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 Dundalk, MD
Most homes in Dundalk run between $390 and $585 for a full air duct cleaning, and the job typically takes 3 to 5 hours. The reason our work here doesn’t look like the work we do in Timonium or Catonsville comes down to what Dundalk is: a peninsula town built fast for steelworkers, where original 1940s and 1950s sheet-metal ductwork still carries the residue of the Sparrows Point mill. If you want a written price before we touch a single vent, call (469) 972-3151.
Why Dundalk Homes Are Different
Dundalk sits almost completely surrounded by tidal water. The Patapsco River runs along the south side, Back River along the north, and Bear Creek cuts straight through the interior. That geography keeps ambient humidity elevated year-round, which means condensation forms inside supply ducts during cooling season even in homes without obvious leaks. When that moisture meets the dust that’s been sitting in original ductwork since the Truman administration, you get mold. Not hypothetical mold, but the kind we see every week near Yorkway and Dunmanway.
The housing stock compounds the issue. Most of Dundalk’s homes are compact Cape Cods, duplexes, and brick row homes built between the late 1930s and early 1960s for Sparrows Point workers. Many still have their original galvanized duct systems, run through shallow crawl spaces and basement mechanical rooms that sit close to the water table. We walk into homes off Dundalk Avenue and find ducts that have never been opened since they were installed. The combination of tidal humidity, aging metal, and decades of deferred maintenance means a standard cleaning in Dundalk often requires a longer containment setup than the same square footage would inland.
Our Main Dundalk Services
Dundalk homeowners call us for two things: cleaning the ductwork that moves heated and cooled air through the house, and clearing the dryer vent that’s backing up behind the laundry room wall. Each has its own page with pricing and details.
Air Duct Cleaning in Dundalk
The homes around Bear Creek and Eastpoint tend to hold a fine reddish-brown dust inside their ducts, a legacy of decades of coke oven emissions and iron oxide from Bethlehem Steel. Cleaning that properly means setting up negative pressure before agitation starts, so the loosened particulates get pulled into our filtration system instead of drifting back into your living room. We run a Rotobrush through the supply and return lines, then the Nikro negative-air unit extracts what the brush dislodged. Full details are on the Air Duct Cleaning in Dundalk page.

Dryer Vent Cleaning in Dundalk
Dundalk’s humidity doesn’t just sit in the air. It settles into lint inside dryer vents, turning what would be a loose, fluffy blockage into a dense, matted plug that sticks to the vent walls. Laundry rooms in older row homes here often vent through short, sharp runs behind the basement wall, and we regularly find nests packed into exterior hoods near the eaves. We run a rotary brush the full length of the vent, then verify airflow with a pressure reading. The Dryer Vent Cleaning in Dundalk page walks through pricing and what to expect.
The other reason Dundalk jobs get scheduled weeks out is simply that the housing stock predates modern furnace filters. An original 1952 floor register wasn’t designed for a high-efficiency blower, and we routinely see return ducts packed with construction debris that was there before the homeowner was born.

Brands We Service in Dundalk
The equipment in Dundalk basements is as varied as the homes themselves. Most of the systems we open up pair a standard furnace with original galvanized ductwork, but we also work around newer installations with Guardsman filtration and Aprilaire-style media cabinets. If a homeowner wants better filtration after a cleaning, we stock Guardsman media and can have Honeywell and Aprilaire products on the truck within a day. See our brands for the full list of what we service.
Pricing for Air Duct Cleaning Company in Dundalk, MD
| Service | Typical range in Dundalk |
|---|---|
| Full system air duct cleaning (whole house) | $390 - $585 |
| Single furnace system cleaning | $320 - $410 |
| Additional return drop | $40 - $65 |
| Dryer vent cleaning (standard single-story route) | $90 - $145 |
| Dryer vent cleaning with roof termination | $115 - $175 |
| Rooftop or steep-access vent surcharge | $25 - $50 |

| Duct sanitizing / antimicrobial fog | $120 - $210 |
| Duct replacement (per linear foot) | $12 - $22 |
| Access panel installation | $45 - $85 |
Two things push Dundalk prices toward the upper end of those ranges. The first is access: crawl-space ductwork near the water table often means working in a space too shallow to stand in, which slows the job down. The second is containment. When we open up a return line and find the red iron-oxide dust that coats a lot of original systems near Sparrows Point Road, we spend more time on negative-pressure setup and HEPA filtration so that dust doesn’t end up on your furniture. Whatever the exact figure, you’ll have it in writing before we begin.

What Dundalk Customers Say
"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
- Rob Pendergast"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
