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 Lorenzo
Dryer vent cleaning in San Lorenzo typically runs $180 – $340 for a standard residential system, and most jobs are completed in under two hours with the dryer back in service the same day. If your dryer is taking two cycles to finish a load or the laundry room smells musty, the vent run is likely blocked with lint, crushed in a tight attic chase, or disconnected entirely. Call us at (361) 326-5060 for a free estimate and written price before any work starts.
We’ve worked in San Lorenzo’s Eichler tracts off Via Alamitos and the ranch neighborhoods near Lewelling Boulevard enough to know what we’re walking into: shallow-pitch roofs, original 1950s – 1970s framing, and dryer vents that share cramped attic chases with aging supply ducts. Our crews carry rigid UL-listed replacement pipe, camera inspection gear, and the patience to feed hoses through spaces where a standard cleaning outfit would give up. Dispatch and scheduling are coordinated from our San Francisco Bay Area office, but the technicians serving San Lorenzo live and work locally, not dispatched from two counties away.
Why Hollis Air Duct Cleaning Is San Lorenzo’s Preferred Dryer Vent Cleaning Company
San Lorenzo homeowners have told us the same story for twenty years: the last crew quoted one price on the phone, then added “per vent” charges at the door, or showed up late in an unmarked van and left lint scattered through the attic. We don’t work that way. Every Hollis job starts with a written price before any tool touches your vent, and every technician is background-checked, uniformed, and held to The Garrison Code: arrive inside the window, price in writing, complete the job by the book, leave the site clean.
Our 365-Day Done Right Promise covers every dryer vent cleaning in San Lorenzo in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. That’s not a verbal assurance; it’s printed on every invoice.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday to schedule. When you call (361) 326-5060, you’ll speak to someone who can book your San Lorenzo appointment and confirm your written estimate.
Dryer Vent Inspection in San Lorenzo
Dryer Vent Inspection in San Lorenzo is where we always start, because guessing at a blockage location in a 1962 Eichler or a 1970s ranch with shallow attic clearance is a waste of your time and ours. A proper inspection runs $120 – $180 and includes camera scoping of the full vent run from the transition boot behind the dryer to the exterior wall cap, airflow measurement with a manometer, and a written report of what we found, what it will cost to fix, and whether the vent meets current California fire safety standards.
We recommend a Dryer Vent Inspection for any San Lorenzo home where the dryer takes longer than 50 minutes per load, where the exterior cap shows no airflow during operation, or where there’s a musty smell in the laundry room that suggests lint is wet and packed in a low section of the run. In the Eichler neighborhoods off Via Alamitos, we also flag original asbestos-wrapped transition tape for proper handling before any cleaning or re-routing begins.
Camera Scoping and Airflow Testing
Our inspection cameras are small enough to navigate the crushed flex and tight corners common in San Lorenzo’s shallow attic chases. We record what we see and show it to you. The manometer reading tells us exactly how restricted the airflow is, in cubic feet per minute, so there’s no debate about whether the vent needs cleaning or replacement.
Written Report and Upfront Pricing
After inspection, you get a single-page report with photos, the airflow reading, and one flat price to correct any problems we found. No per-vent pricing, no add-ons at the door. If the vent is clean and clear, you pay only the inspection fee and we leave.
Commercial Dryer Vent Cleaning in San Lorenzo
Commercial Dryer Vent Cleaning in San Lorenzo covers multi-unit buildings, laundromats, assisted-living facilities, and property management portfolios where a single clogged vent affects dozens of residents or puts an entire structure at fire risk. Commercial systems in San Lorenzo typically cost $280 – $550 per building depending on the number of units, the length of the shared riser, and whether we need to access rooftop termination points on low-slope roofs common to 1960s apartment construction.
We schedule commercial work during off-peak hours to minimize disruption, and we provide a certificate of cleaning for property insurance and fire marshal documentation. Our crews use Nikro negative-air machines and Rotobrush rotary systems to handle long commercial runs that residential equipment cannot reach.
Multi-Unit Riser Cleaning
Shared dryer vent risers in older San Lorenzo apartment buildings accumulate lint from multiple units over years, creating a fire hazard that individual tenants cannot address. We clean the full riser from the rooftop cap to the lowest connection, verify airflow at each unit, and document the work for your insurance carrier.
Property Management Programs
For San Lorenzo property managers, we offer scheduled annual inspections and cleanings with written pricing locked in advance. This prevents emergency calls, extends dryer life across your portfolio, and satisfies most insurance requirements for common-area fire prevention.
Trusted Brands We Service in San Lorenzo
We stock replacement components from Honeywell, Aprilaire, and Abatement Technologies for San Lorenzo customers, which means most vent repairs and cap replacements don’t require a second trip. Our rotary brush systems are from Rotobrush, and our negative-air equipment is from Nikro, the same brands commercial duct crews use in hospitals and schools. When we re-route a crushed flex vent with rigid pipe or install a bird guard on your exterior cap, the materials are UL-listed and rated for California’s fire safety codes, not hardware-store specials that degrade in San Lorenzo’s marine-layer dampness.
Common Dryer Vent Cleaning Problems We See in San Lorenzo Homes
- Crushed flex vent in shallow attic chases. The low-clearance framing in 1950s – 1970s San Lorenzo ranch and Eichler homes leaves no room for proper flex vent routing. We regularly find the duct pinched against a rafter or joist, reducing airflow by half and trapping lint where the homeowner can’t see it.
- Wet, matted lint from marine-layer condensation. San Lorenzo’s fog belt keeps uninsulated attic spaces damp for months. Lint absorbs this moisture and adheres to the duct wall like paste, so a quick brush pass won’t clear it. We use agitation and negative-air extraction to remove packed material.
- Asbestos-wrapped transition tape in Eichler tracts. Original dryer vent connections in Via Alamitos Eichler homes were sealed with tape that contains asbestos. Disturbing it without proper handling spreads fibers through the laundry room and attic. We identify this material during inspection and coordinate safe abatement before re-routing.
- Disconnected or rodent-damaged vents dumping into attics. San Lorenzo’s original open-eave construction invites pests into uninsulated attics. We’ve found flex vents chewed through by rats and squirrels, blowing hot, lint-laden air directly into the attic space instead of outdoors. This is a fire hazard and a moisture problem combined.
Pricing for Dryer Vent Cleaning in San Lorenzo, CA
A standard residential dryer vent cleaning in San Lorenzo runs $180 – $240 for a straight, accessible run that needs brushing and debris removal. If we find a crushed or disconnected vent that requires re-routing with rigid pipe, replacement of the transition boot, or installation of a new wall cap, the total typically falls between $280 – $340. Commercial multi-unit systems start at $280 and scale with the number of units and riser length.
What moves the price: the length and accessibility of the vent run, whether the duct is rigid or flex, the condition of the exterior cap, and whether we encounter asbestos-wrapped material requiring special handling. We inspect first, quote in writing, and do not start work until you approve the flat price. Estimates are free. Call (361) 326-5060 to schedule.

FAQs About Dryer Vent Cleaning in San Lorenzo
Restricted airflow from lint buildup, a crushed vent, or a disconnected duct is the cause in nearly every case we see. In San Lorenzo’s older homes, the shallow attic chase often crimps the flex vent or marine-layer dampness mats lint against the duct wall so it doesn’t blow clear. Call (361) 326-5060 for an inspection and written repair quote.
Yes, we identify asbestos-wrapped transition tape during inspection and coordinate proper abatement before any cleaning or re-routing. We do not disturb this material without containment protocols in place. The inspection fee covers identification; abatement is quoted separately based on the scope.
Every 12 – 18 months for most San Lorenzo homes, and annually if you dry heavy loads frequently or live in a multi-unit building with a shared riser. The marine layer adds moisture that mats lint, and East Bay wildfire ash can infiltrate attic spaces and compound buildup in the vent path.
1950s – 1970s ranch and Eichler homes in San Lorenzo were built with shallow-pitch roofs and minimal attic clearance. The dryer vent often shares a cramped chase with HVAC ducts, requiring flexible camera equipment, patient hose handling, and experience with original framing that newer suburban crews rarely encounter. We’ve worked these spaces enough to know the shortcuts to avoid.
Yes, because the combination of older construction, uninsulated attic runs, and marine-layer dampness creates a higher fire risk and mold risk than in newer homes with straight, rigid venting and conditioned spaces. A clogged vent in San Lorenzo is more likely to be wet, packed, and located near combustible original materials. The 365-Day Done Right Promise covers our work in writing if anything fails after we leave.
