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.

Call (469) 972-3151 for a free estimate with no obligation.
We’ve learned San Rafael’s housing stock inside out. The postwar ranches in Lucas Valley with their original under-house vent terminations. The fourplexes and sixplexes in the Canal district with shared vertical exhaust stacks that nobody thinks to clean until the second-floor dryer starts failing. The hillside homes near Montecito where tight side yards force creative equipment setups. Each configuration demands a different approach, and showing up with a one-size-fits-all method leaves lint behind. That’s why our technicians carry Rotobrush rotary systems for agitation, Nikro negative-pressure units for source extraction, and Abatement Technologies HEPA filtration to keep whatever we loosen out of your living space.
Why Kestrel Air Duct Cleaning Is San Rafael’s Preferred Dryer Vent Cleaning Company
We’ve built our reputation in Marin County on one straightforward standard: the Kingswell Guarantee. Founded in 2004, our company puts a written price in your hands before touching a single vent, arrives inside the window we promised, leaves the job site cleaner than we found it, and backs the work with a 365-Day Done Right Promise in writing. If something fails within that year, we return and make it right at no charge. No courtesy calls, no discretion, no “we’ll see what we can do.” It’s documented on every invoice.
San Rafael homeowners call us back because we answer the phone with a live person, 24/7. Not a queue. Not a callback tomorrow. A real conversation about your dryer taking three cycles, your shared stack backing up into the unit above you, or that burning smell you noticed last Tuesday. Our technicians are background-checked, uniformed, and trained on The Kingswell Way: say the price, show up in the window, clean the site, put the guarantee in writing, come back if it fails.
We know the local patterns. The fiberglass-lined ductwork in Terra Linda that debonded after the 2017 North Bay fires and still traps particulate. The marine moisture near the Canal that colonizes mold inside flex duct. The parking restrictions on narrow streets that force longer hose runs and demand more powerful extraction equipment to compensate. This isn’t generic suburbia. It’s San Rafael, and the work reflects that.
Dryer Vent Installation in San Rafael
Dryer Vent Installation in San Rafael addresses a specific set of local problems: original 1960s vents that terminate into crawlspaces instead of outside, shared multifamily stacks that need individual unit isolation, and reroutes required by modern appliance upgrades that the existing ductwork can’t support. A typical installation or reroute in San Rafael runs $350-$650 depending on material length, access difficulty, and whether we’re cutting new exterior termination points through stucco, wood siding, or foundation vents.
Under-House Termination Corrections
In Terra Linda and Lucas Valley, we regularly find dryer vents that dump lint directly into crawlspaces or under raised foundations. This was standard construction in the 1960s. It violates current safety expectations and creates sustained moisture and mold risk. We reroute these through the nearest exterior wall with proper metal ducting, sealed joints, and a weatherproof cap.
Shared Stack Isolation for Multifamily Units
Canal district buildings with common vertical stacks often need individual unit isolation so one tenant’s lint doesn’t obstruct the pathway for everyone above. We install independent exhaust runs where structure allows, or fit code-compliant backdraft dampers and cleanout ports where shared stacks must remain.
Dryer Vent Repair in San Rafael
Dryer Vent Repair in San Rafael fixes the damage that accumulated lint, moisture, and age inflict on ductwork: disconnected joints behind walls, corroded sheet metal in crawlspaces, crushed flex duct from years of contact with framing, and failed termination caps that let birds and rodents enter. Most repairs in San Rafael fall between $200-$425, with camera inspection included to locate the exact failure point without unnecessary wall or ceiling openings.
Fire-Damaged and Smoke-Contaminated Duct
After major fire seasons, we find dryer vent walls coated with sticky smoke particulate that captures lint more aggressively than clean metal. Standard cleaning won’t remove this bonded layer. We use rotary brush agitation at higher contact pressure, followed by negative-air extraction, to restore the smooth interior surface that lets lint pass through.
Structural Access Repairs
San Rafael’s hillside homes and dense Canal district buildings often bury vent sections inside finished walls or under inaccessible crawlspaces. We scope first, repair only what’s necessary, and minimize disruption. When access is genuinely impossible from inside, we coordinate with our Bay Area office for roof or exterior wall entry points.
Trusted Brands We Service in San Rafael
Our technicians arrive with Rotobrush rotary brush systems to physically dislodge lint from duct walls, Nikro negative-pressure units to pull loosened debris out rather than pushing it deeper, and Abatement Technologies HEPA filtration to capture particles before they re-enter your home. For homeowners who want to maintain cleaner air between service visits, we stock Honeywell and Aprilaire filtration products with local parts availability for fast turnaround. These aren’t box-store shop vacs with brush attachments. They’re purpose-built tools that make the difference between a vent that looks clean and a vent that actually moves air.
Common Dryer Vent Cleaning Problems We See in San Rafael Homes
- Shared vertical stacks in Canal district multifamilies. Individual unit cleanings ignore the common riser, where years of accumulated lint from multiple dryers creates a fire risk for every connected unit. We clean the full stack from roof access or exterior termination, not just the branch line.
- Original under-house terminations in Terra Linda ranches. These 1960s vents dump lint into crawlspaces where it accumulates invisibly, attracts moisture, and supports mold growth. Homeowners often don’t know the problem exists until we camera-inspect.
- Collapsed fiberglass duct liner in Lucas Valley. The original liner debonds from the outer sheet metal shell, creating gaps that trap lint and smoke particulate while restricting airflow to a fraction of design capacity. Cleaning alone won’t fix this; we flag it for repair or replacement.
- Moisture-driven mold in bay-facing flex duct. San Rafael’s Canal flatlands draw consistent marine moisture that promotes mold colonization inside flexible dryer duct and at poorly sealed register boots. We find this even in buildings with no visible water intrusion.
Pricing for Dryer Vent Cleaning in San Rafael, CA
Most San Rafael dryer vent cleanings run $150-$275 for a standard single-family home with accessible exterior termination. Multifamily shared-stack cleanings range $225-$400 depending on building height, roof access requirements, and number of connected units. Dryer vent repair typically falls between $200-$425. Installation or reroute work runs $350-$650.
What moves the price: length and material of duct run (rigid metal vs. flex vs. fiberglass-lined), access difficulty (crawlspace, attic, roof), whether camera inspection reveals damage requiring repair, and whether we’re cleaning a shared stack serving multiple units. We give one flat price per system, agreed in writing before work starts. No per-vent pricing. No add-ons at the door. You’ll see before-and-after photos of your own ductwork, and the 365-Day Done Right Promise covers every job.

FAQs About Dryer Vent Cleaning in San Rafael
Call us at (469) 972-3151 and describe your building type; we’ll coordinate with your property manager or HOA to access roof terminations, common mechanical rooms, or exterior cleanout ports, and we schedule during windows that respect tenant occupancy. Most Canal district multifamily cleanings take 2-3 hours and require roof or exterior access rather than individual unit entry.
Your original 1960s vent likely terminates under the house or into a crawlspace rather than outside, trapping lint invisibly, and the fiberglass duct liner may have debonded to create particulate-trapping gaps that newer smooth-metal systems don’t have. Camera inspection reveals which specific condition is affecting your home.
Cleaning removes smoke particulate that bonds to lint accumulation and recirculates when the dryer runs, but it won’t address smoke infiltration through windows, doors, or HVAC intake systems; we often recommend pairing dryer vent service with full air duct evaluation if smoke odor persists throughout the house. Call (469) 972-3151 and we’ll assess whether your issue is vent-contained or whole-system.
Shared vertical stacks that have never been cleaned from the common riser, only per-unit, leaving years of compacted lint that obstructs airflow for every connected dryer and creates a concentrated fire risk in the building’s core. We were called to a 1960s Canal district fourplex where the downstairs tenant reported the dryer taking two cycles to dry a load. Using camera inspection from a roof access point, we found the shared vertical stack nearly 70% blocked with compacted lint and debris from years of use by three units. We set up negative pressure at the exterior termination, used agitation tools to break up the blockage, and pulled the material through HEPA filtration before confirming clear airflow for all connected dryers.
Yes, camera inspection is standard on every San Rafael job where access allows; it lets us show you the exact condition of your ductwork, locate blockages or damage without destructive exploration, and document before-and-after results. The inspection is included in your written price, not added separately.
