Unscrew the screw holding vent cover from the wall and pull the cover out. After removing the vent cap, clean all the old caulk from the wall. You can use a cleaning kit to do it easily.

It’s a better idea to seal around the outside of the new vent cover with paintable silicone caulk. Then, go back inside, push the vent cover pipe and the dryer duct together. After that, seal the joint with machine screws or duct tape.

Frequently asked the question:

What type of dryer vent hose is best?

Answer: At first know what a science selector says about drying your clothes to do your laundry more quickly and economically. The DryerFlex of the cap meets the 4-inch diameter specs. There is a flexible transition of hose between the dryer, and the wall outlet should be either the foil type or the aluminum type flexible duct.

So do not use the plastic or vinyl duct. Concealed ducting must be a rigid galvanized or aluminum metal duct. Therefore, these are the best dryer vent host for tight space.

Should dryer vent have a screen?

How do you seal the outside dryer vent?
