Air Duct Cleaning Company in Belmont, CA
Air duct repair in Belmont usually comes down to the same two problems: ductwork that was squeezed into a tight attic or crawlspace decades ago, and joints that have since pulled apart. Our technicians have up to 10 years of experience, and they work with contractor-grade Rotobrush and Nikro equipment rather than a shop vac on a hose. We clean ductwork, clear dryer vents, and repair what we find. Call (866) 894-2153 for a free estimate.
Why Belmont Homes Are Different
Belmont sits in the path of wildfire smoke coming off the Santa Cruz Mountains, and much of the town is built on hillsides under mature trees. That combination pushes smoke, ash, and pollen into return systems in a way that flatland cities like San Mateo or Redwood City don’t experience the same way. After a smoke event, technicians working the hillside neighborhoods near Waterdog Lake often find ash caked onto return-air grilles.
The housing stock explains the rest. Most of Belmont’s homes are 1940s to 1960s ranch and split-level builds on crawlspace foundations, with original galvanized or early flex duct still in place in plenty of them. Many hillside infill homes and older unpermitted additions had ductwork retrofitted into tight attic spaces, which leaves little room for proper support and sealing. Add the marine layer and cool, damp winters that keep crawlspaces and attics humid, and you get mold and musty odors forming inside duct runs that were never meant to see that much moisture. Together, smoke intrusion and damp crawlspaces make duct work in Belmont less about routine dust than about what accumulates season to season.

Our Main Belmont Services
Two jobs come up most often for Belmont homeowners: cleaning the duct system and clearing the dryer vent. Each has a dedicated page with the full detail.
Air Duct Cleaning in Belmont
Cleaning a Belmont system starts with containment. We set up Nikro HEPA negative-air equipment so debris pulled from the ducts is captured rather than pushed back into the living space, then run Rotobrush rotary brushes through the runs. On hillside homes with flex duct pulled loose during crawlspace sealing, the brush work reveals joints that need attention, which is when our repair capability earns its keep. Homes on crawlspace foundations with decades of accumulated debris see the clearest difference in airflow. Read the full page on air duct cleaning for scope and pricing.

Dryer Vent Cleaning in Belmont
Dryer vents are a fire-safety matter, not a cosmetic one. Lint builds up in the vent run and, given enough heat, it ignites. In older Belmont homes the vent often routes through a long, elbows-heavy path to an exterior wall, and those runs collect lint faster than a short straight vent does. We clear the full run and confirm airflow at the exterior termination. The complete scope is on our dryer vent cleaning page.

Air Duct Repair in Belmont
Air duct repair in Belmont tends to be a two-step job: clean the system, then reseal what the cleaning exposes. The housing stock drives most of it. Original galvanized duct from the 1940s through 1960s has usually lost its seam tape and mastic by now, and early flex duct in tight attic retrofits sags where it was never properly supported. Damp crawlspace air then finds every gap. If you’ve noticed rooms that never heat evenly, or a musty smell that comes back after a filter change, a repair assessment is where to start. Contractor-grade equipment and a written estimate before work begins keep the price clear.
Ductwork Repair
Signs you need it
You need ductwork repair when you can see disconnected joints, crushed flex runs, or tape peeling away at seams, or when a room stays cold or stuffy no matter what the thermostat says.
What it costs in Belmont
Ductwork repair in Belmont typically runs $250 to $900 per job, depending on how many joints and runs need attention and how accessible the crawlspace or attic is.
How we do it
We inspect and photograph each accessible run, reconnect and support loose sections, reseal seams with mastic and mesh tape, then confirm airflow at the registers before we leave.
Air Duct Replacement
Signs you need it
Replacement makes sense when the duct material itself has failed – torn flex duct, rusted-through galvanized runs, or ductwork that was retrofitted into an attic space too tight to seal properly.
What it costs in Belmont
Air duct replacement in Belmont typically runs $1,200 to $4,500, with the range set by run length, attic or crawlspace access, and how much of the system is being replaced.
How we do it
We map the existing layout, remove the failed sections, install new duct sized to the system, seal every joint, and verify static pressure and airflow at the registers once the new runs are in.
What Air Duct Repair Costs in Belmont
| Item | Typical range in Belmont |
|---|---|
| Ductwork repair (resealing, reconnecting joints) | $250 – $900 |
| Air duct replacement (partial to full system) | $1,200 – $4,500 |
| Duct cleaning combined with repair | $450 – $1,500 |
Access is the biggest cost swing in Belmont. Ductwork retrofitted into a tight attic takes more time to reach and seal than ductwork in an open crawlspace, and the more joints a system has, the more work resealing it involves. We set the price in writing before any work starts, so the number on the estimate is the number you pay.
Can you clean the ducts and repair them in the same visit?
Yes, and in Belmont it’s usually the right call. Cleaning with Rotobrush and Nikro equipment exposes loose joints and torn flex duct, and resealing those the same day prevents debris from re-entering the system.
How do I know whether my Belmont ducts need cleaning or repair?
Cleaning addresses accumulated dust, ash, and pollen; repair addresses physical damage like disconnected joints or crushed runs. If airflow is uneven or a damp smell persists, plan on an inspection first. We assess both and quote in writing. Call (866) 894-2153.
Brands We Service in Belmont
We work with equipment from Rotobrush, Nikro, and Abatement Technologies, plus Honeywell and Aprilaire systems for filtration and humidity control after the cleaning is done. If you’re weighing a post-cleaning filtration upgrade, we can advise on those systems with real knowledge. Turnaround on brand-specific questions is typically quick. See our brands for the full list.

What Belmont Customers Say
"Fair price and thorough work. They ran about an hour and a half past the estimated finish time, so don't schedule anything tight after."
- Hector Reyes"Quoted per system rather than the bait and switch per vent pricing everybody else in town uses. The number I was told on the phone was the number on the invoice."
- Steve Meyer"Did the dryer vent while they were here for a small add on price. The dryer now finishes a load in one cycle instead of two."
