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.

Our Dryer Vent Cleaning Services in Sterling
Dryer Vent Inspection
Every Sterling job starts here. We run a camera through the full vent pathway from the dryer transition to the exterior cap, documenting what we find before quoting any work. In Sterling Park homes off North Sterling Boulevard and along Church Road, we regularly discover original 1970s foil flex duct that has kinked, sagged, or separated at attic joints - not just dirty, but structurally failed. The inspection gives you the photo evidence and a written scope before you decide. That’s Haven Standard Clause 1: written price before work starts, always.
Vent Cleaning & Lint Removal
Standard lint removal in Sterling runs $180-$260 when the vent run is intact and accessible. We use Rotobrush and Nikro professional-grade equipment - negative-pressure extraction with rotary brush agitation - to break up and remove lint buildup throughout the run. But in Sterling’s older homes, we often find lint packed into low spots where the flex duct has sagged or collapsed, creating dense masses that simple brushing won’t clear. When that happens, we show you the camera footage and quote the additional work before proceeding. No surprises. No per-vent gimmicks. One flat price per system.
Vent Rerouting
This is where Sterling’s housing stock distinguishes itself. Original flex-duct dryer vents in 1960s-1980s Sterling Park townhomes and ranches frequently pass through unconditioned attics with deteriorated insulation, where humid NoVA summers promote condensation and lint matting into dense, hardened layers. The duct itself often collapses or separates at connection points. Vent rerouting in Sterling typically runs $280-$480 depending on run length, attic accessibility, and whether we’re replacing foil flex with rigid or semi-rigid vent per modern code. We re-hang with proper slope, secure joints with metal tape (never screws that catch lint), and verify airflow at the exterior hood before we leave.
Vent Cap Replacement & Bird Guard Installation
Missing, broken, or improperly screened caps are an invitation for birds and rodents in Sterling’s mature-tree neighborhoods. We stock replacement caps and Guardsman bird guards sized for standard 4-inch venting, with same-day installation in most cases. A proper cap with functioning damper and bird guard runs $120-$220 installed, including verification that the damper opens fully under dryer airflow and seals when off. In a 1978 Sterling Park townhome off North Sterling Boulevard, our tech pulled a Guardsman bird guard and found the original foil flex vent sagging and disconnected mid-run in the attic, packed solid with lint. We ran a camera inspection, cleared the lint pathway back to the transition, and replaced the crushed section with rigid semi-rigid vent before re-hanging the cap, then verified airflow at the exterior hood.

Common Dryer Vent Cleaning Problems We See in Sterling Homes
- Collapsed foil flex in Sterling Park attics. Original 1970s foil flex dryer vent in Sterling Park attics kinks or separates at joints, so lint accumulates in low spots instead of reaching the exterior cap. We find this in roughly half the pre-1985 homes we enter in the neighborhood.
- Humidity-matted lint from NoVA summers. Northern Virginia’s famously humid summers - regularly 90°F+ with dew points in the low-to-mid 70s - create ideal interior-duct conditions for mold and mildew, especially in Sterling’s older homes where vapor control and duct insulation were well below modern standards. Heavy spring pollen from the dense oak and maple canopy throughout Loudoun County infiltrates duct systems whenever homeowners open windows during the shoulder season, adding a second annual contamination cycle on top of the humidity-driven one.
- Route 28 corridor dust binding to lint. Years of commercial and data-center construction dust along the Route 28 corridor infiltrates the lint pathway, binding to humid lint and making airflow restriction worse than the visible trap lint suggests. Your dryer may be working harder than the lint screen indicates.
- Disconnected runs in unconditioned spaces. Original duct runs in Sterling’s older homes frequently pass through unconditioned attic spaces with deteriorated insulation, accelerating condensation, mold, and debris buildup. The same failing joist-to-vent run that fails dryer venting also fails supply air in these homes.

FAQs - Dryer Vent Cleaning in Sterling
Because the original 1970s foil flex duct is often structurally compromised at connection points rather than just dirty. In a typical Sterling Park attic, we’ll find the vent has sagged, kinked, or separated at a joint, so lint packed the gap instead of exiting. Cleaning alone won’t restore airflow through a collapsed run. We show you the camera footage, quote the reroute in writing, and proceed only with your approval. Call (240) 318-7712 for an inspection and exact quote - estimates are free.
Sterling Park’s original mid-1960s-to-1980s flex duct is often structurally compromised at connection points rather than just dirty, and the same failing joist-to-vent run that fails dryer venting also fails supply air in these homes. In Sterling’s older townhomes, dryer vents frequently share that legacy flexible foil construction and have collapsed or separated inside unconditioned attics, so a dryer vent cleaning call routinely becomes a partial reroute-and-replace job. Newer Ashburn and Brambleton homes use rigid or semi-rigid vent from the start, properly sloped and supported, with fewer failure points. Call (240) 318-7712 for an inspection and exact quote - estimates are free.
Yes. The relentless commercial and data-center construction activity along the Route 28 Dulles Tech Corridor generates persistent fine particulate that infiltrates these aging residential duct systems, creating a uniquely high-demand environment for duct cleaning that neighboring cities with younger housing stock don’t share. This dust binds to humid lint inside your vent run, accelerating restriction beyond what lint alone would cause. If your dryer cycle times have crept up despite a clean trap, this combined buildup is a likely cause. Call (240) 318-7712 for an inspection and exact quote - estimates are free.
It keeps birds, rodents, and debris out while letting moist exhaust escape. Sterling’s mature oak and maple canopy provides nesting habitat; we’ve pulled packed nests from unscreened caps in neighborhoods from Sterling Park to Cascades. A proper Guardsman bird guard with functioning damper also prevents backdraft of cold air in winter and humid air in summer, both of which condense inside your vent and accelerate lint matting. Installation runs $120-$220 with airflow verification. Call (240) 318-7712 for an inspection and exact quote - estimates are free.
We verify with three documented checks: camera inspection showing the full run clear to the exterior cap; airflow measurement at the hood with the dryer running, confirming the damper opens fully under load; and the before-and-after photo record delivered to you as part of the standard job documentation. If we replaced or rerouted sections, those joints are photographed too. This is the Documented Photo Record included on every visit, a practice CleanRun has held since its first job in 2013.
