Fast, Reliable Dryer Vent Cleaning Across Westmont
A clogged dryer vent in Westmont usually costs between $140 and $225 to clean properly, and the job takes about an hour from setup to final airflow test. That’s the honest range we quote over the phone for single-story homes here, and it holds unless there’s a bird nest, disconnected duct, or crawlspace termination involved. If you’ve noticed clothes taking two cycles to dry or a burning smell near the laundry room, call (855) 382-6159 and we’ll get a tech out to your block, usually within a few days.
We know Westmont’s housing stock because we work it constantly. These are 1940s and 1950s wood-frame bungalows and low stucco duplexes where the dryer vent often wasn’t installed with the house – it was added decades later, sometimes badly. That matters when we diagnose airflow problems. Our Dryer Vent Cleaning team treats every Westmont job as a fire-prevention service first, because that’s what the homes here actually require.
Why Corona Chimney Sweep Is Westmont’s Preferred Dryer Vent Cleaning Company
Most Westmont homeowners don’t realize their dryer vent and chimney share a common failure point: the roof jack. On the 90047 blocks around Western Avenue and Century Boulevard, we see original roof jack flashing rusted through on both systems. When the flashing fails, the dryer vent often gets disconnected inside the wall or crawlspace, and lint starts accumulating where you can’t see it. A sweep-only company will clean the vent and leave. We repair what we find.
Nolan Ferris built Corona Chimney Sweep around a simple idea: one provider for every venting hazard in a house. That means when our tech finds a disconnected dryer duct in a Westmont crawlspace, we reconnect it with DuraFlex semi-rigid duct on the spot. When we find a bird nest blocking the exterior hood, we remove it and install a termination cap with a proper backdraft damper. No referral to a third company. No limbo while you wait for someone else to show up.
Our technicians are the same crew that works on combustion venting – chimney flues, furnace exhaust, gas appliance venting. That cross-training matters in Westmont because many crawlspace dryer vent problems mimic flue problems. The airflow math is the same. We use a manometer to measure static pressure and confirm the system moves air at the rate the manufacturer requires before we call the job done.

Our Dryer Vent Cleaning Services in Westmont
Dryer Vent Cleaning
We run a rotary brush and high-CFM vacuum through the full duct run, from dryer exhaust port to exterior termination. In Westmont’s tight laundry closets – often shared with a water heater in these older bungalows – we check the transition duct too, because that’s where most lint fires start. We finish with an airflow test and show you the before-and-after readings. A routine clean on a short, straight vent might take 45 minutes. A long run with multiple elbows through an old wall cavity takes longer, and we’ll tell you that before we start.

Dryer Vent Installation
Westmont homes built in the 1940s and 1950s often have dryer vents that were retrofitted with whatever was cheapest at the time – white plastic flex duct, drywall screws, duct tape. We replace those with rigid aluminum or DuraFlex semi-rigid duct, properly sealed at the joints and terminated at the exterior with a louvered or flap hood. When the original roof jack has failed, we install a dedicated termination and flashing that won’t leak into the wall cavity.

Bird Nest Removal
Starlings and pigeons love the warm exhaust coming from a dryer vent in winter, and they build in the hood, the wall cavity, or right at the exterior flap. We’ve pulled nests from Westmont vents that completely sealed the exhaust – dryers running for 90 minutes on a load that should take 30. After removal, we install a hood with a spring-loaded flap and a screen where code allows, then verify airflow. This isn’t a separate wildlife service; it’s part of what the dryer vent job requires here.

Crawlspace Vent Rerouting
This is the one we find most often on Westmont’s older duplexes. The original dryer vent terminated at a roof jack that failed years ago, someone disconnected the duct, and the dryer has been venting straight into the crawlspace ever since. Lint builds up down there, creating a serious fire hazard. We pull the old duct, run a proper rigid aluminum run to a new exterior termination, and seal the old roof jack permanently. If your dryer vent disappears into the floor, call us.

AfterCommon Dryer Vent Cleaning Problems We See in Westmont Homes
- Dryer vent terminates into the crawlspace. Original roof jack flashing on these 1940s – 50s homes rusts through in as little as 15 years. When it does, the duct often gets pulled apart and left venting lint into the crawlspace, where it accumulates against joists and wiring. This is a fire waiting to happen, and it’s the most common call we answer in Westmont.
- Bird nests blocking the exterior hood. The warm exhaust attracts starlings and pigeons, especially during the winter months when South LA gets its occasional rain. A nest in the hood or wall cavity can completely block airflow and force the dryer’s high-limit thermostat to cycle constantly, which shortens the appliance’s life.
- Plastic flex duct from the original retrofit. Westmont’s older duplexes often still have white plastic transition ducts that sag, kink, and trap lint at every bend. We cut those out and replace them with rigid aluminum or DuraFlex semi-rigid duct that maintains proper airflow and resists lint accumulation.
- Homeowners confusing the chimney and dryer vent. In Westmont, many original masonry chimneys were abandoned decades ago when wall furnaces replaced fireplaces. The dryer vent is a completely separate system, but if the chimney was capped or removed, sometimes the dryer vent was tied into the old flue cavity – a code violation and a fire hazard. We see it often enough that we check for it on every job.
On a recent call in Westmont, our tech found a 1950s stucco duplex with a dryer vent that had been disconnected and was venting directly into the crawlspace – common in these older homes where original roof jack flashing had rusted through. We reconnected the vent using DuraFlex semi-rigid duct, installed a proper termination cap, and cleared a bird nest from the exterior wall cavity that had been blocking airflow for years. That’s a standard Westmont job for us.

FAQs – Dryer Vent Cleaning in Westmont
Because your vent is restricted, and in Westmont it’s usually one of three causes: a bird nest in the exterior hood, a kinked transition duct behind the dryer, or a disconnected duct venting into the crawlspace. All three reduce airflow enough that the dryer can’t evacuate moisture efficiently, so the thermostat cycles too often and clothes stay damp. The fix is a proper cleaning and inspection, not a new dryer. Call (855) 382-6159 and we’ll diagnose it in under an hour.
Every 12 to 18 months for a household of two adults, and every 12 months if you run the dryer more than four loads a week. Westmont’s older homes with retrofitted vents and longer duct runs accumulate lint faster than newer construction with short, straight runs. If you have a plastic flex transition duct or a bird-prone exterior hood, push that interval down to once a year regardless.
Yes. Roof-terminated dryer vents are common in Westmont’s single-story bungalows and low duplexes, and they require a different approach because the duct run is longer and the rooftop termination is harder to access. We use extended rotary brushes and roof-safe access equipment, and we inspect the roof jack flashing while we’re up there. If the flashing has failed, we’ll show you the photos and recommend a repair before it leaks into the wall cavity.
It shouldn’t, but in Westmont it sometimes does. We’ve found older homes where the dryer vent was routed into an abandoned chimney cavity during a past remodel, which is a fire hazard and a code violation. Even if your chimney and dryer vent are separate systems, both share the same roof plane, so a failed chimney flashing can leak water into the same wall cavity the dryer vent runs through. We inspect both when we’re on the roof.
We install rigid aluminum duct, DuraFlex semi-rigid aluminum flex, and proper louvered terminations from Gelco and Olympia Chimney. We don’t use plastic flex duct or foil dryer vent. On the chimney side, when a Westmont job reveals a deteriorated flue, we can resurface it with HeatShield rather than forcing a full liner replacement – an option most dry vent cleaning companies can’t offer.
