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 Hillsborough
Dryer vent cleaning in Hillsborough typically runs $180 – $340 for a standard single-vent system, and most jobs are completed in under two hours with the home’s laundry routine back to normal the same day. We’re Hollis Air Duct Cleaning, and our crews serve Hillsborough from our San Francisco Bay Area dispatch office.

We know Hillsborough’s housing stock: the 1920s estates with original galvanized runs, the 1960s wings with flex-duct retrofits through cold crawlspaces, the newer additions with rigid ducting that still tie into aging infrastructure. This local knowledge saves time and prevents the missed blockages that happen when a tech treats every job like a standard suburban ranch.
Dryer Vent Installation in Hillsborough
Dryer Vent Installation in Hillsborough is often necessary when an older estate’s original vent run no longer meets current safety codes, or when a homeowner relocates the laundry room during a remodel and needs a new pathway to the exterior. A typical installation in Hillsborough runs $450 – $850 depending on the path length, wall construction, and whether we’re routing through a finished interior or an accessible attic or crawlspace. Homes here are large, walls are thick, and the shortest distance to daylight is rarely a straight line through a standard stud bay.
Code-Compliant Routing Through Older Construction
Many Hillsborough estates have masonry or double-stud walls that complicate vent penetration. We use camera inspection and borescope mapping before cutting to avoid structural members, plumbing stacks, and electrical runs. The Garrison Standard requires us to show the homeowner the proposed path and the written price before any wall is opened.
Rigid Ducting and Proper Slope for Long Runs
When a dryer must vent through an attic or crawlspace to reach an exterior wall, we install rigid metal ducting with proper slope toward the termination point. Flex duct sags and traps lint; rigid duct doesn’t. In Hillsborough’s older homes with 20-foot-plus runs, this detail alone prevents the low-point blockages we find on service calls.
Dryer Vent Repair in Hillsborough
Dryer Vent Repair in Hillsborough addresses the specific failure modes of large, aging homes: corroded galvanized joints, crushed flex duct in tight crawlspaces, and vent hoods damaged by falling oak branches or eucalyptus bark. A typical repair runs $220 – $480, though complex jobs involving wall-cavity access or joint replacement in long runs can reach $650. We always inspect the full length with a camera before quoting, so the price you see is the price you pay.
Corroded Mid-Century Joints and Wall Cavity Lint
Original galvanized runs in Hillsborough’s older wings corrode at the seams, letting lint escape into wall cavities where it becomes a hidden fire load. We locate these separations with camera inspection, remove the compromised section, and replace with rigid duct sealed with mastic, not tape. The homeowner sees the before-and-after footage.
Crushed or Disconnected Flex in Retrofit Runs
Flex duct installed during 1970s and 1980s remodels often gets crushed by storage items in attics or separated at couplings due to thermal cycling. We find these failures by running a camera the full length of the chase, not just checking airflow at the wall. A vent can seem clear at the termination while the actual blockage sits 20 feet away in a cold attic.
Trusted Brands We Service in Hillsborough
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation of compacted lint and debris, Nikro negative-air machines for source-controlled extraction, and filtration products from Honeywell, Aprilaire, and Guardsman. We stock common vent hoods, bird guards, and rigid duct fittings so Hillsborough jobs aren’t delayed waiting for parts. When a Guardsman vent hood on a Hayne Road estate needs replacement after a branch strike, we typically have the matching component on the van.
Common Dryer Vent Cleaning Problems We See in Hillsborough Homes
- Eucalyptus and oak debris packed against vent terminations. Hillsborough’s wooded lots shed bark and leaves year-round, and the first fall storm dumps concentrated debris against vent hoods. This material compacts with lint into a dense mat that simple suction won’t remove; it requires rotary agitation under negative pressure.
- Long flex-duct runs sagging in cold attics and crawlspaces. Retrofit installations through unconditioned spaces develop low points where lint collects over years. The dryer still runs, but drying times creep from 45 minutes to two cycles, and the blower motor overheats.
- Corroded galvanized joints in original mid-century ducting. Hillsborough estates built in the 1950s and 1960s often have original vent runs that have separated at joints, blowing lint into wall cavities. Homeowners smell mustiness but can’t locate the source until camera inspection reveals the breach.
- Post-storm musty air backing into laundry rooms. After heavy rain, blocked vent hoods force warm, damp exhaust air backward through the dryer drum and into the room. Hillsborough homeowners often mistake this for a plumbing or mold issue when it’s simply a vent that can’t breathe.

FAQs About Dryer Vent Cleaning in Hillsborough
Hillsborough’s dense tree canopy of mature oaks, redwoods, and eucalyptus produces leaf litter, bark strips, and pollen that accumulate at vent terminations and inside hoods, combining with laundry lint into blockages that denser, less wooded towns rarely see. The hilly terrain and large lots also mean longer vent runs with more joints and sag points. Call (361) 326-5060 if your drying times have increased; we’ll inspect the full run and give you a written price before any work starts.
We run a camera inspection the full length of the duct chase, from the dryer connection to the exterior termination, so we see crushed flex, disconnected joints, or lint buildup at low points that airflow tests miss. This takes 15 – 20 minutes and lets us show the homeowner exactly what we’re quoting. Call (361) 326-5060 to schedule a camera inspection; estimates are free.
Yes. We route rigid duct through attics, crawlspaces, or soffits to reach a gable end or roof termination, following IRC code limits on run length and number of elbows. A typical through-attic installation in Hillsborough runs $650 – $850 due to the larger home sizes and finished spaces we navigate. We’ll map the path with a borescope and give you a written price before cutting any wall or ceiling.
It’s often a blocked vent hood forcing damp exhaust air backward into the room, especially after fall storms pack debris against the termination. We verify this by checking airflow at the hood and running a camera inspection; if the vent is clear, we’ll tell you it’s time to call a plumber or mold specialist instead. Call (361) 326-5060 and we’ll diagnose it properly.
Most Hillsborough estates need dryer vent cleaning every 12 – 18 months due to the combined lint and tree-debris load; homes with heavy laundry use or multiple dryers may need annual service. After major wildfire seasons or significant fall storms, an inspection is worth scheduling even if drying times haven’t changed yet. Call (361) 326-5060 to set up a maintenance schedule that fits your property.
