The technician pulled a gray clump out of my outside vent hood last Tuesday and held it up like a fish. It was the size of a softball. That was twelve months of lint from a vent run I had rebuilt a year ago, the kind of run that is supposed to stay clean. The visit took 35 minutes and cost $135, and it’s the one bill in my fall routine I no longer argue with.
A year ago I was on the other side of this. I paid for three cleanings on a bad vent before I figured out the vent itself was the problem. So I’ve seen dryer vent cleaning cost money that fixed nothing, and I’ve seen it cost money that was worth every dollar. Below is what a normal cleaning runs in 2026, what moves the price, when a $30 kit does the job, and why I book mine in September.
What my dryer vent cleaning cost this fall
$135, flat, for a first-floor side-wall vent about eleven feet long. No trip fee, no “inspection fee” on top. Here is what that bought:
- The dryer pulled out and the transition hose behind it disconnected and cleaned.
- A rotary brush on flexible rods run through the whole duct, from inside and then from the outside hood.
- A vacuum on the inside end the whole time, so the lint went into a bag and not onto my laundry closet floor.
- The lint trap housing inside the dryer cleaned out, which is where a surprising amount of it sits.
- The flap on the outside hood checked: it opens, it closes, nothing painted over it.
- A before-and-after airflow reading at the hood, written on the invoice.
That last line is the one I now ask for. It’s a number I can compare against next year.
Before the rebuild, my cleanings ran $130 to $200 and came back clogged within six weeks. That story is in my post on what my dryer vent installation cost, and it’s the reason this post exists. On a good vent, a cleaning is cheap maintenance. On my bad one, it bought about six weeks each time.
Dryer vent cleaning cost by vent type and location
My $135 sits right on the national middle. HomeGuide’s dryer vent cleaning cost guide, which pulls from 1,184 reported project costs, puts the national average at $130, with most people paying $80 to $185. Where your vent comes out of the house matters more than anything else:
- Basement or first floor: $80 to $150.
- Second floor: $110 to $185.
- Roof vent: $150 to $250, because someone has to get on the roof.
- Cleaning plus a bird nest removal: $120 to $250.
- Inspection only: $30 to $60.
- DIY brush kit: $15 to $50.
The same guide lists rerouting or a new installation at $200 to $500, and a dryer vent plus whole-house air duct package at $340 to $800.
Two things push a quote toward the top of any range: a long run and a lot of bends. Every turn is a place for lint to stop and a place the brush has to fight through. If you measure your run and count the elbows before you call, you can give every company the same two numbers, and the quotes start to line up.
Why I book the dryer vent cleaning in fall
The NFPA’s clothes dryer safety sheet says to clean lint out of the vent pipe once a year, or sooner if clothes start taking longer than normal to dry. It doesn’t say which month. I picked September for three reasons.
First, my dryer works hardest from October to March. Sweaters, flannel sheets, towels that never air-dry on the line because there is no line. I’d rather start that stretch with an empty duct.
Second, the outside hood. The same NFPA sheet reminds you to check that the outdoor flap isn’t covered by snow, and a flap already half-blocked by lint is the one that ices shut first. Mine is at ankle height on a side wall that drifts.
Third, it’s easy to book. Cleaners are slammed in spring, when everybody reads the same “spring cleaning” list. In September I got a Tuesday morning slot four days out.
And it fits with the rest of my fall home reset checklist: smoke detector batteries, furnace filter, dryer vent, all in the same weekend so none of them depends on me remembering in February.
The U.S. Fire Administration lists failure to clean as the leading factor in home clothes dryer fires from 2018 to 2020, at 31 percent. A yearly cleaning is the fix for that one.
DIY or pro: what a $30 kit can do
I own a kit. It cost me $28 and it’s a set of flexible rods, a round nylon brush and an adapter for a cordless drill. I use it for the short job, the transition hose and the first few feet behind the dryer, about every four months. That’s where my lint piles up fastest, because it’s the part that gets bumped when I pull the dryer out to mop.
What I stopped doing is running it through the whole duct myself. Two reasons. On my old foil run, I pushed the brush through a bend, it caught, and I pulled the hose apart inside the wall. That was a whole afternoon and a drywall patch. And I have no way to check airflow at the hood, so I couldn’t tell whether I’d done anything.
My rule now:
- Short, straight, first-floor run you can see most of? A kit is fine, once a year, and you save most of the $130.
- Long run, hidden in walls, more than two bends, or a roof exit? Pay someone. The brush can get stuck or pull a joint loose, and you won’t know until the laundry room gets humid.
- Gas dryer? The NFPA sheet says a qualified professional should inspect the gas line and connection. I’d book the pro just for that.
What pushes a dryer vent cleaning quote up
Last year I collected four quotes for the same eleven feet, and this year I called three companies before booking. The spread came from the same few places every time.
The biggest one is the upsell. Two of the three companies this year asked, on the phone, whether I’d like to “bundle the air ducts while we’re there.” One offered the package at $389. Dryer vents and heating ducts are separate systems with very different prices. I wrote about the air side in what air duct cleaning cost me, and I book that on its own schedule.
The second is the add-on hardware: a bird guard, a lint alarm, a new hood. Some of these are useful. A new hood is worth it if yours has a screen or a flap that sticks. But none of them is the cleaning, and they’re easy to agree to while someone is standing in your laundry room.
The third is the trip fee. One company quoted $99 and then mentioned a $59 service charge. The one I booked quoted $135 and that was the invoice.
Reading your dryer vent cleaning quote, line by line
This is the table I keep on the inside of my laundry cabinet door. These are the lines I’ve seen on quotes and invoices over two years, and what I say to each.
| Line on the quote | What it usually is | My call |
|---|---|---|
| Full duct cleaning, inside and out | The job itself: brush, vacuum, hood check | Keep. This is what you called for |
| Transition hose cleaning | The short hose behind the dryer | Keep, but it should be included, not extra |
| Airflow reading before and after | A number measured at the outside hood | Ask for it. Free proof the job worked |
| Inspection or diagnostic fee | Someone looking before quoting | Fine alone at $30 to $60; skip if you’re booking the cleaning |
| Bird nest removal | Nesting material in the hood or duct | Only if they show you the nest |
| New hood or bird guard | Hardware at the outside end | Yes if the flap sticks or has a screen; otherwise no |
| “Bundle with air ducts” | A second, unrelated job | Skip. Price it separately, some other day |
| Trip or service charge | Fee for showing up | Ask on the phone; walk away if it appears later |
Three dryer vent cleaning mistakes that waste money
- Booking cleaning after cleaning on a bad vent. If drying time creeps back within two months, the duct is the wrong shape or the wrong material. Get it looked at for a rebuild before paying for a fourth brush-out.
- Letting the phone decide the price. A quote given without asking where the vent exits or how long it runs is a guess. Give them your length and bends first.
- Saying yes in the laundry room. Add-ons are easiest to agree to while someone is packing up. Decide before the visit what you’ll say yes to.
What didn’t work for me
The leaf blower. Somebody online swore you could blast a vent clean by pointing a leaf blower into the dryer end. I tried it on the old foil run, two falls ago. A cloud of lint came out of the outside hood, which felt like progress. Most of the rest got pushed into the low spot where the foil sagged, and the next load took three cycles. Air alone doesn’t scrub the walls of the duct. It moves the loose stuff and packs the rest.
The other thing was waiting for a symptom. For a whole year I only booked a cleaning when towels came out damp. By then the vent was already restricted. Now it’s a date on the calendar, the same week every September, symptom or not.

FAQ
How much does dryer vent cleaning cost on average?
HomeGuide puts the national average at $130, with most homeowners paying $80 to $185. First-floor vents run $80 to $150, second-floor vents $110 to $185, and roof vents $150 to $250. I paid $135 this fall for an eleven-foot side-wall run on the first floor.
How often should a dryer vent be cleaned?
The NFPA says once a year, or sooner if clothes take longer than normal to dry. I book mine every September and clean the short hose behind the dryer myself every few months, since that’s where lint builds fastest in my setup.
Is professional dryer vent cleaning worth it?
For a long run, a roof exit, a vent hidden inside walls or a gas dryer, yes. For a short, straight first-floor vent you can see, a $15 to $50 brush kit can handle it once a year. If a pro cleaning only lasts a few weeks, the problem is the vent itself, and a cleaning won’t fix that.
If you’ve never had yours done, go look at your outside hood today while the dryer is running. If the flap barely lifts, or you see lint around the edges, book the cleaning this week and ask for the airflow number on the invoice.
