What it costs
The same prices as everywhere we work: dryer vent cleaning is $199, normally $298, with a year of Comfort+ membership included, or $199 added to an air duct cleaning.
Dryer vent cleaning, a year of Comfort+ membership included
$199, normally $298
Dryer vent cleaning, added to an air duct cleaning
$199
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.
What’s different in Round Hill
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.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.

When it’s due
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.
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.
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.
The dryer vent, locally
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.

Choosing who cleans it
Questions to ask anybody who quotes you, us included.
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.
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.
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.

Questions
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.
