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.

Air duct cleaning in Saranap, CA typically runs $450 – $750 for a whole-home system, with dryer vent cleaning adding $120 – $180 and duct sealing ranging $800 – $1,400 depending on access and condition. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we’ve built our work around the realities of Saranap’s fog-belt climate and mid-century housing stock. Call us at (361) 326-5060 for a written estimate before any work starts.
Why Saranap Homes Are Different
Saranap sits in a low-lying pocket of Contra Costa County where roofs and attics stay cool and damp through the summer fog belt, so duct systems here are far more prone to condensation drip, mildew, and musty odors than the dry, hot ductwork found in neighboring Walnut Creek or Danville. Most homes are mid-century single-story ranch builds from the 1950s through the 1970s, with low-pitch attics and original or first-replacement flex-duct runs laid directly over attic insulation. That combination traps moisture against the duct surface.
Our technicians working Saranap’s older ranch attics regularly find duct runs sagging between joists with standing condensation water in the low spots. It’s a fog-belt pattern we rarely see in hotter inland East Bay cities. The cool, fog-influenced summers and mild, wet winters keep attic temperatures moderate but humidity persistently high, so ducts here rarely dry out fully. Condensation-related microbial growth is a recurring problem rather than a heat-driven one, which changes how we approach both cleaning and sealing work.
Our Main Saranap Services
Saranap homeowners call us most often for these three jobs, each shaped by the local climate and housing stock.
Air Duct Cleaning in Saranap
We clean supply and return ductwork with a rotary brush system and negative-air machine to dislodge and extract buildup. In Saranap, that buildup is often damp and compacted from years of fog-belt humidity, so we allow extra time for thorough drying inspection. We also check for sagging low spots where water pools. Every job gets a written price before we start and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in Saranap details our full process.
Dryer Vent Cleaning in Saranap
Dryer vents in Saranap’s older ranch homes often run through low attics or short exterior walls with minimal slope, and the same damp conditions that affect ducts can cause lint to cling and compact. We use a rotary brush and high-velocity vacuum to clear the full run, then verify airflow at the exterior cap. Blocked dryer vents are a genuine fire hazard, and we treat them with the same written-price discipline as any other job. Dryer Vent Cleaning in Saranap covers what to expect.
Duct Sealing in Saranap
Saranap’s flex-duct systems, especially those sagging with moisture weight, develop leaks at seams and connections that bleed heated or cooled air into the attic. We seal accessible ductwork with mastic and reinforced tape, then pressure-test to confirm results. In fog-belt attics, sealing also reduces the humid outside air drawn into the system, which helps control the condensation cycle. Duct Sealing in Saranap explains our approach.
