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 in Ellicott City, MD
Dryer vent cleaning in Ellicott City is the service we recommend most often to homeowners here, and the reason is simple: 1970s-1990s split-levels and colonials along Route 40, Centennial, and Turf Valley were built with long, often poorly routed dryer vents that accumulate lint faster than newer homes. The Patapsco river-valley humidity makes that lint dense and adhesive, not light and fluffy, which means it clogs faster and burns easier. If your dryer takes two cycles to finish a load, call us at (806) 606-6902 and we’ll put a written price in front of you before any panel comes off.
Why Ellicott City Homes Are Different
Ellicott City sits in a humid river-valley carved by the Patapsco watershed, and that topography changes how ducts behave. Summer humidity settles in and lingers far longer than in the open suburban terrain of neighboring Columbia or Catonsville, which means dust inside ductwork stays damp, sticks to the walls, and creates conditions where mold colonies take hold more readily. Homes in the broader Ellicott City area, particularly 1970s-1990s construction off Route 40 and around Centennial, often still carry original flex ductwork that has never been professionally cleaned. Flex duct sags, pinches, and collects debris at low points, and after thirty or forty years, we regularly document three-inch debris build-up at the first elbow on the first camera pass.
Lower Old Ellicott City is a different situation entirely. The 19th-century stone and brick commercial-residential buildings along Main Street were retrofitted with modern HVAC, and the duct routing in those structures is irregular, tight, and often inaccessible with standard tools. More important, the Tiber Branch floods of July 2016 and May 2018 pushed sediment and contaminated water into those systems. Technicians working lower Old Ellicott City routinely encounter duct interiors with visible silt lines or mold blooms left over from those floods. Homeowners often had visible flood repairs completed and never realized the damage extended into the HVAC system. That is a post-flood remediation concern specific to Ellicott City among Howard County suburbs, and it changes what we look for when we inspect those properties.
Our Main Ellicott City Services
Most Ellicott City homeowners start with one of two calls: full air duct cleaning for the whole system, or HVAC cleaning focused on the furnace, coil, and blower assembly. Both are covered in detail on their own pages, linked below.
Air Duct Cleaning in Ellicott City
Full air duct cleaning in Ellicott City covers every supply and return run, the plenum, and the register boxes. We use negative-pressure extraction with a Rotobrush or Nikro system, and every run is photographed inside before and after. For homes in the lower historic district with possible flood residue, this is the service that documents what’s actually inside. Air Duct Cleaning in Ellicott City has the full scope, pricing, and local details.
HVAC Cleaning in Ellicott City
HVAC cleaning in Ellicott City focuses on the indoor air handler: evaporator coil, blower wheel, condensate pan, and the cabinet interior. In this valley climate, coils run damp for much of the summer, which accumulates biological growth that reduces efficiency and pushes musty air through the house. HVAC Cleaning in Ellicott City explains the full process and what it costs here.

BeforeAfterDryer Vent Cleaning in Ellicott City
Dryer vent cleaning in Ellicott City is the service we recommend first to most homeowners because the housing stock makes it a genuine fire hazard. The 1970s-1990s colonials and split-levels along Route 40 and Turf Valley were built with dryer vents that run long horizontal distances through walls and ceilings, often with multiple elbows that catch lint at every turn. Add the Patapsco valley humidity, and that lint turns into a dense, paper-like plug that restricts airflow and raises the dryer’s internal temperature. Our Dryer Vent Cleaning service removes that plug and documents the result with before-and-after photos.
Dryer Vent Inspection
Signs you need it
Your dryer runs more than one full cycle to dry a normal load, or the outside vent flap doesn’t open when the dryer is running.
What it costs in Ellicott City
Inspection is included when bundled with a full vent cleaning, and as a separate call in Ellicott City it typically runs $95-$145 depending on access.
How we do it
We snake a camera through the entire vent run from the dryer connection to the outside termination, documenting every elbow and restriction before any cleaning begins.
Lint Removal
Signs you need it
Lint is visible at the outside vent opening, or the dryer shuts off mid-cycle with a high-heat error code.
What it costs in Ellicott City
Lint removal in Ellicott City typically runs $130-$220 for a standard single-story vent run, and more for longer runs or multi-story homes.
How we do it
We run a powered rotating brush through the full vent length, then remove loosened debris with negative air pressure so nothing blows back into the laundry room.
Vent Rerouting
Signs you need it
Your existing vent run is longer than 25 feet, has more than two elbows, or terminates in an inaccessible location that makes regular cleaning impractical.
What it costs in Ellicott City
Vent rerouting in Ellicott City typically runs $280-$450 depending on wall type, distance to outside, and whether we need to core through brick or siding.
How we do it
We map the shortest compliant route to an outside wall, run rigid metal duct where possible, and seal every joint with mastic before documenting the finished path.
Bird Guard Installation
Signs you need it
You hear scratching at the vent opening, see nesting material protruding from the termination, or find droppings on the siding below the vent.
What it costs in Ellicott City
Bird guard installation in Ellicott City typically runs $85-$160 per vent including the guard itself, installed at the outside termination.
How we do it
We remove any existing nesting material, clean the first few feet of the vent, and secure a metal guard over the opening that blocks birds without restricting airflow.
What Dryer Vent Cleaning Costs in Ellicott City
| Item | Typical range in Ellicott City |
|---|---|
| Dryer vent inspection | $95-$145 |
| Standard lint removal | $130-$220 |
| Vent rerouting | $280-$450 |
| Bird guard installation | $85-$160 |
How often should dryer vents be cleaned in Ellicott City?
Every 12 months for most Ellicott City homes, and every 6 months if your vent run exceeds 15 feet or your household runs more than five loads a week. The valley humidity makes lint denser here, so it accumulates faster than in drier neighboring areas. Call (806) 606-6902 and we’ll assess your run length at no charge.
Will cleaning my dryer vent actually make the dryer work faster?
Yes. In most Ellicott City homes we service, restricted vent airflow is the primary reason dryers take two cycles. After we clear the run and document it with photos, airflow returns to the manufacturer’s rated CFM and drying time drops measurably. If it doesn’t, the 365-Day Done Right Promise covers the follow-up.
Duct Repair & Sealing in Ellicott City
In the 1970s-1990s homes along Centennial and Turf Valley, we routinely find supply runs that have separated at the boot connection, pushing air into the floor cavity instead of the room. Duct Repair & Sealing is the service that restores the system to the airflow it was designed to deliver.
Duct Sealing
Signs you need it
Some rooms stay hot or cold no matter how you adjust the register, or your energy bills have crept up without a change in usage.
What it costs in Ellicott City
Whole-system duct sealing in Ellicott City typically runs $450-$900 for an average two-story home, including access labor and all materials.
How we do it
We locate every leak with a smoke pencil and pressure testing, then seal each joint and seam with mastic sealant rated for HVAC use.
Flex Duct Repair
Signs you need it
You have original 1970s-1990s flex duct that has visible sagging, kinking, or outer jacket tears in the attic or crawlspace.
What it costs in Ellicott City
Flex duct repair in Ellicott City typically runs $180-$320 per run, depending on whether we patch a section or replace the entire run.
How we do it
We cut out the damaged section, install matching R-value flex duct, pull it tight to eliminate sags, and seal both connections with mastic.
Metal Duct Repair
Signs you need it
You hear metallic popping or banging when the system cycles on or off, or you can see separated seams on exposed ductwork in the basement.
What it costs in Ellicott City
Metal duct repair in Ellicott City typically runs $220-$400 per section, depending on whether we reseal seams or replace a crushed segment.
How we do it
We repair or replace the damaged metal section, secure all connections with screws, and seal every seam with mastic to prevent air loss.
What Duct Repair & Sealing Costs in Ellicott City
| Item | Typical range in Ellicott City |
|---|---|
| Whole-system duct sealing | $450-$900 |
| Flex duct repair (per run) | $180-$320 |
| Metal duct repair (per section) | $220-$400 |
Can duct sealing really lower my energy bills in Ellicott City?
Yes, and measurably. In Ellicott City homes with 1970s-1990s ductwork, we commonly find 20-30% of conditioned air leaking into attics and wall cavities before it reaches a register. Sealing those leaks returns that air to the rooms you’re paying to heat and cool.
How do I know the repairs were actually done?
Every repair job includes our Documented Photo Record. We photograph the damaged run before, during, and after repair, and deliver those images as part of the written job record. You’ll see the finished mastic seams and the restored airflow path yourself.
Air Quality & Sanitizing in Ellicott City
Air quality and sanitizing in Ellicott City addresses what grows inside ductwork when valley humidity persists: mold, bacteria, and odor-causing buildup that standard cleaning removes but does not treat. This matters most in lower Old Ellicott City, where the 2016 and 2018 Tiber Branch floods introduced organic material into HVAC systems. Our Air Quality & Sanitizing service treats the system after cleaning so the interior is not just clean but biologically stable.
Mold Treatment
Signs you need it
You smell a persistent musty odor when the HVAC runs, or anyone in the house has unexplained allergy symptoms that improve away from home.
What it costs in Ellicott City
Mold treatment in Ellicott City typically runs $350-$650 for a full system, including cleaning the affected surfaces and applying the treatment.
How we do it
We clean the visible mold from accessible duct surfaces, then apply an EPA-registered antimicrobial that penetrates porous material and prevents regrowth.
Odor Removal
Signs you need it
A stale or sour smell comes from the registers every time the fan runs, even after the house has been aired out.
What it costs in Ellicott City
Odor removal in Ellicott City typically runs $200-$400 depending on the source, and is often added to a full duct cleaning.
How we do it
We identify the odor source, remove the underlying debris, and fog the system with a deodorizer that neutralizes rather than masks the smell.
UV Light Installation
Signs you need it
Your evaporator coil grows visible biological film, or you want continuous microbial control on the coil surface year-round.
What it costs in Ellicott City
UV light installation in Ellicott City typically runs $450-$800 including the unit, mounting, and electrical connection, installed at the coil.
How we do it
We mount the UV lamp at the coil with direct line of sight to the surface, wire it into the air handler, and verify operation before we leave.
What Air Quality & Sanitizing Costs in Ellicott City
| Item | Typical range in Ellicott City |
|---|---|
| Mold treatment | $350-$650 |
| Odor removal | $200-$400 |
| UV light installation | $450-$800 |
If my Ellicott City home flooded in 2016 or 2018, do I need sanitizing even if I already cleaned?
In many lower Old Ellicott City properties, yes. Floodwater carries organic material into ductwork, and cleaning removes the loose debris but does not address mold spores embedded in porous duct liner. Sanitizing treats that residual contamination. If you’re unsure, we can camera-inspect first.
Are the sanitizing chemicals safe for my family?
Yes. We use EPA-registered products applied according to label instructions, with the system off during application and a brief dwell time before the fan is restored. The written job record includes the product names and application details.
