Dryer Vent Cleaning FAQ — Denver, CO
Common questions from homeowners in Denver and the surrounding area. If your question isn't here, call us and we'll give you a straight answer.
How often should a dryer vent in Denver actually get cleared?
Once a year covers most households. Push it to every six or eight months if you run more than five loads a week, if the dryer is stacked in an interior closet, or if the duct run is long and full of turns. The heating season here runs roughly October through April, so the stretch right before fall is the sensible window. You want the dryer moving air well when the house is closed up. Families with pets and anyone drying heavy towels or bedding regularly will build lint faster than average.

Which warning signs point to a clogged vent?
The big one is a load that used to finish in one cycle now needing two. Feel the dryer body and the clothes coming out: real heat in both means the moisture has nowhere to go. Other tells are a burnt or musty smell at the machine, lint piling up around the door seal, a laundry room that gets hot and damp while the dryer runs, and an exterior flapper that sits still instead of opening with airflow. Denver's low relative humidity hides mildew odors that would be obvious in a wetter climate, so trust the drying time more than your nose.

Walk me through the cleaning from the first knock to the last.
We locate both ends first, the dryer connection and the exterior termination, because in older Denver housing those two points are rarely where people assume. The dryer gets pulled out and disconnected, then we run a rotating brush on a flexible rod through the duct while a vacuum holds suction at one end so lint lands in the machine instead of your floor. The exterior hood comes apart, gets cleaned by hand, and goes back on with the damper working. Then we reconnect, run a cycle, and check airflow at the outside cap. If we find crushed duct, a disconnected joint behind the wall, or foil flex that should not be there, we show you before we pack up.

How long am I tied up for this?
A standard single-family job runs about 45 minutes to an hour and a half. A basement dryer in a 1950s brick ranch with a short straight shot to the rim joist is on the quick end. Three-story townhomes with a stacked closet unit and a vertical run to the roof take longer, since we often work both ends and sometimes from the roof. Add time if there is a nest, a collapsed section, or a hidden termination we have to track down.

Why do two vent cleanings on the same street land at different numbers?
Length and shape of the duct drive it more than anything. A pre-war bungalow with the dryer in an unfinished basement and a two-foot run through brick is simple work. A 2010s three-story townhome venting up through interior framing to the roof means roof access, fall precautions, and cleaning from above, which is a different job. Rodent or bird nesting, a crushed or disconnected section, a hood buried behind a deck or shrubs, and transition duct that needs replacing all move the number too. We look at it, tell you what we see, and you get the figure before we touch anything.

How do I know whether to call you or a dryer repair tech?
Try this: pull the duct off the back of the dryer and run a short cycle with the machine venting into the room. If it dries fine that way, the problem is in the duct and we can fix it. If it still runs cold, tumbles weakly, or trips out, the heating element, thermal fuse, or blower is the issue and you want an appliance tech. One wrinkle: a blocked vent often kills the thermal fuse, so a dryer that quit heating may need both the duct cleared and the fuse replaced. We will tell you straight if what we find does not explain your symptom.

Does it matter if my duct is rigid metal or flexible?
It matters a lot. Smooth rigid metal lets lint travel out. Every ridge in a flexible duct grabs it, and the foil accordion type behind the dryer is the worst offender because it sags, kinks, and tears. Semi-rigid aluminum is acceptable for the short transition between the machine and the wall, nothing more. Inside walls, floors, and ceilings the run should be rigid metal, screwless at the joints, taped with foil tape. We see white plastic and vinyl flex in Denver basements and garage-adjacent laundry rooms often enough that we check for it every visit, and we replace it when we find it.

What happens if something built a nest inside the duct?
House sparrows and starlings love a warm vent hood, and mice get in through a damper stuck open. We remove the nest material through the exterior hood, clear whatever got packed down the run behind it, and clean out the droppings and debris. If the animal is still in there and alive, we stop and refer you to wildlife removal first, since we are not licensed for that. Afterward the fix is a proper hood with a working damper and a guard that keeps birds out without trapping lint, because a plain screen clogs within a couple of months.

My duct run is way too long. Can it be shortened or helped along?
Often yes. The first move is always to count elbows, since each turn costs you the equivalent of several feet of straight pipe, and smoothing out an unnecessary jog sometimes solves the whole thing. Rerouting to a closer exterior wall is realistic in basements and garage-adjacent laundry rooms where the joists are open. In finished townhomes and condos with a stacked interior closet, rerouting usually is not practical, and a duct booster fan wired to the dryer is the better answer. We measure the effective length, tell you which path makes sense for your build, and we will say so if neither is worth doing.

Do you have openings today, and how far out do you travel?
Same-day slots are usually available, and morning calls have the best shot. We cover Denver and the surrounding metro: the older core with its late-1800s and early-1900s brick bungalows and Denver Squares, the 1920s-40s Tudor and minimal-traditional pockets, the inner-suburb belt of 1950s-60s brick ranches, the 70s-80s tri-levels and split-levels, the 90s-2000s two-story production neighborhoods on the outer ring, and the newer infill duplexes, townhomes, and mid-rise apartments along the transit corridors. Denver sits at roughly 5,280 ft on the western edge of the High Plains with the Front Range foothills immediately west, and shoulder-season snow in May or September can slow a roof-vent job. Call and we will tell you honestly what time we can be there.
