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.

Why Morton’s Air Duct Cleaning Is Corte Madera’s Preferred Air Duct Cleaning Company
We’ve been part of the Cedarwell family since 2005, and our reputation in Corte Madera has been built one home at a time. Homeowners here tell us they chose us after another company quoted a low teaser price, then billed double once the truck was in the driveway. That doesn’t happen with us. We put the full price in writing before anyone touches your system.
Our response time to Corte Madera is typically same-week scheduling, and we know the local housing stock: the post-war flatland tracts with original sheet-metal ductwork, the newer hillside builds with better sealing, and the specific contamination patterns that come from living adjacent to a tidal marsh. Our technicians are background-checked, uniformed, and trained to the Cedarwell C.A.R.E. values, which means shoe covers and drop cloths from the moment we walk in, quieter tools during nap hours, and pet-safe product choices where available. Every job ends with a photo of the clean-up before we leave, and every job is backed by our 365-Day Done Right Promise.
Commercial Air Duct Cleaning in Corte Madera
Commercial Air Duct Cleaning in Corte Madera covers office suites, retail spaces, medical clinics, and multi-tenant buildings along Tamalpais Drive and Paradise Drive, where HVAC systems run harder and longer than residential units. A typical commercial system in Corte Madera runs $1,200-$3,500 depending on square footage, access, and contamination level. We use Rotobrush and Nikro commercial-grade equipment with negative pressure containment, and we schedule around your business hours to minimize disruption.
System Assessment and Access Planning
Commercial duct networks in Corte Madera’s low-rise business parks often have access panels in ceiling plenums or mechanical closets that haven’t been opened in years. We map the full system first, identify every access point, and flag any fire-damper or smoke-detector wiring that needs protection before agitation begins.
Post-Clean Verification
After commercial cleaning, we provide before-and-after photos from the camera inspection, plus a written condition report. If we find moisture damage or degraded liner that requires replacement rather than cleaning, we document it with moisture readings and still images so your facilities manager has clear records for maintenance planning.
Air Duct Cleaning Services in Corte Madera
Air Duct Cleaning Services in Corte Madera address the specific problems this bay-marsh microclimate creates: dust bonded to duct walls by sustained humidity, degraded fiberglass liner shedding particles into living spaces, and active microbial growth in systems far younger than you’d see in drier inland towns. A typical residential whole-system clean in Corte Madera costs $450-$850, with video inspection, supply and return register cleaning, and negative-pressure HEPA extraction included. We use professional equipment from Honeywell and Aprilaire, not rental-grade shop vacs.
Video Inspection and Contamination Mapping
We start every Corte Madera job with a camera run through the supply and return trunks. This shows us exactly where dust is bonded, where liner is degraded, and whether we’re looking at a cleanable system or one with sections that need replacement. You see the footage too. No guessing.
Whole-System Source Removal
Our Nikro and Rotobrush systems use controlled agitation with simultaneous negative pressure, so debris is extracted at the point of disturbance rather than pushed deeper into the system. For Corte Madera’s older flatland homes with unsealed original ductwork, this matters more than in newer, tighter systems.

Trusted Brands We Service in Corte Madera
We clean and service systems with components from Honeywell, Aprilaire, and Abatement Technologies, and we carry common replacement parts for these brands on our Corte Madera service vehicles. That means faster turnaround when a filter housing, humidifier pad, or UV bulb needs attention during the same visit. We don’t sell equipment you don’t need, and we don’t push upgrades. If your Honeywell media air cleaner just needs a new filter and the housing is sound, that’s what we tell you.
Common Air Duct Cleaning Problems We See in Corte Madera Homes
- Degraded fiberglass duct liner in 1950s-60s flatland tracts. The original liner in these homes has absorbed decades of moisture-laden bay air. It sheds particles into the airstream and creates a musty odor at supply registers. Cleaning helps, but saturated or mold-compromised sections must be replaced.
- Active microbial growth in air handler cabinets. The sustained humidity on Corte Madera’s east side of Highway 101 keeps condensate pans and coil cabinets damp year-round. We find visible mold in systems less than ten years old, far sooner than in drier inland Marin towns.
- Return-air intakes pulling tidal-marsh particulates. Homes near the Corte Madera Ecological Reserve draw salt aerosols, wetland organic debris, and marsh-vegetation spores off prevailing bay breezes. This creates a distinct contamination profile, heavier on the return side than the supply side.
- Post-storm water intrusion with no documentation for insurers. After heavy rain or flooding, homeowners often don’t know whether ducts can be cleaned or must be replaced. Without moisture readings, photos, and camera stills, insurers routinely deny replacement claims.
Pricing for Air Duct Cleaning in Corte Madera, CA
A typical residential whole-system duct cleaning in Corte Madera runs $450-$850. Commercial systems range from $1,200-$3,500. What moves you within those ranges: system size, number of supply and return registers, accessibility of the main trunk lines, and whether video inspection reveals degraded liner or active mold that requires replacement rather than cleaning.
We give one flat price per system, agreed in writing before work starts. No per-vent pricing. No add-ons once we’re in your home. If camera inspection shows sections that need replacement, we stop, show you the footage, and quote that separately. You’ll never get an invoice you didn’t approve.

We Also Serve Cities Near Corte Madera
Our crews regularly work in Corte Madera and the surrounding Marin County communities: Larkspur, Mill Valley, Kentfield, and San Rafael. Each shares some of the bay-influenced climate patterns, but Corte Madera’s direct adjacency to the marsh creates the most pronounced moisture and contamination issues we see in this part of Marin.

FAQs About Air Duct Cleaning in Corte Madera
Ducts can be cleaned when the interior surfaces are contaminated but structurally sound, with no saturated insulation or active mold growth deeper than surface film. If fiberglass duct liner is waterlogged, delaminated, or shows active fungal colonization, the affected runs must be replaced, not cleaned, because source removal cannot restore compromised porous materials. We make this determination with moisture meters, borescope cameras, and photo documentation, and we show you the evidence before recommending either path. Call (323) 918-4345 and we’ll assess your specific situation.
We provide dated moisture-content readings from multiple points in the system, before-and-after camera inspection stills with location markers, a written narrative describing the water-intrusion line and its effect on duct materials, and our professional recommendation with reference to NADCA standards for post-flood HVAC restoration. Adjusters need this level of documentation to distinguish cleanable contamination from material failure. Our field vignette from a flatland home near the Corte Madera Ecological Reserve illustrates this: a homeowner’s blower motor was short-cycling with musty odors at the registers. Our tech found degraded fiberglass liner shedding into the airstream and active microbial growth in the air handler from years of moisture-laden bay air. We cleaned accessible runs under NADCA standards with negative pressure and HEPA filtration, but flagged compromised liner sections as replace-only, documenting pre- and post-condition with photos and moisture readings so her insurer could see the water-intrusion line clearly.
The prevailing bay breezes across the Corte Madera Marsh carry salt aerosols, wetland organic debris, and marsh-vegetation spores directly into return-air intakes on the flatland’s east side. Marine fog funnels in off Richardson Bay and along the Corte Madera Creek corridor, keeping relative humidity measurably higher here than in inland Marin towns like San Anselmo or Fairfax. That sustained dampness causes dust to bond to duct walls more aggressively and accelerates the breakdown of fiberglass duct liner, which then sheds particles and supports microbial growth. Homes just a mile west toward the Tam foothills draw predominantly inland air and show these problems far less frequently.
We clean both. Our commercial work covers office suites, retail spaces, medical clinics, and multi-tenant buildings along corridors like Tamalpais Drive and Paradise Drive. Commercial systems are priced and scoped separately from residential jobs because of larger equipment, extended runtime, and the need to schedule around business hours. Call (323) 918-4345 to discuss your building’s specific layout and usage pattern.
Most of these homes have original sheet-metal ductwork with minimal sealing and no vapor barriers, installed when the flatlands were first developed. Our typical job starts with video inspection to assess liner condition and locate any moisture damage. We then seal the access points, apply negative-pressure HEPA extraction with Rotobrush or Nikro agitation tools, clean all supply and return registers, and finish with a second camera run to verify results. If inspection reveals degraded liner or active mold, we flag those sections for replacement and document everything for your records. The whole process usually takes a single morning or afternoon, and we protect your floors with drop cloths and shoe covers throughout.
