Dryer vent cleaning in Ontario, CA typically costs $129 – $249 for a standard single-story home, and most jobs are completed within 90 minutes.

We work throughout Ontario’s 91758, 91761, 91762, and 91764 ZIP codes, and we know the mid-century stucco ranches here better than any out-of-town company. Call (855) 341-5439 for a free estimate, and we’ll schedule a camera-backed inspection before you spend a dollar.
Why Limestone Chimney Sweep Is Ontario’s Preferred Dryer Vent Cleaning Company
Most companies that clean dryer vents in Ontario treat it as an add-on. We treat the dryer vent and the chimney as one ventilation system, because in the older ranch homes here they often literally share the same chase. Our techs see the same thing on a monthly basis: a dryer duct routed into a masonry flue that was built for a wood fire in 1962, not a modern appliance pushing moist lint exhaust. That’s Ontario-specific knowledge, and it changes how we clean, inspect, and quote.
Our Dryer Vent Cleaning team runs a camera before we ever recommend additional work. You’ll see the blockage, the crushed flex run, or the disconnected joint on screen before anyone quotes a fix. Limestone is a repair-capable company, not a cleaning-only crew. We stock DuraFlex and professional-grade components locally, so when the camera shows a crushed run off Grove Avenue or a rusted cap near the 91762 line, we can replace it the same visit rather than handing you a report and leaving.
Warren Tilsley built Limestone around a specific standard: never sell a repair the homeowner can’t verify with their own eyes. That matters in Ontario, where old flues and reused chases create a perfect setup for aggressive upselling. We won’t play that game.

Our Dryer Vent Cleaning Services in Ontario
Dryer Vent Cleaning
The core service: we remove lint, palm-frond grit, eucalyptus debris, and animal nesting from the full duct run from dryer to exterior termination. In Ontario’s 1950s-70s ranches, that run is often longer than it should be, snaking through a wall cavity or up an old chimney chase, so a simple brush from the outside won’t reach the packed lint near the dryer. We clean the entire run and verify it with a final camera pass.
Dryer Vent Inspection With Camera Evidence
Every cleaning includes a visual assessment. The camera pass is what separates a legitimate cleaning from a guess. On ranch homes off Grove Avenue and throughout 91761 and 91762, we regularly find crushed flex line, disconnected joints, and lint packed behind the firebox that no amount of surface brushing would reveal. We show you the footage before any repair discussion. Nothing gets upsold. If the run is clean and intact, we tell you that plainly.
DuraFlex Dryer Vent Replacement
When the existing duct is crushed, torn, or made of flammable white vinyl from the 1980s, replacement is the right fix. We carry DuraFlex aluminum transition duct and rigid venting in our service vans, so the replacement happens the same visit. This is not hardware-store foil. DuraFlex is rated for dryer exhaust and holds its shape through the bends and chases common in Ontario’s mid-century construction. We’ll re-seal at the wall and terminate with a proper cap that resists Santa Ana wind-driven debris.
Rusted or Clogged Cap Replacement
The exterior cap is the first thing wind hits. Santa Ana gusts blow palm fronds, eucalyptus bark, and pine needles straight into the vent termination, and the louvered caps on older Ontario homes rust out within a few years. We replace them with louvered or hooded caps that close when the dryer isn’t running. A $40 cap replacement done correctly prevents the entire vent from becoming a lint-and-grit funnel.

Trusted Brands We Service in Ontario
Limestone works with professional-grade materials from DuraFlex, HeatShield, and Gelco, brands that aren’t sitting on the shelf at a big-box store. When an Ontario homeowner needs a full vent replacement, a section of rigid duct, or a liner repair inside an old fireplace chase, we arrive with the component already in the van. That means the fix doesn’t wait for a part to ship. We carry what we need because Ontario’s older homes demand specific transitions at the wall and the firebox, and generic hardware-store parts don’t hold up through a decade of Santa Ana seasons. Warren Tilsley’s approach is simple: stock the right materials, show the customer the evidence, and fix the problem once.
Common Dryer Vent Cleaning Problems We See in Ontario Homes
- Dryer vented into the original fireplace flue. Many Ontario ranches built between 1955 and 1975 have clay-tile flues that were never designed for lint-laden, moist dryer exhaust. That lint coats the tile and hides behind the firebox where a standard dryer vent company never looks.
- Crushed or disconnected flex duct inside the wall chase. The original installers in mid-century tract homes often pushed flexible duct around the firebox and left it kinked. A decade of heat cycling flattens it completely, and the dryer pushes lint into the wall rather than outside.
- Rusted caps clogged with palm and eucalyptus debris. Ontario’s dry summers and gusty wind season fill exterior caps with fibrous debris that traps lint exhaust. The laundry room stays hot and humid, and the dryer runs longer every cycle.
- Birds and rodents nesting at the termination. An open or rusted cap in Ontario’s older neighborhoods is an invitation. We regularly pull nests from vents where the homeowner simply assumed the lint smell was normal for an old house.

AfterPricing for Dryer Vent Cleaning in Ontario, CA
A standard dryer vent cleaning for a single-story Ontario ranch typically runs $129 – $199, depending on roof access and run length. Two-story homes or exterior terminations above the roofline usually add $30 – $50 because ladder and roof work are involved. If we replace flexible duct or a cap during the same visit, parts run $40 – $150 depending on what the camera shows. A full DuraFlex vent replacement in a long mid-century chase can reach $300 – $450 when the existing run is unsalvageable. Every quote comes after we show you the camera footage. You decide based on what you see, not what we claim. Call (855) 341-5439 for a free estimate before you book.

FAQs – Dryer Vent Cleaning in Ontario
In most cases, no. Ontario’s 1950s-70s stucco ranches often routed dryer exhaust into the same masonry chase as the fireplace, and those flues were built for wood smoke, not moist lint-laden dryer exhaust. The lint coats the clay tile or raw masonry, accumulates behind the firebox, and creates a fire and moisture hazard. A camera inspection will show exactly what’s inside your run. Call (855) 341-5439 and we’ll show you the footage before recommending anything.
Because the dryer vent and fireplace flue are sharing the same chase or back-drafting into each other in many Ontario ranches. When the flue is blocked or capped incorrectly, dryer exhaust has nowhere to go, so it pushes back into the laundry room carrying fireplace soot and creosote odor with it. The lint might also be absorbing that smell and re-releasing it every cycle. A camera run through the vent shows the path and the blockage in minutes.
Never. If a technician tells you the flue needs a reline without putting a camera scope down the run and showing you the damage on screen, walk away. In Ontario’s older homes, aggressive reline quotes target homeowners who can’t see inside their walls. We show the footage first. If the duct is crushed and needs DuraFlex replacement, you’ll see it. If the original run is intact and just needs cleaning, we’ll tell you that too. You approve every fix based on evidence.
Once per year for most Ontario homes. Hot, dry summers mean the vent sits idle and collects dust, insect debris, and wind-blown grit. When fall hits and laundry loads pick up, that accumulated material compacts under moist exhaust and the blockage forms fast. Homes with long vent runs, rooftop terminations, or shared fireplace chases may need cleaning twice a year. If you’re in 91761 or 91762 and the previous owner rarely used the dryer, start with a camera inspection and clean from there.
Clothes taking more than one full cycle to dry, a hot laundry room with a musty or fireplace smell, visible lint around the dryer base or exterior cap, and a dryer that shuts off on its high-limit switch. In Ontario, another tell is a vent cap that doesn’t open and close freely, since Santa Ana grit jams the louver. Any of these means a restriction is forming. Call (855) 341-5439 for a free estimate. We’ll look before we quote.
