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 in Randallstown, MD
Dryer vent cleaning in Randallstown almost always means working around the split-level homes that line Liberty Road and Offutt Road. These houses, most built between the late 1950s and early 1980s, have dryer vents that run through interior wall cavities and vertical chases rather than straight out an exterior wall. That means lint accumulates faster, access is harder, and the job takes longer than a simple ranch-style vent. If you need air duct cleaning in Randallstown, call (806) 606-6902 and we’ll give you a written price before any work starts.
Why Randallstown Homes Are Different
Randallstown grew fast along the Liberty Road corridor between the early 1960s and early 1980s, and the housing stock reflects that concentrated build-out. Split-levels, capes, and ranchers dominate, with the split-level being the most common and the most challenging for duct work. Return-air chases in these homes often run vertically between floors, framed into interior wall cavities during original construction. In many homes near Milford Mill Road, that means the “duct” is sometimes just a drywalled stud bay with no accessible lining. Cleaning, sealing, or sanitizing those cavities requires flexible access equipment and a clear scope of work before the job starts, because what the homeowner assumes is a lined duct run often isn’t.
Baltimore County’s humid subtropical climate adds another layer. Summer humidity regularly sits above 70-75% RH, and older supply runs with poor insulation develop interior condensation. That condensation is where mold and mildew start. Add the heavy tree canopy along stream corridors draining toward the Patapsco watershed, and you get seasonal pollen loads that clog return-air grilles and settle inside aging duct systems. The sheet-metal ductwork in these 40-60 year old homes was sized for older single-stage furnaces, and in many cases it has never been professionally cleaned. That combination, dense suburban build-out era, split-level floor plans with multi-zone duct runs, and aging systems, is the defining service reality here.
Our Main Randallstown Services
Most Randallstown homeowners call us for one of two jobs: a full air duct cleaning or a broader HVAC cleaning that includes the blower, coils, and plenum. Both are documented with before-and-after photos of every duct run.
Air Duct Cleaning in Randallstown
In a Randallstown split-level, air duct cleaning means running negative-pressure extraction through multiple zones, often with vertical return chases that branch off interior wall cavities. We photograph the inside of every run before and after, so you see exactly what was removed, whether it’s pulverized drywall dust from a past renovation or years of pollen and pet dander. For the full scope of this service in Randallstown, including pricing and what to expect, see Air Duct Cleaning in Randallstown.

HVAC Cleaning in Randallstown
HVAC cleaning goes beyond the ducts to the equipment itself: the blower wheel, evaporator coil, and plenum. On older Randallstown furnaces, a coated blower wheel can reduce airflow enough that the system runs longer and still doesn’t hit the thermostat setting. We clean the components, document what we found, and put the written scope in your hands before work begins. The dedicated page for this service is HVAC Cleaning in Randallstown, and it includes full pricing detail.

AfterDryer Vent Cleaning in Randallstown

Dryer vent cleaning in Randallstown often means working around a vent path that runs through an interior wall cavity or up through a roof chase, because the split-level floor plan puts the laundry room on a middle level with no direct exterior wall behind it. Lint builds up in those long, awkward runs faster than in a short through-wall vent, and in a humid Baltimore County summer, that lint can absorb moisture and compact into a blockage. We clean and document every inch of the Dryer Vent Cleaning run, with before-and-after photos included as standard.
Dryer Vent Inspection
Signs you need it
Your dryer takes longer than 45 minutes to dry a normal load, or you notice the laundry room feeling humid while the dryer runs.
What it costs in Randallstown
A dryer vent inspection in Randallstown typically runs $75-$125, and that fee is credited toward any cleaning we do on the same visit.
How we do it
We run a camera through the full vent path from the dryer connection to the exterior termination point, checking for lint build-up, crushed sections, and any gaps or separations.
Vent Cleaning
Signs you need it
There’s visible lint around the exterior vent flap, or the flap doesn’t open fully when the dryer is running.
What it costs in Randallstown
Standard dryer vent cleaning in Randallstown runs $150-$250, depending on the run length and access.
How we do it
We use a rotary brush with HEPA-filtered negative pressure at the dryer connection, then clean and test the exterior termination for proper airflow.
Lint Removal
Signs you need it
The dryer shuts off mid-cycle on its high-limit thermostat, or you smell a faint burning odor when the dryer runs.
What it costs in Randallstown
Heavy lint removal from a clogged or compacted vent in Randallstown runs $180-$300, depending on how far the blockage sits from the access point.
How we do it
We break up the compacted lint with a rigid auger, extract it under negative pressure, then camera-verify the vent is clear end to end.
What Dryer Vent Cleaning Costs in Randallstown
| Item | Typical range in Randallstown |
|---|---|
| Dryer vent inspection | $75-$125 |
| Standard dryer vent cleaning | $150-$250 |
| Heavy lint removal / clogged vent | $180-$300 |
Why does my Randallstown dryer vent clog so fast?
Split-level laundry rooms often route vents through interior chases with multiple elbows, and each elbow is a lint collection point. High summer humidity also makes lint sticky and more prone to compacting inside the run.
Can you clean a dryer vent that goes through the roof?
Yes. Roof-terminated vents are common in Randallstown split-levels, and we clean them from both ends, then verify with a camera that the full run is clear before we finish.
Duct Repair & Sealing in Randallstown

Duct repair and sealing in Randallstown almost always connects back to the same issue: sheet-metal ductwork installed 40-60 years ago, now leaking at the seams and joints. In split-level homes, those leaks are often hidden inside wall cavities and vertical chases where the original tape has dried out and separated. The result is conditioned air escaping into framing voids instead of reaching the rooms you’re trying to heat or cool. We repair and seal those runs, and we document the Duct Repair & Sealing work with photos before and after.
Duct Sealing
Signs you need it
Some rooms never reach the thermostat temperature, or your energy bill has crept up while the system runs the same hours.
What it costs in Randallstown
Duct sealing for accessible runs in Randallstown typically costs $350-$700, depending on the number of seams and joints we treat.
How we do it
We locate leaks with a pressure test or visual inspection, then seal seams and joints with mastic, not tape, so the seal flexes with the duct as it expands and contracts.
Flex Duct Repair
Signs you need it
You see crushed or kinked flex duct in an attic or crawlspace, or a room at the end of a flex run gets weak airflow.
What it costs in Randallstown
Replacing a short section of damaged flex duct in Randallstown runs $250-$450, depending on the diameter and how much of the run is affected.
How we do it
We cut out the damaged section, install a new properly supported flex run, and seal the connections with mastic and UL-rated connectors.
What Duct Repair & Sealing Costs in Randallstown
| Item | Typical range in Randallstown |
|---|---|
| Duct sealing (accessible runs) | $350-$700 |
| Flex duct repair (short section) | $250-$450 |
| Mastic sealant application | $150-$300 per zone |
Do I need duct sealing if I’m getting my ducts cleaned?
If the cleaning camera shows separated seams or visible gaps, sealing makes sense at the same time. We’ll show you the photo and give you a written separate price for the sealing work before we start.
Why can’t you just use tape on my duct leaks?
Standard cloth duct tape dries out and loses adhesion within a few years, especially in hot attics. Mastic stays flexible and bonds to the metal, which is why building codes require it for duct sealing.
Air Quality & Sanitizing in Randallstown

Air quality and sanitizing in Randallstown is less about luxury add-ons and more about what the local climate puts inside your ductwork. Sustained summer humidity above 70% RH creates condensation inside aging, poorly insulated supply runs, and that moisture lets mold and mildew establish in places you can’t see. The heavy deciduous canopy along the Patapsco stream corridors also means pollen works its way into return-air grilles every spring. We treat those conditions with Air Quality & Sanitizing products applied after the ducts are clean, so the sanitizer reaches the surface instead of coating a layer of dust.
Mold Treatment
Signs you need it
You smell a musty odor when the HVAC system runs, especially at the start of the cooling season, or you see visible mold around supply registers.
What it costs in Randallstown
Mold treatment for ductwork in a typical Randallstown home runs $400-$800, depending on the length of the duct runs and the extent of the affected area.
How we do it
We photograph the affected areas, apply an EPA-registered antimicrobial to the duct surfaces, and document the application with after-photos included in your job record.
Odor Removal
Signs you need it
There’s a lingering odor in the home that returns when the system runs, whether it’s from pets, cooking, or a past moisture event.
What it costs in Randallstown
Odor removal and neutralization in Randallstown typically costs $300-$500, depending on whether it’s a single zone or the full system.
How we do it
We identify the odor source, clean the affected surfaces, then fog or apply an odor-neutralizing treatment through the supply and return paths so it reaches the same spaces the air does.
What Air Quality & Sanitizing Costs in Randallstown
| Item | Typical range in Randallstown |
|---|---|
| Mold treatment (ductwork) | $400-$800 |
| Odor removal / neutralization | $300-$500 |
| UV light installation | $450-$900 |
Will sanitizing my ducts remove mold permanently?
Sanitizing kills surface mold and mildew, but it doesn’t fix the moisture problem that caused it. We’ll show you where condensation is forming and recommend whether insulation or sealing is the real solution.
Is the sanitizer you use safe for my family and pets?
We use EPA-registered products applied according to the label, and we’ll tell you the exact product name before any work starts. You won’t be asked to leave the house during treatment.
