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.
Guardsman Dryer Vent Cleaning in Ashburn: What to Know First
We provide independent Guardsman dryer vent cleaning in Ashburn, Virginia, with most inspections and cleanings completed in a single scheduled visit. A standard Guardsman dryer vent cleaning runs $189 to $349 depending on duct length, termination type, and whether rerouting is needed. Every job starts with a written price before we touch a tool, and every homeowner receives a documented photo record of what we found inside the vent run.
This page is for Ashburn homeowners who own a Guardsman dryer vent system, whether it’s the original builder installation in a Loudoun Station townhome or a retrofit in a single-family near Ashburn Village. If your dryer’s taking longer than one cycle, your laundry room’s humid, or you’ve noticed the vent cap barely opens when the dryer runs, the vent run is likely obstructed. Call (240) 771-1508 for a free estimate with a written price delivered before any work begins.
How Guardsman Products Fail - and How We Fix Them
- Guardsman GV-Series rigid vent kits: The 90-degree elbows in the GV line use a slightly thinner gauge aluminum than competing builder-grade kits. In Ashburn’s clay-heavy soil, foundation settling over five to seven years often pulls these elbows out of square, creating a lip inside the duct where lint packs. We photograph the separation, then replace with a heavier-gauge elbow or reroute to reduce joint count under Haven Standard Clause 1’s written scope.
- Guardsman flexible transition ducts (GFT models): These corrugated flex lines sag between the dryer and wall penetration, especially in stacked laundry configurations common in Ashburn’s newer townhomes. The corrugation traps lint at the low point; we’ve pulled out compacted deposits exceeding three inches in depth. We replace GFT flex with a smooth-wall rigid transition where code allows, and show the homeowner the before photo first - then we can talk about what happens next.
- Guardsman bird guard assemblies (BG-4 and BG-6): The mesh screens on these guards use a finer weave than competitors, which catches lint more aggressively in homes with pets or high-volume laundry. The symptom is reduced airflow without obvious external blockage. We remove, clean, and either reinstall the OEM screen or substitute a quality aftermarket guard with slightly larger mesh if the homeowner’s lint production is consistently high.
- Guardsman through-wall terminations (TWT-150 series): The damper flapper in these terminations uses a plastic hinge that stiffens in cold weather. Ashburn’s freeze-thaw cycles from December through March cause binding; the flapper stays partially closed, back-pressuring the dryer and extending dry times. We document the binding, replace the termination with a metal-hinged equivalent, and test static pressure before leaving.
- Guardsman extended vent runs (25+ feet, common in three-story Ashburn townhomes): Guardsman’s own installation manual specifies a maximum equivalent length of 25 feet with each 90-degree elbow adding 5 feet. Builders in the Loudoun Station corridor routinely exceed this. The result is chronic low airflow that no amount of cleaning fixes permanently. We measure equivalent length with a vent calculator, present the finding in writing, and quote rerouting to shorten the run or add an inline booster fan where code permits.
Our Guardsman Dryer Vent Cleaning Process

- 1
Visual and airflow inspection. We check the exterior termination, measure airflow at the cap with an anemometer, and note the Guardsman model numbers on the vent components. The reading goes in your job record.
- 2
Interior camera inspection. A flexible borescope enters the duct run to document lint accumulation, joint separations, or damage. You see what we see before any work is scoped.
- 3
Written price under Haven Standard Clause 1. We deliver a fixed price for the agreed scope. No per-vent add-ons, no trip charges, no “while we’re here” upsells. The price is the price.
- 4
Cleaning and repair. We use negative-pressure extraction with a Nikro HEPA vacuum and Rotobrush agitation tools sized to Guardsman’s 4-inch diameter. OEM Guardsman parts or quality aftermarket equivalents are used; the choice is documented.
- 5
Post-work testing and photo record. Airflow is remeasured, the vent run is re-photographed, and both readings are delivered with your invoice. The 365-Day Done Right Promise attaches in writing.

Why Ashburn Homeowners Call CleanRun Air Duct Cleaning Ashburn for Guardsman Work

We’ve worked on Guardsman vent systems in Ashburn since 2013, including the early builds at Loudoun Station where construction debris in shared wall chases still shows up in inspections. Our technicians carry Guardsman-compatible components on the truck, but we also stock Lennox, Trane, and Carrier termination hardware because many Ashburn homes have mixed-brand HVAC and laundry configurations.
Every job is backed by the 365-Day Done Right Promise in writing, not as a verbal assurance. Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. Tomas Reyes, our owner, reviews photo records from every Guardsman job before the invoice goes out - not for marketing, but because the photo is the proof that the work happened.
FAQs
No. Routine cleaning by an independent service provider does not void Guardsman’s product warranty, though damage caused by improper disassembly would not be covered. We document our methods and use OEM-compatible parts to maintain warranty integrity. If you have a specific warranty concern, call (240) 771-1508 and we’ll review your model’s documentation before scheduling.
Guardsman continues to support the GV, GFT, BG, and TWT lines for replacement parts, though some older transition duct colors have been discontinued. We verify part availability against your model number during the inspection and stock common substitutes if OEM is back-ordered. Call (240) 771-1508 with your model number and we’ll confirm before the visit.
Replace if the equivalent duct length exceeds 25 feet and cannot be shortened, if multiple joints are leaking, or if the termination is damaged and the replacement part is obsolete. Repair if the issue is isolated lint buildup, a single damaged elbow, or a binding damper. We present both options in writing with photos and let the data decide.
Every 12 to 18 months for a typical household, and every 6 to 12 months if you have pets, run multiple loads daily, or dry pet bedding or workwear. Ashburn’s pollen-heavy springs and dusty late summers add particulate load that flex ducts trap more readily than rigid metal. Call (240) 771-1508 to set a recurring schedule or book a one-time inspection.
You receive a documented photo record showing the interior of your Guardsman vent run before and after cleaning, plus anemometer readings of airflow at the termination before and after. If the photo doesn’t show a difference, the work isn’t complete. This is standard on every CleanRun job, included in the written price, with no extra fee.
