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 Gaithersburg
Dryer vent cleaning in Gaithersburg typically runs $180-$340 for a standard single-family or townhome system, with vent rerouting or rigid-pipe replacement adding $200-$450 when original builder-grade flex has failed. Most jobs are completed in 90 minutes to two hours, and every one starts with a written price before a tool comes out of the truck.
We know Gaithersburg’s homes. Our crews work the planned communities of Kentlands and Lakelands, the mid-century stock near Olde Towne, and the newer developments off Route 355 and I-270. Dispatch and scheduling are coordinated from our Washington, DC office, but the technicians who arrive at your door live and work in Montgomery County. They understand how Gaithersburg’s 70°F summer dew points and heavy oak pollen load interact with vent systems that run through unconditioned attic knee walls.

Our Dryer Vent Cleaning Services in Gaithersburg
Dryer Vent Inspection
Every Gaithersburg job starts here. We run a camera through the full vent pathway - from the dryer’s transition duct to the exterior termination cap - and show you what we see. In Kentlands and Lakelands townhomes, we regularly find micro-tears at elbow joints where 25 years of thermal expansion has stressed the outer jacket of original flex duct. The camera doesn’t lie. We document the findings, explain the options, and deliver a written price before any work begins - Haven Standard Clause 1.
Vent Cleaning (Lint Removal)
We use negative-pressure extraction (a high-suction vacuum system that pulls debris out rather than blowing it inward) combined with rotary brushing to dislodge packed lint. For Gaithersburg’s older homes near Olde Towne, where dryer vents may have been retrofitted through tight, awkward chases in 1940s-1970s framing, this approach matters. There’s no room for error in a 6-inch chase with plaster lath on one side and a bearing wall on the other. Our Dryer Vent Cleaning teams carry Rotobrush and Nikro equipment sized for these constraints.
Vent Rerouting
This is where our Gaithersburg work gets specific. Kentlands and Lakelands townhomes - built between the late 1980s and early 2000s - are now hitting the 20-to-35-year mark where builder-grade flex duct and dryer vent runs alike show micro-tears at elbow joints, letting attic insulation and dust straight into the airstream. When we open these chases, a dryer vent cleaning bid regularly turns into vent rerouting and upgraded rigid pipe because the original corrugated aluminum has essentially failed. We replace the damaged section with smooth rigid metal, seal all joints with foil tape (not screws, which catch lint), and install a proper termination cap. Written price before we start. Photos after we finish.
Bird Guard Installation & Vent Cap Replacement
Gaithersburg’s dense residential tree canopy - heavy oak and maple - supports a robust bird and rodent population. Cramped utility chases and knee-wall terminations in planned-community townhomes are prime entry points. We install Guardsman vent caps with integrated bird guards and backdraft dampers, and we document the installation in your photo record. If your existing cap is missing its flapper or screen, we’ll show you why that matters.

BeforeAfterTrusted Brands We Service in Gaithersburg
Our equipment roster includes Rotobrush camera inspection systems, Nikro negative-pressure extractors, and Guardsman termination hardware - brands you can look up independently before agreeing to any work. We don’t use shop vacs with duct tape adapters. For Gaithersburg customers, this means parts and replacement caps are available without multi-day ordering delays. If your Kentlands townhome needs a Guardsman bird guard or a rigid-pipe elbow that matches the existing run, we typically stock it.
Common Dryer Vent Cleaning Problems We See in Gaithersburg Homes
- Crushed corrugated flex at knee walls. Kentlands and Lakelands townhomes were built with dryer vent runs through unconditioned attic knee walls. Twenty-five years of thermal cycling has collapsed the flex at joist penetrations. The dryer works harder, dry times stretch past 45 minutes, and the homeowner assumes the appliance is failing.
- Insulation fibers in the airstream. Micro-tears in aging flex duct pull fiberglass attic insulation into the vent pathway. Homeowners blame Montgomery County’s heavy pollen load for allergy symptoms. Camera inspection separates the two.
- Failed vent termination caps. Original caps on cramped utility chases lost their screens or flappers years ago. Birds and rodents enter, build nests, and block exhaust flow. Backdrafting becomes a real risk.
- Disconnected runs in retrofitted older homes. Near Olde Towne, 1950s-1970s homes with forced-air retrofits often have dryer vents cobbled through tight chases. We’ve found runs separated at couplings, blowing lint into wall cavities for years.
Pricing for Dryer Vent Cleaning in Gaithersburg, MD
A standard dryer vent cleaning in Gaithersburg - single-family or townhome, one dryer, accessible termination - runs $180-$240. This includes full camera inspection, rotary brushing, negative-pressure extraction, and the Documented Photo Record.
Vent rerouting with rigid-pipe replacement, when original flex has failed, adds $200-$450 depending on linear feet and chase access. Bird guard or vent cap replacement is typically $85-$150 per cap, including hardware and installation.
What affects cost: length of run, number of elbows, accessibility (crawl space vs. finished basement), and whether we find failed flex that needs replacement. We don’t do per-vent pricing or $79 teaser coupons. One flat price per system, agreed in writing before work starts. Free estimates. Call (240) 363-3380.

FAQs - Dryer Vent Cleaning in Gaithersburg
Your original corrugated aluminum flex vent run has likely collapsed or developed micro-tears at elbow joints after 25-plus years of thermal expansion. We find this in Kentlands and Lakelands townhomes regularly. The vent is partially blocked, or leaking into the chase, or both. Camera inspection confirms the failure point. Call (240) 363-3380 for a free written estimate.
Yes. Dryer vent cleaning addresses the exhaust pathway from your dryer to the exterior cap - metal or flex duct that carries hot, moist air and lint. Air Duct Cleaning in Gaithersburg addresses the supply and return ductwork that moves conditioned air throughout your home. In Gaithersburg’s planned communities, we often find both systems failing simultaneously in the same attic knee walls, but they require different equipment and different access points. We price them separately and document each system independently.
Every 12-18 months for typical residential use. Gaithersburg’s heavy tree canopy produces more airborne debris than arid climates, and homes with multiple laundry loads per week accumulate lint faster. If your dryer is taking longer than 35 minutes per load, or if the exterior cap shows no airflow when the dryer runs, schedule inspection regardless of calendar.
Usually not for cleaning alone. Most Gaithersburg dryer vents can be accessed at the dryer connection, at termination points, or through existing utility chases. If we find failed flex that requires rerouting with rigid pipe, we may need limited attic or chase access. We show you the camera evidence, explain exactly what access is needed, and agree to a written price before any cutting occurs.
Probably not directly, but the same housing era causes both problems. Kentlands and Lakelands townhomes built in the 1990s-2000s have original flex ductwork - both HVAC and dryer vent - now failing at elbow joints. Attic insulation fibers enter the HVAC airstream, while the dryer vent leaks moisture and lint into wall cavities. Homeowners blame pollen because that’s visible. Camera inspection of both systems separates the actual contamination sources. We’ve documented this pattern in dozens of Gaithersburg homes.
