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 Cotati
Dryer vent cleaning in Cotati typically runs $149 – $289 for a standard single-family home, and most jobs are scheduled within a few business days. We dispatch from our San Francisco Bay Area office, so crews are already rolling through Sonoma County when your appointment comes up.
We’ve worked the full spread of Cotati housing: the tight crawlspaces under downtown’s 1920s cottages near La Plaza Park, the flex-duct runs in Rancho Cotate’s 1990s tracts off Southwest Boulevard, and the split-levels tucked into the west-side subdivisions past E. Cotati Avenue. That daily fog-and-heat cycle here, cool and damp until noon then dry and hot by three, packs lint with coastal moisture that hardens into dense mats you don’t see inland. Our Dryer Vent Cleaning crews know to show up early when the old downtown metal ducts are still dry, and to hit Rancho Cotate’s plastic flex lines mid-morning when the sun has softened them just enough to work without tearing. Call (361) 326-5060 and we’ll put you on the schedule.
Why Hollis Air Duct Cleaning Is Cotati’s Preferred Dryer Vent Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and the Cotati market is one we know block by block. Homeowners here aren’t looking for the cheapest coupon; they’re looking for a crew that shows up in the window, prices the job before touching anything, and doesn’t invent add-ons once the van is in the driveway. That’s The Garrison Standard, and it’s how we operate every time.
Our technicians are background-checked and uniformed, and the price is written down before any work starts. No estimates that balloon at the door. The 365-Day Done Right Promise covers every dryer vent cleaning in Cotati: if the work fails within a year, we come back and make it right at no charge, including a free second visit. Phones are answered by a live person 24 hours a day, 7 days a week, no voicemail loops.
We also handle Duct Sealing in Cotati and Air Duct Cleaning in Cotati for homeowners who want the full system addressed in one visit.
Dryer Vent Cleaning Company in Cotati
Dryer Vent Cleaning Company work in Cotati means pulling built-up lint and debris from the full vent run, from the back of your dryer to the exterior cap, using rotary brush systems and high-velocity air tools that match the duct material. A typical cleaning in Cotati runs $149 – $289 depending on vent length, number of turns, and whether the run is rigid metal or flex duct. Most Rancho Cotate homes built in the 1990s have 15 – 25 foot flex runs with multiple elbows that take longer to clean properly; downtown’s older cottages often have shorter, straighter metal lines that move faster.
You’ll know it’s time when loads take more than one cycle, the outside vent flap barely opens during drying, or you smell burning lint. In Cotati’s climate, the coastal fog belt’s moisture binds lint into dense sheets that reduce airflow faster than dry inland dust.
What the Cleaning Covers
We clean the full vent path, not just the visible section behind the dryer. That includes the transition duct, the in-wall run, and the exterior termination point. For Rancho Cotate’s flex-duct systems, we use Rotobrush rotary tools with soft bristle heads that flex with the duct without tearing the thin plastic. For downtown’s original metal ducts, we switch to stiffer rotary brushes and Nikro negative-air machines that pull loosened debris backward so nothing settles in the line.
Scheduling Around Cotati’s Conditions
We plan Rancho Cotate flex-duct jobs on hot August mornings when the plastic is most workable, and downtown crawlspace work early before afternoon fog wets the dirt and metal. It’s the kind of local scheduling knowledge that comes from doing the work here regularly, not from a dispatch script.
Dryer Vent Inspection in Cotati
Dryer Vent Inspection in Cotati starts with airflow measurement at the exterior cap, visual examination of the full run with a borescope camera, and a written report on what we find. A standalone inspection runs $89 – $129; if you proceed with cleaning, we apply the inspection fee toward the full service. We recommend an inspection for any Cotati home where the dryer location has changed, where a new roof or siding job may have disturbed the exterior cap, or where you’re seeing longer dry times but aren’t sure if the vent is the problem.
The inspection catches issues cleaning alone won’t fix: crushed flex duct behind the dryer, improper slope causing condensation pooling, or bird guards that were installed backward and trap lint. In Cotati’s older downtown cottages, we also check for original vent runs that terminate under the house instead of to the exterior, a code violation that was grandfathered in decades ago.
When to Book an Inspection
Schedule an inspection before buying or selling a home in Cotati, after any remodeling that moved walls or appliances, or if your dryer is less than 10 years old but performance has dropped. The borescope shows you exactly what we’re seeing, no guesswork.
Inspection vs. Cleaning
An inspection diagnoses; cleaning fixes. If your vent is fully blocked, we’ll recommend skipping straight to cleaning and will tell you before we start. No charge for the assessment if we proceed with work.
Trusted Brands We Service in Cotati
We carry parts and accessories from Honeywell, Aprilaire, and Abatement Technologies on every truck, so most vent cap replacements and bird guard installations in Cotati are done same-visit without a parts run. For the cleaning itself, we run Rotobrush rotary brush systems and Nikro negative-air machines, the same equipment commercial crews use in hospitals and schools. If your dryer vent terminates through a roof or high wall and needs a specialized cap, we stock galvanized and powder-coated options that hold up to Cotati’s salt-fog exposure better than the big-box versions. The turnaround is fast because we’re not ordering parts; we’ve got them.
Common Dryer Vent Cleaning Problems We See in Cotati Homes
- Moisture-bound lint mats from coastal fog. Cotati’s daily dew-and-dry cycle hardens lint into dense sheets that stick to flex-duct walls and metal seams alike, reducing airflow by 40% or more before most homeowners notice longer dry times.
- Crushed flex duct in Rancho Cotate tracts. The thin plastic flex runs installed in 1980s – 2000s homes kink behind dryers pushed too close to walls, creating a bottleneck that traps lint and overheats the dryer.
- Missing or damaged bird guards on downtown cottages. Original metal vent caps on pre-1960 homes rust through or lose their flappers, inviting birds and squirrels that pack nesting material into the line every spring.
- Improper rerouting after remodels. Cotati’s active real estate market means frequent kitchen and laundry room moves; we’ve found vent runs extended with multiple 90-degree elbows that exceed the 25-foot equivalent length code limit, creating chronic blockage points.

FAQs About Dryer Vent Cleaning in Cotati
Most Cotati appointments are available within 2 – 4 business days, and we schedule specific arrival windows rather than all-day waits. Dispatch runs from our San Francisco Bay Area office with crews already routed through Sonoma County, so Cotati isn’t a long haul for us. Call (361) 326-5060 for the next open slot.
Yes, we work the full city: downtown’s historic hexagon around La Plaza Park, Rancho Cotate and the east-side subdivisions off Southwest Boulevard, and the west-side homes past E. Cotati Avenue toward the 101 corridor. The housing stock changes block by block here, and our crews arrive prepared for either old metal ducts or newer flex runs.
We don’t advertise emergency dispatch for dryer vents because it’s a scheduled maintenance job, not a burst pipe. If you smell burning or your dryer is overheating, unplug it and call us; we’ll prioritize your booking and get a technician out as fast as safely possible. For true fire emergencies, call 911 first.
Our base rates are consistent across Sonoma County, but Cotati’s specific housing mix affects the job scope. Rancho Cotate’s long flex-duct runs often cost more than downtown’s short metal lines, while Santa Rosa’s larger homes average higher due to longer vent paths. We price by the actual job, not the ZIP code.
Every dryer vent cleaning is covered by our 365-Day Done Right Promise in writing. If lint buildup returns due to incomplete cleaning, or if a component we installed fails within a year, we return and make it right at no charge, including a free second visit. No negotiation, no paperwork chase. Call (361) 326-5060 to book your free estimate.
