded mold missed without camera inspection. Homes near San Anselmo Creek that took water in 2005 or 2006 may still harbor mold colonies in low-lying duct sections. Standard brushing cleans the lint but leaves the mold, which regrows on new lint within months. Camera inspection finds it. Fogging without source removal hides it.
- Tight crawl spaces limiting tool access. The original sheet-metal duct layouts under San Anselmo’s Craftsman bungalows weren’t designed for modern cleaning equipment. Short-cropped techs clean only the accessible segment and invoice for a “full” job. Our Rotobrush systems are built for low-clearance work, and we don’t bill complete until we’ve documented the full run.
- Crushed flex transitions behind the dryer. Every time the unit moves - and in San Anselmo’s compact utility spaces, it moves often - the transition hose compresses against the wall. Airflow drops. Drying times stretch. Energy bills climb. We replace with semi-rigid metal and secure it properly.

FAQs About Dryer Vent Cleaning in San Anselmo
Yes. If your crawl space took creek water and the ductwork was never sanitized afterward, mold likely seeded the low-lying sections of your dryer vent run. Standard lint removal won’t kill established mold colonies, and fogging without source removal just wets the problem. We camera-inspect first; if we find flood-related mold, we quote antimicrobial treatment as a separate, documented line item after the cleaning removes the lint substrate. Call (323) 918-4345 and mention the flood history when you book - our techs will bring the right equipment.
The Ross Valley funnels Pacific fog and marine moisture deep inland, and San Anselmo sits at the narrowest point of that funnel. Morning fog stagnates here, especially in winter, keeping ambient humidity higher than in drier Novato or sun-exposed Sausalito. When your vent terminates in a crawl space or has even minor airflow restriction, that humidity lingers inside the metal duct. Lint absorbs it. Mold spores germinate. Drying times creep upward long before you notice a problem.
Look at where the rigid duct exits your home. If it terminates with a hood on an exterior wall above the foundation line, it’s properly installed. If it disappears downward into the crawl space with no visible exterior hood, or if you see only a vague grille near ground level, it’s likely discharging into the foundation space - a common original installation in pre-1940s San Anselmo homes, and one that violates modern code. Our camera inspection shows the exact termination point and documents it for your records.
Vacuuming the lint trap and the area behind your dryer removes surface accumulation. It does not touch the 15-25 feet of duct running through your walls or crawl space, where the fire hazard actually lives. Our full-source-removal service camera-inspects the complete run, mechanically agitates adhered lint with Rotobrush tools, extracts it with Nikro negative-air equipment, and tests airflow at the exterior hood before and after. The lint trap is maybe 5% of the system. We clean the other 95%.
Absolutely. The low-clearance crawl spaces under Craftsman and Colonial Revival homes on streets like Oak Springs Drive or Madera Avenue weren’t built for modern equipment. Some duct runs require us to remove small sections of rigid pipe to gain access, then reassemble with proper sealing. Techs who aren’t prepared for this - or who don’t carry the right fittings - often clean only the accessible portion and invoice for a complete job. We document the full run on camera so you know what was actually reached.
