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 Dundalk, MD
Air duct cleaning in Dundalk usually runs between $285 and $480 for a whole-home system, depending on home size and how much of the old Sparrows Point dust is packed into the ductwork. We’re Linden Air Duct Cleaning, and we’ve spent years working inside Dundalk’s homes – the post-war Cape Cods on Merritt Boulevard, the brick rowhouses off Holabird Avenue, the ranchers near Watersedge. These houses share something most other Maryland towns don’t: decades of iron oxide and industrial particulate that settled into ductwork while the Bethlehem Steel mill was still running full tilt. Every job here starts with a written price before any work begins, and you can reach us at (980) 447-2498 anytime – a live person answers, day or night.
Why Dundalk Homes Are Different
Dundalk sat downwind of the Bethlehem Steel Sparrows Point plant for over a century before it closed in 2012. During those decades, homes built in the 1940s through 1960s for steelworker families accumulated iron oxide dust, coke combustion byproducts, and fine metallic particulate that ordinary furnace filters never caught. That material settled into sheet-metal ductwork, and in many homes it’s still there today – reddish-brown dust that keeps showing up on registers along the Sparrows Point corridor no matter how often you swap the filter.
The housing stock compounds the problem. Most Dundalk homes are post-WWII Cape Cods, brick rowhouses, and modest ranchers built between the late 1940s and mid-1960s for mill and shipyard employees. That means 60 to 80-year-old sheet-metal ductwork with uninsulated, unsealed joints – systems that leak conditioned air into crawlspaces and pull moisture back in. Over the years, many of these systems had flex-duct sections retrofitted, creating hidden debris traps where dust, pet hair, and biological growth collect out of sight.
The geography adds one more layer. Dundalk is bounded by the Patapsco River, Bear Creek, and Back River tidal inlets, and that waterfront microclimate keeps humidity levels high through Baltimore’s long summers. Crawlspace-mounted ductwork – common in the area’s Cape Cods and ranchers – is especially vulnerable to moisture infiltration and mold risk inside leaky duct systems. A duct cleaning here isn’t the same job as one in a 1990s subdivision with modern sealed ducting. It’s older metal, heavier dust, and moisture you have to account for.
Our Main Dundalk Services
Dundalk homeowners call us most often for three things: getting the old industrial dust out of their ducts, keeping dryer vents from becoming a fire hazard, and repairing duct sections that have leaked or separated in crawlspaces. Each service has its own Dundalk page with full pricing and local details.
Air Duct Cleaning in Dundalk
Most Dundalk homes have never had a full duct extraction. What we pull out of these systems is distinctive – reddish-brown iron oxide dust and fine metallic particulate that settled into sheet-metal ductwork while the mills were running, and that no filter change will ever remove. We use negative-pressure extraction to pull that material out of every branch of the system, from the main trunk line down to individual registers. The job takes a few hours on a typical Dundalk Cape Cod, and you get a written price before we put a single tool on the van. Full details are on the Air Duct Cleaning in Dundalk page, including what a typical whole-home job costs.
Dryer Vent Cleaning in Dundalk
Dundalk’s older homes often have dryer vents that run from the laundry area through a crawlspace or exterior wall – routes that collect lint quickly and are easy to forget. Lint buildup in these vents is a fire hazard, and the humid waterfront air makes clumped, damp lint stick to vent walls even faster than it would inland. We clear the full vent run and check the airflow at the exterior termination point, so you can see the system breathing properly before we leave. See Dryer Vent Cleaning in Dundalk for a breakdown of what’s included and what it costs.
Air Duct Repair in Dundalk
Six decades of temperature swings and humidity have left many Dundalk duct systems with separated joints, crushed flex sections, and unsealed connections in crawlspaces – leaks that pull in humid air and send conditioned air into the dirt. We repair or replace the damaged sections, seal the joints, and wrap exposed runs where moisture is a problem. Every air duct repair in Dundalk is covered by a written guarantee, and if a covered repair doesn’t hold, we come back at no charge. Learn more on the Air Duct Repair in Dundalk page.

Pricing for Air Duct Cleaning Company in Dundalk, MD
Here’s what Dundalk homeowners can expect to pay for common jobs. These are whole-system ranges, not per-vent teaser prices that inflate once the technician is in your driveway:
| Service | Typical range in Dundalk |
|---|---|
| Whole-home air duct cleaning (smaller home, up to 6 vents) | $285 – $350 |
| Whole-home air duct cleaning (larger home, 10-12 vents) | $380 – $480 |
| Duct cleaning plus dryer vent cleaning (combined) | $325 – $400 |
| Dryer vent cleaning (standard wall or crawlspace run) | $85 – $150 |
| Dryer vent service with disassembly and reconnection | $120 – $190 |
| Air duct repair / replacing a section of supply ducting | $300 – $500 |
| Flex duct replacement for a failed section | $200 – $400 |
| Duct joint sealing and repair of small leaks | $125 – $300 |
| Adding or replacing insulation wrap on exposed ducting | $95 – $250 |
| Duct sanitizing treatment after cleaning | $150 – $250 |
What pushes a Dundalk quote toward the top of these ranges is usually the same thing: crawlspace access. Homes with ductwork running through tight, damp crawlspaces take longer to service and often need additional sealing or insulation work once we’re in there. Whatever the price turns out to be, it’s put in writing before any work begins – no surprise invoices at the end, ever.

FAQs About Air Duct Cleaning Company in Dundalk
Most Dundalk residences can be scheduled within a few business days, depending on the season. If you have a specific deadline – a home sale, a tenant move-in, a dust-sensitive family member – mention it when you call (980) 447-2498 and we’ll work with your timeline rather than make you wait on ours.
For single-family homes, no – duct cleaning and repair are routine maintenance and don’t require permits or HOA approval anywhere we’re aware of in Dundalk. Condo or townhouse owners should check their association rules, but the work itself falls under normal upkeep. We’ll note any access limitations before we start.
Often, yes. The iron oxide and industrial particulate that settled into Dundalk ductwork over decades is heavier and finer than household dust, so a basic surface brush won’t get it. We use negative-pressure extraction with agitation tools designed to dislodge caked-on material from sheet-metal walls, then seal any leak points so it doesn’t keep coming back from the crawlspace or attic. Call (980) 447-2498 for a free estimate and we’ll tell you exactly what your system needs.

"Thorough job on all eleven vents and the main trunk. Took longer than the three hours they quoted, but he told me early and kept working. Air feels fresher."
- Meredith L."Tech arrived with a badge and a printed sheet of what he'd be doing. Ran a camera through the main trunk before and after so I could see the dust difference. Vents smell cleaner already."
- Gina R."Priced by the system, not by the vent, and he told me up front. No pressure to add the sanitizer and I said no without any fuss."
- Faith N.
