Cost to install dryer vent by location
A new dryer vent installation costs $200 to $800 on average, including cutting a hole in the wall. Installing an indoor vent costs $65 to $120 total but typically isn’t code-compliant in most places because of fire and mold risks.

|---|---|
| Outdoor vent through wall | $200 – $800 |
| Indoor vent | $65 – $120 |
Outdoor dryer vent cost factors include:
Vent location – Installing a vent under a deck or through the soffit increases labor costs.
Roof venting – Professionals install rooftop vents when necessary, but they don’t recommend it. Gas dryers cannot vent through the roof.
Accessibility – Ducts through floor joists, crawlspaces, or basements cost more.
Siding – Cutting a vent hole through vinyl or wood costs less than cutting through brick or stone.
Complexity – Duct elbows and complex ductwork configurations increase material and labor costs.
Cutting –Dryers that are not next to an exterior wall may need multiple cuts through walls or floors to vent outside.

Keep outside air from entering the dryer and ventilation system.
Prevent birds and other pests from nesting in the vents.
Stop any exterior debris from blowing into the vent and clogging it.
Rerouting dryer vent costs
The cost of rerouting a dryer vent depends on the project’s complexity. Moving a vent is typically necessary when upgrading an old home to meet building code requirements for ventilation.
Typical costs include:
The cost to move washer and dryer hookups is $500 to $2,000.
The cost to install a new electrical outlet is $150 to $350.
Gas line installation costs $150 to $1,000 for a new line to the dryer.

A DIY dryer vent kit costs $15 to $30 and includes flexible ductwork, clamps, and an outside vent cover. Extra parts may be necessary to fit the kit to the specific dryer model.
Indoor dryer vents are only safe to use with electric dryers, not gas models. Check local building codes before installing indoor vents to avoid fire hazards.
Dryer vent installation FAQs
How long can a dryer vent be?
A dryer vent can be up to 35 feet long maximum if it’s straight. Elbows in the ductwork or rooftop venting require a shorter vent length. Inspectors allow exceptions based on dryer-manufacturer recommendations. A booster fan is necessary for extra-long ducts.
How long does it take to install a dryer vent?
HVAC pros take 2 to 4 hours to install a new dryer vent where one didn’t exist before. Professionals can replace a pre-existing dryer vent in one hour in most cases. Extended timeframes are necessary to cut new holes in brick or stone siding.
Do you have to vent an electric dryer?
Yes, you have to vent an electric dryer. If moisture cannot exit the system, then clothes stay wet and encourage mold growth. Lint builds up inside the dryer and creates a fire hazard.
The only dryers that don’t need vents are heat-pump dryers and condenser dryers.
