Start with your appliance manufacturer or a general handyperson

For a clogged or blocked dryer vent, a general handyperson or someone who does appliance maintenance can usually clear it. Many people call the same person who fixes their washing machine or refrigerator. If your dryer is still under warranty, contact the manufacturer first—they may cover the repair or recommend an authorized service center in your area.

A handyperson charges less than a specialized technician and can handle straightforward jobs like removing lint buildup from the vent hose, cleaning the vent cap on the outside wall, or replacing a kinked or crushed hose. If the problem is just blockage, this is often the fastest and cheapest route.

Key Takeaways

  • A general handyperson or appliance repair person can handle most dryer vent clogs and hose replacements without specialized equipment.
  • If your dryer is under warranty, contact the manufacturer before calling anyone else, since they may cover the work.
  • A chimney sweep or HVAC technician becomes necessary if the vent runs through walls, the attic, or the roof, or if you suspect a deeper blockage.
  • Get a quote by phone before scheduling—prices vary widely depending on what the problem is and how accessible your vent is.
  • If the vent is damaged or crushed inside a wall, you may need to reroute it, which requires someone experienced with building codes.

Call a chimney sweep if the vent runs through your roof or attic

If your dryer vent exits through the roof or runs a long distance through your attic or walls, a chimney sweep is often the right choice. They have the tools and experience to navigate vents that aren't straight runs, and they can spot blockages deep inside the duct that a handyperson might miss. Many chimney sweeps also clean dryer vents as part of their regular work.

Call a few in your area and ask whether they do dryer vent cleaning. Expect to pay more than you would for a straightforward hose replacement, but less than you would for rerouting the entire vent. A chimney sweep can also tell you if the vent is damaged inside the wall or attic—information you need before deciding whether to repair or replace it.

Contact an HVAC technician for vents integrated into your heating system

Some homes, especially older ones, have dryer vents that tie into the main ductwork or exhaust system. If that's your situation, call an HVAC technician rather than a general handyperson. They understand how the vent connects to your heating and cooling system and can clean or repair it without disrupting airflow to the rest of your home.

HVAC technicians also have access to video inspection equipment, which lets them see inside the duct without tearing into walls. This is useful if you're not sure where the blockage is or whether the vent is damaged. Ask the technician to show you the video so you understand what they found.

Know what to ask before you call

Before you pick up the phone, check a few things so you can describe the problem clearly. Walk outside and look at the vent cap—is it blocked with lint, or does air come out when you run the dryer? Go inside and feel the hose behind the dryer. Is it hot to the touch, or cool? A cool hose means air isn't flowing, which usually points to a clog.

Also note how long your dryer has been running longer than usual, or whether it's not drying clothes at all. When you call, tell the technician whether the vent is on an outside wall, the roof, or runs through the attic. This helps them estimate the job and decide whether they need special equipment.

What to expect when someone arrives

A technician will usually start by disconnecting the hose from the back of the dryer and looking inside. If lint is visible, they'll use a brush or vacuum to clear it. If the hose itself is damaged or crushed, they'll replace it—this takes 15 to 30 minutes and costs less than a service call for a deeper problem.

If the blockage is further down the vent, they may use a flexible rod with a brush attached, or a high-powered vacuum, to push or pull the lint out. If the vent runs through the roof or attic, they'll go outside or into the attic to access the vent cap and work from both ends. This takes longer and costs more, but it's the only way to clear a vent that's blocked deep inside the wall.

When you need to reroute the vent instead of repair it

If the vent is damaged inside a wall, crushed beyond repair, or routed in a way that violates building code, you may need to reroute it entirely. This is a bigger job that requires someone with experience in building codes and ductwork. An HVAC technician or a contractor who does ductwork can handle this, but get a written quote first—rerouting can cost several hundred dollars depending on how far the new vent needs to run.

Before you agree to reroute, ask the technician whether the current vent can be repaired instead. Sometimes a damaged section can be cut out and replaced without running new duct all the way from the dryer. This is cheaper and faster than a full reroute.

How to find someone in your area

Start by asking neighbors or your landlord if they've had dryer vent work done and who they called. Local Facebook groups and Nextdoor often have recommendations. You can also search online for "dryer vent cleaning" or "HVAC repair" in your city, or call your local hardware store and ask who they recommend.

Get at least two quotes before you decide. A quote should include what the technician found, what they'll do to fix it, and the total cost. If one quote is much lower than the others, ask what's included—they may be planning to do less work or use cheaper materials.

Frequently Asked Questions

Can I clean my dryer vent myself?

You can remove the hose from the back of the dryer and use a brush or vacuum to clear lint from the first few feet. But if the blockage is deeper in the vent or the vent runs through walls or the roof, you need someone with the right tools. Trying to force a brush through a long vent can damage the duct.

How much does dryer vent repair usually cost?

A straightforward hose replacement or lint cleaning by a handyperson typically costs $100 to $200. If a chimney sweep or HVAC technician has to access the vent through the roof or attic, expect $200 to $400. Rerouting the entire vent can cost $500 to $1,500 or more, depending on distance and difficulty.

What if the dryer vent is clogged and I can't find anyone to come out?

Stop using the dryer until it's fixed. A clogged vent is a fire hazard and also makes the dryer work harder and wear out faster. If you can't find a technician quickly, ask your landlord (if you rent) or your homeowner's insurance whether they have a preferred contractor list.

Do I need to turn off the dryer before someone works on the vent?

Yes. The technician will ask you to turn off the dryer and unplug it before they disconnect the hose. This is a safety requirement, not optional.

What's the difference between a dryer vent and a dryer duct?

The terms are used interchangeably. The vent (or duct) is the hose and the pipe that carries hot, moist air from the dryer to the outside. If someone uses one word and you're not sure what they mean, ask them to clarify whether they're talking about the hose behind the dryer or the pipe that goes outside.
