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.

AfterFast, Reliable Dryer Vent Cleaning Across Boulder
Dryer vent cleaning in Boulder typically runs $150 – $275 for a standard single-family home, with most jobs completed in 60 – 90 minutes. We dispatch crews from our Denver office and routinely serve Boulder neighborhoods from Mapleton Hill to North Boulder, usually booking within a few days of your call.
We’ve been in homes along Baseline Road where the dryer’s lint trap looked clean but the vent line was packed solid with compacted debris from years of Front Range dust mixing with laundry lint. That’s the thing about Boulder: the same semi-arid climate that draws people here sends fine particles through every opening in a house, and your dryer vent is no exception. When a vent line clogs, the dryer works harder, runs hotter, and becomes a genuine fire hazard. In older Boulder homes near Chautauqua or the University Hill area, we’ve found original flexible ductwork from the 1960s and 1970s that’s cracked and sagging, creating traps where lint accumulates out of sight. Our Dryer Vent Cleaning crews bring rotary brush systems and negative-air machines to pull that debris out completely, not just push it around.

Why Hollis Air Duct Cleaning Is Boulder’s Preferred Dryer Vent Cleaning Company
Hollis has built its reputation in Boulder the same way we have everywhere: by showing up inside the quoted window, pricing the job in writing before touching anything, and leaving the site clean. Roy Castellanos and the team here operate under The Garrison Standard, which means no moving targets and no surprises at the door.
Our technicians are background-checked and uniformed. You’ll know who’s arriving before they pull up. And when you call (361) 326-5060, a live person answers, 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday morning to get on the schedule.
We know Boulder’s housing stock. The mid-century ranches in Table Mesa, the converted bungalows near Pearl Street, the newer builds in North Boulder, each presents different vent configurations and different wear patterns. That local knowledge matters when we’re routing a rotary brush through a 50-year-old galvanized line versus a modern smooth-wall aluminum run. We also handle Duct Sealing in Boulder and Air Duct Cleaning in Boulder for homeowners who want their full system addressed.
Dryer Vent Repair in Boulder
Dryer Vent Repair in Boulder addresses the physical damage that cleaning alone won’t fix: crushed or disconnected transition ducts, corroded vent caps, improper routing that creates moisture traps, and joints that have separated due to vibration or age. In Boulder’s older neighborhoods, we regularly find galvanized steel venting that’s rusted through from decades of moisture cycling, especially in homes where the dryer sits in a basement or utility closet with poor airflow. Repair work in Boulder typically ranges from $120 – $350 depending on material length and accessibility, with full reroutes running $400 – $650 when we need to establish a new path to exterior wall termination.
When Repair Beats Replacement
A short section of damaged flexible transition duct behind the dryer, a cracked vent cap on the exterior wall, or a single separated joint, these are straightforward fixes that restore safe airflow without rebuilding the whole line. We’ll show you the damage before quoting, and the price is written down before we start.
Rerouting for Safety and Efficiency
Some Boulder homes, especially those with additions or finished basements, have dryer vents that run too far, turn too many times, or terminate in crawl spaces instead of outside. We reroute these to meet manufacturer guidelines: rigid metal ducting, minimal bends, and direct exterior termination.
Dryer Vent Cleaning Company in Boulder
Dryer Vent Cleaning Company in Boulder describes what Hollis delivers: a scheduled, thorough cleaning of the entire vent path from dryer back to exterior cap, using professional-grade equipment that removes lint and debris residential vacuums cannot touch. Our crews use Rotobrush rotary brush systems to mechanically scrub the duct walls, paired with Nikro negative-air machines that pull dislodged material out of your home rather than redistributing it. For Boulder homeowners, this matters particularly during wildfire season when fine ash particles already stress indoor air quality, a clean dryer vent removes one more source of particulate circulation and fire risk. Standard cleaning runs $150 – $275; homes with second-story laundry rooms, roof terminations, or long horizontal runs may edge toward $300 – $375.
What the Process Looks Like
We inspect the full line first with a camera when access allows, then agitate and extract debris with rotary brushes sized to your duct diameter. The dryer itself gets attention too: we clean the lint trap housing, blower wheel, and internal ducting that feeds the vent line.
Bird Guard and Cap Upgrades
Boulder’s foothill location means birds, squirrels, and rodents investigate vent openings year-round. We install metal bird guards and replace deteriorated plastic caps with durable hardware that vents properly while keeping wildlife out.
Trusted Brands We Service in Boulder
We stock parts and accessories from Honeywell, Aprilaire, and Abatement Technologies to complete most Boulder jobs without ordering delays. That means when your vent cap is cracked or your transition duct needs replacement, we’re not making a second trip. Our Nikro negative-air equipment and Rotobrush rotary systems are the same tools commercial duct crews use in hospitals and schools, sized appropriately for residential dryer vent lines. For Boulder customers, this translates to faster turnaround and repairs that hold up. We don’t guess at compatibility; we match components to your existing system and test airflow before leaving.
Common Dryer Vent Cleaning Problems We See in Boulder Homes
- Compacted lint mixed with Front Range dust. Boulder’s semi-arid climate generates fine dust that combines with laundry lint into a dense, almost felt-like layer inside vent walls. This buildup restricts airflow more severely than lint alone and requires rotary brush agitation to remove completely.
- Original flexible ductwork in pre-1980 homes. The ribbed plastic or foil flex lines common in Boulder’s older housing stock sag between supports, creating low points where lint accumulates. These materials also deteriorate with heat cycling and become fire hazards themselves.
- Swamp cooler proximity causing moisture corrosion. Homes with both swamp coolers and dryers in shared utility spaces sometimes see accelerated rust on metal vent components. The humidity from cooler operation contrasts sharply with Boulder’s dry climate, and that cycling corrodes galvanized steel faster than in consistently dry or consistently humid regions.
- Improper terminations in finished basements. Boulder basement remodels sometimes left dryer vents exhausting into crawl spaces or through walls without proper caps. This pumps moisture and lint into structural cavities, creating mold risks and fire hazards hidden from view.
