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.
Air Duct Cleaning in Leesburg, VA
Dryer vent cleaning in Leesburg is a job shaped by the town’s housing boom of the late 1990s and 2000s, when Loudoun County was one of the fastest-growing counties in the country. Those large colonial homes in Lansdowne, River Creek, and Potomac Station now run 15 to 25 years old, and many still have the original dryer vent runs, often routed through unconditioned attic spaces or long exterior wall chases. We clean dryer vents, repair and seal ductwork, and treat indoor air quality in Leesburg with a written price before any work starts, plus a documented photo record of every duct run when we leave. The phone number to reach us is (806) 606-6902.
Why Leesburg Homes Are Different
Leesburg sits at the base of the Blue Ridge foothills, and that geography does more to your ductwork than most homeowners would guess. The town is bordered on multiple sides by Loudoun County’s active horse-farm belt, and technicians working the west Leesburg fringe near Raspberry Falls, Selma Estates, or along Route 15 north regularly find fine hay dust and dander packed into ducts at rates that surprise clients who moved here from denser Northern Virginia suburbs like Ashburn or Sterling. The particulates are finer than typical suburban dust, and they travel deeper into duct runs before settling.
Housing stock matters just as much. The dominant Leesburg home is a 1995 to 2010 builder-grade colonial or craftsman in a planned subdivision, running 3,000 to 4,500 square feet with two- or three-zone forced-air systems. Those systems have long branching duct runs, large return-air chases, and a lot of ductwork running through unconditioned attic spaces that bake in Piedmont summer heat. Summer humidity here regularly pushes into the high 80s in relative humidity terms, creating conditions that favor mold colonization inside ducts, especially in those attic runs. The historic downtown adds a smaller stock of pre-1900 structures where original or retrofit ductwork is frequently undersized or poorly sealed. A Leesburg job is structurally different from work in older, smaller-footprint markets nearby.
Our Main Leesburg Services
Most Leesburg homeowners call us first about two things: the ductwork behind their vents and the HVAC system that moves air through it. Here’s what each involves locally.
Air Duct Cleaning in Leesburg
Air duct cleaning in Leesburg means pulling years of accumulated debris, fine organic particulates from the surrounding horse country, and in many cases early-stage mold growth out of the full duct system. The larger colonials in planned subdivisions around town have extensive branching ductwork that takes longer to clean properly than a small pre-1900 downtown home. We photograph the inside of every duct run before and after, and the written price is set before a single panel comes off. Air Duct Cleaning in Leesburg covers the full process, local pricing, and what the before-and-after record looks like.

HVAC Cleaning in Leesburg
HVAC cleaning in Leesburg goes beyond the ducts to the air handler, evaporator coil, blower motor, and condensate pan. In a 3,500-square-foot two-zone colonial running through a humid Piedmont summer, those components collect a film of dust and organic matter that reduces airflow and gives mold a place to start. The coil is the most common problem spot we find in Leesburg homes, especially where attic air handlers run against unconditioned heat. HVAC Cleaning in Leesburg explains the process and typical costs.

Before
AfterDryer Vent Cleaning in Leesburg

Dryer vent cleaning in Leesburg matters because the town’s late-1990s through 2000s housing boom left thousands of large colonials with original vent runs that are now 15 to 25 years old, and many of those runs were never built for how long they would need to last. In a Leesburg home with a laundry room on the second floor, a dryer vent can run 20 to 30 feet through interior walls and an unconditioned attic before it exits, and every foot of that run collects lint. Leesburg’s rural-suburban edge compounds the problem: homes near Raspberry Falls or along Route 15 north pull in fine hay dust and dander that mixes with lint and loads the vent faster than homeowners expect. This is the single most common fire-safety and efficiency issue we document in Leesburg, and it’s why we clean and photograph every vent run the same way we do every duct run. See our full Dryer Vent Cleaning service page for more on what a documented vent record includes.
Dryer Vent Inspection
Signs you need it
Clothes are taking longer than 45 to 50 minutes to dry, the dryer exterior is hot to the touch, or you notice a musty smell coming from the dryer when it runs.
What it costs in Leesburg
A camera inspection of the full vent run in Leesburg typically runs $90 to $140, and we write the price before anything is opened.
How we do it
We feed a camera through the full vent run from the dryer connection to the exterior termination, recording the inside and showing you exactly where blockage or damage sits before any cleaning starts.
Lint Removal
Signs you need it
The dryer runs a full cycle and clothes still feel damp, or the exterior vent flap doesn’t open fully when the dryer is running.
What it costs in Leesburg
Full lint removal in Leesburg typically runs $110 to $190 depending on run length and location, and attic runs on the larger colonials add time.
How we do it
We run a rotating brush through the full vent path, then follow with high-pressure air and a HEPA-filtered vacuum at both ends to capture and photograph what came out.
Vent Rerouting
Signs you need it
The existing vent run is longer than building code allows, passes through unconditioned attic space where condensation collects lint, or terminates in a soffit or roof cap that has repeatedly clogged.
What it costs in Leesburg
Rerouting a dryer vent in Leesburg typically runs $240 to $420, depending on the new exit path and whether we’re working through brick, siding, or stucco.
How we do it
We map a shorter, code-compliant route, cut and seal the new termination point, reconnect the dryer with rigid metal duct, and photograph the finished run inside and out.
Bird Guard Installation
Signs you need it
You hear birds or scratching sounds near the exterior vent, or the vent flap is propped open by nesting material.
What it costs in Leesburg
Installing a bird guard on a Leesburg dryer vent typically runs $80 to $130 per vent, and the guard itself comes with the price written before work starts.
How we do it
We clear any existing nest material, clean the vent run, then mount a galvanized or stainless guard over the termination that blocks birds without restricting airflow.
What Dryer Vent Cleaning Costs in Leesburg
| Item | Typical range in Leesburg |
|---|---|
| Dryer vent inspection (camera) | $90 - $140 |
| Full lint removal | $110 - $190 |
| Vent rerouting | $240 - $420 |
| Bird guard installation | $80 - $130 |
How often should I clean my dryer vent in Leesburg?
Every 12 to 18 months for most Leesburg homes. If you’re near horse pastures, gravel lanes, or have a long second-floor vent run through an unconditioned attic, check it every 8 to 12 months because fine particulates load the run faster here. Call (806) 606-6902 for an exact quote; the estimate is written and free.
Will cleaning my dryer vent actually lower my energy bill?
A clogged vent forces the dryer to run longer, sometimes two full cycles for one load. A clean vent shortens dry time, which reduces the energy each load consumes. The savings depend on your dryer and run length, but the documented vent record shows the difference in airflow before and after. Call (806) 606-6902 to schedule a written-price inspection.
Duct Repair & Sealing in Leesburg

Duct repair and sealing in Leesburg is about fixing the leaks and damage that show up in the town’s dominant 1995 to 2010 housing stock, where long branching duct runs through unconditioned attics flex and separate over 15 to 25 years. Leesburg’s humid Piedmont summers make leaking ducts worse: when conditioned air escapes into a hot attic, the system works harder and humid outdoor air gets pulled into the return through the same leaks. Homes with two- and three-zone systems, common in the larger colonials around Lansdowne and Potomac Station, have more joints, more flex runs, and more points of failure than a smaller single-zone system. We inspect every duct run with a camera, write a price for what we find, and photograph the repair before and after. See our Duct Repair & Sealing page for the full service detail.
Duct Sealing
Signs you need it
Rooms on the upper floor never reach the thermostat set point in summer, or you see dust trails around return grilles.
What it costs in Leesburg
Sealing accessible ductwork in Leesburg typically runs $300 to $600, depending on how many runs and joints need treatment.
How we do it
We apply mastic sealant or UL-listed tape to every accessible joint and seam, then run a pressure test where the system allows it and photograph the sealed points.
Flex Duct Repair
Signs you need it
A run has collapsed, kinked, or torn in an unconditioned attic, or you can see a disconnected flex line when you look in the attic access.
What it costs in Leesburg
Repairing or replacing a flex duct run in Leesburg typically runs $180 to $350 per run, not including work in hard-to-reach attic chases.
How we do it
We remove the damaged flex section, pull new insulated R-6 or R-8 flex as needed, reconnect with proper collars and sealant, and photograph the finished run.
Mastic Sealant
Signs you need it
Joints are visibly gapped or the old tape has dried and peeled, and you can feel air moving around seams when the system runs.
What it costs in Leesburg
Mastic sealing of problem joints in Leesburg typically runs $150 to $300 per area, with the written price covering the specific joints we document as leaking.
How we do it
We brush or trowel mastic over the leaking seams, allow it to cure fully, and then re-test airflow at the register and photograph the sealed joint.
What Duct Repair & Sealing Costs in Leesburg
| Item | Typical range in Leesburg |
|---|---|
| Accessible duct sealing | $300 - $600 |
| Flex duct repair or replacement (per run) | $180 - $350 |
| Mastic sealing of problem joints | $150 - $300 |
How do I know if my Leesburg ducts are actually leaking?
Uneven room temperatures and dust around return grilles are the two most common telltales. We confirm with a camera inspection of the runs and, where the system allows, a pressure test that shows leakage in measurable terms. Call (806) 606-6902 for a written inspection estimate.
Why does it matter more in Leesburg than somewhere with milder summers?
Leesburg’s high summer humidity combined with unconditioned attic runs means every leak pulls humid outdoor air into the system while pushing conditioned air out. The result is mold risk, higher cooling bills, and rooms that never feel comfortable. Call (806) 606-6902 and we will put a written scope in front of you before anything is repaired.
Air Quality & Sanitizing in Leesburg

Air quality and sanitizing in Leesburg addresses a specific local condition: the town’s position at the base of the Blue Ridge foothills channels agricultural and equestrian particulates from Loudoun County’s active horse-farm belt into outdoor air that HVAC systems pull indoors. Homes in the west Leesburg fringe near Raspberry Falls and Selma Estates, adjacent to horse pastures and gravel farm lanes, show fine hay dust and dander inside ducts at levels that surprise homeowners who moved from denser suburbs. Add Leesburg’s summer humidity pushing into the high 80s in relative humidity terms, and the unconditioned attic duct runs common to the area’s 3,000 to 4,500-square-foot colonials become a mold colonization risk that eastern Loudoun towns like Ashburn rarely see to the same degree. We treat what’s actually in the air and on the surfaces, using equipment from Rotobrush, Nikro, and Guardsman where the job calls for it, and every treatment is documented with before-and-after photos. Full service detail is on our Air Quality & Sanitizing page.
Mold Treatment
Signs you need it
A musty smell comes from the registers when the system runs, or visible staining appears around supply vents or inside the duct runs during a camera inspection.
What it costs in Leesburg
Mold treatment in Leesburg typically runs $400 to $800 depending on the affected area, and we photograph the inside of every run before and after treatment.
How we do it
We identify the affected sections by camera, apply an EPA-registered antimicrobial to the duct surfaces, and address the moisture source so it does not return.
Odor Removal
Signs you need it
A persistent odor from cooking, pets, or a previous owner lingers even after standard cleaning, or the smoke smell from a one-time event has settled into the ductwork.
What it costs in Leesburg
Odor removal in Leesburg typically runs $300 to $650, depending on the source and how much ductwork surface needs treatment.
How we do it
We clean the duct surfaces first, then fog or apply a proven odor-neutralizing treatment through the system and photograph the inside surfaces before and after.
UV Light Installation
Signs you need it
You have a history of mold regrowth on the coil or inside the air handler, or a household member has allergies that flare when the system runs.
What it costs in Leesburg
UV light installation in Leesburg typically runs $500 to $900 per unit, including the Honeywell or similar UV lamp and hardwired installation at the coil.
How we do it
We mount the UV lamp inside the air handler or at the coil housing so the light shines directly on the coil surface, wire it to run continuously, and show you the unit in place.
What Air Quality & Sanitizing Costs in Leesburg
| Item | Typical range in Leesburg |
|---|---|
| Mold treatment | $400 - $800 |
| Odor removal | $300 - $650 |
| UV light installation | $500 - $900 |
Does the horse-farm dust really get inside my ductwork in Leesburg?
Yes, and often more than homeowners expect. Fine hay dust and dander particles are small enough to pass through standard filters and settle inside duct runs, especially on homes west of Route 15 or near pasture land. A camera inspection documents exactly what’s in your ducts. Call (806) 606-6902 for a written-price inspection.
Will air quality treatment remove the musty smell from my attic duct runs?
If the smell is coming from mold or organic buildup inside the runs, treatment plus source control usually removes it. The photo record shows the inside surfaces before and after, so you can see what actually changed. Call (806) 606-6902 for a written estimate.
