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.

Our Dryer Vent Cleaning Services in Rockville
Dryer Vent Inspection
A proper inspection in Rockville starts with the duct layout, not the dryer. In Twinbrook’s original 1950s cape cods, the vent run is typically a long, back-to-back galvanized rigid pipe that dumps at the foundation wall, far from the laundry corner, with the first elbows packed solid behind the sheet-metal stub the homeowner can reach. That long, multi-elbow layout is rare in King Farm’s 2000s townhomes, where short flex runs behind the dryer aren’t the same cleaning problem. Our inspection uses a camera to map the full run, locate elbows, check for disconnected segments in crawl spaces, and identify missing or failed caps. We deliver the findings in writing with photos before quoting any cleaning work.
Vent Cleaning
Our Dryer Vent Cleaning process varies by what we find. Original Twinbrook galvanized runs with multiple elbows require agitation tools and a Rotobrush whip head on a flexible rod, run from the exterior cap inward, to break compacted lint at the elbows where suction alone won’t reach. For King Farm flex-duct systems, we use negative-pressure extraction with a Nikro HEPA collector to prevent lint release inside the home. Every cleaning concludes with airflow measurement at the exterior cap to verify restored performance. The photo record shows every stage.
Lint Removal
Lint in Rockville’s older homes is rarely loose and fluffy. In Twinbrook and East Rockville properties where vent runs pass through uninsulated crawl spaces without vapor barriers, summer condensation wets the lint and it sets into a hard felted plug. A shop-vac pass at the outside cap misses the worst of it. We use mechanical agitation to break these plugs, then extract under negative pressure so debris never enters the laundry room or living space. The camera confirms the run is clear before we pack up.
Vent Rerouting
Some Rockville homes have dryer vent runs that were never optimal. We’ve found Twinbrook cape cods where the original installer routed the vent through an unconditioned attic space, or where a previous renovation left the run with three 90-degree elbows when two would suffice. Excessive elbows, long horizontal runs, and terminations that trap moisture all accelerate lint buildup and create fire risk. When rerouting is the right fix, we quote it as a separate line item with a written price and scope, not as an upsell discovered mid-job.
Vent Cap Replacement
Rockville’s 2000s King Farm flex-duct installs often terminate in a flapper cap that won’t seat after a few years. Without a bird guard or a new cap, squirrels and starlings nest in the lint pathway, and we find nesting material behind the flap on the first visit. We stock Guardsman replacement caps and bird guards for same-day installation, and we photograph the old cap condition and the new installation as part of the standard job record.
Bird Guard Installation
Missing bird guards are a recurring find in Rockville, particularly on homes where the original cap was damaged or never included one. A proper bird guard prevents nesting while maintaining airflow. We measure the existing termination and install a compatible Guardsman guard, photographed before and after as standard.

Common Dryer Vent Cleaning Problems We See in Rockville Homes
- Original Twinbrook galvanized runs with packed elbows. The first elbow closest to the dryer and the section behind the wall stub accumulate the most lint, but they’re inaccessible from the exterior cap. A camera inspection locates the blockage, and agitation tools break it for extraction.
- Condensation-wetted lint plugs in uninsulated crawl spaces. Rockville’s humid summers produce heavy condensation on duct exteriors in homes without vapor barriers. Wet lint hardens into a felted mass that requires mechanical agitation, not suction alone.
- Failed flapper caps and missing bird guards in King Farm townhomes. The original plastic flapper loses tension after several seasons, and without a bird guard, the vent becomes entry point for nesting animals. We find leaves, twigs, and compacted nesting material mixed with lint.
- Disconnected or crushed flex runs behind the dryer. In tighter laundry closets common in Rockville’s townhomes, the flex duct gets kinked when the dryer is pushed back, or the connection loosens over time. The inspection catches this before cleaning begins.
Pricing for Dryer Vent Cleaning in Rockville, MD
A standard dryer vent cleaning in Rockville runs $180-$240 for a single straight run up to 15 feet, $260-$340 for systems with multiple elbows, long rigid runs, or crawl-space access requirements. Vent cap replacement adds $45-$85 depending on the Guardsman model. Bird guard installation is $35-$65. Rerouting or significant repair is quoted separately after inspection, with a written scope and price before any work starts.
What moves the price: duct material (galvanized rigid vs. flex), number of elbows, accessibility (crawl space vs. interior wall), and whether the cap or guard needs replacement. We don’t do per-vent pricing or teaser coupons. Every Rockville customer receives one flat price per system, agreed in writing under Haven Standard Clause 1, before a single panel comes off.

FAQs - Dryer Vent Cleaning in Rockville
Original galvanized rigid pipe can almost always be cleaned if it’s intact and properly connected. We camera the full run first to check for rust-through, disconnected joints in the crawl space, or crushing at elbows. If the metal is sound, agitation cleaning restores airflow and we document the condition in photos. Replacement is only quoted when the inspection shows structural failure. Call (571) 520-6317 to schedule an inspection with a written price before any work starts.
The long, multi-elbow galvanized runs in 1950s cape cods create more friction points and slower airflow than the short flex runs in 2000s townhomes. Slower airflow drops more lint at each elbow, and the uninsulated crawl spaces common in Twinbrook add condensation that hardens the lint into plugs. King Farm’s shorter runs and better-insulated spaces don’t accumulate at the same rate. Both need cleaning, but the older homes typically need it more often and require more intensive agitation to clear.
We use negative-pressure extraction with a sealed connection at the vent or the dryer junction, so lint and debris are drawn directly into the HEPA collector rather than released into the laundry room. For interior-access jobs, we isolate the work area and run the extraction continuously during agitation. The photo record shows the sealed setup. This is standard on every CleanRun job, not an add-on.
No. Dryer vent cleaning addresses the exhaust duct that carries lint and hot air from your dryer to the exterior. Air Duct Cleaning - Rockville addresses the supply and return ducts of your HVAC system that heat and cool your home. They’re separate systems with separate access points, equipment, and safety considerations. Some Rockville homeowners schedule both, but they’re quoted as distinct services with separate written prices. We don’t bundle them without explicit customer request.
The inspection checks five things: the full duct layout and material, the location and condition of all elbows and joints, airflow volume at the exterior cap, the termination cap and bird guard condition, and any signs of moisture damage or animal entry. In Rockville’s older homes, we specifically look for disconnected segments in crawl spaces and rust at galvanized joints. You receive the findings in writing with photos, and the cleaning quote is based on what we actually found, not a flat rate that ignores your duct layout. Call (571) 520-6317 to book.
