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 Gaithersburg
Dryer vent cleaning in Gaithersburg typically runs $180-$340 for a standard single-family home, and every job starts with a written price before any work begins. We’re the Gaithersburg crew from CleanRun Air Duct Cleaning Rockville, dispatching from our Washington, DC office to homes across 20877, 20878, 20879, and 20886. Our technicians know the difference between a Montgomery Village colonial with a 22-foot vertical wall-chase vent and a Kentlands neo-traditional with a short through-wall termination - because getting that wrong means leaving lint behind or recommending replacement when cleaning would have sufficed. Call (240) 255-4519 and a live person will answer, 24/7.
Why CleanRun Air Duct Cleaning Rockville Is Gaithersburg’s Preferred Dryer Vent Cleaning Company
We’ve served Gaithersburg homeowners since our first documented job here in 2013, and the photo records from those early calls still sit in our archive - every duct run, every lint deposit, every crushed bird guard at a Montgomery Village roof cap. Our 365-Day Done Right Promise applies in full on every Gaithersburg job, backed in writing, not as a policy subject to manager approval.
Our Gaithersburg customers return because we show them what we found before we quote a price. The camera doesn’t lie. A 3-inch lint compaction at the first elbow of a Centerway Road wall-chase looks the same on our screen as it will in the photo record we deliver before the truck leaves.
Haven Standard Clause 3: Verified Crews means every technician is background-checked, uniformed, and identified by name before arrival. No exceptions. Our equipment roster includes Nikro negative-pressure units and Rotobrush agitation systems - brands you can look up independently before agreeing to any price.
Our Dryer Vent Cleaning Services in Gaithersburg

Dryer Vent Inspection
Every Gaithersburg inspection begins with a camera run from termination to lint trap connection. In Montgomery Village’s 1966-1985 colonials and split-levels, that camera travels 20+ vertical feet through interior wall chases the homeowner has never seen - and we document every frame. Post-storm inspections get particular attention: Seneca Creek’s low-lying humidity pockets drive moisture into duct systems, and we need to distinguish degraded fiberglass duct liner that must be replaced from surface lint that can be extracted. Our inspection report includes timestamped photos, a written scope of work, and - when water intrusion is present - documentation structured so an insurer can separate cleanable vent duct from contaminated duct board.

Vent Cleaning
We clean using negative-pressure extraction (a vacuum system that pulls debris out while agitation tools loosen it from duct walls) combined with rotary brushes sized to the duct diameter. For Montgomery Village’s long vertical chases, we set up negative pressure at the roof termination and run tools down from above - cleaning from the laundry room alone never reaches the compaction that forms in the upper run. A Montgomery Village homeowner on Centerway Road called after her dryer tripped its thermal fuse twice in a week; camera inspection showed a 22-foot vertical wall-chase run packed with compacted lint and a crushed bird guard at the roof cap. We set up negative pressure at the termination using our Nikro unit, ran agitation tools down the chase, and pulled out roughly two gallons of lint - then documented the before/after with photos because the same flood-affected home had water staining in the return duct near the air handler. We flagged the duct board as replace-not-clean and delivered a report the homeowner’s insurer used to separate the vent remediation from the duct replacement claim.

Lint Removal
Lint in Gaithersburg vents isn’t generic fluff. Montgomery Village’s aging flex duct and original fiberglass liner shed particulate that compacts with humidity into dense, fire-risk deposits. Kentlands and Lakelands homes face different lint geometry: shorter runs, tighter bends, and more frequent transitions between rigid and flex sections where lint bridges form. We measure what we remove. The photo record shows the volume and character of the debris - not to embarrass the homeowner, but to document that the work happened and that the vent path is now clear per manufacturer specifications.

Vent Rerouting
Some Gaithersburg vents were routed wrong from construction. A roof-terminated wall chase in a home with a slab-on-grade foundation forces the dryer to push against gravity the entire length of the run. In other cases, a vent terminates under a deck or too close to a window, violating current code. We reroute to shorter, straighter paths where structurally feasible - always with a written price before cutting any wall, always with photos of the old and new configurations for the job record.

AfterTrusted Brands We Service in Gaithersburg
Our Dryer Vent Cleaning crews run professional-grade equipment from Nikro, Honeywell, and Abatement Technologies - brands recognized in the HVAC trade for negative-pressure extraction, moisture measurement, and particulate containment. We stock replacement bird guards and vent caps sized to Gaithersburg’s common termination types, including the 4-inch galvanized caps standard on Montgomery Village’s original construction and the wider-mouth caps used in Kentlands’ later builds. Parts on the truck mean no waiting for a second visit to complete a repair.
Common Dryer Vent Cleaning Problems We See in Gaithersburg Homes

- Roof-terminated wall-chase vents “cleaned” from the laundry room only. Agitation never reaches the vertical run. The lint compacts further up, and storm-driven moisture from Seneca Creek humidity pockets sits undisturbed. We clean from the termination downward, with camera verification at both ends.
- Post-flood calls that conflate wet dryer vent ducting with wet supply/return ducts. A crew cleans the vent but leaves saturated fiberglass duct liner and duct board shedding particulate. The insurer later refuses coverage without contamination documentation. We inspect both systems, photograph the damage, and specify replace-versus-clean in writing.
- Original 1970s bird guards and plastic vent caps crushed or rusted by humidity. Cleared of lint but not replaced, they leave gaps that admit rain - exactly the water intrusion that turns a clean-and-keep call into a replace call. We stock replacements and install them as part of the scope when needed.
- Degraded fiberglass duct liner in Montgomery Village’s 1970s-era two-story colonials. Furnace closet designs trapped humidity against duct board for decades. The liner sheds into the airstream after any water intrusion. Camera inspection finds it. We document it. We flag replacement, not cleaning, and deliver the evidence in insurer-compatible format.
Pricing for Dryer Vent Cleaning in Gaithersburg, MD
A standard dryer vent cleaning in Gaithersburg runs $180-$240 for a single-story through-wall termination, and $260-$340 for a multi-story or roof-terminated wall chase where extended access and camera work are required. Bird guard or vent cap replacement adds $45-$85 per unit, parts and labor included. Vent rerouting, when structurally feasible, is quoted individually after inspection - typically $400-$700 depending on path length and wall access.
What moves the price: the length and geometry of the run, the condition of existing terminations, and whether post-storm inspection reveals water-damaged duct board that requires replacement documentation for insurance purposes. Every price is written before work starts, every time, under Haven Standard Clause 1. No per-vent pricing. No coupon that balloons once the van is in the driveway.

FAQs - Dryer Vent Cleaning in Gaithersburg

Replacement is required when the camera shows degraded fiberglass duct liner, water-stained duct board, or mold colonization inside the duct walls - conditions that cleaning cannot restore to safe function. Cleaning suffices when lint and surface moisture are present but the duct material itself is intact. We document both conditions with timestamped photos and a written scope specifying replace-versus-clean, formatted so your insurer can process the distinction. Call (240) 255-4519 for a post-storm inspection - estimates are free.
Montgomery Village’s 1966-1985 homes were built with 20+ foot vertical wall-chase vents that compact lint out of sight, and with original flex duct and fiberglass liner that degrades and restricts airflow over decades. The combination of restricted airflow and aged, heat-stressed materials creates ignition risk that newer, shorter vent configurations don’t face. Our inspections measure airflow before and after cleaning - documented in the photo record - to verify that the vent performs to manufacturer specification.
No. Kentlands and Lakelands homes from the late 1980s-2000s typically have shorter through-wall or soffit-terminated runs with tighter bends and more flex-to-rigid transitions. The tools and access methods differ. Montgomery Village’s long vertical chases require roof-termination setup and extended agitation runs. We size the approach to the geometry, and we photograph the configuration before quoting so you see why the method matches the house.
A camera run from termination to lint trap connection, airflow measurement at the dryer connection, visual assessment of the termination cap and bird guard, and moisture readings if water intrusion is suspected. You receive timestamped photos of every stage, a written scope of recommended work, and - for post-storm calls - documentation structured for insurance submission. Haven Standard Clause 1 requires the written price before any of that work begins.
Yes. We stock replacement caps and bird guards sized to Gaithersburg’s common termination types, including 4-inch galvanized caps for Montgomery Village originals and wider-mouth caps for Kentlands-era construction. Installation is included in the quoted scope when replacement is needed - not sold as an add-on after the work starts. Every installation is photographed for the job record.
