Home › Services › Dryer Vent Cleaning
Lint packed into a dryer vent line is one of the more common home fire causes, and it makes every load take longer to dry. We clear the full run, not just the accessible few feet, and confirm airflow at the exterior hood before we leave.
Serving Broward, Palm Beach and northern Miami-Dade counties. Every job documented with before-and-after photos. Call (954) 686-6201.
From the dryer to the exterior termination, including any turns.
Cleared mechanically along the entire run, not just the visible section.

Airflow tested at the exterior vent before we call it done.
Every clothes dryer heats air, passes it through a tumbling drum and sends the moist, warm air out through an exhaust duct to the outside of the building. The lint screen inside the dryer catches much of the lint, but a share of fine fibers passes through and rides along in the airstream. Over many loads that material settles on the inside of the duct.
The duct is usually a few feet of pipe in a laundry closet, but it can be much longer. In many homes it runs through a wall, up through an attic, down through a floor or across a ceiling before it reaches an outside cap. Every elbow and every foot of pipe gives lint a place to cling.
Because the vent is hidden, most people only learn about it when a problem shows up. A dryer that once finished a load in a normal cycle now needs two. A laundry room feels hotter than it should. A burning smell appears. These are the moments when the vent gets attention, and they are good reasons to call.
It helps to know that the dryer is not the only thing that sends air through that pipe. The exhaust fan inside the machine is what pushes the air, and it can only push so hard. Every restriction in the duct makes the fan work against more resistance, so a vent that looks fine from the laundry closet may still be badly choked a few feet into the wall.
Lint is dry, light and easy to ignite. The dryer's heating element and the heated air inside a vent already create the conditions for trouble if airflow is blocked. When the exhaust cannot leave, heat builds up inside the machine and the duct, and a thick layer of lint sits right in that hot zone.
Moisture is the quieter issue. The air leaving a dryer is full of water vapor. If it cannot leave the building, that vapor condenses in the pipe, mixes with lint into a damp mat, and can leak into the wall, attic or laundry closet. In a humid region, added moisture is the last thing a building needs.
Neither issue needs to be dramatic to matter. A partial blockage can stay unnoticed for a long time while the dryer runs hotter, the cycle runs longer and the machine wears out sooner. That is why a periodic look is more sensible than waiting for an obvious failure, and why safety is the main reason to treat the vent as maintenance, not decoration.
South Florida adds one more factor. Outdoor air here is often warm and wet already, so a dryer exhausting into it has less margin before moisture lingers. A clear vent that moves air steadily keeps that moisture moving out, while a restricted vent lets it hover near the cap, the soffit or the wall, where it can feed stains and growth over time.
Clothes that are still damp or very hot at the end of a normal cycle are the most common sign. The dryer's outside surface or the top of the machine feeling hotter than usual is another. A smell of burning or scorched lint, even faint, deserves attention, and so does lint collecting around the dryer or in the laundry room.
Look at the outdoor exhaust cap while the dryer is running. You should feel a steady push of warm air and see the flap or louvers open. If the flap barely moves, or you see lint stuck around the cap, or birds and insects have used the opening, airflow is restricted somewhere along the line.
If you notice a burning smell, stop using the dryer, switch it off and keep the area clear. Do not try to remove hot lint or disassemble the machine. Call and describe what you observed, and have the dryer and vent inspected before you use it again.
Other quieter signs include a laundry room that feels humid, window or mirror fogging near the dryer, mildew smell on towels that were just dried, and exterior walls that show staining below the vent cap. Each one alone can have another cause, but together they suggest that moist air is not leaving the building the way it should.
The length and shape of a vent run change both the risk and the work. A short straight run to an outside wall behind the dryer is simple. A run of many feet with several turns is far more likely to hold lint and harder to clear completely, because brushes and air tools lose reach and effectiveness around bends.
Vertical runs through an attic or up to a roof cap bring their own challenges. Gravity works against the airflow, lint can sit at the bottom of a rise, and the exterior cap may be hard to reach safely. Technicians who work on roofs need to do so with care, and some runs are more sensibly reached from the outside.
Runs that have been rerouted over time, joined by mismatched pieces or squeezed behind a machine are common in older buildings and condos. When you describe the property, mention where the dryer sits and where you think the exhaust leaves the building. That gives the inspection a head start.
If you are not sure how long your run is, a rough guess is fine. Look at where the dryer sits relative to the nearest outside wall. A dryer against an exterior wall probably has a short run. A dryer in an interior closet may have a long one. Sketching or photographing the laundry area and the outside cap can also help the conversation when you call.
Gas and electric dryers behave a little differently when blocked, but the vent matters for both. A gas dryer also produces combustion gases that must leave the building through the exhaust, which is one more reason never to ignore a restricted vent. If you are unsure which type you own, check the label on the machine and mention it on the call.
The visit begins with a look at the dryer connection, the duct path and the outdoor cap. The scope and price are explained before work begins, so you know what is being cleaned and what is not. Photos are taken first so the starting condition is on record.
Cleaning typically combines a rotating brush or similar tool passed through the duct from one end and strong suction at the other, so loosened lint is drawn out and not pushed into the room. The lint trap housing inside the dryer, the connection hose and the outdoor cap are cleaned as well, since lint also hides in those places.
Afterward the system is reassembled, the dryer is checked for airflow at the outside cap and after photos are shared with you. If the technician finds crushed pipe, loose joints or an unsuitable material, you are told and shown what was seen, so you can decide on any repair, which is covered under duct repair and sealing where it applies.
Expect the visit to be orderly. Floors near the dryer are protected, the machine is moved only as far as needed, and it is put back where it was found. You should not be left with lint on the floor or a dryer that sits crooked against the wall. If a connector needs to be replaced, the new one should be the right size and shape and fitted without kinks.
The short connector between the dryer and the wall is often a flexible hose. Thin plastic or loose foil hoses tend to sag, crush and catch lint, and they can restrict airflow badly. Smooth rigid metal duct usually moves air better because lint has fewer ridges to grab. What your local building requirements say about materials varies, so ask your building department or property manager rather than assuming.
Pushing a dryer tight against the wall is a common cause of crushed connectors. Even a good connector can kink when the machine is shoved back, and the kink becomes a lint trap. Leaving a little room behind the machine and checking the connector shape is a simple habit that helps.
Screws used to hold duct sections together can poke into the pipe and snag lint. Tape that has dried and lifted can leak warm moist air into walls. These small details are why a technician looks along the whole run, not only at the vent opening.
Cap design matters as well. Caps with fine screens can fill with lint and block the exhaust, which is one reason screens are generally discouraged on dryer terminations. Whether a particular style is acceptable for your building is a question for your building department or property manager, and a technician can point out which style you currently have.
In multi story buildings, dryer vents may share a vertical shaft or run through common walls to a roof or side wall outlet. Some are the owner's responsibility, some belong to the association, and the dividing line is not always obvious. Ask your management company who handles which part before scheduling work.
Laundry closets in condos are often narrow, with a stacked washer and dryer and very little room behind them. Work in such spaces is slower and more careful. Mention the layout when you call, and clear the area in front of the closet so equipment can be brought in without moving furniture.
Building rules on contractor access, elevators, work hours and protecting common hallways differ from one community to another. Plan for them early. A small amount of preparation with your property manager can prevent a delayed visit and keep the work from disturbing neighbors.
Property managers who look after many units can find the commercial systems page useful, since multi unit buildings raise the same questions about shared shafts, access and responsibility. A written note of which units were inspected and what was found gives the board or the owner a clear record to keep.
No single schedule suits every household. A couple using the dryer a few times a week produces much less lint than a large family doing loads every day. Pets, towels and blankets create more lint than lightweight clothing. Longer runs need attention more often than short ones.
Between professional visits, clean the lint screen after every load, not once a week. Occasionally wash the screen with water and a soft brush to remove the film that dryer sheets leave, since that film can block airflow even when the screen looks clean. Check the outdoor cap and keep plants, mulch and clutter away from it.
If you notice the dryer taking longer, do not assume the machine is failing. Check the screen and the cap first, then call for an inspection if the problem remains. Replacing a good dryer because of a blocked vent is a costly mistake that happens more often than you would expect.
When you do schedule a cleaning, bring up any history you know: a dryer that was moved, a laundry room that was remodeled, a vent that was extended, or a past problem with birds or pests in the cap. These details explain surprises that the technician might otherwise meet inside the wall, and they help the scope be accurate from the start.
The dryer vent is separate from your cooling ducts, but the two share a home and often a visit. If you are planning air duct cleaning, ask whether the dryer vent can be inspected during the same appointment. Doing both gives a fuller picture of how air moves through the property.
Damp, musty air near the laundry area is sometimes a vent leak and sometimes a drain or air handler issue. If you notice a smell near a closet that holds both a dryer and an air handler, mention it. Coil and blower cleaning may be relevant if the cooling equipment shares that closet.
If a vent is damaged, crushed or disconnected, cleaning will not fix it. Repair of exhaust pipe is a different task, and you should expect the technician to say so plainly. Broken sections should not be left in service, because a clean but broken pipe still leaks heat, lint and moisture.
If your concern extends to what you breathe, indoor air quality testing can look at conditions inside the home, and the air duct cleaning scope guide helps you compare what different providers include when you are booking several services together.
When you call, say what kind of dryer you have, where it is, how long the run is as far as you know, and what symptom you have noticed. If the exhaust leaves through the roof, say so. If you rent, mention it, because you may need your landlord's approval. Nothing more is needed to start.
After the work, look at the photos. A clean duct should show bare metal or clean pipe wall along its length, an open cap with moving louvers, and no lint left in the connection. The before and after photo guide explains how to read pictures like these with a sharper eye.

Common signs are damp clothes after a full cycle, a dryer that runs hot to the touch, a burning or musty smell, and lint around the machine. Run the dryer and check the outdoor cap: you should feel a steady push of warm air. Weak or no airflow suggests a restriction somewhere along the run.
Cleaning the screen after every load is good practice, but it does not remove lint that already lines the duct. A clean screen only protects the dryer's own filter. Fine lint that passes through settles in the pipe over time, so the duct itself needs periodic attention, especially on long runs with turns.
No. Stop using it, switch it off and keep the area clear. Do not try to disassemble the machine or dig out hot lint. Call, describe what you noticed, and have the dryer and vent inspected before using it again. A burning smell should be treated as a safety matter, not an annoyance.
Both. The technician works from the dryer connection inside and checks the outdoor cap, and sometimes cleans from the outside end as well. Furniture and floors near the laundry area are protected, and lint is drawn out with suction, so it does not drift into the room. Tell us about roof or high wall outlets when you call.
You will be told and shown what was seen, usually with photos, and the options are explained before anything proceeds. A crushed or disconnected section cannot be fixed by cleaning alone. Depending on the damage, a repair or replacement of that section may be discussed, and you decide whether to go ahead.
It depends on the building. In some communities the owner is responsible for the duct inside the unit, while shared shafts and roof outlets belong to the association. Rules vary from one community to the next, so ask your management company or board before scheduling any work, and share their answer when you call.
