Fast, Reliable Dryer Vent Cleaning Across Longmont
If your dryer is taking two cycles to dry a load, the problem is usually the vent, not the machine. We clean dryer vents across Longmont, from the newer subdivisions on the east and south sides to the older blocks near downtown, and we clear the full run rather than just the section behind the dryer. Most of what we remove is packed lint at a bend, at the exterior hood, or at the point where ductwork turns up toward the roof. Dryer vent cleaning here starts with a look at how the duct was actually run, because that tells us where lint will collect. Call (855) 360-7080 to book a visit.
Why Longmont Homeowners Call Chimney Sweep Longmont for Dryer Vent Cleaning
Dryer vent cleaning is one of our three core services, alongside chimney sweeping and chimney repair, so it gets the same attention and the same professional tools as any other job we take on. Our technicians have up to 9 years of experience, and they’ve learned the local building patterns well enough to guess where a clog sits before pulling the dryer out. A lot of Longmont homes were built in the 1990s and 2000s, and those are the ones we see most often for vent work.
Customers in Longmont call us because we tell them what we find and show them the lint we pull. If the duct is sound and only the hood needs clearing, that’s what we say. When we recommend more, we explain the reason in plain terms. Our work is insured and bonded, and every job is priced by a written estimate before we start, so the number you agree to is the number on the invoice. We answer 24/7, with fast dispatch from 7am to 7pm.
Our Dryer Vent Cleaning Services in Longmont
Full Vent System Cleaning
This is the complete job: dryer disconnected, the full duct run cleaned from the appliance connection all the way to the exterior termination, and the blower housing and surrounding floor vacuumed out. In Longmont, where a lot of subdivision homes have long runs to a distant wall or up through the roof, cleaning the whole path matters more than a quick pass at the first section. You get a clear picture of what came out and whether anything in the run needs attention.

Lint Removal
Lint builds up in layers wherever airflow slows, and in flexible duct that was stretched or kinked during construction, those low spots fill first. We break up and extract the packed lint rather than pushing it further down the line. If we find a crushed section or a connection that has come loose, we point it out so you can decide what to do about it.

Lint Screen & Trap Cleaning
The screen and the trap area are where most homeowners look first, and they’re worth clearing properly. We clean the lint screen housing and the trap recess, then check that air is moving freely past the point where the duct begins. A screen that’s clogged with fabric softener residue can choke airflow even when the rest of the run is clean.

Rooftop Vent Cleaning
Many Longmont homes, especially the newer builds on the east and south sides, terminate the dryer vent at the roof instead of a side wall. That means climbing up, removing the cap, and clearing the lint and debris packed at the top of the run. Cottonwood fluff from the St. Vrain corridor collects around those caps between seasons, and it holds lint in place once it’s wet and matted. Rooftop work is where a lot of the real blockage lives.
Common Dryer Vent Cleaning Problems We See in Longmont Homes
Longmont’s housing mix shapes what goes wrong with dryer vents here. The newer subdivisions get built fast, and the ductwork doesn’t always survive the process in the shape it was designed for.
- Flex duct stretched or kinked during construction. Flexible duct gets pulled tight around framing and turns, and it sags into low spots where lint settles. Those traps fill quietly over a few years until drying times start climbing.
- Long runs that exceed the dryer maker’s length limit. A vent that travels up to the roof or across to a far exterior wall can run well past the length a dryer is rated to push air through. Airflow drops, lint builds faster, and the dryer works harder than it should.
- Exterior hoods clogged with lint and cottonwood fluff. Bird guards and flapper hoods catch debris from the dry, windy springs along the Front Range. Once the fluff packs in, exhaust has nowhere to go and the dryer overheats.
- Vents that have never been cleaned since the build. Plenty of Longmont homes from the 1990s and 2000s still have their original vent run with construction dust and lint from day one sitting in it. A relatively new house can be as clogged as an old one.
Why a Newer Longmont Home Can Still Need a Vent Cleaning
This is the part that surprises people. A house built in 2005 isn’t old, so the assumption is that the dryer vent must be fine. But the age of the house and the condition of the vent are two different things. In Longmont’s 1990s and 2000s subdivisions, the dryer vent often terminates on the roof or on a distant exterior wall, and the duct that carries it there is flexible, run through framing during construction. That duct gets stretched, bent around corners, and sometimes kinked at handover. Every one of those bends is a place lint slows down and settles. Nobody cleans it out, because nobody thinks a new house needs it. So the run fills, the dryer fights for airflow, and clothes take longer and longer to dry. The fix is straightforward: a full cleaning of the run and the termination, a check for crushed sections or loose connections, and a clear report of anything that needs repair.
Pricing for Dryer Vent Cleaning in Longmont, CO
A typical dryer vent cleaning in Longmont runs $95 to $225, depending on the length of the run, where the vent terminates, and how much lint has packed in. A short side-wall vent with easy access sits at the low end. A long run to the roof, a second-story termination, or a vent that hasn’t been touched since construction pushes toward the top of that range. Rooftop vent cleaning and heavier debris removal are quoted on their own once we see the setup, and a bird nest or a clogged exterior hood adds a bit of work. The estimate is free, the price is set per job in writing before we start, and there’s no service-call fee. If you want an exact quote for your house, call (855) 360-7080.

FAQs – Dryer Vent Cleaning in Longmont
Yes, it’s worth cleaning even though the house isn’t old. Subdivision homes from that era often have long flex-duct runs to the roof or a far exterior wall that were never cleared after construction, so lint and dust have been collecting at the bends and at the exterior hood the whole time. A cleaning tells you the actual condition of the run. Call (855) 360-7080 to book an estimate.
Longer drying times almost always come down to restricted airflow. East Longmont’s 1990s and 2000s homes tend to have long vent runs and flexible duct that sags or bends, and lint packs into those low spots and the exterior hood until the dryer can’t push air through efficiently. Clearing the run restores airflow. Call (855) 360-7080 for an exact quote on your setup.
Once a year is the general rule, and Longmont homes with long runs or rooftop terminations benefit from sticking to it. The dry, windy springs here drive cottonwood fluff into hoods and caps, and those homes also see heavier use through the cold winters. If drying times creep up sooner, get it looked at. Call (855) 360-7080 and we’ll help you decide.
It means getting to the roof termination, removing the cap, and clearing the lint and debris packed at the top of the run, then cleaning the full duct down to the dryer. Many newer Longmont homes vent this way, and the cap area is often where the worst blockage sits. Call (855) 360-7080 to book it.
Yes. Bird nests, cottonwood fluff, and general debris collect in exterior hoods and around roof caps, and once it’s packed in, the dryer has nowhere to exhaust. Blocked vents make the dryer overheat and are a real fire risk. We clear nests and debris as part of the cleaning. Call (855) 360-7080 for a free estimate.
If your dryer is working harder than it should, or you’ve never had the vent looked at since the house was built, get it on the schedule. Call (855) 360-7080 for a free estimate on dryer vent cleaning in Longmont. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday. We’ll clear the full run, show you what came out, and tell you plainly whether anything else needs attention.
