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.
Air Duct Cleaning Company in Catonsville, MD
Air duct cleaning in Catonsville deals with a specific set of conditions: older homes with original sheet-metal ductwork, a heavy tree canopy that drops pollen and seed debris year-round, and humidity from the Patapsco River valley that pushes moisture into basements and crawlspaces. Most Catonsville homes fall between $350 and $650 for a full system cleaning, depending on home size and how much material has accumulated. We’re Kestrel Air Duct Cleaning, led by Dale Whitmore, and every job gets a written price before work starts. Call (469) 972-3151 for details.
Why Catonsville Homes Are Different
Catonsville carries a Tree City USA designation, and anyone who has driven Frederick Road or the side streets off Edmondson Avenue knows why. Mature oaks, maples, and elms form a near-continuous canopy over most residential blocks. That canopy is beautiful, but it loads the air with oak tassels in spring, maple seeds in early summer, and leaf-mold spores through fall. Older duct systems pull that material in through attic and crawlspace returns, and it settles in the ducts.
The housing stock compounds the issue. The brick Cape Cods, ranchers, and colonials built between the late 1940s and early 1970s mostly retain their original ductwork. Unsealed sheet-metal joints and degrading fiberglass duct liner are common. When humid air rises from the Patapsco valley into basements and crawlspaces, it creates conditions where mold can colonize inside ducts, not just dust collecting on surfaces. Technicians working east of the UMBC campus regularly find ducts clogged with a mix of fine organic debris and black mold, a combination tied directly to the canopy over older homes with leaky return-air chases.
Our Main Catonsville Services
Catonsville homeowners call us most often for two services. Each has its own dedicated Catonsville page with pricing, process details, and FAQs.
Air Duct Cleaning in Catonsville
Full-system air duct cleaning in Catonsville means pulling years of accumulated material out of supply and return ductwork, the air handler, and the plenum. In Catonsville, that material is usually a mix of construction dust, insulation particles from degrading duct liner, pet dander, and organic debris from the tree canopy. We run negative-air extraction with HEPA filtration so loosened particles are pulled out of the living space rather than blown through it. See the full breakdown on our Air Duct Cleaning in Catonsville page.

Dryer Vent Cleaning in Catonsville
Dryer vents in Catonsville clog faster than homeowners expect, partly because older homes have longer vent runs and partly because humid air makes lint stick to the vent walls rather than blow through. A restricted dryer vent means longer dry times and a real fire risk. We clean the full run from dryer to exterior termination, clearing the lint trap bypass and checking airflow at the exit point. Details are on the Dryer Vent Cleaning in Catonsville page.

What Catonsville Customers Say
"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
- Preston Ngata"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
