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 Sierra Madre
Dryer vent cleaning in Sierra Madre typically runs $180 – $340 for a standard single-family home, and most jobs are completed in under two hours with the dryer back in service the same day. We’re the Dryer Vent Cleaning crew local homeowners call when dry times stretch past one cycle or when that burnt-lint smell shows up in the laundry room.
Our dispatch and scheduling run through the Los Angeles office, but the technicians who serve Sierra Madre know the foothills well. We’ve worked the pre-war bungalows along Sierra Madre Boulevard, the ranch homes tucked above Baldwin Avenue, and the hillside places near Mount Wilson Trail where the canyon winds hit hardest. Roy Castellanos built Hollis Air Duct Cleaning on showing up inside the window, pricing in writing before we touch anything, and leaving the site clean. That’s The Garrison Standard, and it’s how we operate in every Sierra Madre home we enter.

Dryer Vent Cleaning Service in Sierra Madre
Dryer Vent Cleaning Service in Sierra Madre means more than pulling lint from a trap. In this foothill city, it often means addressing decades of accumulation in original galvanized runs, post-Bobcat Fire ash packed into wall chases, and crushed sections hidden under pier-and-beam floors that modern high-CFM dryers were never designed to push against.
A standard Dryer Vent Cleaning Service in Sierra Madre runs $180 – $260 for a single-story home with accessible termination, and $260 – $340 for multi-story runs, buried terminations, or jobs requiring camera inspection and agitation tools. Homes with original 1920s – 1950s ductwork typically land in the upper half of that range because of the extra time needed to navigate fragile galvanized elbows and clear compacted debris.
We use Rotobrush rotary brush systems for mechanical agitation inside the run, paired with Nikro negative-air machines that capture dislodged material under HEPA filtration. This matters in Sierra Madre because the lint-and-ash mix we find here is denser than typical lint alone. A simple blower pass won’t clear it.
When to Schedule Cleaning
Two cycles to dry a load is the clearest signal. So is a hot exterior wall above the dryer, moisture inside the drum after the cycle finishes, or a burnt smell that wasn’t there before. In Sierra Madre’s older homes, we also recommend inspection after any major canyon wind event that could have pulled ash through leaky exterior penetrations.
What the Service Includes
We disconnect the dryer, inspect the full run with a borescope camera when access is limited, mechanically agitate and extract debris, test airflow before and after, and reconnect with proper transition ducting. You’ll see the before-and-after photos. We leave them with you, along with the written invoice and our 365-Day Done Right Promise.
Dryer Vent Installation in Sierra Madre
Dryer Vent Installation in Sierra Madre often turns into detective work. The original 4-inch galvanized run in a 1928 bungalow wasn’t sized for a modern dryer’s airflow, and the wall chase it occupies may be unlined, acting as a secondary trap for wildfire ash and rodent debris. We don’t just replace what’s there. We figure out what should have been there.
New Dryer Vent Installation in Sierra Madre typically runs $340 – $580 for a standard through-wall rigid metal run with proper termination, and $580 – $890 for jobs requiring wall chase lining, rerouting around structural obstacles, or pier-and-beam crawl work. Every installation gets a written price before we cut anything open.
We spec rigid aluminum or galvanized steel per IRC M1502, never the flexible foil or plastic that some handyman specials leave behind. For terminations, we use Guardsman hoods with backdraft dampers where the exposure to canyon wind justifies the upgrade.
Rerouting Around Problem Chases
When an original wall chase is too narrow, unlined, or packed with decades of ash and lint that can’t be fully cleared, we often reroute through a soffit or exterior wall with proper clearances. This costs more upfront than a simple replacement, but it eliminates the hidden reservoir that keeps reclogging the system.
Bird Guard and Termination Upgrades
Sierra Madre’s tree canopy attracts nesting birds and squirrels. A standard flapper termination without screening invites blockages. We install vent caps with integrated guards that meet code without creating lint traps themselves. It’s a small detail that prevents a mid-summer emergency call.
Trusted Brands We Service in Sierra Madre
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation inside damaged or compacted runs, Nikro negative-air machines for contained debris extraction, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. We stock Guardsman termination hoods and backdraft dampers locally, so Sierra Madre customers aren’t waiting on shipping when an installation needs a specific cap. For homeowners with Aprilaire whole-home ventilation systems tied into their laundry rooms, we coordinate dryer vent work with the broader airflow design so the two systems aren’t fighting each other. Every tool on our van is professional-grade, not hardware-store gear, and we explain what we’re using and why before we start.
Common Dryer Vent Cleaning Problems We See in Sierra Madre Homes
- Original galvanized runs packed with Bobcat Fire ash. The 2020 fire left fine gray residue throughout the foothills, and in Sierra Madre’s unlined wall chases, that ash mixed with lint into a dense felt that standard cleaning can’t touch. We find it behind walls along Sierra Madre Boulevard and in the older neighborhoods near Mary’s Market, still accumulating years later.
- Crushed runs under pier-and-beam foundations. Sierra Madre bungalows often have flex duct connections between the dryer and a rigid trunk line running through a crawl space. Foundation movement, pest activity, or a previous owner’s storage crush these connections flat. The dryer works harder, dry times stretch, and the homeowner assumes the appliance is failing.
- Undersized 4-inch runs choking modern dryers. A 1920s home was built for a clothesline or a basic vented dryer moving half the CFM of today’s units. Forcing modern airflow through original galvanized elbows creates back pressure that drives lint into every joint and seam. The vent looks clear from both ends, but the elbows are packed solid.
- Canyon wind infiltration through leaky terminations. Sierra Madre’s proximity to Angeles National Forest means seasonal Santa Ana and canyon winds that pressurize exterior walls. A loose or missing backdraft damper lets wind, pollen, and residual ash into the run, where it mixes with moist exhaust air and hardens against the duct wall.
Pricing for Dryer Vent Cleaning in Sierra Madre, CA
Here’s what Dryer Vent Cleaning costs in Sierra Madre’s market right now:
| Service | Typical Range |
|---|---|
| Standard single-story dryer vent cleaning | $180 – $260 |
| Multi-story or buried termination cleaning | $260 – $340 |
| Camera inspection with agitation cleaning | $280 – $360 |
| New rigid metal vent installation | $340 – $580 |
| Complex reroute or pier-and-beam crawl work | $580 – $890 |
| Bird guard / termination cap replacement | $85 – $160 |
What moves you up or down within these ranges? Accessibility is the big one. A termination on an exterior wall at ground level is straightforward. A run buried in a finished basement ceiling, routed through a second-story soffit, or snaking under a pier-and-beam floor takes more time and specialized tools. The condition of the existing duct matters too. Original galvanized in a 1940s Sierra Madre bungalow is more fragile than a 1990s aluminum run and requires slower, more careful work.

FAQs About Dryer Vent Cleaning in Sierra Madre
Sierra Madre’s combination of older, undersized galvanized ductwork and residual wildfire ash creates a denser, stickier lint deposit than the newer aluminum runs common in Pasadena’s post-1960s housing stock. The canyon winds and inversion layers here also push more exterior particulate through leaky terminations. Call (361) 326-5060 and we’ll camera-inspect to show you exactly what’s inside your run.
Yes. We use borescope cameras to inspect runs inside wall chases without cutting drywall, and we do this routinely in Sierra Madre’s pre-1950s homes where the original galvanized is hidden from both ends. If the camera shows crush damage or packed ash that can’t be cleared, we’ll write a price for accessible repair or rerouting before any demolition. Call (361) 326-5060 to schedule.
Two cycles almost always indicates restricted airflow, not appliance failure. We test airflow at the termination with a calibrated manometer; if it’s below 1,500 FPM for a standard residential dryer, the vent is the culprit. In Sierra Madre, we most often find crushed flex connections under pier-and-beam floors or packed elbows in original galvanized runs. Call (361) 326-5060 for a free airflow test.
We find it in both, but the dryer vent discovery surprises more homeowners. Ash enters through leaky exterior terminations and mixes with moist lint exhaust, forming a gray-brown felt that standard cleaning misses. In Sierra Madre’s unlined wall chases, this material can accumulate for years after the fire itself. Our Rotobrush agitation and negative-air extraction is specifically designed to remove it. Call (361) 326-5060 if you smell residual smoke in your laundry area.
We disconnect the dryer, access the crawl space, remove the damaged flex or crushed rigid section, and replace with proper rigid metal duct sealed at every joint. We test airflow before we close up, and we photo-document the work. Typical cost for pier-and-beam replacement runs $450 – $720 depending on crawl accessibility and run length. Call (361) 326-5060 for a written estimate.
