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 Bruno
Dryer vent cleaning in San Bruno typically runs $180-$340 for a standard single-family home, and most jobs are completed in under two hours. If your dryer takes two cycles to finish a load or your laundry room smells musty, a clogged vent is the likely culprit. Call (469) 972-3151 for a free estimate and a written price before any work begins.
We serve San Bruno homeowners from our San Francisco Bay Area dispatch office, with crews covering the full city from the Mills Park neighborhood to the hillside tracts west of El Camino Real. San Bruno’s location in the San Bruno Gap means your dryer vent faces conditions that inland Peninsula cities simply don’t: cold, moist marine air funnels through that coastal range break year-round, keeping vent runs damp and turning lint into dense, matted clumps instead of dry, loose debris. That local climate reality changes how the work needs to be done, and it’s why we bring Rotobrush rotary agitation tools and Nikro negative-pressure extraction to every San Bruno job, not just a shop vac and a prayer.
Why Kestrel Air Duct Cleaning Is San Bruno’s Preferred Dryer Vent Cleaning Company
We’ve built our reputation in San Bruno on showing up in the window we promised and putting the price in writing before a tool comes out of the van.

Dale Whitmore oversees every location in our network, and that same standard applies whether we’re working in a 1950s ranch near San Bruno Avenue or a newer build up toward Skyline College.
Our San Bruno customers call back because the 365-Day Done Right Promise means something you can hold in your hand. If the work falls short within that year, we return and make it right at no charge. No “courtesy visit” language, no discretion. It’s documented on every invoice.

Dryer Vent Cleaning Service in San Bruno
Dryer Vent Cleaning Service in San Bruno means more than blowing air through a tube. Our process starts with a camera inspection of the full vent run, from the back of your dryer to the exterior wall cap. We use Rotobrush rotary brush systems to physically dislodge lint that’s matted to the duct walls, then Nikro negative-pressure units pull that debris out of your home entirely. Abatement Technologies HEPA filtration captures the fine particles so they don’t resettle in your laundry room or living space. For a typical San Bruno single-family home, Dryer Vent Cleaning Service runs $180-$240; homes with longer runs, multiple bends, or crawl-space access issues may reach $280-$340.
When San Bruno Homeowners Need This Service
Call us when your dryer needs two cycles, when the exterior vent flap barely opens during a cycle, or when you notice a musty smell in the laundry area. In San Bruno’s marine microclimate, these symptoms often point to moisture-compacted lint that air-only cleaning won’t touch. Our Dryer Vent Cleaning team has cleared vent runs in homes from Rollingwood to Lomita Park, and the pattern is consistent: damp lint, sagging flex duct, and collar joints stained with condensation.
What the Camera Inspection Reveals
We run a borescope camera through the full vent path before and after cleaning. In San Bruno’s postwar housing stock, we regularly find sagging flex duct in crawl spaces, disconnected runs at coupling points, and exterior caps clogged with lint that’s absorbed years of fog-borne moisture. The camera shows you exactly what we’re dealing with, and the after photos prove what we removed.
Dryer Vent Installation in San Bruno
Dryer Vent Installation in San Bruno addresses the root problem when your existing vent run is beyond cleaning: crushed flex duct, improper routing through multiple 90-degree bends, or dangerous plastic or foil transition hoses that violate current building codes. We replace failed sections with rigid metal duct sized to your dryer’s CFM rating, seal all joints with high-temperature foil tape, and install a proper exterior wall cap with a backdraft damper. Standard Dryer Vent Installation in San Bruno runs $320-$480 for a straightforward through-wall replacement; complex rerouting through crawl spaces or attic runs can reach $550-$780.
Code-Compliant Materials and Routing
San Bruno follows California Building Code and local amendments that prohibit plastic or thin-foil transition ducts and limit the number of elbows in a vent run. Our installations use 26-gauge galvanized steel or aluminum rigid duct, properly supported to prevent sagging that traps lint. We verify the total equivalent duct length against your dryer’s manufacturer specifications so the appliance can actually move air.
Bird Guard and Vent Cap Options
We install Guardsman vent caps with integrated bird guards and backdraft dampers, which keep Pacific fog, nesting birds, and wind-driven rain out of your vent termination. For homes near SFO’s flight corridors, where fine particulate is an ongoing concern, a quality cap with a fine mesh screen reduces exterior contamination without restricting airflow.
Trusted Brands We Service in San Bruno
Our technicians carry common dryer vent components and can source same-day replacements for most installations. We stock rigid metal duct, high-temperature foil tape, and wall caps from major manufacturers, and we install Aprilaire and Guardsman filtration accessories for homeowners who want to maintain cleaner indoor air between service visits. For the extraction work itself, our Rotobrush, Nikro, and Abatement Technologies equipment is maintained to manufacturer specs, not jury-rigged with hardware-store attachments. When you call (469) 972-3151, we can confirm parts availability for your specific installation before we arrive.
Common Dryer Vent Cleaning Problems We See in San Bruno Homes
- Moisture-matted lint from the San Bruno Gap. The persistent marine air flowing through this coastal break keeps vent runs humid enough that lint clumps into heavy, damp wads. A quick blow-through with compressed air won’t break these loose; rotary brush agitation and negative-pressure extraction are required to actually remove the material.
- Sagging flex duct in hillside crawl spaces. In the neighborhoods west of El Camino Real, where fog sits longest, we find flex duct runs that have sagged between supports, creating low points where condensation pools and lint accumulates. These runs often show staining at every collar joint and need replacement, not just cleaning.
- Airport-adjacent particulate buildup. Fine particulate matter from SFO’s active flight corridors mixes with damp lint in the vent pathway, creating a sticky residue on the blower wheel and inside the duct. Surface-only cleaning leaves this residue behind; source removal with HEPA-filtered negative pressure is the only method that meets NADCA standards.
- Undersized or blocked exterior caps. Many San Bruno homes still have original vent caps from the 1950s or 1960s with flappers that have corroded shut or screens that have clogged with lint and coastal salt residue. We replace these with modern, code-compliant caps that actually open under dryer airflow.
Pricing for Dryer Vent Cleaning in San Bruno, CA
Most San Bruno homeowners pay between $180 and $340 for complete dryer vent cleaning, depending on run length, access difficulty, and whether sections need replacement. Here’s how typical jobs break down:

| Vent rerouting or partial replacement | $320-$480 |
| Full replacement with rigid metal duct | $550-$780 |
What moves you up or down in these ranges: the number of 90-degree bends, whether we can access the full run from inside or need to enter a crawl space, and whether the existing duct is salvageable or needs replacement.

FAQs About Dryer Vent Cleaning in San Bruno
The San Bruno Gap funnels cold, moist Pacific air directly through your city, keeping vent runs damp enough that lint mats into dense clumps instead of staying loose and blowing free. San Mateo sits slightly inland and doesn’t get hit with the same intensity of marine air, so lint there tends to stay drier and more mobile. That microclimate difference is real, and it means San Bruno vents need more thorough agitation cleaning, not just air blowing. Call (469) 972-3151 and we’ll show you exactly what’s in your run.
Yes. San Bruno’s postwar tract housing often has original or first-generation flex duct runs in crawl spaces, with poorly sealed joints and routing that doesn’t meet current code. We start with a camera inspection to map what you’ve actually got, then clean or replace based on what we find, not a one-size-fits-all protocol. The 365-Day Done Right Promise covers our work regardless of your home’s age.
No. Fogging deposits a chemical mist on surfaces but does nothing to remove the matted lint and moisture that’s causing your problem. Source removal, physically extracting the debris with rotary brush agitation and negative-pressure extraction, is the only method that addresses the root cause. We don’t sell fogging as a solution because it isn’t one.
A disconnected vent run in a crawl space often shows these signs: your dryer still “works” but lint accumulates under the house or in the crawl space; the laundry room gets humid during cycles; or you notice musty odors even after cleaning the lint trap. Our camera inspection reveals disconnections, crushed sections, and sagging low points that aren’t visible from either end. We show you the footage before we quote any repair.
Dryer vent cleaning addresses only the exhaust path from your dryer to the exterior wall cap. Full air duct cleaning covers the supply and return ductwork of your central HVAC system, including registers, grilles, and the air handler. They’re separate systems with separate access points, though both benefit from the same source-removal methods: rotary brush agitation, negative-pressure extraction, and HEPA filtration. We offer both services and can bundle them if your home needs both.
