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 Leesburg: What to Know First
CleanRun provides independent Guardsman dryer vent cleaning in Leesburg for homeowners who want the work documented, not just done. Most Guardsman exhaust systems we see in Loudoun County are completed same-day with a written price delivered before any panel comes off, typically between $189 and $349 depending on run length and what the inspection camera finds. We are not affiliated with or authorized by Guardsman; we are an independent service provider who stocks the fittings, transition ducts, and termination caps that match Guardsman specs.
This page is for Leesburg homeowners with Guardsman-brand dryer vent components, especially those in newer construction near Lansdowne, Belmont Country Club, or the Village at Leesburg where we’ve found builder-grade installations that don’t survive the first heavy lint cycle intact. Call (571) 487-7204 for a free estimate with a written price.
How Guardsman Products Fail - and How We Fix Them
- Guardsman GSV Series termination caps with flapper-style dampers bind after 18-24 months in Leesburg’s pollen-heavy spring seasons. The polypropylene hinge fatigues rather than corrodes, so the flapper sits half-open, letting rain into the duct run and creating a paste of lint and oak pollen at the first elbow. We replace with a corrosion-resistant louvered cap and photograph the elbow interior before and after extraction.
- Guardsman GSF flexible transition ducts in laundry closets with stacked units collapse at the ribbed sections where the dryer vibration works the material against the wall penetration. The camera shows a pinched airway, not a blockage, which explains why the dryer still heats but takes 90+ minutes per load. We reroute with rigid aluminum where space allows, or spec a Guardsman-compatible semi-rigid transition with a tighter bend radius.
- Guardsman GSV-EXT extended-run kits in three-story townhomes near Ida Lee Park were engineered for 25-foot runs but installed at 35+ feet by builders stretching material. The added static pressure overwhelms the dryer’s blower, and lint deposits unevenly at the mid-run splice joints. We break the run at each splice, clean with negative-pressure extraction, and install inline booster fans where the original design exceeds spec.
- Guardsman bird guard mesh on GSV caps in wooded lots off Route 15 clogs with cottonwood seed in late May, creating back-pressure that trips the dryer’s high-limit thermostat. Homeowners smell burning lint before they notice longer dry times. We clean the mesh without removing the guard’s structural frame, or replace with a Guardsman-compatible cap that uses wider-pattern screening.
- Guardsman GSD dampers in through-wall installations lose their foam seal after three to four years of thermal cycling. The leak path draws humid attic air into the duct in summer, condensing on lint deposits and accelerating buildup at the wall penetration. We replace the damper assembly and seal the penetration with fire-rated caulk, documented in the photo record.
Our Guardsman Dryer Vent Cleaning Process

- 1
Inspection with camera. The camera goes in before the quote comes out. We feed a borescope through the full duct run to locate restrictions, measure buildup depth, and identify Guardsman-specific components that need attention.
- 2
Written price delivered. Haven Standard Clause 1: the price is written and agreed before work starts. No exceptions. The scope specifies OEM Guardsman parts versus quality aftermarket equivalents, with the trade-offs explained.
- 3
Negative-pressure extraction. We connect a Nikro HEPA vacuum to the duct run and use Rotobrush agitation to dislodge lint without damaging Guardsman’s lighter-gauge aluminum in extended-run kits.
- 4
Component service or replacement. Worn dampers, transition ducts, or termination caps are swapped for Guardsman-compatible parts. We stock GSV, GSF, and GSD series fittings; if your system uses a discontinued line, we source quality aftermarket with matching pressure ratings.
- 5
Flow verification and photo record. We measure exhaust velocity at the termination cap with an anemometer and deliver before-and-after photos of every accessible duct section. The documented photo record is included as standard.
- 6
Written guarantee. The 365-Day Done Right Promise goes on the invoice. If airflow drops or a component we touched fails within a year, we return and make it right.

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

FAQs
No. Routine maintenance by an independent service provider does not void Guardsman’s product warranty, though damage caused by improper cleaning methods could. We use manufacturer-compatible tools and document our process so there’s a record of what was done and how. Call (571) 487-7204 if you need a copy of our cleaning protocol for warranty filing.
We stock OEM Guardsman fittings for current-series products and use quality aftermarket for discontinued lines, with the source noted on your written scope. The pressure rating, material gauge, and flame-spread index match or exceed Guardsman spec, and we show you the part before installation. No surprises.
Repair is viable when the duct run is intact and only the termination cap or transition duct has failed. Replacement makes sense when we find multiple splice failures, crushed rigid sections, or lint saturation in the duct liner itself. The inspection camera shows the difference, and we explain what we’re seeing before you decide. Call (571) 487-7204 for a free inspection.
Every 12 to 18 months for a household averaging five loads weekly. Leesburg’s heavy pollen season and winter static conditions accelerate buildup, so homes near wooded lots or with long GSV-EXT runs should lean toward annual service. We note the recommended return date on your job record.
We don’t price-match teaser rates. We do provide a Free Second Opinion on any written estimate: bring us a competitor’s detailed quote, and we’ll put our scope and price next to it in writing. The difference is usually in what’s included, what equipment is used, and whether you’ll receive a photo record of the actual work. Call (571) 487-7204 to schedule.
