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 Claremont
Dryer vent cleaning in Claremont typically runs $150 – $280 for a standard single-family home, and most jobs are completed in under two hours. If your dryer takes longer than one cycle to dry towels, or the laundry room feels unusually warm during operation, you’re likely dealing with a blocked vent that needs immediate attention.
We serve Claremont from our Los Angeles office, with crews running daily routes through College Heights, Old Claremont, and the north-side neighborhoods near the colleges. We know the difference between a 1970s tract home off Foothill Boulevard and a 1920s bungalow on Harvard Avenue, and we know what hides inside those walls before we arrive. Our technicians are background-checked, uniformed, and equipped with Rotobrush rotary systems and Nikro negative-air machines, the same tools commercial crews use. When you call (361) 326-5060, a live person answers, 24 hours a day.
Why Hollis Air Duct Cleaning Is Claremont’s Preferred Dryer Vent Cleaning Company
Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004. We’ve built our reputation in Claremont on showing up inside the quoted window, pricing the job in writing before touching anything, and leaving the site clean. That’s The Garrison Standard, and it applies to every job we run in the 91711 ZIP code.
Our Claremont customers aren’t looking for the cheapest coupon in the mail. They’re looking for a crew that won’t track dust through a restored Craftsman kitchen or claim a $79 special that balloons to $400 once the van is in the driveway. We give one flat price per system, agreed before work starts. No per-vent add-ons. No surprises at the door.
Roy Castellanos leads our operations, and every Hollis technician follows The Garrison Code: arrive prepared, explain what you found, fix what you said you’d fix, and stand behind it for a full year. Our 365-Day Done Right Promise means if the work fails within twelve months, we return and make it right at no charge, including a free second visit.
Dryer Vent Cleaning Service in Claremont
Dryer Vent Cleaning Service in Claremont is not a simple vacuum job, not in this city. The typical cleaning runs $150 – $220 for a straight run with accessible termination, and $220 – $280 when we find crushed or disconnected ductwork behind original lath-and-plaster walls. We start with a camera inspection from the outside termination, then use agitation tools under negative pressure with HEPA filtration to clear the full run, not just the first few feet from the dryer.
Claremont’s housing stock works against easy cleaning. Many homes in College Heights and Old Claremont started with 1920s – 40s gravity furnaces later converted to forced-air. The original sheet-metal ducts were rarely resized or sealed. Our techs regularly find disconnected runs and dust buildup that a simple vacuuming won’t fix. Fine alluvial silt from the San Gabriel wash pushes through poorly sealed return ducts and migrates into the lint pathway. It looks like lint, but it behaves differently, and a crew that only cleans from the dryer side misses the real blockage.
Camera Inspection and Full-Run Clearing
We run a borescope from the outside termination before we touch anything. This shows us crushed sections, bird nests, and the silt-lint mixture that chokes Claremont vents. Our Rotobrush system breaks loose packed material while Nikro negative-air machines pull it out under containment. We show you the before-and-after images.
Reconnection and Sealing Behind Walls
When we find disconnected ductwork in a College Heights wall cavity, we don’t patch around it. We open the access, reconnect the run with proper fittings, and seal the joint at the blower motor cabinet. This is where the real fix happens. The price is written before we cut access, not after.
Dryer Vent Installation in Claremont
Dryer Vent Installation in Claremont costs $280 – $450 for a standard through-wall run with metal ducting and proper termination cap, and $450 – $650 when we’re routing through finished spaces, replacing asbestos-wrapped material, or installing bird guard protection. We use solid metal ducting, not the flexible foil or plastic that most hardware stores sell, because the California Building Code and common sense both demand it.
New installation makes sense when your current vent is plastic or foil, when the run exceeds 25 feet without proper boost, or when the termination exits under a deck or into a garage. In Claremont’s older neighborhoods, we also see installations where the original vent was never properly routed to the exterior, instead dumping moist air into crawlspaces or wall cavities. That’s a mold risk and a fire hazard.
Metal Ducting and Code-Compliant Routing
We install 4-inch rigid or semi-rigid metal ducting with sealed joints and proper slope for condensation drainage. Every termination gets a backdraft damper and, where needed, a bird guard. We pull permits when the city requires them, and we know Claremont’s inspection schedule.
Bird Guard and Termination Cap Upgrades
Claremont’s mature tree canopy attracts nesting birds. A standard termination cap without screening invites blockages. We install Guardsman-compatible bird guards that stop nesting without restricting airflow, and we include them in the written price upfront.
Trusted Brands We Service in Claremont
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for contained extraction, and HEPA filtration from Abatement Technologies. We stock replacement termination caps, bird guards, and metal duct fittings locally, so Claremont customers aren’t waiting on parts from a warehouse two counties away. When we find a failed component during a cleaning, we can usually replace it same visit. The brands matter because they determine whether the job gets done in one trip or two, and whether your laundry room stays clean while we work.
Common Dryer Vent Cleaning Problems We See in Claremont Homes
- Crushed runs behind original lath-and-plaster. In Old Claremont, 4-inch metal ducts were often routed through wall cavities never designed for forced-air. Decades of settling, renovation, and gravity have crushed sections flat. The dryer still runs, but airflow is restricted to a trickle. We find these with the camera, not by guessing.
- Alluvial silt masquerading as lint. Claremont’s position at the base of the San Gabriel Mountains means fine dust from the wash enters through poorly sealed returns and migrates into dryer vent runs. It packs tight and doesn’t brush loose the way ordinary lint does. Our negative-air system with HEPA containment is built for this.
- Disconnected ducts at the air handler junction. When gravity furnaces were converted to forced-air, the sheet-metal connection to the blower cabinet was often sealed with tape that failed decades ago. Silt enters here, travels the full run, and chokes the vent from the wrong end. Cleaning from the dryer side alone never fixes it.
- Asbestos-wrapped ducts in pre-1950 homes. Some College Heights properties still have original ductwork wrapped in friable asbestos insulation. Standard agitation tools disturb this material and create a contamination hazard. We identify the wrap before we touch it, follow NADCA protocols, and advise on proper abatement when needed.

FAQs About Dryer Vent Cleaning in Claremont
Old Claremont homes built before 1950 have original sheet-metal ductwork that was never resized or properly sealed when gravity furnaces were converted to forced-air. Disconnected returns near the air handler pull in alluvial silt from the San Gabriel wash, which migrates into the dryer vent pathway and packs tight with lint. Newer homes with modern duct sealing don’t have this dual-entry problem. Call (361) 326-5060 for a camera inspection and exact quote.
We stop, show you the camera footage, and give you a written price for reconnection or replacement before cutting any access. For crushed runs behind lath-and-plaster in College Heights, we open minimal access, replace the damaged section with proper metal ducting, seal all joints, and restore the wall surface. The 365-Day Done Right Promise covers our repair work for a full year. Call (361) 326-5060 to schedule.
Yes. Alluvial silt from the San Gabriel wash is mineral-based, extremely fine, and packs into a dense, felt-like mat when combined with lint. It doesn’t respond to standard brushing or shop-vac suction. Our Nikro negative-air machines with HEPA filtration are specifically designed to extract this material under containment. Pet dander and pollen are lighter and easier to remove; alluvial silt is the hidden problem in Claremont’s older homes. Call (361) 326-5060 for an inspection.
We identify asbestos-wrap during our initial visual and camera inspection, then stop mechanical agitation immediately. Our technicians follow NADCA protocols for containment and advise on licensed abatement when the wrap is friable. We do not disturb asbestos material with standard cleaning tools. If your home was built before 1950 in College Heights or Old Claremont, mention this when you call (361) 326-5060 so we arrive prepared.
In Claremont’s converted gravity-furnace homes, the air handler and dryer vent often share poorly sealed wall cavities or basement joist spaces. When the return duct disconnects at the blower cabinet, negative pressure pulls alluvial silt into the cavity, where it migrates toward the dryer vent pathway. You can clean the dryer vent repeatedly and never fix the real source. We inspect both ends of the system and seal the return connection as part of the complete repair. Call (361) 326-5060 for a full-system evaluation.
