Trim the hose.

Using your tin snips (believe us, scissors won’t cut it here), carefully trim the vent hose along the line you marked off with tape.

Can you use foil tape on dryer vent hose?

While readily available, duct tape is not safe for dryer vents; use aluminum foil tape instead. When venting a dryer outside, it’s important to use the right kind of long-lasting, heat-resistant tape to seal the ducting and prevent lint and dust from spraying into the laundry room, walls, basement or attic.

Is it OK to insulate around a dryer vent?

Whether you should insulate your dryer vent or not depends on its location. If the dryer duct is within the home or a heated basement, there is no need or reason to insulate the duct/vent pipe. However, if the dryer duct runs through an unheated basement or crawlspace—insulation is highly recommended.

The maximum length of the exhaust duct does not include the transition duct. This means that vents should also be as straight as possible and cannot be longer than 35 feet. Any 90-degree turns in the vent reduce this 35-foot number by 5 feet, since these turns restrict airflow.
