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.
Fast, Reliable Dryer Vent Cleaning Across Rockville
Dryer vent cleaning in Rockville typically runs $180-$340 for a standard single-family home, with most jobs completed in 90 minutes to two hours. Our crews are dispatched from our Washington, DC scheduling office and carry equipment for Rockville’s specific housing stock - from Twinbrook’s 1950s Cape Cods to the planned communities of King Farm. Call (240) 318-7712 and we’ll put a written price in front of you before any work starts.
We’ve been serving Montgomery County since 2013, and Rockville’s mix of retrofit-era ranchers, aging split-levels, and newer construction means no two vent runs are the same. The lint-packed elbow in a Twinbrook knee-wall attic is a different job entirely from the straight through-wall run in a 2015 Fallsgrove townhouse. Our technicians arrive with the tools for both.
Why CleanRun Air Duct Cleaning Alexandria Is Rockville’s Preferred Dryer Vent Cleaning Company
Rockville homeowners have left us documented reviews describing what they found in their vents - and what they received from us. The pattern is consistent: they mention the written price delivered before work started, the before-and-after photos they could scroll through on their phones, and the technician who explained why their specific vent run failed. Haven Standard Clause 1, Written Price Before Work Starts, applies on every Rockville job, not just the easy ones.
Our response time to Rockville neighborhoods is typically same-week, with scheduling coordinated from our Washington, DC office. We know the difference between Fallsmead’s 1970s colonials and the newer King Farm builds, and we stock vent caps and flex duct sized for both. Background-checked, uniformed technicians operating under Haven Standard Clause 3, Verified Crews, arrive identified by name.
The 365-Day Done Right Promise backs every Rockville job in writing. If the dry time doesn’t improve or the vent path blocks again, we make it right. That promise has been in force since our first job in 2013, and it is not subject to manager approval.
Tomas Reyes, who leads CleanRun, established the Documented Photo Record practice from day one: every vent run photographed before and after, delivered to the customer as part of the standard job record. Rockville customers can verify what was done without relying on a verbal report.
Our Dryer Vent Cleaning Services in Rockville

Dryer Vent Inspection
Every Rockville job starts here. We run a camera through the full lint pathway and photograph what we find. In Twinbrook’s 1950s Cape Cods, that pathway often runs 20-plus feet through unheated knee-wall attics with multiple elbows - far longer than the straight 8-10 foot runs typical of newer Rockville construction. The camera reveals kinked flex, crushed sections, and lint density that visual inspection from the laundry room cannot predict. You receive these photos before we quote any cleaning or repair work. Haven Standard Clause 1 requires the written price before work starts; the inspection provides the factual basis for that price.

Vent Cleaning and Lint Removal
We use negative-pressure extraction - suction applied to the vent line while agitation tools loosen adhered lint - combined with HEPA filtration to contain what we remove. Rockville’s humid summers complicate this work. July and August dewpoints in the low-to-mid 70s°F keep lint pathways damp and sticky, accelerating buildup and binding lint to duct walls more tightly than in drier climates. The 1970s-80s split-levels in Fallsmead and Hungerford present an additional challenge: aging fiberglass duct board sheds fibers that mix with lint, making source removal harder and requiring careful containment. Our crews use Rotobrush and Nikro equipment sized for these conditions.

Vent Rerouting
Some Rockville vent runs are beyond cleaning. In Twinbrook retrofits, flex duct routed through knee-wall attics in the 1960s and 1970s has kinked or partially collapsed at elbows after decades of thermal cycling and physical disturbance. Straightening the lint pathway - often by rerouting the run to eliminate sagging sections and reduce elbow count - is the durable fix. We document the old route and the new one with photos, and the written scope specifies materials (typically rigid or semi-rigid metal duct, not foil flex) and the new path. Rerouting in Rockville typically adds $120-$280 to the base cleaning price depending on attic access and length.

Vent Cap Replacement and Bird Guard Installation
Original vent caps on Rockville’s older homes are often missing louvers, cracked, or absent entirely - an open invitation for birds, squirrels, and moisture intrusion. We stock replacement caps and bird guards sized for 4-inch duct, the standard for residential dryers. Installation includes sealing the wall or roof penetration and photographing the finished work. Bird guards use a mesh screen that blocks nesting material while maintaining airflow; we clean these annually as part of maintenance plans. A new cap or guard in Rockville runs $85-$150 installed, depending on roof-line access.

Common Dryer Vent Cleaning Problems We See in Rockville Homes

- Kinked knee-wall runs in Twinbrook retrofits. The 1960s-70s forced-air retrofits routed dryer vents through attic spaces never designed for them. Decades later, flex duct has kinked at elbows or sagged into traps where lint accumulates beyond the reach of standard brushing. Our camera inspection finds these before we quote.
- Fiberglass duct board degradation in 1970s-80s Fallsmead and Hungerford splits. Original duct board sheds fibers that mix with lint, creating a dense, adhered mat. HEPA containment and aggressive agitation are required; without them, cleaning spreads debris into the living space.
- Humid summer lint adhesion. Rockville’s July and August dewpoints keep vent interiors damp. Lint sticks to metal and flex surfaces more tenaciously than in arid climates, requiring longer agitation cycles and more thorough post-cleaning verification.
- Missing or failed vent caps. Open penetrations allow bird nesting, water intrusion, and backdraft. We replace these with screened caps or bird guards as part of the standard scope when needed.
Pricing for Dryer Vent Cleaning in Rockville, MD
A standard dryer vent cleaning in Rockville runs $180-$240 for a single-family home with accessible through-wall venting. Homes with attic-routed runs - typical of Twinbrook Cape Cods and ranchers - run $240-$340 due to additional access time and the likelihood of finding kinked or crushed sections requiring correction. Vent rerouting adds $120-$280. Vent cap or bird guard replacement adds $85-$150.

FAQs - Dryer Vent Cleaning in Rockville

Every 12-18 months, and annually if you dry heavy loads frequently. The 20-plus-foot runs with multiple elbows common in Twinbrook retrofits accumulate lint faster than straight through-wall vents, and the knee-wall attic path is harder to inspect from the laundry room. Call (240) 318-7712 to schedule an inspection and we’ll put a written maintenance interval in your job record based on what the camera shows.
Restricted airflow from lint buildup, duct board fiber accumulation, or a partially blocked vent cap is the typical cause. Fallsmead’s 1970s-80s split-levels often contain original fiberglass duct board that has degraded and shed fiber into the airstream, combining with lint to form dense blockages. Our camera inspection identifies which failure mode is present before we quote cleaning or repair. Call (240) 318-7712 for a free estimate.
Only if the vent runs through it - which is common in Twinbrook’s retrofitted Cape Cods and ranchers. We photograph the attic path during inspection so you see why access is necessary. For through-wall vents in newer Rockville construction, attic entry is rarely required. The written scope specifies every access point before work starts.
Yes, by preventing the blockages that cause repeat service calls. Bird guards block nesting material; new caps with functioning louvers keep out rain and wind-driven debris. In Rockville’s tree-heavy neighborhoods, falling leaves and seeds also enter open caps. We include cap condition in every inspection and recommend replacement when the original is cracked, missing louvers, or absent. The installed price is $85-$150.
It makes buildup stickier and harder to remove, which means summer-cleaned vents stay clear longer than those cleaned in dry conditions. The low-to-mid 70s°F dewpoints in July and August create damp lint that adheres to duct walls; if left through multiple seasons, this material hardens and requires more aggressive removal. Post-summer cleaning is a concrete local practice we recommend for Rockville’s climate.
