Dryer Vent Repair vs Dryer Vent Cleaning: What Is the Difference?
Clearing lint and fixing the vent itself are different jobs. Here is how to tell which one you need, and what to ask for.

Cleaning removes lint from a vent that is otherwise sound. Repair fixes the vent itself: a crushed, kinked, disconnected or leaking duct, a damaged outside hood, or flexible foil that should be metal. If the vent is clean but airflow is still weak, it needs repair, not another cleaning.
Key takeaways
- Cleaning clears lint. Repair fixes damage or a poor installation.
- A crushed, kinked, disconnected or leaking duct needs repair, however clean it is.
- Plastic and thin foil duct should be replaced with metal duct.
- Test airflow at the outside hood after any work, and keep the written price.
Cleaning or repair: which do you need?
| What you find | Cleaning or repair? |
|---|---|
| Lint built up along a vent that is otherwise intact | Cleaning |
| A duct crushed or kinked behind the dryer | Repair: reposition or replace that section |
| A joint that has come apart, or a leaking connection | Repair: reconnect and seal it |
| Plastic or thin foil flexible duct | Replace it with metal duct |
| An outside hood that is broken, blocked, or whose flap is stuck | Repair or replace the hood |
| A very long run or many bends | Have it assessed: it may need shortening or rerouting |
| Nesting animals in the hood | Clear the nest, and repair or protect the hood |
What is the difference between dryer vent repair and cleaning?
Cleaning removes lint from a sound vent. Repair fixes the vent itself, such as a crushed, disconnected or leaking duct, a damaged hood, or flexible foil that should be metal. If a vent is clean but airflow is still weak, cleaning again will not help: the vent needs repair.
Signs your vent needs repair, not just cleaning
- The dryer is still slow after a cleaning
- The air at the outside hood is weak even though the duct is clear
- The duct behind the dryer is flattened, kinked or pulled loose
- You see lint or moisture around the joints or inside the wall or attic
- The duct is plastic or thin foil, or has sagged
- The hood flap does not open, or the hood is damaged
See the vent safety guide and the vent cleaning page.
What a good vent job includes
- Looking at the whole run, from the back of the dryer to the outside hood
- Clearing lint along the entire run, not just the part near the dryer
- Checking joints and connections, and sealing or reconnecting any that leak
- Replacing damaged or unsuitable duct with metal duct
- Checking the outside hood and flap
- Checking airflow at the hood afterwards, and giving you the price in writing first
What should I ask for when I book a vent job?
Ask whether the whole run will be cleared, how the airflow is checked afterwards, what happens if the duct is damaged, and for the price in writing before work starts. Ask what a repair would cost if damage is found, so a cleaning does not turn into a surprise.
What it costs
Clearing a vent typically costs about $100 to $200 in Plano, with the price depending on the length and access of the run. A repair depends on what is damaged, so it is priced after the vent is inspected: replacing a short section of duct costs less than rerouting a long run, and a hood replacement is a separate item. Get any repair price in writing before it starts. See the cost guide.
How much does dryer vent repair cost?
Clearing a vent typically costs about $100 to $200 in Plano. A repair is priced after inspection because it depends on what is damaged, such as one section of duct, a hood, or a long run. These are estimates, not a quote, and you should get the exact price in writing before any work starts.
Do it yourself, or hire a professional?
Many people can clean a short, easy-to-reach vent with a brush kit and a vacuum, with the dryer unplugged and, for gas dryers, the gas valve closed. Roof vents, long runs, damaged duct and anything you cannot see are better left to a professional. See how to clean a dryer vent and foil vs rigid duct.

Frequently asked questions
Can I repair a dryer vent myself?
Simple fixes, such as reconnecting a loose joint or replacing a short section of duct, are within some people’s reach, with the dryer unplugged. Damaged or long runs, and roof vents, are better left to a professional.
How often should a vent be cleaned?
At least once a year, and sooner if drying times grow, after storms, or when the vent is long.
Is flexible foil duct acceptable?
It traps lint and can sag or tear, so metal duct is preferred. Check your dryer manual and local code.
Will a new vent fix a slow dryer?
If the vent was the restriction, yes. If drying is still slow with a clear vent, the cause may be a sensor, a heat part or the load.
