A dryer vent close, also referred to as a dryer vent cap or drier vent cap, which is made to let the warm air from the dryer escape during the drying cycle, subsequently avoid the cold outdoor air from entering when the dryer isn’t running. They also prevent animals from taking up residence on your drier. These covers and caps come in a variety of shapes and sizes that fit onto any drier vent pipe. They all attach in basically the exact same way, and just basic tools are necessary.

Eliminate the old closure, if relevant, using a screwdriver to remove any screws that are holding it on and cutting any sealing caulk from the close with a utility knife. Pull the close shed and off.

Place the new close over the protruding vent pipe. If you can, use the old mounting screw holes; if not drill new screw holes using a drill with a pilot hole bit. Make sure the bit is 1/8-inch smaller in diameter than the diameter of the screws that are to be used to mount the new close into position. Hold the new close around this wall, mark the mounting holes with a pencil and then drill through those to your pilot holes.

Place the new close over the vent pipe. Screw in the mounting screws to hold it in position. Seal the edges with silicone caulk.
