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.

AfterFast, Reliable Dryer Vent Cleaning Across Rockville
Dryer vent cleaning in Rockville typically runs $180-$340 for a standard single-family home, and every job starts with a written price before we touch a single panel. If your dryer is taking two cycles to finish a load, the problem is almost always the vent pathway, not the appliance itself. Call us at (240) 363-3380 and we’ll put a number in writing before scheduling.
We serve Rockville from our Washington, DC dispatch office, with crews covering Twinbrook, East Rockville, King Farm, Fallsgrove, and the full 20850-20853 corridor. Rockville’s housing stock splits cleanly in two directions: the 1950s ramblers and Cape Cods with original sheet-metal ductwork, and the newer planned communities where construction debris too often gets handed off with the keys. Both fail the same performance test for opposite reasons, and both need different inspection protocols. That’s the work our Dryer Vent Cleaning team has documented since 2013.
Why CleanRun Air Duct Cleaning Washington Is Rockville’s Preferred Dryer Vent Cleaning Company
We’ve completed documented dryer vent jobs in every Rockville neighborhood from Twinbrook Parkway to Fallsgrove Boulevard. Our crews know the difference between a 1954 rambler’s original 4-inch sheet-metal run and a 2019 townhome’s flexible duct terminated through vinyl siding. That local knowledge changes what we bring to the job and what we charge.
Every Rockville customer receives a written price before work starts, a photo record of the inside of every vent run before and after, and the 365-Day Done Right Promise backed in writing on every invoice. Haven Standard Clause 1 is non-negotiable: no estimate delivered verbally, no “call for pricing,” no invoice that exceeds the written scope.
Our technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. The equipment roster includes Rotobrush agitation systems and Abatement Technologies negative-pressure extractors - brands you can verify independently before you agree to any price.
CleanRun has served 52,000+ homes since 2013. Every one with a written price first. Every one with a documented photo record at completion.
Our Dryer Vent Cleaning Services in Rockville
Dryer Vent Inspection
A proper inspection in Rockville means running a camera through the full lint pathway, not just glancing at the exterior cap. In Twinbrook and East Rockville, we routinely find 1950s-era vent runs routed through uninsulated basement or crawl space cavities where summer condensation mixes lint with rust scale and biological growth. The exterior termination can look clear while the interior elbow is packed solid. Our inspection documents every foot with photographs, delivered to you as part of the standard job record. King Farm and Fallsgrove inspections focus on a different failure mode: construction dust, drywall debris, and missing or incorrect vent caps from handover that restrict airflow from day one.
Vent Cleaning and Lint Removal
We perform source removal using agitation tools under negative-pressure extraction (a contained vacuum system that pulls debris out of your home rather than redistributing it). A standard shop-vac-only cleaning on a long Twinbrook crawl-space vent without camera verification often leaves compacted lint against a rusted elbow. That’s not a theoretical risk. In 2023 we were called to a 1954 rambler off Twinbrook Parkway where the homeowner had already replaced the dryer and the blower motor. A camera inspection showed the original 4-inch sheet-metal run had a crushed elbow behind the foundation wall and a bird guard packed solid with oak-and-maple seed fluff. After source removal with agitation tools under negative pressure and a new vent cap, the dryer cycle dropped back to normal. The homeowner scheduled a full supply and return duct cleaning for the same visit.
Vent Rerouting
Some Rockville homes, particularly basement laundry setups in older ramblers, have dryer vents that terminate into crawl spaces or unfinished basements rather than to the exterior. This violates current Montgomery County mechanical code and creates a fire hazard and moisture problem simultaneously. We reroute these runs to proper exterior termination, which often requires extending the pathway through a different wall or rim joist. Every reroute job includes a written scope, a before-and-after photo record, and verification of proper termination height and clearance to comply with local requirements.
Vent Cap Replacement and Bird Guard Installation
Rockville’s heavy oak, maple, and cherry pollen season creates a predictable spring surge in vent cap blockages. We stock and install code-compliant vent caps with integrated bird guards for Rockville customers, including models suited to the area’s common siding types. A missing or damaged bird guard is often the entry point for the debris that causes the two-cycle drying problem. We photograph the existing cap, document the replacement, and include both images in your job record.

Common Dryer Vent Cleaning Problems We See in Rockville Homes
- Condensation-compacted lint in 1950s crawl-space runs. Rockville’s Twinbrook and East Rockville ramblers have vent ducts routed through uninsulated cavities where summer humidity above 80% relative humidity condenses on the metal surface. Lint adheres to the wet wall, dries as scale, and builds up in layers that a standard cleaning misses without camera verification and agitation tools.
- Construction debris in new King Farm and Fallsgrove homes. Drywall dust, wood shavings, and occasionally forgotten lunch debris from the build crew sit in the vent run from handover. The dryer works harder from month one, and the homeowner assumes the appliance is underpowered rather than obstructed.
- Crushed or disconnected elbows behind foundation walls. Original 1950s sheet-metal runs in Rockville’s pan-return-adjacent foundations often have elbows that have settled, corroded, or been damaged by later plumbing or electrical work. The dryer still pushes air, but the restricted pathway doubles or triples drying time and overheats the blower motor.
- Missing or failed bird guards after heavy pollen seasons. Rockville’s spring oak-and-maple seed fluff packs into unprotected vent caps, creating a blockage that builds gradually until the dryer fails to dry at all. Annual inspection catches this before the emergency call.
Pricing for Dryer Vent Cleaning in Rockville, MD
A standard dryer vent cleaning in Rockville runs $180-$240 for a single-story home with accessible exterior termination. Two-story runs, crawl-space access requirements, or significant lint compaction typically fall in the $260-$340 range. Vent rerouting jobs start at $400 and are scoped after camera inspection. Vent cap replacement with bird guard installation is $85-$150 when performed as part of a cleaning, or $120-$180 as a standalone visit.
What moves a job to the higher end: length of run exceeding 25 feet, multiple elbows, crawl-space or attic access requiring protective setup, and documented heavy compaction requiring extended agitation time. What does not affect price: the neighborhood you live in, the brand of your dryer, or how long it’s been since the last cleaning. We deliver the written price after inspection and before any work starts. Every time. No exceptions.

FAQs - Dryer Vent Cleaning in Rockville
It’s almost always the vent. In Twinbrook’s 1950s ramblers, we routinely find original 4-inch sheet-metal runs with crushed elbows behind foundation walls or condensation-compacted lint in crawl-space sections that the exterior cap doesn’t reveal. Before you replace a dryer or blower motor, have the vent pathway camera-inspected. The inspection itself is $85-$120, credited toward cleaning if you proceed. Call (240) 363-3380 to schedule.
Yes, frequently. Construction dust, drywall debris, and missing or incorrect vent caps are common handover conditions in Rockville’s newer planned communities. The dryer may function initially because the partial blockage hasn’t yet reached critical mass, but drying times lengthen gradually as lint from normal use layers over the construction debris. We recommend camera inspection before or within the first year of occupancy. The photo record shows you exactly what the builder left behind.
Every 12-18 months for most Rockville homes, with annual inspection strongly recommended for properties with crawl-space or unconditioned-basement vent runs. Rockville’s summer dew points in the low-to-mid 70s°F create condensation conditions that accelerate lint adhesion, and the heavy spring oak-and-maple pollen season contributes organic debris that compacts against existing lint. Homes with multiple pets or heavy laundry volume may need cleaning closer to annually. Call (240) 363-3380 and we’ll put a maintenance schedule in writing based on your specific vent configuration.
A proper cleaning involves camera inspection of the full lint pathway, source removal with agitation tools under negative-pressure extraction, verification of clear airflow with measurement, and replacement of any failed caps or guards. We deliver before-and-after photographs of every foot of the run, a written scope of work performed, and the 365-Day Done Right Promise. What it does not involve: a shop vacuum at the exterior cap, a blower test without visual verification, or any work performed before a written price is agreed upon. Haven Standard Clause 1 applies to every Rockville job.
Yes, and it should be done immediately. Venting into a basement or crawl space violates Montgomery County mechanical code and creates both fire hazard and moisture damage conditions. We reroute to proper exterior termination with code-compliant height and clearance, document the new pathway with photographs, and provide the written scope for your records. Reroutes require camera inspection first to determine the optimal new pathway; inspection is $85-$120, credited toward the reroute job. Call (240) 363-3380 to schedule scoping.
