The call that started this job was a common one. A homeowner on Collina Landing Trail in Richmond told us their dryer had stopped keeping up. Loads that used to finish in one cycle were taking two, sometimes three. The laundry room felt warmer than it should. They figured the dryer was wearing out and were close to buying a new one.
The dryer was fine. The vent was the problem. And replacing the dryer would have changed nothing.
When we opened up the vent line, it was packed with lint from the dryer connection all the way out to the exterior wall cap. Airflow was choked down to a fraction of what it should have been. We cleared the full run, checked the wall cap, and the last photo in this set shows the duct interior after, clear and open again. The homeowner kept the dryer they already had.
The vent line packed with lint — airflow choked to almost nothing.

What a Dryer Vent Actually Does
Every time your dryer runs, it does two things at once. It tumbles your clothes in heat, and it pushes the hot, wet air that pulls out of them through a duct to the outside of your house. That second part is the one nobody thinks about, and it’s the one that matters here.
The air leaving your dryer is full of moisture and fine lint. Your lint trap catches some of it, but not all. The rest travels down the vent line, and over months and years, a layer of it builds up on the inside walls of the duct. As the passage narrows, the dryer has to work harder to push air through it. Dry times stretch out. The machine runs hotter. And the lint that’s collecting in there is extremely flammable.
That’s the chain of events behind a two-cycle dryer. It almost never starts with the appliance.
Why This Home’s Vent Was So Clogged
A few things make dryer vents in the Richmond and greater Houston area fill up faster than people expect.
The run length is one. A lot of homes out here, especially two-story builds in the newer communities, route the dryer vent a fair distance to reach an exterior wall or the roof. Longer runs with more bends give lint more places to settle and more opportunity to pack in.
The exterior cap is another. We see wall caps and roof caps that have been partly blocked by lint, by debris, and more than once by birds building a nest in the warm, sheltered opening. When the cap can’t open and vent freely, everything backs up behind it.
And then there’s time. Most homeowners have never had the vent cleaned, because nothing tells them to. There’s no light on the dryer for it. The buildup happens quietly until the symptoms get obvious enough to notice, which is usually right about the point this homeowner was at.
The Real Risk: Dryer Fires
Slow laundry is the annoyance. The fire risk is the reason this actually matters.
Lint is one of the most flammable materials in your house. Pack it into a duct, run hot air through it every day, add a dryer that’s running hotter than designed because the airflow is restricted, and you have the exact conditions behind thousands of home dryer fires every year. The U.S. Fire Administration puts the figure at roughly 2,900 dryer fires annually, and failure to clean the vent is the leading cause.
That’s not a scare pitch, it’s just the mechanism. A clean vent moves air, stays cool, and clears lint out of the house instead of storing it. A clogged one does the opposite.
How We Clean a Dryer Vent
A proper dryer vent cleaning is not the same as running a brush a few inches into the wall behind the dryer. For a job like this one, we clear the entire run end to end.
We start at the dryer connection and pull the machine out to get at the transition hose, which is often where the worst of it hides. Then we run rotating brush equipment through the full length of the duct while pulling the loosened lint out with a high-powered vacuum, rather than just pushing it deeper. We check the exterior wall cap to make sure the flap opens freely and nothing is blocking it. And we confirm airflow is restored before we call it done.
The before-and-after on this job was dramatic. The duct went from packed to clear, and the homeowner’s dryer went back to drying a load in a single cycle.

Signs Your Dryer Vent Needs Cleaning
You don’t have to wait for a problem to get bad before you catch it. A few signs are worth paying attention to:
Your clothes take more than one cycle to dry, or come out still damp. The top of the dryer or the laundry room itself feels unusually hot while it runs. You notice a burning or musty smell during a cycle. The exterior vent flap doesn’t open much when the dryer is on, or you can’t feel strong airflow from it outside. Or lint is showing up around the dryer and on nearby surfaces more than it used to.
Any one of these is worth a look. If you’re seeing several, the vent is overdue.
How Often Should You Clean It?
For most households, once a year keeps a dryer vent in good shape. If you run the dryer heavily, have a large family doing frequent loads, or your vent has a long or complicated run, every six to nine months is more realistic. And if you’ve just moved into a home and have no idea when, or whether, the vent was ever cleaned, it’s worth doing regardless of the calendar. There’s no way to know what’s built up in there until you look.
