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.

AfterAir Duct Cleaning Company in Mayo, MD
Air duct cleaning in Mayo, MD typically costs $350 – $650 for a whole-home system and is usually scheduled within a few business days. Homes here face a specific challenge: many sit closed up for months as seasonal properties, letting humidity and salt-laden bay air breed mold inside ductwork that year-round homes rarely see. At Hollis Air Duct Cleaning, we dispatch crews from our Baltimore office to handle these exact conditions, using antimicrobial treatments and professional-grade equipment from Rotobrush and Nikro. Call us at (361) 326-5060 for a free estimate.
Why Mayo Homes Are Different
Mayo sits on the Rhode River where it meets the Chesapeake Bay, and that waterfront position shapes every job we do here. The humid subtropical climate brings heavy summer moisture and damp winters, which means mold and mildew find ductwork fast, especially in homes that go unoccupied for stretches. Salt air off the bay accelerates corrosion on metal duct components, so we often find rusted registers and deteriorating fittings in older waterfront cottages.
The housing stock is mixed: original mid-century ranches with rigid metal ductwork, newer custom builds with flex duct systems, and aging waterfront cottages that may not have seen a cleaning in decades. Because Mayo has a significant share of second homes and weekend properties, we regularly encounter long-neglect scenarios where debris and microbial growth have had years to accumulate. That changes our approach. A standard rotary brush pass is not always enough; we assess whether antimicrobial treatment is warranted and check metal components for salt corrosion that could affect airflow or structural integrity.
Our Main Mayo Services
Mayo homeowners call us most often for these three services, each tailored to the local conditions:
Air Duct Cleaning in Mayo
We clean the full supply and return duct network using a Rotobrush rotary brush system combined with Nikro negative-air machines to pull loosened debris out of the home entirely. In Mayo, this often means addressing mold and musty odors from seasonal homes that have sat closed up through humid months. We inspect flex duct for sagging or damage common in older installations, and we apply antimicrobial treatment when microbial growth is present. Air Duct Cleaning in Mayo covers our full process and what to expect.
Dryer Vent Cleaning in Mayo
Lint buildup in dryer vents is a fire hazard anywhere, but in Mayo’s humid environment, moisture can compact lint into dense blockages that restrict airflow more severely. We use rotary brushes and high-velocity air tools to clear the full vent run, including through-wall and rooftop terminations common in waterfront homes. Our technicians check for corrosion on exterior vent hoods from salt exposure. Dryer Vent Cleaning in Mayo explains pricing and scheduling.
Duct Sealing in Mayo
Leaky ducts waste conditioned air and pull humid, unfiltered air into the system, which in Mayo means pulling in moisture that feeds mold growth. We seal joints and seams with mastic and reinforced tape, then pressure-test to verify results. This is especially valuable in older homes with original metal ductwork where seams have loosened over decades, and in seasonal homes where temperature swings have expanded and contracted fittings. Duct Sealing in Mayo details how we stop the leaks.
