Fast, Reliable Dryer Vent Cleaning Across Ontario
Dryer vent cleaning in Ontario, CA typically runs $110 – $190 for a standard single-story home and $150 – $240 for two-story homes with longer duct runs.

Call Norm Castillo and the Ashwood Chimney Sweep team at (833) 805-3229 for a straight answer and a free estimate.
We work throughout Ontario’s 91758, 91761, 91762, and 91764 ZIP codes every week. Our techs know the tract-home layouts, the tight laundry closets, and the particular way this city’s Santa Ana winds push debris into vent hoods. This isn’t a side service for us. It’s a fire-safety job we take as seriously as any chimney repair.
Why Ashwood Chimney Sweep Is Ontario’s Preferred Dryer Vent Cleaning Company
Ontario homeowners call us for one reason mostly: they want a contractor who treats the dryer vent as part of the home’s ventilation system, not an afterthought. Norm Castillo built this company around that principle. A dryer vent that terminates in an attic or crawlspace, which we see regularly in Ontario’s older corridors, is a lint fire waiting for an ignition source. Most homeowners never see it because it’s hidden behind drywall or buried under insulation.
We pull camera footage on every vent we clean. You see what we see before we recommend anything. If a duct is crushed behind the dryer, we show you the image. If a bird pushed a nest into the hood during a Santa Ana event, you’ll watch us pull it out. That transparency is why Ontario customers keep us on speed dial for annual maintenance.
We’re based in Fontana, so a run out to Ontario takes us 20 – 30 minutes on the 10 or the 60, depending on traffic. That means faster scheduling for homeowners near Ontario Mills, the 91764 subdivisions south of the 60, or the older grid near Euclid Avenue. One call covers assessment, cleaning, and repair if needed. No hand-off to another crew.

Our Dryer Vent Cleaning Services in Ontario
Dryer Vent Cleaning and Inspection
The core service. We disconnect the dryer, run a rotary brush and HEPA-filtered vacuum through the full duct run, and finish with a camera inspection. In Ontario’s 91761 and 91764 tract homes, we’re specifically checking whether the vent terminates outdoors at all. If it dumps into the attic, you need to know that. The cleaning removes the lint. The camera tells you whether the system was ever built right.
Dryer Vent Repair and Replacement
When we find a crushed section behind the dryer or a disconnected joint inside the wall cavity, we repair it with smooth aluminum or rigid metal duct, never the flimsy foil or vinyl flex that shouldered its way into so many 1980s Ontario builds. We stock Famco vent hoods and Copperfield duct components on the truck, so most repairs happen same-day. You get a system that moves air the way it should.
Pest and Debris Removal from Exterior Vent Hoods
Ontario’s position in the Santa Ana wind corridor means vent hoods collect sticks, leaves, dust, and the occasional finch nest between annual cleanings. A hood that won’t open traps hot, damp air inside the duct. We clear the obstruction, inspect the damper, and can install a pest-resistant hood with a tighter mesh. This is one of the most common calls we get in the weeks after a big wind event.
Attic and Crawlspace Dryer Vent Correction
This is the one that matters in Ontario. Homes built between the late 1940s and early 1980s across the 91761, 91762, and 91764 corridors often have dryer vents that simply stop in the attic or crawlspace. Every load of laundry dumps warm, lint-heavy air into a concealed space. We can reroute the vent to terminate through an exterior wall or the roofline. It’s more involved than a standard cleaning, but it eliminates a fire risk that has been festering since the day the house was built.

Trusted Brands We Service in Ontario
We don’t install the kind of materials you can grab off a home-center shelf. Our Dryer Vent Cleaning team carries Famco ventilation components and Copperfield duct hardware, the same professional-trade brands specified by certified chimney and ventilation contractors nationwide. In practice, that means the replacement hood we install on your Ontario home won’t rust through in three summers of inland heat. The duct we hang won’t crush the first time someone pushes the dryer back against the wall. We keep common replacement parts stocked for Ontario service calls, so we’re not driving back to a supplier while you wait.

AfterCommon Dryer Vent Cleaning Problems We See in Ontario Homes
- Vents that terminate inside the attic or crawlspace. This is the loudest problem we see in Ontario’s post-WWII and 1980s housing stock. Lint and moisture accumulate in hidden spaces, and most homeowners have no idea until we put a camera on it.
- Bird nests and Santa Ana debris packed into exterior hoods. Strong wind events in the Inland Empire push sticks, leaves, and nesting material into vent terminations. One nest can block 80% of airflow and make your dryer run dangerously hot.
- Crushed or disconnected foil duct behind the dryer. Tight 1980s laundry closets force the dryer hard against the wall. The flexible foil crushes, the airflow drops, and lint starts escaping into the room behind the unit.
- Painted-shut or heat-warped vent hood dampers. Inland summer heat takes a toll on plastic dampers. When the damper won’t open, the dryer pushes against a closed door and overheats. We replace them with metal, pest-resistant hoods that hold up.
Pricing for Dryer Vent Cleaning in Ontario, CA
A standard dryer vent cleaning in Ontario runs $110 – $190 for single-story homes with a straight or short duct run. Two-story homes in the newer subdivisions south of the 60 or east toward the 15 typically run $150 – $240 because the duct run is longer and the exterior vent sits higher. If we find a crushed section or need to reroute a vent that terminates in the attic, repair work is quoted after the camera inspection. You’ll see the footage first. We give a flat price before any repair begins. Estimates are free. Call (833) 805-3229 and we’ll give you an exact number for your specific home.

FAQs – Dryer Vent Cleaning in Ontario
Santa Ana winds, which push down through the Cajon Pass and across Ontario’s flat grid, carry dust, twigs, leaves, and dry grass straight into exterior vent hoods. Many Ontario homes have vent terminations on the west or north side, directly in the path of these wind events. One strong wind day can pack a hood with enough debris to choke airflow, and birds often follow the sheltered opening. A pest-resistant hood helps, but an annual check after wind season is the practical answer. Call (833) 805-3229 to schedule one.
Yes, and it’s not just about age. 1980s tract homes in Ontario were often built with tight laundry closets and flexible foil or plastic duct that crushes behind the dryer. Worse, many vents from that era terminate in the attic or crawlspace instead of outside. Both conditions are common in the 91761 and 91764 corridors, and both create real fire and moisture risk. The only way to know what you have is a camera inspection, and we do that on every cleaning.
If the vent hood doesn’t open or you can’t feel warm air moving from the termination while the dryer runs, that’s a clog. Clothes taking two full cycles to dry, a burning smell when the dryer runs, or the top of the dryer feeling unusually hot are all signs. And if your vent terminates in the attic, you’ll never see lint outside because it’s collecting inside your house. We can camera-inspect the entire run and show you exactly where the blockage is.
Yes. We’re a full-service ventilation company, so if your fireplace or flue is due for a sweep, we add it to the same trip. Ontario’s winters are mild enough that gas-log fireplaces often go a few years between cleanings, but chimneys still collect dust, bird debris, and the odd creosote from occasional wood fires. One visit covers both systems, and you only book one crew. Call (833) 805-3229 to set up a combined service.
Crushed and disconnected duct behind the dryer. The 91762 ZIP runs right through central Ontario, where you’ll find a lot of older single-story homes with narrow laundry nooks. The dryer gets shoved back against the wall, the flex duct collapses, and hot lint-heavy air leaks into the home. We fix it with rigid smooth aluminum duct and mount the dryer with clearance so it doesn’t happen again.
