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 serve Bethesda from our Washington, DC dispatch office, with crews covering Edgemoor, Kenwood, the Bradley Boulevard corridor, and neighborhoods west toward Cabin John daily. Our technicians know the local housing stock: the 1950s Cape Cods with attic knee-wall duct runs, the expanded split-levels with spliced vent lines from three-decade-old kitchen renovations, and the newer teardown rebuilds where construction debris still circulates through adjacent homes’ systems. That local familiarity means we arrive with the right equipment and the right expectations, not a generic checklist.
Why CleanRun Air Duct Cleaning Rockville Is Bethesda’s Preferred Dryer Vent Cleaning Company
Bethesda homeowners are unusually exacting about documentation, and that suits how we work. Our Dryer Vent Cleaning team has built its reputation here on deliverables you can verify: a written price before any panel comes off, camera footage of every vent run before and after, and a 365-Day Done Right Promise backed in writing on every job. Haven Standard Clause 1 requires it.
Our client base in the NIH corridor - research scientists, physicians, and federal health-agency staff - routinely asks for particle-count readings, third-party air-quality verification, and documentation of what was actually removed. We don’t lose those jobs because we produce the record. Every visit includes a Documented Photo Record of the inside of every duct run, delivered as part of the standard job file. That’s been our practice since 2013, across 52,000+ homes.
Crews are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. The license number is published on this page, not buried in a footer. Equipment includes Nikro negative-pressure extractors and Honeywell HEPA filtration - brands you can look up independently before agreeing to any price.
Our Dryer Vent Cleaning Services in Bethesda
Dryer Vent Inspection
Every job starts here. We run a push camera through the full vent run, from the back of the dryer to the exterior cap, documenting what we find before recommending any work. In Bethesda’s 1945-1970 housing stock, we regularly see flex-duct splices hidden behind finished basement ceilings, crushed elbows from kitchen renovations, and post-construction debris from neighboring teardowns in Edgemoor or Kenwood that has infiltrated the run. The inspection takes 20-30 minutes and comes with a written scope and price before any cleaning begins.
Vent Cleaning
We clean using agitation tools and negative-pressure extraction, not a shop vac and a prayer. For Bethesda’s longer runs - common in expanded Colonials and split-levels with rear additions - we use Rotobrush mechanical agitation to break up compacted lint at elbows and transitions, then pull it under controlled vacuum with HEPA filtration so nothing recirculates into your home. The process is documented with before-and-after camera footage for every section.
Lint Removal
Lint compaction is the routine failure mode, but Bethesda presents a second: fine construction particulate. When a neighboring home is gutted on the 7000 block of Bradley Boulevard or along Dorset Avenue, drywall dust and spray-foam insulation fibers pull into adjacent vent runs through building envelope gaps. Standard lint removal won’t touch this material. We identify it during camera inspection, then use targeted agitation and high-volume extraction to remove it. The difference shows in the photo record.
Vent Rerouting
Some Bethesda homes need more than cleaning. Decades of piecemeal additions left convoluted runs with multiple splices, excessive elbows, or duct routed through unconditioned attic spaces where July humidity above 70% keeps surfaces near the dew point. We reroute to shorten the run, eliminate unnecessary transitions, and improve airflow. Every reroute includes a written scope, material specification, and documentation of airflow improvement measured at the exterior cap.

Our equipment roster includes Nikro negative-pressure extractors, Honeywell HEPA filtration systems, and Guardsman vent caps with integrated bird guards - the same hardware we specify for Bethesda’s tree-canopied neighborhoods where starlings and squirrels routinely nest in uncapped terminations. We stock Guardsman caps and Aprilaire filtration accessories locally, so replacements don’t delay completion. You can verify every brand independently before we start.
Common Dryer Vent Cleaning Problems We See in Bethesda Homes
- Post-construction contamination from neighboring teardowns. In Edgemoor, Kenwood, and along the Bradley Boulevard corridor, demolition and luxury reconstruction are nearly constant. Drywall particulate, spray-foam insulation fibers, and construction dust infiltrate adjacent homes’ dryer vent runs through shared return-air pathways and building envelope gaps. Standard lint removal won’t address the fine coating on duct walls.
- Long, convoluted runs in expanded homes. Bethesda’s 1945-1970 housing stock has often been added onto multiple times, leaving mismatched duct sections, flex-duct splices, and disconnected runs that surface-level cleaning misses. Without a full camera inspection, compacted lint at hidden elbows goes undisturbed.
- High humidity and mold colonization in attic runs. With July relative humidity routinely above 70%, vent runs through unconditioned attic spaces stay near the dew point. Fiberglass-lined or flex duct surfaces can support mold growth that requires source removal and documentation, not just a visual sign-off.
- Crushed or improperly supported flex duct from renovations. A 1960s split-level with a newer rear addition often has the original 4-inch flex duct spliced into a longer rigid run during a kitchen renovation, creating a lint pathway with a crushed elbow behind new cabinetry. We found exactly this on Bradley Boulevard: the dryer was taking two cycles to dry a load. Our tech isolated the section, used agitation tools to break up compacted lint, pulled it under negative pressure with HEPA filtration, and installed a new Guardsman vent cap with bird guard. The dryer cycle dropped back to normal. We documented before-and-after camera footage for the homeowner’s records.

What moves a job toward the higher end: length of run, number of transitions, accessibility (finished basement ceilings, attic knee-walls), and whether post-construction debris requires extended agitation. What doesn’t affect price: the neighborhood. We don’t charge Edgemoor more than Westbard for the same scope.
Every price is written and agreed before work starts - Haven Standard Clause 1. No exceptions. Bring a competitor’s written estimate; we’ll deliver a Free Second Opinion with our number next to it.

FAQs - Dryer Vent Cleaning in Bethesda
Bethesda’s teardown-and-rebuild cycle generates construction dust that neighboring homes’ vents pull in through building envelope gaps, and the humid subtropical climate here keeps attic duct surfaces near the dew point, accelerating debris adhesion. Rockville and Gaithersburg see less of both. Most Bethesda homes with active nearby construction benefit from inspection every 12-18 months rather than the standard 2-year interval. Call (240) 255-4519 to schedule - estimates are free.
We price per system, not per visit, because each vent run is a separate scope with its own camera inspection, agitation, extraction, and documentation. A home with laundry on the main floor, in a basement apartment, and in an au-pair suite above the garage requires three complete job records, three photo sets, and three written prices agreed before any work begins. The total is simply the sum; there’s no “volume discount” because there’s no volume shortcut in the work.
You’ll receive a written scope of work performed, before-and-after camera footage of every vent run, a 365-Day Done Right Promise in writing, and if requested, particle-count or airflow measurements at the exterior cap. This is standard on every job, not an upgrade. NIH-area clients often request additional third-party air-quality testing; we coordinate that and include our pre/post readings in the package.
Yes. When a home in Edgemoor or Kenwood is demolished or gutted, the negative pressure and envelope disturbance pull drywall dust, spray-foam fibers, and particulate into adjacent duct systems through gaps that existed since original construction. Standard lint removal won’t clear this material. We identify it during camera inspection and use targeted agitation with high-volume extraction. The photo record shows the difference. If your neighbor has a permit posted, consider a preventive inspection.
Yes. Our technicians follow NADCA ACR and dryer vent cleaning protocols, and we field regular requests from Bethesda’s NIH corridor clients for NADCA-certified work specifically. We don’t claim certifications we can’t produce on request; our credentials are available for verification before any price is agreed. If your housing authority, insurance, or health agency requires NADCA-compliant documentation, we deliver it as part of the standard job record.
