Why Hollis Air Duct Cleaning Is Sunnyvale’s Preferred Dryer Vent Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our reputation in Sunnyvale is built on showing up when we said we would and pricing in writing before we touch anything.

Dryer Vent Repair in Sunnyvale
Dryer Vent Repair in Sunnyvale addresses the crushed, disconnected, or improperly routed vent runs we find in nearly every mid-century home we service. The job involves inspecting the full vent path with a camera, replacing damaged sections with rigid metal ducting, sealing joints with proper fasteners and mastic, and verifying airflow at the termination cap. Most Sunnyvale homeowners need this when their dryer starts overheating, when they find lint collecting behind the machine, or when a home inspection flags the vent before a sale. A typical Dryer Vent Repair in Sunnyvale runs $180 – $420 depending on how much of the run needs replacement and whether we need to access an interior wall cavity or slab-embedded section.
Crushed Flex Vent Replacement
The flexible foil transition hose behind your dryer was never meant to last decades. We pull the unit, remove the crushed or kinked flex, and install a proper rigid metal connection that won’t collapse again. This alone often restores full airflow and cuts drying time by half.
Slab-Vent Rerouting
When an original vent runs through the concrete slab and has cracked or packed with lint at a low point, we design a new overhead route using rigid metal and proper slope. It’s more work than a simple cleaning, but it eliminates the hidden fire risk that camera inspections keep revealing in Eichler and ranch homes near El Camino Real.
Dryer Vent Cleaning Company in Sunnyvale
Dryer Vent Cleaning Company service in Sunnyvale means more than blowing air through a hose. We use rotary brush systems from Rotobrush and negative-air extraction from Nikro to agitate and remove lint buildup from the full vent path, including elbows and termination points that hand tools miss. A Sunnyvale homeowner should schedule this annually if they run the dryer more than four times weekly, bi-annually if they have pets that shed, or immediately if drying times have increased or the exterior vent flap isn’t opening during cycles. A standard Dryer Vent Cleaning Company visit in Sunnyvale runs $150 – $280; homes with second-story laundry rooms or long horizontal runs through slab or wall cavities fall toward the higher end.
Camera Inspection and Documentation
We run a borescope through the vent before and after cleaning so you see what was in there. In Sunnyvale’s older homes, we regularly find construction debris from 1960s builds, bird nests in low-mounted caps, and lint packed at slab elbows that the homeowner never knew existed.
Termination Cap Service
The exterior cap is where the work proves itself. We verify the flapper opens fully under dryer pressure, clear any paint or landscaping blockage, and install a bird guard if the cap is accessible to nesting animals. A stuck cap turns your vent into a lint trap inside the wall.
Trusted Brands We Service in Sunnyvale
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for contained extraction, and filtration and sealing products from Guardsman and Abatement Technologies. We don’t show up with hardware-store vacuums and a prayer. For Sunnyvale customers, this means we stock the rigid metal fittings, proper termination caps, and bird guards that match your home’s original construction without waiting on special orders. When we find a crushed run or failed cap during a cleaning, we can usually repair it same visit because the truck carries what the local housing stock actually needs.
Common Dryer Vent Cleaning Problems We See in Sunnyvale Homes
- Crushed foil flex behind the dryer in Heritage District ranches. The original flexible transition hose has been compressed against the wall for twenty years, creating a lint-packed choke point that reduces airflow and forces the dryer to overheat. We replace it with rigid metal every time.
- Lint accumulation at slab-embedded elbows in Eichler homes. The low point of a vent run beneath the concrete floor collects moisture and lint into a dense, hazardous mat. Camera inspection is the only way to find it, and rotary agitation under negative pressure is the only way to remove it safely.
- Termination caps painted shut or buried under ivy near Fremont Avenue properties. Sunnyvale’s mature landscaping and exterior painting cycles often seal the vent exit completely, causing lint to back up into the wall cavity where it compounds the fire risk and can damage interior drywall.
- Disconnected joints inside wall cavities from seismic settling. Decades of minor earthquake movement loosen lapped joints in original metal ducting, especially in homes near the Calaveras Fault zone. Hot, moist air leaks into the wall, promoting dry rot and mold that shows up as a musty smell near the laundry closet.

FAQs About Dryer Vent Cleaning in Sunnyvale
Slab-on-grade construction creates longer vent runs with low points where lint settles, and the original rigid metal ducting often has lapped joints that trap debris. In neighboring cities with raised foundations, vents are shorter, straighter, and easier to clean completely. Call (361) 326-5060 for a camera inspection to see what’s actually in your run.
We use a rotary brush system from Rotobrush combined with Nikro negative-air extraction to agitate and remove lint without dislodging the duct. For severe blockages or cracked slab sections, we may recommend rerouting the vent overhead to eliminate the hidden low point entirely. Call (361) 326-5060 and we’ll inspect it first, price it in writing, then do the work.
Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for contained lint extraction, and sealing products from Guardsman and Abatement Technologies for repairs. These are the same tools commercial crews use, not hardware-store gear, and we explain what each one does on every job. Call (361) 326-5060 to ask questions about our process before booking.
Annually for most households, every six months if you have shedding pets or run more than four loads weekly. Sunnyvale’s dry summers and damp winters create a cycle where lint absorbs moisture, compacts, and then bakes hard during the first hot spell, making annual service more important here than in consistently dry climates. Call (361) 326-5060 to set up a recurring schedule.
