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.

AfterFast, Reliable Air Duct Cleaning Across Dundalk
Air duct cleaning in Dundalk usually runs between $450 and $850 for a full system clean of a single-family home, and the work typically takes three to six hours. Those numbers assume a house with one furnace and standard duct runs. The moment a crawlspace or a 1920s-era return run enters the picture, the job changes, and so does the effort required to do it properly.
CleanRun Air Duct Cleaning has worked in Dundalk long enough to know which homes send a technician into a low attic off Stansbury and which send them under a Cape Cod off Dunmanway. We don’t dispatch from across the bridge and guess at the layout. Our crews know the housing stock, the moisture patterns near the Patapsco and Back River, and the duct failures those conditions cause. If you want a written price before anyone touches a panel, call (806) 606-6902.
Why CleanRun Air Duct Cleaning Is Dundalk’s Preferred Air Duct Cleaning Company
We show the work. That’s the whole model, and it matters more in Dundalk than almost anywhere we operate in Baltimore County. The housing stock here carries a contamination legacy that most companies never see because they never look. Our technicians photograph the inside of every duct run before and after cleaning, and the photos go to you as part of the standard job record. That’s Haven Standard practice, not an upsell. If something wasn’t removed, you’ll see it.
Tomas Reyes runs CleanRun under the Haven Standard, a written operating code that includes Clause 1: a written price before work begins, every time. No “call for a quote” routine. No hourly billing surprises. We’ve held to that since our first job in 2013, and over 52,000 homes later it hasn’t changed. Dundalk homeowners who call us get the same specific, line-item scope a homeowner in Middle River would get, because the price is tied to the duct system, not the ZIP code’s income bracket.
Our crews are background-checked, uniformed, and identified by name before they step onto your property. That’s Haven Standard Clause 3: Verified Crews. And every job, including crawlspace-heavy Dundalk runs, is backed by the 365-Day Done Right Promise in writing. If the work isn’t right, we make it right. Not a policy subject to manager approval. A written guarantee.
Our Air Duct Cleaning Services in Dundalk
Residential Duct Cleaning
Residential work in Dundalk is mostly pre-1970s housing stock: brick Cape Cods, row houses along Dundalk Avenue, and worker bungalows built for Sparrows Point shifts. Those homes were retrofitted with forced-air HVAC decades after construction, which means ductwork was added where it could fit, not where it should run. Our residential cleaning is a full source-removal process, not a vacuum pass, and it’s priced as a whole-system job, not per vent. That distinction matters when crawlspace returns run 40 feet under a home.
Commercial Duct Cleaning
Commercial properties along Merritt Boulevard and Holabird Avenue often have systems that haven’t been opened since the mill era. Restaurants, medical offices, and retail shops all circulate what sits in their ductwork. We schedule commercial Dundalk work with the same written pricing and documented photo record as residential jobs. The difference is scale and access, not standards. A property manager near Eastpoint Mall gets the same before-and-after visual record that a homeowner on Dunmanway gets.
Supply Duct Cleaning
Supply ducts are the conditioned air side of the system, and in Dundalk they frequently run through attics that hit 130 degrees in July. Heat plus decades of dust creates a baked-on layer that a rotating brush alone won’t remove. Our supply runs in Dundalk are typically cleaned with a Rotobrush agitation system paired with HEPA-filtered negative-pressure extraction. The combination breaks loose what’s adhered to the sheet metal and removes it, rather than just loosening it to resettle downstream.
Return Duct Cleaning
Returns in Dundalk homes are the worst section. They’re usually in crawlspaces, they’re rarely sealed well, and they pull from the dampest air in the house. The 1940s Cape Cods off Dunmanway and the ranchers near Battle Grove have return runs that collect both household dust and whatever the Patapsco humidity encourages to grow in it. We prioritize return duct cleaning here because skipping it makes any other duct work cosmetic. Our video inspection shows the return run before we touch it, and the photo record shows it after.

BeforeAfterTrusted Brands We Service in Dundalk
We run Rotobrush and Nikro equipment on Dundalk jobs because these are the brands a homeowner can research independently and verify. It’s not marketing language; it’s what’s on the truck. For filtration and air quality components, we stock Honeywell and Aprilaire products in standard sizes local Dundalk homes use. That means when your cleaning turns up a filter housing or media replacement need, we often have the part on hand and can price it in writing before installing anything. No second appointment, no second dispatch across the city.
Common Air Duct Cleaning Problems We See in Dundalk Homes
- Mill-era particulate in unsealed 1960s ductwork. Iron oxide and coke dust from Sparrows Point’s decades of operation infiltrated homes through unsealed joints. The debris pulled from Dundalk ductwork often has a dark, metallic-gray cast unique to this corridor of east Baltimore County. Source removal is the only fix; fogging does nothing to this material.
- Mold and mildew in crawlspace runs. The Patapsco and Back River keep ground-level humidity high year-round in Dundalk. Cape Cods and ranchers with crawlspace return ducts see microbial growth faster than homes on higher, drier ground in Glen Burnie or Essex. A proper clean addresses this with extraction and access, not a deodorizer spray.
- Deteriorated mastic-tape joints. The retrofitted galvanized sheet metal from the 1960s and 1970s was sealed with materials that have since dried and split. Torn joints pull unconditioned crawlspace air, insulation fibers, and moisture straight into the airstream. Sealing these during a cleaning is part of what we quote, not an add-on we “discover” later.
- Hard-to-reach returns in tight attics and low crawlspaces. Worker bungalows on 30-foot lots leave little room for access. Techs without experience in Dundalk’s housing stock either abandon these runs or puncture them trying. Our crews navigate the low clearances without damaging the runs, because we’ve seen hundreds of the same layouts.
Pricing for Air Duct Cleaning in Dundalk, MD
A typical Dundalk home with one HVAC system and standard runs costs $450 to $650 to clean. Add a crawlspace return and the range moves to $600 to $850 because the access is harder and the contamination is heavier. Row homes near the old mill footprint with short, direct runs often land on the lower end, while 1920s-era bungalows with retrofitted returns trend higher. Commercial spaces are priced per system after a walkthrough, with a written scope delivered before any work begins.
We don’t do per-vent pricing. We don’t do $79 coupon offers that multiply the moment a van arrives. One flat price per system, agreed in writing before a panel comes off. Bring a competitor’s written estimate and we’ll put our number next to it at no cost. That’s our Free Second Opinion policy, and it applies to every Dundalk quote we issue.

FAQs - Air Duct Cleaning in Dundalk
That gray-metallic cast is iron oxide particulate from the Sparrows Point steel mill’s decades of peak operation. Between the 1920s and the late 20th century, coke emissions and fine iron dust settled across Dundalk and infiltrated homes through unsealed 1960s duct joints. Ordinary household dust doesn’t have that color. The presence of this material means source removal was never done, or was done incompletely. A camera inspection will confirm the layer and its location, and only HEPA-filtered extraction with agitation will actually remove it. For an exact quote, call (806) 606-6902.
Dundalk sits between the Patapsco and Back River, two tidal tributaries that keep crawlspace humidity elevated year-round. In a 1950s Cape Cod, the return ducts often run through that damp crawlspace unsealed, pulling moist air into the airstream and condensing on cool galvanized sheet metal. Mold needs moisture, and these runs provide it. The fix is not a fog. It’s removing the buildup, killing what’s present, and sealing the joints so moisture stops entering. Call (806) 606-6902 and we’ll inspect your crawlspace runs with a camera before quoting.
No. Fogging disperses a mist that settles on surfaces and dissipates. It does not remove the dust, iron oxide particulate, or bio-film that’s already bonded to the duct walls. In Dundalk’s humid homes, that underlying material is exactly what provides the substrate for regrowth. Source removal with HEPA-filtered negative pressure and mechanical agitation is what actually removes the contamination. Fogging after cleaning can be part of an air quality program, but it is never a substitute for the cleaning itself. We’ll show you the before and after photos so you can see what was removed. Call (806) 606-6902.
Because retrofitted ductwork is unpredictable. When forced-air HVAC was added to 1920s and 1930s row homes in the 1960s, the duct routing followed whatever space existed. Runs were spliced, angled sharply, and sometimes terminated in plenums that were never designed for the airflow. A camera inspection maps what’s actually there before anyone pushes a brush through. It also identifies abandoned runs, crushed sections, and joints that have separated. In Dundalk, where many runs sit in tight basement ceilings and low attic spaces, this inspection prevents damage and ensures the cleaning covers the entire system. It comes standard with our quote. Call (806) 606-6902 to schedule one.
Most Dundalk homes benefit from a full duct cleaning every three to five years, though homes within a mile of the Patapsco or Back River with crawlspace returns may fall closer to the three-year mark. Elevated humidity plus the residual particulate profile of the Sparrows Point era means buildup accumulates faster here than in dryer, inland suburbs. If you haven’t had the work done since buying your home, or if you have documentation showing it was done once years ago, start with a video inspection to see where you actually stand. Call (806) 606-6902 and we’ll set it up.
