We’re not strangers to Corte Madera. Brian Rivera — owner and lead technician — has been cleaning ducts in this town for fourteen years, and we’ve learned that Corte Madera isn’t a generic Marin County job. The marsh-adjacent humidity, the fog funnel that sits on the bay side, and the concentration of 1950s and 1960s ranch homes with original duct systems make this one of the most specialized air quality markets in the North Bay. Our Air Duct Cleaning team brings Rotobrush and Nikro equipment, not the light-duty tools a generalist HVAC company keeps for occasional duct work.

Our Air Duct Cleaning Services in Corte Madera
Residential Duct Cleaning
Corte Madera’s housing stock is dominated by ranch-style and split-level tract homes built in the 1950s and 1960s — now fifty to seventy years old, with original forced-air systems that have never been properly cleaned. We use Rotobrush agitation and HEPA vacuuming to remove decades of accumulated debris from these older systems without damaging fragile duct board lining. A typical Corte Madera residential cleaning runs $350–$650 for a single-system home, with larger split-levels or homes with multiple zones ranging $550–$850.
Commercial Duct Cleaning
The commercial buildings along Tamalpais Drive and near the Corte Madera Town Center face the same marsh-influenced air quality challenges as residential properties, but with higher occupancy loads and more complex rooftop HVAC configurations. We deploy Abatement Technologies HEPA filtration and negative air machines for commercial jobs, containing debris during cleaning so your business doesn’t shut down. Commercial duct cleaning in Corte Madera typically starts at $800 for small retail or office spaces and scales based on system complexity.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces — and in Corte Madera’s older homes, they’re often lined with deteriorating duct board that sheds fibers and traps organic material. We clean supply lines with controlled agitation that removes contamination without dislodging fragile lining. Homes in the flat neighborhoods east of 101 frequently need supply duct sealing after cleaning, as the original connections have loosened over decades of thermal expansion. Supply duct cleaning as a standalone service in Corte Madera runs $200–$400.
Return Duct Cleaning
Return ducts are where Corte Madera’s unique environmental conditions hit hardest. These are the intake pathways that draw air directly from your home — and in marsh-adjacent properties, that air carries elevated humidity and organic spore loads. Return duct cleaning is often where we find the most significant mold colonization, especially in homes with crawlspace-routed returns sitting near the water table. We prioritize return duct cleaning in Corte Madera jobs, using Nikro HEPA vacuum systems and, when needed, Honeywell and Aprilaire filtration upgrades to prevent recontamination. Standalone return cleaning: $250–$450.
Full System Cleaning
Full system cleaning is what most Corte Madera homes actually need — not isolated supply or return work, but comprehensive treatment of the entire duct network, registers, grilles, and HVAC cabinet. We include video inspection before and after, so you see the difference. For Corte Madera’s 1950s-60s housing stock, full system cleaning typically runs $550–$950 depending on home size, contamination level, and whether mold remediation or duct sealing is required. This is our most booked service in 94925.
Video Inspection
Video inspection reveals what Corte Madera homeowners can’t see — and often explains what they’ve been smelling. We feed high-resolution cameras through the duct system, documenting deterioration of duct board lining, moisture intrusion points, mold colonies, and debris accumulation. Brian Rivera reviews the footage with you in real time, pointing out exactly what needs attention and what doesn’t. Video inspection as a standalone diagnostic runs $150–$250 in Corte Madera, and is waived when you book a full cleaning.

Trusted Brands We Service in Corte Madera
We don’t show up with generic equipment. Every Corte Madera job deploys professional-grade tools: Rotobrush and Nikro for mechanical agitation and HEPA vacuuming, Abatement Technologies for containment and air scrubbing on mold remediation work, and Honeywell and Aprilaire filtration products for system upgrades. We stock Aprilaire media filters and Honeywell electronic air cleaner components locally, so Corte Madera customers don’t wait for parts. For sanitizing applications after mold removal, we use Guardsman-grade treatment products — the same antimicrobial formulations used in commercial remediation, not consumer-grade sprays.
Common Air Duct Cleaning Problems We See in Corte Madera Homes
- Active mold in duct board lining. The original fiberglass duct board in 1950s-60s Corte Madera ranch homes deteriorates over decades, its binder breaking down until the surface becomes porous and absorbent. Combined with the elevated humidity from the adjacent marsh, this creates ideal conditions for mold colonization that standard dust removal won’t address.
- Moisture-trapping flex duct connections in crawlspaces. Original flex duct runs beneath homes east of Highway 101 sit close to the water table in crawlspaces that rarely dry out completely. These connections sag, pool condensation, and trap organic debris — a chronic problem in Corte Madera’s flat neighborhoods that hillside Marin towns simply don’t experience.
- Misattributed musty odors. Homeowners near the Corte Madera Marsh often blame persistent mustiness on the tidal wetlands, leaving windows open and air purifiers running without inspecting the actual source. We’ve found that sealing and cleaning the duct system eliminates what residents assumed was an unavoidable feature of bay-adjacent living.
- Fiber shedding from degraded duct surfaces. Seventy-year-old duct board lining in Corte Madera’s original housing stock breaks down into respirable fibers that circulate through living spaces. This isn’t dust — it’s structural deterioration of the duct material itself, visible on video inspection as a fuzzy, degraded surface.

FAQs — Air Duct Cleaning in Corte Madera
The musty odor is likely coming from inside your ducts, not through your windows. We recently cleaned a 1958 ranch home on Paradise Drive east of 101 where the homeowner had blamed a persistent musty odor on the marsh breeze. Our video inspection revealed active mold colonies coating the old duct board lining and clogging the original flex duct connections. We used Rotobrush agitation and HEPA vacuuming to remove the biological growth, then installed a new Aprilaire media filter at the return to prevent recontamination. The musty smell vanished — the homeowner was surprised the ducts, not the marsh, were the source. Call (855) 908-0725 for a free video inspection if you’re fighting unexplained odors in 94925.
Yes, original duct board can be cleaned, but it requires gentler agitation than metal ductwork and honest assessment of whether the lining has degraded past salvage. In Corte Madera’s 1960s tract homes, we frequently find duct board that’s structurally intact but surface-degraded — cleanable with controlled Rotobrush contact and HEPA extraction. When the lining is actively shedding fibers or delaminating, we’ll show you on camera and discuss whether spot repair, full duct replacement, or sealing is the right next step. Cleaning a 1960s Corte Madera system typically runs $450–$750. Call for an exact assessment — estimates are free.
Homes east of Highway 101 in Corte Madera should be inspected every two to three years and cleaned every three to five years — more frequently if you have allergies, recent water intrusion, or visible mold at registers. The marsh-adjacent humidity and organic spore load mean ducts here accumulate biological contamination faster than in drier Marin locations. If you smell mustiness or your HVAC runs constantly without moving air effectively, don’t wait for a scheduled cycle. Call (855) 908-0725 for a video inspection.
Duct cleaning removes the accumulated salt and moisture that accelerate corrosion inside your system, but it won’t eliminate salt exposure at the outdoor condenser or air handler. For Corte Madera homes, we recommend combining duct cleaning with a corrosion-resistant filter upgrade — Aprilaire media filters handle the particulate load better than standard one-inch fiberglass — and periodic coil cleaning to address the external equipment. Full system cleaning plus coil treatment runs $750–$1,100 in Corte Madera. Call for specifics on your setup.
Video inspection is essential for 1950s ranch homes in Corte Madera, not optional. Original duct board from this era has had seventy years to deteriorate, and we regularly find hidden mold, disconnected flex runs, and deteriorated lining that homeowners had no idea existed. The $150–$250 inspection cost is waived when you proceed with cleaning, and it prevents the most common complaint we hear: “I paid for cleaning but nobody told me the ducts were falling apart inside.” For Corte Madera’s legacy housing stock, see before you spend. Call (855) 908-0725 to schedule.
