Trusted Dryer Vent Cleaning for Longmont Homeowners
Lint builds up inside a dryer vent faster than most people expect, and in a dry, high-altitude town like Longmont it collects quickly. A clogged vent makes every load take longer, pushes heat back into the machine, and turns a routine appliance into a real fire risk. Our technicians have up to 9 years of experience and clean the full duct run, from the trap behind the dryer all the way to the exterior hood. We can often fit your cleaning the same day. Call (855) 360-7080 and we’ll book a free estimate.
What Our Dryer Vent Cleaning Service Includes
Every cleaning covers the whole vent path, not just the obvious lint trap. Here’s what each part of the service means and when you’re likely to need it.
Full Vent System Cleaning
This is the complete job: the entire duct run from the dryer connection to the outside termination is cleared of lint, dust and debris. You need it when drying times stretch out, when the exterior hood flap stops opening fully, or simply when it’s been a few years since the last cleaning. We use rotary brushes and air tools sized to your duct, and we run a camera through the line so you can see what was inside it before and after.

Lint Removal
Lint is the fine, fluffy residue that escapes the trap and settles along the duct walls. Over time it compacts into a dense layer that narrows the airway and holds heat. We pull that layer out with powered brushes and vacuum extraction, then check the duct’s interior surface to confirm it’s clear. If your lint screen looks clean but your clothes still come out damp, this is usually the culprit.

Lint Screen & Trap Cleaning
The screen and trap are the first line of defense, and they only work when they’re clean. A screen coated with fabric softener residue or packed with lint lets far more debris through to the duct. We clean the screen, clear the trap housing, and check the flexible transition hose behind the dryer for the kinks and clogs that build up there. It’s a small part of the visit but it makes the rest of the system work better.

Rooftop Vent Cleaning
Some Longmont homes vent the dryer up through the roof rather than out a side wall. Those runs are longer, often have more bends, and are harder to keep clear, so lint accumulates faster. We clean rooftop terminations and the duct leading to them, and we check that the vent cap is intact and not blocked. Getting to a roof vent safely takes proper equipment, so we handle it with ladders and fall protection rather than asking you to climb up.
Bird Nest & Debris Removal
Birds, wasps and rodents find dryer vent hoods appealing, and a nest in the duct blocks airflow almost completely. You’ll notice it when the flap won’t open, when you hear scratching or fluttering, or when the dryer suddenly can’t push air out. We remove the nest and any other debris, clear the full run, and make sure everything is out before we leave. If the hood is damaged or missing its screen, we’ll point that out so you can decide on a fix.
Booster Fan Cleaning
Long or complicated duct runs sometimes use an inline booster fan to keep air moving. The fan blades collect lint just like the duct does, and a clogged fan stops helping while adding more resistance to the system. We clean the fan housing and blades, confirm it spins freely, and check that it’s actually moving air. If the fan has failed, we’ll tell you plainly rather than cleaning around it.
Signs You Need Dryer Vent Cleaning Right Now
Most vent problems announce themselves before anything goes wrong. Watch for these:
- Clothes take two cycles to dry. A dryer that suddenly needs a second run is working against a restricted vent. The heat has nowhere to go, so it can’t do its job and the machine runs hotter than it should.
- The dryer feels hot to the touch. Excess heat on the cabinet or the top of the machine means the vent isn’t carrying it away. That’s the same trapped heat that makes lint dangerous.
- The exterior flap stays shut or won’t fully open. The hood flap at the outside wall should swing freely while the dryer runs. A stuck flap usually means lint or a nest is blocking the airway.
- You smell a burning or musty odor. A hot, dusty smell near the dryer points to lint collecting close to the heat source. Don’t run another load until the vent has been checked.
- It’s been more than a year since the last cleaning. Regular household lint buildup is steady and quiet. An annual cleaning keeps the duct clear before problems start, especially in homes with heavy laundry use.
Our Dryer Vent Cleaning Process – Step by Step
Here’s how a typical visit goes, so you know exactly what to expect.
- 1
We start at the dryer. We disconnect the dryer from its vent and inspect the transition hose and the back of the machine. That gives us a clear starting point and shows whether the clog is right at the connection.
- 2
We inspect the full duct run. A camera goes through the line so we can see lint depth, bends, damaged sections and anything else in the duct. You see the same footage we do.
- 3
We clean with the right tools for your duct. Rotary brushes and vacuum extraction clear lint from the whole run, sized to the diameter and material of your duct so nothing gets damaged in the process.
- 4
We clear the exterior termination. The hood, flap and cap get cleaned and checked so air can escape freely. We confirm the flap opens properly while the system runs.
- 5
We re-check and show you the result. The camera goes back through so you can see the difference, and we reconnect the dryer and test airflow. Nothing gets recommended without evidence you can see for yourself.
How Much Does Dryer Vent Cleaning Cost in Longmont?
A standard dryer vent cleaning in Longmont typically runs $95 to $175 depending on the length of the duct run and how accessible the vent is. Short, straight runs with a wall termination sit at the lower end. Longer runs, roofline terminations, or heavy lint buildup move toward the higher end because they take more time and equipment.
| Service | Typical Range |
|---|---|
| Standard vent cleaning (wall termination) | $95 – $145 |
| Long or complex duct run | $130 – $175 |
| Rooftop vent cleaning | $150 – $225 |
| Bird nest or debris removal | Quoted after inspection |
| Booster fan cleaning | Quoted after inspection |
What affects the price: the length of the duct, how many bends it has, whether the vent exits through the roof, and how much lint has built up. A written estimate sets the final price before any work starts, so nothing is a surprise at the end.
To avoid overpaying, get the run inspected and quoted as one job, and make sure cleaning the exterior termination is part of the price. If a contractor only cleans the trap and the first few feet of duct, you’re paying for partial work. Our estimate is free and covers the whole system, and the camera footage shows you what needs doing before you commit to anything.

Frequently Asked Questions – Dryer Vent Cleaning in Longmont
Dryer vent cleaning removes lint, dust and debris from the duct that carries hot, moist air from your dryer to the outside of your home. Over time that lint compacts along the walls of the duct and restricts airflow, which makes the dryer work harder and raises fire risk. The job covers the full run, from the connection behind the dryer to the exterior hood, not just the lint trap. Call (855) 360-7080 for an exact quote – estimates are free.
Most cleanings take 45 minutes to 90 minutes, depending on the length of the duct and how accessible the vent is. A short, straight run with a wall termination is usually on the quicker end. Rooftop vents and long, winding ducts take longer because they need more equipment and careful access. We’ll give you a realistic time window when you book.
Most cleanings in Longmont run $95 to $175, depending on duct length, accessibility and buildup. Rooftop terminations and complex runs can cost more because they take longer.

Yes, the vent cleaning doesn’t depend on which dryer brand you own. We disconnect and reconnect the dryer regardless of make or model, and the duct itself is what we clean. If we notice a problem with the transition hose or the machine’s connection, we’ll point it out so you can have it looked at.
Same-day cleaning is often possible when you call and we have an opening. We answer 24/7, and fast dispatch runs from 7am to 7pm, Sunday through Friday. We’re closed on Saturday, so a call that day gets booked into the next opening. The price is the same no matter when the work is done.
We stand behind the work, and if something about the cleaning isn’t right, call us and we’ll come back to make it right. The camera inspection and photo report we leave you with show the condition of the duct on the day we cleaned it, so you have evidence of what was done. We’ll explain the guarantee in plain terms before you book.
Clear the area around the dryer so we have room to work, and pull the machine out a few inches if you can. Empty the lint trap and remove any items stored on top of or beside the dryer. If your vent terminates on the roof, make sure we can access the ladder area safely. That’s all you need to do; we handle the rest.
