Book your dryer vent cleaning
Round Hill dryer vents fight cold attics, ice and the occasional three-foot snow.
Close to nine in ten homes in 20141 are detached houses, most built since the 1990s, and in a two-story house from those years the dryer vent line can run a long way before it finds an outside wall: across a ceiling, through a floor, or out over the garage. About four in ten Round Hill homes heat with propane, and where the dryer burns propane too, that line carries the burner’s exhaust along with the lint.
Winter is the hard season for a dryer vent here. The Purcellville weather station, about three miles away, logs around 115 nights a year at or below freezing. Warm, wet air from the dryer cools fast in a line that crosses an unheated attic or a garage ceiling, and the water it drops dampens the lint, which then sticks to the walls of the line instead of blowing out. A low spot or a sag collects it first.
Then there’s the hood. The blizzard of January 2016 left 36.3 inches of snow a mile west-northwest of Round Hill by a trained spotter’s measure, and freezing rain in February 2018 put up to fifteen hundredths of an inch of ice on the town. A low hood disappears under a drift, and a flap glazed with ice stays shut. The U.S. Fire Administration says to make sure the outdoor covering opens while the dryer runs; after a big storm, check it before the next load.
If a deck went in after the house did, see whether the dryer vent hood now ends underneath it, where lint and leaves pile up out of sight; inside the town limits a new deck needs the Town’s zoning permit first. The once-a-year advice on the card below comes from Ashburn’s volunteer company, part of the same Loudoun County fire and rescue system that staffs Round Hill’s Station 4, which moved in May 2026 from 4 Main Street to 41 West Loudoun Street.
Round Hill homes, by the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
Round Hill
ZIP 20141 as a whole: every Round Hill address, the Town and the neighborhoods around it. The Census place for the Town alone has too few homes for steady figures.
- Median home built2004 Census
- Built before 1980about 2 in 10 Census
- Built since 2000about 6 in 10 Census
- Most homes aresingle-family houses, about 9 in 10 Census
- Heated withelectricity, about 5 in 10 Census
- Rentedabout 1 in 10 Census
- Newer houses often put the laundry upstairs, so the dryer vent crosses a ceiling or climbs to the roof on its way out.
- In a single-family house the dryer vent run is often short, and the hose behind the dryer is where the trouble usually is.
What dryer vent cleaning costs in Round Hill.
The same prices as everywhere we work: $298 for dryer vent cleaning on its own, $199 when it’s added to an air duct cleaning, and included every year with Comfort+ membership at $199 a year.
- Dryer vent cleaning, on its own$298
- Dryer vent cleaning, added to an air duct cleaning$199
- Comfort+ membership, dryer vent cleaning every year included$199 a year
The price covers the whole dryer vent line, from the back of the dryer to the hood outside, with camera photos of what we find, a dated invoice, and before and after photos of your line when we can get a clear shot. Anything past the cleaning, like a new hose or a guard on the hood, you get the price first.
With Comfort+ membership, $199 a year covers the dryer vent cleaning every year, plus a water heater flush with a sewer camera inspection, a heating maintenance visit and a cooling maintenance visit, and we tell you when each one is due.
When a dryer vent needs cleaning in Round Hill.
The dryer runs hot after an ice storm
If drying times jump and the laundry room turns humid right after freezing rain, look outside first: a flap iced shut traps everything in the line. If the dryer stays slow once it’s clear, it’s due for its dryer vent cleaning.
The house is newer, the dryer vent isn’t clean
A 2005 house has run twenty years of laundry through its dryer vent, often a long run from an upstairs laundry room, and plenty have never been cleaned end to end.
Towels take two cycles
The first thing most people notice. When the dryer vent is packed, the damp air has nowhere to go, so the clothes stay wet and the dryer runs hot.
What the fire department says about dryer vents.
Loudoun County
Ashburn Volunteer Fire and Rescue, one of the companies in Loudoun County’s fire and rescue system, says the dryer vent, from the back of the dryer to the outside of the house, should be cleaned at least once a year, and that longer drying times are a sign it’s clogged. Source.
How to pick a dryer vent cleaning company in Round Hill.
Questions to ask anybody who quotes you, us included.
Will they check the hood from outside, even in January?
A dryer vent cleaning done only from the laundry room can miss a hood that’s crushed, iced or buried. Ask whether the tech walks around to it in any season and checks that the flap opens with the dryer running.
Do they clean the whole line, end to end?
Brushing the first few feet from the laundry room isn’t a dryer vent cleaning. Ask whether they clean from the back of the dryer to the hood outside, and how they get the lint out of the house instead of pushing it further down.
Do they show you what’s inside the line?
Camera photos of the inside of your dryer vent line are how you know it needed cleaning, and before and after photos are how you know the job was done. Ask to see them, and for a dated invoice if your HOA wants proof.

Dryer vent cleaning questions from Round Hill.
Can snow really block a dryer vent?
Yes, when the hood sits low on the wall. A drift over it leaves the hot, wet air nowhere to go but back into the line. Clear a path to it after a big snow, and if drifts bury it every winter, tell us when we come out.
Do you do dryer vent cleaning outside the town limits?
Yes, across 20141, from the Villages of Round Hill and Stoneleigh out toward Airmont, at the same $298, or $199 alongside an air duct cleaning.
How much does dryer vent cleaning cost in Round Hill?
$298 booked on its own, $199 added to an air duct cleaning, and included every year with Comfort+ membership at $199 a year.
