Air Duct Cleaning Company in Lafayette, CA
Air duct repair in Lafayette usually means one of two things after a long fire season: smoke-damaged flex duct that has to be cut out and replaced, or original 1960s-1970s metal duct with joints that have worked loose over decades of Diablo wind cycles. Hallmark Air Duct Cleaning has served Lafayette since 2011, and we run Rotobrush and Nikro extraction equipment alongside full duct repair capability so the same crew that finds the leak can fix it. Call (833) 467-6681 to schedule an inspection.
Why Lafayette Homes Are Different
Lafayette’s housing stock is mostly large custom and semi-custom homes built between the 1960s and 1990s on half-acre-plus lots threaded through oak and eucalyptus. Those homes carry long trunk-and-branch duct systems with multiple zones, vaulted ceilings, and additions or second units tacked on over the years. The extra runs were often flex duct added quickly, and in the older ranch-era homes off Reliez Valley and Happy Valley, original flex duct and poorly sealed joints are common. When we open a return plenum in Lafayette, we are usually looking at decades of accumulated material, not a year or two.
The climate does its own work. Hot, dry summers pull wildfire smoke and ash into hillside homes during fall Diablo wind events, while mild, damp winters leave duct interiors prone to musty buildup. That smoke-season urgency is the real driver here. Homeowners on narrow, winding canyon driveways also need a crew that can get a smaller van setup to the house, which changes how we stage equipment. Long empty duct runs in large hillside homes mean containment matters more here than in flat, grid-suburb neighbors like Walnut Creek.

Our Main Lafayette Services
Most Lafayette homeowners call us for one of two reasons: smoke-odor and ash removal after burn days, or a dryer vent that has never been properly cleaned in a home where the laundry room sits deep in the floor plan. Here is what each service involves here.
Air Duct Cleaning in Lafayette
After a red-flag burn day, ash and char smell get pulled deep into return plenums and second-floor runs of hillside homes. Our Air Duct Cleaning in Lafayette service uses Rotobrush rotary-brush extraction matched to the duct type, with Abatement Technologies negative-air containment so what we dislodge is captured, not pushed into living space. Long, multi-zone systems in Lafayette custom homes take longer to clean properly than a typical suburban ranch. We clean, then we check every accessible joint for the leaks that let smoke re-enter between seasons.
Dryer Vent Cleaning in Lafayette
Lafayette laundry rooms are often on interior walls or upper floors, which means long dryer vent runs with elbows and horizontal sections where lint stalls and compacts. We treat Dryer Vent Cleaning in Lafayette as a fire-risk reduction service, not a quick add-on. A dryer vent in a Lafayette hillside home can run 20-plus feet to an exterior wall, and in older homes that vent may not have been cleaned since installation. We use dedicated rotary equipment to clear the full run and confirm airflow at the termination point before we leave.
Air Duct Repair in Lafayette
Air duct repair in Lafayette is rarely about a single visible hole. It is usually about the cumulative result of decades: original flex duct in 1970s hillside homes that has split along the wire helix, metal duct joints that pulled apart as the house settled on canyon soil, and second-story runs added during remodels that were never sealed correctly. Smoke season makes these failures obvious because the same leaks that waste conditioned air also pull ash into places a sealed system would keep out. Hallmark Air Duct Cleaning handles repair in-house because a cleaning that does not fix the leak just means recontamination within months. Our Air Duct Repair work covers the full scope from inspection to sealed, functioning ductwork.
Air Duct Replacement
Signs you need it
You see visible mold on flex duct insulation, sections have collapsed or torn, or smoke odor returns within days of a cleaning.
What it costs in Lafayette
Air duct replacement in Lafayette typically runs $1,800 to $4,200 depending on the linear feet, access difficulty, and whether we are replacing flex or rigid duct.
How we do it
We remove the failed duct, size the replacement to the room load, hang and seal the new run with mastic and UL-listed tape, then test airflow at the register.
Ductwork Repair
Signs you need it
You feel weak airflow in one or two rooms, notice dust accumulating faster in certain areas, or see sections of duct hanging loose in a crawlspace or attic.
What it costs in Lafayette
Ductwork repair in Lafayette generally falls between $350 and $900, though access issues in steep hillside crawlspaces or vaulted-ceiling attics push toward the higher end.
How we do it
We locate the failed joint or torn section, re-secure and seal with mastic, repair or replace the damaged segment, and then run a system airflow check.
What Air Duct Repair Costs in Lafayette
| Item | Typical range in Lafayette |
|---|---|
| Air Duct Replacement | $1,800 – $4,200 |
| Ductwork Repair | $350 – $900 |
| HVAC Duct Installation | $2,800 – $5,800 |
Access is the biggest cost variable in Lafayette. A crawlspace under a 1970s hillside home with 18 inches of clearance takes longer than a flat-lot rancher. Vaulted ceilings and second-story duct runs also add labor. We quote one flat price per repair job before work starts.
How long does duct repair take in Lafayette?
Most duct repair jobs in Lafayette finish in half a day to a full day. Replacement of long runs or multiple sections can stretch to two days, especially when attic access requires staging on a hillside lot.
Do I need a permit to replace ducts in Lafayette?
Most duct repair or replacement work does not require a permit in Lafayette, but additions or major system changes may. We can advise on what your specific job needs before work begins.
Brands We Service in Lafayette
We work on systems built around equipment from Rotobrush, Nikro, Abatement Technologies, and Guardsman. The parts we need are stocked locally in the East Bay, so turnaround on repair work stays short. See our brands for the full range.

What pushes price up in Lafayette is the house itself: long duct runs on large floor plans, crawlspace or attic access that slows the work, and multi-zone systems that demand more labor per register.

What Lafayette Customers Say
"Ran a negative air machine on the whole system rather than the shop vac on a stick that the cheap outfit down the road uses. Showed me the before and after photos from inside the trunk line and it was genuinely disgusting."
- Wade Reed"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."
- Beatriz Hernandez"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
- Kurt Doyle
