Install a smooth metal dryer vent to hasten the drying process and stop lint accumulation. These detailed instructions will guide you through the challenging areas. Flexible plastic and metal vents trap more lint, need more maintenance, and might impede airflow. Rigid metal vents are safer. Even worse, flexible ducts are prone to squash, which restricts airflow, overheats the dryer, and can result in lint fires.

1.    From A Basement:

Run duct up the external wall and out the rim joist if your dryer is in an underground basement.

Place the vent at least 12 inches above the ground outdoors. For dryer vent installation, a pro suggestion is to use no more than 25 feet of 4-inch duct and to deduct 5 feet for every 90-degree turn and 2 1/2 feet for every 45-degree turn. For instance, a dryer can run 15 feet with a 90-degree elbow at the exhaust port and another at the top of the basement wall.

2.    Direct Route From The Basement:

Run the duct straight out of the back of the dryer if it is placed against an exterior wall that is not underground. Place the vent at least 12 inches above the ground outdoors.

Note that this is the best and most straightforward answer. For dryer vent installation, fewer turns and shorter distances are preferable.

3.    From The Roof Through The Attic:

Vent through the attic to the roof if the dryer is located in an interior room of the home.


Use the roof to vent a dryer only as a last option. Lint accumulation in roof vents is challenging to remove, and nesting birds and squirrels frequently find roof vent tops tempting.

Step 02:

Measure the run length, accounting for bends, after deciding on a vent position and planning the dryer duct path.

Purchase enough straight ducts, fittings, and an exterior cap to finish the project. Use either galvanized steel (which is what we recommend) or aluminum duct, but don’t combine the two materials.

Step 03:

In the rim joist, drill a test hole. Drill a test hole with a 1/4-inch bit after marking the rim joist’s center. Find the hole outside, then look for any obstacles.

Pro tip:

It’s not too late to correct the hole if it’s a little low or the cap if it doesn’t sit properly on the siding.

If it’s incorrect, you can patch the hole and begin again somewhere else.

Step 04:

To fit the siding, adjust the hole. Adjust the hole, so the vent cap’s top rests on the lap siding’s high point. To make measurement simpler, separate the vent cap and duct.

Step 05:

Drill the siding’s vent hole. Use a hole saw to bore a 4-1/4 inch hole.


Keep the drill steady and level. To remove sawdust and allow the drill motor to cool, pull the drill back frequently.

Step 06:

Cut a Hole in the Rim Joist As you continue, stop prying siding and sheathing out of the saw. Keep cutting through the rim.

Step 07:

To attach the cap to the home, insert the vent (predrill screw holes). Fill large gaps with a foam backer rod. Apply acrylic caulk all over.

Step 08:

Trim the Vent to Size. Before you sew the straight portions together, trim them using tin snips. Wear leather gloves; the edges of the sliced metal are sharp.

Step 09:

Glue the vent seam closed. Align the duct’s seam edges. Push the sides down just a little as you squeeze them together, starting at one end.

Step 10:

Engage the elbow joints with tape Beginning at the dryer, place the first elbow’s crimped end into the first straight segment. Use metal foil tape to seal the joints.

Step 11:

Push the dryer against the first fitting after sliding it on. Measure, cut, and put together the remaining duct sections.

Step 12:

Place the remaining vent sections in place. The final elbow should be slid onto the straight section of the wall. Insert the elbow’s crimped end into the duct cap part and tape it.

Step 13:

Straps are used to secure the vent to the wall. Every 6 to 8 feet, secure the duct with a pipe strap to walls or ceilings. Loop the strap around the duct rather than screw it.

Step 14:

Activate the dryer. Please turn on the dryer by plugging it in. Verify that the vent flap is opening from the outside.
