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 $150-$280 for a standard single-family home, and most jobs are completed in under two hours. We’re the Dryer Vent Cleaning team that serves San Lorenzo from our Bay Area dispatch office, with crews familiar with the Bohannon-era ranch homes that make up most of this city’s housing stock. Call us at (469) 972-3151 for a free written estimate before any work begins.
San Lorenzo homeowners deal with a specific problem most inland East Bay residents don’t: dryer vent runs that terminate in damp, shallow crawl spaces where lint absorbs ground moisture and hardens into dense, felt-like blockages. Our technicians have worked the San Lorenzo Village tract homes along Via Alta, Lewelling Boulevard, and the streets near San Lorenzo Creek long enough to know where the trouble spots hide. We don’t guess. We run a camera, show you what we find, and put the price in writing before touching a tool.
Why Kestrel Air Duct Cleaning Is San Lorenzo’s Preferred Dryer Vent Cleaning Company
We’ve built our reputation in San Lorenzo on showing up in the window we promised and leaving the job site cleaner than we found it. The Kingswell Way, our code of conduct on every visit, requires it.
Our customers in San Lorenzo Village and the neighborhoods near Hesperian Boulevard and Washington Avenue have left us strong local feedback. We don’t publish review counts we haven’t verified, but our standing in the East Bay is built on repeat calls from the same streets and referrals to neighbors.
Dispatch and scheduling for San Lorenzo run from our Bay Area office, with crews routed to minimize wait times across the southern East Bay. Most San Lorenzo appointments are set within a few days, not weeks.
The local knowledge matters here more than in newer cities. A technician who doesn’t recognize the Bohannon crawl-space layout, the low terminus points, and the moisture patterns off San Lorenzo Creek is likely to brush out what looks like a clean vent and miss the saturated flex duct sagging against damp ground six feet from the dryer.
Dryer Vent Cleaning Company in San Lorenzo
Dryer Vent Cleaning Company work in San Lorenzo means more than pushing a brush through a tube. Most homes here need source removal with rotary brush agitation, tools that physically scrub the duct wall to break loose lint that has hardened against damp metal, followed by negative-air extraction, which is a high-powered vacuum that pulls dislodged debris out of the system rather than letting it drift into your laundry room or crawl space. A typical dryer vent cleaning in San Lorenzo runs $150-$220 for a straight run under 15 feet; longer runs, multiple bends, or severe blockage push the range to $220-$280.
San Lorenzo homeowners should schedule cleaning when the dryer takes more than one cycle, the laundry room feels humid, or there’s a faint musty smell after running a load. In this city’s climate, these symptoms usually mean moisture-matted lint, not just dry fuzz.
Rotary Brush Agitation and Negative-Air Setup
We use Rotobrush rotary systems to scrub the duct wall, then pull loosened debris with Nikro negative-pressure units. The Abatement Technologies HEPA filtration captures particles so they don’t settle in your crawl space or living area. This matters in San Lorenzo’s older homes, where the laundry room often sits adjacent to main living spaces with minimal separation.
Post-Cleaning Flow Verification
After agitation and extraction, we measure airflow at the exterior termination. A properly cleared vent in a San Lorenzo Bohannon ranch should read within manufacturer spec. If it doesn’t, we keep investigating until we find the kink, sag, or disconnected joint that brushing alone won’t fix.
Dryer Vent Inspection in San Lorenzo
Dryer Vent Inspection in San Lorenzo is the step too many competitors skip, and it’s the reason homeowners call us after another company’s “cleaning” failed to solve the problem. A proper inspection here means a camera run through the full length of the duct, with the technician noting corrosion, moisture staining, sagging flex, disconnected joints, and whether the termination point sits below grade or in a damp crawl space. Inspections in San Lorenzo typically cost $89-$140 as a standalone service; they’re included at no charge when bundled with cleaning.
We recommend an inspection first when there’s been recent water intrusion in the crawl space, when the dryer has never performed well even after previous cleanings, or when a homeowner suspects the vent run was rerouted poorly during a past renovation.
Camera Documentation for Insurance
Our inspection reports include dated photo and video capture of the duct interior. For San Lorenzo homeowners filing claims after crawl-space flooding, this documentation shows whether a section is cleanable or structurally compromised by moisture. Insurers need that distinction. We provide it in writing.
Moisture Assessment and Replacement Recommendations
When a camera reveals saturated flex duct, corroded metal, or active mold colonization, cleaning becomes the wrong call. We’ll show you the footage, explain why replacement is necessary, and quote that work separately. No bundled bait-and-switch. Two distinct prices for two distinct jobs.
Trusted Brands We Service in San Lorenzo
We clean and inspect venting connected to all major dryer manufacturers, and we stock replacement components from Honeywell and Aprilaire for San Lorenzo homeowners who want upgraded filtration or humidity control in the laundry space. Our Nikro and Rotobrush equipment handles the agitation and extraction; Abatement Technologies HEPA units keep the work contained. For properties near the creek corridor with chronic dampness, we can source Guardsman-rated moisture barriers and improved vent caps designed to resist the marine air that accelerates corrosion on standard hardware.
Common Dryer Vent Cleaning Problems We See in San Lorenzo Homes
- Damp-mat lint blockages at low terminus points. In San Lorenzo Village crawl spaces along the creek drainage, lint absorbs ground moisture and compresses into a dense felt block. Standard brushing won’t touch it. We need rotary agitation and sustained negative pressure to break it free.
- Sagged or kinked flex duct from 1970s-80s retrofits. The Bohannon-era galvanized runs that were later covered with flex duct now sag low to grade, creating pockets where lint and water pool. The dryer labors, the vent never fully clears, and homeowners get stuck in a cycle of repeated “cleanings” that miss the structural problem.
- Disconnected joints hidden behind laundry room walls or in crawl spaces. Ground moisture weakens tape and clamps. A joint separates. Half the exhaust vents into the crawl space instead of outside. The dryer works twice as hard. Energy bills climb. We find these with the camera, not by guesswork.
- Post-storm saturated duct sections that need replacement, not cleaning. After water wicks up through a poorly vented crawl space, a section of flex duct can hold moisture for weeks. Cleaning it spreads mold spores and leaves a weakened structure. We document the saturation, recommend replacement, and provide the insurer-ready report.
Pricing for Dryer Vent Cleaning in San Lorenzo, CA
Most San Lorenzo dryer vent cleanings fall between $150 and $280, with the majority of standard jobs landing in the $150-$220 range. Factors that move the price: total duct length, number of bends or direction changes, accessibility of the crawl space or exterior termination, and whether the blockage is dry lint or moisture-compacted material requiring extended agitation time.
Dryer vent inspections run $89-$140 alone, or zero when bundled with cleaning. Vent rerouting, cap replacement, or bird guard installation are quoted separately after inspection, with the written price in your hands before work starts. We don’t do per-vent pricing. We don’t do surprise add-ons at the door. One flat price per system, agreed in writing, every time.
Call (469) 972-3151 for a free estimate. We’ll ask about your home’s age, the dryer’s location relative to exterior walls, and any recent water or performance issues. That lets us give you an accurate range before we schedule.

FAQs About Dryer Vent Cleaning in San Lorenzo
If the duct is intact with surface moisture and no structural damage, cleaning with full source removal and HEPA containment is appropriate. If the camera shows saturated flex duct, corroded metal, or active mold colonization, that section must be replaced; cleaning it would spread contamination and leave a weakened structure. We document both conditions with dated video for your insurer. Call (469) 972-3151 and we’ll inspect before quoting either path.
San Lorenzo’s marine air and damp crawl spaces along the creek corridor keep lint wet, causing it to mat and harden rather than stay fluffy and pass through. Pleasanton’s drier inland climate produces loose, dry lint that brushes out easily. Your vent needs more aggressive agitation and more frequent inspection, not just a standard brush pass. We can set a maintenance interval based on your actual conditions.
Yes. The retrofitted flex duct in these homes has often sagged, kinked, or disconnected at joints after decades of ground moisture exposure. We inspect with a camera first, support any sagging sections before agitation, and verify structural integrity before applying rotary brush force that could tear weakened material. Rushing this step in a Bohannon-era home causes damage that wasn’t there before we arrived.
We provide a dated video inspection showing pre-work condition, moisture meter readings where applicable, photo documentation of saturated or compromised sections, and a written statement distinguishing cleanable debris from structurally failed duct requiring replacement. This package has been accepted by San Lorenzo homeowners’ insurers because it answers the specific question adjusters ask: why was replacement necessary rather than cleaning? Call (469) 972-3151 to schedule the inspection.
Yes, and the risk profile is specific here. Lint is already combustible; when it mats with moisture and then partially dries, it forms dense pockets that trap heat and restrict airflow. The older electrical systems in some Bohannon-era homes, combined with dryers working overtime due to blockage, add strain. The U.S. Fire Administration identifies dryer vent failure as a leading cause of residential fires. In San Lorenzo’s housing stock, the added factor is that blockages are often hidden in inaccessible crawl spaces where a homeowner wouldn’t smell overheating until it’s severe. Annual inspection is the prudent standard.
