Air Duct Cleaning Company in Alamo, CA
Air duct repair in Alamo usually means fixing what decades of East Bay dust, Diablo wind grit, and well-water minerals have done to ductwork inside sprawling custom homes. Most of our Alamo calls start as a cleaning inquiry and turn into a repair job once we open a supply plenum and find separated joints, crushed returns, or rust-through from humidifier condensation. We run Rotobrush and Nikro systems to agitate and extract, then use Abatement Technologies negative-air filtration so what we stir up doesn’t end up in your living room. If your ducts are leaking, cleaning them twice won’t fix the problem. Call (855) 356-4417 for a straight answer on what your system actually needs.
Why Alamo Homes Are Different
Alamo’s housing stock runs large. Custom and ranch-style homes on one-acre-plus lots, most built between the 1960s and 1990s, with long rigid duct runs and multiple zones. Older Alamo homes often still have original sheet-metal ducts with joints that have loosened over 40 or 50 years of thermal cycling. The hot, dry summers and mild, wet winters mean ductwork expands and contracts constantly, and seasonal Diablo winds push dust and pollen straight into outdoor air intakes.
What catches people off guard is the well water. Most of Alamo runs on private wells and septic systems, and that high-mineral water leaves a crusty white scale on humidifier pads and inside supply plenums. Homes on Stone Valley Road and the hillside lots around it routinely show fine oak and grass pollen packed into duct branches each spring. Wildfire smoke from nearby hills adds another layer of particulate that settles in low-velocity branches. A basic shop-vac cleaning does not touch that. You need agitation, extraction, and real filtration.

Our Main Alamo Services
Two services dominate the calls we take from Alamo homeowners: full air duct cleaning for allergy and dust control, and dryer vent cleaning driven by fire prevention. Both run on the same professional-grade equipment platform.
Air Duct Cleaning in Alamo
Cleaning Alamo ductwork means dealing with what accumulates inside long, multi-zone systems in large estate homes. We connect Rotobrush rotary brush equipment or Nikro HEPA-filtered systems to the trunk line, then work branch by branch while Abatement Technologies negative-air equipment keeps the containment tight. Homes with Aprilaire or Honeywell whole-house filtration still need the ducts themselves cleaned, especially after wildfire smoke events. For the full scope, see our dedicated Air Duct Cleaning in Alamo page.

Dryer Vent Cleaning in Alamo
Alamo’s estate lots make for long dryer vent runs, often 20 feet or more through walls and crawl spaces. Lint settles in low spots, builds up, and becomes a fire hazard that no lint trap catches. We clean the full vent path with rotary brush equipment and verify airflow at the termination point. It is a fire-prevention service, not an upsell. Details on our Dryer Vent Cleaning in Alamo page.

Air Duct Repair in Alamo

Air duct repair in Alamo usually means restoring systems in homes built between the 1960s and 1990s, where original sheet-metal ductwork has separated at the joints or crushed in crawl spaces. The hot, dry summer cycles and wet winters here flex duct connections until they fail, and the result is conditioned air leaking into attics and crawlspaces while dust and insulation particles get pulled into the air stream. We handle full Air Duct Repair, not just a patch job, because a leaking duct is a design problem, not a cleanliness problem.
Ductwork Repair
Signs you need it
Rooms that never reach the thermostat setpoint, a persistent dusty smell when the blower kicks on, or visible disconnected duct sections in the attic or crawl space all point to ductwork repair.
What it costs in Alamo
Isolated joint sealing and reconnection in Alamo homes typically falls between $300 and $1,400 per section, depending on accessibility and duct diameter.
How we do it
We inspect the full accessible duct path, seal separated joints and seams with mastic and foil tape rated for HVAC temperatures, then verify static pressure and airflow before we leave.
Air Duct Replacement
Signs you need it
Cracked or crushed duct runs, rust-through on sheet metal, or fiberboard ducts that have absorbed moisture and lost structural integrity are replacement indicators, not repair candidates.
What it costs in Alamo
Full air duct replacement in Alamo generally runs $4,500 to $15,000 for a whole-home system, driven by run length, zone count, and crawl space or attic access difficulty.
How we do it
We remove the failed duct sections, install new rigid or flexible ductwork sized to the existing HVAC design, seal every connection, and balance the system across all zones.
What Air Duct Repair Costs in Alamo
| Item | Typical range in Alamo |
|---|---|
| Isolated duct joint sealing / reconnection | $300 – $1,400 |
| Partial system repair (multiple sections) | $1,400 – $4,500 |
| Whole-home air duct replacement | $4,500 – $15,000 |
Alamo pricing lands higher than tract-home cities because the houses are larger, the runs are longer, and crawl spaces on hillside lots add labor time. You get one flat price per job agreed before we start, not a per-vent number that grows on site.
Will I need a permit for duct repair in Alamo?
Most isolated duct sealing and repair jobs do not require a permit in Alamo, but full duct replacement as part of a larger HVAC scope may. We assess the job and tell you directly what applies to your property.
Is duct repair worth it before a cleaning?
Yes, especially in Alamo homes with 30-year-old sheet metal. Cleaning a leaking duct system is wasted effort. Repair the leaks first, then clean, and the air quality work actually holds. Call (855) 356-4417 to schedule an inspection.
Brands We Service in Alamo
We work alongside the filtration and humidification equipment already in many Alamo homes. Honeywell media cabinets and Aprilaire whole-house systems are common here, particularly on estate properties where air quality was part of the original build. We service those systems and coordinate duct cleaning around them. See our brands page for the full list. Turnaround on sourced parts is typically 2 to 3 business days.

FAQs About Air Duct Cleaning Company in Alamo
Most Alamo appointments are scheduled within 2 to 4 business days, depending on whether the job is cleaning, repair, or a combined scope. Estate properties with multiple zones take longer to quote and complete, so we typically do a walkthrough before scheduling the full job.
Some of Alamo’s gated communities have work-hours restrictions or require contractor notification before we bring equipment in. We ask about HOA rules when you book and handle the necessary coordination so the job does not stall at the gate.
Yes, those are standard equipment in many Alamo homes. We work around whole-house filtration and humidification setups without damaging media cabinets or bypass ducting, and we can replace humidifier pads that have crusted over from mineral-heavy well water.

What Alamo Customers Say
"Two guys, about three hours, plastic down at every register, and they wiped the vent covers before putting them back."
- Michelle Tran"They photographed every return and supply before starting and sent me the file afterward. No upsell to a sanitizing treatment I didn't need."
- Carrie Ziegler"My wife's allergies had been bad in this house since we moved in. It's been two months since they did the ducts and it's noticeably better. Not a miracle, but real."
