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 Alamo
Dryer vent cleaning in Alamo typically costs $145 – $295 for a standard single-system home, with larger estate properties running $250 – $450 depending on run length and access. That’s the honest range you should expect before anyone steps through your door. Our crews work throughout Alamo regularly, from the gated estates off Stone Valley Road to the custom builds along Danville Boulevard. We know these homes, we know these attics, and we know what a 35-foot vent run through a 140-degree attic does to flex duct over 30 years. Call (980) 447-2498 and we’ll get you a written price before any work begins.
Why Linden Air Duct Cleaning Is Alamo’s Preferred Dryer Vent Cleaning Company
Alamo homes are different. A 5,200-square-foot custom build with three air handlers and a laundry room on the far side of the house presents a vent cleaning job that has nothing in common with a 1,400-square-foot condo in Walnut Creek. Our technicians have spent years working Alamo attics, and they understand the failure patterns specific to this housing stock: original flex duct from the 1980s and 1990s, long horizontal runs, and mechanical chases shared with second or third HVAC systems. You’ll know exactly who is coming before anyone arrives. We send the tech’s name and photo in advance, and they show a photo ID badge at the door. Every technician is background-checked and identity-verified under The Threshold Standard, the verification protocol we’ve operated under since 2004 as part of the Threshold Group family.
Our reputation in Alamo is built on one simple promise: the price we quote in writing is the price you pay. No surprise invoices after the fact. And if a repair we make doesn’t hold, we come back at no charge under our 365-Day Done Right Promise. Those aren’t marketing phrases. They’re written commitments on every job we do in Alamo.
Dryer Vent Inspection in Alamo
A dryer vent inspection in Alamo is a diagnostic service that tells you exactly what’s happening inside a vent run you cannot see, and it costs between $95 and $145 depending on run length and whether camera work is needed. Given the length and complexity of vent runs in Alamo’s larger estate homes, inspections here routinely uncover problems that a simple visual check at the appliance connection would miss entirely. We use camera inspection tools to map the full run from the dryer to the exterior termination point, checking for lint plugs, sagging flex duct, kinked sections, and improper vent cap function. When a customer mentions a faint burnt-lint smell or clothes that need two full cycles to dry, that’s a sign to bring the camera.
Camera Inspections in a Long-Run Environment
Alamo’s vent runs are often 25 to 40 feet and pass through unconditioned attic space. A camera inspection is the only way to see what’s happening at the midpoint of that run. We recently inspected a home off Stone Valley Road where the exterior termination cap looked clean, but the camera found a dense lint plug about 22 feet in, right where the original 1990s flex duct had sagged across the attic floor. That’s the difference between thinking your vent is fine and knowing it’s a fire hazard.
Visual Component Check
Beyond the ductwork itself, an inspection covers the termination cap, the lint trap bypass, and the condition of the vent material. In Alamo’s 130 – 140°F summer attics, plastic vent runs are particularly prone to failure. We check for the right materials, proper termination clearances, and airflow at the end of the run so you know the whole system works, not just the part connected to your dryer.
Commercial Dryer Vent Cleaning in Alamo
Commercial dryer vent cleaning in Alamo covers larger multi-unit properties, community laundry facilities, and properties like wineries or estate clubhouses with shared laundry equipment, and it typically runs $350 – $750 depending on system complexity and run count. These jobs need a different approach than a single-family home because the equipment cycles far more frequently and the vent runs often serve multiple dryers through a shared trunk line. We schedule commercial work in Alamo with minimal disruption, which matters when you’re operating a business or managing a community facility that cannot afford downtime.
Multi-Unit and Shared-Laundry Systems
Shared laundry rooms in HOA clubhouses or estate guest houses accumulate lint at an accelerated rate because multiple households use the same dryers. A commercial job usually means running agitation tools through the full trunk line under negative pressure with HEPA filtration at the vacuum, not just cleaning the first few feet of visible ductwork. We document the entire process with before-and-after photos so a property manager or HOA board has records of the work.
Documentation for Property Managers
In Alamo, where many large properties are managed by third parties or family offices, we provide written documentation of every commercial job: the run length measured, the condition of the ducting, airflow readings at the termination point, and photos of any lint removed. If a property has multiple dryers or multiple vent runs, each one gets its own line on the report. That record is what separates a real cleaning from a low-effort visual check, and it’s why property managers keep us on contract.
Trusted Brands We Service in Alamo
Alamo’s estate homes run the full spectrum of dryer makes and vent configurations, and we service them all. Our crews work with professional-grade cleaning equipment from Rotobrush, the same agitation and negative-pressure systems used in commercial duct work, not the small portable units a homeowner might rent. We also carry air-quality products from Guardsman and Aprilaire for Alamo customers who want to address what happens after the vent is clean: the air moving through the laundry room and the rest of the house. When we identify a failed component, we can often complete the repair same-visit because our trucks stock common replacement parts for the vent systems found in Alamo’s era of housing: 1980s and 1990s flex duct, termination caps, and bird guards.
Common Dryer Vent Cleaning Problems We See in Alamo Homes
- Collapsed flex duct from extreme attic heat. Original flex duct installed in the 1980s and 1990s has spent 30 to 50 years baking in Alamo’s summer attics, which regularly hit 130 – 140°F. The material kinks or collapses, creating a spot where lint catches and accumulates until the run is nearly blocked.
- Vent runs that share a mechanical chase with a second air handler. In multi-air-handler estate homes, the dryer’s lint pathway often runs through the same unconditioned space as a second or third HVAC system. That shared chase holds heat and traps the lint the dryer pushes through, accelerating buildup at the midpoint of the run rather than at the connection point.
- Ash and particulate intrusion during Diablo wind events. Fall Diablo winds sweep fine particulate from East Bay grassland and oak-woodland fires directly into Alamo attics through gable and soffit vents, adding a layer of ash to dryer vent lint loads. The same run that was clean in July can show measurable particulate accumulation by October, even in a household that does little laundry.
- Long runs far beyond the 15-foot manufacturer-recommended maximum. A single dryer vent run in Alamo can sit 25 to 40 feet from the appliance, far longer than the short, straight runs typical in Walnut Creek or Danville tract homes. Dryers are not engineered for that distance. Lint loses velocity and settles mid-run, which is why Alamo vents need cleaning roughly twice as often as nearby shorter-run homes.

FAQs About Dryer Vent Cleaning in Alamo
Your Alamo dryer is likely pushing air through a vent run that is 25 to 40 feet long, far exceeding the 15-foot maximum that most dryer manufacturers specify, and that run has been baking in a 130 – 140°F attic for decades. The combination of extreme length and extreme heat causes lint to settle mid-run instead of exiting the termination cap, and over time that becomes a dense plug that chokes airflow. The dryer still heats, but the moisture has nowhere to go. The fix starts with an inspection to locate the blockage, then a full cleaning to clear it. Call (980) 447-2498 and we’ll find the plug.
An Alamo estate home should have its dryer vent cleaned every 12 months, and in some cases every 6 months, while a smaller Walnut Creek home with a short, straight vent run can often go 18 to 24 months between cleanings. The difference is run length and attic heat: Alamo’s 25-to-40-foot runs through 140-degree attics cause lint to settle and accumulate at roughly twice the rate of a 10-foot run in a conditioned crawl space. Add fall Diablo wind ash intrusion, and the interval shortens further.
Yes, and the reason is the mechanical layout. Alamo’s 3,500 – 7,000+ square foot estate homes were built with two or three separate air handlers, often in different attics, and the dryer vent’s lint pathway frequently shares a mechanical chase with a second or third HVAC system. Cleaning only the visible laundry-room connection misses the bulk of the buildup for these homes. We map the full run, clean under negative pressure with agitation tools suited to long runs, and verify airflow at the exterior termination, not just at the appliance connection. The process is the same name, but the scope is entirely different.
Yes, dryer vent fires can happen in newer Alamo homes too. The fire risk comes from lint accumulation and restricted airflow, which are functions of vent run length and heat exposure, not the home’s construction year. A 2005-built estate home with a 35-foot vent run through an unconditioned attic is at higher risk than a 1970s home with a short, straight run. Lint is combustible, period. When airflow slows, the dryer runs hotter, and a hot dryer pushing into a plugged vent is the fire scenario. Clean the vent annually and the risk drops dramatically.
Yes, we offer commercial dryer vent cleaning for Alamo properties including wineries, HOA clubhouses, estate guest facilities, and multi-unit laundry rooms, typically in the $350 – $750 range for full system cleaning.
