A homeowner in the 77498 zip code in Sugar Land called us about a dryer that was taking two, sometimes three cycles to actually dry a load of towels. The dryer itself tested fine. The vent line was the problem, and once we got the cap off, it wasn’t hard to see why.
Every dryer vent cleaning job starts at the exterior cap, since that’s usually where the worst of it collects — lint pushes through the line and piles up right at the exit point, where airflow slows down the most.
That gray haze coating everything around the cap and screws isn’t just surface dust. It’s fine lint that’s worked its way out of the airflow and settled into every gap, which is usually a sign the line further back is a lot worse.
Sure enough, a few feet in, the vent had narrowed down to almost nothing.
That fluffy white material bridging the opening is compacted lint that’s built up layer over layer, probably over several years. It almost looks decorative in the photo, like a strange little nest, but functionally it means the dryer is fighting to push air through a gap the size of a straw instead of a full duct. That’s the exact setup that makes dryers run hot and take forever to finish a load — and it’s also the setup the National Fire Protection Association points to as a leading cause of home dryer fires.
Further down the line it didn’t get any better.
This kind of buildup doesn’t happen in one season. Lint accumulates a little at a time, and because the dryer still runs and the laundry still (eventually) dries, most homeowners never know there’s a problem until something forces the issue — a burning smell, a dryer that shuts off mid-cycle, or in the worst case, a vent fire.
We ran our equipment through the full length of the line, working it in stages rather than one straight pass, since compacted lint like this doesn’t clear in a single push. Once we were done, the difference was obvious.
That’s the same line, fully open, metal visible end to end. The dryer at this house should run a full cycle faster now, and more importantly, it’s no longer sitting on top of a fire risk every time someone does laundry.
Dryer vent cleaning doesn’t get talked about as much as air duct cleaning, but it matters more — especially in homes where the vent run is long, has a few turns in it, or hasn’t been touched since move-in. If your dryer is taking longer than it used to, or you can’t remember the last time anyone looked at the vent line, it’s worth a look before it becomes a bigger problem.
