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.

We’ve been working in Sterling since 2013, and our crews know the specific vent configurations you’ll find in neighborhoods like Broad Run Farms, Moorefield Village, and the townhouses near Loudoun Station. These aren’t generic suburban homes - they’re late-1980s to late-1990s builds with long second-floor dryer runs, original flex duct, and decades of lint accumulation that a shop vac won’t touch. Our Dryer Vent Cleaning team photographs every run before and after, so you see what was actually in there.
Why CleanRun Air Duct Cleaning Ashburn Is Sterling’s Preferred Dryer Vent Cleaning Company
Sterling homeowners tend to research before they call, and we built our process for exactly that customer. Every estimate is written and delivered before work starts - Haven Standard Clause 1 - so the price you agree to is the price on the invoice. No per-vent add-ons, no “we found something unexpected” upsells once the truck is in your driveway.
Our documented photo record is included on every visit. The camera shows the 3-inch lint build-up at the first elbow, or the crushed flex behind the laundry room wall, or the bird nest blocking the vent cap - and the after photo shows the same run clear. We’ve delivered this record to more than 52,000 homes since 2013, and we can show you examples from Sterling jobs specifically.
Scheduling and dispatch are coordinated from our Washington, DC office, but the crew that arrives at your Sterling home is local, uniformed, background-checked under Haven Standard Clause 3: Verified Crews, and identified by name before arrival. All calls are answered by a live person, 24/7.

Our Dryer Vent Cleaning Services in Sterling
Dryer Vent Inspection
Our inspection starts with a camera run from the exterior vent cap through the full duct length. In Sterling’s older tract homes - particularly the colonials and townhouses built during the Dulles tech-corridor boom - we regularly find sagging flex duct at low points where lint has compacted into dense pockets. The camera also documents the dark particulate coating we see in homes beneath Dulles flight corridors, a pattern rarely found just a few miles west in Ashburn. You receive the photo record as a standard deliverable.
Vent Cleaning
We clean with agitation tools under negative-pressure extraction (a suction system that pulls dislodged debris out of your home, not into it). This matters in Sterling because the long second-floor runs in Potomac Falls and Broad Run Farms homes often exceed 25 feet, and standard homeowner brushes can’t maintain contact pressure through that length. Our Rotobrush system scrubs the full diameter while the Nikro negative-pressure unit captures the lint. The result is documented before and after.
Lint Removal
Lint removal is the core of fire prevention, but in Sterling it’s also about restoring dryer efficiency. The humid DC metro summers - 70-80% relative humidity through July and August - mean wet loads take longer to dry, and a partially blocked vent compounds that cycle time. We pull lint from the full run, not just the trap and the first accessible section. In homes near Belmont Ridge Road and Waxpool Road, we’ve measured cycle-time reductions of 30-45 minutes after full lint removal.
Vent Rerouting
Some Sterling homes have dryer runs that were never designed to move lint efficiently. The original builder routed flex duct through unconditioned attic space with multiple elbows, or the run exceeds 35 feet without a booster fan. We reroute with rigid duct where possible - shorter path, fewer turns, better airflow. This is common in the two-story colonials near Holly Knoll and the Dulles-area subdivisions along Loudoun County Parkway. Every rerouting plan is drawn and priced in writing before we cut access.
Bird Guard Installation
Original vent caps on 1987-2002 Sterling homes have often failed or were never bird-proof. We install Guardsman vent caps with integrated bird guards that maintain airflow while blocking nesting. This is a standard add-on during cleaning, and we stock them for Sterling jobs so there’s no delay.
Vent Cap Replacement
Cracked or missing flappers let rain into the duct and humid air back into the laundry room. We replace with Aprilaire and Abatement Technologies caps rated for the DC metro’s freeze-thaw cycles.

Our equipment roster includes Rotobrush agitation systems, Nikro negative-pressure extractors, and Abatement Technologies HEPA filtration - brands you can look up independently before agreeing to any work. We also stock Aprilaire vent caps and Guardsman bird guards for Sterling jobs, so replacements happen same-visit rather than “we’ll order that and come back.” For homes near Trail Marker 10 or Trail Marker 7, where crews are already in the neighborhood regularly, parts availability means we can complete vent rerouting or cap replacement without a return trip.
Common Dryer Vent Cleaning Problems We See in Sterling Homes
- Crushed flex elbows behind finished walls. In Moorefield Village and Potomac Green, the original flex duct was jammed against studs during construction or crushed by decades of vibration. Lint packs into these choke points until airflow is reduced by half. Our camera locates them; agitation tools under negative pressure clear them.
- Bird nests in failed vent caps. The builder-grade caps on Sterling’s 1990s homes lose their flappers or screen. Birds nest in the duct, blocking lint escape entirely. We remove the nest, clean the run, and install a Guardsman bird guard so it doesn’t repeat.
- Excessively long second-floor runs without booster fans. Potomac Falls and Broad Run Farms homes often have 30-40 foot runs through unconditioned attic space. Gravity and length work against lint transport. We evaluate whether rerouting or a booster fan is the right fix, and we put that recommendation in writing.
- Jet-exhaust particulate in mechanical chases near Dulles. Homes beneath arrival and departure corridors - particularly in the Dulles neighborhood and Broad Run Farms - show a fine dark coating in dryer vent runs that share attic space with HVAC returns. This isn’t lint; it’s accumulated particulate from decades of airport-proximity air intake. We document it and clean it, but we also flag it as a reason to inspect your full duct system.

FAQs - Dryer Vent Cleaning in Sterling
A clogged vent shows specific symptoms: loads take more than one cycle, the laundry room feels humid or smells hot, and the exterior vent flap barely moves when the dryer runs. In Sterling’s older homes, we also see lint blowing back into the laundry room from a disconnected joint behind the wall. Run the dryer on high heat and check the exterior flap - if it doesn’t lift fully, the vent is restricted. Call (240) 771-1508 and we’ll camera-inspect it; the inspection fee credits toward cleaning if you proceed.
Sterling’s late-1980s to late-1990s homes were built with longer dryer runs and original flex duct that sags and kinks at low points. Those kinks create lint pockets a standard trap can’t prevent. If your previous home had a short, straight run to an exterior wall, it self-cleaned with airflow. Your Sterling home’s second-floor run through the attic doesn’t. The 25-35 years of accumulated micro-sagging in these ducts is the difference.
Yes. Technicians working these neighborhoods regularly find a fine dark particulate coating the duct boots and main trunk lines - consistent with jet exhaust from Dulles arrival and departure corridors. Prevailing westerly winds push this exhaust directly over homes near Loudoun County Parkway and Broad Run Farms. It’s not hazardous in the concentrations we see in dryer vents, but it confirms these mechanical chases are drawing in airport-proximity air, and it often prompts us to recommend a full HVAC duct inspection. We document everything we find in the photo record.
Often yes. We locate the crush with the camera, then determine if we can pull new rigid duct through the existing chase from attic or basement access. In a recent Moorefield Village job, we found a crushed flex elbow behind the second-floor wall, pulled the lint with agitation tools under negative pressure, and replaced the crushed section with rigid duct through attic access - no drywall repair needed. If the chase is blocked or too narrow, we’ll tell you in the written estimate before any cutting happens.
NADCA recommends annual inspection and cleaning as needed; for Sterling’s 25-35-year-old flex runs, we typically recommend cleaning every 12-18 months depending on household size and dryer use. Homes with multiple loads per week, or with the long second-floor runs common in Potomac Falls and Broad Run Farms, tend toward the shorter interval. After our first visit, we note your specific run condition and recommend a schedule based on what the camera actually showed - not a generic calendar reminder. Call (240) 771-1508 to schedule.
